Through shaft tapered-tooth planet wheel side reducer with brake

Abstract

The invention belongs to the technical field of underground coal mine auxiliary conveying device spare parts and specifically relates to a through shaft tapered-tooth planet wheel side reducer with a brake. According to the shaft tapered-tooth planet wheel side reducer with the brake, the problem that the width of an overall support conveying vehicle is large due to the fact that the occupied space of a motor directly inserting wheel side reducer is large is solved. The shaft tapered-tooth planet wheel side reducer with the brake comprises an input fork frame I, a first rolling bearing, an inner supporting frame, an input shell, a small bevel gear, a large bevel gear, a through shaft, a shaft sleeve, a radial bearing, an output fork frame II, a locking nut, a brake spring, a brake block, a brake fixed sleeve, a friction plate set, an inner gear frame, a second rolling bearing, a bearing shaft sleeve, a third rolling bearing, a main transmission shaft, a sun wheel shaft, a planet wheel, a planet carrier, a right end cap, a vent plug, a high-pressure oil injection port, a small end cap, a left end cap, a rack installing hole, wheel installing screw holes and a high-pressure oil cavity. According to the shaft tapered-tooth planet wheel side reducer with the brake, the through shaft tapered-tooth planet combined reducer is adopted, power of an engine or a motor can be input through the transmission shaft, and the axial size of the reducer is reduced.

Description

technical field [0001] The invention belongs to the technical field of spare parts of underground auxiliary transportation equipment in coal mines, and in particular relates to a through-shaft bevel planetary wheel side reducer for brakes. Background technique [0002] A variety of auxiliary transportation equipment is used in coal mines, such as support trucks. Due to the narrow space of the underground roadway, uneven ground, and harsh operating environment, the support truck must have a good deceleration brake device to ensure the safety of transportation. At present, the wheel side reducer of the support truck adopts the direct plug-in method of the hydraulic motor and the reducer. This method takes up a large space in the width direction of the vehicle, resulting in a large vehicle width of the support truck, which cannot be used in coal mines. The operating conditions of the narrow roadway; in addition, the existing brake has no indicating device after the friction pla...
