Planetary bearing and gear box

Gear box is composed of an input shaft, planetary, low-speed shaft, intermediate shaft, high speed shaft.

  Planetary bearing use self aligning roller bearings and Full complement cylindrical roller bearing. In the analysis model of planetary bearings, the bearing load as  load of rolling body, fixed each gear occlusal point of internal gear end and the sun gear end , considering the outer ring deformation,to calculate bearing life.

  According to the analysis results, consider the life calculation of elastic deformation of the ring, in each column between the maximum difference of 58% generation,  we believe that the bracket end column compared with the other column end load load calculation of high proportion, short service life.

  Maximum contact surface pressure bearing gear box for the self-aligning roller bearing are calculated in the case of cylindrical roller bearing with point contact, line contact is used to obtain the. And the application considered in the calculation of non linear specification tendency.
