Adjusting structure of pulley
It is convenient to adjust the axial clearance of the pulley bearing.
The threaded ring shall be provided with anti loosening measures, which is suitable for high rotation.
High speed and large axial load.
Simple structure, convenient disassembly and assembly, axial.
elastic
Small size, suitable for low rotating speed and shaft.
Retaining ring
When the axial load is small, the adjusting ring between the circlip and the bearing can adjust the axial compensation of the shaft.
Bearing configuration
A shaft often needs two fulcrums, that is, two sets of rolling bearings for support. The bearing configuration just solves the problems of how the bearing on the fulcrum can fix the shafting axially and how to avoid jamming after thermal expansion. Let's explain the relevant knowledge of bearing configuration.
Before configuration, be sure to understand some key points related to bearings:
① Expansion and contraction of shaft caused by temperature change.
② Bearing installation and disassembly are difficult and easy.
③ Inclination of inner ring and outer ring caused by shaft deflection and installation error.
④ Preloading method of the whole rotating system pulley including bearings.
⑤ Bear and transfer the load at a suitable position.
