YBF系列隔爆型高压三相异步电动机稀油润滑滚动轴承结构研究

Structural Research on Oil-Lubricated Rolling Bearing of YBF Series High-Voltage Flame-Proof Three-Phase Induction Motors

论述了YBF系列通风机用隔爆型高压三相异步电动机传统的油脂润滑滚动轴承结构与改良后的稀油润滑滚动轴承结构的优缺点,通过对比分析,阐述出稀油润滑滚动轴承结构的优越性及可实现性,希望能够对从事隔爆型高压电机行业的设计人员起到一定的参考作用。

This paper discusses the structural advantages and disadvantages of YBF series high-voltage flameproof three-phase induction motors with traditional grease-lubricated rolling bearing and with the improved oil-lubricated rolling bearing. Through the comparative analysis, the structural superiority and realizability of the oil-lubricated rolling bearing are elaborated. It is hoped that this paper can play a certain reference function for design personnel in high-voltage flameproof motor industry.
