Problems solved by technology
Compared with this movable escalator step steering method, when translation steering is used, the transmission device will be relatively more complicated.
Since the step steering method adopts translation steering, the problems to be solved in the whole transmission device are as follows: 1. The two traction chains driven by the steps cannot be driven synchronously by single shaft, but can only be driven simultaneously by two shafts on both sides of the step
2. The translational steering of the steps is realized by means of the support wheel assisting in meshing with the auxiliary wheel shaft of the steps, so it is necessary to solve the problem of synchronous transmission of the auxiliary meshing support wheels

Description
technical field [0001] The invention relates to a movable escalator transmission device, which is especially suitable for the transmission of public transportation escalators or moving walkways. Background technique [0002] The transmission of ordinary escalators generally adopts chain transmission, and the step steering method adopts flip steering. The transmission device mainly includes 2-3 transmission shafts, which are respectively the main drive shaft, the handrail drive shaft, and the step driven shaft (the lower end of the steering section is fish-shaped. There is no such axis in the plate structure), and its form is relatively simple. Compared with this movable escalator step steering method, when translation steering is used, the transmission device will be relatively more complicated. Since the step steering method adopts translational steering, the problems to be solved in the whole transmission device are: 1. The two traction chains driven by the steps cannot b...
