Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing testing technology, and in particular to a bearing radial vibration testing device. Background Technology
[0002] Bearings are important components in modern mechanical equipment. Their main function is to support the rotating shaft of the machine and reduce the friction coefficient of the moving parts during the rotation process. Their precision, performance, lifespan and reliability play a decisive role in the precision, performance, lifespan and reliability of the main machine.
[0003] Based on the comparison of existing technologies, radial vibration is one of the important indicators for measuring bearing quality during the manufacturing and use of bearings. Existing devices all use electromagnetic vibration tables to apply excitation signals and collect vibration data through acceleration sensors, which results in high equipment maintenance costs and requires a supporting data acquisition system, making operation complex. In addition, traditional fixtures mostly use one-way screws or hydraulic clamping, which may cause the bearing to be unbalanced, affecting the authenticity of vibration testing. Furthermore, all fixtures require operators to position and fix them, which may lead to large differences in test results when different operators fix them. Utility Model Content

[0008] According to the aforementioned bearing radial vibration testing device, the fixed plate is positioned inside the sliding groove, and the fixed plate is slidably connected to the inside of the sliding groove. Through the slidable connection between the fixed plate and the inside of the sliding groove, the fixed plate can move more stably left and right by being limited by the sliding groove.
[0009] According to the aforementioned bearing radial vibration testing device, the platform is positioned at the upper end of the base plate, and the platform is slidably connected to the upper end of the base plate. This slidable connection between the platform and the upper end of the base plate allows the platform to move more easily left and right.

Through the slidable connection between the platform and the inside of the sliding groove two, the platform can move more stably left and right by being limited by the sliding groove two when it moves.
[0011] According to the aforementioned bearing radial vibration testing device, the first rotating column is positioned inside the base plate and is rotatably connected to the interior of the base plate. This rotatable connection allows the first rotating column to rotate more stably.
[0012] According to the bearing radial vibration testing device, the clamping plate is positioned on the surface of the table, and the clamping plate is slidably connected to the surface of the table. The slidable connection between the clamping plate and the surface of the table allows the clamping plate to move more stably left and right.
[0013] According to the bearing radial vibration testing device, the fixed block is positioned on the side of the platform and is fixedly connected to the side of the platform. By fixing the fixed block to the side of the platform, the platform moves along with the fixed block when the fixed block moves.
[0014] This utility model has the following beneficial effects:
[0015] 1. Compared with the existing technology, by rotating the knob, the bidirectional threaded rod is driven to rotate. Then, through the setting of the sliding groove and the fixed plate, the two moving blocks move inward, driving the clamping plate to move as well.
