Abstract
The utility model discloses a bowl-shaped rubber sealing element, which comprises a rubber bowl body, wherein the rubber bowl body is provided with a bowl bottom and a bowl wall formed by upward extending the outer peripheral surface of the bowl bottom, and the central part of the bowl bottom is provided with a through hole-shaped central hole; the outer side surface of one end of the bowl wall far away from the bowl bottom is formed into a working surface; the outer surface of the bowl bottom is provided with 2-3 external sealing edges, the external sealing edges are formed by axially protruding the outer surface of the bowl bottom, the inner surface of the bowl bottom is provided with an internal sealing edge, and the internal sealing edges are formed by axially protruding the inner surface of the bowl bottom; 1-2 oil grooves extending around the wall of the bowl are arranged on the working surface. After the oil groove is arranged, after the bowl-shaped rubber sealing element is installed in the equipment, the working surface can be abutted against the inner wall of the equipment, lubricating oil can be stored in the oil groove, the lubricating function between the inner walls of the bowl-shaped rubber sealing element equipment is kept, friction is reduced, accordingly, abrasion to the bowl-shaped rubber sealing element is reduced, and the service life of the bowl-shaped rubber sealing element is prolonged.
Description
Technical Field
The utility model relates to a bowl type rubber seal spare.
Background
The bowl type rubber sealing element is often used for sealing elements of moving parts such as shafts or piston rods, at present, only the outer side surface of the bottom of the sealing bowl is provided with a sealing line, the sealing bowl is integrally made of rubber, the strength is low, and in the using process, because the sealing bowl is always in the friction process, the abrasion to the sealing bowl is large, and the service life of the sealing bowl is also short.
SUMMERY OF THE UTILITY MODEL
In order to solve at least part of the problems, the utility model provides a bowl-shaped rubber sealing element, which comprises a rubber bowl body, wherein the rubber bowl body is provided with a bowl bottom and a bowl wall formed by upwards extending the peripheral surface of the bowl bottom, the cross section of the bowl wall is arc-shaped, the bowl bottom is circular, and the central part of the bowl bottom is provided with a through hole-shaped central hole; the outer side surface of one end of the bowl wall far away from the bowl bottom is formed into a working surface;
the outer surface of the bowl bottom is provided with 2-3 external sealing edges, the external sealing edges are formed by axially protruding the outer surface of the bowl bottom, the inner surface of the bowl bottom is provided with an internal sealing edge, and the internal sealing edge is formed by axially protruding the inner surface of the bowl bottom; 1-2 oil grooves are provided on the working surface, which extend around the bowl wall.
In this application, set up the oil groove on the working face, set up the oil groove after, after installing equipment with bowl type rubber seal spare in, the working face can support to press on the inner wall of equipment, lubricating oil can be saved in the oil groove, keeps the lubricating function between the inner wall of bowl type rubber seal spare equipment, reduces frictional force to reduce the wearing and tearing to bowl type rubber seal spare, improve its life.
Furthermore, a rubberized fabric is arranged in the bowl wall. After the adhesive tape is arranged, the bending resistance of the bowl wall can be improved, the strength of the bowl wall is improved, the abutting pressure of the bowl wall on the inner wall of the equipment can be enhanced, and therefore the sealing performance is improved.
Furthermore, an annular reinforcing plate is arranged in the bottom of the bowl, and the reinforcing plate is made of stainless steel materials. After the reinforcing plate is arranged, the deformation resistance of the bowl bottom can be improved, the deformation of the bowl-shaped rubber sealing piece generated in the process of moving along with the piston rod and other parts can be reduced, and the service life of the bowl-shaped rubber sealing piece is prolonged.
Further, the top surface of the bowl wall is in a cone shape which is inclined inwards. This design can make the top of bowl wall face have more compliance, makes the top of bowl wall can laminate more with the inner wall of equipment, improves sealing performance.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
Referring to fig. 1, a bowl-shaped rubber sealing member comprises a rubber bowl body 20, wherein the rubber bowl body 20 is provided with a bowl bottom 21 and a bowl wall 22 formed by upward extending of the outer peripheral surface of the bowl bottom, the bowl wall 22 is arc-shaped, the bowl bottom 21 is circular, a through hole-shaped central hole 12 is formed in the central part of the bowl bottom 21, and the central hole is used for sleeving the bowl-shaped rubber sealing member on a shaft or a piston rod; the outer side of the bowl wall 22 at the end remote from the bowl bottom is formed as a work surface 24. In this embodiment, set up 2 oil grooves on the working face, this oil groove encircles the bowl wall and extends, installs back in equipment with this bowl type rubber seal, can save a certain amount of lubricating oil in the oil groove, reduces the friction between bowl type rubber seal and the equipment inner wall, improves bowl type rubber seal's life.
3 outer sealing edges 14 are arranged on the outer surface of the bowl bottom 21, the outer sealing edges 14 are formed by axially protruding from the outer surface of the bowl bottom, an inner sealing edge 13 is arranged on the inner surface of the bowl bottom 21, and the inner sealing edge 13 is formed by axially protruding from the inner surface of the bowl bottom; a rubberized fabric clip 16 is arranged in the bowl wall.
An annular reinforcing plate is arranged in the bottom of the bowl and is made of stainless steel materials.
In this embodiment, the top surface of the bowl wall is an inward-inclined cone, so that the thickness of the top of the bowl wall is reduced, the flexibility of the top of the bowl wall is increased, and the bowl-shaped rubber sealing piece can be more attached to equipment.
