Abstract
The utility model relates to an outer ring of a bearing; a roller path is arranged at the inner side of the outer ring of the bearing; a roller path bus of the roller path on an axial section is a circular arc which is raised toward the center of the bearing; and the radius of the circular arc is 1000mm to 5000mm. The utility model also relates to the bearing which comprises the outer ring and the roller path on the outer ring; the roller path bus of the roller path of the outer ring on the axial section is the circular arc which is raised toward the center of the bearing so as to avoid the stress among both ends of a roller and the roller path when the bearing runs at a high speed, thereby reducing the friction between the both ends of the roller and the roller path, lowering the noise, maintaining the rotation stability of bearing and prolonging the service life of the bearing.
Description
Technical field
The utility model relates to a kind of bearing outer ring and has the bearing of this outer ring, particularly a kind of roller bearing outer ring and have the roller bearing of this outer ring.
Background technique
Bearing is one of parts commonly used in the modern production equipment, and roller bearing often is widely used in the middle of all kinds of industrial machines such as motor, lathe, oil, milling train handling machinery.Because roller bearing rolling element and the friction of lasso rib are little, be suitable for high speed, limit rotation, the structural design of the outer ring raceway of general roller bearing is lineal shape or arc domatic for its raceway bus, when the axle of roller bearing runs up, increased the stress of bearing outer ring ball track two ends rollers, roller and raceway are subjected to the influence of normal axle around curvature easily, thereby cause roller two ends and raceway friction greatly, not only can produce big noise, also can influence bearing working life.
The model utility content
The technical problems to be solved in the utility model is: occur easily in the existing roller bearing raceway structure because of normal axle produces the deficiency that stress is concentrated problems such as causing noise is big, bearing life shortening around the influence of curvature in order to overcome, the utility model provides a kind of roller bearing outer ring and has the roller bearing of this outer ring.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of bearing outer ring, and the inboard of bearing outer ring is provided with raceway, and the raceway bus of raceway on axial section is the circular arc to the bearing centre projection.
As preferably, radius of arc is 1000mm～5000mm.
A kind of bearing comprises the raceway on bearing outer ring and the outer ring, and the raceway bus of the raceway of bearing outer ring on axial section is the circular arc to the bearing centre projection.
As preferably, radius of arc is 1000mm～5000mm.
The beneficial effects of the utility model are, a kind of bearing outer ring of the utility model and have the bearing of this outer ring, the raceway bus of the raceway of bearing outer ring on axial section is the circular arc to the bearing centre projection, avoid bearing stress between roller two ends and the raceway when running up, thereby reduce friction between the two, reduce noise, keep the stable of bearing rotation, improve bearing working life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the axial section structural representation of the utility model bearing.
Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
Among the figure 1, bearing outer ring, 11, raceway, 12, the raceway bus, 2, roller.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, the axial section structural representation of the utility model bearing.A kind of bearing outer ring, the inboard of bearing outer ring 1 is provided with raceway 11, and the raceway bus 12 of raceway 11 on axial section is the circular arc to the bearing centre projection, and radius of arc is 1000mm～5000mm.A kind of bearing comprises the raceway 11 on bearing outer ring 1 and the outer ring, and the raceway bus 12 of the raceway 11 of bearing outer ring 1 on axial section is the circular arc to the bearing centre projection, and radius of arc is 1000mm～5000mm.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
