Common little cylinder diameter petrol engine does not generally dispose speed change gear at present, even the configuration speed change gear generally also all adopts the gearbox of fixed speed ratio, can't realize automatic stepless speed change, once also there were research institution and manufacturer that this is made efforts, but also do not have good way to realize the automatic stepless speed change of little cylinder diameter petrol engine so far.
Three, summary of the invention
At the disadvantage of above-mentioned existence, problem to be solved in the utility model just provides a kind of simple and compact for structure, slewing range is big, dynamic structure is unaffected, cost is low automatic stepless speed-changing device.The technical solution adopted in the utility model is to realize automatic stepless speed change by the drive mechanism that changes former belt pulley, it comprises casing assembly, clutch disassembly, driving shaft, driven shaft, output sprocket, clutch disassembly is fixed on the driving shaft, fixing bottom-plate, lining and fixed tray successively on the described driving shaft, lining is provided with mobilizable drive plate, constitute inner chamber between base plate and the drive plate, inner chamber is provided with centrifugal ball, and fixed tray and drive plate constitute the V-arrangement circumferential groove; Fixedly install fixed tray on the described driven shaft, set gradually movable disk on the axle sleeve of fixed tray and compress elastic component, fixed tray and movable disk constitute the V-arrangement circumferential groove, and driving belt is connected between the two V-arrangement circumferential grooves.The described elastic component that compresses is made up of spring seat, retaining spring and fixed base.
Move axially only in order to ensure the movable disk on the driven shaft, can not rotate, described movable disk be axially arranged with guiding groove, be provided with guide finger in the guiding groove, guide finger is fixed on the axle sleeve of fixed tray.
In order to improve speed ratio, described driven shaft is provided with the gear that is mated, and fixing output sprocket on the output shaft of gear is realized automatic speed changing and fixing speed change two stage speed change.
In order to prolong the working life of drive plate, described drive plate be axially arranged with the anti-wearing liner that cooperates with lining.
In order to ensure safe operation and overall image, described casing assembly is provided with case.
After adopting said structure, drive plate on the driving shaft is in the position between automatic adjustment and the fixed tray under the centrifugal ball centrifugal action, promptly regulate the width of V-arrangement circumferential groove automatically, make the position of driving belt contact V-arrangement circumferential groove produce change, thereby change the working diameter of driving belt; Movable disk on the driven shaft is under the driving belt tension simultaneously, overcome the elastic force that compresses elastic component, make the position of movable disk produce change, driving belt is produced at the position of driven shaft V-arrangement circumferential groove change, thereby changed the working diameter of driving belt, realized automatic stepless speed change; Have characteristics such as simple and compact for structure, that slewing range is big, dynamic structure is unaffected, cost is low.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Five, embodiment
Shown in Figure 1, specific embodiments for the utility model automatic stepless speed-changing device, it comprises casing assembly 2, clutch disassembly 1, driving shaft 8, driven shaft 14, output sprocket 22, clutch disassembly 1 is fixed on the driving shaft 8, driving shaft 8 and driven shaft 14 are separately positioned on the casing assembly 2 by bearing, drive driving shaft 8 rotations by clutch disassembly 1, pass through driving shaft nut 9 fixing bottom-plate 3 successively on the described driving shaft 8, lining 10 and fixed tray 7, lining 10 is provided with movable drive plate 4, constitute inner chamber between base plate 3 and the drive plate 4, inner chamber is provided with centrifugal ball 11, and fixed tray 7 constitutes the V-arrangement circumferential groove with drive plate 4; Fixedly install fixed tray 12 by driven shaft nut 15 on the described driven shaft 14, set gradually movable disk 13 on the axle sleeve of fixed tray 12 and compress elastic component, fixed tray 12 constitutes the V-arrangement circumferential groove with movable disk 13, and driving belt 6 is connected between the two V-arrangement circumferential grooves.The described elastic component that compresses is made up of spring seat 18, retaining spring 17 and fixed base 27, and fixed base 27 is fixed on the axle sleeve of fixed tray 12.Can move axially in order to ensure 13 of the movable disk on the driven shaft 14, can not rotate by relative fixed dish 12, described movable disk 13 be axially arranged with guiding groove 26, be provided with guide finger 16 in the guiding groove 26, guide finger 16 is fixed on the axle sleeve and driven shaft 14 of fixed tray 12.In order to improve gear ratio, described driven shaft 14 is provided with the gear 19 that is mated, and passes through fixedly output sprocket 22 of jump ring 21 on the output shaft 20 of gear 19, and gear 19 is fixed on casing assembly 2 by bolt 23.In order to prolong the working life of drive plate 4, described drive plate 4 be axially arranged with the anti-wearing liner 5 that cooperates with lining 10.In order to ensure safe operation and overall appearance, described casing assembly 2 is provided with case 25.
Working procedure of the present utility model is as follows: when faster rotational speed, the speed that clutch disassembly 1 drives driving shaft 8 rotations also improves thereupon, the centrifugal ball 11 of inner chamber produces the centrifugal force increase between base plate 3 and the drive plate 4, the mobilizable drive plate 4 of centrifugal ball 11 extruding, make the position of driving belt 6 contact V-arrangement circumferential grooves produce change, the rotating diameter of driving belt 6 on driving shaft 8 increases; Meanwhile, the pulling force of driving belt 6 is delivered to the movable disk 13 on the driven shaft 14, movable disk 13 overcomes the elastic force that compresses elastic component and produces displacement, make driving belt 6 produce displacement to the center in the position of driven shaft 14V shape circumferential groove, the rotating diameter of driving belt 6 on driven shaft 14 dwindles, on two V-arrangement circumferential grooves, produce new balance up to driving belt 6, thereby realize automatic stepless speed change.Otherwise, when the speed of clutch disassembly 1 drive driving shaft 8 rotations slows down, can realize the purpose of automatic stepless speed change equally.The utility model is under the constant situation of dynamic structure, realizes automatic stepless speed change by the drive mechanism that changes former belt pulley, and dynamic structure is unaffected, and is simple and compact for structure, and it is convenient to transform; Adopt automatic stepless speed change and fixing speed change two stage speed change, slewing range is big.
