1.Structure of  Rigid bearing for harmonic drive


Rigid bearing for harmonic drive is cross roller structure.According to its application area there are four types(CSF/CSG Series  and SHF/SHG Series ).Rolling body are cylindrical rollers which arranged orthogonality,this structure can make one bearing can bear the load from every direction e.g. radial,axial and tilting torque etc. Bearing with high rigidity,rotation accurancy and load carrying capacity. This series bearing has compact appearance,with mounting hole,customer can mount directly,suitable for every kinds of harmonic drives.

The rigidity,reliability and rotating accuracy are very important for the rigid bearing,so the bearing will be adjusted the preloading before leave factory to ensure the rigidity of the bearing.

Type

1.CSG(CSF) Type(Separable outer ring,integrated inner ring)

2.SHG(SHF) Type(Integrated inner and outer ring)

3.SHD Type(Integrated inner and outer ring)

4.CSD Type(Integrated inner and outer ring)

 

 

2.Application

Harmonic driver are mainly used in roboter,machine tool and aerospace etc.

 

 

3.Bearing lubrication

The rigid bearing for harmonic drive have been filled with high quality compound lithium grease before leave the factory, in normal operation condition, no need to plus grease during using.The fraction torque will be temporarily increase after plus the grease, and the fraction torque will be stable  when the grease homogeneously attached to the roller race and rollers.

The grease of harmonic drive bearing we used are FAG Arcanol Multitop, this grease have long working life, well running perfomence and high reliability , which are widely used in all kind rotate speed and temperature condition with high load, and low noise.


4.Installation Note

1. Clean the dirt and inclusion of the bearing seat and shaft which match up with bearing before assembly, and ensure there is no burr and sharp edge.(ensure the fit tolerance of the inner and outer ring,shaft journal and inner bearing conform to requirments )

2. When tightening the screw, there are 3~4 steps from partrial locking to totally locking of fixed bolt,accroding to the methed of decussation to tighten repeatly.

3. The preload have been adjusted  by our prefessional assembly worker before leave the factory, and the grease aslo have been filled.Please don’t remove the bearing or clean the bearing before installation. If receiveing the abnomal operation of the bearing after installation,please contact with us asap.

4. The operation temperature of the bearing are -20°C~~ +80°C,If the bearing work condition exceed this range,please contact with us asap

5. The material of the components which match to bearings can choose alluminium alloy or cast iron.

6. If the bearing dimension which you used can not find in our enclosed table or the dimension is different, please contact with us.
