Technical field
The present invention relates to reductor technical field, a kind of compact-sized reductor of specific design.
Background technology
At present, reducing gear typically all includes power input shaft, gear drive and power output shaft, passes through gear
Transmission mechanism couples power input shaft and power output shaft, changes the speed between power input shaft and power output shaft
Difference, realize and slow down.
But in existing reductor, its gear shaft and power output shaft, the both ends of power output shaft are both needed to individually
Bearing is supported, so that its respective rotation is smooth, the quantity of such bearing is more, while can also lengthen, increase body
Volume, cause reductor cost of manufacture high.
The content of the invention
For overcome the deficiencies in the prior art, it is an object of the invention to provide a kind of compact-sized reductor, its is defeated
Shaft shares a bearing with first gear axle and coupled, and simplifies structure.
The purpose of the present invention adopts the following technical scheme that realization：
A kind of compact-sized reductor, including body, power input shaft, first gear axle, clutch shaft bearing and power
Output shaft, internal body are formed as installation cavity；Power input shaft and power output shaft are articulated in installation cavity；And power output
One end of axle is stretched out in outside installation cavity；The other end of power output shaft is provided with bearing bore；The clutch shaft bearing is installed on bearing bore
It is interior；The bearing outer ring of clutch shaft bearing and the inwall of bearing bore are affixed；The bearing inner race of clutch shaft bearing is set in first gear axle
One end is simultaneously affixed with the outer surface of first gear axle；The connection synchronous with power input shaft of the other end of first gear axle；It is described dynamic
First gear is installed with power input shaft, the first gear axle engages with first gear.
Further, the both ends of the clutch shaft bearing are equipped with end ring.
Further, second gear axle is articulated with the installation cavity, the outer surface of first gear axle is installed with the second tooth
Wheel, the second gear engage with second gear axle.
Further, the both ends of the second gear axle are articulated on body by second bearing.
Further, the clutch shaft bearing is needle bearing.
Compared with prior art, the beneficial effects of the present invention are：Its first gear axle is inputted by first gear and power
Axle couples, and power output shaft connection synchronous with first gear axle, so achievable speed changes, and first gear axle and power are defeated
Lead to a bearing connection between shaft, first gear axle is rotated with power output shaft smooth, while can also reduce deceleration
The number of bearings of machine, simplify housing construction, reduce production cost.

Embodiment
Below, with reference to accompanying drawing and embodiment, the present invention is described further, it is necessary to which explanation is, not
Under the premise of afoul, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination
Example.
A kind of compact-sized reductor as shown in Figure 1 and Figure 2, specifically include body 10, power input shaft 20,
One gear shaft 30, clutch shaft bearing 50 and power output shaft 40, it is internally formed in body 10 as installation cavity 11, power input shaft 20
And power output shaft 40 is articulated in installation cavity 11, one end of power output shaft 40 is set to stretch out in outside installation cavity 11.Specifically exist
The other end of power output shaft is provided with bearing bore 41, and above-mentioned clutch shaft bearing 50 is installed in bearing bore 41.Make clutch shaft bearing 50
Bearing outer ring and bearing bore 41 inwall it is affixed, the bearing inner race of clutch shaft bearing 50 is set in one end of first gear axle 30,
It is and affixed with the outer surface of first gear axle 30.
On the basis of said structure, using the present invention reductor when, can be by external impetus system and power input shaft 20
Synchronous connection, can start to rotate, first gear 60 can be driven to rotate, then nibbled with first gear 60 in power input shaft 20
The first gear axle 30 of conjunction rotates, and hereafter power output shaft 40 can be driven to rotate, in this way, the rotating speed that power output shaft 40 exports
It can change under the gearing of first gear 60 and first gear axle 30, realize the effect of deceleration.It is it should be noted that dynamic
The end of power output shaft 40 and the end of first gear axle 30 are pivotally connected by above-mentioned clutch shaft bearing 50, thus, make first gear
Axle 30 can rotate number of bearings that is smooth, while can also reducing reductor with power output shaft 40, simplify the structure of body 10, drop
Low production cost.
Further, in the present embodiment, end ring 51 can be equipped with the both ends of above-mentioned clutch shaft bearing 50, can be to prevent
The only axial float in installation cavity 11 of clutch shaft bearing 50, it can so stablize the mounting structure of clutch shaft bearing 50, make first gear axle
30 is stable with the draw bail of power output shaft 40.
Further, second gear axle 70 can be also articulated with installation cavity 11, it is corresponding in the outer of first gear axle 30
Surface is installed with second gear 80, and second gear 80 engages with second gear axle 70, in this way, the process that first gear axle 30 rotates
In, second gear 80 can be driven with the second gear axle 70 of the pivot joint in installation cavity 11, realize the further of first gear axle 30
Speed change, in this way, the speed discrepancy between power output shaft 40 and power input shaft 20 can obtain further change.
Further, the both ends of second gear axle 70 can be articulated on body 10 by second bearing 90, stablize second
The rotational structure of gear shaft 70.
Further, above-mentioned clutch shaft bearing 50 can be selected as needle bearing, because of the roller that needle bearing is grown equipped with thin,
Therefore radial structure is compact, therefore can further improve structural compactness using needle bearing, reduces the structure of body 10.
Above-mentioned embodiment is only the preferred embodiment of the present invention, it is impossible to the scope of protection of the invention is limited with this,
The change and replacement for any unsubstantiality that those skilled in the art is done on the basis of the present invention belong to institute of the present invention
Claimed scope.
