Abstract

The invention discloses a speed reducer of a mining winch. The speed reducer comprises a lower case, an upper case, an input shaft assembly, a flat key shaft assembly, a planet carrier assembly and a bridge shaft assembly. The input shaft assembly comprises an input shaft, a through cap and a retainer cup, the flat key shaft assembly comprises a flat key shaft, a bevel gear wheel, an inner gear ring, a center gear, a retainer cup, a through cap, a brake wheel and blank caps, the inner gear ring is assembled on the flat key shaft via a tapered roller bearing, inner teeth are arranged at one end of the inner gear ring, a bevel gear is arranged at the other end of the inner gear ring, and a bevel gear on the bevel gear wheel and the bevel gear on the inner gear ring are simultaneously meshed with a bevel pinion at an end of the input shaft. A planetary transmission mode is adopted for the speed reducer of the mining winch. The novel speed reducer of the winch is high in transmission efficiency, simple in assembly process, low in cost and maintenance expense, compact in structure and convenient to operate, and is safe and reliable.

Description

technical field [0001] The invention relates to a speed reducer for transportation machinery, in particular to a mine winch speed reducer. Background technique [0002] At present, the reducer of domestic slow-speed winches or back-column winches is mainly based on worm gear transmission. This type of reducer has the disadvantages of low transmission efficiency, short life, low work efficiency, and high maintenance and repair costs. The patent number is ZL200920046257.5, which discloses a mine-used column return winch reducer. The production of this reducer overcomes the defects of the above-mentioned winch reducer, and has achieved good results in the field use process. Its operation is flexible and convenient. Safe and reliable, with low maintenance and repair costs, the long type is suitable for the narrow working space in underground coal mines, which brings great benefits to underground coal mines. However, because this type of winch reducer is multi-stage spur gear tra...
