The turntable bearing is a large bearing with a special structure. It can withstand a comprehensive load such as a large axial load, radial load, and overturning moment. It also has a variety of functions such as support, rotation, transmission, and fixation. Applications in the seed industry or equipment are widely used. Many friends are not very familiar with how to disassemble large -scale turntable bearing. Next, Hengguan Xiaobian will introduce the four commonly used bearing disassembly methods for everyone.

1. Tapping and disassembling method

In many disassembly scenarios, the knocking method will be used. In short, using a copper stick or other soft metal materials less than the inner diameter of the bearing to the shaft end (if the bearings are at the end of the axis), use the handhand to knock on the bearing in the bearing. The circle slowly falls off. This method is simple and easy to do. The disadvantage is that it is easy to cause damage to the bearings. Therefore, you should be careful when operating. You need to pay attention to the rolling of the bearing and keeping the rack.

Second, pull out the disassembly method

This method needs to use a specialized tool to generate a uniform pull force by rotating the handle to pull out the bearings. This method is better to protect the bearing, and you need to pay attention to the following points when operating:

1. To hook the hook of the stretch to hold the inner ring of the bearings, if the accidental hook may cause excessive or damage to the bearing loosening on the outer ring.

2. To make the screw rod on the center hole of the bearing, pay close attention to the force of the bearings during the process of pulling out to avoid damaging the hooks and bearing.

3. Pay attention to prevent the hook from slipping, the corner of the bend of both feet should be less than 90 °

Third, pressure disassembly method

This method needs to use the pressure machine to press the bearing. The working process is smooth and reliable, and generally does not damage the machine and bearings. Pay attention to the effort point of the pressure machine should be on the center of the axis, and cannot be compressed. Common pressure machines are manual, mechanical or hydraulic type.

Fourth, heat treatment and disassembly method

The bearing for disassembling tightness can be performed first, and then pulled out with the help of the tension. Generally, the oil that is heated to about 100 ° C is poured on the bearing to be demolished. After the bearing ring is heated and expanded, the bearings are evenly pulled out with the help of a dedicated tape. This method should do a good job of self -protection and oil body recycling to prevent scalding; wrap the shaft body before heating, so that the bearing can not disassemble the bearings caused by heating and expansion.

The above is the specific introduction of how to disassemble the large -scale turntable bearing, I hope to help you. Luoyang Hengguan Bearing Technology Co., Ltd. is a comprehensive physical enterprise integrating design, research and development, production, sales, and service. The product quality is guaranteed. If you still have other questions about bearing, you can give it. We leave a message or call us, we will serve you wholeheartedly

Recently, Luoyang Hengguan Bearing Technology Co., Ltd. (hereinafter referred to as: Hengguan Bearing), which is a low -noise rotation support for a large medical equipment manufacturer in South Korea, has successfully went offline and all meet the requirements of the customer’s use.

The low noise rotation support bearing is supported on the CT machine. The ordering party requires that the noise must be controlled within 60 decibels, otherwise it will be rejected. This product plan begins with the inquiry from the Ministry of Foreign Trade of our company. After several rounds of negotiations and discussions, in -depth understanding of customer use conditions and requirements, through video conferences, accurately understand the pain points and demands of the client, and then combine our technical staff of our company. Professional research and judgment, signed this order after half a year.

After receiving the order, our Si immediately arranged a high -quality forging material to strive to grasp the quality barrier from the source. First of all, the top priority of these products is how to control the noise and noise reduction is Guan Jian. Our technical staff fully combines professional skills and practical experience, formulated a complete processing process, and marked the main points that should be paid attention to in each process. The bearing rolling road is a very important process during the bearing processing process, which is related to the life, performance, accuracy, and stability of a set of bearing. Followed by the batch of low -noise rotary support for the bearing, it is vertical installation. In order to ensure the smooth rotation, our company specially customized a batch of overall nylon maintenance racks. Third, our company has made special improvements in maintaining the shelf, which can greatly reduce operating noise and ensure that the operating noise is controlled within 60 decibels. (Popularization of common sense: When we usually talk normally, the sound intensity is about 80 decibels)

After a series of tight and orderly processing and production, the batch of products are successfully completed and offline. After testing, all requirements were within the scope of the drawing of the guests, and the Henglee challenged again! The important thing is that we keep our promises and realize the customer’s demands. We believe that in the future, we will export more high -quality rotary support for the bearings, go to the world, carry forward the Chinese manufacturing industry, promote the spirit of the craftsmen of the great powers, and let the world fall in love with Chinese manufacturing!

