In addition, the technical solutions of the embodiments of the present utility model may be combined with each other, but it is necessary to be based on the fact that those skilled in the art can implement the technical solutions, and when the technical solutions are contradictory or cannot be implemented, the combination of the technical solutions should be considered as not existing, and not falling within the scope of protection claimed by the present utility model.

As shown in fig. 1-3, a dual-speed dual-shaft output speed reducer comprises a casing 1, wherein a plurality of transmission shafts are arranged on the casing 1, each transmission shaft mainly comprises an input shaft 21 for transmitting input power, a first output shaft 22 and a second output shaft 23, further, the input shaft 21 is provided with a first output end 211 and a second output end 212, the first output end 211 is of a worm structure, and a worm wheel 6 meshed with a worm of the first output end 211 is sleeved on the first output shaft 22, so that power output of the first output shaft 22 is realized; the second output end 212 and the second output shaft 23 are sleeved with the bevel gears 7 which are meshed with each other, so that the power output of the second output shaft 23 is realized.

In the embodiment, the speed reducer adopts the arrangement of double output shafts, so that the aim of outputting different rotating speeds and torques is fulfilled, and different working machines or actuating mechanisms can be connected at the same time, so that the working efficiency is improved, the application range is wide, and when two machines need to work, the two speed reducers do not need to be prepared for working.

Further, the housing 1 of the speed reducer includes a first housing 11 and a second housing 12, a first output end 211 and a first output shaft 22 are disposed in the first housing 11, and a second output end 212 and a second output shaft 23 are disposed in the second housing 12.

Through the arrangement of the first shell 11 and the second shell 12, namely, the first output shaft 22 is positioned in the first shell 11, and the second output shaft 23 is positioned in the second shell 12, the two output shafts are isolated in a certain sense, the interference between the two output shafts is avoided, and enough space is reserved for lubrication and heat dissipation.

Further, in order to balance the center of gravity of the speed reducer, the input shaft 21 is perpendicular to the directions of the first output shaft 22 and the second output shaft 23, respectively, so that the situation that the center of gravity is deviated to one side due to the fact that the output shaft and the input shaft 21 are positioned on the same side is avoided.

Further, the first output shaft 22 and the second output shaft 23 are oriented in opposite directions.

When both output shafts need to be connected to an external working machine, there may be mutual interference due to the volume or shape structure of the external device, and thus the orientation of the first output shaft 22 and the second output shaft 23 are set opposite to each other, and the protruding ends are located at both sides of the speed reducer, thereby avoiding the mutual interference. Besides, the situation that the gravity center is unstable due to the fact that the gravity centers are all on one side is effectively avoided, and the working stability of the speed reducer is improved.

Further, the aforementioned drive shafts, i.e. the input shaft 21, the first output shaft 22, the second output shaft 23, etc., are in a relative rotational connection with the housing 1 via bearings 3.

The bearing 3 supports the transmission shaft to do rotary motion, so that friction coefficient in the motion process is reduced, and rotary precision is ensured.

The bearing 3 is a deep groove ball bearing 3. Radial and axial loads generated by the transmission shaft during operation are borne through the deep groove ball bearing 3, and even if the transmission shaft is inclined by 2-4 degrees, the transmission shaft still can normally work through the aligning capability of the bearing 3, so that the production and manufacturing cost is reduced, and meanwhile, the phenomenon that the transmission shaft cannot normally work due to the inclination of the angle of the transmission shaft after the transmission shaft bears the radial loads during operation is avoided.

Further, the housing 1 is provided with a flange 4 at an end of the input shaft 21 extending therefrom, and the flange 4 is used for fixing the motor. The inside cover of ring flange 4 is equipped with sealing washer 5, and the outside of sealing washer 5 is laminated with ring flange 4 inner wall, and the inboard of sealing washer 5 is laminated with input shaft 21.

In the working process of the speed reducer, the sealing ring 5 can realize sound insulation to a certain extent, and due to the elastic material property, a certain margin can be provided when the input shaft 21 is subjected to proper position correction, so that the working stability of the speed reducer is improved.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that modifications and additions may be made to those skilled in the art without departing from the method of the present utility model, which modifications and additions are also to be considered as within the scope of the present utility model.
