After adopting technique scheme, the beneficial effect that the utlity model has is:
The described full-complement cylinder roller bearing that has dustproof construction;
1. realize loading to greatest extent roller in outer, between the inner ring raceway, make bearing theory bearing capacity perform to the limit.
2. the oil duct of the oil duct of outer ring, inner ring and slope are for the storage of grease provides the space.
3. dustproof cover structure has sealed grease-filled space, has stoped external agency to enter in the bearing; Gossamery dust cover, the maximized packing space that grease is provided.
4. the metallic material dust cover can be good at heat radiation, and the utility model has improved the bearing working performance greatly, has prolonged bearing life, has saved the bearing user cost.
Description of drawings
Fig. 1 is an assembly structure schematic representation of the present utility model.
Among the figure: 1, outer ring; 2, inner ring; 3, cylindrical roller; 4, back-up ring; 5, dust cover; 6, raceway; 7, rib; 8, oil duct; 9, slope.
Embodiment
With reference to the following examples, can explain the utility model in more detail; But should be noted that the utility model is not limited to following embodiment.
The full-complement cylinder roller bearing that has dustproof construction as shown in Figure 1 comprises outer ring 1, inner ring 2, cylindrical roller 3, back-up ring 4, dust cover 5; Cylindrical roller 3 is installed in outer ring 1, the inner ring 2 corresponding part raceways 6, loads full whole zone; 1 internal diameter middle part in outer ring is set to cylindrical raceway 6, and 1 internal diameter both sides, outer ring are set to rib 7, and described rib 7 is provided with oil duct 8 with the joint of raceway 6, and described rib 7 is provided with groove near the end, and rib 7, raceway 6, outer ring 1 are set to one; Inner ring 2 external diameters middle parts is set to the cylindrical raceway 6 corresponding with outer ring 1, and inner ring 2 external diameters one side is provided with rib 7, opposite side is provided with the axial displacement that back-up ring 4 has limited cylindrical roller 3, and the internal diameter of back-up ring 4 is identical with the internal diameter of inner ring 2, and the width that back-up ring 4 adds inner ring 2 is equal to outer ring 1 width; Described raceway 6 one ends are provided with oil duct 8, the other end is provided with the slope 9 of drawing in to inner ring 2 axle center, and rib 7, raceway 6, inner ring 2 are set to one; Loop configuration dust cover 5 is provided with respectively in the described bearing face torus space, and a plurality of crimpings of the uniform setting of dust cover 5 external diameters and the groove fit of outer ring 1, dust cover 5 uses the superior carbon steel metallic material of heat-conducting property, the heat dissipation that helps reducing dust cover 5 thickness as far as possible and then increase grease-filled amount, produce can be timely and effectively with bearing working the time
Since cylindrical roller 3 in the outer ring 1, the contact of inner ring 2 raceways 6 is the line contact, and the quantity of cylindrical roller 3 maximizes, therefore under the prerequisite that bearing size does not increase, its theoretical bearing capacity promotes; The raceway 6 of inner ring 2 is designed to plus tolerance, promptly slightly is wider than cylindrical roller 3, to guarantee the normal rotation of cylindrical roller 3; Main load during bearing working is radial load, is born by cylindrical roller 3 and raceway 6, inevitably can produce simultaneously axial secondary load, and described thrust load is born by back-up ring 4 and can not had influence on dust cover; When bearing dispatches from the factory, fill up grease in advance in the interval that outer ring 1, inner ring 2, back-up ring 4, dust cover 5 form, the slope 9 of oil duct 8 and inner ring 2, for the storage of grease provides new space and the mobile passage that provides of grease is provided, even if grease partly leaks, and the greases in the oil duct 8 are difficult for leaking, make lubricated permanently effective, for bearing provides good lubricating condition, improved the operating mode in bearing working interval, effectively prolonged the working life of bearing.
The utility model efficiently solves the problem that the bearing working interval is isolated from the outside by dust cover 5 and the method that full-complement cylinder roller 3 combines, and has strengthened bearing load carrying capacity, has prolonged the working life of bearing, helps wideling popularize in Production of bearing enterprise.
