Abstract
The invention provides a roller bearing. An inseparable cage assembly is formed by placing a roller in a pocket of a cage seat through connection of a cage cover; the inseparable cage assembly, an outer ring and an inner ring form a group of bearings; the rolling surface of the roller is a fully convex spherical surface; roller paths corresponding to the inner ring and the outer ring are disposed on the inner ring and the outer ring; retaining sides with tip degrees are disposed on the two sides of the roller path of the outer ring. The roller bearing is sufficient in lubrication, good in heat dissipation and high in precision, the composite heavy load capacity is improved, and the usage requirement of a special working condition can be achieved.
Description
Technical field
The present invention relates to a kind of roller bearing, it is applied to ocean large ship tractor tug and oil platform tender, is matched in
Ship's propeller supports blade work bearing.
Background technology
Propeller blade pendulum angle is about ± 60 °, and this just requires that bearing bears sizable radial load and corresponding moment of torsion,
And the edge stress that thus raceway produces, the discharging quantity needing bearing self to have eliminates, existing cylindrical roller axle
Bearing structure can not meet some specific part operating mode at all and use, and especially has regulation of mental activities requirement to bearing, and this has been necessary for one
The bearing of new construction meets the market demand.
Summary of the invention
In order to realize the big radial load of the cylinder roller bearing of vertical installation and corresponding moment of torsion special operation condition condition requirement, in bearing
Circle needs radial deflection ± X ＇, the invention provides a kind of roller bearing.Technical solution of the present invention is as follows:
A kind of roller bearing, roller (3) formed not by retainer lid (5) connection in being placed on holding stand (4) pocket hole
Separable retainer assembly, then be one group of bearing with outer ring (1), inner ring (2) trap, roller (3) rolling surface is complete
Convex sphere, outer ring (1), inner ring (2) are provided with its corresponding raceway, are provided with the tip in outer ring (1) raceway both sides
The rib of degree, the tip degree θ of described outer ring (1) raceway both sides rib is 20 ＇ ± 1 ＇ 30 ", described holding stand (4)
Retainer lid (5) uses bronze ZCuAL10Fe3Mn2Material is made.
It is pocket cellular type retainer by the retainer keeping stand (4) and retainer lid (5) to constitute.
The present invention compared with the existing technology have lubrication fully, good heat dissipation, precision is high, improves compound heavy duty ability, retainer
Have more wearability, impact flexibility, there is more preferable intensity, the use requirement of special operation condition can be reached.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the partial structurtes enlarged drawing of Fig. 1；
Fig. 3 is the roller schematic diagram of the present invention.
In figure: 1. outer ring, 2. inner ring, 3. roller, 4. keep stand, 5. retainer lid
Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme is described, it is clear that described is only a present invention part
Embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are institute under not making creative work premise
The every other embodiment obtained, broadly falls into the scope of protection of the invention.
In order to meet the big radial load of the cylinder roller bearing of vertical installation and corresponding moment of torsion special operation condition condition requirement, its bearing
Inner ring 2 needs radial deflection ± X ＇, a kind of roller bearing of the present invention, and convex form is helped in the design of its cylindrical roller 3,
Meeting radial deflection ± X ＇ with FEM (finite element) model checking convexity radius and convexity amount, bearing outer ring 1 raceway both sides are with tip degree
Double ribs, its tip degree θ is 17 ＇ ± 1 ＇ 30 ", can effectively eliminate complete convex roller end face and contact generation stress collection with rib
Middle phenomenon.Stand (4) and retainer lid (5) is kept to use bronze ZCuAL10Fe3Mn2Material is made, by keeping stand
(4) and the retainer that constitutes of retainer lid (5) is pocket cellular type retainer, roller 3 passes through in being placed on holding stand 4 pocket hole
Retainer lid 5 connects the inseparable retainer assembly of formation, then is one group of bearing with outer ring 1, the 2-in-1 set of inner ring.
The present invention compared with the existing technology have lubrication fully, good heat dissipation, precision is high, improves compound heavy duty ability, retainer
Have more wearability, impact flexibility, there is more preferable intensity, the use requirement of special operation condition can be reached.
Above-described detailed description of the invention, has been carried out the purpose of the present invention, technical scheme and beneficial effect the most in detail
Illustrate, be it should be understood that the detailed description of the invention that the foregoing is only the present invention, be not intended to limit the present invention
Protection domain, all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. done, all
Within protection scope of the present invention should being included in.
Claims (2)
1. a roller bearing, roller (3) connect shape by retainer lid (5) in being placed on holding stand (4) pocket hole
Become inseparable retainer assembly, then be one group of bearing with outer ring (1), inner ring (2) trap, roller (3) rolling surface
For the most convex sphere, outer ring (1), inner ring (2) are provided with its corresponding raceway, are provided with band in outer ring (1) raceway both sides
There is the rib of tip degree, it is characterised in that: the tip degree θ of described outer ring (1) raceway both sides rib is 20 ＇ ± 1 ＇ 30 ",
Described holding stand (4) retainer lid (5) uses bronze ZCuAL10Fe3Mn2Material is made.
Roller bearing the most according to claim 1, it is characterised in that: by keeping stand (4) and retainer lid (5)
The retainer constituted is pocket cellular type retainer.
