Description
Technical Field
The utility model relates to a roller bearing.
Background
In roller bearings, a cage is generally provided for supporting the rollers, and a seal ring is provided for sealing the interior of the roller bearing. However, in the existing roller bearing, the sealing ring and the retainer are arranged in a split manner, the retainer is usually erected on the aligned rollers, the sealing ring is clamped between the outer ring and the inner ring and keeps a certain gap with the retainer, but the split arrangement of the sealing ring and the retainer can cause the increase of manufacturing cost and the complexity of the assembly process and the difficulty of disassembly of the roller bearing, and the gap between the sealing ring and the retainer can cause the sealing ring to be possibly deviated when being subjected to a large axial force, thereby affecting the normal sealing of the bearing.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a roller bearing, its seal structure sets up with the holder is integrative to the components of a whole that can function independently assembly of sealing washer with the holder has been avoided, thereby makes this roller bearing assembling process simple quick more, and this arc seals the sealed stability of flange stronger.
In order to realize the purpose, the utility model discloses a technical scheme is: the utility model provides a roller bearing, includes inner circle and outer lane, be provided with the raceway between inner circle and the outer lane, the rolling is provided with the roller in the raceway, be provided with the holder on the roller, be provided with sealed dog on the holder, set up conflict sealing strip and limit seal strip on the sealed dog, conflict sealing strip and outer lane inner peripheral surface inconsistent setting, limit seal strip and inner circle outer peripheral face inconsistent setting, limit seal strip forms the sealed flange of arc that is used for sealed roller bearing with the combination of conflict sealing strip.
The beneficial effect who so sets up: adopt above-mentioned scheme, it is inconsistent with outer lane inner peripheral surface and inner circle outer peripheral surface respectively to set up conflict sealing strip and spacing sealing strip on the holder, and this conflict sealing strip has formed the sealed flange of arc with the combination of spacing sealing strip, thereby realize the inside sealing of this roller bearing, because this roller bearing's seal structure sets up with the holder is integrative, so compare in current components of a whole that can function independently setting, roller bearing's assembling process is comparatively simple quick, only need during the dismantlement with the holder pull down alright just maintain the bearing inside, it is more laborsaving convenient to dismantle, and can offset this axial force through the holder when the sealed flange of arc receives the axial impact force, and the flange that the arc set up can more effectively cushion the axial force, so this roller bearing's seal structure is compared in the sealed stability of the seal structure of current sealing washer stronger.
As the utility model discloses a further setting, the inner circle outer peripheral face is provided with the spacing groove along the axial, spacing sealing strip forms the axial of holder spacing with the spacing groove cooperation of pegging graft.
The beneficial effect who so sets up: by adopting the scheme, the limiting groove is arranged in the axial direction of the outer peripheral surface of the inner ring, and the limiting sealing strip is in plug-in fit with the limiting groove so as to further offset the axial force received by the arc-shaped sealing flange, thereby ensuring the sealing stability of the arc-shaped sealing flange.
As the utility model discloses a further setting, sealed dog upper surface indent is formed with the first oil storage tank that is used for storing the outer lane fluid that splashes with the conflict sealing strip, sealed dog lower surface indent is formed with the second oil storage tank that is used for storing the inner lane fluid that splashes with the combination of spacing sealing strip.
The beneficial effect who so sets up: by adopting the scheme, the first oil storage tank is arranged for collecting and storing the lubricating oil splashed when the outer ring operates, and the second oil storage tank is arranged for collecting and storing the lubricating oil splashed when the inner ring operates, so that the waste caused by the splashing of the oil liquid when the bearing operates is avoided.
The present invention will be further described with reference to the accompanying drawings.
Drawings
FIG. 1 is a schematic view of the overall structure of the embodiment of the present invention;
fig. 2 is an enlarged view of a portion a of fig. 1 according to an embodiment of the present invention.
Detailed Description
The utility model discloses a concrete embodiment is shown in fig. 1-2, a roller bearing, including inner circle 1 and outer lane 2, be provided with the raceway between inner circle 1 and the outer lane 2, the roll is provided with roller 3 in the raceway, be provided with holder 4 on the roller 3, be provided with sealed dog 41 on the holder 4, set up conflict sealing strip 42 and limit sealing strip 43 on the sealed dog 41, conflict sealing strip 42 and 2 inner peripheral surfaces inconsistent settings in outer lane, limit sealing strip 43 and the 1 outer peripheral face inconsistent setting of inner circle, limit sealing strip 43 forms the arc sealing flange 5 that is used for sealed roller 3 bearing with conflict sealing strip 42 combination. The beneficial effect who so sets up: by adopting the scheme, the supporting sealing strip 42 and the limiting sealing strip 43 arranged on the retainer 4 are respectively supported against the inner circumferential surface of the outer ring 2 and the outer circumferential surface of the inner ring 1, and the interference seal strip 42 and the limit seal strip 43 form an arc-shaped sealing rib 5 in combination, thereby achieving sealing inside the roller 3 bearing, because the sealing structure of the roller 3 bearing is provided integrally with the cage 4, compared with the existing split arrangement, the roller 3 bearing has the advantages that the assembly process is simpler and quicker, the interior of the bearing can be maintained only by detaching the retainer 4 during detachment, the detachment is more labor-saving and convenient, when the arc-shaped sealing flanges 5 are subjected to axial impact force, the axial force can be counteracted through the retainer 4, and the arc-shaped flanges can more effectively buffer the axial force, therefore, compared with the sealing structure of the existing sealing ring, the sealing structure of the roller bearing has stronger sealing stability.
The outer peripheral surface of the inner ring 1 is provided with a limit groove 11 along the axial direction, and the limit sealing strip 43 is in insertion fit with the limit groove 11 to form the axial limit of the retainer 4. The beneficial effect who so sets up: by adopting the above scheme, the axial of the outer peripheral surface of the inner ring 1 is provided with the limiting groove 11, and the limiting sealing strip 43 is in insertion fit with the limiting groove 11 so as to further counteract the axial force received by the arc-shaped sealing flange 5, thereby ensuring the sealing stability of the arc-shaped sealing flange 5.
The upper surface of the sealing stopper 41 is concave, and a first oil storage groove 44 for storing oil splashed by the outer ring 2 is formed by the sealing stopper 41 and the abutting sealing strip 42, and the lower surface of the sealing stopper 41 is concave and is combined with the limiting sealing strip 43 to form a second oil storage groove 45 for storing oil splashed by the inner ring 1. The beneficial effect who so sets up: by adopting the scheme, the first oil storage tank 44 is arranged for collecting and storing the lubricating oil splashed when the outer ring 2 operates, and the second oil storage tank 45 is arranged for collecting and storing the lubricating oil splashed when the inner ring 1 operates, so that the waste caused by the splashing of the oil liquid when the bearing operates is avoided.
The utility model discloses do not confine the above-mentioned embodiment to, the general technical personnel in this field can adopt other multiple embodiments to implement according to the utility model discloses a, perhaps all adopt the utility model discloses a design structure and thinking do simple change or change, all fall into the utility model discloses a protection scope.
