Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a seismic resistant base of a precision bearing dynamic friction torque tester. Background Art

[0002] Bearings may seem simple, but they are the most widely used basic and key parts in various rotating equipment and mechanisms. According to historical statistics, more than 80% of the failures of moving parts and mechanisms are caused by bearing failures. Especially in some special occasions (such as space environment, continuously running production lines), bearings cannot be backed up, so once a bearing fails, it will affect the whole, and the consequences will be catastrophic. In the past two decades, due to the problem of bearings, personnel at all levels have paid more and more attention to this. With the increasing requirements for the effectiveness of bearing quality control and performance evaluation, higher requirements have also been put forward for the previous evaluation indicators and means.

[0003] For a long time, domestic bearing testing has been based on the static indicators of bearings and their components (inner and outer rings and balls) (such as size tolerance, shape tolerance, position tolerance and fit clearance between components, etc.) to evaluate bearings. However, static indicators cannot reflect the status under various operating conditions. Users need more dynamic indicators to understand the status of bearings during use and testing and make correct judgments.

[0004] The most basic, main and quantifiable indicator of bearing dynamic performance is friction torque, which reflects the power consumption and performance of bearing. The movement of bearing is a very complex process, which is mainly based on actual tests. First, the friction torque of single bearing is tested. Single bearing is the most basic single part. Only by starting with the most basic control can the use of bearing be effectively controlled.

[0005] However, after the bearings are produced, various data of the bearings need to be tested. Although the detection equipment runs slowly, the operation of the equipment always brings certain vibrations, resulting in insufficient detection accuracy of the equipment. Therefore, an improved technology is urgently needed to solve this problem existing in the prior art. Utility Model Content
