Rolling selection considerations cooperation

1, the bearing ring in relation to the load in relation to the load direction of rotation or swinging rings should be selected bearing for interference complexes or transition cooperation. Fixed in relation to the load direction should be selected ferrule void cooperation. When not to support activities for the separation of bearings, sliding bearings should load directions on a fixed ring as swimming rings, pick cooperation voids or transitional cooperation.

2, the type and size of the load when subjected to shock loads or heavy, generally should be selected properly, closer cooperation than at light load. About the size of the radial bearing load radial equivalent dynamic radial load PR move additional negative charge ratio CR to distinguish, the greater the load the greater cooperation interference. Load size PR / CR light load less than 0.07 0.07 normal load heavy load greater than 0.15 to 0.15.

3, bearing scale bearing the scale increases with the size, the selection of interference worked surplus bigger, the bigger the gap the void cooperation.

4, through the use of reduced bearing clearance will cause interference cooperation bearing clearance, whether the device should be checked after the bearing clearance satisfaction use request for co-operation and accurate selection of the bearing clearance.

5, the impact of the shaft and bearing information other factors, strength and thermal features; external thermal and thermal pathway occurring in the bearing and heat support means and adjustment functions and so affect the selection of cooperation.
