Abstract
The utility model discloses an end surface-positioned and assembled wholly-installed muddy water-resistant oil seal, which comprises an inner oil seal and an outer oil seal, wherein the inner oil seal comprises an inner support frame and an inner elastic sealing body, and the cross section of the inner support frame has the structure that the outer surface of the inner support frame is bonded with the inner elastic sealing body; the outer oil seal comprises an outer support frame and an outer elastic sealing body; the upper end part of the outer support frame is packed and bonded by the outer elastic sealing body, the outer elastic sealing body is provided with an extension part, the extension part is provided with a main lip opening, the back side of the main lip opening is provided with a spring, and two diagonal lower assistant lips and a dustproof lip are arranged under the main lip opening; and a dustproof tray is arranged under the inner oil seal and the outer oil seal, and the outer edge of the dustproof tray and a grasping edge at the lower end of the outer support frame form a whole. The oil seal is installed in a seat hole and a shaft to be capable of avoiding shifting or inclining and being unavailable; and the rigidity of a limitation structure of the end surface is increased to prevent the muddy water from entering the oil seal.
Description
Technical field
The utility model relates to a kind of oil sealing, especially relates to a kind of end face location composite entity anti-muddy water oil sealing is installed.
Background technique
At present, combined integrate is installed anti-muddy water oil sealing (referring to accompanying drawing 1) after oil sealing is packed a hole into, because axle is an interference fit with the oil sealing endoporus, oil sealing on the present hole easily will be installed during installation shaft, impact displacement or run-off the straight vertically, oil sealing can not be worked on the normal position, cause oil sealing early failue or reduce working life.
The model utility content
The technical problems to be solved in the utility model provides a kind of end face location composite entity anti-muddy water oil sealing is installed; This oil sealing can prevent to assemble the oil sealing displacement that causes or tilt, and can effectively prevent the inefficacy that oil sealing causes because of assembling; And increased the anti-muddy water effect of oil sealing.
For solving the problems of the technologies described above, the utility model adopts following technological scheme, and it comprises inner oil seal and outer oil seal;
Support frame and interior elastic sealed body in described inner oil seal comprises, described interior support frame cross section is
Bonding interior elastic sealed body on the support frame outer surface in being somebody's turn to do;
Described outer oil seal comprises outer support frame and outer elastic sealed body; Described outer support frame upper end part is coated bonding by outer elastic sealed body, outer elastic sealed body is provided with extension part, this extension part is provided with main lip, and this main lip phase dorsal part is provided with spring, and this main lip below is provided with two the secondary lips in oblique below and a dust excluder lips; Described main lip and two secondary lips are crossed to win with the longitudinal inner surface of interior support frame and are cooperated; Described dust excluder lips is crossed to win with the horizontal internal surface of interior support frame and is cooperated;
Described outer support frame lower end, promptly the part that is not coated by outer elastic sealed body is provided with certain surplus, holds the limit with the outer edge of dustproof dish and is combined into one;
The outer oil seal below is provided with dustproof dish in described, and the outer edge of this dustproof dish is held the limit with outer support frame lower end and is combined into one.
Further, described interior support frame outer surface and the sulfuration of interior elastic sealed body are structure as a whole.
Further, described outer support frame is structure as a whole with the outer elastic sealed body partial vulcanization that coats on it.
Further, described inside and outside elastic sealed body adopts the rubber material.
Further, described inside and outside support frame adopts steel.
The utility model when reinstalling spool, produces displacement or tilts because fabricated structure can prevent oil sealing behind a hole of packing under the active force of axle, the assurance oil sealing is worked on the normal position, can effectively prevent oil seal failure; Simultaneously, the dustproof dish that end face increases both can increase the rigidity of end face limit structure, can prevent that again muddy water from entering oil sealing, had increased the anti-muddy water effect of oil sealing.

Fig. 1 is that existing combined integrate is installed anti-muddy water oil seal structure schematic representation;
Fig. 2 is the utility model structural representation.
Embodiment
In order to show substantive distinguishing features of the present utility model and remarkable progress, further specify mode of execution and effect with following indefiniteness embodiment.
Referring to shown in Figure 2, the utility model comprises inner oil seal 1 and outer oil seal 2;
Described outer oil seal 2 comprises outer support frame 21 and outer elastic sealed body 22; Described outer support frame 21 upper end parts are coated and fixed by outer elastic sealed body 22, outer elastic sealed body 22 is provided with extension part 23, this extension part 23 is provided with main lip 24, these main lip 24 phase dorsal parts are provided with spring 25, and these main lip 24 belows are provided with secondary lip 26, secondary lip 27 and the dust excluder lips 28 of oblique below; Described main lip 24 and two secondary lips 26,27 are crossed to win with the longitudinal inner surface of interior support frame 11 and are cooperated; Described dust excluder lips 28 is crossed to win with the horizontal internal surface of interior support frame 11 and is cooperated;
Described outer support frame 21 lower ends, promptly the part that is not coated by outer elastic sealed body 22 is provided with surplus 221, holds the limit with the outer edge of dustproof dish 3 and is combined into one;
Described inside and outside oil sealing 1,2 belows are provided with dustproof dish 3, and the outer edge of this dustproof dish 3 is held the limit with the lower end of outer support frame 21 and is combined into one.
