Introduction to flexible bearings:
The flexible rolling bearing uses the controllable elastic deformation of the flexible element to transmit motion and power, large transmission ratio and wide range of application, high precision, small air return, bearing capacity, high efficiency, small size, light weight, stable transmission, low noise, can transfer movement to the sealed space.
Harmonic reducer by rigid wheel, flexible wheel, and harmonic generator three, one is indispensable.
Harmonic reducer is usually used in robot, machine tool, aerospace and other industries, the harmonic accelerator precision, rigidity and bearing capacity of the requirements are very high, so the harmonic reducer internal parts of the processing precision and installation precision requirements are very high, the same requirements for bearings are very high. For rigid bearings, the most important thing is the rigidity, reliability and rotation accuracy of bearings. Rigid bearings will be preloaded to a certain extent before leaving the factory to ensure sufficient rigidity of bearings. The most important thing for flexible bearings is the maximum radial deformation of bearings.
Harmonic reducer bearings include rigid bearings and flexible bearings two types, rigid bearings contain four kinds of series, CSG (CSF) series, SHG (SHF) series, CSD series, SHD series, the naming of the reducer; Flexible bearing is named HYR.
CSG (CSF) series
The outer ring is divided into two pieces, and the inner ring is a whole structure. Flange and bearing seat are not required for installation. It is mainly used in the output parts of CSG (CSF) series reducer.
SHG (SHF) series
The outer ring and the inner ring are integral structure, which has almost no impact on the performance during installation, and can obtain stable rotation accuracy and torque. It is mainly used in the output parts of various kinds of retarders of SHG and SHF series.
CSD series
The outer ring and inner ring are integral structure, the outer diameter size and CSG type are the same, more rigid than CSG type bearing, mainly used in CSD series deceleration output parts.
SHD series
Outer ring and inner ring are integral structure, inner ring with teeth, can directly mesh with the teeth on the flexwheel, lower height than SHG, saving the installation space of the reducer, mainly used in the output part of SHD reducer.
