How to choose the material of the large spindle shaft？

/in /by

Recently, many customers have asked how to choose the material suitable for the large spindle shaft, and how to choose the hard spindle material suitable for their products. Today, Hengchang Heavy machinery will introduce to you how to choose the material.

The hardness of the large spindle shaft is a relatively important parameter. Whether the hardness is appropriate is directly related to the quality of the product.


The hardness of the motor spindle will vary depending on the material, and the process selected during processing will also be different. At present, the common process treatments include the hardness of the raw material itself and the heat treatment process to harden. Some products have special structures, such as the need to punch ribs on the surface of the product, so the material of the motor spindle cannot be too hard, and some motor shafts have retaining rings, so the hardness range of the motor spindle is between HV500-600. It is more appropriate. If the material selected for the motor spindle is SUS420 series stainless steel, then the hardness range of HV260-320 is more appropriate. But remember that the hardness of the motor spindle cannot be too high. Sometimes the bearing capacity requirement is not very high, so it is enough to slightly temper the motor shaft. Some parts have special requirements, which can be quenched and chrome-plated.

Hengchang heavy machinery is a large-scale mechanical processing manufacturer, specializing in processing various large spindle shaft , gear shafts, spline shafts, gears, and racks. Welcome to consult!

What role does the big gear ring play in ball mill and rotary kiln equipment?

/in /by

The big gear ring is one of the important transmission parts in mining machinery rotary kiln, ball mill, dryer and other equipment. Its quality is directly related to the continuous stability time and service time of rotary kiln, ball mill and other equipment, so the quality requirements for big gear ring products will be relatively high. Big gear rings are widely used in the machinery industry, for example, they have very important applications in electricity, chemical industry, automobile, etc.

Because the quality of the big gear ring directly affects the operation of the equipment, every detail must be accurately controlled during processing and production, and there must be no mistakes, otherwise the quality inspection will fail when the casting is completed. When producing big gear rings, ball mill parts manufacturers must require the quality of the big gear ring to pass layers of quality inspection, and only when the test requirements are met can it be shipped and used.

The large gear ring itself is composed of two half-size rings. The vertical mill parts manufacturer will be more complicated in the production process. For example, the blank is made from the process of making wooden molds, modeling, casting, and pitting, and then heat treated to improve the comprehensive performance of the large gear ring. After a round of rough processing, fine processing is carried out, and various inspections are carried out until a high-quality large gear ring can be cast.

Ball mill parts manufacturers have experience in producing tens of thousands of large castings, so they have become proficient in the production process of large gear rings. If you have a purchase demand for large gear rings, you can contact us and we will quote you free of charge!

6 major considerations for purchasing non-standard customized gears

/in /by

Gears are an important part of mechanical transmission and there are many types of them. Among them, non-standard gear customization has gradually become the mainstream of the market. However, if we accidentally choose unqualified products during the purchase process, it will bring great troubles to our work and life. In order to help everyone avoid these problems, this article will introduce you to the 6 major considerations for purchasing non-standard gear customization.
1. Quality must be guaranteed
When purchasing non-standard customized gears, the first thing to consider is its quality. A high-quality gear should have the characteristics of high strength, wear resistance, and low noise. Therefore, before choosing, be sure to check the supplier’s production process and quality management system to ensure that its products meet relevant standards and requirements.
2. Ensure accurate size
Non-standard gear customization often needs to be designed and manufactured according to different usage requirements. Therefore, when purchasing, pay special attention to the dimensional accuracy of the gear. If the size is inaccurate, it will lead to assembly difficulties or poor transmission effect. Therefore, we should choose suppliers with advanced equipment and rich experience to ensure the dimensional accuracy of the product.


3. Understand the material characteristics
The material of the gear directly affects its service life and use effect. When choosing non-standard gears, we should understand the characteristics and applicable scenarios of different materials. Common materials include alloy steel, stainless steel, cast iron, etc. Each material has its advantages and disadvantages. We need to choose the right material according to actual needs.
4. Consider transmission efficiency
When purchasing non-standard customized gears, we also need to consider their transmission efficiency. The transmission efficiency depends on the tooth shape and number of teeth of the gear. When purchasing, we should ensure that the design of the gear can achieve high transmission efficiency to improve the overall working efficiency of the mechanical equipment.


5. Check the experience of process engineers
Non-standard gear customization requires experienced process engineers to complete. They can design and manufacture gears according to specific usage requirements and working environment. Therefore, before purchasing, we should understand the supplier’s process engineer team, understand their experience and strength, to ensure the quality and performance of the product.
6. Confirm after-sales service
We also need to carefully consider the supplier’s after-sales service. Gears are important components in mechanical equipment. If there are quality problems or other failures, after-sales service will play a vital role. When purchasing, we should choose suppliers who provide comprehensive after-sales service to obtain timely repairs and support.
Through the above 6 precautions, we can more accurately choose non-standard gear customized products that meet our needs. Be cautious when choosing suppliers and conduct multiple inspections to ensure that you purchase high-quality products and services. I hope this article is helpful to you. Thank you for reading!
