Abstract
The utility model relates to a lock-groove type camshaft with a braking S-shaped spline, which not only can directly drive an intake valve and an exhaust valve, but also is high in bearing strength and simple in structure. The lock-groove type camshaft comprises a camshaft, a raised head of the camshaft is S-shaped, a continuous arc-shaped edge is arranged at the edge of the S-shaped raised head, a spline is disposed at the tail of a shaft level of the camshaft, and an annular lock groove is rolled at the tail end of the spline. The lock-groove type camshaft has the advantages of 1, novel, reasonable and high-strength structural design, and 2, uniform stress of the raised head, long service life and capability of guaranteeing reliable matching with an manual adjusting arm.
Description
Technical field
The utility model relates to a kind ofly can directly drive the inlet and outlet door, has the force intensity of being subjected to height again, and a kind of braking S spline lock slot type camshaft simple in structure belongs to camshaft and makes the field.
Background technique
CN201310579Y, title " brake cam of automobile axle ", this mechanism comprises that cam is connected with axostylus axostyle, and axostylus axostyle and adjustment arm connecting end peripheral hardware involute splines are characterized in that axostylus axostyle is a hollow-core construction, and axostylus axostyle center and cam rotating center are on same straight line.Its deficiency: the one, the limit of spindle nose is non-arc limit, not only causes spindle nose not smooth with cooperating of other parts, and the spindle nose unbalance stress; The 2nd, axostylus axostyle adopts hollow-core construction and spindle nose welding, and its weld strength is low, easy separating between generation axostylus axostyle and spindle nose when stressed.
The model utility content
Purpose of design: avoid the deficiency in the background technique, design and a kind ofly can directly drive the inlet and outlet door, have the force intensity of being subjected to height again, a kind of braking S spline lock slot type camshaft simple in structure.
Design proposal: in order to realize above-mentioned purpose of design.1, the plush copper limit of camshaft is the design on continuous arc limit, is one of technical characteristics of the present utility model.The purpose of doing like this is: the limit of spindle nose is the arc limit, not only can guarantee the good fit of spindle nose and other parts, and can guarantee that spindle nose is stressed evenly.2, the axostylus axostyle afterbody is the design of spline, is two of technical characteristics of the present utility model.The purpose of doing like this is: realized the matched well between camshaft and the hand regulation arm, guaranteed the reliable adjustment of hand regulation arm.3, the spline end rolls the design of annular lock groove, is three of technical characteristics of the present utility model.The purpose of doing like this is: this annular lock groove matches with spline, can guarantee reliable connection the between camshaft and the hand regulation arm.
Technological scheme: a kind of braking S spline lock slot type camshaft, it comprises camshaft, and described camshaft plush copper is S-shaped, and S shape plush copper limit is continuous arc limit, and the axostylus axostyle afterbody is a spline, the spline end has rolled annular lock groove.
The utility model is compared with background technique, the one, the structural design novelty, rationally, intensity is high; The 2nd, plush copper is stressed evenly, long service life.
Description of drawings
Fig. 1 is a kind of structural representation of the S of braking spline lock slot type camshaft.
Fig. 2 is the left TV structure schematic representation of Fig. 1.
Fig. 3 is the structural representation of axle end among Fig. 1.
Embodiment
Embodiment 1: with reference to accompanying drawing 1-3.A kind of braking S spline lock slot type camshaft, it comprises camshaft 1, and described camshaft plush copper 2 is S-shaped, and S shape plush copper limit is continuous arc limit, and the axostylus axostyle afterbody is a spline 3, the spline end has rolled annular lock groove 4.
Described S shape plush copper is symmetrically distributed, and axle end is connected with S shape plush copper center and S shape plush copper is symmetrically distributed in the axostylus axostyle two ends.
The shaft of described axostylus axostyle has rolled annular groove 5.
What need understand is: though the foregoing description is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to restriction of the present utility model; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
