Description
Technical field
The utility model relates to a kind of novel wind power wheel hub main shaft connection structure, belongs to technical field of wind power generating equipment.
Background technique
Wind generating technology belongs to new energy field, and along with energy crisis occurs, wind-powered electricity generation is more and more subject to the favor of people, and the single-machine capacity of Wind turbines is also constantly soaring.Existing Large-scale Wind Turbines great majority are horizontal axis upwind Wind turbines, and it needs the energy by wind wheel absorbs to be delivered on main shaft by wheel hub in the mode of moment of torsion usually.
Together with existing wheel hub and main shaft are generally bolted, rely on the frictional force transmitting torque of two junction.Prior art wheel hub main shaft is all plane, along with the continuous increase of single-machine capacity, needs the moment of torsion of transmission increasing, thus needs more bolt to connect the pressure increasing junction plane, and then improve the frictional force of junction plane.So, not only add bolt cost, and need the number of bolts safeguarded to increase in the later stage, add O&M time and cost; And by spatial constraints, bolt quantity can not unconfinedly increase.
Summary of the invention
The purpose of this utility model is to provide a kind of novel wind power wheel hub main shaft connection structure, can overcome the deficiencies in the prior art, increases the pressure of junction plane, improves the frictional force of junction plane, ensures the stability connected.
The purpose of this utility model is achieved through the following technical solutions: a kind of novel wind power wheel hub main shaft connection structure, the casting hub that it comprises casting main shaft and is connected with casting main shaft, one end of described casting hub is provided with joint I, one end of casting main shaft is provided with the joint II mated with joint I, wherein, joint I is by plane contact section I and be connected with plane contact section I and the inner conical surface contact-segment extended internally forms, joint II is by plane contact section II and be connected with plane contact section II and outward extending male cone (strobilus masculinus) contact-segment forms, male cone (strobilus masculinus) contact-segment to insert in inner conical surface contact-segment and with inner conical surface contact-segment close contact, plane contact section II is with plane contact section I close contact and be bolted.
Interference fit is adopted between described male cone (strobilus masculinus) contact-segment and inner conical surface contact-segment.
The angle of described male cone (strobilus masculinus) contact-segment is 15-40 °.
The beneficial effects of the utility model are: the pressure adding junction plane, improve the frictional force of junction plane, save bolt cost and later stage O&M cost, ensure that the stability of connection, and have structure feature simple, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1-casting hub, 2-casting main shaft, 1-1-plane contact section I, 1-2-inner conical surface contact-segment, 2-1-plane contact section II, 2-2-male cone (strobilus masculinus) contact-segment.
Embodiment
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As Fig. 1, a kind of novel wind power wheel hub main shaft connection structure, the casting hub 1 that it comprises casting main shaft 2 and is connected with casting main shaft 2, one end of described casting hub 1 is provided with joint I, one end of casting main shaft 2 is provided with the joint II mated with joint I, wherein, joint I is by plane contact section I 1-1 and be connected with plane contact section I 1-1 and the inner conical surface contact-segment 1-2 extended internally forms, joint II is by plane contact section II 2-1 and be connected with plane contact section II 2-1 and outward extending male cone (strobilus masculinus) contact-segment 2-2 forms, male cone (strobilus masculinus) contact-segment 2-2 to insert in inner conical surface contact-segment 1-2 and with inner conical surface contact-segment 1-2 close contact, plane contact section II 2-1 and plane contact section I 1-1 close contact are also bolted.
Interference fit is adopted between described male cone (strobilus masculinus) contact-segment 2-2 and inner conical surface contact-segment 1-2.
The angle of described male cone (strobilus masculinus) contact-segment is 15-40 °.
Compared with existing Placement, utilize inclined-plane to coordinate, when horizontal force is identical, junction plane gradient is larger, and inclined-plane positive pressure is larger, and is greater than horizontal force all the time, when not increasing bolt quantity, can obtain larger frictional force.
Specific embodiment described herein is only to the utility model explanation for example.The utility model person of ordinary skill in the field can make amendment miscellaneous or supplements or adopt similar mode to substitute to described specific embodiment, but can not depart from spirit of the present utility model or surmount the scope that appended claims defines.All employings are equal to the technological scheme of replacement or equivalent deformation formation, all drop on the protection domain of the utility model claim.
