Harmonic reducer is made up of rigid wheel, flexible wheel and harmonic generator(HONBbearing06).
Harmonic reducer is usually used in robotics, machine tools, aerospace and other industries, harmonic accelerator precision, rigidity and bearing capacity and other requirements are very high, so the processing accuracy and installation accuracy of each part of the harmonic reducer are very high, the same to the bearing requirements are very high.
For the rigid bearing, the most important thing is the rigidity, reliability and rotation accuracy of the bearing. Before the rigid bearing leaves the factory, the bearing will be adjusted to a certain pre-pressure to ensure that the bearing is sufficiently rigid.The most important thing for flexible bearings is the maximum radial deformation of the bearing.
Harmonic reducer bearings include rigid bearings and flexible bearings, rigid bearings include four series, CSG (CSF) series, SHG (SHF) series, CSD series, SHD series, the name of the reducer is named;The flexible bearing is named HYR.
The outer ring is divided into two pieces, and the inner ring is a whole structure. Flange and bearing pedestal are not needed during installation. It is mainly used in the output part of various reducer of CSG (CSF) series.
The outer ring and the inner ring are of integral structure, which have little influence on the performance during installation, and can obtain stable rotation accuracy and torque, which are mainly used in the output parts of various reducer of SHG and SHF series.
The outer ring and inner ring are of integral structure, the outer diameter size is the same as that of CSG type, and more rigid than THAT of CSG type bearing, mainly used in the OUTPUT part of CSD series deceleration.
The outer ring and the inner ring are of integral structure, and the inner ring has teeth, which can directly engage with the teeth on the flexible wheel, and the height is lower than that of SHG, saving the installation space of reducer, mainly used in the output part of SHD reducer.
