Abstract
The utility model discloses an omega-shaped plane sealing gasket of a combined type oil pump, which is approximate to an omega-shaped plane curve. The omega-shaped plane sealing gasket is provided with a plane base which has a rectangular section and is approximate to an omega-shaped plane curve; a sealing line with a rectangular section is arranged above the plane base along the curve direction of the plane base; arched column bulges are uniformly distributed at the protruding side of the curve of the plane base; a rigid material framework with a rectangular section is combined above the plane base along the curve direction of the plane base. The rigid material framework with a rectangular section is combined above the plane base along the curve direction of the plane base, so that the shape of the plane sealing gasket can be kept and the plane sealing gasket is convenient to hold and install during installation.
Description
Technical field
The utility model relates to the skeleton of a kind of Omega-shaped plane sealing gasket for oil pump, particularly a kind of Omega-shaped plane sealing gasket for oil pump.
Background technique
ω shape planar sealing pad is arranged between high pressure oil pump end cap and oil pump body.ω shape planar sealing pad is the planar sealing pad of approximate ω shape plane curve.ω shape plane sealing is lined with the flat base that cross section is the approximate ω shape plane curve of rectangle, cross section be the approximate ω shape plane curve of rectangle flat base top, along the direction of a curve of pedestal, cross section to be arranged be the potted line of rectangle, ω shape planar sealing pad is elastomer, during use, is mounted in the groove of the approximate ω shape plane curve that the cross section of matching with ω shape pedestal ω shape planar sealing pad on high pressure oil pump end cap or oil pump body is rectangle.In order at an easy rate the ω shape pedestal of ω shape planar sealing pad to be embedded in the ω shape groove on high pressure oil pump end cap or oil pump body, in prior art, in Chinese patent 2,010 2 0510252.6, a kind of Omega-shaped plane sealing gasket for oil pump is disclosed, this Omega-shaped plane sealing gasket for oil pump is the planar sealing pad of approximate ω shape plane curve, ω shape plane sealing is lined with the flat base that cross section is the approximate ω shape plane curve of rectangle, cross section is the flat base top of the approximate ω shape plane curve of rectangle, along the direction of a curve of pedestal, cross section being arranged is the potted line of rectangle, cross section is that curved convex one side of flat base of the approximate ω shape plane curve of rectangle is evenly equipped with arc post projection, this Omega-shaped plane sealing gasket for oil pump is the elongated resilient body that size is less, the very soft shape that can not keep flat pad of product, when mounted, be inconvenient to hold and install.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, proposes a kind of shape that can keep flat pad, when mounted, and the combined oil pump ω shape planar sealing pad that conveniently holds and install.
The utility model is realized with the following method.
Combined oil pump ω shape planar sealing pad is the planar sealing pad of approximate ω shape plane curve, ω shape plane sealing is lined with the flat base that cross section is the approximate ω shape plane curve of rectangle, cross section is the flat base top of the approximate ω shape plane curve of rectangle, along the direction of a curve of pedestal, cross section being arranged is the potted line of rectangle, cross section is that curved convex one side of flat base of the approximate ω shape plane curve of rectangle is evenly equipped with arc post projection, cross section is the flat base top of the approximate ω shape plane curve of rectangle, direction of a curve along pedestal is compounded with the rigid material skeleton that cross section is rectangle.
The utility model in cross section is above the flat base of approximate ω shape plane curve of rectangle, along the direction of a curve of pedestal, be compounded with the rigid material skeleton that cross section is rectangle.Can keep the shape of flat pad, when mounted, conveniently hold and install.
Below in conjunction with accompanying drawing, the utility model is further described.
The accompanying drawing explanation
Fig. 1 looks schematic diagram according to the master of a kind of combined oil pump ω shape planar sealing pad of scheme of the invention proposition of the present utility model;
Fig. 2 is that schematic diagram cuts open in the side-looking office of Fig. 1;
Fig. 3 is the A-A generalized section of Fig. 2.
Embodiment
In Fig. 1 ~ Fig. 3, combined oil pump ω shape planar sealing pad 1 is the planar sealing pad of approximate ω shape plane curve, ω shape plane sealing is lined with the flat base 2 that cross section is the approximate ω shape plane curve of rectangle, cross section is the flat base top of the approximate ω shape plane curve of rectangle, along the direction of a curve of pedestal, cross section being arranged is the potted line 3 of rectangle, cross section is that curved convex one side of flat base of the approximate ω shape plane curve of rectangle is evenly equipped with arc post projection 4, cross section is the flat base top of the approximate ω shape plane curve of rectangle, direction of a curve along pedestal is compounded with the rigid material skeleton 5 that cross section is rectangle.
Above-mentioned rigid material skeleton can be the polytetrafluoroethylmaterial material skeleton.
