Description

A reducer flip test machine

technical field

The invention relates to the technical field of reducer test machine tooling, in particular to a reducer overturn test machine platform.

Background technique

The reducer must be tested before leaving the factory to ensure that each reducer is qualified. In order to solve this problem, large enterprises at home and abroad generally introduce expensive advanced test equipment. The equipment is suitable for mass production, while the test machine is efficient and environmentally friendly, but it is not suitable for small and medium batch production and the majority of small and medium-sized enterprises.

Domestic small and medium-sized enterprises are unable to introduce advanced testing equipment due to limited funds. They can only manually fix each reducer on a simple testing machine for testing. This testing method not only requires more than two workers to operate, The efficiency of the test machine is low, and it is easy to cause safety accidents. At the same time, during the test run, and when adding and discharging oil into the reducer before and after the test run, it is easy to leak lubricating oil and cause environmental pollution. Although this test machine method can meet the needs of small-scale production, it cannot meet the actual use needs of enterprises in mass production in terms of test machine efficiency, energy saving, environmental protection, and cost performance.

For this reason, there is an urgent need to develop a low-cost reducer test machine, improve test machine efficiency and energy-saving and environmental protection performance, and at the same time, be suitable for small and medium-sized batch production and the needs of the majority of small and medium-sized enterprises.
