Embodiment
Please referring to Fig. 1-Fig. 4, Fig. 1-Fig. 4 is respectively the stereogram of different amount of the oil sump I of crank round slider that the utility model embodiment provides or end axle-movable shaft mechanism.
Shown in above-mentioned figure, this oil sump I integral body is the casing that a top has opening.At this oil sump I bottom surface 1 four jiaos; A locating face 2 is set respectively; These locating faces 2 all stretch out to the outside of oil sump body, and its bottom surface is the plane, and on each locating face 2 positioning bolt hole 2-1 are set; These positioning bolt holes 2-1 can pass holding down bolt, can whole oil sump I be fixed on the base surface (figure does not show) through above-mentioned locating face 2.
The upper-end surface 3 of this oil sump is a shaped as frame face, and this shaped as frame face is positioned at the neutral position of the length direction of whole oil sump I cross section.This shaped as frame face is at two end lines of oil sump I length direction, is connected to the bottom surface 1 of said oil sump through the curved profile 4 of symmetrically arranged evagination, and this curved profile 4 constitutes the side of the length direction of oil sump I.Side on the width direction of the side of this upper-end surface 3 and oil sump I is concordant basically.Through the structure of above-mentioned curved profile 4, the profile of whole oil sump I has better intensity.Said upper-end surface 3 is set to the shaped as frame face, make its can be better and the bottom stationary plane of body fit.
On upper-end surface 3, its four jiaos are provided with coarse-pitch thread hole 3-1 respectively, and its four limit then is provided with some fine threads hole 3-2.Oil sump I is connected with body through above-mentioned tapped hole.Because above-mentioned thick bolt hole 3-1 can bear the bigger power that tightens up, and oil sump I can be connected firmly with the body on top.Particularly can make this oil sump I can bear crankshaft rotating reliably and be carried in the reaction torque on the oil sump.
In the inside of said oil sump I, be provided with four studs 5 that connect bottom surface 1 internal surface, said curved profile 4 internal surfaces.The place, handing-over limit of this stud 5 and said bottom surface 1 and said curved profile 4 is provided with flange, makes being connected of stud 5 and they more reliable.Above-mentioned four studs 5 are symmetrical set two respectively in oil sump I length direction both sides, from oil sump I inside the intensity of whole oil sump are reinforced, and strengthen the support force of this oil sump I, avoid oil sump I under the pressure of entire mechanism, to be out of shape.
In the side of oil sump I length direction, the position near the bottom surface of promptly said curved profile 4, the both sides of a stud 5 are provided with oil discharge screw hole 6 and dipstick mounting hole 7 therein.Be arranged on stud 5 both sides, can make the influence of the intensity of oil discharge screw hole 6 and 7 couples of whole oil sump I of dipstick mounting hole reduce to minimum.
Outer surface at said oil sump I; Also be provided with some be parallel to each other and equidistance, 3 bottom begins the outer rib 8 that extends to bottom surface 1 from the upper-end surface, these outer ribs 8 are all settings on the outer surface of length direction and width direction, and extend to bottom surface 1 always; Finally; The outer rib 8 of both sides links together through the rib of bottom surface 1 relatively, and promptly outer rib 8 extends a week around the side of oil sump I, and oil sump is waled from the outside.About oil sump,, on the outer surface of the bottom surface 1 of oil sump I, form orthogonal crisscross reticular structure with the above-mentioned outer rib 8 of both sides, front and back.Above-mentioned outer rib 8 has significantly been strengthened the intensity of whole oil sump I.
The oil sump of general crankshaft & connecting need not be born the effect that locating face is provided for entire mechanism, gets final product but be connected on the body.Above-mentioned oil sump I then is the basis of entire mechanism as the oil sump that is used for circular slider-crank mechanism or end axle-movable shaft mechanism, is bearing the effect that the location is provided for entire mechanism.This just requires this oil sump I can bear the weight of entire mechanism, and bears the very high reaction torque of mechanism kinematic to its formation.Through above-mentioned design, the especially design of stud structure and outer rib makes the intensity multiplication of this oil sump.On the above-mentioned oil sump I with sufficient intensity; Through the positioning bolt hole on the locating face 2; With the thick bolt hole on the upper-end surface 3, make its with body be connected and all very reliable with being connected of base surface, can bear the effect of bigger reaction torque and can not get loose with body or base surface.Therefore, this oil sump I can bear the interconnect function between body and the immobilizing foundation face very reliably.
The internal-combustion engine that above-mentioned oil sump is used to adopt circular slider-crank mechanism or end axle-movable shaft mechanism; Promptly obtain the embodiment of the utility model internal-combustion engine; With the compressor that above-mentioned oil sump is used to adopt circular slider-crank mechanism or holds axle-movable shaft mechanism, promptly obtain the embodiment of the utility model compressor.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
