Abstract
The utility model relates to a cylinder cover gasket of a diesel engine. Four layers of metal plates are pressed into a cylinder cover gasket body, the improvements are as follows: the inner side of the circumference of each cylinder hole on a first-layer plate is provided with a concave ring groove which is concave downwards; the inner side of the circumference of each cylinder hole on the fourth-layer plate is provided with a convex ring groove which is convex upwards; a second-layer plate and a third-layer plate are clamped by the concave ring groove and the convex ring groove; the cross section of the edge of the cylinder hole is shaped like a flare opening; the edges of each oil hole, each water hole and each tappet chamber hole on the first-layer plate are raised upwards; the edges of each oil hole, each water hole and each tappet chamber hole on the fourth-layer plate are raised downwards, and the cross section of the periphery of each hole is shaped like a flare opening; and the periphery of the gasket body is uniformly distributed with six rivets for riveting the four layers of plates. The cylinder cover gasket has the benefits of enabling all layers of plates to have elasticity, improving reliability and durability of sealing of the engine, and avoiding the problem that non-metal materials such as asbestos and the like are generated to harm the health of a human body.
Description
Technical field
The utility model belongs to Diesel Engine Technique Field, is specifically related to a kind of cylinder cover of diesel pad.
Background technique
Diesel engine is to rely on fuel to burn in cylinder combustion to produce the high speed to-and-fro motion in cylinder of explosive force promotion piston, and the sealability of cylinder head is very crucial, and cylinder-top gasket sheet material and structure are most important.Traditional cylinder head gasket is generally compound asbestos head gasket or compound no asbestos head gasket, sealing better but working life not high, so the reliability of these two kinds of pads, durability are all undesirable, and asbestos have carcinogenic effect, are unfavorable for environmental protection.
The model utility content
In order to improve motor sealing reliability, durability, to help environmental protection, the utility model provides a kind of cylinder cover for diesel engine pad that improves structure.
Improvement technological scheme of the present utility model is as follows:
A kind of cylinder cover for diesel engine pad is to become shim body by four layers of pressing metal plates, and four layers of sheet metal are respectively first laminate 1, second laminate 2, threepayer 3 and the 4th laminate 4, and correspondence offers cylinder-bore, oilhole, water hole and hole, tappet chamber on the shim body;
Each cylinder-bore inside circumference on first laminate 1 is provided with to recessed concave ring groove, each cylinder-bore inside circumference on the 4th laminate 4 is provided with convex bulge loop groove, bulge loop groove on concave ring groove on first laminate 1 and the 4th laminate 4 clamps second laminate 2 and the threepayer 3, and the cross section at cylinder-bore edge is horn mouth;
Each oilhole on first laminate 1, water hole, tappet chamber bore edges raise up, each oilhole on the 4th laminate 4, water hole, tappet chamber bore edges are to lower convexity, the cross section at each oilhole edge is horn mouth, and second laminate 2 that is held and threepayer 3 are positioned at described horn mouth middle part;
Be laid with six rivets 5 that first laminate 1, second laminate 2, threepayer 3 and the 4th laminate 4 are riveted together around the described shim body.
Between the adjacent panels of described four laminates, be provided with the silicone rubber seal layer; Locate to be provided with the silicone rubber seal floor in described cylinder-bore, oilhole, water hole, tappet chamber hole circle week.
Described first laminate 1, second laminate 2 and the 4th laminate 4 materials are stainless steel, and threepayer 3 materials are low carbon steel.
Useful technique effect of the present utility model is: cylinder-bore, oilhole, water hole, the protruding or recessed structure of tappet chamber hole circle week place's employing at four floor sheet metal make high resilience between each laminate.Stickup, stress relaxation that adopts nonmetal cylinder head gasket appearance such as asbestos and the problem that can produce carcinogen to asbestos have been solved.Improved reliability, the durability of motor sealing, stopped to produce the problem of harmful health by nonmetallic material such as asbestos.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present utility model,
Fig. 2 is the A-A generalized section of Fig. 1,
Fig. 3 is the B-B generalized section of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail by specific embodiment.
Embodiment:
Referring to Fig. 1, a kind of cylinder cover for diesel engine pad is to form shim body by four layers of pressing metal plates, four layers of sheet metal are respectively first laminate 1, second laminate 2, threepayer 3 and the 4th laminate 4, and correspondence offers cylinder-bore a, oilhole d, water hole c and tappet chamber hole e and kingbolt hole b on the shim body.
Referring to Fig. 2, each cylinder-bore inside circumference on first laminate 1 is provided with to recessed concave ring groove, each cylinder-bore inside circumference on the 4th laminate 4 is provided with convex bulge loop groove, bulge loop groove on concave ring groove on first laminate 1 and the 4th laminate 4 clamps second laminate 2 and the threepayer 3, and the cross section at cylinder-bore edge is horn mouth;
Referring to Fig. 3, each oilhole on first laminate 1, water hole, tappet chamber bore edges raise up, each oilhole on the 4th laminate 4, water hole, tappet chamber bore edges are to lower convexity, the cross section at each oilhole edge is horn mouth, and second laminate 2 that is held and threepayer 3 are positioned at described horn mouth middle part; Be laid with six rivets 5 that first laminate 1, second laminate 2, threepayer 3 and the 4th laminate 4 are riveted together around the described shim body, make cylinder cover gasket smooth, be convenient to install.
Between the adjacent panels of four laminates, be provided with the silicone rubber seal layer; Locate to be provided with the silicone rubber seal floor in described cylinder-bore, oilhole, water hole, tappet chamber hole circle week.First laminate 1, second laminate 2 and the 4th laminate 4 materials are stainless steel, and threepayer 3 materials are low carbon steel.The material hardness of threepayer 3 is greater than the material hardness of first laminate 1 and the 4th laminate 4.
Protruding or the recessed structure shape that first laminate 1 of the present utility model, the 4th laminate 4 are pressed into around cylinder-bore is used for gas seal, evagination or recessed structure are used for oil, water-stop on every side in oilhole, water hole, hole, tappet chamber for first laminate 1, the 4th laminate 4, because the hardness of threepayer 3 is higher, and two ends are in wave shape and high resilience, so pad is sealing gas, oil, water reliably, can also guarantee that pad has good endurance quality, second laminate 2 plays filling effect in whole pad.
