Abstract

The invention discloses a motor decelerator test system. The motor decelerator test system comprises a tested motor decelerator, a loading motor decelerator, a first oil circuit, a second oil circuit, a third oil circuit, a fourth oil circuit and a first overflow valve, wherein a power shaft of the loading motor decelerator is connected with a power shaft of the tested motor decelerator in transmission mode, the first oil circuit is used as an oil inlet passage of the tested motor decelerator, the second oil circuit is used as an oil return passage of the tested motor decelerator, the third oil circuit is used as an oil recharging and feeding passage of the loading motor decelerator, the fourth oil circuit is used as an oil recharging and feeding passage of the loading motor decelerator and connected with the first oil circuit, and the first overflow valve is connected onto the third oil circuit and used to maintain pressure and flow rate of the third oil circuit. According to the motor decelerator test system, energy recovery efficiency of the system can be improved, and energy loss can be reduced. Furthermore, the motor decelerator test system facilitates increasing stability of running of the tested motor decelerator, and therefore can meet the needs of various tests.

Description

technical field [0001] The invention relates to the field of motor reducer testing, in particular to a motor reducer testing system. Background technique [0002] The motor reducer is the executive element in the hydraulic transmission system and the core component of the hydraulic transmission. It is widely used in various fields such as machinery, machine tools, ships, military, aerospace, petroleum, etc. Its performance directly affects and determines the hydraulic system and the whole machine. Therefore, the test of the performance characteristics of the motor reducer is very important. [0003] At present, the test of motor reducer can be divided into two kinds of loading test systems: direct loading and power recovery from the energy recovery or not. The direct loading system has simple structure, convenient and accurate loading, and little interference, but it consumes a lot of energy and is not suitable for high-power test, long-term life test and high-volume hydrau...

AI Technical Summary

Problems solved by technology

Among them, the electrical power recovery method requires the addition of electrical components such as rectification or inverter systems. The technology is complex, expensive, and the recovery efficiency is not high, so it is not the preferred solution of relevant manufacturers; while the hydraulic power recovery method has the advantage of a higher power recovery rate. And the cost is relatively low

[0005] However, in the existing technology, the hydraulic power recovery method has shortcomings such as unstable test speed (especially in low-speed environments), incomplete test functions, etc., and it is difficult to meet the test of motor reducers, especially those used for walking and hoisting. need
