Abstract
The utility model discloses an anti-single cylinder diesel engine cam shaft jumping mechanism, which comprises a gear chamber cover (3), an engine body and a camshaft (4) which is installed on the engine body. A fixing seat (5) is arranged on the end face of the camshaft (4) corresponding to the gear chamber cover (3); a regulating screw (1) is arranged on the fixing seat (5); a fastening screw nut (2) is arranged on the regulating screw (1); an axial clearance (delta) is arranged between the head of the regulating screw (1) and the end face of the camshaft (4). By adopting the structure, the axial float of the camshaft (4) can be effectively controlled by adjusting the axial clearance (delta) between the head of the regulating screw (1) and the end face of the camshaft (4). Thus, the utility model has the advantages that the axial clearance is adjusted conveniently, the axial position is exact, and the operation is stable without noise and float. The utility model can be conveniently used for machines without changing the size of the engine body and the camshaft.
Description
Technical field
The utility model relates to a kind of single cylinder diesel, particularly a kind of mechanism that prevents single cylinder diesel camshaft axial float.
Background technique
Because the accumulated error that part is made, the single cylinder diesel camshaft axially exist big gap, thereby at single cylinder diesel in running, camshaft can produce axial float, produce noise, also can cause taking place between camshaft intake and exhaust cam and the tappet harmful effects such as eccentric wear; Even to this day, there be not research unit and manufacturer on camshaft play problem, to take easy, effective solution, caused influencing single cylinder diesel quality and working life, be unfavorable for the lifting of product specification.
Summary of the invention
Have the big disadvantage of axial float in order to overcome existing single cylinder diesel camshaft, the utility model provide a kind of install easy to adjust, accurate positioning, cost low prevent single cylinder diesel camshaft play mechanism.The technological scheme that its technical problem that solves the utility model adopts comprises gear chamber cover, body and is installed in camshaft on the body, the gear chamber cover corresponding with the camshaft end face is provided with fixed base, fixed base is provided with adjusting screw, adjusting screw is provided with fastening screw nut, leaves axial clearance between adjusting screw head and the camshaft end face.
In order to improve the product mechanical strength and to help processing, reduce cost, described fixed base and gear chamber cover are connected as a single entity.
For the ease of the improvement of old product, described fixed base is fixed on the gear chamber cover.
After adopting said structure, adjust gap delta between adjusting screw head and the camshaft end face, can effectively control the axial float of camshaft by adjusting screw and fastening screw nut; Therefore have that axial clearance δ is easy to adjust, axially locating accurately, not play, noise free, advantage such as stable, and the utility model do not do any change to diesel-engine body, camshaft size, can conveniently use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an another kind of structural representation of the present utility model.
Embodiment
Shown in Figure 1, prevent the specific embodiments of single cylinder diesel camshaft play mechanism for the utility model, it comprises gear chamber cover 3, body and be installed in camshaft 4 on the body, the gear chamber cover 3 corresponding with camshaft 4 end faces is provided with fixed base 5, fixed base 5 is connected as a single entity with gear chamber cover 3, fixed base 5 is provided with adjusting screw 1, adjusting screw 1 is provided with fastening screw nut 2, leave axial clearance δ between adjusting screw 1 head and camshaft 4 end faces, axial clearance δ regulates by adjusting screw 1 and fastening screw nut 2, and this structure only needs that the single cylinder diesel gear chamber cover is made local improvement and can implement.
Fig. 2 is an another kind of specific embodiments of the present utility model, its difference is that described fixed base 5 is fixed on the gear chamber cover 3, like this, can implement as long as change the oil pump lever seat on the former single cylinder diesel gear chamber cover into fixed base 5, do not need body, camshaft size are done any change, can use easily.
Claims (3)
1, a kind of single cylinder diesel camshaft play mechanism that prevents, comprise gear chamber cover (3), body and be installed in camshaft (4) on the body, it is characterized in that: the gear chamber cover (3) corresponding with camshaft (4) end face is provided with fixed base (5), fixed base (5) is provided with adjusting screw (1), adjusting screw (1) is provided with fastening screw nut (2), leaves axial clearance (δ) between adjusting screw (1) head and camshaft (4) end face.
2, the single cylinder diesel camshaft play mechanism that prevents according to claim 1 is characterized in that: described fixed base (5) is connected as a single entity with gear chamber cover (3).
