Abstract
The utility model relates to a novel oil seal structure of a high-speed running part, which comprises a flange sleeve connected on a hollow shaft, wherein the flange sleeve is provided with a V-shaped oil seal and two framework oil seals, and the framework oil seals are positioned below the V-shaped oil seals; the framework oil seal is a double-lip framework oil seal; the framework oil seal is made of fluorine glue; the V-shaped oil seal and the framework oil seal are attached with a compression ring, a groove with the depth of 0.50 mm is formed in the plating surface of the compression ring, and chromium sesquioxide is plated in the groove. The utility model relates to a novel oil blanket structure at high-speed operation position, the during operation is chromium oxide coating and skeleton oil blanket friction all the time, and the cladding material is difficult for droing, and it is fine to move the friction effect, has improved the life of clamping ring, and the skeleton oil blanket is not fragile, and the material of skeleton oil blanket is the fluorine glue for the high speed and high temperature resistance performance of skeleton oil blanket promotes.
Description
Technical Field
The utility model relates to a novel oil blanket structure at high-speed operation position.
Background
The oil seal is a mechanical element for sealing oil, and separates a part needing lubrication in a transmission part from a force-applying part, so that the lubricating oil is prevented from leaking. The sealing elements for static sealing and dynamic sealing are called sealing elements. The framework oil seal is a typical representative of the oil seal, and the oil seal is generally referred to as the framework oil seal, and the framework is just like a steel bar in a concrete member, plays a role in reinforcing and enables the oil seal to keep shape and tension.
The framework oil seal and the compression ring form sealing, the thickness of a coating of the conventional compression ring is 0.10 mm, the coating is directly plated on the surface of the compression ring, the coating is thin and easy to fall off, the compression ring is easy to grind out a groove and burn the framework oil seal, and the service life of the compression ring is short; in addition, the conventional framework oil seal is made of nitrile rubber, and the high-speed and high-temperature resistance performance of the nitrile rubber is common. Therefore, an oil seal structure for a high-speed operation part with strong sealing stability, high-speed and high-temperature resistance and good dynamic friction effect is urgently needed at present.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned not enough, provide an oil blanket structure at the effectual high-speed operation position of sealing stability strong, resistant high-speed and high temperature, dynamic friction.
The purpose of the utility model is realized like this:
a novel oil seal structure of a high-speed operation part comprises a flange sleeve connected to a hollow shaft, wherein a V-shaped oil seal and two framework oil seals are arranged on the flange sleeve, and the framework oil seals are positioned below the V-shaped oil seals; the framework oil seal is a double-lip framework oil seal; the framework oil seal is made of fluorine glue; the V-shaped oil seal and the framework oil seal are attached with a compression ring, a groove with the depth of 0.50 mm is formed in the plating surface of the compression ring, and chromium sesquioxide is plated in the groove.
The utility model relates to a novel oil blanket structure at high-speed operation position have following advantage:
the utility model relates to a novel oil seal structure of a high-speed operation part, which is characterized in that a groove with the depth of 0.50 mm is arranged on the plating surface of a compression ring, chromium sesquioxide is plated in the groove, so that the plating layer is thicker, the chromium sesquioxide plating layer always rubs with a framework oil seal during working, the plating layer is not easy to fall off, the dynamic friction effect is very good, the service life of the compression ring is prolonged, and the framework oil seal is not easy to damage; the utility model relates to a novel oil blanket structure at high-speed operation position in the material of skeleton oil blanket be the fluorine and glue for the high-speed and high temperature resistance performance of resistant of skeleton oil blanket promotes.
Drawings
Fig. 1 is a cross-sectional view of the novel oil seal structure at the high-speed operation position of the present invention.
Fig. 2 is an enlarged schematic view of the frame oil seal of fig. 1.
Figure 3 is an enlarged schematic view of the pressure ring of figure 1.
In the figure: the hollow shaft 1, V type oil blanket 2, skeleton oil blanket 3, clamping ring 4, flange cover 5, slot 6.
Detailed Description
Referring to fig. 1 to 3, the utility model relates to a novel oil seal structure of high-speed operation part, comprising a flange sleeve 5 connected on a hollow shaft 1, wherein the flange sleeve 5 is provided with a V-shaped oil seal 2 and two framework oil seals 3, the framework oil seals 3 are positioned below the V-shaped oil seals 2, the framework oil seals 3 are double-lip framework oil seals, and the auxiliary lips can prevent external dust, impurities and the like from entering the interior of the machine; the framework oil seal 3 is made of fluorine rubber, so that the high-speed resistance and high-temperature resistance of the framework oil seal are enhanced; v type oil blanket 2 and framework oil blanket 3 go up the laminating have clamping ring 4, set up the slot 6 that the degree of depth is 0.50 millimeter on the plating layer face of clamping ring 4, it has chromium sesquioxide to plate in the slot 6 for the cladding material is thicker, and the during operation is chromium sesquioxide cladding material and the friction of framework oil blanket 3 all the time, and the cladding material is difficult for droing, and dynamic friction effect is fine.
