Abstract
The utility model discloses a gravity centrifugation magnetic clutch used for a low starting current motor, which comprises a driving wheel and a driven wheel, several guide grooves are uniformly arranged in the driving wheel along the circumferential direction, a strong magnet is fixedly arranged at an opening of the guide groove, drive pins are provided in the guide grooves in a movable mode, several driven rods vertically arranged to the drive pin are provided in the driven wheel along the circumferential direction, and the drive pins can keep the motion trend towards to a motor output shaft under the strong magnetic force effect. when the motor speed reaches the rated rotating speed, the centrifugal force of the drive pin breakthroughs the strong magnet magnetic force and the drive pin moves outwardly, the driven rod and the driven wheel are driven to rotate, and the driven wheel is connected to a planet deceleration mechanism capable of driving the rotation of the output shaft. The motor can be started without load carrying, the motor starting current is reduced, the service life can be guaranteed and the electric power is saved.
Description
Technical field
The utility model 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 utility model is 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, has made motor start, reduced the electric motor starting electric current at no-load condition; Guaranteed its useful life, conservation of power.
The technical scheme of the utility model is achieved in that
The 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; In driving wheel, along circumferentially evenly being provided with a plurality of gathering sills, be fixed with strong magnetic, in gathering sill, be movably equipped with trundle at the opening part of gathering sill; 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 and the beneficial effect of the utility model of technique scheme to be:
Be provided with the centrifugal magnetic clutch of gravity in the motor of the utility model; Static or when starting when motor; Trundle is securely fixed on the driving wheel through the magnetic force of strong magnetic, and when motor met or exceeded rated speed, the magnetic force that the centrifugal force of trundle is broken through strong magnetic outwards moved; The trundle that outwards moves forms to intersect and drive follower lever with follower lever and rotates; Rotate 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.

Fig. 1 is the syndeton sketch map of driving wheel and driven pulley in the centrifugal magnetic clutch of the utility model gravity.
Embodiment
The embodiment of the utility model is following:
Embodiment: the centrifugal magnetic clutch of the gravity that is used for the low starting current motor of the utility model, as shown in Figure 1, comprise driving wheel 29, driven pulley 28; The edge circumferentially evenly is provided with eight gathering sills 51 in driving wheel 29; Opening part at gathering sill 51 is fixed with strong magnetic 37; In gathering sill 51, be movably equipped with trundle 38, strong magnetic 37 is fixed on through glue and interference fit in the gathering sill of driving wheel 29, and trundle 38 is fixed through the magnetic force of strong magnetic 37 and is connected; The corresponding follower lever 34 that eight transfer torques are set on the driven pulley 28; Follower lever 34 is perpendicular with trundle 38, and follower lever 34 evenly is arranged between eight movable gravity trundles 38 on the driving wheel 29, and through eight trundle 38 transfer torques.
Static or when starting when motor; Trundle 38 is securely fixed on the driving wheel 29 through the magnetic force of strong magnetic 37; When motor met or exceeded rated speed, the magnetic force that the centrifugal force of trundle 38 is broken through strong magnetic 37 outwards moved, and the trundle 38 that outwards moves forms to intersect and drive follower lever 34 with follower lever 34 and rotates; Thereby driving driven pulley 28 rotates; Driven pulley 28 is sealed and matched with driving wheel 29 and is connected, and on follower lever 34, is with the cushion pad 39 that driven pulley 28 is played the protection cushioning effect, and cushion pad 39 is employed in the engineering elastomeric material.Cushion pad 39 and eight trundles 38 are positioned on the driven pulley 28 through jump ring c36.
