Description
Technical field
The utility model relates to field of bearings, concretely, relates to a kind of Biserial cylindrical roller bearing that is used to bear the staggered roller integral type retainer of new structure length with impulsive load heavy-duty applications occasion.
Background technique
Structures such as that roller bearing is divided into usually is single-row, biserial and four row; Because it can bear heavy load and impact load; Be widely used in large and medium motor, rolling stock, machine tool chief axis, internal-combustion engine, generator, combustion gas turbine, speed reducer, rolling mill, vibrating sieve and handling machinery etc., wherein the relative single row roller bearing of Biserial cylindrical roller bearing can bear higher radial load.Be improvement bearing internal structure or retainer structure with the design distillation of bearing at present to disintegrator.The first adopts the length roller to be uniformly distributed with, and retainer adopts split-type structural and from riveting, the shortcoming of this kind design is the retainer insufficient strength, causes the bearing fracture failure in the using process in early days; It two is that retainer adopts fabricated structure, and promptly two ends are retainer lids, and the middle part is to keep stand; Keep a stand two ends protrusion part; In order to cooperate with the retainer lid, be evenly equipped with some through holes at retainer lid and the corresponding position of seat circumferencial direction, connect by resilient key.This kind design advantage is that retainer intensity is strengthened to some extent, but its shortcoming is a cost to sacrifice bearing load carrying capacity, directly influences the working life of bearing.And the process-cycle of composite cage is longer, and cost of production is higher, and technology is not mature enough.
Summary of the invention
In view of the defective that prior art exists, the purpose of the utility model provides a kind of saving manufacture cost, shortens the manufacture cycle, reduces assembling difficulty, prolongs the bearing staggered roller one retainer Biserial cylindrical roller bearing of length in working life.The utility model is according to heavy load and the special operation condition of impact load is arranged, and the retainer structure and the bearing internal structure of bearing are innovated improvement.
The utility model is made up of outer ring, inner ring, outer back-up ring, long roller, short roller, retainer, and bearing is provided with an outer ring, an inner ring; The staggered length roller that is evenly equipped with 22 of every row of length on the raceway of the centre of outer ring and inner ring, totally 2 row are 44, and outer back-up ring leans against the side that outer ring raceway does not have the slope; Play the effect of sliding damper limit; Outer ring washer encases long roller and short roller with the outer ring, and inner ring does not have rib and has the slope at the raceway two ends, is uniformly distributed with two lubrication oil holes at the internal diameter middle part; Internal diameter one side is provided with straight big chamfering, and opposite side is rounded down; Long roller is processed into short roller surface has 0.024 ± 0.003mm convexity, effectively avoids in the application sets at rolling surface two ends, prolongs bearing working life.Roller is contained in the pocket hole of retainer, and is distributed in the raceway of inner ring.The cutter seal pins roller on the lintel of retainer, makes roller guarantee the flexible fluent phenomenon of rotation and can not drop out retainer at operation process.Long roller, short roller and retainer composition roll frame component.Bearing outer ring does not have rib and has the slope in a side, and two lubrication oil holes that are uniformly distributed with are arranged at the middle part of external diameter simultaneously; Retainer adopts integral structure, and bilateral symmetry is distributed with guide surface apart from the middle part, and retainer end face bilateral symmetry is uniformly distributed with two liftings and uses tapped hole.Rolling element is that circular arc modified line bus is repaiied type, and bearing ring adopts lower bainite to quench, and bearing holder material is aluminum bronze (ZCuAl10Fe3Mn2).
The utility model is compared with existing technology has following beneficial effect:
1. the retainer of the utility model bearing adopts integral structure; Rolling element length is staggered to be uniformly distributed with; The retainer material is an aluminum bronze, and the intensity of retainer has obtained reinforcement, and the total length of roller is able to suitable growth; Design is very beneficial for increasing the bearing capacity of bearing like this, has prolonged the working life of bearing.
2. the utility model bearing roller two is listed as totally; Length is staggered to be distributed between the inside and outside raceway; Can utilize raceway better; Divide the fillet part with two rollers that contact the raceway of corresponding not bearing load to use, can pass through to change the method change in proper order of length roller bearing the contact stress biggest place on the raceway simultaneously, thus the fatigue life of having improved raceway.
3. the utility model bearing outer ring adopts sliding damper limit (promptly outer back-up ring) design, and the benefit that designs like this is the installation and removal of being convenient to bearing, and the concentrated phenomenon of rib oil duct stress of having forgone has simultaneously prolonged working life of bearing.
4. the utility model bearing ring adopts lower bainite to quench; Greatly improved the toughness and the fatigue strength of lasso, compared with normal marquench, its interior tissue is even; Lasso surface and inner even hardness; Dimensional stability improves a lot, and thermal pressure has reduced many, and the bearing impact strength is far longer than marquench.Heat treatment deformation is little simultaneously, noise is lower, antiwear property is better, has effectively promoted product performance, has prolonged the working life of bearing.
5. respectively be evenly equipped with two oilholes on the raceway of the utility model bearing outer ring and inner ring, improve the lubrication state of bearing effectively, more adapt to the residing rugged environment of disintegrator bearing.
6. the utility model bearing holder material adopts aluminum bronze, compares with the brass of normal employing, has higher intensity; Better wear resistance and corrosion resistance; And because the retainer material has adopted aluminum bronze, make the total length of roller obtain certain growth, the bearing capacity of bearing further increases.
7. the utility model retainer is guided by outer ring raceway, between outer ring raceway and retainer guide surface, produces the very thin lubricant film of one deck, has effectively improved the lubricated of bearing.
