Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing:

[0026] The conical friction pair used in this embodiment is the tested workpiece composed of the tested piece a3 and the tested piece b7.

[0027] Such as figure 1 As shown, the conical friction pair measurement device used in this embodiment is composed of a pressure applying mechanism, a measuring mechanism, a rotary buffer mechanism 2 and a rotary mechanism. The pressing mechanism mainly includes a pressing element 1 which moves in a linear direction and transmits power, and a servo motor driving part (not shown in the figure). The measuring mechanism mainly includes a load cell 9 and a torque sensor 8 . The pressure applying element 1, the load cell 9, the torque sensor 8 and the rotary buffer mechanism 2 are connected through a conventional connecting seat that matches with each element, and are driven by a servo motor to move up and down. The rotary mechanism inclu...

Abstract

The invention provides a method for measuring the peeling torque of a conical friction pair. According to the invention, an axial force is released and then a torque is applied so as to enable the conical friction pair to peel in allusion to separation of the conical friction pair; the rotation speed in the measuring process is controlled through a rotating mechanism; the torque is enabled to be increased more gently in the peeling process of the conical friction pair by applying a rotary buffering mechanism, the rotation speed is further adjusted according to a speed-torque curve to obtain the maximum torque value, and the measurement data is collected accurately and steadily; and the measurement data and the program execution process are displayed in real time through a display so as to enable the measuring process to be more intuitive. The measuring method provided by the invention can be widely applied to detection for the peeling torque of an automobile transmission synchronizer.

Description

technical field [0001] The invention belongs to the technical field of mechanical performance measurement, and relates to a method for measuring the performance of a conical friction pair in a conical friction clutch device in a mechanical transmission, in particular to a method for measuring the peeling torque of a conical friction pair. Background technique [0002] The main working principle of the conical friction clutch and conical friction brake in the mechanical transmission is to realize the same angular velocity of the two parts after the two relatively rotating parts are combined through the conical friction pair. Because of its simple structure, small size and large transmission torque, it is widely used in various fields of mechanical transmission, and the typical one is the synchronizer in the automobile gearbox. [0003] In order to measure the friction performance of the conical friction pair, it is necessary to detect various indicators when the friction pair...
