Description
Technical field
The utility model relates to mechanical field, is specifically related to a kind of hoist reduction gear.
Background technique
Speed reducer plays coupling rotating speed and transmitting torque between prime mover and working machine or actuator, and speed reducer is a kind of relatively accurate machinery, uses its object to be reduce rotating speed, increases torque.Single-stage and multi-stage speed-reducing machine can be divided into according to transmission progression difference; Cylindrical gear reducer, conical gear reducer and circular cone-Cylinder Gear running wheel speed reducer can be divided into according to tooth factory wheel shape; Expansion, flow deviding type can be divided into again according to the setting type of transmission and enter shaft type speed reducer together.The individual components that retarder is a kind of gear transmission by being enclosed in stiff case, worm drive, pinion-endless screw transmission form, is commonly used for the speed reduction gearing between driving link and working machine.Between prime mover and working machine or actuator, play coupling rotating speed and transmitting torque, apply very extensive in modern mechanical.
Speed reducer at present used by a lot of occasion is all general, but speed reducer common in some special mechanisms can not meet its needs, such as European hoist retarder, present retarder can not meet the requirement of European hoist, structure is compact not, and noise is comparatively large, and gears meshing is stable not, run steady not, moment of torsion is less.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of compact structure, and noise is little, and gears meshing is steady, the hoist reduction gear that transmitting torque is large, i.e. a kind of hoist reduction gear.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of hoist reduction gear, comprise cabinet, input shaft, the first deboost axle, the second deboost axle and output shaft is provided with in cabinet, described input shaft is gear shaft and is divided into two sections, one section is gear shaft, another section is connected with power mechanism, primary speed-down gear is provided with between described input shaft and the first deboost axle, double-reduction gear is provided with between described first deboost axle and the second deboost axle, three grades of reduction gear are provided with between described second deboost axle and output shaft, described output shaft is gear shaft, and its output terminal is gear.
Described individual stage reduction gear is cylindrical gears.
Another section of described input shaft is connected with power mechanism by keyway, and described power mechanism is motor.
Described first deboost axle and output shaft one end are arranged in described cabinet by ball roller bearing, and the other end is arranged in described cabinet by ball bearing, and described second deboost axle two ends are all arranged in described cabinet by ball bearing.
On described output shaft, reduction gear one end is coniform, and the other end is plane.
Its working principle is: input shaft is connected with motor by the keyway on it, input shaft rotates, primary speed-down gears meshing rotates, and drives the first deboost axle to rotate, drives double-reduction gear engagement rotation, the second deboost axle is driven to rotate, drive three grades of reduction gear engagement rotation, thus drive output shaft rotation, realize slowing down, output shaft output terminal is connected with hoist by gear structure, passes out motion and moment of torsion.
The beneficial effects of the utility model are: the utility model internal mechanism distributes rationally, and ensure that compact structure, noise is low, and gears meshing is stablized, and operate steadily, transmitting torque is large.
