Embodiment 1

[0042] Embodiment one, combining Figure 4

[0043] The oil seal assembly 1 has a group of chambers for the installation of the skeleton structure. The skeleton structure is a composite skeleton 3 (for hard materials such as some plastic parts or metal parts), and the chamber for the composite skeleton 3 is located in the oil seal assembly 1 inside, and has a groove connecting the slope on the lip 102 (the groove here is used for the disassembly and assembly of the composite skeleton 3), thanks to the skeleton structure set in the oil seal assembly 1, when the skeleton structure is the composite skeleton 3, choose The annular sealing ring 2 is made of the same material as the oil seal assembly 1. Because the composite skeleton 3 serves as a skeleton structure to provide a relatively stable connection gap, it is suitable for a shaft structure that considers the influence of friction.

Embodiment 2

[0044] Embodiment two, combining Figure 4 , Figure 5 and Figure 6

[0045] The oil seal assembly 1 has a group of chambers for the installation of the skeleton structure. The skeleton structure is the spring 4, and the chamber for the installation of the spring 4 is located at the bottom of the oil seal assembly 1, and there is a limit spring 4. funnel-shaped stoma (here the stoma structure is used), when the skeleton structure is spring-4, the lip 102 is displaced to the axial direction under the action of the spring-4 centripetal elastic force, and the cavity in which the composite skeleton 3 is installed The chamber provides a space for elastic deformation and extension of the lip 102, and with the pressure deformation brought by the abutment block 9 at the top of the oil seal assembly 1, the adjustment of the centripetal pressure is realized, and it is suitable for shaft structures that do not need to consider the influence of friction.

Embodiment 3

[0047] The oil seal assembly (1) is made of wear-resistant and aging-resistant rubber material, and the rubber material is composed of the following component raw materials in parts by weight:

[0048] 100 parts of acrylate rubber, 70 parts of nitrile rubber, 3 parts of silane coupling agent, 2 parts of dicumyl peroxide, 6 parts of nano-silicon carbide, 5 parts of nano-zinc oxide, 5 parts of nano-titanium dioxide, 2 parts of alumina fiber , 3 parts by weight of graphite powder, 1 part of stearic acid, and 1 part of sulfur powder.

[0049] The nano-silicon carbide particle size is 30nm, the nano-zinc oxide particle size is 40nm, and the nano-titanium dioxide particle size is 20nm; the alumina fiber diameter is 5um, and the monofilament length is 40mm;

[0050] The preparation method of above-mentioned rubber material, comprises the steps:

[0051] 1. Mix 100 parts of acrylate rubber, 70 parts of nitrile rubber, 3 parts of silane coupling agent, 2 parts of dicumyl peroxide, 6 p...

Abstract

The invention discloses a rubber oil seal and a press sealing device thereof. The rubber oil seal is provided with an annular oil seal assembly and a press sealing disc assembled on one side of the oil seal assembly, an annular sealing ring is embedded in the inner edge face of the oil seal assembly, a sealing ring assembling groove is formed in the position, where the annular sealing ring is embedded, of the inner edge of the oil seal assembly, and the oil seal assembly wraps the outer edge face of the annular sealing ring. An outer wall abutting against the installation position is constructed on the outer edge face of the oil seal assembly, an annular lip edge is arranged at the bottom end of the inner edge face of the oil seal assembly, and a framework structure for controlling the deformation degree of the lip edge in the axis direction of the oil seal assembly is arranged in the oil seal assembly. A plurality of sets of abutting blocks are arranged on the side, facing the oil seal assembly, of the press sealing disc, the multiple sets of abutting blocks are arranged around the axis of the press sealing disc in an annular array mode, and a pressing and covering mechanism which applies oblique pressure to the abutting blocks and is adjustable in pressure is further arranged in the press sealing disc. According to the rubber oil seal and the press sealing device thereof, the structure is reasonable, selective installation can be easily carried out according to the requirements of a shaft rod, lip side pressure adjustment can be achieved, and wide application is recommended.

Description

technical field [0001] The invention belongs to the technical field of oil seal (F16J15 / 32), and in particular relates to a rubber oil seal and a pressure sealing device thereof. Background technique [0002] Oil seal (oil seal) is the customary title of general seals, simply put, it is the seal of lubricating oil. It is a mechanical element used to seal grease (oil is the most common liquid substance in the transmission system, and also generally refers to the general liquid substance). It isolates the parts that need to be lubricated from the output parts in the transmission parts, and prevents fluid or solid Particles leak from the joint of the device, and prevent external impurities, such as dust, moisture, oil, etc., from invading the internal parts of mechanical equipment. It is used to isolate the oil chamber from the outside world, seal oil inside, and prevent dust outside , Widely used in household appliances, automobile transmitters, chemical industry and many oth...
