Abstract
The utility model provides one to have aligning roller bearing, be placed on by roller and keep being connected to form inseparable retainer assembly by retainer lid in stand pocket hole, be one group of bearing with outer ring, inner ring trap again, roller rolls surface is entirely convex sphere, outer ring, inner ring are provided with its corresponding raceway, are provided with the rib with tip degree in outer ring raceway both sides.The beneficial effects of the utility model: lubrication is abundant, good heat dissipation, and precision is high, improve compound heavy duty ability, can reach the usage requirement of special operation condition.
Description
Technical field
The utility model relates to one and has aligning roller bearing.Application ocean large ship tractor tug and oil platform tender, be matched in ship's propeller and support blade work bearing.
Background technique
Propulsion device blade pendulum angle is about ± and 60 °, this just requires that bearing bears sizable radial load and corresponding moment of torsion, and the edge stress that produces of bearing race thus, the discharging quantity needing bearing self to have is eliminated.
Existing roller bearing structure can not meet some privileged site operating mode at all and use, and especially have aligning requirement to bearing, this just must have a kind of bearing of new structure to meet the need of market.
Summary of the invention
In order to the large radial load of the roller bearing realizing vertical installation and corresponding moment of torsion special operation condition conditional request, bearing inner race needs radial deflection ± X ＇, and the utility model provides one and has aligning roller bearing.
Technical solution of the present utility model is: one has aligning roller bearing, be placed on by roller and keep being connected to form inseparable retainer assembly by retainer lid in stand pocket hole, be one group of bearing with outer ring, inner ring trap again, it is characterized in that: roller rolls surface is entirely convex sphere, outer ring, inner ring are provided with its corresponding raceway, are provided with the rib with tip degree in outer ring raceway both sides.
The tip degree θ of described outer ring (1) raceway both sides rib is 17 ＇ ± 1 ＇ 30 ".
The utility model compared with the existing technology have lubrication fully, good heat dissipation, precision is high, improves compound heavy duty ability, can reach the usage requirement of special operation condition.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial structurtes enlarged view of Fig. 1.
Fig. 3 is roller schematic diagram of the present utility model.
In figure: 1, outer ring, 2. inner ring, 3. roller, 4. keep stand, 5. retainer lid.
Embodiment
In order to the large radial load of the roller bearing meeting vertical installation and corresponding moment of torsion special operation condition conditional request, its bearing inner race 2 needs radial deflection ± X ＇, one of the present invention has aligning roller bearing, convex form is helped in the design of its cylindrical roller 3, radial deflection ± X ＇ is met with FEM (finite element) model checking convexity radius and convexity amount, bearing outer ring 1 raceway both sides are with the two rib of tip degree, its tip degree θ is 17 ＇ ± 1 ＇ 30 ", effectively can eliminate complete convex roller end face and contact with rib and produce stress concentration phenomenon.The present invention is placed on by roller 3 and keeps being connected to form inseparable retainer assembly by retainer lid 5 in stand 4 pocket hole, then is one group of bearing with outer ring 1, the 2-in-1 cover of inner ring.
The utility model is applied to the support blade work bearing of ship's propeller.Through overtesting, product reliability is high, stability is strong, meets designing requirement.
Claims (2)
1. one kind has aligning roller bearing, be placed on by roller (3) and keep being connected to form inseparable retainer assembly by retainer lid (5) in stand (4) pocket hole, be one group of bearing with outer ring (1), inner ring (2) trap again, it is characterized in that: roller (3) rolling surface is entirely convex sphere, outer ring (1), inner ring (2) are provided with its corresponding raceway, are provided with the rib with tip degree in outer ring (1) raceway both sides.
2. one according to claim 1 has aligning roller bearing, it is characterized in that: the tip degree θ of described outer ring (1) raceway both sides rib is 17 ＇ ± 1 ＇ 30 ".