After a period of use, the turnaround will find the surface of spots or discoloration on the surface, which not only affects the territory and smoothness of the bearing surface, but also directly affects the effects of the bearing and the service life. So, how to increase the brightness of the turn support surface? Is there any good way to solve it? Next, follow the editor to learn about it.

1. Plating

Electroplating is a layer of light protective film required to form a light protective membrane on the surface deposition layer required by the surface of the thorough support to the surface of the base. This method can not only increase the brightness of the rotating support surface, but also play a role of surface rust. Electroplating can be divided into single metal plating, multi -layer combination electroplating, and alloy plating.

There are many factors that affect the quality of the coating, such as: pre -plating treatment, the purification method and degree of plating fluid, the rationality of the governance method, the establishment of the plating system, the determination of the combination and thickness, the process parameters (pH value, temperature, current density) , Additive (light brightener, tideline, dehumidifier, wetting agent, dispersant), plating liquid analysis and supplementary system, operating system, post -plating treatment (de -hydrogen, closure), etc. Of course, this electroplating layer only plays a protective role on the surface of the rotating branches. It has not changed the internal structure of the bearings. During the daily use process, the wear of the bearing will still affect the brightness of the bearing and the risk of rust.

2. Machine shaping

Through the mechanical method, the metal surface layer changes changes, thereby increasing the hardness and high -intensity sclerosis layer. The degree value is reduced, so that the surface brightness of the bearings can be improved from the outside, and it can also improve the surface fatigue strength of the parts and reduce the sensitivity of the fatigue gap.

The first two are how to increase the surface brightness before the unused reckle support, and during the use process, it can only be maintained through later maintenance and cleaning to do a good job of the brightness of the bearing surface.

3. Do a good job of anti -rust work

(1) Clean

Select the suitable solvent for cleaning during the use of rotation support. This will not destroy the rust -proof process on the rotating support surface, and at the same time, it will not cause serious corrosion phenomena. Doing the surface cleaning of the bearings can restore the brightness of the bearing surface.

(2) Lubrication work

Do a good job in the maintenance of the bearings in the daily use process, and regularly lubricate the bearings. Before that, the editor of the Ronda also shared the oil lubrication method of the turntable bearing. In addition to lubricating work in daily use, we must also pay attention to maintaining the dryness of the bearing surface, which can also increase the brightness of the bearing surface.

The metallic gloss of the rotating support bearing steel is actually very bright. The reason why we have the need to increase the brightness of the bearing surface, and most of the reasons are caused by the rust and cleaning of the bearings during the use process. Rust and cleaning work is also very important for improving the surface brightness of the rotating support. Doing the cleaning and maintenance of the bearings during the use of the bearing can increase the brightness of the bearings. At the same time, the rust -proof treatment of the bearing surface before use can also increase the brightness of the rotation support surface.

 

In construction construction, excavators often appear, not only its crawlers are not afraid of some potholes, but also because excavators can rotate left and right, it is very convenient to dig pits and fill soil. There will be a variety of problems with the reckless support of the excavator, and there are more abnormal noises. Then let’s take a look at the reasons and solutions why the excavator rotation support has abnormal noise!

The reasons and solutions of the excavator’s rotation support

1. Inlerance of installation, loose screws installed

When there is abnormal noise, it is necessary to determine whether it is not installed enough to meet the requirements of the machine’s use, which causes a gap in the rolling road, which leads to abnormal noise. In addition, when the small gear bite process is not tight enough, it is not tight enough There is also the possibility of generating abnormal noise. In severe cases, the gear breaks; in addition, when the bolt of the fixed reckless support is loose, it will also cause the gap between the elastic deformation of the rotation support. At this time Essence

2. There are foreign bodies inside the internal inheritance

When the inside of the rotation support enters the foreign objects such as sand and gravel, iron Mozi, at this time, not only will there be a strange vibration sound, but also the problem of stuttering in the west of the rotation direction. Therefore, if we want to avoid this situation, we must not only clean up the bearings and matching parts before installation, but also remember to clear the foreign objects in the lubricant in time; The shelf, so that we can remove the corresponding abnormal noise.

3. The abnormal noise caused by the lubrication problem

The rotation support of the excavator needs to be lubricated with lubrication, so the abnormal noise may also be caused by the problem of lubrication. The more common reasons are problems such as lack of grease, uneven lubricating fat, poor lubricating fat quality and aging and lubricant selection errors. Therefore, as long as we use the right lubricant, add and replace the new lubricant in time, we can avoid such abnormal sounds.

