Abstract
The utility model discloses an universal joint axle oil blanket mainly includes axle oil blanket etc. and the suit bearing is gone up to four journals of cross axle, and installation axle oil blanket seals between bearing oral area and the cross axle, and the axle oil blanket is inlayed by the outside and is had the oil blanket skeleton, and the axle oil blanket leans on the bearing side to be equipped with lip A and lip B, and the bearing oral area is the planar structure by the circular arc transition, and lip A, lip B are sealed with circular arc, plane cooperation respectively, and the space between lip A, the lip B forms the oil storage tank. The utility model adopts the multi-lip design, the outer lip prevents the intrusion of external muddy water, the inner lip prevents the overflow of internal grease, the sealing performance of the product is improved, and the service life is prolonged; the U-shaped framework is embedded in the shaft oil seal, so that the strength of the oil seal is improved, and the shaft oil seal has better anti-aging and anti-deformation capacity; an oil storage tank is designed between the lips of the shaft oil seal to store oil, so that early wear failure caused by dry friction of the lips is prevented; the sealing effect is good, the service life of the product is long, and better market space can be brought.
Description
Technical Field
The utility model relates to a field of universal joint, concretely relates to universal joint axle oil blanket.
Background
The steering universal joint in the prior art generally comprises a cross shaft 1, a primary shaft oil seal 21 and a bearing 3, the primary shaft oil seal 21 in the prior art is simple in structural design, the upper opening of the bearing 3 is sealed to form a single-lip opening, the sealing effect is poor, external muddy water is easy to intrude, and early failure is caused. Meanwhile, the original shaft oil seal 21 is not embedded with a framework, and is easy to age, deform and lose efficacy after long-time use. The existing steering universal joint has short service life and low product competitiveness due to the reasons.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide a universal joint axle oil blanket.
The purpose of the utility model is accomplished through following technical scheme: the universal joint shaft oil seal mainly comprises a cross shaft, a shaft oil seal, a bearing, an oil seal framework, a lip A, a lip B, an oil storage tank, an arc and a plane, wherein the bearing is sleeved on four shaft necks of the cross shaft, the shaft oil seal is installed between a bearing opening and the cross shaft to be sealed, the shaft oil seal is embedded into the oil seal framework by the outer side, the lip A and the lip B are arranged on the shaft oil seal by the bearing side, the bearing opening is of a plane structure transited by the arc, the lip A and the lip B are respectively matched and sealed with the arc and the plane, and the oil storage tank is formed in the space between the lip A and the lip B.
The oil seal framework is U-shaped.
The oil seal framework is formed by low-carbon steel through punching.
The utility model has the advantages that: the utility model adopts the multi-lip design, the outer lip prevents the intrusion of external muddy water, the inner lip prevents the overflow of internal grease, the sealing performance of the product is improved, and the service life is prolonged; the U-shaped framework is embedded in the shaft oil seal, so that the strength of the oil seal is improved, and the shaft oil seal has better anti-aging and anti-deformation capacity; an oil storage tank is designed between the lips of the shaft oil seal to store oil, so that early wear failure caused by dry friction of the lips is prevented; the sealing effect is good, the service life of the product is long, and better market space can be brought.

Description of reference numerals: the cross shaft 1, the shaft oil seal 2, the bearing 3, the oil seal framework 4, the lip A5, the lip B6, the oil storage tank 7, the arc 8, the plane 9 and the original shaft oil seal 21.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example (b): as shown in the attached drawing, the universal joint shaft oil seal mainly comprises a cross shaft 1, a shaft oil seal 2, a bearing 3, an oil seal framework 4, a lip A5, a lip B6, an oil storage tank 7, an arc 8 and a plane 9, wherein the bearing 3 is sleeved on four shaft necks of the cross shaft 1, the shaft oil seal 2 is installed between the mouth of the bearing 3 and the cross shaft 1 for sealing, the oil seal framework 4 is embedded on the outer side of the shaft oil seal 2, and the oil seal framework 4 is U-shaped. Oil blanket skeleton 4 is low carbon steel stamping forming, and the part is inlayed and can improve 2 bulk strength of axle oil blanket after inside in rubber, prevents that axle oil blanket 2 from warping. The shaft oil seal 2 is provided with a lip A5 and a lip B6 close to the bearing 3, the opening of the bearing 3 is of a plane 9 structure transited by an arc 8, the lip A5 and the lip B6 are respectively matched and sealed with the arc 8 and the plane 9, the lip A5 prevents external muddy water from entering, the lip B6 prevents grease inside the bearing 3 from overflowing, an oil storage tank 7 is formed in the space between the lip A5 and the lip B6, the oil storage tank 7 is used for storing grease, and the dry friction between the lip A5 and the lip B6 is prevented.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
