Nice Bearing Kit

It is expected that, with policy support, by 2015, the sales of China's bearing industry will reach 222 billion yuan, and the industry’s average annual growth rate will be 12 Between %-15%.At present, only a few companies in China, such as Axion Research Technology, can mass produce this grade of products, and there is huge room for substitution in the future market. According to one spindle per machine tool, the domestic market capacity of ultra-precision bearings of P4 and above is about 250,000 sets.　　

At present, the only domestic manufacturers that can mass produce the electric spindle of CNC machine tools are only a few companies such as Axis Research Technology, and most of them need to be imported. It is expected that domestic bearing companies with advanced technology and high-end products will enjoy the results of high-end bearing import substitution.

According to the plan, the sales of the bearing industry will reach 222 billion yuan by 2015, with a CAGR of 13. The '2012-2015 China Bearing Manufacturing Industry Production and Sales Demand Forecast and Transformation and Upgrading Analysis Report' released by the Foresight Industry Research Institute shows that the process of industrialization and urbanization has brought about the sales of related Clutch Release Bearing factory industries such as automobiles, construction machinery, electrical appliances, and machine tools in recent years.

A high-end submarket with large room for import substitution. From the perspective of the 'Twelfth Five-Year Plan' of the bearing industry, the autonomy rate of bearings in key areas has doubled room for improvement, and the space for import substitution is relatively broad.

The bearing manufacturing research team of the Qianzhan Industry Research Institute has focused on analyzing the operating conditions and development plans of leading enterprises in the bearing industry and learned that the products of this type of company are mainly positioned in 'high, precise, cutting-edge, special, and specialized', and mostly focus on technical barriers.

At this time, if the bearing is rotated in oil, be careful that the rolling surface may be damaged by foreign objects. After cleaning, immediately apply anti-rust oil or anti-rust grease on the imported bearings. In addition, confirm the amount of remaining lubricant and sample the lubricant before cleaning the bearing. During rough washing, use a brush to remove grease or adhesions in oil. 　　

The correct cleaning method of solid ring bearings: No matter which cleaning agent is used, it must be filtered frequently to keep it clean. 　　 So how to clean it? Today, the editor of the physical ring bearing introduces its cleaning method.

The above is the cleaning method of the solid ring bearing.As long as you clean it according to the above method, it will definitely prolong the service life of the solid ring bearing and improve your work efficiency.. When fine washing, slowly rotate the bearing in oil, and it must be done carefully. 　　

If the bearing is used for a long time, in order to ensure the normal operation of the bearing, it must be cleaned effectively before it can be used better. The bearing cleaning is divided into rough washing and fine washing, and a metal grid can be placed on the bottom of the Clutch Release Bearings container.

When removing the imported bearings for inspection, first make a record of the appearance with photography and other methods. The commonly used cleaning agent is neutral non-water-containing diesel or kerosene, and sometimes warm lye is used as needed

Represents the number of times that the friction torque of the set of bearings is greater than that of other bearings. This method can effectively solve the effect of different numerical sequence on the friction torque of rolling bearings. 3.1. The larger the value, the worse the lubrication and operational flexibility of the set of bearings compared with other bearings.

This method synthesizes the overall situation of the two sets of bearing friction torque to judge the timing characteristics of the bearing friction torque, which can avoid the influence of individual larger or smaller data in the data, can reflect the specific comparison of the rolling bearing friction torque, and then characterize the timing characteristics of the rolling bearing friction torque .

Obviously, the two comprehensively reflect the sensitive performance and stability of bearing friction torque, which lays the foundation for the preliminary analysis of bearing friction torque. A small value of s and a larger value indicate The bearing has good sensitivity performance but unstable performance; A.05. Finally, the results of the above three methods are summarized to comprehensively judge the characteristics of the friction torque of rolling bearings, and the bearing with the best performance is selected from a few sets of rolling bearings.

The higher the rank sum R(X) value, the lower the order of the friction torque of the set of bearings, the worse the state characteristics, that is, the poor friction performance of the bearing.01 and 0. C is the standard value under the significance level a in the specific sample space, which represents a benchmark value, and greater than this value indicates that the level of difference has reached a certain degree. 4. Judgment method of the basic characteristics of rolling bearings The basic characteristics of rolling bearings are reflected by the sensitivity coefficient 4 and the stability performance coefficient S.

The smaller the value, the greater the difference in comparison results, and the larger the value, the smaller the difference in comparison results. The smaller the value, the better the sensitivity of the bearing; s, the smaller the value, the better the stability of the bearing: a large value of 4 and a small value of Si indicate poor sensitivity of the bearing but stable performance. Rolling bearing state feature evaluation method The rolling bearing state feature evaluation method adopts the rank sum evaluation method.

Generally, the significance level a takes the values ​​0. Evaluation method of rolling bearing timing characteristics Clutch Release Bearing In the evaluation of rolling bearing timing characteristics, the significance level a is a state parameter that measures the level of friction torque of rolling bearings. 2. For general equipment, the confidence level of friction torque is 95%; for important equipment, the confidence level of friction torque is 99%~100%.. and s, both large values ​​indicate that the bearing has poor sensitivity performance and unstable performance
