A kind of device for detecting durability of harmonic reducer flexible wheel of the invention, can specifically for flexbile gear endurance quality into
Row detection, at the same by the quick connection type of motor output shaft and flexbile gear inner wall convenient for it is quick, be replaced as frequently as it is to be detected soft
Wheel, and with output shaft and the harmonic wave axis and bearing of top wheel substitution harmonic speed reducer, testing cost is reduced, harmonic reduction is eliminated
The possible disturbing factor of device other structures, being can a kind of comparison that is frequent, multiple and carrying out flexbile gear durability test for a long time
The device for detecting durability of creative harmonic reducer flexible wheel.
A kind of device for detecting durability of harmonic reducer flexible wheel of the invention is coaxially limited defeated by motor shaft limited block
Shaft, coaxially limits slow-speed shaft by slow-speed shaft limited block, provides rotational resistance by damper for slow-speed shaft, by fixed rigid
The firm gear of wheel model rahmonic retarder, and realize and engage connection with the groove of flexbile gear outer wall, sensor and counting are reached by pipe
Disk detects the revolution of output shaft and slow-speed shaft, guarantees the levelness of detection faces by horizontal detection plate, and be convenient for dial gauge pair
Output shaft in rotation and slow-speed shaft carry out the real-time detection of concentricity, finally by symmetrical in output shaft one end and be rotatablely installed
Top wheel model rahmonic axis and bearing, rotation extruding is carried out to the inner wall of flexbile gear, harmonic wave axis is solved and bearing is difficult to from flexbile gear
The problem of upper disassembly, and can thus exclude harmonic wave axis and bearing damage bring flexbile gear detection disturbing factor.
