Abstract
The invention belongs to the technical field of self-aligning roller bearing manufacturing, and particularly relates to a self-aligning roller bearing for elevator sealing. The self-aligning roller bearing comprises an outer ring, an inner ring, a retainer, a rolling body and a double-lip sealing piece. The retainer is located between the outer ring and the inner ring. The rolling body is located in a pocket hole of the retainer. The outer diameter part of the double-lip sealing piece is inlaid in a sealing groove in the inner diameter part of the outer ring in an interference manner. Double lips of the double-lip sealing piece make contact with the inner ring. A ring groove is formed between the double-lip sealing piece and the inner ring. Double-lip sealing is adopted in the self-aligning roller bearing, and the self-aligning roller bearing is used on an elevator tractor. A front contact lip edge and a rear contact lip edge are arranged on a double-lip sealing structure of the self-aligning roller bearing, compared with one-lip sealing, the ring groove is additionally arranged, a pressure buffering chamber and a lubricating grease storage chamber are formed by the ring groove and the inner ring, the passing sealing winding path is lengthened no matter for leakage of lubricating grease or entering of outer dust, and the sealing performance is improved.
Description
Technical field
The invention belongs to self-aligning roller bearing manufacturing technology field is and in particular to aligning roller axle is used in a kind of sealing of elevator
Hold.
Background technology
With building floor height more and more higher, elevator has become the common demands of skyscraper, but, existing traction elevator
Drag device in, sealing self-aligning roller bearing is all generally single lip seal, and sealing is poor, the spilling and external dust of grease
Entrance all can lead to affect bearing normal operation.
Content of the invention
In order to overcome the shortcomings of above-mentioned prior art presence, it is an object of the invention to provide a kind of elevator sealing regulation of mental activities rolls
Sub- bearing, hence it is evident that improving sealing property, reduces oils and fatss and spills and external dust entrance.
For achieving the above object, the technical scheme is that a kind of elevator sealing self-aligning roller bearing, including outer ring,
Inner ring, retainer, rolling element and two-lip seal；Described retainer is located between outer ring and inner ring, and rolling element is located at retainer
Pocket hole in；The external diameter of described two-lip seal is embedded in the seal groove on the internal diameter of outer ring by way of interference, and lips are close
The lips of sealing are contacted with inner ring；Form annular groove between described two-lip seal and inner ring.
Further, described two-lip seal is contacted with inner ring internal-and external diameter.
Further, the described inner ring internal-and external diameter contacting with two-lip seal adopts curvature surface.
Further, described two-lip seal includes outer lip and epipharynx, outer lip and epipharynx respectively with inner ring interference fit.
Further, the magnitude of interference of described outer lip is less than the magnitude of interference of epipharynx.
Further, at described rolling element and deep inner ring outer diameter contact, groove is set.
Beneficial effects of the present invention：The self-aligning roller bearing of the present invention adopts double-lip seal, for elevator traction machine, with
Single lip seal is compared, and the two-lid sealing structure of the present invention has contact antelabium at before and after two, increased annular groove at, this annular groove with interior
Circle forms the storage room of pressure buffer chamber and grease, either the entrance spilling still external dust of grease, process
Sealing labyrinth is all lengthened, and improves sealing property.
Brief description
Fig. 1 is the structural representation of the present invention；
In figure：1st, outer ring, 2, inner ring, 3, retainer, 4, rolling element, 5, two-lip seal, 6, groove, 7, outer lip, 8, epipharynx, 9, ring
Groove.
Specific embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Elevator sealing self-aligning roller bearing as shown in Figure 1, including outer ring 1, inner ring 2, retainer 3, rolling element 4 and double
Lip seal 5；Retainer 3 is located between outer ring 1 and inner ring 2, and rolling element 4 is located in the pocket hole of retainer 3；Two-lip seal 5
External diameter inlayed by way of interference in the seal groove on outer internal diameter, the lips of two-lip seal are contacted with inner ring 2；Described
Form annular groove 9 between two-lip seal 5 and inner ring 2.
Two-lip seal 5 is contacted with inner ring 2 internal-and external diameter, and inner ring 2 internal-and external diameter contacting with two-lip seal 5 adopts curvature
Face.Two-lip seal 5 includes outer lip 7 and epipharynx 8, outer lip 7 and epipharynx 8 respectively with inner ring 2 interference fit.The magnitude of interference of outer lip 7
The magnitude of interference less than epipharynx 8.At rolling element 4 and deep inner ring 2 outer diameter contact, groove 6 is set.
Lips are respectively adopted the different magnitudes of interference, and the magnitude of interference of outer lip 7 is less than the magnitude of interference of epipharynx 8, and now, bearing exists
Temperature rise in life span is the slowest, and leakage fat is minimum, and sealing property significantly improves.Additionally, two-lip seal 5 is in the mistake of bearing operation
Pass through in journey to constitute annular groove 9 with inner ring 2 rib between lips, this annular groove 9 and inner ring 2 form the storage of pressure buffer chamber and grease
Deposit room, either the entrance spilling still external dust of grease, the sealing labyrinth of process is all lengthened, and improves sealing
Performance.
