Abstract
The utility model discloses a mud discharge chain wheel which comprises a chain wheel body, wheel teeth and tooth grooves. The wheel teeth are arranged on an outer circle of the chain wheel body, the tooth grooves are formed in the outer circle of the chain wheel body, and mud discharge grooves are circumferentially formed in one side surface and/or the other side surface of the chain wheel body and are close to the chain teeth. The mud discharge chain wheel has the advantages that the mud discharge grooves are circumferentially formed in the side surface and/or the two side surfaces of the chain wheel body and are close to the chain teeth, once mud enters the tooth grooves, the mud in the tooth grooves can directly enter the mud discharge grooves and can be discharged from the mud discharge grooves in rotation procedures, accordingly, friction between the chain wheel and a meshed chain can be reduced, and the service life of the chain wheel can be prolonged; resistance can be reduced during transmission, and accordingly the mud discharge chain wheel is high in transmission efficiency.
Description
Technical field
The utility model relates to the sprocket wheel using in a kind of mechanical field, relates in particular to the sprocket wheel using on a kind of motor bike.
Background technology
Chain transmission is to apply wider a kind of mechanical drive.It is comprised of chain and driving and driven sprocket wheel.On sprocket wheel, be shaped with the tooth of special tooth profile, rely on the engagement of sprocket teeth and chain link to transmit motion and power.
Sprocket wheel is widely used in the mechanical drive of the industries such as vehicle, textile machine, instrument at present, and sprocket wheel transmits for the power of mechanical field, and while requiring it to transmit, friction drag is little, and this is conducive to reduce the wearing and tearing of sprocket wheel, improves transmission efficiency simultaneously.
Yet, current chain wheel driving mechanism many times operates in condition situation more complicated rugged environment, as the sprocket wheel using on motor bike, many times on sprocket wheel, speckles with the foreign material such as dust or earth, this has increased the friction of sprocket wheel with engagement chain, the service life of having reduced sprocket wheel undoubtedly.But current sprocket wheel can't well be discharged dust or earth in sprocket wheel roller seating space, the gear teeth of sprocket wheel and the object of the friction between chain when out of reach reduces transmission, this causes chain foot wheel abrasion to increase, and transmission efficiency declines.
Utility model content
For above shortcomings part in prior art, the utility model provides a kind of earth of getting rid of in roller seating space that is beneficial to, and effectively reduces sprocket wheel and the friction of meshing chain, improves the spoil disposal sprocket wheel in service life.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
Spoil disposal sprocket wheel, comprises sprocket body and is arranged on the gear teeth and the roller seating space on sprocket body cylindrical, on a side of sprocket body and/or another side, the mud drainage slot near the gear teeth is set on along the circumferential direction.
As a kind of preferred version of the present utility model, the outer side edges of described mud drainage slot is positioned at the outside 1～3mm of roller seating space bottom.
As another kind of preferred version of the present utility model, the groove width 10～20mm of described mud drainage slot, groove depth 1～3mm.
The beneficial effects of the utility model are: the utility model arranges the mud drainage slot near the gear teeth on along the circumferential direction on a side of sprocket body and/or another side, in sprocket rotation process, once there be earth in roller seating space, earth in roller seating space just can directly enter in mud drainage slot, in rotary course, from mud drainage slot, discharge, reduce the friction between sprocket wheel and engagement chain, the service life of improving sprocket wheel; Resistance while simultaneously having reduced transmission, driving efficiency is higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of spoil disposal sprocket wheel.
In accompanying drawing: 1-sprocket body; 2-gear teeth; 3-roller seating space; 4-mud drainage slot.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, spoil disposal sprocket wheel, comprises sprocket body 1 and is arranged on the gear teeth 2 and the roller seating space 3 on sprocket body 1 cylindrical, on a side of sprocket body 1 and/or another side, the mud drainage slot 4 near the gear teeth 2 is set on along the circumferential direction.The outer side edges of mud drainage slot 4 is positioned at the outside 1～3mm of roller seating space 3 bottoms, and this mud drainage slot 4 plays a part spoil disposal, and the friction while reducing transmission, makes the gear teeth 2 more wear-resisting, extends the service life of sprocket wheel.
Groove width 10～the 20mm of mud drainage slot 4, groove depth 1～3mm, this mud drainage slot 4 has under the prerequisite of spoil disposal function, can't to the intensity of sprocket body 1 self and with chain stressed the exerting an influence in transmission process.
The seamed edge of mud drainage slot 4 is arc transition, and the earth that arc transition is conducive in roller seating space 3 enters in mud drainage slot 4, and discharges by mud drainage slot 4, has greatly improved spoil disposal efficiency.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
