AI Technical Summary

Problems solved by technology

However, due to the low speed of the permanent magnet synchronous motor, generally around 100rpm, which is much lower than the speed of the asynchronous motor, the frictional resistance of the system converted to the frictional torque on the motor shaft will be very large, which will make it impossible for manpower to directly turn the car

Embodiment Construction

[0010] As shown in Fig. 1, in an embodiment of the turning device for permanent magnet synchronous motors driving escalators and moving walks of the present invention, one end of the motor shaft 7 of the permanent magnet synchronous motor 1 is provided with a group of planetary transmission gears. The barring handle 2 drives the sun gear 3 to rotate through a key connection, and the planetary gear 4 meshes with the sun gear 3 . Because the planetary gear 4 is also meshed with the internal gear 5 at the same time, and the internal gear 5 is fixed, so the planetary gear 4 not only rotates, but also revolves, which drives the rotation of the planetary carrier 6. The planet carrier 6 drives the motor shaft 7 of the permanent magnet synchronous motor 1 to rotate through the spline, so as to realize deceleration and boosting cranking. After the barring is used, the device can be unloaded, thus saving the space occupied by the setting of the barring booster.

Abstract

The present invention relates to an automatic escalator driven by permosyn motor and barring gear of automatic passenger footway, specially it is related to a manual barring gear. It utilizes the decelerating power-increasing device mounted on the permosyn motor shaft, it respectively uses the epicyclic transmission device to implement coaxial decelerating power increment or non-coaxial transmission pair to implement decelerating power increment, so as to attain the goal of manual barring.

Description

technical field [0001] The invention relates to a cranking device for driving an escalator and a moving walkway driven by a permanent magnet synchronous motor to realize manual cranking. technical background [0002] At present, the driving of escalators and moving walks all adopts the driving device composed of asynchronous motor, reducer, brake and other parts. The driving device requires a large amount of work in manufacturing and assembling. However, since there is a reducer, and its deceleration is relatively large, generally around 20, the flywheel installed on the motor can be used as the handwheel for turning when implementing turning, and the unloaded escalator or moving walk can be turned directly by manpower. . [0003] The use of permanent magnet synchronous motors to drive escalators and moving walks can save the reducer, which not only reduces the assembly workload, but also has low noise and high efficiency. However, due to the low speed of permanent magnet ...
