Sliding plug door transmission device

Abstract

The invention relates to a sliding plug door transmission device. The device comprises a driving motor, a motor support, two belt pulleys and two belt clamping plates; the driving motor is arranged inthe middle position, and a swinging disc and a motor tooth-shaped belt pulley are arranged at the front end of the driving motor, wherein the swinging disc is connected with a stator of the driving motor, and the motor tooth-shaped belt pulley is connected with an output shaft of the driving motor; the motor support is used for supporting the driving motor, and two reversing wheels are symmetrically arranged on the left side and the right side of the front lower end of the motor support and are used for performing tensioning and reversing on belt transmission; the two belt pulleys are symmetrically arranged on the two sides of the reversing wheels, and a belt is arranged on the belt pulleys and the motor tooth-shaped belt pulley of the driving motor in a closed-loop surrounding mode; andthe two belt clamping plates used for outputting rectilinear motion are arranged on the belt in a skew symmetry mode along the two sides of the driving motor. According to the sliding plug door transmission device, the driving motor is arranged, the belt pulleys are symmetrically arranged on the two sides of the driving motor, the belt is arranged between the belt pulleys and the driving motor ina closed-loop surrounding mode, and the belt clamping plates are arranged on the belt, so that the transmission power output by the belt clamping plates is ensured, and the identity, the harmony and the synchronism are provided; and the motor support with an ingenious structure is arranged, so that the installation stability of the motor is improved.

Description

technical field [0001] The invention relates to the technical field of sliding door drives, in particular to a sliding door transmission device driven by a motor and a belt. Background technique [0002] In the prior art, along with the continuous development of my country's railway passenger transport, the airtightness, convenience and flexibility of train doors have gradually become its very important indicators. Therefore, a large number of new technologies have been adopted in the speed-up bus, and the plug door is one of them: the plug door is a product integrating gas, electricity and machinery. The so-called plug door mainly means that the door has two actions of plugging and pulling That is, when the door is closed, it is stuffed into the door of the car from the inside or outside of the car to make it closed and sealed; At present, the electric sliding doors used in some cities in the market are complex in technology, difficult to manufacture, and unstable in opera...
