Abstract
The utility model discloses a novel light mechanical tappet structure. The top face of the tappet is a spherical face. The tappet structure is characterized in that the spherical face curvature radius is SR6000-SR60000, a phosphate coating is arranged on the surface of the spherical face, and the protruding amount of the spherical face is 2-10um. The tappet is provided with a de-weight hole. Compared with a common mechanical tappet, the weight of the novel light mechanical tappet structure can be lowered by 12% to 18%, the outer diameter phi D of the tappet contacting a cam is enlarged by about 10% to 17%, cam-tappet allowable contact stress is improved by about 20%, and through grouping dimension W, valve clearance can be adjusted quite conveniently.
Description
Technical field
The utility model relates to a kind of motor car engine field that belongs to, and is specifically related to engine valve actuating mechanism tappet structure.
Background technique
Tappet is one of most important movement parts of distribution device, and it is favourable for the high speed dynamic performance of distribution device to reduce the tappet quality, alleviates the tappet quality in addition and can reduce valve spring power, favourable to the reliability of each distribution device part.Tappet structure reasonable in design is also very important.
Summary of the invention
The utility model purpose is guaranteeing under tappet original function and the stiffness and strength prerequisite, provide a kind of in light weight, the valve clearance is easy to adjust, assemble the mechanical tappet structure of easy novel lightweight.
The utility model adopts following technological scheme for achieving the above object:
A kind of novel lightweight machinery tappet structure, described tappet end face is sphere, it is characterized in that: described sphere curvature radius SR6000 ~ SR60000, the surface has phosphating coating, protrusion amount 2 ~ 10um.
It is further characterized in that: described tappet is provided with repeated hole.
Further: the described repeated hole that goes is ellipse, circle or waist shape, evenly arranges.
With respect to mechanical tappet commonly used at present, the utility model quality can reduce by 12% ~ 18%, and it is about 10% ~ 17% that the tappet external diameter Φ D that contacts with cam increases, and cam/tappet allowable contact stress improves about 20%, by the size W of grouping, it is very convenient to regulate the valve clearance.
Description of drawings
Fig. 1 is the utility model sectional drawing.
Fig. 2 is the utility model schematic perspective view.
Embodiment
A kind of novel lightweight machinery tappet structure as shown in Figure 1, 2, described tappet is inner to be provided with projection 1 with the valve contacting point.Described tappet end face 2 is sphere, processing tappet end face 2 radius of curvature SR6000 ~ SR60000, and protrusion amount 2 ~ 10um, the surface is carried out phosphatization and is handled the formation phosphating coating.Repeated hole 3 is removed in processing uniformly on tappet, goes repeated hole 3 forms to be ellipse, circle and waist shape etc.Size W according to projection 1 is divided into 30 groups according to about 0.02mm, requires to be assembled in the motor in conjunction with the valve clearance.
Claims (3)
