The unidirectional torque restraint device comprises the first chain wheel 29 of being fixedly connected with worm gear 28, supports respectively the 3rd spring 31 that is located at casing and the second chain wheel 30 bottoms with the first chain wheel 29 the second chain wheel 30, both ends in mating connection, be formed with the upper surface tooth on the lower surface of the first chain wheel 29, be formed with the lower surface tooth that matches with described upper surface tooth on the upper surface of the second chain wheel 30, worm gear 28 and the first chain wheel 29 empty sets are on screw rod 5, and the second chain wheel 30 can drive screw rod 5 and rotate and can slide up and down along screw rod 5.
Driver train also comprises with the rotating shaft of motor 16 bevel gear wheel 26 that matches the bevel pinion 25 of rotation, matches and rotate with bevel pinion 25, bevel gear wheel 26 is fixedly installed on the worm screw 27, and the axial line of bevel gear wheel 26 is mutually vertical with the axial line of bevel pinion 25.
Principle of work: when the operator wants outboard engine lifted, press the rising button, electromagnet 13 and simultaneously forward energising of 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 rotations by bevel pinion 25, thereby order about worm gear 28 and the first chain wheel 29 to anticlockwise (black arrow direction among Fig. 2), the first chain wheel 29 contacts by facing directly with the end-tooth of the second chain wheel 30, promote the second chain wheel 30 equally to anticlockwise (black arrow direction among Fig. 2), therefore screw rod 5 promotes nut 4 risings (supposing to use right handed screw) to anticlockwise.When nut 4 rises near end cap 2, will rise by pushing drawing rod 3, trigger upper limit position switch 7, cut off the power supply simultaneously for motor 16 and electromagnet 13, 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 the 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 at that time position, reaches the purpose of any adjusting outboard engine height.
When the operator wants outboard engine put down, press the decline button, the simultaneously oppositely energising 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 by bevel pinion gear 25, drive worm screw 27 rotations, so drive worm gear 28 and the first chain wheel 29 to right rotation (white arrow direction among Fig. 2), the end-tooth of the second chain wheel 30 contacts by the inclined-plane with the end-tooth of the first chain wheel 29, because the propulsive effort that descends is less, under the effect of the 3rd spring 31, the first chain wheel 29 still can drive the second chain wheel 30 to right rotation (white arrow direction among Fig. 2), thereby drives screw rod 5 to right rotation, promotes nut 4 declines (supposing to use right handed screw).When nut 4 drops to bottom near cylindrical shell 6, will trigger lower position switch 8, cut off the power supply simultaneously for motor 16 and electromagnet 13, 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 the decline process, if the operator feels to run to correct position, X button at this moment, 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 at that time position.
In the boats and ships traveling process, when outboard engine suffers the energetically bump of water-bed obstacle, strut 1 can be subject to the very large strength that makes progress together with nut 4, thereby try hard to drive the second chain wheel 30 toward anticlockwise (black arrow direction among Fig. 2), although at this moment the first chain wheel 29 and worm gear 28 maintain static (electromagnet 13 is not switched on and is in braking mode), but as long as impact is enough large, the end-tooth of the second chain wheel 30 and the first chain wheel 29 can be along inclined-plane generation slippage, the 3rd spring 31 is compressed, therefore the second chain wheel 30 can move down the engagement of disengagement and the first chain wheel 29, with screw rod 5 to anticlockwise (black arrow direction among the figure), thereby strut 1 is up lifted under the impact effect, avoid causing the damage of outboard engine.Change the elastic force of the 3rd spring 31, can change the threshold value of impact.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present invention and according to this enforcement, can not limit protection scope of the present invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
