Abstract
The invention discloses a gravity centrifugal magnetic clutch for a low-starting-current motor, and the clutch comprises a driving gear and a driven gear, wherein a plurality of guide grooves are uniformly arranged inside the driving gear along the circumferential direction, a strong magnet is fixed at an opening of each guide groove, a transmission pin is movably arranged inside each guide groove, a plurality of driven rods which are vertical to the transmission pins are correspondently arranged inside the driven gear along the circumferential direction, and transmission pins maintain a trend moving towards the output shaft of the motor under the magnetic force effect of the strong magnets. When the speed of the motor reaches a rated rotation speed, the centrifugal force of the transmission pins breaks through the magnetic force of the strong magnets, so that the transmission pins moves outwards to drive the driven rods and the driven gear to rotate, and the driven gear is connected with a planetary reduction mechanism driving an output shaft to rotate. Due to the adoption of the gravity centrifugal magnetic clutch, the motor is started at an unloaded state, the starting current of the motor is reduced, the service life of the motor is ensured, and the electric power is saved.
Description
Technical field
The present invention relates to the drive of motor technical field, particularly a kind of centrifugal magnetic clutch of gravity that is used for the low starting current motor.
Background technology
At present at electromechanical integration motor and transmission field, connect complicated, bulky between motor and the transmission mechanism; The transmission power loss is many, and the electric current when motor starts under rated voltage, rated frequency generally is several times as much as rated current; Starting current is 4 times to 7 times of rated current; Big starting current can cause that the motor feels hot, can cause the fluctuation of network voltage, influences the normal use of power consumption equipment.
Just need a kind of simple in structure, starting current is little, the transmitted power loss is little low starting current motor this moment, use better and energy savings to help people.The spy is provided with clutch in motor, make electric motor starting at no-load condition, the little nothing overload of starting current possibility, and when motor speed reached normal speed, the centrifugal magnetic clutch work of gravity drove output shaft again and rotates.Final result is that motor starts at no-load condition, has reduced the electric motor starting electric current, has guaranteed its useful life, conservation of power.
Summary of the invention
The present invention is directed to the deficiency that exists in the above-mentioned prior art, a kind of centrifugal magnetic clutch of gravity that is used for the low starting current motor is provided, make motor start, reduced the electric motor starting electric current, guaranteed its useful life, conservation of power at no-load condition.
Technical scheme of the present invention is achieved in that
A kind of centrifugal magnetic clutch of gravity that is used for the low starting current motor; Comprise the driving wheel that is used to connect rotor inner hole and be connected on the driven pulley of motor output shaft with turning set; Driving wheel is sealed and matched with driven pulley and is connected; The edge circumferentially evenly is provided with a plurality of gathering sills in driving wheel; Opening part at gathering sill is fixed with strong magnetic; In gathering sill, be movably equipped with trundle, in driven pulley, be provided with a plurality of and the vertically disposed follower lever of trundle along circumferential correspondence, described trundle has in the outwards motion and intersect the trend that cooperates with follower lever of the magnetic force of breaking through strong magnetic under the effect of strong magnetic magnetic force during to the motion of motor output shaft direction or at the driving wheel high speed rotating.
As preferably, strong magnetic and gathering sill interference fit, and pass through glue fixing.Strong magnetic can not spun off from gathering sill.
For avoiding rigid shock,, on follower lever, be with the cushion pad that driven pulley is played the protection cushioning effect as preferably.
Adopted the principle of the present invention and the beneficial effect of technique scheme to be:
Be provided with the centrifugal magnetic clutch of gravity in the motor of the present invention, in static or when starting when motor, trundle is securely fixed on the driving wheel through the magnetic force of strong magnetic; When motor meets or exceeds rated speed; The magnetic force that the centrifugal force of trundle is broken through strong magnetic outwards moves, and the trundle that outwards moves forms to intersect and drive follower lever with follower lever and rotates, and rotates thereby drive driven pulley; And driven pulley can connect the planetary gear speed reducing mechanism that links to each other with output shaft, further drives the output shaft rotation again.
