Embodiment
Please refer to Fig. 1 to Fig. 6, the unidirectional energy-storage transmission device of vacuum circuit-breaker, comprise energy storage cover 2, an one energy storage axle 1, by energy-storage crank arm connects the energy-stored spring of energy storage axle 1, a cam 3, coordinates cam 3 combined floodgate release, N number of rotary body 4 and an elastomer 5, this N is the natural number of >=2.Among the present embodiment: this energy storage cover 2 connects actuator, energy storage can be driven to overlap 2 to make actuator and rotate, such as energy storage is overlapped 2 outer surfaces and is enclosed within gear pair by key joint, and this energy storage cover 2 is such as steel bushing, drives energy storage to overlap 2 rotate by gear pair; It is motionless when cam 3 is kept by combined floodgate release.
The recessed N number of groove of this energy storage axle 1 outer surface of revolution annular display.This cam 3 is installed with revolution ring seat 31, and this revolution ring seat 31 is established N number of annular display and run through inside and outside breach 32; Among the present embodiment, this cam 3 establishes through hole, and this revolution ring seat 31 is installed in cam 3 end face and around through hole, their dead in line, this through hole flushes with the surface of revolution in revolution ring seat 31.This energy storage axle 1 can rotate and be located in revolution ring seat 31 and through hole, and this energy storage cover 2 can be rotatably connected on outside revolution ring seat 31.
This rotary body 4 selects roller, and rotary body 4, breach 32 and groove one_to_one corresponding are adaptive, and rotary body 4 to be installed in breach 32 and fit.Among the present embodiment, this rotary body 4 selects roller, but not as limit, as required, also can select spheroid.This elastomer 5 selects bullet circle, and connection energy storage axle 1 and rotary body 4 receive outside active force to make rotary body 4, is resisted against the surface of revolution in energy storage cover 2 to make rotary body 4.Among the present embodiment, this elastomer 5 selects bullet circle, but not as limit, as required, also can select spring, in each groove, establish spring, and spring top supports rotary body 4 makes it be subject to outside active force.Wherein: this breach 32 width is greater than rotary body 4 tactical diameter, to make rotary body 4 energy opposed notches 32 movable; The semidiameter of this revolution ring seat 31 is less than rotary body 4 tactical diameter, partly puts in the surface of revolution in revolution ring seat when being resisted against the surface of revolution in energy storage cover 2 to make rotary body 4 by active force.
Wherein:
Turn clockwise, rotated by the frictional force driven rotary body 4 between energy storage cover 2 and rotary body 4, rotary body 4 fit and breach, then can drive energy storage axle, cam turns clockwise together; Be rotated counterclockwise, because energy storage axle establishes energy-stored spring, the moment of resistance is greater than the moment of frictional force, energy storage cover 2 and rotary body is all dallied, energy storage axle cannot be driven to rotate together with cam, realize single-direction transmission;
When cam is kept motionless, energy storage cover 2 is clockwise or be rotated counterclockwise, the moment of frictional force all cannot be with moving cam to rotate, energy storage cover 2 and rotary body all dally, energy storage axle cannot be driven to rotate together with cam, then this cam not only has and transmits the function of spring energy, also has the function being separated carry-over moment between energy storage cover and energy storage axle, is multifunction module (original cam be single realize the transmission of spring energy to major axes orientation).
Among the present embodiment, this groove is divided into workbench 6 and treats machine platform 7.This treats that machine platform 7 is for V-shaped groove, and this workbench 6 is inclined-plane and the side on inclined-plane is connected to the side of V-shaped groove, and the opposite side on inclined-plane is connected to the outer surface of revolution of energy storage axle 1, and this treats that machine platform 7 and workbench 6 are along clockwise layout; When rotary body 4 is positioned at workbench 6, rotary body 4 contacts workbench and acts on inclined-plane; Rotary body 4 is positioned at when machine platform 7, and rotary body 4 and workbench 6 have gap.This breaker energy storage work process is:
Energy storage cover 2 rotates along clockwise direction, and energy storage cover 2 is moved by the frictional force driven rotary body 4 between rotary body 4, makes rotary body 4 leave energy storage axle 1 and treats machine platform 6, enter energy storage axle 1 workbench 7(and be resisted against inclined-plane).Energy storage cover 2 continues to rotate along clockwise direction, and energy storage cover 2 drives energy storage axle 2 to rotate along clockwise direction together with cam 3 by rotary body 4, and energy storage axle 1 drives spring energy-storage by energy-storage crank arm.
After energy storage puts in place, energy storage cover 2 continues to rotate along clockwise direction, cam 3 is kept motionless by combined floodgate release, then rotary body 4 rotates in the counterclockwise direction, make rotary body 4 leave energy storage axle 1 workbench 7 to enter energy storage axle 1 and treat that machine platform 6(is separated with the inclined-plane of workbench 7), energy storage is made to overlap transmission unable between 2 and energy storage axle 1, now: if energy storage cover 2 continues to be rotated in a clockwise direction, also energy storage axle 1 can not be driven to rotate, and (moment of friction cannot be with moving cam to rotate, then energy storage cover 2 and rotary body all dally, energy storage axle cannot be driven to rotate together with cam), if energy storage cover 2 rotates in the counterclockwise direction, rotary body 4 only can be in the machine platform 6 for the treatment of of energy storage axle 1, and (moment of friction cannot be with moving cam to rotate, then energy storage cover 2 and rotary body all dally, and energy storage axle cannot be driven to rotate together with cam), energy storage cover 2 can not drive energy storage axle 1 to rotate.
The above, be only present pre-ferred embodiments, therefore can not limit scope of the invention process according to this, the equivalence change namely done according to the scope of the claims of the present invention and description with modify, all should still belong in scope that the present invention contains.
