Description
Technical field
The utility model relates to field of bearings, particularly a kind of roller bearing.
Background technique
Roller bearing is that outer ring adopts the thicker full-complement cylinder roller bearing of collar wall, and the outer diametric plane of roller has cylindrical and arc, can coordinate with roller surface according to use occasion design.But, existing roller bearing have otherwise its lubrication effect poor, or its sealing is poor, thereby its use occasion is restricted, and can not satisfy the demand.
Summary of the invention
The purpose of this utility model: in order to overcome the defect of prior art, the utility model provides a kind of roller bearing, and its good airproof performance, high lubricating effect are simple in structure, installation, convenient disassembly.
The technical solution of the utility model: a kind of roller bearing, include outer ring, inner ring, roller, between described outer ring, inner ring, be provided with raceway, described roller is placed in raceway, it is characterized in that: described inner ring two ends are provided with back-up ring, and described two ends, outer ring all extend to outside inner ring, between the outer wall of described back-up ring and outer ring, be provided with spring sheet, described outer ring is provided with outer lubrication hole, and described inner ring is provided with interior lubrication hole, and described outer lubrication hole, interior lubrication hole extend in raceway.
Adopt technique scheme, by the back-up ring that arranges and the spring sheet that arranges, make its good sealing effect between the outer wall of back-up ring and outer ring; The outer lubrication hole, the interior lubrication hole that arrange, can provide lubricant oil to bearing, thereby make its high lubricating effect, therefore, the roller bearing of this structure, its good airproof performance, high lubricating effect, simple in structure, installation, convenient disassembly.
Further setting of the present utility model: the external diameter of described back-up ring is greater than the external diameter of inner ring, the inward at both ends side of described outer ring is all extended with and convexes to form the outer ring that cross section profile is down " U " font, and described spring sheet is arranged between the projection on back-up ring outer wall and outer ring.
Adopt above-mentioned further setting, can prevent well that it from coming off so that the axially locating of roller is more reliable like this, by the projection on back-up ring, outer ring, carry together the axial force that roller produces, can extend the working life of bearing.
Further setting more of the present utility model: on described projection, back-up ring, corresponding position is provided with draw-in groove, and described spring sheet is arranged in described draw-in groove.
Adopt above-mentionedly further to arrange, the draw-in groove of setting, can be so that the location of spring sheet be reliable again, and the spring sheet set-up mode of this structure, makes that it is installed, convenient disassembly.
Further setting more of the present utility model: be provided with some groups of rollers in described raceway, two adjacent groups roller is conflicted mutually, and described outer lubrication hole, interior lubrication hole extend to two adjacent groups roller conflicting position in raceway.
Adopt above-mentioned further setting again, the bearing capacity that some groups of rollers can improve bearing is set, by outer lubrication hole, interior lubrication hole being extended to two adjacent groups roller conflicting position in raceway, like this can be so that two adjacent groups roller to be evenly lubricated, the lubrication effect of bearing further improves.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is I part partial enlarged drawing in Fig. 1.
Embodiment
As shown in Figure 1, 2, a kind of roller bearing, include outer ring 1, inner ring 2, roller 3, between described outer ring 1, inner ring 2, be provided with raceway 5, described roller 3 is placed in raceway 5, described inner ring 2 two ends are provided with back-up ring 4, described 1 two ends, outer ring all extend to outside inner ring 2, between the outer wall of described back-up ring 4 and outer ring 1, be provided with spring sheet 6, described outer ring 1 is provided with outer lubrication hole 11, described inner ring 2 is provided with interior lubrication hole 21, and described outer lubrication hole 11, interior lubrication hole 21 extend in raceway 5.By the back-up ring 4 that arranges and at the spring sheet 6 of setting between the outer wall of back-up ring 4 and outer ring 1, make its good sealing effect; The outer lubrication hole 11, the interior lubrication hole 21 that arrange, can provide lubricant oil to bearing, thereby make its high lubricating effect, therefore, roller 3 bearings of this structure, its good airproof performance, high lubricating effect, simple in structure, installation, convenient disassembly.
In the utility model specific embodiment, the external diameter of described back-up ring 4 is greater than the external diameter of inner ring 2, the inward at both ends side of described outer ring 1 is all extended with the outer ring 1 that protruding 12 Formation cross-section profiles are down " U " font, and described spring sheet 6 is arranged between the projection 12 on back-up ring 4 outer walls and outer ring 1.Can prevent well that it from coming off so that the axially locating of roller 3 is more reliable like this, by the projection 12 on back-up ring 4, outer ring 1, carry together the axial force that roller 3 produces, can extend the working life of bearing.
In the utility model specific embodiment, on described projection 12, back-up ring 4, corresponding position is provided with draw-in groove 13,41, and described spring sheet 6 is arranged in described draw-in groove 13,41.The draw-in groove 13,41 arranging, can be so that the location of spring sheet 6 be reliable, and spring sheet 6 set-up modes of this structure, make that it is installed, convenient disassembly.
In the utility model specific embodiment, in described raceway 5, be provided with two groups of rollers 3, every group of roller 3 includes a plurality of 3, two groups of rollers 3 of roller that axially arrange around inner ring 2 and mutually conflicts, and described outer lubrication hole 11, interior lubrication hole 21 extend to two groups of roller 3 conflict positions in raceway 5.The bearing capacity that two groups of rollers 3 can improve bearing is set, by outer lubrication hole 11, interior lubrication hole 21 being extended to two groups of roller 3 conflict positions in raceway 5, like this can be so that two groups of rollers 3 to be evenly lubricated, the lubrication effect of bearing further improves.
