Bearing friction torque measuring instrument

Abstract

The utility model provides a bearing friction torque measuring instrument, relates to the technical field of measuring devices, and aims to solve the problems that a conventional bearing friction torque measuring instrument lacks a structure for assisting in adding lubricating oil, and the lubricating oil needs to be added into a bearing manually during detection, so that the labor capacity of workers is increased. The mounting mechanism comprises a main body, a mounting frame and a fixing hole, and a circular table-shaped structure is arranged at the upper end of the main body; and the mounting frame is fixedly mounted at the upper end of the main body. When the fixing part drives the inner end of the bearing to extend into the bearing part, the baffle ring limits the conduction part, and along with continuous descending of the fixing part, a round hole transversely formed in the conduction part can be communicated with a leakage hole, so that lubricating oil in a storage groove enters a communicating groove through the leakage hole and flows out through a round hole vertically formed in the bottom of the communicating groove, and the lubricating oil is stored in the storage groove. Therefore, automatic lubrication of the bearing is realized, and lubricating oil does not need to be manually added into the measured bearing.

Description

Technical Field

[0002] Bearings are an essential component in modern machinery. Before being put into use, bearings need to have their performance tested. Friction torque parameters have a significant impact on the use of bearings, and the accuracy of friction torque measurement directly determines whether there are any abnormalities in the bearing. Therefore, after the bearings are manufactured, they all need to be tested for friction torque using a measuring instrument.

[0003] Based on existing technology, it has been found that existing bearing friction torque measuring instruments have some shortcomings. First, the structure for fixing the bearing in the friction torque measuring instrument is usually fixed by bolts. When measuring different types of bearings, it is necessary to remove the bolts to replace the fixing structure, which is very troublesome. Second, the bearing friction torque measuring instrument lacks a structure for adding lubricating oil. During testing, lubricating oil needs to be added manually to the inside of the bearing, which increases the workload of the staff. Utility Model Content
