The invention discloses a traction machine convenient to install, which comprises a machine base (1), a stator iron core (2), a rotor shaft (3) and a traction wheel (4), one end of the machine base (1) is connected with the rotor shaft (3) through an auxiliary stress bearing (5), the other end of the machine base (1) is connected with an end cover (6), the inner side of the end cover (6) is connected with the rotor shaft (3) through a main stress bearing (7), and one end of the rotor shaft (3) penetrates through the main stress bearing (7) and is connected with a traction wheel (4) positioned at the side part of the base (1). According to the traction machine, the stress end of the rotor shaft is supported through the end cover instead of the machine base, the thickness and stress strength required by the machine base can be effectively reduced, and therefore the width size of the traction machine is reduced, and the traction machine can be suitable for the installation size of an elevator without a machine room.
本发明公开了一种便于安装的曳引机,包括机座(1)、定子铁芯(2)、转子轴(3)和曳引轮(4),所述机座(1)的一端经辅助受力轴承(5)连接转子轴(3),机座(1)的另一端连接有端盖(6),端盖(6)内侧经主受力轴承(7)连接转子轴(3),转子轴(3)一端穿过主受力轴承(7)连接位于机座(1)侧部的曳引轮(4)。本发明通过端盖代替机座对转子轴的受力端进行支撑,能够有效降低机座所需的厚度和受力强度,从而减小曳引机的宽度尺寸,使曳引机能够适用于无机房电梯的安装尺寸。
