Abstract
The invention discloses a gasket for an engine. The gasket for the engine is provided with an installation hole for a bolt. The installation hole has multiple limiting points located on the circumference with the center of the installation hole as the circle center and the diameter as a first diameter, and groove parts far away from the center of the installation hole are arranged between the adjacent limiting points. According to the gasket for the engine, as the diameter of the limiting points is smaller than that of the bolt, the limiting points are plastically expanded when the bolt passes through the installation hole, and the bolt makes tight contact with the installation hole of the gasket. The gasket is prevented from being displaced, sealing performance of the gasket is guaranteed, and leakage is avoided.
Description
Technical field
The present invention relates to engine art, particularly a kind of pad of engine.
Background technique
The mounting hole of pad of engine is the installation passage of bolt, and it guarantees that bolt is installed fastening, prevents installing dislocation because of pad and causes leakage.In prior art, as shown in Figure 1, the bolt mounting holes of pad is unthreaded hole structure, and the diameter of bolt mounting holes is greater than the diameter of bolt.But because the gap of bolt mounting holes and bolt is large, the pad of this structure easily misplaces when mounted, there is the hidden danger of leaking.
The information being disclosed in this background technique part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide a kind of pad of engine, thus overcome the defect that existing pad of engine easily reveals.
For achieving the above object, the invention provides a kind of pad of engine, pad of engine is provided with the mounting hole for bolt, mounting hole is provided with multiple limit point, multiple limit point be positioned at the center of the mounting hole diameter that is the center of circle be the first diameter circumferentially, be provided with the groove part at the center away from mounting hole between adjacent limit point.
Preferably, in technique scheme, groove part is arcuation.
Preferably, in technique scheme, the distance between the summit of adjacent groove part and the center of mounting hole is different.
Preferably, in technique scheme, mounting hole is provided with organizes groove part more, and often organize groove part and comprise the first groove part and the second groove part, the first groove part is different with the distance between the second groove part and the center of mounting hole.
Preferably, in technique scheme, the summit of multiple first groove part be positioned at the center of the mounting hole diameter that is the center of circle for Second bobbin diameter circumferentially, the summit of multiple second groove part be positioned at the center of the mounting hole diameter that is the center of circle be the 3rd diameter circumferentially, the diameter of bolt is the 4th diameter, and wherein, Second bobbin diameter is 1.3 to 1.4 times of the 4th diameter, Second bobbin diameter is 1.1 to 1.2 times of the 4th diameter, and the first diameter is 0.85 to 0.95 times of the 4th diameter.
Compared with prior art, the present invention has following beneficial effect:
In the present invention, the diameter due to limit point is less than the diameter of bolt, and bolt will produce local plastic deformation through mounting hole, makes bolt and mounting hole close contact, prevents pad from misplacing, guarantee the sealing of pad, avoids revealing; The Second bobbin diameter of stepped setting simultaneously and the 3rd diameter grooves region, give the space of the first diameter region distortion of pad, simultaneously because stair-stepping setting makes the impact of distortion on whole pad minimum.
Accompanying drawing explanation
Fig. 1 is the structural drawing of the pad of engine of prior art.
Fig. 2 is the structural drawing according to pad of engine of the present invention.
Fig. 3 is the structural drawing according to pad of engine of the present invention.
Main Reference Numerals illustrates:
1-mounting hole, 11-first groove part, 12-second groove part, 13-limit point.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Figure 2, the mounting hole 1 for bolt is provided with according to the pad of engine of the specific embodiment of the invention, mounting hole 1 is provided with multiple limit point, the plurality of limit point be positioned at the center of mounting hole 1 diameter that is the center of circle be the first diameter D3 circumferentially, be provided with the groove part (groove part 11,12 as shown in Figure 1) at the center away from mounting hole 1 between adjacent limit point 13.
Preferably, groove part is arcuation.Preferably, the distance between the summit of adjacent groove part and the center of mounting hole is different, and the plastic deformation that the first diameter region for pad produces provides dilatating and deformable space, makes the impact of the plastic deformation at mounting hole place on pad bulk deformation minimum simultaneously.As an embodiment, as shown in Figure 2, mounting hole 1 is provided with organizes groove part more, and often organizing groove part, to comprise the first groove part 11 different with the distance between the second groove part 12 and the center of mounting hole 1 with the second groove part 12, first groove part 11.
As shown in Figure 3, the summit of multiple first groove part 11 be positioned at the center of mounting hole 1 diameter that is the center of circle for Second bobbin diameter D1 circumferentially, the summit of multiple second groove part 12 be positioned at the center of mounting hole 1 diameter that is the center of circle be the 3rd diameter D2 circumferentially, the diameter of bolt is the 4th diameter D.Preferably, Second bobbin diameter D1 is 1.3 to 1.4 times of the 4th diameter D, and the 3rd diameter D2 is 1.1 to 1.2 times of the 4th diameter D, and the first diameter D3 is 0.85 to 0.95 times of the 4th diameter D.
In the present invention, diameter due to limit point is less than the diameter of bolt, bolt will produce local plastic deformation through mounting hole, thus make said spacer mounting bores place produce certain contraction elasticity, bolt and mounting hole close contact, prevent pad from misplacing, guarantee the sealing of pad, avoid the leakage caused because of dislocation; Second bobbin diameter region and the 3rd diameter region are then that point stepped first diameter region that gives is out of shape go forward one by one space and bolt installing space, make the impact of the distortion of the first diameter region on whole pad minimum.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
