The invention belongs to the technical field of coal mine underground rail auxiliary transportation, and particularly relates to a transmission mechanism for a coal mine large-gradient rail tractor. The problems existing in an existing toothed rail clamping locomotive transmission mode are solved. The transmission mechanism comprises an anti-explosion traction motor, a speed reducer, a pin wheel,an axle, a steel wheel, a rack base, a rack, a sleeper, a common rail and a wet type brake. The anti-explosion traction motor is connected with the axle through the speed reducer, steel wheels are arranged at the two ends of the axle, a pin wheel is arranged in the middle of the axle, and a pin shaft and a wet brake are installed on the pin wheel. The wet type brake is mounted on the axle. The sleepers are transversely paved on the roadway ground; the two common rails are fixed to the two sides of the sleeper and support the steel wheels. The rack seat is fixed in the middle of the sleeper; and the rack is embedded right above the rack seat and is meshed with the pin shaft to transmit power. The middle rail clamping mode is adopted, the problem that steel rails on the two sides are replaced with special-shaped rails is solved, and the rail laying cost is effectively reduced.
本发明属于煤矿井下有轨辅助运输的技术领域,具体涉及一种煤矿大坡度轨道牵引车用传动机构。解决了现有齿轨卡轨机车传动形式存在的问题,包括防爆牵引电机、减速器、销轮、车轴、钢轮、齿条座、齿条、轨枕、普轨和湿式制动器;防爆牵引电机通过减速器与车轴连接,车轴两端设置钢轮,车轴中间设置有销轮,销轮上安装销轴,车轴上还设置有湿式制动器;轨枕横铺于巷道地面上;两根普轨固定于轨枕的两侧并支撑钢轮;齿条座固定于轨枕的正中间;齿条内嵌于齿条座的正上方,与销轴啮合传递动力。本发明采用中间卡轨的形式,避免了两侧钢轨更换异形轨的问题,有效降低了轨道铺设成本。
