Abstract
The utility model relates to a durable mill special bearing comprising an outer ring and an inner ring, wherein two lines of roller paths are parallelly arranged between the outer ring and the inner ring of the bearing; a plurality of rollers are parallelly arranged in the roller paths; a group of retainers are arranged between each pair of rollers which are arranged in parallel; the outer end surfaces of each pair of rollers are provided with a sealing device which comprises a dustproof cover, an elastic damping ring and a seal ring with a framework; each group of retainers are provided with oil through holes to lead the lubricating oil to be smooth, thus ensuring the retainers to accurately guide the rollers; and the seal ring with the framework in the sealing device is a lip-shaped seal ring to lead the rolling oil outside the bearing to be hardly immersed into the bearing. The utility model is the bearing with the retainer, can accurately guide the rollers, has good sealing effect, and prolongs the service life of the bearing.
Description
(1) technical field: the utility model relates to machinery and uses bearing, a kind of durable type milling train special bearing of using as backing roll especially for metallurgical rolling machinery.
(2) background technology: in existing like product, the rolling mill bearing that is used as backing roll adopts the simple full-complement cylinder roller structure of geometry (referring to Fig. 1) mostly, and wall thickness relative plain bearing in outer ring is abundant especially, can bear very big radial load.The lubricated of bearing enters the inner ring oilhole by the oil filler point on the axle, and be lubricated to both sides roller fuel feeding by the inner ring oilhole.Because of there are two ribs the outer ring that has cylinder roller bearing now, roller is by two lip-guideds, because the roll-force that bear the outer ring is big especially, leans on two ribs of end face to be easy to break.Influence the service life of bearing.Sealing device is equipped with in outer face at the roller that has bearing now, and it is used for stoping the rolling of outside to go into bearing inside with oil immersion by simple seal cover and seal washer.But because seal is poorly sealed sometimes, allow the rolling of bearing outside go into bearing inside easily, (, can not mix use owing to rolling lubrication oil selection with oil and bearing is different with oil immersion.) can shorten the service life of bearing like this.
(3) summary of the invention: the purpose of this utility model has provided the guide rolls of energy normal solution, and sealing effectiveness is good, prolongs a kind of durable type milling train special bearing of bearing life.
The concrete scheme of the utility model is: a kind of durable type milling train special bearing, comprise outer ring, inner ring, between bearing outer ring and inner ring, be set side by side with two row raceways, several row of rollers are listed in the raceway, it is characterized in that: between every pair of roller side by side, be provided with one group of retainer, outer face at every pair of roller is provided with sealing device, and this device includes the sealing ring of dust cap, circlip and band skeleton.
A kind of durable type milling train special bearing is characterized in that: be provided with oil through in described every group of retainer.Solution lubricating oil is unobstructed, thereby makes retainer energy normal solution ground guide rolls.
A kind of durable type milling train special bearing is characterized in that: the sealing ring of the band skeleton in the described sealing device is lip-type packing.Allow the rolling of bearing outside be difficult for immersing bearing inside with oil.
The utility model is a band retainer bearing, energy normal solution guide rolls, and sealing effectiveness is good, prolongs the durable type milling train special bearing of bearing life.
