Problems solved by technology

At present, when measuring the signals of various parameters during the operation of the gears in the reducer at home and abroad, due to the small internal space of the transmission device, the complex environment, the difficulty of sensor arrangement and installation, and the signal transmission is easily disturbed, there has been a lack of effective testing methods. The collection and status monitoring of the dynamic data of the transmission device brings great difficulties

Abstract

The invention discloses an intelligent gear. The intelligent gear comprises a gear body and a monitoring device, wherein gear tooth grooves and gear grooves are simultaneously formed in gear teeth and the bottom between adjacent teeth; or only the gear tooth grooves or the gear grooves can be formed, wherein the gear tooth grooves comprise two gear tooth grooves which form equal-distance curves with tooth outlines respectively, and straight-line gear tooth grooves between the tooth crest of the gear teeth and the crossed point of the two curved gear tooth grooves; the gear grooves are straight-line gear grooves arranged in tooth grooves and located in the radial direction of the gear body; the gear tooth grooves and the gear grooves are filled with elastic bodies; the monitoring device comprises a data receiving device and sensors arranged in the elastic bodies; the sensors and the data receiving device are wirelessly connected. According to the intelligent gear, parameters including torques, rotary speeds, stress, strain, accelerated speeds, temperatures and the like of the gear which reflect the working condition of the gear can be effectively monitored in real time by using a memory property and a deformation controllable property of an elastic body material and an intelligent sensing detection capability of the sensors; the technical defects in an existing transmission device that the stress and the strain of the gear cannot be monitored are overcome.

Description

technical field [0001] The present invention relates to a gear, in particular to a gear that has adaptive deformation coordination capability within the designed transmission precision range, can filter out fluctuations generated in power transmission and motion transformation, and has high precision and high reliability. gear.
