Abstract

The utility model relates to a speed reducer, in particular to a rectangular-axis hypoid speed reducer. The rectangular-axis hypoid speed reducer comprises a motor shaft (1), a pinion (4) and a bull gear (5); the rectangular-axis hypoid speed reducer further comprises a small hypoid gear (2) and a big hypoid gear (3); the small hypoid gear (2) is arranged at the top end of the motor shaft (1) and meshed with the big hypoid gear (3); the pinion (4) is meshed with a shaft gear in the center of the big hypoid gear (3); and the bull gear (5) is meshed with a shaft gear in the center of the pinion (4). By adopting the hypoid gear pair, the volume of the complete speed reducer is greatly reduced on the premise of the same speed ratio, and the speed reducer is higher in relative bearing capacity and higher in relative speed ratio of the small hypoid gear, meanwhile, is smooth in running and small in noise and can meet the requirement of selecting the wider speed ratio range.

Description

Rectangular axis hypoid speed reducer

Technical field:

The utility model relates to a kind of speed reducer, relates in particular to a kind of rectangular axis hypoid 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 is decelerated to desired winding number, and obtain the mechanism of big torque.Be used for the mechanism of transferring power and motion at present, the application area of speed reducer is quite extensive, almost in the transmission system of various machinery, can see its trace, boats and ships, automobile, locomotive from the traffic tool, heavy facility for building, machining machine and tool that mechanical industry is used and automated production equipment, common household electrical appliances in the daily life, clock and watch or the like, 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.Present speed reducer structure is not compact, and the bearing capacity of small gear is not high, and relative ratio is less, fluctuation of service, and noise is big.

The model utility content:

The purpose of this utility model provides a kind of rectangular axis hypoid speed reducer, it has adopted accurate double cog wheel set, under the prerequisite of identical speed ratio, dwindled machine volume greatly, and its structure is compact, the relative bearing capacity of little accurate double sided gear gear is higher, relative ratio is bigger, simultaneously, operates steadily, noise is little, can satisfy the selection than the large speed ratio scope.

In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises motor shaft, small gear and gearwheel, it also comprises little accurate double sided gear and big hypoid gear, the top of motor shaft is provided with little accurate double sided gear, little accurate double sided gear is meshed with big hypoid gear, small gear is meshed with the shaftgear at big hypoid gear center, and gearwheel is meshed with the shaftgear at small gear center.

Little accurate double sided gear in the utility model and the big hypoid gear double cog wheel set that is as the criterion under the prerequisite of identical speed ratio, has been dwindled machine volume greatly; It is a kind of of helical bevel gear, and the center line of gear pair is disjoint, but interlace.Its compact structure, the relative bearing capacity of little accurate double sided gear are higher, and relative ratio is bigger, and operates steadily, and noise is little, can satisfy the selection than the large speed ratio scope.

Description of drawings:

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

Embodiment:

With reference to Fig. 1, this embodiment is by the following technical solutions: it comprises motor shaft 1, small gear 4 and gearwheel 5, it also comprises little accurate double sided gear 2 and big hypoid gear 3, the top of motor shaft 1 is provided with little accurate double sided gear 2, little accurate double sided gear 2 is meshed with big hypoid gear 3, small gear 4 is meshed with the shaftgear at big hypoid gear 3 centers, and gearwheel 5 is meshed with the shaftgear at small gear 4 centers.

Little accurate double sided gear 2 in this embodiment and the big hypoid gear 3 double cog wheel set that is as the criterion under the prerequisite of identical speed ratio, has been dwindled machine volume greatly; It is a kind of of helical bevel gear, and the center line of gear pair is disjoint, but interlace.Its compact structure, the relative bearing capacity of little accurate double sided gear are higher, and relative ratio is bigger, and operates steadily, and noise is little, can satisfy the selection than the large speed ratio scope.
