Description
Technical field
The utility model relates to mechanical field, is specifically related to a kind of speed reducer.
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, and common speed reducer structure is compact not, noise is larger, gears meshing is stable not, and run steady not, bearing capacity is poor.
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 speed reducer that bearing capacity is strong, i.e. a kind of speed reducer.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of speed reducer, comprise cabinet, input shaft, the first deboost axle, the second deboost axle and output shaft is provided with in cabinet, described input shaft connecting end and output shaft connecting end coexist the outside of cabinet side, primary speed-down gear is provided with between described input shaft and the first deboost axle, be provided with double-reduction gear between described first deboost axle and the second deboost axle, be provided with three grades of reduction gear between described second deboost axle and output shaft, described cabinet upper surface and lower surface are all equipped with external connection device.
Described individual stage reduction gear is helical gear.
The two ends of described input shaft, the first deboost axle, the second deboost axle and output shaft are all arranged in described cabinet by ball roller bearing.
Described input shaft connecting end and output shaft connecting end are equipped with keyway.
Described external connection device is equipped with two at the upper surface of cabinet and lower surface, and its side is equipped with tapped hole.
Its working principle is: described external connection device is connected to cabinet in external agency by tapped hole, input shaft is connected with external agency connection for transmission device by the keyway on it, input shaft rotates, primary speed-down gears meshing rotates, the first deboost axle is driven to rotate, drive 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, being connected with external agency by keyway on it, is gone out Movement transmit.
The beneficial effects of the utility model are: output shaft of the present utility model and input shaft are positioned at same end face, meet special needs, internal mechanism is installed rationally, ensure that compact structure, gear of the present utility model is helical gear, so noise pin is lower, gears meshing is stablized, operate steadily, bearing capacity is strong.
