Abstract
The utility model relates to a thrust structure of a camshaft of an engine. The technical scheme includes that the camshaft is mounted on a body of the engine, and a gear is mounted at the outer end of the camshaft. The thrust structure of the camshaft of the engine is characterized in that an annular groove is arranged on the periphery of one end, which is close to the body of the engine, of the gear, a thrust plate is fixed onto the body of the engine, and a positioning convex edge which is clamped into the annular groove is disposed on the thrust plate. By the aid of the thrust structure of the camshaft, the integral diameter of the camshaft is reduced, accordingly, the size of a blank is reduced, and manufacturing difficulty is lowered. Simultaneously, an annular bump of the camshaft is omitted, accordingly, a thickness space of the thrust plate is saved, the distance from the end surface of the camshaft to the body is also reduced, and the dimension of the integral engine is reduced.
Description
Technical field
The utility model belongs to technical field of engines, specifically relates to a kind of thrust structure that the limiting engine camshaft moves with respect to engine body in the axial direction that is used for.
Background technique
At present; Known engine cam thrust structure is that the end at camshaft is provided with an annular protrusion; Annular protrusion is stuck in the exterior edge face of body; One thrust plate covers on annular protrusion, thrust plate is locked on the body of motor again, thereby has limited camshaft moving with respect to body in the axial direction.This kind thrust is simple in structure, compact, and is comparatively general, but annular protrusion is set on camshaft can increase blank dimension, has strengthened manufacture difficulty; Simultaneously, camshaft tip to face distance cabinet size is bigger, has also caused the increase of complete machine size, and structure is simplified inadequately.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the existing technology, and the thrust structure of the rational engine cam of a kind of compact structure is provided, and it can effectively reduce blank dimension, reduces manufacture difficulty, reduces the complete machine size simultaneously.
The technological scheme that provides according to the utility model: a kind of thrust structure of engine cam; Camshaft is installed on the engine body; Gear is installed in the camshaft outer end; It is characterized in that: said gear is provided with annular groove near the periphery of engine body one end, is fixed with thrust plate on the said engine body, and thrust plate is provided with the convex edge, location that snaps in the said annular groove.
As the further improvement of the utility model, the convex edge, location of said thrust plate and the corresponding side of annular groove are concave arc shape.
Further improvement as the utility model has oil passageway in the said thrust plate, and oil passageway is used for the machine oil in the engine body is imported in the annular groove of gear.
As the further improvement of the utility model, the filler opening of said oil passageway is arranged on thrust plate to be close on the side of engine body, and oil outlet is arranged on the concave arc shape side of convex edge, thrust plate location.
The utility model compared with prior art, advantage is: through adopting the camshaft thrust structure of the utility model, the integral diameter of camshaft diminishes, thereby has reduced blank dimension, has reduced manufacture difficulty; Because cancelled the annular protrusion of camshaft, the thickness space of also having saved thrust plate makes the camshaft end face also reduce to the distance between the body, thereby has reduced the complete machine size simultaneously.

Description of reference numerals: 1-camshaft, 2-engine body, 3-gear, 3a-annular groove, 4-thrust plate, 4a-convex edge, location, 5-bolt.
Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1, camshaft 1 is installed on the engine body 2, and gear 3 is installed in camshaft 1 outer end, and gear 3 is provided with annular groove 3a near the periphery of engine body 2 one ends; Thrust plate 4 is fixed on the engine body 2 through bolt 5; Thrust plate 4 is provided with convex edge, the location 4a that snaps in the said annular groove 3a; Like this, the thrust plate 4 that is fixed on the engine body 2 has just limited camshaft 1 moving with respect to engine body 2 in the axial direction.
As shown in Figure 1, convex edge, the location 4a of said thrust plate 4 and the corresponding side of annular groove 3a are concave arc shape, so that adapt with the shape of annular groove 3a.Have oil passageway in the said thrust plate 4, oil passageway is used for the machine oil in the engine body 2 is imported in the annular groove 3a of gear 3, to play lubricated and cooling action.The filler opening of said oil passageway is arranged on thrust plate 4 to be close on the side of engine body 2, and oil outlet is arranged on the concave arc shape side of thrust plate 4 location convex edge 4a.
The utility model compact structure is reasonable, has both reduced the blank dimension of camshaft 1, has shortened the distance of camshaft 1 end face to the body end face again, thereby has reduced the size of complete machine.
