Abstract
The invention discloses a brazing hard alloy valve lifter for an engine. The brazing hard alloy valve lifter for the engine is characterized in that a blind hole is drilled inside a lifter body, the bottom end of the blind hole is of a tapered concave arc structure, an oil hole is formed inside the lifter body on the lower side of the blind hole, the oil hole is communicated with the bottom end of the blind hole, an arc outer groove is formed in the outer side of the lower end of the lifter body, and hard alloy is embedded into the lower end face of the lifter body. Through the arrangement, the base body of the lifter is made of special alloy steel, the lifter is arranged on the engine, internal lubrication and external lubrication can be achieved, friction is reduced, the main movement inertia of the lifer is reduced through the special requirements of an internal tapered concave arc, abrasion resistance is achieved, and the lifter is not damaged.
Description
Technical field
The present invention relates to a kind of tappet, is a kind of high speed heavy-duty engine brazing hard alloy valve tappet specifically.
Background technique
Brazing hard alloy valve tappet belongs to a strength member in high speed heavy-duty engine valve mechanism, and its performance directly affects the life-span of whole match mechanism, directly affects the quality of whole motor.High speed heavy-duty engine brazing hard alloy tappet, adopted external import in the past, but external import has a lot of inconvenience: the one, and the supply of material is inconvenient, and the 2nd, the bad coordination of quality problems, the 3rd, expensive etc.
Summary of the invention
Object of the present invention is to provide that a kind of wear-resisting property is good, the motor of environmental protection and energy saving brazing hard alloy valve tappet.
To achieve these goals, the present invention is drilled with blind hole in the inside of cylinder, the bottom of described blind hole is taper nest arc structure, in the downside cylinder of blind hole, be provided with oilhole, the bottom of oilhole and blind hole connects, arc water jacket is located at the outside, lower end of cylinder, and carbide mosaic is on the lower end surface of cylinder.
By above setting, tappet matrix adopting special alloy steel making of the present invention, is arranged on motor, can realize inside and outsidely lubricated, has reduced friction, and the specific (special) requirements of interior tapered nest arc has alleviated self main movement inertia and wear resistance is not damaged again tappet.
Accompanying drawing explanation
Now the invention will be further described by reference to the accompanying drawings.
Fig. 1 is structural representation of the present invention.
In figure: 1, cylinder, 2, blind hole, 3, oilhole, 4, arc water jacket, 5, cemented carbide.
Embodiment
As shown in Figure 1, the present invention is drilled with blind hole 2 in the inside of cylinder 1, the bottom of described blind hole 2 is taper nest arc structure, in the downside cylinder 1 of blind hole 2, be provided with oilhole 3, oilhole 3 connects with the bottom of blind hole 2, arc water jacket 4 is located at the outside, lower end of cylinder 1, and cemented carbide 5 is embedded on the lower end surface of cylinder 1.By above setting, the present invention is arranged on motor, and the existence of oilhole 3 can realize inside and outsidely lubricated, has reduced friction, and the specific (special) requirements of interior tapered nest arc has alleviated self main movement inertia and wear resistance and do not damaged again tappet.
