How to increase the brightness of the slewing bearing surface? Is there any good solution?

/in /by

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.

Necessity and Adjustment Method of Gear Clearance Adjustment of Slewing Bearing

/in /by

When installing slewing bearings with teeth for tower cranes, excavators and other equipment, it is necessary to adjust the gear clearance correctly. So do you know the necessity of adjusting the gear clearance of the slewing bearing? How to adjust it?


​
1. The necessity of adjusting the gear clearance of the slewing bearing
​
1. Different applicable work scenarios
​
The size of the gear clearance of the slewing bearing is related to the characteristics of the gear transmission. When the gear transmission is used for heavy-duty work, the gear clearance needs to be larger. The gap should be smaller.
​
2. Improper gear clearance affects normal work
​
The gear transmission of tower cranes and excavators is not only required for heavy-duty work, but also requires frequent forward and reverse rotation, and the speed is not high. Whether the clearance is too large or the clearance is too small, it will have adverse effects. If the gear gap is too large, the operation of these equipment will not be very smooth, and the gear wear will be more serious; if the gear gap is too small, the lubricating oil film between the slewing bearing gear and the slewing reducer gear will be destroyed, causing The friction between the two becomes larger, and the tooth surface wears faster. Coupled with manufacturing errors and elastic deformation of the turntable, it is very likely that the gear will be stuck.
​
Therefore, for heavy machinery such as tower cranes and excavators, in order to ensure the reliability of equipment rotation, it is very necessary to keep the gear gap of the slewing bearing at a moderate size and debug it according to the actual working conditions.

2. Adjustment method of slewing bearing gear clearance
​
1. Meshing tightly to adjust the gap
​
In the position with high gear meshing tightness, adjust the gear backlash to the rated value. The value of this value should be adjusted strictly according to the given value, otherwise it may cause damage to the slewing bearing. In addition, in the process of gear clearance adjustment, it is also necessary to pay attention to the position of the teeth.
​
2. Use feeler gauge to measure and adjust
​
When the radial runout of the slewing bearing gear reaches a high point, the gear gap can be measured with a feeler gauge. If the gap is different from the given value, the slewing reducer gear can be moved to change the center of the slewing reducer gear and the slewing bearing gear. Correct the distance. If the slewing reducer gear cannot be moved, it can be adjusted by moving or re-fixing the slewing bearing. After debugging, let the slewing bearing rotate a few times to see if the adjusted clearance meets the requirements. If there is a radial jump of the gear to a higher point, it should be marked and adjusted again.
​
When adjusting the slewing bearing gear clearance, if there is no gnawing between the slewing bearing gear and the slewing reducer gear, and the slewing mechanism can run smoothly, it means that the gear clearance has been adjusted properly.
​
Through this article, I believe that everyone already knows the necessity and adjustment method of slewing bearing gear clearance adjustment. Timely adjustment of slewing bearing gear clearance can avoid equipment failures caused by inappropriate gear clearances and ensure the reliability of equipment rotation.

　　回转支承

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!
Slewing ring
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.
