It is pierced by by the first axis hole outside shell 1；Capping 2 is packaged in the top of shell 1 and is closely pressed all parts vertically, covers
2 center is equipped with the second axis hole, and driving shaft 3 is pierced by outside capping 2 through the second axis hole.
The basic principle of buncher is driven using friction, big by adjusting the friction radius of transmission parts
It is small to realize different gearratios.Due to the adjustment of this friction radius be it is stepless, free, uniform, can be real
The adjustment change of any gearratio in existing variable range.But relatively, frictional drive has the characteristic that overload is skidded, the torsion of transmission
Square load has larger limitation.Once in the higher heavily loaded environment of load, buncher is easy to skid.
The stacking pressure of the heavily loaded buncher of the present invention in the axial direction is big, and this pressure remained steady, effectively
Ensure the stability of working environment, make between drive 7 and turntable 8 effective frictional drive under a stable pressure.Meanwhile
The quantity of drive 7 can be arranged as required to three to four in two or more, and biography is compressed at the same time by multiple drives 7
Move so as to increase effective skin friction, improve the reliability of transmission.Remain the stepless speed governing characteristic of stepless transmission again at the same time, eliminate
Pause and transition in rhythm or melody sense in speed-change process, improves the adaptability with driving equipment, driving equipment is carried under a more constant operating mode
For power, energy consumption is saved.
Driving shaft 3 is drivingly connected with exterior driving equipment, so as to obtain power, by drive bevel gear 4 with from mantle
Gear 6 drives a plurality of driven shaft 5 to rotate synchronously.The multiple drives 7 being sequentially connected with driven shaft 5 are under the driving of driving shaft 3
Synchronous uniform velocity rotates, drive 7 and 8 frictional drive of turntable, as long as radial direction of the drive 7 along driven shaft 5 in turntable 8 moves up
It is dynamic, then transmission radius will change, so as to reach the effect of variable speed.Drive 7 is to be moved through arrangements for speed regulation complete
Into.
Preferably, bearing, the output shaft 9 and shell 1 are equipped between the second axis hole and driving shaft 3 of the capping 2
The first axis hole between be equipped with bearing, so that it is guaranteed that driving shaft 3 and output shaft 9 still can be smooth turns in the case where being subject to encapsulate pressure
Dynamic, bearing here is preferably using the cone stick bearing for having radial load and axial load ability concurrently.As further excellent
Choosing, the encapsulation overall size of the bearing of the bearing of the output shaft 9 to driving shaft 3 in the axial direction are more than the encapsulation for covering 2 and shell 1
Overall size, and cover pad between 2 and shell 1 and be equipped with rubber ring.Thus, it is possible to being capable of certain compression axis when ensuring the encapsulation of capping 2
Upward all parts, there is provided closely encapsulate pressure, especially ensure fitting closely between drive 7 and turntable 8.
Please refer to Fig.1 and Fig. 2, the arrangements for speed regulation include screw chuck 10, radial positioning seat 11, radial displacement deck 12
With governor gear 13；Screw chuck 10 and radial positioning seat 11 are in disk form, and centre is equipped with through hole, and the surface of screw chuck 10 is opened
Equipped with spiral channel 14, the surface of radial positioning seat 11 radially uniformly offers at least two radial grooves；Every radially sliding
A radial displacement deck 12 is slidably connected on groove, 12 back side of radial displacement deck is equipped with spiral slip teeth, spiral slip teeth engagement
In in spiral channel 14, drive 7 rotates the bottom for being installed on radial displacement deck 12, is fixed with below every radial groove
One driven shaft 5；The outer edge of screw chuck 10 is circumferentially equipped with external tooth 15, external tooth 15 and the engaged transmission of governor gear 13.
The operation principle of arrangements for speed regulation is similar to the claw in lathe, can be with using the spiral channel 14 on screw chuck 10
Radial displacement deck 12 is adjusted on radial positioning seat 11 along moving radially., can meanwhile spiral channel 14 has latching characteristics
Prevent the reaction force of drive 7 in transmission process from causing the displacement of radial displacement deck 12.When needing speed governing, speed governing is rotated
Gear 13 can drive screw chuck 10 to rotate, and radial displacement deck 12 can be slided diametrically under the action of spiral channel 14
Dynamic displacement, so as to drive drive 7 to produce different size of transmission radius.As further preferred, the drive 7 and footpath
To bearing is equipped between displacement deck 12, bearing herein is preferably thrust bearing, is conducive to drive 7 in speed regulation process and keeps
Stable rotating speed.
Preferably, it is respectively equipped with bearing between the driving shaft 3 and screw chuck 10 and radial positioning seat 11.Actively
Axis 3 is equipped with axle journal at one between screw chuck 10 and radial positioning seat 11 at position, the both ends of axle journal are equiped with circle respectively
The sub- bearing of conical stick, on the one hand ensure that clipping room between screw chuck 10 and radial positioning seat 11 away from；On the other hand in axial direction
It is upper to provide axial assembly force for both.
In order to increase the effective skin friction between drive 7 and turntable 8, gearing is improved, preferably, the turntable
8 surface and the surface of drive 7 are equipped with friction plate.
A kind of heavily loaded buncher provided by the present invention, realizes heavily loaded variable transmission, effectively friction is big, transmission
Process is skidded less, and reliable transmission is high, and driving torque is big.It is smaller in power drive device such as motor, engine constant power change
On the premise of realize uniform speed change, power drive device is had notable work to saving energy consumption in a more constant operating mode running
With realizing energy conservation and environmental protection to greatest extent.It is simple in structure, it is readily mass-produced, maintaining is convenient, and cost is relatively low.
