[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

Abstract
The invention provides a dynamic seal adjustable shuttle wheel brake reducer and a shuttle car running system, which belong to the technical field of shuttle car accessories. The wheel brake reducer includes a hub, a first bevel gear, a first bevel gear shaft, Second bevel gear, second bevel gear shaft, sun gear shaft, sun gear, planetary gear, planetary gear shaft, planet carrier, first housing, second housing, ring gear, static friction plate, dynamic friction plate, piston, reset screw and reset The spring and the ball cage coupling are respectively connected with the first end cover and the hub cover installed on the wheel hub through the positioning assembly. The invention integrates the design of the brake and the wheel reducer, the final stage of braking, and other links other than the final stage are damaged, which does not affect the braking effect of the shuttle car and improves the braking reliability. The ball cage coupling is installed through the positioning component, The hexagonal nut and locking plate realize the controllable compression of the adjustable spherical seal, and the positioning protection snap ring has positioning and dustproof functions, which effectively prolongs the service life of the spherical seal.
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 ...
