Abstract
The utility model discloses a cam shaft of a gasoline engine with subtract heavy structure, it includes claviform axle body (1), a plurality of cams (2) on a body (1) are located at the interval, its characterized in that: following the axial in the axle body (1) and being equipped with central through hole (1.1), be equipped with a plurality of steel wires (3) in central through hole (1.1), whole steel wires (3) evenly distributed is in central through hole (1.1), and the both ends of steel wire (3) are fixed through end cap (4) and axle body (1) respectively, and it is tight just to be located two steel wire (3) between end cap (4). The utility model provides a cam shaft of a gasoline engine with subtract heavy structure, it makes the camshaft quality little on the basis of the rigidity that keeps the camshaft and intensity.
Description
Technical field
This utility model relates to the technical field of camshaft processing, a kind of gasoline engine cam with Lightened structure
Axle.
Background technology
Gasoline engine is as a kind of main engine, and it is widely used on various dynamic power machine, and along with modern chemical industry
The development of industry, light-duty gasoline engine has become as a direction of following gasoline engine development.And in gasoline engine, it is main zero years old
Component cam axle, in occupation of bigger weight.Because often using hollow out camshaft to realize for camshaft in the industry
The increasing camshaft using tubular in lightweight, i.e. prior art, but owing to camshaft needs to meet rigidity with strong
The requirement of degree, therefore the camshaft of tubular needs to ensure the requirement that certain wall thickness can be only achieved rigidity and intensity, and this results in
The light weight degree of this camshaft of prior art is inconspicuous.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of protruding axis for gasoline machine with Lightened structure, and it is being protected
Make camshaft quality little on the basis of holding the rigidity of camshaft and intensity.
Technical solution adopted in the utility model is: provide a kind of protruding axis for gasoline machine with Lightened structure, and it includes rod
The axle body of shape, some cams that interval is located on axle body, it is characterised in that: described axle is the most internal is provided with center vertically
Through hole, is provided with some steel wires in central through hole, whole steel wires are uniformly distributed in central through hole, and the two ends of steel wire are passed through respectively
Plug is fixed with axle body, and the steel wire between two plugs is tight.
In the central through hole of described axle body, paraxial body end positions is provided with step surface, the relative end face of two plugs respectively with
Each self-corresponding step surface leans.By step surface against, it is achieved two plugs will not relative movement so that steel wire begins
The most tight, make plug be built in axle this is internal simultaneously.
Described step surface is the conical surface, and described plug is provided with the abutment face matched with the conical surface.
This external position being positioned at corresponding to each plug of described axle is respectively equipped with cranse.Plug effect can be improved by cranse
The radial force of the axle body of end.
In the central through hole of described axle body, the position between two plugs is provided with multiple support chip, and support chip corresponds to
The position at each steel wire place is equipped with the through hole passed for steel wire, the lateral wall of support chip and the inwall of central through hole against, entirely
Portion's support chip is distributed along the axially spaced-apart of central through hole.By support chip, can make axle body by multiple uniform support forces,
Improve the bending strength of axle body.
After using above structure, the protruding axis for gasoline machine with Lightened structure of the present utility model compared with prior art have with
Lower advantage: first, under the requirement of equal bending strength, for the axle body of same size, its wall thickness can be thinner, because of
This quality is less, secondly, by support chip, can make to remain equidistant between each steel wire, the therefore bending resistance of axle body
Intensity is more superior, and support chip also makes the support force being subject on axle body more uniform simultaneously.

Detailed description of the invention
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.
This utility model provides a kind of protruding axis for gasoline machine with Lightened structure, and it includes bar-shaped axle body 1, and interval sets
Some cams 2 on axle body 1, it is characterised in that: it is provided with central through hole 1.1, center vertically in described axle body 1
Being provided with some steel wires 3 in through hole 1.1, whole steel wires 3 are uniformly distributed in central through hole 1.1, and the two ends of steel wire 3 lead to respectively
Cross plug 4 to fix with axle body 1, and the steel wire 3 between two plugs 4 is tight.
Above-mentioned plug 4 includes that, with filling the housing in chamber and netted pad, housing is provided with opening, and steel wire 3 is through plug
After 4 tight on puller system, then in described plug 4 cast inserts, material to be filled solidification after make steel wire 3 and plug
Fixing.
In the central through hole 1.1 of described axle body 1, paraxial body 1 end positions is provided with step surface 1.2, and two plugs 4 are relative
End face lean with each self-corresponding step surface 1.2 respectively.
Described step surface 1.2 is the conical surface, and described plug 4 is provided with the abutment face matched with the conical surface.
It is positioned at the position corresponding to each plug 4 outside described axle body 1 and is respectively equipped with cranse 5.
In the central through hole 1.1 of described axle body 1, the position between two plugs 4 is provided with multiple support chip 6, supports
On sheet 6, the position corresponding to each steel wire 3 place is equipped with the through hole passed for steel wire 3, the lateral wall of support chip 6 and center
The inwall of through hole 1.1 is distributed against, whole support chips 6 along the axially spaced-apart of central through hole 1.1.
Above this utility model preferred embodiment is described, but is not to be construed as limitations on claims.This reality
Being not only limited to above example with novel, its concrete structure allows to change, all protections in this utility model demand for independence
