Description

Technical Field

[0001] The present invention relates to the technical field of reducers, and more specifically to a test fixture for reducers. Background Art

[0002] As an important component of mechanical equipment, reducer is widely used in many fields such as robots, automobiles, and construction machinery. Its core function is to increase the output torque by reducing the speed, thereby improving the torque output ratio of the equipment. The test fixture is a key equipment in the reducer testing process. It undertakes the important tasks of simulating actual working conditions and accurately measuring various performance parameters.

[0003] During the test process of existing test fixtures, the reducer will generate certain vibrations when running at high speed or bearing loads. However, the existing test fixtures often lack effective shock absorption and fixing mechanisms, resulting in the inability to effectively control the vibrations, thereby affecting the accuracy and reliability of the test data. This instability may not only lead to deviations in the test results, but may also cause damage to the test fixture itself, increasing the test cost and risk. The clamping device in the existing test fixture lacks sufficient clamping force and stability. During the test process, the clamping device may not be able to effectively clamp the reducer, causing the reducer to shake or fall off, affecting the accuracy of the test results, and may also cause safety hazards to the testers.

The mounting hole 302 at the bottom allows the bolt 305 to pass through to fix the box 301 and the reducer on the fixing device 7. The fixing block 701, the connecting rod 703, the moving gear 704 and the chain 705 connected at the bottom of the bolt 305 constitute a flexible fixing system.
