Abstract
The utility model discloses a kind of camshaft, including main stress axle and the camshaft main body of secondary stress axle, described main stress axle installation end is installed by welding with bearing insert, offers cavity, be provided with buffer spring in described cavity in described bearing insert；Welded and installed restraining position ring block on described main stress axle, described spacing ring is provided with component bar；It is installed by welding with the first cam on described main stress axle, described secondary stress axle is installed by welding with the second cam.A kind of camshaft described in the utility model, by the main stress axle of camshaft main body and secondary stress axle, coordinates buffer spring, component bar, wear-resisting ring, unloads the reduction of power the chamber torsion of camshaft, frictional force, thus improve the service life of camshaft；And this utility model simple in construction, the suitability is strong.
Description
Technical field
This utility model relates to a kind of camshaft.
Background technology
Camshaft is due to by the biggest torsion, and have a lot of parts, there will be bigger mill frictional force and cause the abrasion of parts, and dismantle and be inconvenient for, therefore can have a strong impact on job schedule, be the most all the method using fluting to add lubricating oil, but there will be leakage of oil for a long time in the past, the problems such as volatilization, so problem exists always.
Utility model content
The purpose of this utility model is to provide a kind of camshaft, by the main stress axle of camshaft main body and secondary stress axle, coordinates buffer spring, component bar, wear-resisting ring, unloads the reduction of power the chamber torsion of camshaft, frictional force, thus improve the service life of camshaft.
In order to achieve the above object, the technical solution of the utility model is:
A kind of camshaft, including main stress axle and the camshaft main body of secondary stress axle, described main stress axle installation end is installed by welding with bearing insert, offers cavity, be provided with buffer spring in described cavity in described bearing insert；Welded and installed restraining position ring block on described main stress axle, described spacing ring is provided with component bar；It is installed by welding with the first cam on described main stress axle, described secondary stress axle is installed by welding with the second cam.
Described main stress axle pair stress axle is integrally manufactured to be formed.
First positioning frame is installed on described first cam, dismountable first wear-resisting ring is installed in described first positioning frame；Second positioning frame is installed on described second cam, dismountable second wear-resisting ring is installed in described second positioning frame.
Main stress shaft part between described bearing insert and spacing ring offers more than 3 and unloads power chamber.
The beneficial effects of the utility model are: a kind of camshaft of the present utility model, by the main stress axle of camshaft main body and secondary stress axle, coordinate buffer spring, component bar, wear-resisting ring, unload the reduction of power the chamber torsion of camshaft, frictional force, thus improve the service life of camshaft；And this utility model simple in construction, the suitability is strong.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment 1
A kind of camshaft as shown in Figure 1, including main stress axle 1 and the camshaft main body 3 of secondary stress axle 2, described main stress axle 1 installation end is installed by welding with bearing insert 4, offers cavity 5, be provided with buffer spring 6 in described cavity 5 in described bearing insert 4；Welded and installed restraining position ring block 7 on described main stress axle 1, described spacing ring 7 is provided with component bar 8；It is installed by welding with the first cam 9 on described main stress axle 1, described secondary stress axle 2 is installed by welding with the second cam 10.
Described main stress axle 1 is secondary, and stress axle 2 is integrally manufactured forms.
First positioning frame 11 is installed on described first cam 9, dismountable first wear-resisting ring 12 is installed in described first positioning frame 11；Second positioning frame 13 is installed on described second cam 10, dismountable first wear-resisting ring 14 is installed in described second positioning frame 13.
1 section of main stress axle between described bearing insert 4 and spacing ring 7 offers more than 3 and unloads power chamber 15.
A kind of camshaft of the present embodiment, by the main stress axle of camshaft main body and secondary stress axle, coordinates buffer spring, component bar, wear-resisting ring, unloads the reduction of power the chamber torsion of camshaft, frictional force, thus improve the service life of camshaft；And this utility model simple in construction, the suitability is strong.
