The invention discloses an elevator traction machine with a magnetic encoder. The elevator traction machine comprises a machine base, a rotor, a fixed main shaft, a magnetic encoder assembly, a shaft system sealing assembly and a housing assembly. The magnetic encoder assembly comprises a magnetic ring, a magnetic head, an encoder signal cable, a magnetic ring mounting piece, a magnetic head mounting seat and a magnetic head mounting piece; the shafting sealing assembly comprises a bearing, a bearing limiting device, a first sealing ring and a second sealing ring. The outer ring of the first sealing ring is mounted on the rotor in a tight fit manner, and the inner ring is in contact with the fixed main shaft; the outer ring of the second sealing ring is installed on the rotor in a tight fit mode, the inner ring of the second sealing ring makes contact with the magnetic head installation piece, and the housing assembly is installed on the outer side of the magnetic encoder assembly and used for preventing dust and grease in a well from entering the magnetic encoder assembly. The problem that machine-room-free civil engineering arrangement limits the thickness size of the traction machine can be solved, meanwhile, maintenance personnel can conveniently conduct daily maintenance in a hoistway, the structural design is reasonable, the space is compact, and reliability is high.

    本发明公开了一种具有磁编码器的电梯曳引机,包括机座、转子、固定主轴、磁编码器组件、轴系密封组件和罩壳组件;磁编码器组件包括磁环、磁头、编码器信号电缆、磁环安装件、磁头安装座和磁头安装件;轴系密封组件,包括轴承、轴承限位装置、第一密封圈和第二密封圈;第一密封圈的外圈通过紧配合安装在所述转子上,内圈与固定主轴接触;第二密封圈的外圈通过紧配合安装在所述转子上,内圈与磁头安装件接触,罩壳组件安装在磁编码器组件外侧,用于避免井道内的灰尘和油脂进入磁编码器组件。本发明不仅可以解决无机房土建布置对曳引机厚度尺寸限制的问题,同时还能方便维保人员在井道内进行日常保养维护,结构设计合理,空间紧凑,可靠性高。
