Abstract
The utility model discloses a kind of camshaft, comprise axis body and at least 2 cams, described cam has fixed hole, and being through in this fixed hole of this axis body transition fit, meanwhile, the section of this axis body and the section of this fixed hole are octagon or dodecagon, and, on the sidewall of this fixed hole, Luo is connected to fastening screw trip bolt, and the inner of this fastening screw trip bolt and the outer surface of this axis body match.On described axis body between 2 adjacent cams cover to have adjustment sleeve, the inner chamber of this adjustment sleeve be also octagon or the dodecagon corresponding with the section configuration of this axis body.The utility model has the advantages that: the phase place between cam is easy to regulate, and working life is longer.
Description
Technical field
The present invention relates to technical field of transmission, especially relate to a kind of camshaft.
Background technique
Camshaft is widely used in motor etc. locates to form the action of the parts such as regular piston.Common camshaft is all formed in one, thus the phase place of cam fix, once and the wearing and tearing of certain position, whole camshaft is scrapped at once, causes certain waste.
Summary of the invention
The object of this invention is to provide a kind of camshaft, the phase place that it has between cam is easy to regulate, and the feature of growing working life.
The technical solution adopted in the present invention is: a kind of camshaft, comprise axis body and at least 2 cams, described cam has fixed hole, and being through in this fixed hole of this axis body transition fit, meanwhile, the section of this axis body and the section of this fixed hole are octagon or dodecagon, and, on the sidewall of this fixed hole, be bolted with fastening screw trip bolt, the inner of this fastening screw trip bolt and the outer surface of this axis body match.
On described axis body between 2 adjacent cams cover to have adjustment sleeve, the inner chamber of this adjustment sleeve be also octagon or the dodecagon corresponding with the section configuration of this axis body.
The advantage that the present invention has is: the phase place between cam is easy to regulate, and working life is longer.In use, cam is enclosed within on axis body camshaft of the present invention, and each cam all can carry out the angle rotation of 45 ° or 30 °, then makes can have phase difference comparatively flexibly between different cams.Meanwhile, even if wearing and tearing appear in certain cam, only need replacings, saving comparatively.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the perspective exploded view of embodiments of the invention.
In figure: 10, axis body; 20, cam, 21, fixed hole; 30, fastening screw trip bolt; 40, adjustment sleeve.
Embodiment
Embodiment, as shown in Figure 1: a kind of camshaft, comprises axis body 10 and at least 2 cams 20.Concretely, this cam 20 has fixed hole 21, and being through in this fixed hole 21 of this axis body 10 transition fit.Meanwhile, the section of the section of this axis body 10 and this fixed hole 21 is octagon or dodecagon.That is, each cam 20 is fixed after all can adjusting the angle of swing of 45 ° or 30 ° at every turn again, thereby makes can have very suitable phase difference between different cam 20, to meet different use needs and to have increased the versatility of this camshaft.And, on the sidewall of this fixed hole 21, being bolted with fastening screw trip bolt 30, the outer surface of the inner of this fastening screw trip bolt 30 and this axis body 10 matches.That is, screw after this fastening screw trip bolt 30, the inner of this fastening screw trip bolt 30 holds out against on the outer surface of this axis body 10, and the position of this cam 20 is fixed.
Further say, on this axis body 10, between 2 adjacent cams 20, cover has adjustment sleeve 40, the width of this adjustment sleeve 40 can be set as required, and the inner chamber of this adjustment sleeve 40 is also octagon or the dodecagon corresponding with the section configuration of this axis body 10.Like this, be convenient between adjacent cam 20, to there is suitable spacing.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
