Abstract
A sealing four-row cylindrical roller bearing includes dual external rings, dual internal rings, a retaining frame, and four row rollers. The four-row cylindrical roller bearing is assembled by the dual external rings, dual internal rings, retaining frame and a plurality of cylindrical rollers. The utility model has the technical key points of that two end surfaces of the four-row cylindrical roller bearing is provided with dual-lip exposed framework sealing ring. The utility model has the advantages of that as the sealing ring of the utility model is a dual-tip exposed framework sealing structure, the structure is simple, the assembly is convenient, the utility model has extremely effect on the low-pressure lubrication system for a rolling mill roller bearing, especially the profile of the sealing ring makes the tip of the sealing ring and the rotary surface of the sealing have good following performance, the external tip prevents the external water and polluted impurities from entering in, the internal tip prevents the lubricant from externally leaking, the sealing performance is good, and the service life of the bearing is prolonged.
Description
Technical field
The utility model relates to a kind of bearing structure, particularly relates to a kind of sealed four-row roller bearing structure.
Background technique
Existing FCD type four-line column roller bearing is two outer rings, two interior coil structures, outer astragal rib.This bearing, poor sealing performance, i.e. waterproof and dustproof poor performance, and easily cause oil leak, thus reduced the working life of bearing.
Summary of the invention
Purpose of the present invention is at the problems referred to above, and a kind of band sealed four-row roller bearing is provided, this bearing products waterproof and dustproof, and particularly grease proofing leaking performance is good, the bearing long service life.
The technological scheme that adopts is:
The sealed four-row roller bearing comprises two outer rings, two inner ring, retainer and four-row cylindrical roller.Two outer rings, two inner ring, retainer and a plurality of cylindrical roller assembly four-line column roller bearing.Its technological points is that the both ends of the surface at four-line column roller bearing are equiped with the lips mouth and expose skeleton seal ring.
Lips mouth rubber seal on interior ring skirt constitutes above-mentioned seal ring by metal ring that has the interior ring skirt that extends internally and casting.
Above-mentioned seal ring exposes skeleton and bearing outer ring with the 0.02-0.10mm interference fit.And seal lip contacts with surface of revolution (being inner ring) with minimum lip radial force with the radial interference of 0.3-0.4mm.
The contact width of above-mentioned seal ring two lips and inner ring is 8.5mm.
Advantage of the present utility model is:
Because seal ring of the present utility model is that a kind of lips mouth exposes skeleton sealing configuration, simple in structure, easy to assembly, very effective for the rolling-mill roller bearing with low pressure lubricating system, particularly the section configuration of seal ring makes the lip of seal ring and the surface of revolution of sealing have good tracing ability, and outer lip prevents outside moisture content and pollute the impurity invasion that epipharynx prevents the lubricant oil external leakage, good seal performance has improved bearing working life.

Fig. 1 is an a kind of embodiment's of the present utility model structural representation.
Fig. 2 is the ring structure schematic representation.
Embodiment
The sealed four-row roller bearing comprises two outer rings 1, two inner ring 2, retainer 3, four-row cylindrical roller 4 and two seal rings 5.Every line column roller is made up of 35 cylindrical rollers, is assemblied on the retainer respectively.Two outer rings 1, two inner ring 2, retainer 3, four-row cylindrical roller 4 are assembled into four-line column roller bearing.
Two seal rings 5 are installed in the two ends of above-mentioned four-line column roller bearing respectively.Annular metal exposes skeleton 6 and two outer rings 1 with the 0.02-0.10mm interference fit.The outer lip 9 of rubber seal 7 and epipharynx 10 and the radial interference fit of inner ring with 0.3-0.4mm, seal ring two lip contact widths are 8.5mm.
Claims (2)
1, sealed four-row roller bearing, be assembled into four-line column roller bearing by two outer rings (1), two inner ring (2), retainer (3) and four-row cylindrical roller (4), it is characterized in that being equiped with seal ring (5) respectively at the two ends of described four-line column roller bearing; Annular metal exposes skeleton (6) to seal ring (5) and rubber seal (7) constitutes by having, annular metal exposes skeleton (6) interior ring skirt (8), rubber seal (7) has outer lip (9) and epipharynx (10), and rubber seal (7) is fixedlyed connected with interior ring skirt (8); Annular metal exposes skeleton (6) and corresponding bearing outer ring with the 0.02-0.10mm interference fit, the outer lip (9) of rubber seal (7) and epipharynx (10) and corresponding inner ring (2) radial interference fit with 0.3-0.4mm.
2, sealed four-row roller bearing according to claim 1 is characterized in that the rubber seal (7) and the sealing contact width of inner ring (2) are 8.5mm.
