principle of work: when operator wants outboard engine to lift, press raise button, the forward energising simultaneously of electromagnet 13 and motor 16, brake plate 14 is attracted toward left movement by electromagnet 13, leave brake disc 15, motor 16 drives bevel gear wheel 26 and worm screw 27 to rotate by bevel pinion 25, thus order about worm gear 28 and the first chain wheel 29 to anticlockwise (in Fig. 2 black arrow direction), first chain wheel 29 contacts by facing directly with the end-tooth of the second chain wheel 30, promote the second chain wheel 30 same to anticlockwise (in Fig. 2 black arrow direction), therefore screw rod 5 is to anticlockwise, promote nut 4 and rise (supposing to use right handed screw).When nut 4 rises to close to end cap 2, will rise by pushing drawing rod 3, trigger upper limit position switch 7, to motor 16 and electromagnet 13 power-off simultaneously, brake plate 14 compresses brake disc 15 under the effect of the first spring 12, so strut 1 rests on vertex, outboard engine is lifted.
in uphill process, if operator feels to run to correct position, at this moment X button, motor 16 and electromagnet 13 are de-energized simultaneously, brake plate 14 compresses brake disc 15 under the effect of the first spring 12, strut 1 will rest on position at that time, reaches the object regulating arbitrarily outboard engine height.
when operator wants outboard engine to put down, press decline button, electromagnet 13 and motor 16 be oppositely energising simultaneously, brake plate 14 is attracted toward left movement by electromagnet 13, leave brake disc 15, motor 16 drives bevel gear wheel 26 by bevel pinion gear 25, worm screw 27 is driven to rotate, so drive worm gear 28 and the first chain wheel 29 to right rotation (in Fig. 2 white arrow direction), the end-tooth of the second chain wheel 30 and the end-tooth of the first chain wheel 29 pass through contact of incline plane, because the propulsive effort declined is less, under the effect of the 3rd spring 31, second chain wheel 30 still can drive to right rotation (in Fig. 2 white arrow direction) by the first chain wheel 29, thus drive screw rod 5 to right rotation, promote nut 4 and decline (supposing to use right handed screw).When nut 4 drops to the bottom close to cylindrical shell 6, will trigger lower position switch 8, to motor 16 and electromagnet 13 power-off simultaneously, brake plate 14 compresses brake disc 15 under the effect of the first spring 12, so strut 1 rests on nadir, outboard engine is put down.
in decline process, if operator feels to run to correct position, at this moment X button, motor 16 and electromagnet 13 are de-energized simultaneously, and brake plate 14 compresses brake disc 15 under the effect of the first spring 12, and strut 1 will rest on position at that time.
when in boats and ships traveling process, when outboard engine suffers the shock energetically of water-bed obstacle, strut 1 can be subject to very large strength upwards together with nut 4, thus try hard to driving second chain wheel 30 toward anticlockwise (in Fig. 2 black arrow direction), although at this moment the first chain wheel 29 and worm gear 28 maintain static (electromagnet 13 is not energized and is in braking mode), as long as but impact is enough large, the end-tooth of the second chain wheel 30 and the first chain wheel 29 can along inclined-plane generation slippage, 3rd spring 31 is compressed, therefore the second chain wheel 30 can move down the engagement of disengagement and the first chain wheel 29, to anticlockwise (in figure black arrow direction) together with screw rod 5, thus strut 1 is up lifted under impact effect, avoid the damage causing outboard engine.Change the elastic force of the 3rd spring 31, the threshold value of impact can be changed.
above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
