Gear rail wheel height adjusting mechanism and gear rail wheel driving device

Abstract

The invention discloses a gear rail wheel height adjusting mechanism and a gear rail wheel driving device provided with the gear rail wheel height adjusting mechanism, wherein the gear rail wheel height adjusting mechanism which is installed on an axle and positioned between a wheel and a gear rail wheel comprises a hollow shaft head, an eccentric wheel, a bearing and a hollow shaft; the hollow shaft sleeves the axle, and the gear rail wheel is installed on the hollow shaft; the eccentric wheel sleeves the axle through a bearing, and the hollow shaft head sleeves the eccentric wheel and is fixedly connected with the hollow shaft. After the height of the worn gear rail wheel of the wheel is reduced, just by rotating the eccentric wheel structure, the eccentric wheel rotates around the center of the axle, meanwhile, the gear rail wheel height adjusting mechanism drives the gear rail wheel on the hollow shaft to lift relative to a wheel set, and on the premise of ensuring that the gear rail wheel is normally meshed with a rack on a circuit, the gear rail wheel height adjusting mechanism extends the use limit range of the wheel diameter, prolongs the replacement period and the servicelife of the wheel, expands the use range and improves the service performance of the gear rail vehicle.

Description

technical field [0001] The invention belongs to the technical field of rack wheel drive, and in particular relates to a rack wheel height adjustment mechanism and a rack wheel drive device. Background technique [0002] The rack car is a mining locomotive that increases the climbing ability by means of the rack on the track bed and the gear on the locomotive. At home and abroad, sufficient research has been carried out on cog rail cars, among which there are a large number of physical locomotives running on different mountain routes abroad. Although there is no rack vehicle running on mountain routes in China, its similar technology has certain applications in the field of amusement facilities and coal mining. In the traditional technology, the rack wheel is arranged between the wheels, and is generally connected to the axle by interference fit. In addition, the center of the rack wheel and the wheel are on the same height line, and they are relatively non-adjustable. In o...

Problems solved by technology

Due to this restriction, the replacement cycle and service life of the rack wheel are severely shortened, and the range and performance of the rack wheel are limited.

[0003] CN201510893200 discloses a rack wheel device, by installing the shaft seat, the rack wheel can rotate relative to the axle, but the article does not mention how to solve the above-mentioned problem of the short life of the rack wheel
