Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole realities Apply example.Embodiment in based on this utility model, those of ordinary skill in the art institute under the premise of creative work is not made The every other embodiment for obtaining, belongs to the scope of this utility model protection.

Embodiment：Referring to Fig. 1 to Fig. 6, a kind of lever type variable-speed regulator, including drivewheel and driven pulley, and connection two Feed belt between person, the feed belt are trapezoidal V-belt 5 for cross section；The drivewheel and driven pulley are can The structure that wheel radius are changed by slide unit, it include the V-groove coordinated with V-belt 5 and V-groove fix directly or Connect passive catch bar 3, and the slide unit being hinged with catch bar 3 in succession, also include radially entering slide unit The spacing stopping means of row；

The drivewheel includes rotating shaft 8, slidably connects two symmetrically arranged cross slide blocks 9, and cross in rotating shaft 8 9 four end of shape slide block is respectively hinged a catch bar 3, and 3 end of corresponding catch bar is hinged on the two ends of same V-groove A10 bases, And four V-groove A10 sides are a quarter sector.

Preferably, the driven pulley is identical with active wheel construction.

Preferably, the driven pulley includes that a fixed disc 2, the center of fixed disc 2 are set in an input shaft 1 On, a slip annulus 4 is also arranged with input shaft 1, is evenly arranged with some catch bars 3 on the slip annulus 4, and both it Between be hinged, the other end of each catch bar 3 is hinged the axially vertical expansion link 6 of and input shaft 1, and expansion link 6 sets Put in fixed disc 2 radially, the top of each expansion link 6 is fixedly installed a V-groove B7 mated with V-belt 5； Slip annulus 4 is hinged with one end of catch bar 3, and expansion link 6 is hinged with the other end of catch bar 3, and expansion link 6 and slip annulus 4 are mutually perpendicular to.

Preferably, being radially provided with some emanant through holes mated with expansion link 6 on the fixed disc 2.

Preferably, being slidably connected between the slip annulus 4 and input shaft 1, i.e., slip annulus 4 can be on input shaft 1 Slide axially, cannot but relatively rotate.

The first drivewheel is identical with driven wheel structure, when the cross slide block 9 of drivewheel is close to each other, by promoting Bar 3 makes V-groove A10's to be located away from rotating shaft 8, and the integral radius of such drivewheel are just amplified；So as to cause 5 tensioning of V-belt, The pressure that the V-groove A10 of so driven pulley is subject to increases, and then makes the compression cross of catch bar 3 slide block 9 slide in rotating shaft 8 It is relatively distant from, driven pulley radius will shrink.Drivewheel drives driven pulley by V-belt 5, the cross slide block 9 of drivewheel with Rotate with rotating shaft 8 and slide axially thereon, cross slide block 9 is moved to the position of V-groove A10 by catch bar 3, four The position of individual V-groove A10 simultaneously away from or near rotating shaft 8, the integral radius of such drivewheel are just zoomed in or out, are realized stepless Speed change.The situation principle of driven pulley elder generation stress is the same, and order is contrary.

During using second drivewheel, when the cross slide block 9 of driven pulley is close to each other, V-groove is made by catch bar 3 A10 is located away from rotating shaft 8, and the integral radius of such drivewheel are just amplified；So as to cause 5 tensioning of V-belt, such drivewheel The pressure that is subject to of V-groove B7 increase, the expansion link 6 connected on each V-groove B7 is just relatively fixed the inner chamber of disk 2 and shrinks, And the catch bar 3 that 6 end of expansion link is hinged is subject to thrust, so as to push slip annulus 4 along input shaft 1 to two ends open, so as to lead Cause drivewheel reduced radius.

Input shaft 1 is rotated, and drives slip ring to rotate, and catch bar 3 is rotated with slip ring, and V-groove drives V-belt 5 to rotate. Mobile slip ring, catch bar 3 are advanced, and are changed the radius and girth of speed change disk itself, are reached and be input into the pass being directly proportional to output System.

The buncher overall structure in a minute surface, within one minute surface as bicycle chain.Power transmission is not Interrupted, simple structure, it is easy to keep in repair is suitable for various power apparatus.

Solve the problems, such as due to speed disk as the change of radius girth during rotation becomes slack conveyer belt.Due to speed change Disk is changing its girth, so load transfering strip can only be used to transmit power with frictional force.Speed disk radius change, power transmission belt sag, Radius size must be converted simultaneously using two speed disks for this, keep load transfering strip not relax, it is to avoid frictional force cannot not enough reach Arrive output effect.

Preferred embodiment of the present utility model is the foregoing is only, not in order to limit this utility model, all at this Within the spirit and principle of utility model, any modification, equivalent substitution and improvements that is made etc. should be included in this utility model Protection domain within.
