Abstract

The invention relates to testing platforms, in particular to a comprehensive performance testing platform for a planetary roller screw, and aims to solve the problem that currently a comprehensive performance testing platforms for the planetary roller screw does not exist in China. The comprehensive performance testing platform comprises a cast iron platform, an alternating-current servo motor, a planetary reducer, an elastic coupler, a torque sensor, a rotation encoder, a linear guide rail, a movable platform, three bearing columns, a pull pressure sensor and a hydraulic cylinder, wherein the alternating-current servo motor, the planetary reducer, the elastic coupler, the torque sensor, the rotation encoder, the movable platform, the pull pressure sensor and the hydraulic cylinder are sequentially arranged on the upper surface of the cast iron platform from left to right, the alternating-current servo motor is connected with the planetary reducer, and the planetary reducer is connected with the torque sensor through the elastic coupler. The comprehensive performance testing platform belongs to the field of mechanical performance testing.

Description

technical field [0001] The invention relates to a testing platform, in particular to a comprehensive performance testing platform of a planetary roller screw, which belongs to the field of mechanical performance testing. Background technique [0002] The planetary roller screw originated in the early 1840s, but was not widely used due to its complex structure and backward manufacturing technology at that time. With the development of aircraft and weaponry and the need for high-thrust, high-frequency, and long-life mechanical devices, traditional linear motion unit arms such as roller screws and trapezoidal screws are increasingly unable to meet the above requirements. So far, planetary Roller screws are only beginning to be extensively studied. [0003] Although the planetary roller screw has many advantages and good development prospects, as far as the country is concerned, the development of test experiments is not enough to verify the design theory, which greatly limits ...
