Embodiment
Below in conjunction with accompanying drawing concrete structure of the present invention is further described.
Fig. 1 on race ring, be provided with radially or the straight line of axial drilling launch schematic representation.Along same circumference at axial or radially equally spaced a series of gardens taper hole that is provided with, according to the driftage required precision, the hole heart in these holes apart from can be greater than the diameter in hole, equal the diameter in hole or less than the diameter in hole.Fig. 2 is the structural representation of taper pin, and this taper pin can be single tapering taper pin, double tapered taper pin, and perhaps the upper end is the taper pin of sphere.The inside and outside race ring one quiet one of driftage Slewing Support Mechanism is moving.Static race ring and pylon are fixed, and the race ring and the engine room foundation of rotation link together.Garden taper hole and taper pin are separately positioned on the dynamic and static part of driftage Slewing Support Mechanism.
Fig. 3 is the structural representation of the driftage Slewing Support Mechanism of band out yawing gear, and it comprises out yawing gear 1, driftage pivoting support outer bearing ring 2 and driftage pivoting support inner bearing ring 3.
Fig. 4 adopts out yawing gear Slewing Support Mechanism, the taper pin shown in when on inner bearing ring radial hole being set and the position view of pin-and-hole.On the inner bearing ring 3 of described Slewing Support Mechanism, at axial or radially equally spaced a series of gardens taper hole that is provided with, one or more taper pins that match with the garden taper hole 6 and the drive unit 5 that is used to drive the garden taper pin are installed on described tower flanges 4 along same circumference.
Fig. 5 is for adopting out yawing gear Slewing Support Mechanism, the taper pin shown in when on inner bearing ring axial bore being set and the position view of pin-and-hole.On the inner bearing ring of described Slewing Support Mechanism 3, at axial or radially equally spaced a series of gardens taper hole that is provided with, one or more taper pins that match with the garden taper hole 6 and the drive unit 5 that is used to drive the garden taper pin are installed on described tower flanges 4 along same circumference.
Fig. 6 is in adopting during the yaw gear Slewing Support Mechanism, the position view of taper pin and pin-and-hole, shown in the figure is on outer bearing ring 2, at axial equally spaced a series of axial conical bores 7 that are provided with, one or more taper pins that match with the garden taper hole 6 and the drive unit 5 that is used to drive the garden taper pin are installed on pylon 4 along same circumference.
Fig. 7 is when using the brake disc of special setting, the position view of taper pin and pin-and-hole.The Slewing Support Mechanism, engine room foundation, pylon and the brake disc 9 that contain the out yawing gear among the figure, described out yawing gear and brake disc are fixed together, at the axial equally spaced a series of gardens taper hole 7 that is provided with, one or more taper pins that match with the garden taper hole 6 and the drive unit 5 that is used to drive the garden taper pin are installed on engine room foundation 8 at the same circumference in described brake disc upper edge.
Locked in order to prevent taper pin and pin-and-hole, the difficulty that causes taper pin to return can consider that the cone angle of taper pin main body is slightly less than or is slightly larger than the cone angle of taper hole.This moment, taper pin was the line contact with contacting of taper hole.In order suitably to increase area of contact, can be with taper pin top or the suitable chamfering of conical bore end face.Also can on the surface of taper pin, make projection or groove.
The drive unit 5 of taper pin insertion taper hole can adopt hydraulic pressure or electromagnetic coil to power up and drive in the design that spring returns; Also can adopt the design of " failure safe ", promptly spring is pressed into, and hydraulic pressure or electromagnetic coil power up and return.Because this device does not need too big driving force,, under the situation that loses hydraulic pressure or electric power, guarantee the safety of unit so can be easy to realize the design of " failure safe ".
For the driftage rotary supporting device of yaw gear in adopting, taper hole is arranged on the outer bearing ring, taper pin and driving arrangement thereof be installed in inner bearing ring and the relatively-stationary member of interior yaw gear on.The concrete layout according to concrete model structure decided.
Driftage precision and operational instruction
1). when adopting taper pin plug-in type braking device, apart from approximating diameter, the taper hole of 300 30mm diameters can be set on the 9m circumference by the hole heart.At this moment Pian Hang " resolution " is 360/300=1.2 °, and the maximum deviation of driftage control is 0.6 °.General error is between 0～0.6 °.If adopt overlapping taper hole, promptly heart distance in hole is less than diameter, and for example the hole heart then can be provided with the taper hole of 600 30mm diameters apart from approximating radius on the 9m circumference.At this moment Pian Hang " resolution " is 360/600=0.6 °, and the maximum deviation of driftage control is 0.3 °.General error is between 0～0.3 °.If can adopt less braking taper pin diameter, increase the number of braking taper pin simultaneously, then the precision of driftage control can further improve.
2) if. the Off-course Target position makes taper hole and taper pin not align, but deviation is less, relies on the conical surface of taper pin, still taper pin can be advanced to the engaging position.
3). can aim at taper hole more accurately in order to make driftage braking taper pin, so that insert, can consider to adopt control system accurately to control the method for driftage angle, simultaneously at each mounting point, break relevant position sensor, when driftage finishes, to judge whether taper pin inserts, to guarantee the safe and reliable of unit operation.For example, if on circumference uniform 600 continuous holes, the driftage control accuracy be 0.6 °.Go off course 20 ° if desired, then driftage control angle that the cabin is rotated is near 20 ° 0.6 ° integral multiple, that is: 20/0.6=33.3 rounds up, and gets 33, and the angle of driftage control is 33 * 0.6=19.8 °.At this moment driftage augular offset is 0.2 °.
