Description
Technical field
The present invention relates to a kind of bearing, feature relates to a kind of novel four-line column roller bearing.
Background technique
The four-line column roller bearing that existing milling train is commonly used divide FC,, FCD type, FCDP type, as shown below respectively, wherein the FC type is two outer rings, single interior coil structures, and the FCD type is two outer rings, two interior coil structures, and the FCDP type is two outer rings, two inner ring, two outer back-up ring, two outer ring spacer structure.
The reinforced structure of existing FC has following problem technically:
Because outer astragal rib, must there be grinding wheel groove (or being called oil duct) rib and raceway jointing place, oil duct is not sufficiently oily with rib and raceway transition position in Vehicle Processing, be prone to corner angle, formation stress is concentrated, and can stress concentrate effect and make the oil duct position quenching microscopic crack occur easily in heat treatment process like this, thereby cause that the bearing parts early fatigue destroys, even fracture, the reliability and the working life of reducing bearing.
Because outer ring and roller, retainer form an inseparable outer assembly, in the bearing using process, if the outer ring is damaged, roller or retainer are that inseparable assembly is scrapped with the outer ring because of them with the outer ring also even without damage; In like manner, if roller or retainer damage, be that inseparable assembly is scrapped the outer ring with the outer ring also because of them.Above-mentionedly either way caused the wasting of resources.
Two row roller lengths of same outer assembly equate that in the bearing rotary course, stress causes fatigue flake easily because of being subjected to continuously on the roller surface of two row roller end face adjacents, scars such as fin occur, makes bearing early failue.
The retainer of the reinforced structure of FC belongs to the encapsulation retainer, lubricating grease storage deficiency for open retainer, and lubricating condition is relatively poor.
Summary of the invention
The purpose of this utility model is the above-mentioned deficiency at the reinforced structure of FC, and the interchangeable high load of a kind of each assembly, long-life novel four-line column roller bearing are provided.
The technological scheme of taking for the realization the purpose of this utility model is as follows:
A kind of novel four-line column roller bearing, comprise an inner ring, two outer rings, between adjacent two outer rings outer ring spacer is arranged, two outer rings, one outer back-up ring respectively is installed on the non-adjacent end face, one integral cage is installed between inner ring and the outer ring, integral cage is by keeping stand and retainer lid to be connected into one by keeping the square toes rivet hot pressing on the stand, keep forming several pocket holes naturally in the middle of stand and the retainer lid, in each pocket hole length is installed all, short two line column rollers, whole retainer and roller are formed an inseparable assembly, it is characterized in that the outer ring of this bearing, inner ring, roller cage assembly and outer ring spacer, be flexible connection between the outer back-up ring.
The roller length in the adjacent in a circumferential direction pocket of above-mentioned retainer hole is staggered.
Be along the circumferential direction to have several arc gaps in intermediate portion, above-mentioned retainer pocket hole.
Characteristics of the present utility model are that the outer ring is not with rib, have replaced the effect of rib with movable outer back-up ring and outer ring spacer.Owing to cancelled rib, work in-process no longer needs grinding wheel groove (being oil duct), fundamentally eliminated because of oil duct position Vehicle Processing stress and concentrated the phenomenon that causes the heat-treatment quenching crackle, greatly improved the reliability of bearing, prolonged the working life of bearing.Outer ring, inner ring and roller cage assembly all are designed to separable mutually, and require inside and outside circle all interchangeable, so in the bearing using process, when the outer ring is damaged, only need to change the outer ring, when inner ring damages, only need to change inner ring, when the roller cage assembly damages, only need to change the roller cage assembly, in like manner, when outer ring back-up ring or outer ring spacer damage, only need to change outer back-up ring or outer ring spacer.Like this, advantageously prolong the life cycle of bearing, reduced the consumption of bearing, promoted the increase of bearing user economic benefit.Two row roller length differences of same outer assembly, and the roller length in adjacent in a circumferential direction pocket hole is staggered, in the bearing rotary course, can avoid effectively that stress causes fatigue flake because of being subjected to continuously on the roller surface of two row roller end face adjacents, the generation of scar phenomenons such as fin occur, make roller surface stressed evenly.Adopt computer optimization to be designed to reinforced structure, make bearing have very high bearing capacity, retainer is used square toes rivet weld entity brass retainer simultaneously, improved the reliability of roller cage assembly, in addition, along the circumferential direction mill out several arc gaps in intermediate portion, retainer pocket hole, increased the lubricating grease loading, improved lubricating condition.The utility model project organization is reasonable, cost is low, helps applying.
