Abstract
The utility model discloses a last sprocket of power device, including the chain wheel body, the chain wheel body comprises gear, sleeve, forms on the gear periphery to mesh just align to grid's a plurality of tooth mutually with the chain to and set up a plurality of races that form between each tooth on the gear, and the race meshes with roller on the chain mutually, is equipped with the sleeve in the middle of the gear, and the sleeve is installed on the transmission shaft, and two end and support swing joint of transmission shaft have compensatied the not enough of prior art, reasonable in design, safe and reliable.
Description
Technical field
This utility model is related to sprocket wheel, the sprocket wheel on especially a kind of power set.
Background technology
Sprocket wheel be mounted on axle by engage with chain to realize power transmission frame for movement, different size, formation,
The power that the sprocket wheel of structure is transmitted is also different, and the sprocket wheel on this power set that this practicality is newly related to can pass completely
Send larger power and the phenomenon such as skid or come off will not be produced.
Utility model content
Technical problem to be solved in the utility model is to provide the sprocket wheel on a kind of power set.
For solving above-mentioned existing technical problem, this utility model adopts following scheme：A kind of sprocket wheel on power set,
Including sprocket body, described sprocket body is made up of gear, sleeve, circumference of gear face is formed and is meshed and evenly distributed with chain
Several teeth, and it is arranged on some races formed between each tooth on gear, race is meshed with the roller on chain, tooth
It is provided with sleeve, sleeve is arranged on power transmission shaft, and power transmission shaft two end is flexibly connected with bearing in the middle of wheel.
Preferably, described sleeve is formed with hollow cylindrical.
Preferably, described gear is cast for integral type with sleeve.
Preferably, described sleeve is bonded with the connected mode of power transmission shaft.
Beneficial effect：The sprocket wheel on this power set that this utility model is related to, by the tooth on gear and chain
Groove engagement, the race on gear engage, with the roller on chain, the transmission realizing power, and conveying capacity is greatly, conventional big with some
On the mechanical transmission equipment of type.
This utility model employs the sprocket wheel on a kind of technique scheme power set of offer, compensate for prior art
Deficiency, reasonable in design, easy to operate.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 structural representation of the present utility model.
Specific embodiment
As Fig. 1,2, the sprocket wheel on a kind of power set, including sprocket body 1, described sprocket body 1 is by 3 groups of gear 2, sleeve
Become, formation on gear 2 periphery is meshed and several evenly distributed teeth 4 with chain, and be arranged on each on gear 2
The some races 5 being formed between tooth 4, race 5 is meshed with the roller on chain, is provided with sleeve 3 in the middle of gear 2, and sleeve 3 is arranged on
On power transmission shaft 6, power transmission shaft 6 two end is flexibly connected with bearing 7, and described sleeve 3 is formed with hollow cylindrical, described gear 2 and set
Cylinder 3 is integral type casting, and described sleeve 3 is bonded with the connected mode of power transmission shaft 6.
During real work, start motor, power is sent on the power transmission shaft 6 in bearing 7 motor, power transmission shaft 6 drives tooth
Wheel 2 rotation, while gear 2 circumferential average rate rotation, gear 2 drives chain to move at a same speed, now, is distributed in gear
Tooth 4 on 2 peripheries is meshed with the groove on chain, and the race 5 on gear 2 is meshed with the roller on chain, the tooth on gear 2
4 thickness are bigger than general tooth 4, when coordinating chain work, are provided that the bigger power that rotates in a circumferential direction, and improve the strong of gear 2
Degree, the sleeve 3 on gear 2 and power transmission shaft 6 pass through bonded, and sleeve 3 is hollow cylinder shape, and sleeve 3 covers in power transmission shaft 6
On length longer that is to say, that sleeve 3 is even closer with the cooperation of power transmission shaft 6 and firm, so, gear 2 is being joined with chain
During conjunction, no matter how the rotating speed of power transmission shaft 6 changes, and gear 2 can accurately be rotated with same rotating speed.
Specific embodiment described herein is only explanation for example to this utility model spirit.This utility model institute
Belong to those skilled in the art described specific embodiment can be made with various modifications or supplement or using similar
Mode substitute, but without departing from of the present utility model spirit or surmount scope defined in appended claims.