4. The abnormal noise caused by the damage of the seal bar

The structure of the turnaround support sealing strip plays a key effect on the sealing nature. Therefore, it is necessary to regularly check whether there is wear around the sealing strip, because when the sealing strip and the rotary support are not closely fitted, it will cause lubricating fat to lubricate fat Leaks a certificate outward, and there will be abnormal noise. In addition, the aging and butter resistance of the sealing bar is also a problem that we need to consider.

5, cracks, indentation or rust of abnormal noise

The rolling surface of the rotation support, if cracks, indentation or rust appear, will cause vibration of the rotary support, which will cause noise. However, this noise will cause uncertain changes with the difference in installation and grease. Therefore, we must not tap bearing or use the grease with high viscosity during installation.

6. Severe wear of rolling roads and rolling bodies

The reasons for abnormal noise of the excavator’s rotation support may also be due to the long -term use of the rotation support. The rolling road and the rolling body have reached the life of the use. Repair.

The above content is integrated by the editor. There is an abnormal reasons for the rejuvenation of the excavator and the relevant information of the solution. In addition to these, it is more important to pay attention to the daily use. Maintenance and maintenance. This is the end of today’s sharing. If you still have questions, please consult us at any time!

Recently, Luoyang Hengguan Bearing Technology Co., Ltd. (hereinafter referred to as Hengguan Bearing), designed and manufactured for a large group company in Northeast China, the special slewing bearing for the 6-meter disc ball machine (ball-forming disc) has been successfully completed and passed the finished product. It has been sent to a third-party construction site for installation and trial operation.

The disc pelletizer refers to the equipment used to manufacture green pellets in the pellet production process. Disc pelletizers are widely used in non-ferrous metallurgy, cement, steel, fertilizer and other industrial fields. In the process of application, the design of disc pelletizers has been continuously innovated and perfected, so that the disc pelletizers have reliable functions. , High-quality equipment with rigorous structure, excellent effect, less wear, low energy consumption and easy maintenance. The new disc pelletizing machine is mainly composed of disc body, transmission system, slewing bearing, rotary scraper device, disc body inclination adjustment device, lubrication system and other parts. This time, Hengguan Bearing mainly manufactures one component of the slewing ring bearing. Hengguan Bearing has produced 6-meter and 7.5-meter ball machine slewing ring bearings.
The 6-meter ball machine slewing ring bearing is designated by the owner of our company’s slewing ring bearing, and the ball machine manufacturer is entrusted to purchase it. Since the owner’s on-site ball machine has been shut down due to a problem with the slewing ring, a new set of slewing ring bearings is urgently needed for replacement, so as to resume normal operation as soon as possible. After receiving the order, our company immediately arranged the time to put materials into production; and made innovations and improvements according to the actual use of the old slewing ring bearings on site. Shipped smoothly within 25 days of the order taking effect.

For the on-site problem (1): the slewing bearing is prone to jam and standstill during the operation; this phenomenon occurs because the ball machine is not running horizontally when it is in working state, but during the operation. It is caused by a certain angle of inclination; in the normal slewing bearing raceway, it is composed of rolling elements and spacer blocks; when all rolling elements are tilted and transported, due to the action of gravity, it will cause extrusion, jamming, standstill, etc. Happening. Hengguan Bearing has innovatively improved the slewing bearing cage, so that each rolling element can keep rotating in place, so that this problem can be easily solved.
For the on-site problem (2): the oil leakage of the raceway is serious when the slewing bearing is running; due to the inclined operation of the slewing bearing of the ball machine, the ordinary rubber sealing strip is not tightly sealed, and the raceway leaks under the action of gravity. The oil phenomenon is serious, which is not good for bearing lubrication. In response to this phenomenon, the engineers of Hengguan Bearing proposed to use a double-layer special seal, the internal use of the secret palace type wool seal, and the outer ring to be sealed with a steel plate by direct pressure; the on-site oil leakage phenomenon was properly solved.
There are always more solutions than difficulties. Hengguan Bearing, aiming at the actual use of slewing bearing, solves the problem; constantly emancipates the mind, enhances the sense of innovation, the spirit of innovation and the ability of innovation. Achieve innovation in work ideas, innovation in goals and tasks, and innovation in work measures. By innovating the working mechanism, constantly adapting to new situations, studying new situations, summarizing new experiences, exploring new laws, expanding one’s own brain power, and improving work quality and efficiency, Hengguan people strives for each set of slewing ring bearings that leave the factory to allow customers satisfy. Our aim is: to solve problems for customers, to create value, to be a valuable enterprise! Hengguan Bearings, intelligently create the future, only work hard for high-quality slewing ring bearings!
