<P>PROBLEM TO BE SOLVED: To provide a thin hoisting machine for an elevator system that can store leaked grease when any trouble is caused to a seal structure, can deal with the leakage quickly, and can reduce a shaft length. <P>SOLUTION: A ring-like projection 13 molded to be integrated with a box body 5 is arranged on the outer circumferential side of a bearing housing 18. A ring-like oil receiving cover 14 positioned on the side of a sheave 6 relative to a facing part space between a boss part 8 of the box body 5 and the bearing housing 18 is fitted to the ring-like projection 13. An oil drop space 15 is formed below the facing part space between the oil ring-like oil receiving cover 14 positioned inside the ring-like projection 13 and the box body 5. A connection cable 16 for mutually connecting stator windings 12 is arranged between the ring-like oil receiving cover 14 positioned on the outside of the ring-like projection 13 and the box body 5. An oil reservoir 23 is formed on an end surface of the box body 5 on the opposite side of the sheave 6 in a manner of communicating and of being positioned below the oil drop space 15. <P>COPYRIGHT: (C)2012,JPO&INPIT |
