Abstract
The utility model provides an assembly for a hub and a chain wheel for a motorcycle, comprising a hub, a buffer body and a chain wheel. The chain wheel is fixedly connected with the buffer body through a bolt and a nut, a bump on the side surface of the buffer body is limited in a groove corresponding to a side surface of the hub, and a sealing ring is arranged between the shaft neck of the buffer body and a matched surface overlapped with an inner hole of the hub. An oil seal is arranged on the outside surface of the support bearing of the buffer body which is provided with a locking piece to limit the nut. The sealing ring of the utility model can seal the assembly gap between the buffer body and the hub effectively to prevent rainfall, greasy dirty and the like from entering the hub and the bearing of the buffer body so as to improve the service life of the bearing. An oil seal is used to protect the end surface bearing of the whole assembly so as to prevent rainfall, greasy dirty and the like from entering the end surface bearing through the gap. Meanwhile a locking piece is used to lock the bolt connecting the buffer body and the chain wheel to prevent the bolt from rotating, thereby improving the reliability of operation of the whole assembly.
Description
Technical field
The utility model relates to motorcycle part, especially the assembly of hub of motorcycle and sprocket wheel.
Background technology
The chain-type motor bike is delivered on the trailing wheel through the output torque with driving engine such as chain, sprocket wheel, buffer body and wheel hub usually, and then drives whole vehicle and advance.There are the problem of intaking, advance dirt easily in existing hub of motorcycle and sprocket wheel assembly, and the service life of bearing is short, and are easy between sprocket wheel and the buffer body occur becoming flexible, and have influenced the normal delivery of power.
The utility model content
The purpose of the utility model provides a kind of good airproof performance, and waterproof and oilproof is reliable, long service life, the hub of motorcycle of reliable operation and sprocket wheel assembly.
For realizing above-mentioned purpose; The utility model provides a kind of hub of motorcycle and sprocket wheel assembly, comprises wheel hub, buffer body and sprocket wheel, and sprocket wheel links to each other with screw bolt and nut is fastening with buffer body; The boss of buffer body side is limited in the hub side face corresponding groove; Between the fitting surface of buffer body collar and wheelboss inner hole overlap joint, be provided with seal ring, the backup bearing lateral surface of buffer body is provided with oil sealing, and buffer body is provided with locking plate and carries out spacing to nut.
Seal ring in the utility model can effectively seal the assembly clearance between buffer body and the wheel hub, prevents that rainwater, greasy dirt etc. from getting in the bearing of wheel hub and buffer body the service life of having improved bearing.Oil sealing is that the end face bearing portion of whole assembly is protected, and prevents that rainwater, greasy dirt etc. from getting into through the slit of end face bearing.Simultaneously, locking plate locks the tie bolt between buffer body and the sprocket wheel, prevents that it from rotating, and improved the reliability of whole assembly work.
