Abstract
An oiltight consists of a rubber body with a metal framework and a ring oiltight lip mouth, and a spring sleeved on the rubber body. The utility model is characterized in that the ring oiltight lip mouth of the rubber body is a torus oiltight lip mouth. Due to the torus shaped lip mouth is contacted with a bearing surface and has a large contacting face, the utility model can efficiently improve the sealing effect of the oiltight and is suitable for the lubricating oil sealing of shaft parts of gas engines, in particular gasoline engines.
Description
Technical field
The utility model belongs to the sealing of the band elastic packing lip of internal-combustion engine, relates to a kind of oil sealing, is the improvement of prior art, is applicable to the oil sealing of axial workpiece in the internal-combustion engine.
Background technique
Along with the continuous development of internal-combustion engine technology, petrol engine is more and more to high rotating speed, high power, the development of high torque direction, and is also more and more higher to the seal request of oil sealing.In the prior art, oil sealing is generally by including metal frame, the rubber body of annular oil seal lip is arranged, and the spring that is socketed on the rubber body constitutes; Since oil seal lip be the wire annular, with spool be line and contact, surface of contact is little, sealing effect is relatively poor.
Summary of the invention
The purpose of this utility model is intended to overcome above-mentioned deficiency of the prior art, provides a kind of oil seal lip and axle to be that face contacts, the oil sealing of the internal-combustion engine axial workpiece of good sealing effect.
Content of the present utility model is: a kind of oil sealing, and by including metal frame, the rubber body of annular oil seal lip is arranged, and the spring that is socketed on the rubber body constitutes, and it is characterized in that: the annular oil seal lip of described rubber body (4) is a toroidal surface shape oil seal lip (5).
In the content of the present utility model: the width of described toroidal surface shape oil seal lip (5) is 0.50-2mm.
Compared with prior art, the utlity model has following characteristics:
(1) since oil seal lip be planar annular, with spool be face and contact, surface of contact is big, can effectively improve the sealing effect of oil sealing;
(2) simple in structure, production and processing is easy, and is practical, is mainly used in the particularly seal oil of the axial workpiece of petrol engine of internal-combustion engine.
Description of drawings
Fig. 1 is the utility model embodiment sectional structure schematic representation;
Fig. 2 is the J part structure for amplifying schematic representation of Fig. 1, i.e. oil seal lip position partial structurtes schematic representation.
Among the figure: 1-axle, 2-spring, 3-metal frame, 4-rubber body, 5-toroidal surface shape oil seal lip.
Embodiment
Referring to each accompanying drawing.A kind of oil sealing, by including metal frame 3, the rubber body 4 of toroidal surface shape oil seal lip 5 is arranged, and the spring 2 that is socketed on the rubber body 4 constitutes; The width of toroidal surface shape oil seal lip 5 is 1.5mm.The material of rubber body 4 can adopt silicone rubber or fluorine rubber.
During use, the present embodiment oil-sealing sleeve is connected on the axle 1, and the elastic force effect of spring 2 makes toroidal surface shape oil seal lip 5 contact with axle 1 intimate face, and surface of contact is big, good sealing effect.
The utility model is not limited to this embodiment, and the utility model content is described all can be implemented.
Claims (2)
1, a kind of oil sealing, by including metal frame, the rubber body of annular oil seal lip is arranged, and the spring that is socketed on the rubber body constitutes, and it is characterized in that: the annular oil seal lip of described rubber body (4) is a toroidal surface shape oil seal lip (5).
2, by the described oil sealing of claim 1, it is characterized in that: the width of described toroidal surface shape oil seal lip (5) is 0.50-2mm.
