What is Harmonic Reducer?
Date: 2019-03-07 17:36
Harmonic Reducer is mainly composed of harmonic generator, flexspline, rigid spline, and also rigid bearing (cross roller bearing) and flexible bearing (thin section deep groove ball bearing).
Flexible bearing’s inner hole match with oval shaped cam outer ring; outer ring which can do elastic-deformation to match with flexspline’s opening part inner ring. Flexspline’s opening part outer ring engraved gear engaged with rigid spline teeth. Rigid spline teeth are more than flexspline. Flexspline and rigid spline engaged with each other on long shaft and separated on short shaft. Flexspline bottom is fixed on the output terminal. Rigid bearing (cross roller bearing) is installed on the reducer output terminal and connected with outside.
Harmonic Reducer is usually applied on robots, machine tool, and aerospace industries which have high requirements on harmonic reducer precision, rigidity, and load capacity. So it has high requirements to harmonic reducer parts machining precision and mounting precision and also to bearings. For rigid bearing (cross roller bearing), the most important are the bearing rigidity, reliability, and rotation precision. Rigid bearing (cross roller bearing) usually has some preload before leaving the factory in order to guarantee bearing has enough rigidity. The maximum radial deformation is very important to flexible bearing.
We Hubei Parts Service Supply Co., Ltd offering flexible bearings, rigid bearings (cross roller bearings), harmonic reducer bearings, RV reducer main bearings and crank bearings with very high precision for years. We have accumulated rich experience, absolutely solved the problem of bearing quality stability. Our bearings are supplied to lots of the robots reducer manufacturers over the world.
