Pump bearing combined load testing fixture

Abstract

The present invention discloses a pump bearing combined load testing fixture. The testing fixture comprises a detection mechanism and a loading mechanism. The detection mechanism comprises a fixing component disposed on an outer side of a to-be-measured pump bearing and a driving part that drives the to-be-measured pump bearing to rotate. The fixing component comprises a fixing sleeve sleeved on the outer side of the to-be-measured pump bearing. The loading mechanism is disposed at an end of the to-be-measured pump bearing that is far away from the driving part. The loading mechanism comprisesa loading shaft fixed on a core shaft of the to-be-measured pump bearing and a loading component sleeved on the loading shaft. The loading component comprises a radial loading component and an axialloading component. The fixing sleeve facilitates to fix the whole testing fixture on a certain fixing mechanism, so that the testing fixture stably runs. During test, the radial loading component andthe axial loading component are used for simulating an actual working condition, a combined load is applied to the core shaft of the to-be-measured pump bearing, and the driving shaft is driven by a motor, to drive the core shaft to rotate, so as to test life durability performance of the to-be-measured pump bearing in the working condition.

Description

technical field [0001] The invention belongs to the technical field of bearing detection, and in particular relates to a shaft-connected bearing combined load test tooling. Background technique [0002] Shaft-connected bearings are a kind of bearings. Shaft-connected bearings are generally used in machinery such as water pumps and fans. When such machines are in operation, shaft-connected bearings often bear combined axial and radial loads. Multi-channel performance test. When testing the load capacity of the existing bearings, they often only test the operation of the bearing when it bears a one-way load, which is different from the actual operation and cannot meet the actual use requirements. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a test tool that can simulate the actual working condition of the shaft-connected bearing and test the life and durability of the shaft-connected bearing under t...
