Abstract
Description
Technical Field
[0001] The utility model relates to a tapered hollow cylindrical roller bearing. Background Art
[0002] Cylindrical roller bearings are widely used in the major equipment machinery industry, especially large cylindrical roller bearings are used in wind power, steel mills, ships and other fields. The large bearings are complicated to process due to the large size of the finished bearings and parts. Considering the hardenability of the material during heat treatment, special grades of bearing steel are usually used, which increases the cost. In addition, for large-sized rollers, their weight increases and the processing becomes more difficult. Large-diameter rollers cannot be hardened with conventional materials due to their large wall thickness. The material needs to be improved to improve the hardenability, which increases the material cost. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model provides a tapered hollow cylindrical roller bearing, the roller of which is lighter in weight, more conducive to hardening, and has a good use effect.
[0004] To achieve the above object, the utility model provides a tapered hollow cylindrical roller bearing, comprising an inner ring, an outer ring and a cage arranged between the inner ring and the outer ring, wherein a roller is rotatably arranged on the cage, and a through groove is arranged on the roller, wherein the through groove is arranged in a tapered structure, and the taper of the tapered structure is 5° to 10°.
[0005] The beneficial effect of such an arrangement is that, by arranging the through groove, the dead weight of the roller can be effectively reduced, and part of the lubricating oil flows in through the large end of the tapered hollow groove and flows out through the small end of the tapered hollow groove. Since the cross-sectional area through which the lubricating oil flows is reduced, the flow rate of the lubricating oil can be increased, thereby improving the heat dissipation effect inside the roller, so that the finished cylindrical roller bearing has lightweight and low temperature rise performance, thereby improving product competitiveness.
[0006] As a further configuration of the present invention, adjacent rollers are arranged in opposite directions.
[0007] The beneficial effect of such arrangement is that such arrangement and such layout make the weight distribution of the structure more reasonable, improve the stability of the structure in use, and have a good use effect.
[0008] As a further configuration of the utility model, the through groove is respectively provided with a first slot and a second slot on the two end faces of the roller, the diameter of the first slot is smaller than that of the second slot, and the retaining frame includes a baffle covering the first slot and the second slot, and the diameter of the first slot and the second slot is larger than the width of the baffle.
[0009] The beneficial effect of such arrangement is that such arrangement makes the structure more convenient for lubricating oil to pass through, increases the fluidity of the lubricating oil, and has a good use effect.
[0010] As a further configuration of the utility model, an annular groove is provided on the retaining frame along the circumference of the roller.
[0011] The beneficial effect of such arrangement is that such arrangement makes it easier for the lubricating oil to circulate, effectively promotes the heat dissipation of the roller, and has a good use effect. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 It is a structural schematic diagram of an embodiment of the utility model. DETAILED DESCRIPTION
[0013] The utility model of the tapered hollow cylindrical roller bearing is implemented as follows Figure 1 As shown: it includes an inner ring 1, an outer ring 2 and a retaining frame 4 arranged between the inner ring 1 and the outer ring 2, the retaining frame 4 is rotatably provided with a roller 3, the roller 3 is provided with a through groove 31, the through groove 31 is arranged in a conical structure, and the taper of the conical structure is 10°. The beneficial effect of this arrangement is: in this way, the dead weight of the roller 3 can be effectively reduced by arranging the through groove 31, and part of the lubricating oil flows in through the large end of the conical hollow groove and flows out through the small end of the conical hollow groove. Since the cross-sectional area through which the lubricating oil flows is reduced, the flow rate of the lubricating oil can be increased, thereby improving the internal heat dissipation effect of the roller 3, so that the finished cylindrical roller 3 bearing has lightweight and low temperature rise performance, thereby improving product competitiveness.
[0014] As a further configuration of this embodiment, adjacent rollers 3 are arranged in opposite directions. The beneficial effect of such configuration is that such configuration and such layout make the weight distribution of the structure more reasonable, improve the stability of the structure in use, and have a good use effect.
