Abstract
The utility model discloses a timing cover cap of an engine, which comprises a cover cap body, wherein bolt connection holes are formed at the periphery of the cover cap body; a section of the cover cap body is wave-type; convex edges extending from the bolt connection holes to the middle part of an outer wall surface, and grooves defined by the convex edges are arranged on and formed in the outer wall surface of the cover cap body; and reinforcing ribs extending from the bolt connection holes to the middle part of an inner wall surface are arranged on the inner wall surface of the cover cap body. According to the timing cover cap, as the section of the cover cap body is wave-type, thickness is increased effectively, but weight is not increased remarkably; the convex edges and the grooves are adopted; the local strength of a stressed part of the cover cap body can be improved; resonant frequency of the timing cover cap is changed; and resonance is reduced. The timing cover cap is applicable to various engines, and can replace the timing cover cap of the available engine.
Description
Technical field
The utility model relates to a kind of engine part, relates in particular to a kind of engine timing cover.
Background technique
Engine timing cover is assemblied on motor, and the integrated more component such as front-suspension bracket, stretcher, idle pulley above it require to have good strength and stiffness; Simultaneously, require each position to avoid resonance as far as possible, reduce noise.In order to reach above-mentioned requirements, existing engine timing cover often arranges stiffening rib at inside and outside wall, increases simultaneously wall thickness, and this causes the weight of engine timing cover to increase, and can not solve well resonance problem.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of engine timing cover, and its weight is lighter, and strength and stiffness are good, has reduced simultaneously resonance phenomenon.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of engine timing cover, comprise the cover cap body, periphery at the cover cap body is provided with bolt connecting hole, and the cross section of described cover cap body is wave-like type, is provided with the fin that is extended to the outer wall middle part by bolt connecting hole and the groove that is enclosed by fin in the outer wall of cover cap body.
As to restriction of the present utility model, be provided with by the bolt connecting hole stiffening rib that extends of section wherein at the internal face of cover cap body.
As further restriction, described stiffening rib and bolt connecting hole place rounding off.
As further limiting of the present utility model, described stiffening rib distributes as net shape.
Owing to having adopted above-mentioned technological scheme, the utility model compared with prior art, obtained technological progress is: engine timing cover provided by the utility model, the cross section is set to wave-like type, is equivalent to effectively increase thickness, and does not gain in weight significantly, fin and groove are set, can strengthen the intensity of part, the stressed place of cover cap body, change its resonant frequency, reduce the generation of resonance; Internal face at the cover cap body arranges the intensity that stiffening rib can strengthen the cover cap body further.
The utility model is applicable to can substitute the timing cover of available engine in various motors.
The utility model is described in further detail below in conjunction with Figure of description and specific embodiment.
Description of drawings
Fig. 1 is the utility model embodiment's overall structure sectional view;
Fig. 2 is A-A place partial sectional view in Fig. 1;
Fig. 3 is the plan view of engine timing cover shown in Figure 1.
In figure: 1-cover cap body, 2-bolt connecting hole, 3-fin, 4-groove, 5-stiffening rib.
Embodiment
Embodiment
as shown in Figure 1 to Figure 3, the present embodiment discloses a kind of engine timing cover, it comprises cover cap body 1, periphery at cover cap body 1 is provided with its bolt connecting hole that is connected with motor body 2, the cross section of cover cap body 1 is wave-like type, thereby its strength and stiffness have effectively been increased, and, be provided with by bolt connecting hole 2 in the outer wall of cover cap body 1 and think the fin 3 that extend the force part at outer wall middle part and enclosed the groove 4 that forms by fin 3, can further strengthen the intensity of cover cap body 1 part by fin 3, change simultaneously the resonant frequency of various piece, avoid the generation of resonating as far as possible, reduce noise.
Be provided with a plurality of stiffening ribs 5 on the internal face of cover cap body 1, these stiffening ribs 5 are extended to the middle part of cover cap body 1 by bolt connecting hole 2 places, and present distributed in grid, stiffening rib 5 and bolt connecting hole 2 place's rounding ofves, internal stress when casting to reduce, by the acting in conjunction of stiffening rib 5 and fin 3, guaranteed the intensity of this cover cap body 1.
Claims (4)
1. engine timing cover, comprise the cover cap body, periphery at the cover cap body is provided with bolt connecting hole, it is characterized in that: the cross section of described cover cap body is wave-like type, is provided with the fin that is extended to the outer wall middle part by bolt connecting hole and the groove that is enclosed by fin in the outer wall of cover cap body.
