Embodiment
The composition structure and the principle of accompanying drawing narration contact type electromagnetic driving device of the present invention.To introduce in detail below:
Whole contact electromagnetic driving system distribution situation is equipped with several friction pulley guide rails 12 successively along the curve inner side of friction lever track 1 as shown in Figure 2, and friction pulley guide rail 12 is positioned on the normal direction of friction lever track 1 bend.When friction lever 2 was positioned on the friction lever guide rail 1, the contact type electromagnetic driving device segmentation drove friction lever 2, made its motion and waltzed through the bend of friction lever guide rail 1.
Between friction material layer 3 and core wheel 5, coil windings layer 4 is installed.The absolute coil 14 that coil windings layer 4 is installed by several ringlike constitutes, and its structure as shown in Figure 3.Core wheel 5 rotates under the effect of motor 6 during work, several absolute coils 14 energisings close in the coil windings layer 4 with friction lever 2, produce electromagnetic attracting force friction lever 2, make friction material layer 3 pressing friction bars 2, move along the bend of friction lever track 1 thereby drive friction lever.A plurality of absolute coils 14 among Fig. 3 are along core wheel 5 annular distribution, and absolute coil 14 energising backs produce attraction to the friction lever of irony, drive the friction lever motion when making friction material layer pressing friction bar.
The isostructural movement position of friction pulley that friction pulley guide rail 12 is used to limit installing rack 7 and adheres to.The left end of friction pulley guide rail 12 has a projection 13, is used to limit the limit on the left of installing rack 7 range of movement, and friction pulley guide rail 12 right-hand members have the hard-wired frame 9 that resets, and is used to limit the limit on the right-right-hand limit of installing rack 7 range of movement.Respectively there are an electromagnet 8 and 10 in the installing rack 7 frame 9 corresponding positions that reset, and can control the size and Orientation of electric current separately separately.
When a contact type electromagnetic driving device job, because friction lever 2 moves along friction lever guide rail 1 bend, so friction lever 2 promotes the direction motion of the installing rack 7 of this contact type electromagnetic driving device towards the frame 9 that resets, the some absolute coils 14 with friction lever 2 closely contacts in the coil windings layer 4 produce suction to friction lever 2 under the effect of electric current at this moment, and first electromagnet 10 in second electromagnet 8 of installing rack 7 and the frame 9 that resets, produce a certain size repulsion between the two, under both actings in conjunction, friction material layer 3 pressing friction bars 2 also drive friction lever 2 motions under the effect of motor 6.
Leave the working range of this contact type electromagnetic driving device when friction lever 2 after, first electromagnet 10 in second electromagnet 8 of installing rack 7 and the frame 9 that resets leads to upward electric currents at this moment, make and produce repulsion between the two, frame 9 is fixing owing to reset, so the structures such as friction pulley that installing rack 7 adheres to drive on it stop to projection 13 away from the frame 9 that resets along friction pulley guide rail 12, wait next friction lever 2 to be driven.
Can prevent that also friction lever from skidding off the inclination angle of track when as shown in Figure 1, the contact-making surface of friction lever 2 and friction pulley assembly (3,4,5) has the friction material layer of assurance 3 pressing friction bars 2.
Fig. 4 is the shape of steamboat 11 and friction pulley guide rail 12 under the driving wheel installing rack 7.On the friction pulley guide rail 12 projection is arranged, and the steamboat 11 corresponding Position Design under the installing rack 7 become groove, both agree with mutually, thereby the movement locus of assurance installing rack 7 is in the scope that friction pulley guide rail 12 is set.
