Title:
ROLLING BEARING UNIT FOR RAIL VEHICLE
Document Type and Number:
Japanese Patent JP2010096207
Kind Code:
A
Abstract:
To prevent a rolling bearing for a rail vehicle from causing electrolytic corrosion without using a ground brush and also without changing the components of the bearing.
A rolling bearing unit for the rail vehicle is adjacently disposed with a bearing 10 for a vehicle and an electrifying rolling bearing 30 in a shaft direction, and makes the electrification property of the lubricant of the electrifying rolling bearing 30 higher than that of the lubricant of the bearing for the vehicle 10. Thus, a current only flows through the electrifying rolling bearing 30, thereby avoiding a current which is intended to flow through the bearing for the vehicle 10.
