Abstract
The utility model relates to the technical field of bearings, in particular to an insert bearing unit with a tooth-type sealing cover which can work in harsh environment. The insert bearing unit is provided with an inner ring, an outer ring, a rolling body arranged between the inner ring and the outer ring, a holding rack for supporting the rolling body, and a sealing ring which is used for sealing and is positioned at the periphery of the rolling body. The insert bearing unit is characterized in that the sealing ring comprises a sealing cover and a sealing lip; the sealing lip is fixed on the inner side of the sealing cover; the sealing cover is riveted and connected on the inner surface of the outer ring; a contact seal is adopted between the sealing lip and the outer surface of the inner ring; the riveting connection between the sealing cover and the inner surface of the outer ring adopts a straight edge tooth-shaped riveting; grooves are formed on the inner surface of the outer ring; tooth-shaped bulges used for clamping into the grooves are formed on the outer surface of the sealing cover; and the sealing lip adopts a three-lip structure. The insert bearing unit has the advantages that the sealing performance is higher; the insert bearing unit is suitable for being applied to harsh environment; the sealing performance can not degrade under a large torque; and the service life of the bearing is longer.
Description
Technical field
The utility model relates to technical field of bearings, especially a kind of tooth-like sealing cover roller bearing units of working under rugged environment.
Background technique
At present, the application of market upper bearing (metal) more and more widely, on Device Hosts such as pump machines, oilfield machinery and farm machinery supporting.Under the situation of work under bad environment, technical quality to bearing requires high especially, especially the sealability of bearing, yet during existing bearing work, be subjected under the very big moment situation, the sealing cover of bearing is loosening easily in the outer ring of bearing, bearing when work bearing inner race fastening screw trip bolt place the phenomenon of transshipping cracking appears easily, the decreased performance that makes sealing, bearing damages easily simultaneously, and the life-span is shorter.
The model utility content
The technical problems to be solved in the utility model is: shortcoming and deficiency in order to solve above-mentioned existence, a kind of tooth-like sealing cover roller bearing units is provided, and be mainly used on the farm machinery.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of tooth-like sealing cover roller bearing units, has inner ring, the outer ring, be arranged on the rolling element between inner ring and the outer ring, the retainer of back-up roller kinetoplast and the seal ring that places the rolling element periphery to be used to seal, seal ring comprises sealing cover and sealing lip, sealing lip is fixed on the inboard of sealing cover, the sealing cover riveted is connected on the inner surface, the sealing lip contact seal is on the inner ring outer surface, its bearing inner race is axially having different hardness on the different cross section, make integrally-built good seal performance, by Die for pressing cap sealing cover being pressed downwards is combined on the internal surface of outer ring, can not produce loosening under big moment.
Further, the connection of sealing cover for convenience, and the performance that connects is good, and the riveted that the sealing cover riveted is connected on the inner surface is connected to straight flange profile of tooth riveted, offer groove on the inner surface, be provided for being snapped into the detent projection in the groove on the outer surface of sealing cover.
In order to make whole good seal performance, sealing lip is three procheilon structures.
The beneficial effects of the utility model are, tooth-like sealing cover roller bearing units of the present utility model, and its sealability is higher, is adapted at working under the environment condition of severe, and sealability can not descend when being subjected to big moment, and the operating life of bearing is longer.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation that partly cuts open of the present utility model;
Fig. 2 is a partial structurtes assembling schematic representation of the present utility model.
Among the figure 1, inner ring, 2, the outer ring, 21, groove, 3, rolling element, 4, retainer, 5, sealing cover, 6, sealing lip, 7, lining ring, 8, Die for pressing cap.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As Fig. 1, tooth-like sealing cover 5 roller bearing units of preferred forms shown in Figure 2, has inner ring 1, outer ring 2, be arranged on the rolling element 3 between inner ring 1 and the outer ring 2, the retainer 4 of back-up roller kinetoplast 3 and the seal ring that places rolling element 3 peripheries to be used to seal, seal ring comprises sealing cover 5 and sealing lip 6, sealing lip 6 is fixed on the inboard of sealing cover 5, sealing cover 5 riveteds are connected on 2 internal surfaces of outer ring, sealing lip 6 contact seals are on inner ring 1 outer surface, its bearing inner race 1 is axially having different hardness on the different cross section, make integrally-built good seal performance, by Die for pressing cap 8 sealing cover 5 being pressed downwards is combined on the internal surface of outer ring 2, can not produce loosening under big moment.
The riveted that sealing cover 5 riveteds are connected on 2 internal surfaces of outer ring is connected to straight flange profile of tooth riveted, offer groove 21 on 2 internal surfaces of outer ring, be provided for being snapped into the detent projection in the groove 21 on the outer surface of sealing cover 5, make things convenient for the connection of sealing cover 5, and the performance that connects is good, sealing lip 6 is three procheilon structures, feasible whole good seal performance.
When the utility model is implemented, the bearing that connects inside and outside circle 2 and rolling element 3 is placed on the lining ring 7 on the worktable, then seal ring is positioned over rolling element 3 tops, by Die for pressing cap 8 with seal ring to pressing down, make the sealing cover 5 of seal ring be fastened in the groove 21 on 2 internal surfaces of outer ring, realize sealing, the seal ring of rolling element 3 opposite sides in like manner connects.Because such design of bearing makes the bearing starting torque in the scope of 1.84NM～3.73NM, guarantees the sealing effect of bearing, and moment of torsion is under 47.54NM when work, and sealing cover 5 can not produce loosening in bearing outer ring 2.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
