Permanent-magnetic synchronous gearless driving device for ladder

Abstract

The utility model discloses a permanent-magnetic synchronous gearless driving device for a ladder, which comprises a host machine seat. A permanent-magnetic synchronous motor is arranged on the host machine seat, a first rotating shaft is arranged in the permanent-magnetic synchronous motor, a second rotating shaft parallel to the first rotating shaft on the permanent-magnetic synchronous motor is arranged on the host machine seat, a first-stage transmission mechanism for driving the second rotating shaft to rotate is arranged between the first rotating shaft and the second rotating shaft, and a second-stage transmission mechanism for driving a ladder driving chain wheel to rotate is arranged between the second rotating shaft and the ladder driving chain wheel. With the characteristics of low power of a host machine, large driving torque, high transmission efficiency, stable transmission, low noise and the like, the permanent-magnetic synchronous gearless driving device drives the ladder to run by utilizing the permanent-magnetic synchronous motor to combine with two stages of transmission mechanisms without utilizing a speed reduction box and a gear to carry out starting.
本实用新型公开一种扶梯永磁同步无齿轮驱动装置,包括有主机座,于主机座上设置有永磁同步电机,该永磁同步电机内设置有第一转轴,主机座上设置有与该永磁同步电机上的第一转轴相平行的第二转轴,该第一转轴和第二转轴之间设置有用于带动第二转轴转动的一级传动机构,第二转轴与扶梯驱动链轮之间设置有用于带动扶梯驱动链轮转动的二级传动机构,通过永磁同步电机结合两级传动机构从而带动扶梯运行,无须通过减速箱和齿轮启动,具有主机功率小,主动转距大,传动效率高,传动平稳低噪声等特点。
