Abstract

The invention discloses a micro-gear durability test bench, which comprises an X-Y optical precision slide table, a driving motor, a driving shaft, a driven shaft, an X-direction displacement pad and a base. The X-Y optical precision sliding table and the X-direction displacement pad are installed on the base, and the drive motor is installed on the X-Y optical precision sliding table. The driven shaft of the gear is installed above the X-direction displacement pad. By adjusting the X-Y optical precision slide table and the X-direction displacement pad, the two micro-gears are meshed, and the driving motor provides a rotating speed for testing. The test bench of the present invention has small structural size, easy assembly and disassembly, and is convenient for an optical magnifying glass to observe the meshing situation of the micro-gear pair; at the same time, the design of the micro-gear shaft and the bonding method can meet the rapid installation of micro-gears with a modulus of 0.2 mm or less. It can not only effectively guarantee the bonding strength, but also ensure a certain degree of coaxiality.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a micro gear durability test bench. Background technique [0002] Micro-gear is one of the important components of micro-reducer and micro-transmission mechanism. It has the advantages of small size, light weight, compact transmission, flexible movement, etc., and can realize movement and power transmission in a small space. At present, the main applications of micro gears are concentrated in light-load applications such as mobile wearable devices, instruments and meters, and medical equipment. With the continuous development of micro-electro-mechanical systems (MEMS), micro-gears have shown broad application potential in high-precision fields such as aerospace and biomedicine. Require. [0003] Compared with macroscopic gears, the size of microgears is usually between micron and millimeter, and its geometric feature size is too small to cause scale effect and surface eff...
