Dynamic seal adjustable shuttle car wheel edge brake speed reducer and shuttle car walking system

Abstract

The invention provides a dynamic seal adjustable shuttle car wheel edge brake speed reducer and a shuttle car walking system, and belongs to the technical field of shuttle car accessories. Thewheel edge brake speed reducer comprises a hub, a first bevel gear, a first bevel gear shaft, a second bevel gear, a second bevel gear shaft, a sun gear shaft, a sun gear, a planet gear, a planet gear shaft,a planet carrier, a first shell, a second shell, an inner gear ring, a static friction plate, a dynamic friction plate, a piston, a reset screw and a reset spring. A ball cage coupler is connected with the first end cover and a hub cover installed on the hub through positioning assemblies. The brake and the wheel edge speed reducer are integrally designed, final-stage braking is achieved, other links except the final stage are damaged, the braking effect of the shuttle car is not affected, the braking reliability is improved, the spherical cage coupler is installed through the positioning assembly, and the hexagonal nut and the locking piece achieve the purpose that the adjustment spherical surface sealing compression amount is controllable; Meanwhile, the positioning protection clamping ring has positioning and dustproof functions, and the service life of the spherical seal is effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of shuttle car accessories, and specifically discloses a dynamic seal adjustable shuttle wheel side brake reducer and a shuttle car running system. Background technique [0002] The shuttle car is a trackless rubber-tyred vehicle for short-distance rapid transportation in coal mines. As one of the important equipment for short-wall mechanized mining, its main function is to transfer the coal from the continuous miner to the feeder crusher. At present, the deceleration system of the shuttle car mostly adopts a wheel-side decelerator of the shuttle car provided by the patent number ZL 201010290044.4. When the above deceleration system is actually used, there are the following deficiencies: [0003] 1) The wheel reducer is directly connected to the tires to drive the shuttle car. The wheel brake is not installed. The brake is installed on the first-stage reducer, which is a high-speed brake. If any link of the ...

AI Technical Summary

Problems solved by technology

[0003] 1) The wheel reducer is directly connected to the tires to drive the shuttle car. The wheel brake is not installed. The brake is installed on the first-stage reducer, which is a high-speed brake. If any link of the reducer is damaged, it will directly affect the shuttle. Braking performance of the car, there is a serious safety hazard;

[0004] 2) The wheel reducer is responsible for the steering function of the shuttle car, and there is no steering mechanical limit device, which may easily cause interference between the tire steering and the drive shaft;

[0005] 3) There is no mechanical overload protection device, and the overload impact may easily cause serious damage to the reducer

[0009] 1) During the installation process, the connection between the ball cage coupling and the fixed component is not easy to adjust, and it is easy to cause excessive compression of the seal;

[0010] 2) The seal is exposed to the outside world for a long time and is easily polluted
