Abstract

The utility model discloses a double-speed energy-saving speed reducer which comprises a reduction gearbox and an output shaft. The double-speed energy-saving speed reducer is characterized in that the output shaft comprises a first output shaft and a second output shaft which are coaxially arranged, the first output shaft is rotatably arranged in the reduction gearbox, the first output shaft is a hollow shaft, the second output shaft is rotatably arranged in the first output shaft, the first output shaft is in transmission connection with a first motor, the second output shaft is in transmission connection with a second motor, and the first motor and the second motor are fixedly installed on a box body of the reduction gearbox. The double-speed energy-saving speed reducer is innovative in structural design, can provide two kinds of rotation speed output in the direction of the same output shaft and has the advantage of being energy-saving.

Description

Dual-speed energy saving type speed reducer

Technical field

The utility model relates to a kind of improvement invention of speed reducer.

Background technique

The kind of speed reducer is a lot, the speed reducer that uses in the different operating occasion has different structures usually, as the speed reducer of two kinds of different rotating speeds need be provided in same output shaft direction, the method that prior art adopts is: 1. change rotating speed during by a machine operation and realize, the high control of motor cost is complicated, electric efficiency is low, and 2. motor is direct just with a kind of rotary speed working, but not energy-conservation.

Summary of the invention

In view of the deficiencies in the prior art, the purpose of this utility model aims to provide the design of a kind of innovation structure, can provide the output of two kinds of different rotating speeds, the dual-speed energy saving type speed reducer with characteristics of energy saving in same output shaft direction.

For solving the problems of the technologies described above, the utility model takes following technological scheme to finish:

Dual-speed energy saving type speed reducer, comprise speed reducer and output shaft, it is characterized in that: described output shaft is made up of first output shaft and second output shaft of coaxial setting, the revolution of first output shaft is arranged in the speed reducer, first output shaft is hollow shaft, and the revolution of second output shaft is arranged in first output shaft, and first output shaft and first motor are in transmission connection, second output shaft and second motor are in transmission connection, and first motor and second motor are fixedly mounted on the casing of speed reducer.

The dual-speed energy saving type speed reducer that the utility model provides, design by innovation structure, a traditional output shaft is changed into the inside and outside socket axle construction of being formed by first output shaft and second output shaft, and first output shaft is controlled and is driven by two different motors are independent respectively respectively with second output shaft, thereby be implemented in the output that same output shaft direction can provide two kinds of different rotating speeds, reach the purpose of efficient energy-saving.

As preferred a kind of technological scheme, first motor is installed in the side of speed reducer, and second motor is installed in the top of speed reducer, and output shaft stretches out from the bottom of speed reducer.

Description of drawings

The utility model has following accompanying drawing:

Fig. 1 is structural representation of the present utility model.
