Device for testing transmission performance of speed reducers

Abstract

The invention discloses a device for testing the transmission performance of speed reducers. The device comprises a base, a test assembly and an adjusting mechanism. The test assembly at lest comprises an input end detection component and an output end detection component, the input end detection component can be connected with input ends of a corresponding tested speed reducer, and the output end detection component can be connected with output ends of the corresponding tested speed reducer; the adjusting mechanism is arranged on the base and is used for mounting the input end detection component and the output end detection component, and the relative positions of the input end detection component and the output end detection component can be adjusted by the adjusting mechanism. The device has the advantages that the device can be mounted and adjusted conveniently and quickly, is accurate in micro-adjustment and has complete test functions on the basis that requirements on the system rigidity are met; positional relations between the input end detection component and the output end detection component can be adjusted under the effects of the adjusting mechanism and can adapt to relations between input shafts and output shafts of the tested speed reducer, and accordingly the integral device can be applied to different types of speed reducers with parallel shafts, intersecting shafts, alternating shafts and the like; the device can be in flexible and changeable position adjustment modes and accordingly further can be adapted to requirements of performance tests on small and miniature speed reducers.

Description

technical field [0001] The invention relates to a transmission testing device, in particular to a transmission performance testing device of a reducer. Background technique [0002] The reducer plays the role of matching speed and transmitting torque between the prime mover and the working machine or the actuator. It is generally used for transmission equipment with low speed and high torque. The gear with a small number of teeth meshes with the large gear on the output shaft to achieve the purpose of reducing the torque increase. The transmission performance of the reducer directly affects the performance of the whole machine, so it is very necessary to carry out the transmission performance test on the reducer prototype.

[0003] There are many schemes for performance testing of reducers in the prior art: Patent CN102706557A discloses a multifunctional gear transmission test bench for measuring the static and dynamic transmission error, meshing dynamic load and load sharing coefficient of the reducer system and other performance parameters, and then analyze the influence of the parameters on the synchronization performance and load sharing performance of the gearbox; the patent application with the application number of 201310041080.0 discloses a comprehensive test device for the transmission performance of a robot gearbox. Testing of transmission performance such as box speed ratio, hysteresis, and efficiency; the application number is 201310096237.X, which discloses a hardware-in-the-loop dynamic test bench for dual-clutch automatic transmissions. It is better to test and evaluate the control strategy of dual-clutch transmission; and the transmission mechanism of the reducer not only has parallel shaft transmission mode, but also has interlaced shaft or intersecting shaft transmission mode. The experimental benches in the above schemes are all fixed settings. It can meet the performance test requirements of reducers such as direct drive shafts or parallel shafts, but the controllability of the overall system is small, and it cannot be fine-tuned according to the transmission structure type of the reducer, so it cannot meet the requirements of reducers with different shaft transmission modes. fully applicable

In addition, the above-mentioned patents and existing transmission performance test benches are all designed for large and medium-sized gearboxes. When replacing the tested gearboxes, manual installation and adjustment methods are used, which is difficult to meet the small and precise adjustment requirements of miniature gearboxes.
