Fig. 1 has represented that by transmission gear for electric motor basic structure of the present invention, it has a compression spring 2, and spring 2 is pressed on the hollow control lever shaft 1, and can move by the dead point.Be provided with synchronous step bar 3 on control lever shaft 1, the shape of bar 3 is approximately 1/4 circle, which is provided with deep-slotted chip breaker (Figure 1A), inserts hinge bar 4 in the groove, and hinge bar 4 is hinged with lever 6 on the other hand, and lever 6 is contained on the shape plug-in strip axle 5.Control lever shaft 1 can be rotated to support on the shell 7 by means of two bearings, has represented the bearing 8 of transmission side among the figure.Worm gear mount pad 9 is fixed on the shell 7 by bearing 8, and worm gear mount pad 9 has a centre bore and a sliding surface that is used for worm gear 10, and this worm gear 10 has a centre bore equally, worm gear 10 by this centre bore and control lever shaft 1 axially to the heart.Fig. 2 is the profile of worm gear mount pad 9 and worm gear 10 structures, has represented the worm screw 11 of transmission worm gear 10 among the figure.Worm gear 10 has a gap a with respect to worm gear mount pad 9.As seen from Figure 1, worm gear 10 is positioned on the worm gear mount pad 9 by support plate 10a.
The transmission device that is made of worm gear 10 and worm screw 11 links to each other with motor 12 by worm shaft, and wherein worm gear 10 is again simultaneously a rotatablely move part of clutch of control lever shaft 1.Second part of clutch is clutch shaft 13(Fig. 4), it is contained in the control lever shaft 1, and can move axially (Fig. 1), but then is connected with the control lever shaft torsion pass along direction of rotation.For this reason, on clutch shaft 13, be shaped on a groove that parallels to the axis 14, insert a screw 15 that is contained on the control lever shaft in the groove.Clutch shaft 13 passes worm gear mount pad 9, be equipped with on the termination of worm gear one side at it, deviate from beyond the control lever shaft 1 at worm gear 10, a shaft-like actuator 16 is radially arranged in distolateral groove milling, actuator 16 has rectangular cross section, be used for transferring rotational motion, as the part that is shaped as ring of the wall 17 on groove milling border, as the sleeve (Fig. 4 A) of same fluting.A compression spring 19 is housed in this sleeve, and compression spring rests on the actuator 16, and the other end of spring 19 is pressed against on the fixed dam 18.The other end of clutch shaft 13 is fixedlyed connected with slide bar 21.In this zone, in control lever shaft 1, can insert hand operating lever 22, utilize its available hand on slide bar 21, to apply a thrust that overcomes the power of compression spring 19.
At worm gear 10(Fig. 3,3A) deviate from beyond the control lever shaft 1, with two concentric projectioies 20 of hole on, each direction of rotation is had two the stop surface 20a and the 20b of actuator 16.Actuator 16 can rotate with respect to worm gear 10 in the angular range between stop surface 20a and the 20b.Under engagement state, clutch shaft 13 is pressed to worm gear 10 by actuator 16 under compression spring 19 effect, and abuts against on the worm gear 10 in the zone between the stop surface 20a and 20b.
If want the cut-off switch process, then should connect motor 12, so worm gear 10 is rotated along predetermined direction by the rotation of worm screw.Look the difference of rotation direction, actuator 16 is leaned on mutually with stop surface 20a or 20b, thereby clutch shaft 13 is also rotated.At this moment, the compression spring 2 that uses as switch spring by compression, till control lever shaft 1 reached such angular position, by compression spring 2 was in the dead point under this position.Be in the compression spring 2 of corresponding angular position, be connected with control lever shaft 1 by lever dolly 23.After crossing the dead-centre position, spring 2 off-load resiliences, owing between stop surface 20a and 20b, neutral is arranged, thus cause control lever shaft 1 to be rotated further with being similarly phase step type, and make 5 rotations of breaker cutter shaft by hinge bar 4.The speed of phase step type switching process depends primarily on compression spring 2, is identical with irrelevant to rotation direction all the time.If crossed the dead-centre position, then motor is by the break of contact motor at breaker cutter shaft 5 places, and the contact is Be Controlled under the angular position of regulation, and switching process stops.Because the self-locking action of worm gearing, thereby can avoid breaker cutter shaft and thereby the vibration of switchblade knife.
If will manually cut off switching process, then make hand operating lever 22 enter the free end of control lever shaft 1, be pressed on the slide bar 21 that is loaded in the clutch shaft 13, and overcome the power of compression spring 19.So, clutch shaft 13 in control lever shaft 1 along the axis of orientation of compression spring 19 to displacement X, make actuator 16 arrive position with worm gear 10 disengage from.Therefore transmission device and control lever shaft 1 are thrown off.In this course, key 24 on hand operating lever 22 other ends enters in the groove 25 of its stop surface, stop surface is used for two direction of rotation and the free travel of control lever shaft 1, therefore by hand operating lever 22 and thereby control lever shaft 1 along the rotation of respective direction, until crossing the dead-centre position, just can the cut-off switch process.Self-evident, after being inserted control lever shaft 1, hand operating lever 22 handled a switch, and it has cut off the electric current that leads to drive motors 12, handles so can implement manual emergency.
Should mention that also worm shaft is designed to and can connects commercial current various direct currents and AC driven motor and small-sized drive motors by flange.By tilting and the motor of rotation on worm gearing, the volume of whole transmission gear for electric motor and the space that is provided are complementary.
