Abstract
The utility model relates to a vibration motor whose amplitudes can be modulated without stopping. The rotor shaft of the existing vibration motor is made into a hollow axle with an inner spline. A spiral spline shaft which is rotated with the hollow shaft at the same speed is arranged in the hollow shaft. The spiral spline shaft can move to left and right. One of two blocks which are is fixedly connected to each end of the rotor shaft of the vibration motor is connected with the spiral spline shaft by a spiral spline sleeve, which forms the spiral pair of the spiral spline to enable an eccentric block to movably modulate. One end of the vibration motor is provided with a minitype amplitude modulating motor which can drive the spiral spline shaft to move to left and right. By the guide of a spiral groove, a movable eccentric block is forced to correspondingly rotate to the eccentric block which is fixed on the rotor shaft of the vibration motor, which alters exciting force, and realizes the purpose that the vibration motor does not stop to modulate the amplitudes.
Description
The utility model relates to a kind of vibrating motor with push-button switch adjusting amplitude, especially can regulate amplitude under the non-stop-machine situation of vibrating motor.
At present; the vibrating motor of domestic production is each fastening a pair of eccentric block at the two ends of motor special armature spindle; though there is the relative position of several adjustment eccentric blocks to change amplitude, need after shutdown, manually to tear open the machine adjustment, the loading, unloading operation is inconvenience very; influence is produced; and amplitude modulation only divides limited several grades, is difficult to make vibratory equipment to obtain suitable amplitude and other vibration parameters; therefore, consumes energy is many.
The purpose of this utility model provides a kind of vibrating motor, and it can under non-stop-machine situation, be pressed a button and start the amplitude of amplitude modulation motor, adjusting vibrating motor according to producing needs, and amplitude can infinitely be transferred to maximum from zero.
The purpose of this utility model is achieved in that makes the internal spline hollow shaft with the armature spindle of existing vibrating motor, adorns a helical spline shaft with the speed rotation in this hollow shaft, and this helical spline shaft can move left and right; One of two eccentric blocks that the every end of vibrating motor armature spindle is affixed are connected with helical spline shaft with the helical spline cover, constitute the helical spline screw pair, make the eccentric block activity adjustable; At vibrating motor one end a miniature amplitude modulation motor is installed, its armature spindle is a female hollow shaft, is enclosed within on the external screw thread of helical spline shaft, constitutes the thread helix pair.When regulating amplitude, start the amplitude modulation motor, move, utilize helical spline screw pair driving activity eccentric block relative fixed eccentric block to rotate, change centroidal moment by the secondary helical spline shaft that drives of thread helix, obtain suitable amplitude after, disconnect the amplitude modulation motor power.Because each screw pair has self-locking performance, movable eccentric block is along with the vibrating motor armature spindle turns round with speed, and amplitude keeps definite value, reaches the purpose of electronic dynamic adjustments amplitude.
Owing to adopt such scheme, under non-stop-machine situation, can infinitely regulate the amplitude of vibrating motor by push-button switch, simple in structure; operation rapidly, conveniently; make vibrating motor obtain suitable amplitude and other vibration parameters easily, save the energy, and can realize remote and control automatically.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structure principle chart of the present utility model.
Fig. 2 is the structure chart of amplitude modulation mechanism part.
1-guide vane end stop among Fig. 1,2-amplitude modulation rotor hollow shaft, 3-amplitude modulation motor, 4-helical spline cover, the movable eccentric block of 5-, 6-fixed eccentric block, 7-vibrating motor, 8-vibrating motor rotor hollow shaft, 9-helical spline shaft.
In the accompanying drawings, one end of vibrating motor (7) is adorned an amplitude modulation motor (3), fixed eccentric block (6) is affixed with key and vibrating motor rotor hollow shaft (8), movable eccentric block (5) is enclosed within on the vibrating motor rotor hollow shaft (8) versatilely, is connected with helical spline shaft (9) with helical spline cover (4), constitutes the helical spline screw pair, helical spline shaft (9) is contained in the vibrating motor hollow shaft (8), connect with spline, thereupon with the speed rotation, can move left and right.Amplitude modulation rotor hollow shaft (2) has internal thread, is enclosed within on the end external screw thread of helical spline shaft (9), constitutes the thread helix pair.In order to control stroke, guide vane end stop (1) is housed at amplitude modulation rotor hollow shaft (2) two ends.
During the vibrating motor operate as normal, amplitude modulation rotor hollow shaft (2), helical spline shaft (9), movable eccentric block (5), fixed eccentric block (6) all rotate with speed with the vibrating motor rotor, and amplitude is in definite value.When needing amplitude modulation, start amplitude modulation motor (3), the secondary helical spline shaft (9) that promotes of thread helix moves axially, the Turbo Flora keyway forces movable eccentric block (5) the relative fixed eccentric block (6) that is connected with the helical spline cover to rotate, and changes the angle of two eccentric blocks, and centroidal moment is changed, exciting force is along with change, amplitude is adjusted, and the angle of two eccentric blocks can infinitely transfer to 180 from zero and spend, and amplitude promptly infinitely transfers to zero from maximum.The counter-rotating of amplitude modulation motor, eccentric block can reset.
