Description
Technical field
The utility model relates to automobile engine front end accessory transmission device field, particularly relates to a kind of automobile engine front end accessory transmission tensioner with water-tight device.
Background technique
In Chinese market, because the environment of road differs, a lot of regional traveling state of vehicle is poor, and vehicle is often paddled, and the mud splashed drops on stretcher bearing surface, infringement bearing, causes bearing failure to produce noise.
Model utility content
The utility model provides a kind of automobile engine front end accessory transmission tensioner with water-tight device, stretcher structural type is improved by adopting, increase belt wheel sealing cover and increase stretcher aluminum casting screening area, stop the direct contact bearing seal ring of a large amount of mud, reduce bearing failure ratio, have market prospects widely popularizing of the automobile engine front end accessory transmission tensioner with water-tight device.
For solving the problems of the technologies described above, the utility model provides a kind of automobile engine front end accessory transmission tensioner with water-tight device, intake into mud for preventing stretcher, comprise: tensioner arms, belt wheel, bearing, bolt, boss and lid, described belt wheel comprises end ring, described tensioner arms designs for labyrinth and comprises boss, described boss to be arranged in described tensioner arms and end ring described in part overlaid, described lid is arranged on the inner side of end ring and hides described bearing and described bolt, and described lid and described end ring are interference fit.
In the utility model preferred embodiment, the inner side of described end ring is provided with groove, the two ends groove described in screens respectively of described lid.
In the utility model preferred embodiment, described bolt is countersunk screw.
The beneficial effects of the utility model are: the utility model has with the automobile engine front end accessory transmission tensioner of water-tight device and reduces muddy water and invade bearing, avoid that the possibility that bearing failure produces noise, muddy water enters bearing reduces, degradation advantage relatively descend in bearing failure, has market prospects widely popularizing of the automobile engine front end accessory transmission tensioner with water-tight device.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of automobile engine front end accessory transmission tensioner one preferred embodiment with water-tight device of the present utility model.
Embodiment
Be clearly and completely described to the technological scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model is embodiment comprise:
A kind of water-tight device for automobile engine front end accessory transmission device, intake into mud for preventing stretcher, described stretcher comprises belt wheel 1, bearing 2, bolt 3, lid 4 and tensioner arms 5, and described belt wheel 1 comprises end ring 101, and tensioner arms 5 comprises boss 6 and 7.
Described boss 6 and 7 is arranged in described tensioner arms, and end ring 101 described in boss 6 part overlaid, form labyrinth; Described lid 4 is arranged on the inner side of end ring 101 and hides described bearing 2 and described bolt 3, and described lid 4 is interference fit with described end ring 101.
