An elastic locking transmission mechanism for a rotating shaft

Abstract

The invention discloses an elastic locking transmission mechanism used for a rotating shaft. The elastic locking transmission mechanism used for the rotating shaft includes a motor and decelerator assembly that drives a rotating shaft system to rotate, wherein the rotating shaft system is mounted in a shaft system support; and the transmission mechanism also includes an elastic locking sleeve fixedly connected with the shaft system support, a taper sleeve fixedly mounted on an output shaft of the motor and decelerator assembly and a clutch sleeve arranged between the elastic locking sleeve and the taper sleeve, and the elastic locking sleeve, the clutch sleeve and the taper sleeve are coaxially arranged in sequence from top to bottom. The elastic locking transmission mechanism used for the rotating shaft utilizes the principle of a clutch mechanism, after the rotating shaft system is in place, the elastic locking sleeve is used to lock the shaft system, and the motor and decelerator assembly is disengaged from the rotating shaft system, the exact position of the rotating shaft system is read out under a locking condition, and a measuring error brought by micro movement of the rotating shaft system in a reading process is reduced, thereby improving measurement accuracy. After reading is completed, the elastic locking sleeve loosens the rotating shaft system, the motor and decelerator assembly and the rotating shaft system are connected, and the rotating shaft system can continue to rotate.

Description

technical field [0001] The invention relates to the field of angle measurement, including gears, screw threads, cams and orthogonal and non-orthogonal coordinate measuring machines with rotary mechanisms, in particular an elastic locking transmission mechanism for rotating shafts. Background technique [0002] Angle is a basic physical quantity, which must be measured in the measurement of gears, threads, cams, polyhedrons, etc. Orthogonal three-coordinate measuring machines are often equipped with turntables to measure various complex parts. An important direction of the development of measurement technology is to perform on-line and in-situ measurement at the processing, assembly, and work sites, and to make corrections or compensation processing according to the measurement results to prevent or reduce waste. The traditional orthogonal coordinate measurement system requires that the measured object be placed on the measuring machine for measurement, and online and in-sit...
