Description
Technical Field
The utility model relates to the technical field of chain transmission noise reduction chain wheels, in particular to a rubberizing chain wheel with an unloading structure.
Background
At present, large-displacement motorcycles are increasingly popular with the masses, the requirement on riding comfort is increasingly improved, and in order to reduce the noise of the motorcycles, the rubberized chain wheels are adopted.
The purpose of making an uproar is fallen in the combination realization that the kiss-coating sprocket mainly is through sprocket and rubber circle, and the combination mode of rubber circle and sprocket mainly has two kinds:
1. the contact surface of the rubber ring and the chain wheel is combined in a non-adhesive mode, and the mode has the advantages that the early use effect is better, because the rubber is in a free state, the impact from the chain is buffered through the elastic deformation and the outward turning deformation of the rubber, and the defect is that the outward turning deformation of the rubber quickly enables the rubber and the end surface of the chain wheel to generate a neutral position, which is equivalent to reducing the excircle size of the rubber ring, so that the interference magnitude between the chain and the rubber ring is reduced, the buffering capacity of the rubber is weakened, and the whole noise reduction effect is failed prematurely;
2. the rubber ring is combined with the contact surface of the chain wheel in a 100% viscose mode, although the defect of the mode 1 is overcome, rubber loses freedom due to the fact that the rubber is glued on the end face of the chain wheel, only a small amount of elastic deformation is used, the chain and the rubber are in a hard grinding state, a pit is quickly ground on the outer circle of the rubber, interference between the chain and the rubber ring is reduced, the effect of rubber buffering is lost, and the whole noise reduction effect is also caused to fail too early.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems existing in the prior art, the utility model provides a rubberizing chain wheel with an unloading structure.
In order to achieve the purpose, the technical scheme adopted by the novel device is as follows:
the utility model provides a take hanging of off-load structure glues sprocket, includes the sprocket body, the periphery evenly distributed of sprocket body have a plurality of teeth of a cogwheel, root and the sprocket body surface of the teeth of a cogwheel between integrated into one piece have the cross-section for the annular mounting groove of L shape, annular mounting groove and sprocket body be coaxial, the coaxial rubber circle that is equipped with on annular mounting groove, the inner wall surface and the annular mounting groove of rubber circle towards the cell wall bonding of sprocket hole one side, the rubber circle bonds with another cell wall of annular mounting groove towards the lower part of the lateral wall surface of sprocket body one side to form the adhesion zone, form non-adhesion zone between upper portion and another lateral wall, the area of adhesion zone be greater than the rubber circle 50% towards the total area of the lateral wall surface of sprocket body one side.
Preferably, the area of the bonding area is 60% of the total area of the outer surface of the side wall of the rubber ring on the side facing the chain wheel body.
Preferably, the area of the bonding area is 70% of the total area of the outer surface of the side wall of the rubber ring on the side facing the chain wheel body.
Preferably, the area of the bonding area is 80% of the total area of the outer surface of the side wall of the rubber ring on the side facing the chain wheel body.
Preferably, the area of the bonding area is 90% of the total area of the outer surface of the side wall of the rubber ring on the side facing the chain wheel body.
This novel take hanging of off-load structure to glue sprocket's beneficial effect does:
the utility model has the beneficial effects that:
1. this is novel through setting up bonding region and non-bonding region, and the non-bonding region has actually formed the off-load structure, and the bonding region has played the effect of fixed rubber circle to synthesize the advantage of 100% viscose and non-viscose dual mode, the elastic deformation of make full use of rubber circle, reduce rubber circle wearing and tearing, when the guarantee noise reduction effect, improved the life of kiss-coating sprocket.
2. This novel reasonable in design makes the work end of rubber circle be in half free state through off-load structure, has both reduced the too early phenomenon of wearing and tearing of work end of rubber circle under the 100% viscose state, has reduced the too fast deformation of work end of rubber circle under the on-stick glue attitude again and has lost effective elastic problem of buffering to the life of rubber circle has been increased.
