Abstract
The utility model provides a camshaft chain wheel module, relates to the chain wheel module in the transmission field. This camshaft chain wheel module is provided with spacing boss on the sprocket body, the spacing boss joint of sprocket body is at the epaxial limiting groove of cam, and assembly process has been simplified to this kind of subassembly, has improved assembly efficiency, reduced the locating pin, the cost also slightly reduces. The sprocket body on still be provided with the heavy hole of variation in size, guarantee the prerequisite of sprocket intensity and dynamic balance under, accomplish the lightweight of sprocket.
Description
Technical field
The utility model relates to the chain wheel assembly in transmission device field, particularly a kind of camshaft sprocket assembly.
Background technique
At present in the machinery industry such as automobile making, internal-combustion engine, due to chain drive timing system, to have transmission accuracy high, and good stability, the advantages such as maintenance-free, are widely used in the development process of motor.Camshaft sprocket, as the link member between timing chain and camshaft, has very high effect in engine component.Because timing system component more and system assembling accuracy requirement is high, cause assembling beat slow.
Summary of the invention
The utility model proposes a kind of camshaft sprocket assembly, solve existing sprocket shaft and camshaft and assemble complicated problem, have assembly simple, easy for installation, be convenient to the advantage safeguarded.
The technological scheme that the utility model adopts is: a kind of camshaft sprocket assembly, the camshaft comprising sprocket body and fit together with sprocket body, its technological points is: described sprocket body is also provided with the limited impression with center hole and positive stop lug boss, described camshaft is provided with the restraining groove coordinated with the positive stop lug boss in sprocket body, the positive stop lug boss of sprocket body is connected in the restraining groove on camshaft, the end face of camshaft is contacted with the internal surface of the limited impression in sprocket body, the center hole of sprocket body upper limit groove is communicated with camshaft center hole in axial direction.
As a kind of preferred version of the present utility model, described sprocket body is also provided with lightening hole.
As another kind of preferred version of the present utility model, multiple lightening hole is set meeting within the scope of sprocket body bearing capacity.
As another preferred version of the present utility model, described lightening hole should be symmetrical arranged centered by the center hole of sprocket body limited impression.
As another preferred version of the present utility model, sprocket body and camshaft are fixed together the center hole that bolt is communicated with camshaft through sprocket body.
The beneficial effects of the utility model and advantage are: this camshaft sprocket assembly, sprocket body is provided with positive stop lug boss, and the positive stop lug boss of sprocket body is connected in the restraining groove on camshaft, and this assembly, simplifies assembly technology, improves efficiency of assembling; Decrease locating stud, cost also slightly reduces.Described sprocket body is also provided with the repeated hole varied in size, under ensureing sprocket wheel intensity and dynamically balanced prerequisite, accomplishes the lightweight of sprocket wheel.
