Abstract
The utility model discloses an oil seal capable of overcoming axial runout. The oil seal comprises a peripheral side part (1). A metal framework (2) is wrapped by the peripheral side part (1), and a circle of suspending part (3) is arranged inside a circumference defined by the peripheral side part (1). An auxiliary lip (4) and a main lip (5) are integrally formed on the inner wall of the suspending part (3), a lip opening (6) is formed between the auxiliary lip (4) and the main lip (5), and the position, corresponding to the auxiliary lip (4), of the suspending part is connected with the peripheral side part (1) through an elastic retractable body (7). The oil seal can overcome gaps produced by axial runout, and the problem that the oil seal leaks due to axial runout is completely solved. The oil seal has the advantages of being ingenious in design, simple in structure, reliable in performance, easy to transform, low in transformation cost and the like.
Description
Technical field
The utility model relates to a kind of Sealing, particularly a kind of oil sealing that can overcome axial runout.
Background technique
Oil sealing is the mechanical component of oil sealing (oil is modal liquid substance in the transmission system), and the lubricant oil that limits in the bearing spills on the one hand; On the other hand, prevent that silt, dust, aqueous vapor etc. are in outer intrusion bearing.Because bearing all the nature gap can occur after using certain hour, along with the circumference of axle rotatablely moves, axle can produce a kind of axial runout, easily produces the slit between axle and oil sealing thus, causes oil sealing to leak.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of can overcome axial runout, prevents the oil sealing that leaks.
The technical solution of the utility model is as follows: a kind of oil sealing that overcomes axial runout, comprise all sidepieces (1), in all sidepieces (1), be enclosed with metal frame (2), be provided with a circle hovering portion (3) in the circumference that described all sidepieces (1) surround, be formed with secondary lip (4) and main lip (5) on the inwall of this hovering portion (3), be lip (6) between secondary lip (4) and the main lip (5), the position of the described hovering corresponding secondary lip of portion (4) is connected with all sidepieces (1) by elastic telescopic body (7).
Adopt above technological scheme, because the elastic telescopic body has good scalability, like this under the effect of elastic telescopic body, hovering portion can adapt to the axial runout of axle together with the major-minor lip, and can compress or expand along with beating of axle, thereby avoided because axial runout produces the slit, thoroughly solved the oil sealing leakage problem that produces because of the axle jumping, reliability and the working life of having guaranteed oil sealing.
Described elastic telescopic body (7) is circle " U " type groove.Above Mechanical Builds is simple, is easy to processing and fabricating, and stretchability is good, can further improve the sealing of oil sealing.
For the ease of production, and reduce production costs, described all sidepieces (1), secondary lip (4), main lip (5) and elastic telescopic body (7) are by the rubber injection sulfidization molding.
As preferably, described lip (6) is circle " V " type groove.
Be set with metal spring (8) in the position of the corresponding main lip of described hovering portion (3) (5).Metal spring plays a part to tighten up, with the sealing of further raising oil sealing.
Beneficial effect: the utility model can overcome the slit that produces because of axial runout, jumps the oil sealing leakage problem that produces thereby thoroughly solved because of axle, has characteristics such as design is ingenious, simple in structure, reliable performance, transformation is easy, reforming cost is low.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utlity model has all sidepieces 1, this in week sidepiece 1 by the rubber injection sulfidization molding, in all sidepieces 1, be enclosed with metal frame 2, the moulding of metal frame 2 and production technology are prior art, do not give unnecessary details at this.Being provided with a circle hovering portion 3 in the circumference that described all sidepieces 1 surround, being formed with secondary lip 4 and main lip 5 on the inwall of this hovering portion 3, is lip 6 between secondary lip 4 and the main lip 5, and this lip 6 is preferably circle " V " type groove.The position of the corresponding secondary lip 4 of described hovering portion is connected as a single entity by elastic telescopic body 7 and all sidepieces 1, and elastic telescopic body 7 is preferably circle " U " type groove.Certainly, as the replacement that is equal to, elastic telescopic body 7 also can be selected other moulding for use, as long as can realize good fore and aft motion.Position at described hovering portion 3 corresponding main lips 5 is set with metal spring 8.
Claims (5)
1. oil sealing that overcomes axial runout, comprise all sidepieces (1), in all sidepieces (1), be enclosed with metal frame (2), be provided with a circle hovering portion (3) in the circumference that described all sidepieces (1) surround, be formed with secondary lip (4) and main lip (5) on the inwall of this hovering portion (3), be lip (6) between secondary lip (4) and the main lip (5), it is characterized in that: the position of the described hovering corresponding secondary lip of portion (4) is connected with all sidepieces (1) by elastic telescopic body (7).
