In a bearing structure equipped with an oil drain runner attached to a rotating shaft and discharging waste grease by centrifugal force caused by the rotation of the rotating shaft, the rolling bearing is located between the rolling bearing and the oil drain runner, or between the bearing and the oil drain runner. In the gap,
The outer diameter is the same as the outer diameter of the rolling bearing, and a ring-shaped spacer is provided so that the inner diameter on the rolling bearing side roughly matches the inner diameter of the outer ring of the rolling bearing , and the inner diameter on the opposite oil drain runner side is smaller than this. A bearing structure for a rotating electric machine characterized by the following.

Claims

[Scope of utility model registration request]

A rolling bearing that supports the rotating shaft, a bracket that holds this rolling bearing, an axle box cover that prevents leakage of the grease that lubricates this rolling bearing,
In a bearing structure equipped with an oil drain runner attached to a rotating shaft and discharging waste grease by centrifugal force caused by the rotation of the rotating shaft, an outer diameter dimension is specified at an intermediate outer diameter portion between the rolling bearing and the oil drain runner. A bearing for a rotating electrical machine, characterized in that it is provided with a spacer whose inner diameter on the rolling bearing side is made to roughly match the inner diameter of the outer ring of the rolling bearing, and whose inner diameter on the opposite side, on the oil drain runner side, is smaller than this. structure.
