Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Embodiment 1: extremely shown in Figure 8 like Fig. 1; A kind of wind power speed-increasing gearbox with slow driving device; Speedup box adds one-level driving of parallel axes structure for the two-stage Gear Planet Transmission; Comprise casing 23 and be arranged at the output main shaft 2 in the casing 23, the rear side of casing 23 is provided with big end cap 5, and output main shaft 2 has through bolt near the end of big end cap 5 one sides and drives gearwheel 3 slowly.
The end face outside of big end cap 5 is fixed with motor reducer 8, is provided with in the output sleeve 24 of motor reducer 8 and drives axle 6 slowly, drives axle 6 slowly and is connected first flat key 7 and output sleeve 24 Spielpassung through first flat key 7 with output sleeve 24.Because between first flat key 7 and the output sleeve 24 be Spielpassung,, drive spools 6 slowly and can in output sleeve 24, do axial motion therefore when driving spools 6 slowly when receiving axial force.
Slowly drive an axle end of 6 and stretch into the inboard of big end cap 5, inserting end 61 interference fit of driving axle 6 slowly have can with drive gearwheel 3 engagements slowly drive small gear 4 slowly.
As shown in Figure 5, the side of big 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 that stretching out the big end cap 5 first outer ends 101 is fixedly connected with a spanner 17 logical second flat keys 13 with second end, 102, the first ends 101 that place big end cap 5 inboards, and 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 second end 102, and is used to stir the left shifting block 92 and right shifting block 93 that drives small gear 4 slowly, drives small gear 4 slowly 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 through its shaft shoulder and jump ring 11 and vertical shaft 10 axially locating.Therefore, when spanner 17 rotated 10 rotations of drive vertical shaft, shift fork 9 vertical shaft 10 relatively freely rotated, thereby left shifting block 92 or right shifting block 93 are stirred when driving small gear 4 slowly, can contact with driving 4 of small gears slowly, thereby improve the reliability of stirring.
In other embodiments, also can shift fork 9 is fixing through usual manner and vertical shaft 10, connect like welding or bolt, to reach essentially identical technique effect.But owing to adopt welding or bolt to connect, left shifting block 92 or right shifting block 93 are stirred when driving small gear 4 slowly, and drive small gear 4 slowly for line contacts, so the effect of stirring is poor slightly.
Like Fig. 3 and shown in Figure 5, the side of big 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 through 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 the seat board 18 that is fixedly connected with screw 20 through pin 19 with big end cap 5 between spanner 17 and the big end cap 5, seat board 18 is provided with neutral position positioning hole 26 and grade positioning hole 27 of working.Spanner 17 is provided with hinge last 28, is 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, and latch 21 is fixedly connected with the handle 16 that places spanner 17 1 sides.Hinge last 28 is a shoulder hole, and latch 21 is provided with spring seat 29, is provided with pressure spring 15 between the ladder surface of hinge last 28 and the spring seat 29.
The working principle of the utility model is following:
1) when the speedup box proper functioning, the latch 21 on the spanner 17 is arranged in room shelves positioning hole 26, drives small gear 4 slowly 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,, will realize through slow driving device according to the position needs rotating spindle wind wheel several angle of unit fastening system positioning device.At first; To shake hands 16 to mention; Rotating spanner 17 makes to drive small gear 4 slowly and drive gearwheel 3 slowly and reclines; A mode starting electrical machinery retarder 8 that adopts point to start makes and drives small gear 4 slowly and driving gearwheel 3 aligns (tooth top is to teeth groove) slowly, pulls spanner 17 again and is in the normal engaged state to making to drive gearwheel 3 slowly and drive small gear 4 slowly.This moment, latch 21 should be aimed at the work shelves positioning hole 27 on the shift fork seat board 18, put down handle 16, under the effect of pressure spring 15 spring forces, in the firm insertion work shelves positioning hole 27 of latch 21.Simultaneously, limit switch 22 signal triggering, 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 let the safe condition Maintenance and Repair of staff at unit.
More than describe the preferred embodiment of the utility model in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variation according to the design of the utility model.Therefore, all technician in the art according to the design of the utility model on the basis of existing technology through the available technological scheme of logical analysis, reasoning, or a limited experiment, all should be in determined protection domain by claims.
