Abstract
The utility model relates to a double-row cylindrical roller bearing which comprises a roller, an outer ring and an inner ring, wherein the outer ring is step-shaped, two rows of single raceway grooves are formed in an inner hole of the outer ring, a cage is arranged between the inner ring and the outer ring, and the inner ring is provided with two parallel oil injection holes along the radial direction thereof. According to the double-row cylindrical roller bearing disclosed by the utility model, radial and axial bearing forces are added, and a lubrication effect is also added, therefore, the frictional heating and the energy loss are reduced, the service life of the bearing is prolonged, the rotating speed of the bearing is improved, and the working efficiency of the bearing is greatly improved.
Description
Technical field
The utility model relates to a kind of Biserial cylindrical roller bearing.
Background technique
In industries such as automobile, milling train, mine, metallurgy, plastics machineries; can require to have supporting design bearing; often can use roller bearing, the overwhelming majority adopts single row roller bearing, and this airframe bearing bearing capacity is low; install and use loaded down with trivial details; and in use, can cause bearing temperature to raise, the early fatigue phenomenon occurs, do not meet need of work; and bearing also bears bigger axial load when bearing bigger radial load, so phenomenon such as often take place that bearing roller breaks.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of bigger radial and axial load, safe and simple Biserial cylindrical roller bearing of bearing is provided.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of Biserial cylindrical roller bearing, have roller, outer ring and inner ring, described outer ring is ladder-type, offer the two raceway grooves of itemizing in the endoporus of outer ring, be provided with retainer between inner ring and the outer ring, inner ring radially is provided with two parallel oil holes.
Further, described two row roller opposite ends offer axis hole, and retainer has the pin that cooperates with axis hole.
Further, between the two ends of the working surface of described roller and the section be arc transition.
The beneficial effects of the utility model are: the utility model has increased radial and axial strength, has increased lubrication simultaneously, reduces frictional heating and energy loss, has improved working life and the rotating speed of bearing, has improved the working efficiency of bearing greatly.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
1. retainers among the figure, 2. roller, 3. outer ring, 4. inner ring, 5, the raceway groove.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic representation that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of Biserial cylindrical roller bearing as shown in Figure 1, have roller 2, outer ring 3 and inner ring 4, outer ring 3 is ladder-type, offer the two raceway grooves 5 of itemizing in 3 endoporus of outer ring, be provided with retainer 1 between inner ring 4 and the outer ring 3, inner ring 4 radially is provided with two parallel oil holes, and two row rollers, 2 opposite ends offer axis hole, retainer 1 has the pin that cooperates with axis hole, is arc transition between the two ends of the working surface of roller 2 and the section.
Above-mentioned mode of execution only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed in the protection domain of the present utility model.
