[0003] Patent CN110207983A discloses a "reliability test bench for screw guide rail reverser", and patent CN204881942U discloses a "ball screw friction torque detector". The moving screw drives the ball movement of the reverser to realize the detection, instead of directly driving the reverser to rotate, but at this stage, the detection of the friction torque of the reverser is mostly realized by manually rotating the reverser, and their The structure of the device is more complex, there are many sources of error, and it lacks certain versatility

Abstract

The invention discloses a lead screw reverser frictional resistance torque detection device, which comprises a test platform, two friction wheel mechanisms and a lead screw mechanism, wherein the twofriction wheel mechanisms and the lead screw mechanism are arranged on the test platform; the two friction wheel mechanisms are symmetrically arranged on the two sides of the lead screw mechanism. Thelead screw mechanism comprises a first support, a second support, a reverser, a reverser sleeve and a lead screw. Two ends of the lead screw are respectively supported on the first support and the second support; the reverser is matched with the lead screw; the reverser sleeve is fixedly connected with the reverser; each friction wheel mechanism comprises a third support, a fourth support, a friction wheel, a motor, a first coupler, a torque sensor and a second coupler. Two ends of a rotating shaft of the friction wheel are respectively supported on the third support and the fourth support; the friction wheel and the reverser sleeve are tightly pressed; the motor is fixed on the fourth suport; the first coupling is connected with the motor rotating shaft and the torque sensor; the secondcoupler is used for connecting the torque sensor and the friction wheel rotating shaft; the device can directly drive the reverser to rotate to detect the frictional resistance moment of the reverser.

Description

technical field [0001] The invention belongs to the field of testing lead screw reversers, in particular to a detection device for friction resistance torque of a lead screw reverser. Background technique [0002] The friction resistance torque detection device can easily measure the friction resistance torque suffered by the device, and the detection of the friction resistance torque of the reverser should tend to simulate the hand detection method, that is, the detection of the friction resistance torque can be realized by driving the reverser to rotate , and then evaluate the manufacturing quality of the inverter. [0003] Patent CN110207983A discloses a "reliability test bench for screw guide rail reverser", and patent CN204881942U discloses a "ball screw friction torque detector". The moving screw drives the ball movement of the reverser to realize the detection, instead of directly driving the reverser to rotate, but at this stage, the detection of the friction torque...
