Experimental method and equipment of medium and small swing bearings with heavy loads

Abstract

The invention discloses an experimental method of medium and small swing bearings with heavy loads. The experimental method comprises the steps that a swing oil cylinder drives an experimental main shaft to make an experimental bearing to swing periodically, loads are applied to the experimental bearing in a hydraulic servo loading mode, the dynamic and static experiment loads are provided for theexperimental bearing so that the experimental bearing can be tested according to the required loads, a weighing sensor is used for detecting whether or not the pressure applied by a hydraulic systemis identical to a target set value, and thus the whole loading system can form loop control. The experimental method is mainly used for various performance tests of the various newly developed heavy-load medium and small swing bearings with heavy loads, related experimental requirements, put forward in the bearing development process, for bearing capacity are met, the purposes of large swing angle, high frequency and heavy loads are achieved, and the experimental requirements of the medium and small swing bearings with heavy loads are met. Not only radial loading experiments of the medium andsmall swing bearings with heavy loads but also related experiments such as high-frequency, periodical and large-angle swing experiments and durability experiments of the experimental bearing can be completed.

Description

technical field [0001] The invention belongs to the technical field of bearing testing, and mainly relates to a testing method and equipment for testing heavy-duty medium and small oscillating bearings. Background technique [0002] At present, in the real-time speed test of the bearing, in addition to the load on the general bearing, the oscillating bearing does not run in the same direction for a long time or intermittently forward and reverse like the general bearing, but in a certain angle range There is a regular fast swing operation. The traditional test requires recording the real-time speed of the test bearing, which can be read through the speed sensor or monitoring the frequency of the motor, while the swing bearing performs swing motion at a certain frequency, not only to realize the input of the swing frequency and swing angle, but also to realize the swing Data reading of frequency and swing angle, because the motor cannot achieve high-frequency forward and rev...

AI Technical Summary

Problems solved by technology

At present, there is very little research in the field of test methods for heavy-duty small and medium-sized oscillating bearings in my country, and the number of literature and patents in related fields that can be found is very limited. However, in actual working conditions, we need to design and study such test methods to verify The performance of small oscillating bearings, so it is urgent to develop related bearing test methods
