The purpose of the present disclosure is to obtain an elevator traction machine in which a bearing can be removed from a main shaft by a simple structure. The end cap (23) is provided with a plurality of threaded holes (23e). Each of the threaded holes (23e) faces an end surface (5b) of the drive sheave (5). The pushing bolts (24) are screwed into the threaded holes (23e), and the ends of the pushing bolts (24) abut against the end face (5b), so that the pushing bolts (24) are rotated, and the end cover (23) is used for pressing the bearing (22) in the direction away from the driving rope wheel (5).
本公开的目的在于得到一种电梯曳引机,其能够通过简单的结构从主轴拆下轴承。在端盖(23)设置有多个螺纹孔(23e)。各螺纹孔(23e)与驱动绳轮(5)的端面(5b)对置。在将各顶推螺栓(24)拧入螺纹孔(23e)中、且使顶推螺栓(24)的末端与端面(5b)抵接的状态下,使顶推螺栓(24)旋转,由此利用端盖(23)将轴承(22)向远离驱动绳轮(5)的方向按压。
