Motor-operating mechanism partly is widely used in various circuit breaker industries as the circuit breaker core drive, and its major function is that electric energy is converted into mechanical energy is that the closing of circuit breaker, separating brake (energy storage) provide power.Having a power failure and stand-by power supply when damaging, circuit breaker need drive manually that row closes, separating brake into, and when artificial on/off switch, motor does not separate with circuit breaker, has increased the difficulty of artificial energy storage.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of motor-operating mechanism that circuit breaker is simple to operate when artificial on/off switch, time saving and energy saving electronic or automatic clutch is installed that makes is provided.
According to technical scheme provided by the invention, the motor-operating mechanism of described electronic or automatic clutch, be included in coil brace fixing on the casing, on coil brace, be fixed with electromagnet casing, the electromagnet casing internal fixation has coil windings and static iron core, sliding plug has the iron core hypomere in static iron core, the top ends of moving iron core hypomere is connected with moving iron core epimere, the top ends of moving iron core epimere is fixed with moving iron core catch, be slidingly connected between the top ends of moving iron core epimere and electromagnet casing, the diameter of moving iron core hypomere is less than the diameter of moving iron core epimere, the diameter of moving iron core epimere is less than the diameter of moving iron core catch, is socketed with back-moving spring on the top end face of electromagnet casing and the electromagnet casing between the moving iron core catch; In casing, be rotatablely equipped with back shaft, on back shaft, be installed with driving gear, on back shaft, be in axial sliding connection driven gear along it, be fixed with spline on the back shaft, offer spline on the driven gear, the spline selective binding of the spline of driven gear and back shaft is provided with secondary spring between driven gear and driving gear; Be provided with bearing between the top ends of the bottom of moving the iron core hypomere and driven gear, the inner ring of moving iron core hypomere and bearing offsets, and the outer ring of driven gear and bearing offsets.
On driven gear, offer the mounting groove of being convenient to bearing and the immigration of moving iron core hypomere side direction.
Described bearing is a deep groove ball bearing.
The present invention makes circuit breaker simple to operate when artificial on/off switch, and it is time saving and energy saving to install.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure: this motor-operating mechanism electronic or automatic clutch, be included in coil brace 10 fixing on the casing 5, on coil brace 10, be fixed with electromagnet casing 12, electromagnet casing 12 internal fixation have coil windings 3 and static iron core 4, sliding plug has iron core hypomere 1.1 in static iron core 4, the top ends of moving iron core hypomere 1.1 is connected with moving iron core epimere 1.2, the top ends of moving iron core epimere 1.2 is fixed with moving iron core catch 1.3, be slidingly connected between the top ends of moving iron core epimere and electromagnet casing 12, the diameter of moving iron core hypomere 1.1 is less than the diameter of moving iron core epimere 1.2, the diameter of moving iron core epimere 1.2 is less than the diameter of moving iron core catch 1.3, is socketed with back-moving spring 2 on the top end face of electromagnet casing 12 and the electromagnet casing 12 between the moving iron core catch 1.3; In casing 5, be rotatablely equipped with back shaft 7, on back shaft 7, be installed with driving gear 6, on back shaft 7, be in axial sliding connection driven gear 9 along it, be fixed with spline on the back shaft 7, offer spline on the driven gear 9, the spline selective binding of the spline of driven gear 9 and back shaft 7 is provided with secondary spring 8 between driven gear 9 and driving gear 6; Be provided with bearing 11 between the top ends of the bottom of moving iron core hypomere 1.1 and driven gear 9, moving iron core hypomere 1.1 offsets with the inner ring of bearing 11, and driven gear 9 offsets with the outer ring of bearing 11.
Described bearing 11 is a deep groove ball bearing.
Moving iron core 1 is constituted with moving iron core catch 1.3 by moving iron core hypomere 1.1, moving iron core epimere 1.2.
When work, the electromagnet that moving iron core 1, back-moving spring 2, coil windings 3, static iron core 4 and electromagnet casing 12 constitute get electric after, moving iron core 1 moves downward, push down driven gear 9 and down move by being installed in bearing 11 on the moving iron core 1, make driven gear 9 be unified into an integral body by the spline on the back shaft 7 and transmit moving fortune with driving gear 6.When having a power failure, electromagnet must not electricity, and moving iron core 1 moves upward under the effect of back-moving spring 2, and driven gear 9 is by up motion under the effect that is installed in bearing 11 on the moving iron core 1 and secondary spring 8, thereby driven gear 9 is separated with driving gear 6.
Be connected by bearing 11 between moving iron core 1 and the driven gear 9, driven gear 9 drives are moved iron core 1 and are run up in the time of can avoiding driven gear 9 to combine with driving gear 6.
On driven gear 9, offer and be convenient to bearing 11 and the mounting groove 9.1 that moving iron core hypomere 1.1 side direction move into, make bearing 11 very convenient with the installation of moving iron core 1.
