Abstract
The utility model relates to a kind of roller bearing carrying sealing, comprise the two rib outer ring of bearing and without rib inner ring, some cylinder rolling elements are provided with in the space that inner ring and outer ring surround, the internal diameter of inner ring and both sides, outer ring is slotted respectively accordingly, in the inner ring of the same side and the groove of outer ring, inlays seal ring.In order to strengthen sealing effect, described seal ring adopts lips or many bead structures, and seal ring adopts the oil resistant rubber structure of band skeleton.The utility model bearing self is with seal ring, and instead of primitive axis and hold sealing on casing equipment, inner ring cancels slope, raceway groove place, general employing grease lubrication, this design is better than the sealing effect of bearing support, and good sealing ensure that bearing lubrication effect, thus ensure that the normal service life of bearing.Decrease the complexity of axle bearing mount portion position part simultaneously, be convenient to installation and maintenance, alleviate labor intensity, improve working efficiency.
Description
Technical field
The utility model relates to bearing, particularly a kind of roller bearing of NU structure.
Background technique
NU roller bearing of the prior art, the main labyrinth of equipment bearing shell that relies on completes sealing, the seal structure complex on equipment, sealing effect difference and not easily installing.
Summary of the invention
The technical problems to be solved in the utility model is to provide one and improves sealing effect, the roller bearing carrying sealing of the process that the equipment that simultaneously simplifies is installed and keeped in repair.
For solving above technical problem, the utility model improves on the basis of the roller bearing of existing NU structure.
A kind of roller bearing carrying sealing of the utility model, comprise the two rib outer ring of bearing and without rib inner ring, some cylinder rolling elements are provided with in the space that inner ring and outer ring surround, the internal diameter of inner ring and both sides, outer ring is slotted respectively accordingly, in the inner ring of the same side and the groove of outer ring, inlays seal ring.
In order to strengthen sealing effect, described seal ring adopts lips or many bead structures, and further, seal ring adopts the oil resistant rubber structure of band skeleton.
The utility model, for the improvement of a kind of roller bearing (NU structure), improves for roller bearing sealing position specifically.The utility model bearing self is with seal ring, and instead of primitive axis and hold sealing on casing equipment, inner ring cancels slope, raceway groove place, general employing grease lubrication, this design is better than the sealing effect of bearing support, and good sealing ensure that bearing lubrication effect, thus ensure that the normal service life of bearing.Decrease the complexity of axle bearing mount portion position part simultaneously, be convenient to installation and maintenance, alleviate labor intensity, improve working efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1-outer ring, 2-inner ring, 3-cylinder rolling element, 4-seal ring, 5-retainer.
Embodiment
In order to make those skilled in the art better understand the utility model, below in conjunction with accompanying drawing, explanation clear, complete is further done to the utility model.
The roller bearing carrying sealing shown in Fig. 1, comprise the two rib outer ring 1 of bearing and without rib inner ring 2, some cylinder rolling elements 3 are provided with in the space that inner ring 2 and outer ring 1 surround, cylinder rolling element is separated equably by retainer 5, the internal diameter of inner ring 2 and both sides, outer ring 1 is slotted respectively accordingly, inlay seal ring 4 in the inner ring 2 of the same side and the groove of outer ring 1, so just make bearing both sides all with seal ring 4.
Seal ring 4 adopts lips or many bead structures.Seal ring 4 shown in Fig. 1 adopts the oil resistant rubber structure of band skeleton, and this structure fixes oil resistant rubber at the inner side surface of Steel Skeleton, has good sealing effect.
The claimed scope of the utility model is not limited to above embodiment; to those skilled in the art; the utility model can have various deformation and change, all in design of the present utility model and any amendment, the improvement done within principle be equal to replacement and all should be included within protection domain of the present utility model.
