Abstract

The invention discloses an on-machine detection device of the worm gear pair transmission precision. The detection device comprises a rotary table for installing a worm gear and a tool for installing a worm, a worm gear angular displacement sensor which detects the rotation angle of the worm gear is installed in the rotary table, a worm angular displacement sensor which detects the rotation angle of the worm is installed on the tool, the worm gear angular displacement sensor and the worm angular displacement sensor are in output connection with a worm gear detector, the tool is provided with a bracket, a sliding plate located above the bracket and a pair of fixed centers for supporting the two ends of the worm, a driving motor is arranged on the bracket and drives a gear transmission set, and a rotor of the worm angular displacement sensor and a tail end gear coaxially and synchronously rotate to measure the rotation angel of the worm; the rotary table comprises an installation table and a base which can rotate relatively, a rotor of the worm gear angular displacement sensor is coaxially installed on a protruding column of the installation table, and a stator of the worm gear angular displacement sensor is fixedly connected with the base. The invention further discloses an on-machine detection method of the worm gear pair transmission precision. By means of the on-machine detection device and detection method of the worm gear pair transmission precision, the on-machine detection problem of the worm gear pair transmission precision is solved.

Description

technical field [0001] The invention relates to the field of detection of worm gear pairs, in particular to a clinical detection device and detection method for transmission precision of worm gear pairs. Background technique [0002] The current general procedure for worm gear pair processing is: process the worm gear on the worm gear processing machine tool (hobbing machine), process the worm gear on the worm grinder, and then match the worm gear and the worm gear on the special worm gear inspector to grind the contact surface, and test the transmission accuracy and pitch difference etc. Such as CN102435432A disclosed worm gear meshing instrument, which utilizes a second-hand gear hobbing machine to realize the worm gear and worm gear meshing instrument for detecting the meshing condition of a large worm wheel and a worm screw. It includes a second-hand gear hobbing machine, and the worm tooling is installed on the large flange of the second-hand gear hobbing machine. and ...
