Abstract
The utility model relates to an alloy mosaic rocker arm of an engine; a globoidal alloy block made of wear-resistant alloy or powder alloy is connected on a globoidal part where the rocker arm body is contacted with a cam in a mobile way; the friction between the cam and the rocker arm is reduced through the high wear-resistance of the globoidal alloy block, so that the alloy mosaic rocker arm gives attention to both the intensity and rigidity of the rocker arm and combines the excellent wear resistance of wear-resistant alloy so as to prolong the useful life of the cam and the rocker arm.
Description
Technical field
The utility model belongs to engine technology, is specifically related to the rocking arm of motor.
Background technique
The available engine rocking arm adopts the homology material, mostly be 20CrMo class low-carbon alloy steel, the cambered surface position that the rocking arm body contacts with camming movement, there is certain deficiency in wear-resisting property, the long-term normal performance of using the wearing and tearing back to influence the rocking arm function, the working life of having reduced rocking arm.
The model utility content
The purpose of this utility model is the problem at the prior art existence, and a kind of inserted rocking arm of alloy of motor is provided, and improves the working life of cam and rocking arm friction pair.
Technical solution of the present utility model is:
The inserted rocking arm of a kind of alloy of motor, be connected with the cambered surface alloy block that abrasion resistance alloy or sintered alloy are made at the cambered surface position that its rocking arm body contacts with camming movement, high wear resistance by the cambered surface alloy block reduces cam and rocking arm fretting wear, prolongs the working life of cam and rocking arm.
As seen, originally inlay rocking arm and be on the intensity of taking into account rocking arm, the rigidity basis, combine abrasion resistance alloy excellent abrasive energy, thereby prolong part working life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, the inserted rocking arm of this alloy is made up of rocking arm body 1 and the cambered surface alloy block 2 that cooperates with camming movement, and cambered surface alloy block 2 is connected the cambered surface position that cooperates with camming movement on the rocking arm body 1 with the rocking arm body by bonding and welding manner.Rocking arm body 1 and cambered surface alloy block 2 materials are homology not, and rocking arm body 1 material is 20CrMo, guarantee intensity, the rigidity of rocking arm, and cambered surface alloy block 2 materials is abrasion resistance alloy or sintered alloy, improve the wear resistance at this position.
Claims (2)
1, the inserted rocking arm of a kind of alloy of motor has the rocking arm body, it is characterized in that: at the cambered surface position that described rocking arm body contacts with camming movement, be connected with the cambered surface alloy block that abrasion resistance alloy or sintered alloy are made.
2, the inserted rocking arm of the alloy of motor according to claim 1 is characterized in that: described wear-resisting cambered surface alloy block is to be connected with welding manner by bonding with the rocking arm body.
