Below with reference to Fig. 1 to Fig. 3, oil pumper permanent magnetic transmission device provided by the invention and oil pumper are described in detail, it is optional embodiment of the present invention, it is believed that those skilled in the art do not change the present invention spirit and content scope in, it is possible to it is modified and polishes.
Refer to Fig. 1 to Fig. 3, the invention provides a kind of oil pumper permanent magnetic transmission device, including permanent magnetic coupling 1, Hooks coupling universal coupling 2 and reductor 7, the motor 4 of oil pumper connects the input side of described permanent magnetic coupling 1, the outlet side of described permanent magnetic coupling 1 connects described Hooks coupling universal coupling 2, and then by the power shaft of reductor 7 described in the transmission of described Hooks coupling universal coupling 2, the output shaft of described reductor 7 connects the reduction box 3 of oil pumper.
Relevant described permanent magnetic coupling 1, described permanent magnetic coupling 1 includes conductor rotor 11 and p-m rotor 12, described conductor rotor 11 connects described motor 4, described p-m rotor 12 connects described Hooks coupling universal coupling 2, in normal operation, the gap between described conductor rotor 11 and p-m rotor 12 is fixed to special value or interval.
In further alternative embodiment, described permanent magnetic coupling also includes torque limit parts 14, and described torque limit parts 14 can act on described p-m rotor 12 vertically.Furthermore, described torque limit parts 14 include and the spacing bearing 141 of described conductor rotor 11 and/or p-m rotor 12 synchronous rotary, and it is connected to the limited block 142 on described spacing bearing 141, described limited block 142 can generation change in location, the effect to described p-m rotor 12 thereby through change in location minimizing and/or elimination under the ordering about of centrifugal force.This effect can refer to p-m rotor 12 is provided an axial active force, thus the gap between conductor rotor 11 and p-m rotor 12 is defined, and provides the overload protection function of moment of torsion.Limited block 142 is ordered about after disengaging p-m rotor 12 by centrifugal force, can get rid of this effect.
In alternative of the present invention, described torque limit parts 14 also include elastic component 143, and described elastic component 143 is connected between described spacing bearing 141 and limited block 142, and described limited block 142 realizes the recovery of position by described elastic component 143.
In embodiment illustrated in Figure 3, described limited block 142 is rotatably connected on described limited support 141.This rotary motion can pass through rotate to spring structure as elastic component 143, to recover position of rotation.Specifically, it is possible to understand that for, which form spring arm, under centrifugal action, limited block 142 can bend an angle, and now permanent magnetic coupling p-m rotor 12 can on axle slidably.Once there is torque loads, it may be achieved torsion protection function.
In other alternative embodiments, torque limit parts 14 can also adopt other structures, a such as limited block 142, its by elastic component 143 along axis connect limited support 141, on the bearing on central shaft 15 or limited support 141 be provided with groove structure, when limited block 142 insertion groove structure, can realizing spacing, along with centrifugal force, limited block 142 moves along a straight line, can releasing slots structure, thus realizing p-m rotor 12 slidably.Therefrom visible, the torque limit parts 4 that the present invention limits are not limited to rotate, and also can be realized by other modes, and the scope that the present invention protects contains it and owns.
