Embodiment
The invention will be further described below in conjunction with drawings and Examples:
Embodiment 1: extremely shown in Figure 8 such as Fig. 1, a kind of wind power speed-increasing gearbox, speedup box is that the two-stage Gear Planet Transmission adds one-level driving of parallel axes structure, comprise casing 23 and the output main shaft 2 that is arranged in the casing 23, the rear side of casing 23 is provided with large end cap 5, and output main shaft 2 ends near large end cap 5 one sides have been bolted drives gearwheel 3 slowly.
The end face outside of large end cap 5 is fixed with motor reducer 8, is provided with in the output sleeve 24 of motor reducer 8 and drives slowly axle 6, drives slowly axle 6 and is connected by the first flat key 7 with output sleeve 24, the first flat key 7 and output sleeve 24 Spielpassung.Owing to being Spielpassung between the first flat key 7 and the output sleeve 24, so when driving slowly axle 6 and be subject to axial force, driving slowly axle 6 and can in output sleeve 24, do axial motion.
Slowly an end that drives axle 6 stretches into the inboard of large end cap 5, inserting end 61 interference fit of driving slowly axle 6 have can with drive slowly gearwheel 3 engagements drive slowly small gear 4.
As shown in Figure 5, the side of large end cap 5 is provided with positioning hole 51, is provided with " L " shape vertical shaft 10 in the positioning hole 51.Vertical shaft 10 comprises the second end 102 that stretches out the first end 101 outside the large end cap 5 and place large end cap 5 inboards, and first end 101 is fixedly connected with a spanner 17 logical the second flat keys 13, and the second end 102 is provided with shift fork 9.
As shown in Figure 4, shift fork 9 comprises the coupling shaft 91 that is connected with the second end 102, and is used for stirring left shifting block 92 and the right shifting block 93 that drives slowly small gear 4, drives slowly small gear 4 between left shifting block 92 and right shifting block 93.
In the present embodiment, coupling shaft 91 and vertical shaft 10 Spielpassung, and coupling shaft 91 is by its shaft shoulder and jump ring 11 and vertical shaft 10 axially locating.Therefore, when spanner 17 rotated 10 rotation of drive vertical shaft, shift fork 9 can freely rotate relative to vertical shaft 10, thereby left shifting block 92 or right shifting block 93 are stirred when driving small gear 4 slowly, can contact with driving slowly 4 of small gears, thereby improve the reliability of stirring.
In other embodiments, also can shift fork 9 is fixing with vertical shaft 10 by conventional methods, connect such as welding or bolt, to reach essentially identical technique effect.But owing to adopting welding or bolt to connect, left shifting block 92 or right shifting block 93 are stirred when driving small gear 4 slowly, and drive slowly small gear 4 for line contacts, so the effect of stirring is slightly poor.
Such as Fig. 3 and shown in Figure 5, the side of large end cap 5 is provided with limit switch 22, and first end 101 end faces of vertical shaft 10 are fixedly connected with cover cap 12 by screw 14, are fixed with the boss 25 that can contact with the probe of limit switch 22 on the cover cap 12.Therefore, but during vertical shaft 10 rotation, cover cap 12 also can be with vertical shaft 10 rotations, thereby make the probe contact of boss 25 and limit switch 22 on the cover cap 12 or separate.
Be provided with between spanner 17 and the large end cap 5 with large end cap 5 by the seat board 18 that pin 19 is fixedly connected with screw 20, be provided with neutral position positioning hole 26 and a work shelves positioning hole 27 on the seat board 18.Be provided with hinge last 28 on the spanner 17, be provided with the latch 21 that can insert in neutral position positioning hole 26 or the work shelves positioning hole 27 in the hinge last 28, latch 21 is fixedly connected with the handle 16 that places spanner 17 1 sides.Hinge last 28 is shoulder hole, is provided with spring seat 29 on the latch 21, is provided with Compress Spring 15 between the ladder surface of hinge last 28 and the spring seat 29.
Working principle of the present invention is as follows:
1) when speedup box works, the latch 21 on the spanner 17 is arranged in room shelves positioning hole 26, drives slowly small gear 4 and drives gearwheel 3 slowly and stagger, and is in not engagement, and limit switch 22 signals do not trigger.
2) when shutdown is safeguarded, according to the position needs rotating spindle wind wheel several angle of unit fastening system positioning device, will realize by slow driving device.At first, to shake hands 16 to mention, rotating spanner 17 makes to drive slowly small gear 4 and drive gearwheel 3 slowly and reclines, the mode starting electrical machinery retarder 8 that adopts point to start, make to drive slowly small gear 4 and drive gearwheel 3 slowly to align (tooth top is to teeth groove), pull again spanner 17 and be in normal engagement to making to drive slowly gearwheel 3 and drive small gear 4 slowly.This moment, latch 21 should be aimed at work shelves positioning hole 27 on the shift fork seat board 18, put down handle 16, under the effect of Compress Spring 15 spring forces, in the firm insertion work shelves positioning hole 27 of latch 21.Simultaneously, limit switch 22 signals trigger, and slow driving device is in running order, and master control system must not start unit.Starting electrical machinery retarder 8, driving speedup box output driving shaft 2 rotates, thereby drive the rotation of speedup box input shaft 1, main shaft, wheel hub and wind wheel, make the unit locking device can aligned position after locked unit, finally allow the safe condition Maintenance and Repair of staff at unit.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can design according to the present invention make many modifications and variations.Therefore, all in the art technician all should be in the determined protection domain by claims under this invention's idea on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment.
