The second slide surface 442, with the opposite arc damping area 443 of damping 41 inner wall of shell, the radius of curvature and damping of damping area 443
The radius of curvature of disk 42 is identical, and winch axle 22(is shown in Fig. 3 when damping block 44 works along electric capstan) direction of rotation is gradually by big
Become smaller.
There are gaps between first bottom surface 431 and the second bottom surface 441, and between the first bottom surface 431 and the second bottom surface 441
Equipped with pressure spring 410, it is equipped with axis hole 45 in the first bottom surface 431 and the second bottom surface 441, on the first bottom surface 431 and the second bottom surface 441
Two axis holes 45 coaxial arrangement, the both ends of pressure spring 410 are inserted into respectively in corresponding axis hole 45.
It damps shell 41 and is equipped with second bearing seat 46, the second positioning bearing 47 is equipped in second bearing seat 46, second is fixed
Position 47 inner ring of bearing is shown in Fig. 3 with winch axle 22() it is fixedly connected, the second hole retaining ring 48 is additionally provided in second bearing seat 46.
It damps shell 41 and is equipped with protective shell 49, prevent dust from entering in the second positioning bearing 47.
Specific implementation process: clutch tooth axle sleeve 8 is connect with the output shaft transition fit of worm gear case 32, and motor 31 passes through worm gear
Case 32 drives clutch tooth axle sleeve 8 to rotate, and clutch tooth axle sleeve 8 rotates with, and guide pin 912 moves in one-way spiral slot 85, promotees
Clutch tooth axle sleeve 8 is moved downward, clutch tooth axle sleeve 8 is fastened togather with driving cog axle sleeve 7, and drive driving cog axle sleeve 7 to rotate,
The winch axle 22 that driving is connect with driving cog axle sleeve 7 together rotates, and damping block 44 overcomes the elastic force of pressure spring 410 towards first at this time
The movement of 431 direction of bottom surface, the damping area 443 and damping shell 41 of damping block 44 generate lesser resistance, have little influence on capstan winch
Normal work；
When 32 output shaft of worm gear case rotates counterclockwise, close tooth shaft set and separated with driving cog axle sleeve 7, at this point, the elder generation of lead ring 110 to
Right operation, it is ensured that guide pin 912 enters movement in one-way spiral slot 85, promotes clutch tooth axle sleeve 8 to further diverge from until with biography
Movable tooth axle sleeve 7 separates, and promotes clutch tooth axle sleeve 8 to further diverge from until separation, the at this time work of one-way damper 4, wedge shape damping
Block 44 damping area 443 and 6 damping area of clutch shell, 443 friction fit under the action of pressure spring 410, generate damping, prevent
The anchor excessive velocities of whereabouts, cause capstan wheel 2 to invert, and hawser generates winding.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
