The beneficial effects of the utility model are that: through bearing inner race, inner circle, keep mutually supporting between ware and the roller, the effect that has realized roller and inner circle and kept ware area of contact to reduce, and then little, the high -speed purpose that the temperature is low, the noise is little that operates of frictional resistance when having reached the bearing operation.
Description
Technical field
This utility model relates to technical field of bearings, it particularly relates to a kind of single row roller bearing.
Background technology
Current single row roller bearing is extensive in the application in machine equipments of high speed and big load, its bearing many employings pyrite, nylon, three kinds of material holder of punching press, these three keeper produces high resistance to roller surface friction, temperature is high, noise is big, make roller surface can not well form oil film, cause bearing life to decline, improve the maintenance cost of equipment.
Therefore, develop a kind of single row roller bearing rational in infrastructure, that frictional resistance is little, the temperature that runs up is low, noise is little to become insider and need badly and solve the technical problem that.
Utility model content
The purpose of this utility model is to provide a kind of rational in infrastructure, frictional resistance is little, the temperature that runs up is low, noise is little single row roller bearing when running, and overcomes the deficiency of above-mentioned aspect in existing product.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of single row roller bearing, including bearing outer ring, inner ring, keeper and roller, described keeper is between outer ring and inner ring, the raceway both sides of described inner ring are provided with rib, and the inner side end of described inner ring rib is convex globoidal one, and described keeper circumference is provided with some evenly spaced pocket holes, described roller is cylindric, the end face at described roller two ends is cancave cambered surface, and described cancave cambered surface edge circumference is convex globoidal two, and described roller is positioned in pocket hole.
Further, it is provided with between described pocket hole and pocket hole and places restrictions on obstruct hurdle.
Further, described in place restrictions on obstruct width mouth two ends, hurdle width less than roller diameter, and width mouth width incrementally increases to middle direction.
Further, the convex globoidal two of described roller contacts with keeper.
Further, the cancave cambered surface of described roller contacts with the convex globoidal one inside inner ring rib.
The beneficial effects of the utility model are: by cooperating between bearing outer ring, inner ring, keeper and roller, achieve the effect that roller reduces with inner ring and keeper contact area, and then reach the purpose that when bearing runs, frictional resistance is little, the temperature that runs up is low, noise is little.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained, broadly fall into the scope of this utility model protection.
As Figure 1-5, according to a kind of single row roller bearing described in this utility model embodiment, including bearing outer ring 1, inner ring 2, keeper 4 and roller 3, described keeper 4 is between outer ring 1 and inner ring 2, the raceway both sides of described inner ring 2 are provided with rib 5, the inner side end of described rib 5 is convex globoidal 1, described keeper 4 circumference is provided with some evenly spaced pocket holes 7, described roller 3 is cylindric, the end face at described roller 3 two ends is cancave cambered surface 8, described cancave cambered surface 8 edge circumference is convex globoidal 29, and described roller 3 is positioned in pocket hole 7.Wherein, be provided with between described pocket hole 7 place restrictions on obstruct hurdle 10；Wherein, described in place restrictions on and intercept width mouth 11 width on hurdle 10 less than roller diameter, and width mouth 11 width incrementally increases to middle direction；Wherein, the convex globoidal 29 of described roller contacts with keeper 4；Wherein, the cancave cambered surface 8 of described roller contacts with the convex globoidal 1 inside inner ring rib.
Understand technique scheme of the present utility model for convenience, below by way of in specifically used mode, technique scheme of the present utility model is described in detail.
When actually used, convex globoidal 1 inside inner ring 2 raceway two ends rib 5 contacts with the cancave cambered surface 8 of roller 3 two ends end face, decreases contact area so that be reduced to present some friction from original face friction, noise and frictional resistance can be made to reduce exponentially, and the flexibility ratio of bearing increases exponentially.Keeper 4 circumference has some uniform pocket holes 7, and placing restrictions between pocket hole 7 and pocket hole 7 intercepts hurdle 10, and its width mouth 11 two ends width is less than cylindrical roller 3 diameter, and width mouth 11 two ends progressively expand to middle direction width.Cylindrical roller 3 is arranged in the pocket hole 7 of keeper 4, simply roller 3 two ends convex globoidal 29 contacts with keeper 4, roller 3 periphery does not contacts with keeper 4, so installation roller 3 and keeper 4 are loose fit, stop the keeper 4 frictional force to roller 3, make roller 3 surface form oil film well, decrease noise and resistance, improve the service life of bearing.
This utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but in its shape or structure, make any change; every have same as the present application or akin technical scheme, within all falling within protection domain of the present utility model.
