Freewheeling clutch dynamic friction torque tester

Abstract

The invention discloses a dynamic frictional force torque test set of a free wheeling clutch, and the dynamic frictional force torque test set comprises a controlling system, a testing system, and a testing device; wherein, a computer of the controlling system controls a motor of a drive mechanism through a sensor and a velometer; the motor is connected with a drive axle through a synchronous belt, the drive axle is connected with a chief axle through a clutch, the output end of the chief axle is connected with a fixed tray, an inner sleeve and an outer sleeve are arranged between the fixed tray and a relative supporting tray, and the supporting tray is fixed by a double supporting block; the tested piece is arranged between the inner sleeve and the outer sleeve and is used for three testing states: an inner frictional force torque test, an outer frictional force torque test, and a banding frictional force torque test. The complete machine has simple structure, friendly interface, and convenient operation; the invention can set the parameters such as the testing rotating speed, the sampling time, and the sampling frequency; the testing data is correct and reliable, and the testing precision is high; after being analyzed and processed by a computer software, therefore, not only the test result can be displayed in dynamic state and in visible state, but also the relative data can be analyzed and collated, and the finished testing result can be stochastically displayed, output, and archived.

Description

Technical field: [0001] The invention relates to the technical field of clutch testing, and relates to an overrunning clutch dynamic friction torque tester. Background technique: [0002] At present, the friction torque of the overrunning clutch refers to the damping torque of the relative movement of the inner and outer sleeves when the overrunning clutch is in the overrunning working state, which is mainly produced by the friction between the overrunning clutch and the inner and outer raceways. For the friction torque of the overrunning clutch, it is limited to the test of the starting torque. The test of the starting torque adopts the method of weight loading. The test process is to fix the inner sleeve and install the symmetrical force arm on the outer cover. When testing, make the force arm in a horizontal position , add a weight at the end of the force arm, when the coat is in a critical motion state, calculate and determine the value of the frictional moment through t...
