Summary of the invention
For overcoming the shortcoming existed in prior art, the rotary main shaft that goal of the invention of the present utility model is to provide a kind of single point mooring system holds, described main bearing compact in design, saving space, saving material.
For realizing goal of the invention of the present utility model, the utility model provides the rotary main shaft in a kind of floating drum member 1 of Single-point system to hold, it comprises interior ring, outer shroud and a plurality of roller or tapper, wherein, interior ring has two annular plane of inclination at excircle, and a plurality of rollers or tapper are arranged on two annular plane of inclination and are embedded in outer shroud.
Preferably, outer shroud is comprised of symmetrical outer shroud top and outer shroud bottom.
Preferably, two annular plane of inclination symmetries.
Preferably, the angle in the tangent plane of the excircle of two annular plane of inclination and interior ring all at 1 degree between 89 degree.
Preferably, be placed with lower sealing ring 17 between interior ring 11 and outer shroud bottom 13.
Preferably, be placed with upper sealing ring 16 between interior ring 11 and outer shroud top 12.
Preferably, be placed with side sealing ring 18 between outer shroud top 12 and outer shroud bottom 12.
Preferably, evenly be provided with a plurality of through holes 20 on outer shroud.
Compared with prior art, rotary main shaft that the utility model provides holds two row's rollers or tapper 14,15 are in tilted layout in two annular plane of inclination of interior ring 11, utilize roller or tapper to bear the load of substantially horizontal, and without the roller of extra vertical placement, can make like this rotary main shaft hold layout compacter, save space, save material.
The accompanying drawing explanation
Fig. 1 is the composition schematic diagram of single point mooring system;
Fig. 2 is the schematic perspective view that rotary main shaft that the utility model provides holds;
Fig. 3 is the rotary main shaft loading end schematic diagram that the utility model provides.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing, identical reference character means identical parts.
Fig. 2 is the schematic perspective view that rotary main shaft that the utility model provides holds.Fig. 3 is the rotary main shaft loading end schematic diagram that the utility model provides.As Figure 2-3, rotary main shaft in the floating drum member 1 of the Single-point system that the utility model provides is contracted and is drawn together interior ring 11, outer shroud and a plurality of roller or tapper 14 and 15, wherein, the cross section that interior ring 11 has radially at excircle is the first trapezoidal bulge loop 19, and bulge loop has two symmetrical annular plane of inclination; Outer shroud has outer shroud top 12 and outer shroud bottom 13, and the cross section that outer shroud has radially at inner circumference is the second trapezoidal annular groove; The second trapezoidal height trapezoidal with first is identical, and the second trapezoidal upper base is greater than the first trapezoidal upper base, and the second trapezoidal going to the bottom is greater than the first trapezoidal going to the bottom; The bulge loop of interior ring is placed in inner annular recess and a plurality of rollers or tapper 14 and 15 evenly are arranged on two annular plane of inclination of interior ring 11, so, the bulge loop that is provided with roller or tapper 14 and 15 can be embedded in outer shroud annular groove in.Evenly be provided with a plurality of through holes 20 on outer shroud.Two trapezoidal waists and the angle between base at 1 degree between 89 degree, the angle in tangent plane of excircle that so makes two annular plane of inclination and interior ring at 1 degree between 89 degree.
Lower row's roller or tapper 15, between interior ring 11 and outer shroud bottom 13, encircle 11 downward and outside motion in restriction.11 motion upward and outward, between interior ring 11 and outer shroud top 12, is encircled in upper row's roller or tapper position 14 in restriction.After outer shroud top 12 and 13 couplings of outer shroud bottom, just do not have relative translation between interior ring 11, outer shroud top 12 and outer shroud bottom 13, but interior ring 11 still can freely rotate relative to outer shroud top 12 and outer shroud bottom 13.Upper sealing ring 16, lower sealing ring 17 and side sealing ring 18 surround the space of a sealing, and in protection, row's roller or tapper 14 and lower row's roller or tapper 15 are not subject to the intrusion of externalities and foreign matter, protect inner oiling agent can not lose efficacy or run off yet.When rotary main shaft holds in level and state of rest, the load that interior ring 11 bears will pass to outer shroud bottom 13 by lower row's roller or tapper 15.When rotary main shaft holds in inclination or motion state, the load that interior ring 11 bears will be by outer shroud top 12 and outer shroud bottom 13 shareds.
The integration that rotary main shaft holds is installed can divide four steps: (one) is inverted in level table by outer shroud top 12, the row's of inserting roller or tapper 14; (2) upper sealing ring 16, lower sealing ring 17 are enclosed within on interior ring 11, hang in outer shroud top 12, with interim clamp fixedly outer shroud top 12 and interior ring 11; (3) outer shroud bottom 13 is flat on to level table, inserts lower row's roller or tapper 15 and side sealing ring 18; (4) the outer shroud top 12 and the interior ring 11 that fix are sling, upset, hang in outer shroud bottom 13, with bolt, fixes, and removes interim clamp.
The utility model has been optimized the topology layout that rotary main shaft holds, by two row's rollers or tapper 14,15 are in tilted layout in the annular plane of inclination up and down of interior ring 11, utilize roller or tapper to bear the load of substantially horizontal, and without the roller of extra vertical placement, can make like this rotary main shaft hold layout compacter, save space, save material.Outer shroud top 12 and outer shroud bottom 13 are the mirror image symmetry, are convenient to machining and installation.Upper sealing ring 16, lower sealing ring 17 and side sealing ring 18 adopt identical design, have strengthened the reliability of seal ring.
More than being described with reference to the accompanying drawings the utility model, is only for explaining claims but those of ordinary skills it should be known that specification.But protection domain of the present utility model is not limited to specification.In the technical scope that any those skilled in the art of being familiar with disclose at the utility model, the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
