Description
Technical field
It the utility model is related to a kind of coaxial differential device.
Background technology
In general, a rotating speed can only be exported in synchronization, a rotating output shaft, can only meets that a rotating speed will
Ask.But, it is necessary to which different rotating speeds inputs simultaneously in many workplaces.Common practice is exactly to use to have different rotating speeds
Multiple rotating output shafts are completed, and this has resulted in the increase of mechanical device complexity, and reliability reduces, cost increase.While by
In the presence of multiple rotating output shafts, the placement space of plant equipment has also been extruded, it is very high particularly with space requirement
Mechanized equipment is more inconvenient.
In addition to meeting to require using multiple rotating output shafts, differential mechanism can also be used to complete to require.
The content of the invention
The utility model is in view of the above-mentioned problems, propose a kind of coaxial differential device.
Technical scheme is as follows used by the utility model solves its technical problem：
A kind of coaxial differential device, including motor, shaft coupling, main drive shaft, bearing, capping, bolt, casing, one-level tooth
Wheel, key, secondary gear, secondary driving shaft, tertiary gear, level Four gear and rotary sleeve.
Motor is connected by shaft coupling with main drive shaft.Main drive shaft is propped up respectively by means of bearing and its extension model
Support is in capping and casing.Capping is connected as a single entity by bolt and casing.One-stage gear is arranged on main drive shaft by key；One
Level gear is meshed with secondary gear；Same secondary gear is arranged on secondary driving shaft by the extension model of key.Secondary driving shaft
The upper other end installs tertiary gear, and tertiary gear is meshed with level Four gear；Level Four gear is arranged on by the extension model of key
On rotary sleeve.Therefore, main drive shaft and rotary sleeve are with regard to exportable different rotating speed.According to one-stage gear, secondary gear, three
Level gear is different with the gearratio of level Four gear, and rotary sleeve realizes the output of different rotating speeds, that is, realizes main drive shaft and rotation
The differential output of axle sleeve.
It is of the present utility model to have technical effect that：
The utility model proposes a kind of new structure differential mechanism.By means of the differential mechanism, axle sleeve and axle output can be achieved not
Same rotating speed, it is achieved thereby that the differential output of different motion part；In structure, its feature is exactly input shaft end and output shaft
End is respectively positioned on same axle, simple in construction, and functional reliability is high；Space needed for structure is few simultaneously.
Maximum feature of the present utility model is exactly to utilize two-parallel axis, realizes the differential output of different motion part；Together
When input and output end be respectively positioned on same axle, simple in construction, functional reliability is high.
Brief description of the drawings
Fig. 1 is the utility model of the whole structure diagram；
Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of coaxial differential device, including motor 1, shaft coupling 2, main drive shaft 3, bearing 4, capping 5, spiral shell
Bolt 6, casing 7, one-stage gear 8, key 9, secondary gear 10, secondary driving shaft 11, tertiary gear 12, level Four gear 13 and rotary sleeve
14。
Motor 1 is connected by shaft coupling 2 with main drive shaft 3.Main drive shaft 3 is by means of bearing 4 and its extension model
It is respectively supported on capping 5 and casing 7.Capping 5 is connected as a single entity by bolt 6 and casing 7.One-stage gear 8 is arranged on by key 9
On main drive shaft 3；One-stage gear 8 is meshed with secondary gear 10；Same secondary gear 10 is arranged on by the extension model of key 9
On secondary driving shaft 11.The other end installs tertiary gear 12 on secondary driving shaft 11, and tertiary gear 12 is meshed with level Four gear 13；Four
Level gear 13 is arranged on rotary sleeve 14 by the extension model of key 9.Therefore, main drive shaft 3 and rotary sleeve 14 can be defeated
Go out different rotating speeds.It is different according to the gearratio of one-stage gear 8, secondary gear 10, tertiary gear 12 and level Four gear 13, rotation
Axle sleeve 14 realizes the output of different rotating speeds, that is, realizes the differential output of main drive shaft 3 and rotary sleeve 14.
