Roller between circle, such assembling unit structure is excessively complicated, space-consuming is larger.
The content of the invention
In view of the shortcomings of the prior art, the utility model provides a kind of idle pulley bearing with automobile engine, its
Directly using mandrel as its inner ring, and its outer ring is substituted idle pulley to use, so as to be effectively simplified product structure, substantially reduce
The space-consuming of product.
To achieve the above object, the utility model provides the idle pulley bearing in a kind of automobile engine, including mandrel, outer
Circle and roller, described outer ring are sleeved on outside mandrel, and described roller is installed between mandrel and outer ring, the mandrel and outer ring
Between be additionally provided with sealing device, and the sealing device is correspondingly located at the axial both sides of roller, and described sealing device includes
Sealing ring and metal outer frame frame, the metal outer frame frame are the Jiong word shape structure of radial outer end closing and radial inner end opening, outside
The slot of the radial outer end insertion for metal outer frame frame is correspondingly provided with circle, is additionally provided with the middle part of the radial outer end of metal outer frame frame
The groove being radially-inwardly recessed, the steel ball being in contact with outer ring is equiped with described groove, sealing ring is installed in metal outer frame
In frame, the radial inner end of sealing ring is in contact with mandrel, between the radial outer end of sealing ring and the radial outer end of metal outer frame frame
It is provided with spring.
The beneficial effects of the utility model are：Using said structure, due to the roller be installed directly in mandrel with it is outer
Between circle, therefore the mandrel can be directly as the inner ring of bearing, and the alternative original idle pulley in the outer ring of bearing uses,
So as to be effectively simplified product structure, the space-consuming of product is substantially reduced.Meanwhile described sealing device using sealing ring and
Metal outer frame frame is formed, and metal outer frame frame is wrapped in outside sealing ring, so as to play good flameproof effect；And sealing ring
Radial inner end is in contact with mandrel, is provided with spring between the radial outer end of sealing ring and the radial outer end of metal outer frame frame, then
Sealing wear face can be supplemented well, so as to greatly promote the sealing property of bearing under the action of the spring；In addition, in metal
The groove being radially-inwardly recessed is additionally provided with the middle part of the radial outer end of outer framework, and is equiped with described groove and connects with outer ring
Tactile steel ball, then outer ring is contributed to preferably to be rotated relative to mandrel.
The utility model can be further arranged to the spring locator card dress on the surface of the recesses.In this way, can be right
Spring forms good stationary positioned.
The utility model may further be provided as the radial outer end of the metal outer frame frame and be plugged with it outer
It is swallowtail-shaped structure to enclose slot.Assembled in this way, metal outer frame frame can be enable to form reliably positioning with outer ring.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 A portions enlarged drawing.
