Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Please refer to Fig. 2-Fig. 5, in a kind of embodiment, high pressure oil pump flange arrangement provided by the utility model, comprise base 201 and center hole 203, also comprise the coupling shaft 202 being connected to base 201, first cross sectional area of base 201 is greater than the second cross sectional area of coupling shaft 202, and described first cross section and described second cross-section normal are in the axis of center hole 203; Center hole 203 runs through base 201 and coupling shaft 202, the first groove 208 is provided with between the outer wall of base 201 and center hole 203, the bottom land of the first groove 208 is also provided with the second groove 209, second groove 209 and stretches into coupling shaft 202 direction and do not run through coupling shaft 202.
Above-described embodiment is by arranging base 201 and the coupling shaft 202 of varying cross-section area, and the first groove 208, second groove 209 is set at base 201, the area of contact of high pressure oil pump flange and high pressure oil pump is reduced, increases the reliability connected, reduce difficulty of processing, convenient processing; And the structure of varying cross-section area and the first groove 208, second groove 209 can weight reductions, save material, meet the light-weighted requirement of motor, adapt to vehicle development trend.
Particularly, base 201 and the machine shaping of coupling shaft 202 one, usually adopt casting, the two is hierarchic structure, and the first cross sectional area of base 201 is greater than the second cross sectional area of coupling shaft 202.
First groove 208 and the second groove 209 are circular groove, and coaxial with center hole 203 respectively.This vibrational power flow can conveniently be processed and operate.
First groove 208 and the second groove 209 can be columned circular groove, and also can be the circular groove of conical circular groove, preferred conical, its sectional area increases to the direction away from coupling shaft 202, is convenient to the demoulding during casting, convenient processing.
First groove 208 and the second groove 209 also can be respectively counterbore, square hole or the circular hole of bar hole or other structure.First groove 208 and the second groove 209 can respectively arrange one, two or more.First groove 208 can have several, distributes along the even circumferential being the center of circle with center hole 203 center.
Distance between the outer wall of the first groove 208 with the outer wall of base 201 is equal with the distance of the outer wall of coupling shaft 209 with the outer wall of the second groove 209.By waiting setting of wall thickness, the intensity of high pressure oil pump flange can be increased, improving the reliability that motor is connected with high pressure oil pump.
Distance between the outer wall of usual first groove 208 and the outer wall of base 201 is less than 5mm.Because wall thickness is greater than 5mm when casting, to produce defective workmanship, as pore, shrinkage porosite, under be less than mm wall thickness can avoid the defect of processing technology, improve the quality of high pressure oil pump flange.Certainly, the distance between the outer wall of the first groove 208 and the outer wall of base 201 also can be greater than or equal to 5mm.
The internal diameter of the first groove 208 is equal with the internal diameter of the second groove 209.The convenient processing of this structure.
The inwall of the first groove 208 and the inwall of the second groove 209 can be positioned at same conical surface, and the cross-section area of conical surface reduces to the direction away from coupling shaft 202.
The inside of the first groove 208 and the second groove 209 is also provided with stiffening rib 207.Due to the setting of the first groove 208 and the second groove 209, easily causing the distortion of high pressure oil pump flange, the intensity of high pressure oil pump flange can be improved by increasing stiffening rib 207.
Stiffening rib 207 comprises the coaxial annular muscle arranged with center hole 203, and centrally hole 203 radial direction arrange radial rib, annular muscle and radial rib staggered.The intensity of high pressure oil pump flange can be improved further by the annular muscle that intermeshes and radial rib.Stiffening rib 207 also can only comprise annular muscle or radial rib, also can be other structure, and as being the muscle of a certain angle with center hole 203 radius, this angle can be 10 degree, 20 degree etc.
Radial rib stretches to the outer wall of the first groove 208 by the inwall of the first groove 208, and is positioned at the inside of the first groove 208, or stretches to the outer wall of the second groove 209 by the inwall of the second groove 209, and is positioned at the inside of the second groove 208.
Base 201 is also provided with and connects the tapped hole 206 of high pressure oil pump and the unthreaded hole 205 of connecting engine; Each radial rib is positioned at the line at center hole 203 center and tapped hole 206 center, or is positioned at the connection at center hole 203 center and unthreaded hole 205 center.The most weak with the position intensity of unthreaded hole 205 owing to offering tapped hole 206, make the elongation line of radial rib through the center of tapped hole 206 or the center of unthreaded hole 205, the intensity at this place can be improved.
The circumference being centrally located at described annular muscle place of tapped hole 206.The most weak with the position intensity of unthreaded hole 205 owing to offering tapped hole 206, make annular muscle place circumference through the center of tapped hole 206, the intensity at this place can be improved.
Annular muscle can arrange one or more of, has the center of circumference through tapped hole 206 at an annular muscle place at least.
Coupling shaft 202 is also provided with seal groove 210 away from one end of base 201, and projection and second groove 209 of seal groove 210 axial plane in coupling shaft 202 are staggered at the projection position of middle axial plane.This structure can play the effect of sealing, can avoid again that the wall thickness at seal groove 210 place is too thin causes remitted its fury herein, thus ensures the intensity of whole high pressure oil pump flange.
Although the utility model is described in conjunction with above embodiment, but the utility model is not limited to above-described embodiment, and only by the restriction of claim, those of ordinary skill in the art can easily modify to it and change, but do not leave essential idea of the present utility model and scope.
