Description
[technical field]
The utility model relates to the technical field of Bearing fittings, particularly the technical field of internal diameter three lip band glue dust cover and lips band glue back-up ring composite structure.
[background technique]
Automobile bearing is indispensable for the normal operation of automobile, and the normal work of bearing is very important, and bearing seal can available protecting bearing, prevents bearing contaminated, simultaneously the normal lubricating bearings of lubricant grease of available protecting inside.The modern bearing seal used is varied; but can not the normal work of available protecting bearing; structural design is unreasonable; do not have the effect of sealing; and the bearing seal structure of majority is single; sealing configuration easily damages, and makes the working environment of bearing be broken ring, reduces the working life of bearing.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, a kind of internal diameter three lip band glue dust cover and lips band glue back-up ring composite structure are proposed, the grease in bearing can be made not easily excessive, and from external contaminants and dust are difficult to invade inside, improve the working life of bearing.
For achieving the above object, the utility model proposes a kind of internal diameter three lip band glue dust cover and lips band glue back-up ring composite structure, comprise three lip adhesive tape skeletons, lips adhesive tape skeleton, three lip adhesive tapes, lips adhesive tape, described three lip adhesive tapes coordinate with three lip adhesive tape skeleton gluings, described lips adhesive tape coordinates with lips adhesive tape skeleton gluing, and three lip adhesive tapes and lips adhesive tape cooperation place form sealing strip.
As preferably, described three lip adhesive tapes and three lip adhesive tape skeleton gluing cooperation places are provided with sealing surface, and three lip adhesive tapes are sealing lip limit on sealing strip place structure has, and three lip adhesive tapes are also provided with sealing lip, enables path portion effective sealing in bearing.
As preferably, described lips adhesive tape skeleton is provided with mating edge, and lips adhesive tape has lower seal lip limit in sealing strip place structure, and lips adhesive tape is also provided with horizontal seal lip, and multi-sealed setting ensures that sealing puts in place.
The beneficial effects of the utility model: the utility model is by coordinating lips adhesive tape with lips adhesive tape skeleton gluing, three lip adhesive tapes and lips adhesive tape cooperation place form sealing strip, make the grease in bearing not easily excessive, from external contaminants and dust are difficult to invade inside, improve the working life of bearing; Described three lip adhesive tapes and three lip adhesive tape skeleton gluing cooperation places are provided with sealing surface, and three lip adhesive tapes are sealing lip limit on sealing strip place structure has, and three lip adhesive tapes are also provided with sealing lip, enables path portion effective sealing in bearing; Described lips adhesive tape skeleton is provided with mating edge, and lips adhesive tape has lower seal lip limit in sealing strip place structure, and lips adhesive tape is also provided with horizontal seal lip, and multi-sealed setting ensures that sealing puts in place.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
