Detailed description of the invention
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so thatUnderstanding in technical staff of the same trade:
As shown in Fig. 1-6, in figure, mark 1-20 is respectively: Timing Belt 1, synchronous pulley 2, shift fork nut 3, butterfly spring 4, thrustBearing 5, sliding sleeve pin 6, sliding sleeve 7, thrust bearing 8, shift fork 9, initiatively varying pitch screw mandrel 10, push rod 11, V-type groove footstock group 12,Power shaft 13, V-shape belt 14, shift fork pin 15, driven varying pitch screw mandrel 16, output shaft 17, kidney slot 18, active reducing wheel hub19, driven reducing wheel hub 20.
Embodiment: the present embodiment object is the active reducing wheel hub 19 identical by structure and passive reducing wheel hub 20Diameter changes, and realizes the infinitely variable speeds from power shaft 13 to output shaft 18 by the frictional traction of V-shape belt 14.
As shown in Fig. 1,2,4, initiatively the reducing process of reducing wheel hub 19 is realized by following structure: initiatively varying pitch screw mandrel 10The left end shaft shoulder on assemble synchronous pulley 2, on synchronous pulley 2, assemble synchronous belt 1. Power shaft 13 and active varying pitch screw mandrel 10Coaxial assembling, sliding sleeve 7 is sleeved on power shaft 13, can slide along the axis direction of power shaft and 13. On sliding sleeve 7, evenly divide16 inner hinges of cloth, the outer hinge of the inner hinge on sliding sleeve 7 and push rod 11 one end forms hinged pair. The two ends of push rod 11 all addThe outer hinge that work is same, the inner hinge of the outer hinge of push rod 11 other ends and V-type groove footstock group 12 left ends forms hinged pair. Sliding sleeve 7On 16 inner hinges on successively as said structure, be connected with push rod 11 and V-type groove footstock group 12. Shift fork 9 is enclosed within initiativelyOn varying pitch screw mandrel 10, can sliding axially along active varying pitch screw mandrel 10. Shift fork 9 enlarged diameter sections radially have on surfaceOne hole, shift fork pin 15 inserts from hole, and the reduced diameter section of shift fork pin 15 is inserted into the initiatively helicla flute of varying pitch screw mandrel 10In, and can in groove, slide to form transmission cooperation. Shift fork 9 reduced diameter section outer surfaces assemble thrust bearing 8, thrust axis successivelyHold 5, butterfly spring 4 and shift fork nut 3. Three sliding sleeve pins 6 insert respectively in three pin holes of sliding sleeve 7, and through power shaftThree kidney slots of 13, make sliding sleeve 7 be connected with power shaft 13. The reduced diameter section of sliding sleeve pin 6 is by thrust bearing 5 and push awayMechanical axis holds 8 two relative faces and clamps, and sees Fig. 3.
As shown in Figure 2, each part on shift fork 9 left sides (except Timing Belt 1 and synchronous pulley 2) becomes from active with symmetric modeThe right-hand member of screw lead Thread 10 is assembled on active varying pitch screw mandrel 10 and power shaft 13 with same relation again. As shown in Figure 4,V-shape belt 14 embeds in the V-type groove in V-type groove footstock group 12, and formation is fixedly connected with.
These part composition driving parts above, slave unit is except replacing initiatively varying pitch with driven varying pitch screw mandrel 16Outside screw mandrel 10, the structure of remaining parts is identical with driving part with assembling mode, so the reducing process of passive reducing wheel hub 22Also identical with active reducing wheel hub 21. As shown in Figure 5,6, the initiatively structure of varying pitch screw mandrel 10 and passive varying pitch screw mandrel 16,Both helicla flute rotation directions are contrary, and initiatively the helicla flute on varying pitch screw mandrel 10 or passive varying pitch screw mandrel 16 is center pairClaim.
Initiatively reducing wheel hub 19, passive reducing wheel hub 20 are all made up of one group of push rod 11 and V-type groove footstock group 12. Push rodOne end of 11 is hinged with band V-type groove footstock, and the other end coordinates with the inner hinge on sliding sleeve 7, and the push rod 11 of a group is to be radiationShape is evenly arranged between V-type groove footstock group 12 and sliding sleeve 7 and forms beveled structure. Initiatively reducing wheel hub 19, passive diameter-changing wheelHub 20 is by the V-shape belt 14 formation rotating Vortex that is connected. On footstock in V-type groove footstock group 12, at least have a V-typeGroove, and be fixed with the V-shape belt matching with V-type groove quantity. V-shape belt 14 is for being company's V-belt or a polywedge bet.
The present embodiment is in the specific implementation: power is inputted from power shaft 13, and power shaft 13 is by the cunning through its kidney slotCover pin 6, drives sliding sleeve 7 to rotate. Sliding sleeve 7 drives initiatively reducing wheel hub of push rod 11, V-type groove footstock group 12 and V-shape belt 14(19) rotate together, V-shape belt 14 drives driven reducing wheel hub 20 rotating in same directions (with active reducing wheel hub 19 direction of rotation phasesWith), and through V-type groove footstock group 12, push rod 11, sliding sleeve 7 drive, power passes to output shaft 18 by sliding sleeve pin 6 etc., completePower transmission.
The speed change of the present embodiment is come in fact by changing the diameter of active reducing wheel hub 19 and the diameter of driven reducing wheel hub 20Existing. Belt 1 drives two synchronous pulleys 2 synchronously to rotate, and two synchronous pulleys 2 drive respectively initiatively varying pitch screw mandrel 10 and drivenVarying pitch screw mandrel 16 rotating in same directions. Be inserted in shift fork pin 15 in varying pitch screw mandrel 10 initiatively along with active varying pitch screw mandrel 10Rotate to centre and slide, shift fork pin 15 drives thrust bearing 8, sliding sleeve pin 6, thrust bearing 5, butterfly spring 4, shift fork nut 3 oneRise and slide to centre. Sliding sleeve pin 6 drives sliding sleeve 7 to slide to centre. When sliding sleeve 7 slides to centre, push rod 11 around with sliding sleeve 7The hinge forming rotates, and V-type groove footstock group 12 is just by jack-up, and initiatively the diameter of reducing wheel hub 19 becomes large. Driven varying pitch screw mandrel16 is contrary with the thread groove rotation direction of active varying pitch screw mandrel 10, along with active reducing wheel hub 19 diameters become large, and driven reducing wheel hub20 diameter diminishes, and V-shape belt 14 remains tensioning state. So just realize between power shaft 13 and output shaft 18 and having passedThe stepless change of moving ratio.
Initiatively the pitch on varying pitch screw mandrel 10 and the pitch on driven varying pitch screw mandrel 16 keep certain variation ruleRule so that the radian that initiatively varying pitch screw mandrel 10 pitch and driven varying pitch screw mandrel 16 rotate respectively with active reducing wheel hub 19Outside dimension D1 and driven reducing wheel hub 20 outside dimension D2 are varied to linear relationship. Under the pitch of varying pitch screw mandrel meetsFormula:
，(0<x<l)
C---reducing velocity coefficient,
The distance of the displacement screw mandrel axis direction plane of symmetry is arrived in x---this position,
L---push rod length.
