It is studied the existing three kinds of bearing arrangement for the driving gear shaft of locomotive motor.
The use of a good sealing or retaining shield is a prerequisite to prevent grease leaking from the bearing arrangement.
If matched pairs of tapered roller bearings arranged face-to-face or back-to-back are mounted together with a third bearing, the bearing arrangement is statically indeterminate.
Using CARB bearings in vibratory applications on the non-locating side of the bearing arrangement will result in a self-aligning bearing system with better performance and reliability.
