Description
Technical field
The utility model relates to mechanical field, is specifically related to a kind of special 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, 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 special reduction gear that bearing capacity is strong, i.e. a kind of special reduction gear.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of special reduction gear, comprise cabinet, input shaft, the first deboost axle, the second deboost axle and the 3rd deboost axle is provided with in cabinet, the center line of described input shaft, the first deboost axle, the second deboost axle and the 3rd deboost axle is in the same level of cabinet, 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, between described second deboost axle and the 3rd deboost axle, be provided with three grades of reduction gear.
Described individual stage reduction gear is helical gear.
Described input shaft and the first deboost axle are gear shaft, are provided with tapped hole at the connecting end of input shaft.
Described input shaft connecting end is arranged in described cabinet by two ball bearings, and the other end and each deboost axle are all arranged in described cabinet by Biserial cylindrical roller bearing.
Described individual stage reduction gear is all connected on each deboost axle by keyway.
Its working principle is: input shaft is connected with external agency by the tapped hole 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, drive the second deboost axle to rotate, drive three grades of reduction gear engagement rotation, thus drive the 3rd deboost axle to rotate, realize slowing down.
The beneficial effects of the utility model are: each axle centre of the present utility model is positioned in same level, meets special needs, ensure that compact structure, gear of the present utility model is helical gear, so noise is lower, gears meshing is stablized, operate steadily, bearing capacity is strong.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
In figure: 1, cabinet; 2, input shaft helical gear; 3, the first deboost axle one-level helical gear; 4, the first deboost axle; 5, the second deboost axle; 6, the 3rd deboost axle; 7, end cap; 8, the 3rd deboost axle helical gear; 9, the second deboost axle helical gear; 10, the first deboost axle helical gear; 11, input shaft connecting end.
