Abstract

The utility model relates to a bevel gear worm speed reducer which comprises a box body. An input shaft which is connected with an output end of a motor is arranged at the upper end of the box body. The bevel gear worm speed reducer is characterized in that the input shaft drives a worm to rotate through a speed changing gear set, the worm is connected with a worm gear in a matching and rotary mode, and the worm gear is fixedly and coaxially connected with an output shaft through a first flat key. After the technical scheme is adopted, the speed reducer has the advantages of being high in strength, low in noise, modularized, large in transmission torque and stable in starting.

Description

A kind of helical gear worm-gear speed reducer
Technical field
The utility model belongs to the speed reducer field, is specifically related to a kind of helical gear worm-gear speed reducer.
Background technique
Speed reducer is that a kind of power is passed on mechanism, utilizes the velocity transducer of gear, the winding number of motor (motor) is decelerated to desired winding number, and obtain the mechanism of big torque.For the mechanism of transferring power and motion, the application area of speed reducer is quite extensive at present.Almost in the transmission system of various machinery, can see its trace, from boats and ships, automobile, the locomotive of the traffic tool, heavy facility for building, the machining machine and tool that mechanical industry is used and automated production equipment, common household electrical appliances in the daily life, clock and watch etc.It uses the transmission work from big power, and to little load, accurate angle transmission can be seen the application of speed reducer, and on commercial Application, speed reducer has deceleration and increases the torque function.Therefore be widely used in the conversion equipment of speed and moment of torsion, could realize cashing function for common gear reduction is confidential by multiple Gear combination.
Summary of the invention
The utility model then provides a kind of helical gear worm-gear speed reducer in order to solve the technical problem of mentioning in the background technique.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of helical gear worm-gear speed reducer, comprise casing, described casing upper end is provided with motor output end and is connected input shaft, it is characterized in that: described input shaft drives worm screw by the speed change gear group and rotates, described worm and wheel cooperation is rotationally connected, and described worm gear is connected with the output shaft fixing coaxial by first flat key.
Described worm gear is provided with distance ring in output terminal one side of output shaft.
Described speed change gear group comprises and the coaxial high speed small gear that is connected of input shaft, described high speed small gear and the high speed gearwheel is meshing is rotationally connected, and described high speed gearwheel is connected with worm screw is coaxial.
Described high speed small gear is fixedlyed connected with input shaft is coaxial by second flat key, and described high speed gearwheel is fixedlyed connected with worm screw is coaxial by the 3rd flat key.
Described casing upper-end surface is provided with abat-vent.
After adopting above technological scheme: speed reducer has high strength, low noise, modularization, the transmission moment of torsion is big, startup is steady.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of the utility model Fig. 1.
Embodiment
