Abstract

The invention discloses speed reducer testing equipment. The speed reducer testing equipment comprises a support platform, and a servo spindle motor, a first rotation speed and torque sensor, a second rotation speed and torque sensor, a transmission and a brake which are arranged on the support platform, wherein an output shaft of the servo spindle motor is connected with an input shaft of a speed reducer to be tested through the first rotation speed and torque sensor; an output shaft of the speed reducer to be tested is connected with an input shaft of the transmission through the second rotation speed and torque sensor; an output shaft of the transmission is connected with the brake; the first rotation speed and torque sensor is used for detecting input rotation speed and/or input torque; the second rotation speed and torque sensor is used for detecting output rotation speed and/or output torque of the speed reducer to be tested; the transmission and the brake are matched to provide a load for the speed reducer to be tested. Due to the adoption of the mode, according to the speed reducer testing equipment, the transmission and the brake are matched to provide the load, the load provided by the brake is exponentially amplified by the transmission, so that a large-size brake is not needed even through a large load is needed during testing, and thus the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a speed reducer testing equipment. Background technique [0002] With the development of science and technology, construction machinery has gradually increased the comprehensive performance requirements of the reducer. High-precision cycloid reducer, RV reducer, harmonic reducer, etc. are all high-precision transmission components that have grown under this background. They are used in robots, instruments, medical equipment, aerospace and high-precision machine tools, etc. fields are widely used. In order to ensure the performance of the reducer, accurate, convenient and efficient testing equipment is essential. However, in the existing reducer testing equipment, the brake is generally used to provide the load for the reducer. Therefore, when the reducer requires a large load, a large brake is required to provide the load. Large brakes are expensive, making the ...
