Description
Technical field
The utility model relates to mechanical field, is specifically related to a kind of special worm decelerating machine.
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.
At present, but present most worm-gear speed reducer complex structure, and internal structure is compact not, causes operation steady not, uses inconvenience, the problems such as noise is large.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of simple and compact for structure, and noise is little, operates steadily, the simple special worm decelerating machine of installation and maintenance, i.e. a kind of special worm decelerating machine.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of special worm decelerating machine, comprise casing, be provided with worm gear and worm screw in described casing, described worm gear is arranged on hollow shaft, and described hollow shaft is respectively provided with bearing on worm gear both sides, install shoulder to shoulder, one step bearing is arranged on described casing, and one end is compressed by gland, below described worm gear, be provided with worm screw, described worm screw input end is arranged on described casing by bearing and back-up ring, and the other end is arranged on described casing by bearing housing, bearing and back-up ring.
Described bearing is roller bearing.
Described worm gear upper bearing (metal) outside is equipped with oil sealing, described worm screw two ends are provided with bearing, be provided with circlip, be provided with oil sealing outside described circlip outside the bearing of described worm screw input end, the described worm screw the other end is provided with bearing housing outside bearing, is provided with circlip outside described bearing housing.
Described gland is threaded connection on described casing.
Described worm gear is welded on described hollow shaft, and described worm screw input end is provided with tapped hole.
Its working principle is: worm screw one end is connected with external agency, drives worm screw to rotate, worm and wheel engagement rotation, drives hollow shaft to rotate, and realize slowing down, worm gear is connected with external agency by hollow shaft, passes rotating speed and moment of torsion.
The beneficial effects of the utility model are: internal mechanism is installed rationally, and mechanism is simple, ensure that compact structure, and gears meshing is stablized, and operate steadily, noise is lower, good airproof performance, without leakage of oil.
