摘要：PURPOSE:To effectively prevent lubricating oil from flowing out from the bearing of a rotary electric machine along its shaft by mounting an axial flow preventive insulating ring via slight gap on the shaft. CONSTITUTION:Oil aling rings 6 are mounted via bolts 15 at a bracket filled with lubricating oil, and an insulating ring 14 is provided integrally formed by welding to the inner periphery of the ring 6. The ring 14 is formed in gap a with the shaft 1. Thus, the oil surrounded by the bracket 3 may not be externally leaked via the gap a between the ring 14 and the shaft 1. Since the ring 14 further effectively shuts off the circulating current, it can commonly effect the oil aling and shaft current preventive effects so as to thereby simplify the mechanism.
