Abstract
The invention provides a nylon roller bearing. A roller is put into a pocket of a holder seat and is connected through a holder cover to form an inseparable nylon holder assembly, and the nylon holder assembly is sleeved with an outer ring and an inner ring to form a bearing set. The rolling surface of the roller is a completely-convex spherical surface, and roller paths corresponding to the roller are arranged on the outer ring and the inner ring, and blocking edges with tip degrees are arranged on the two sides of the roller path of the outer ring. The nylon roller bearing is sufficient in lubrication, good in heat dissipation and high in precision, the heavy load bearing capability is improved, and the use requirements in special working conditions can be met.
Description
Technical field
The present invention relates to a kind of nylon roller bearing, it is applied to ocean large ship tractor tug and oil platform tender, joins
It is placed on ship's propeller and 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 nylon roller bearing.Technical solution of the present invention is as follows:
A kind of nylon 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
Having the rib of tip 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 nylon to make.
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, nylon material
The retainer of matter has more that vibration is little, and noise is low, and caloric value is low, and bearing capacity is high, and the use that can reach special operation condition is wanted
Ask.

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 ＇, the nylon 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 nylon material to make, by keeping stand (4) and retainer
The retainer that lid (5) is constituted is pocket cellular type retainer, and roller 3 is connected by retainer lid 5 in being placed on holding stand 4 pocket hole
Connect the inseparable retainer assembly of formation, then be 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, nylon material
The retainer of matter has more that vibration is little, and noise is low, and caloric value is low, and bearing capacity is high, and the use that can reach special operation condition is wanted
Ask.
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 nylon roller bearing, roller (3) connected by retainer lid (5) in being placed on holding stand (4) pocket hole
Connecing the inseparable retainer assembly of formation, then be one group of bearing with outer ring (1), inner ring (2) trap, roller (3) rolls
Surface is the most convex sphere, and outer ring (1), inner ring (2) are provided with its corresponding raceway, set in outer ring (1) raceway both sides
There is the rib with 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 nylon to make.
Nylon roller bearing the most according to claim 1, it is characterised in that: by keeping stand (4) and retainer lid
(5) retainer constituted is pocket cellular type retainer.
