回転電機の回転軸の取付構造
Document Type and Number:
Japanese Patent JP4397465
Kind Code:
B2
Abstract:
The present invention provides a mounting structure of a rotary shaft of rotary electric machinery in which it is possible to cope with vibration of the rotary shaft in an axial direction with a low parts count. A fitting groove into which a portion of a rear side stopper is fitted is formed at a rear end portion of the rotary shaft. A rear side stopper has three projecting chips fitted into the fitting groove and three leaf spring chips in contact with an inner ring of a rolling bearing forming a bearing structure. The rear side stopper has a structure in which the rear side stopper generates spring force for restoring an original shape thereof when the rear side stopper is compressed in an axial direction of the rotary shaft. The rear side stopper is disposed in a compressed state between a wall face surrounding the fitting groove and the inner ring of the rolling bearing.
