The invention provides a device and a method for measuring a raceway of a one-way overrunning clutch directional sleeve and belongs to the technical field of measurement. The invention solves the problem of low measurement accuracy of existing one-way sleeve raceway size measuring method and measuring instrument. The device for measuring the raceway of the one-way overrunning clutch directional sleeve comprises a working table with a columnar positioning core and a base; the base is provided with a datum rod in parallel to the axis of the positioning core and the datum rod is positioned at one side of the positioning core; the base is also provided with a feeding mechanism capable of driving the datum rod to horizontally move and a rod-shaped measuring bar; the axis of the measuring bar is in parallel to the axis of the positioning core and the lower end of the measuring bar is connected with a first guide rod capable of axially moving; the working table is also provided with a measuring meter; and a measuring head of the measuring meter is abutted against the rear end of the first guide rod. The method for measuring the raceway of the one-way overrunning clutch directional sleeve comprises the following steps: A, installing a workpiece; B, determining the datum; and C, carrying out measurement. The device and the method for measuring the raceway of the one-way overrunning clutch directional sleeve have higher accuracy.
Description
technical field [0001] The invention belongs to the technical field of measurement, and relates to a device and method for measuring the raceway of an directional sleeve, in particular to a device and method for measuring the raceway of the directional sleeve of a one-way overrunning clutch. Background technique [0002] The starter motor one-way overrunning clutch, its function is to transmit the output torque of the starter motor to the ring gear of the engine, and drive the ring gear to rotate. slipping in the opposite direction to protect the starter motor, and finally exit the engagement. The size of the raceway (eccentric arc) of the directional sleeve of the one-way overrunning clutch determines the ability to transmit torque. If the raceway is too large, the gear and the roller contact the outer circle to produce sliding friction, which will generate high temperature under high-speed operation, causing the spring to lose its elasticity. , the two-way slip of the one...
