Abstract

The utility model relates to a pneumatic braking module for an electric motor of a pneumatic braking electric motor friction plate. When compressed air is filled into a braking cylinder through air holes in the braking cylinder, a brake plate is pushed by a piston in the braking cylinder to press the motor friction plate, so as to complete the braking action. When the compressed air is released, the piston in the braking cylinder is restored, the brake plate is restored under the action of a return spring, and one braking action is completed. The utility model has the advantages that firstly, the braking cylinder does not use electricity or emit heat; secondly, the structure is simple, the braking is reliable, and the brake force is adjustable; and thirdly, the manufacturing cost and the assembly precision are low, and no fault exists basically.

Description

Motor aerobraking module

Technical field

The utility model relates to a kind of motor aerobraking module of aerobraking motor friction sheet, belongs to the aerobraking module and makes the field.

Background technique

Existing electromagnetic braking motor brake module, on structural design, owing to adopt the electromagnet movement structure, the coil in the electromagnet certainly leads to the heat heating, rectifier work also will be generated heat, power consumption is big, and faults such as rectifier burns, coil short often take place; Secondly, assembly precision requires high, the manufacture cost height.

Summary of the invention

Purpose of design: avoid the deficiency in the background technique, design a kind of motor aerobraking module that adopts pressurized air as the braking source.

Design proposal: in order to realize above-mentioned purpose of design.1, motor brake adopts the design of aerobraking cylinder as the braking source, is one of characteristics of the present utility model.The purpose of doing like this is: because the aerobraking cylinder adopts the energy of pressurized air as the braking of cylinder, therefore have only when it is braked, just need the compressed-air actuated supply of trace, its energy consumption consumption is very little, and should trace pressurized air for the parts that constitute the aerobraking cylinder, have played the effect of wind cooling temperature lowering again, thereby the braking of aerobraking cylinder is not generated heat, the deficiency that background technique exists can not take place; But not when braking, its aerobraking cylinder is not worked, and does not consume any energy, has not only saved energy consumption, and has guaranteed the working life of aerobraking cylinder.2, base has been done the design of the braking guide way of braking plate again promptly as the connection pedestal of aerobraking cylinder, is two of characteristics of the present utility model.The purpose of doing like this is: this base both can make piston in the aerobraking cylinder by predefined track guide movement exactly, thereby had guaranteed the reliable braking of braking plate.3, have a plurality of through holes on the braking plate, movable sliding sleeve and base connecting bolt are the design that is slidingly matched, and are three of characteristics of the present utility model.The purpose of doing like this is: when base, braking plate adopt countersunk screw to be connected to the casing of motor friction sheet end face, this base countersunk screw both can be connected base with motor casing effectively reliably, together braking plate has been played the effect of guide movement again with movable sliding sleeve, when braking plate is subjected to the external force promotion, braking plate can move along movable sliding sleeve, can not rotate again.4, base have a plurality of Returnning spring countersunk screws and with the design that a plurality of respective through hole on the braking plate are complementary, be four of characteristics of the present utility model.The purpose of doing like this is: make Returnning spring that a locating point be arranged, after braking plate was pushed out, when brake off, the stage clip that is positioned at braking plate braking surface one side produced resiliency urged to braking plate, makes braking plate return to the original position attitude, thereby reaches the effect that resets.5, the design of annular seal space between film cylinder bottom seat and epithelium is five of characteristics of the present utility model.The purpose of doing like this is: when pressurized air enters the annular seal space that is made of film cylinder bottom seat and epithelium by the pore on the film cylinder bottom seat, epithelium is the effect eardrum of air by compression, thereby promote outwards to move with its piston that touches mutually, piston then promotes braking plate and contacts and the motor friction sheet is braked with the generation of motor friction sheet.Its technological scheme: motor aerobraking module, braking plate is positioned at the groove of base, the opposite side of base be connected with brake cylinder and brake cylinder in piston promote the braking plate braking.

The utility model is compared with background technique, and the one, not electricity consumption of brake cylinder is not generated heat; The 2nd, simple in structure, braking is reliable, and braking force is adjustable; The 3rd, low cost of manufacture, assembly precision requires low, essentially no fault.
