Abstract
The utility model relates to a plastic alloy chain wheel with a buffering function and multiple engagements positions, which is composed of a wheel tooth and a spoke plate. The utility model making use of plastic alloy is formed by cast moulding at one time; the spoke plate forms a dense spoke shape; convex outward tooth rings are processed at both sides of the spoke plate of the chain wheel; the surface is a regular curved surface which can be engaged with an inner chain plate. The chain wheel is characterized in that the utility model has the buffering function and multiple engagement positions, can effectively improves the stress conditions of the chain wheel and the chain in driving, saves energy, and prolongs the service life of the chain wheel and the chain.
Description
The plastic alloy sprocket wheel that the utility model provides belongs to the vitals in the chain-driven.
The existing sprocket wheel that is used for transmission, generally all be to adopt metallic material to make, the former of sprocket wheel is an entity structure, and be furnished with damping mechanism, and its shortcoming is when cooperating transmission with chain, the gear teeth load of bearing that is meshed with the roller of chain is bigger, particularly when load change, therefore impact resistance is poor, and serious wear influences working life of sprocket wheel and chain.
In order to overcome the above-mentioned shortcoming that existing sprocket wheel exists, improve the stressing conditions of chain-driven middle sprocket and chain, thereby prolong the working life of sprocket wheel and chain, the utility model provides a kind of plastic alloy sprocket wheel with buffering and the engagement of multi-section position.
Concrete technological scheme is: this sprocket wheel is made up of the gear teeth and former, and it adopts the plastic alloy material once injection moulding, and the carrier bar of sprocket wheel is made intensive width of cloth strip.Adopt this structure, in the chain-driven process, these intensive width of cloth bars can produce resiliently deformable and play buffer function when load deforms, and absorb impact energy.
These sprocket wheel former both sides are the gear ring of evagination, its surface be can with the ruled surface of inner plate engagement.This structure can make the inner plate of chain participate in engagement together with roller in transmission process, thereby shares the load that the roller engagement is born.
In order to improve wear resistance at the chain of chain-driven middle sprocket, when the injection moulding sprocket wheel, can in plastic raw material, fill a certain proportion of oiling agent and wear-resisting metallic material, make it have the function of selflubricating.
The advantage of this programme is: (1) can save great deal of steel, reduces labor intensity, and is energy-saving and cost-reducing; Reduce production costs; (2) can save the damping mechanism of setting up in the chain-driven process, to simplify complete machine structure; Power loss when (3) reducing chain-driven; (4) can realize not having oil or few oil lubrication, prolong sprocket wheel and chain and use the longevity to close.
Specify this programme embodiment below in conjunction with accompanying drawing.Fig. 1 is the structural drawing of sprocket wheel, and Fig. 2 is the plan view of Fig. 1.1 is the gear teeth among the figure, and 2 is disc, and 3 is the curved surface of the gear ring outer rim of disc both sides evagination, and 4 is carrier bar.Former 2 adopts intensive width of cloth strip, and the curved surface of the gear ring outer rim of disc both sides evagination is decided on the external form curved surface of carrier bar, should guarantee engagement good in its transmission process.Plastic raw material should have enough rigidity and intensity, and single injection-molded is filled a certain proportion of oiling agent in the plastic raw material and the visual transmission of antifriction metal (AFM) requires apolegamy.
Claims (1)
1, a kind of plastic alloy sprocket wheel of being made up of the gear teeth and former is characterized in that the sprocket wheel former is intensive width of cloth strip, and sprocket wheel former two is surveyed and be that the gear ring of evagination, its surface are the ruled surface that can mesh with inner plate.
