Put 5 to move linearly vertically, so as to ensure that the stability in the moving process of speed change ring 3.It is it should be noted that new in this practicality
In a little embodiments of type, pressing device can be that straight-tube shape can also be the cone cylinder shape for having certain taper, for example, in input shaft
11 sides, it is illustrated that right side, diameter diminishes, and deformation is bigger during so as to realize that speed change ring 3 runs to the region, bores itself and planet
It is also just bigger to take turns at 252 small ends (i.e. less one end of size) contact area, is skidded so as to reduce speed change ring 3, it is not superfluous herein
State.
Further, with reference to shown in above-mentioned Fig. 1 to Fig. 3, process that buncher of the present utility model transmits in power
In, central sun gear 13 drives driven planetary gear 251 to rotate (rotation) afterwards with the synchronous rotary of input shaft 11 (rotation), makes row
Star cone pulley 252 is also synchronously rotated.Because planetary cone wheel 252 is connected with speed change ring 3, and speed change ring 3 does not rotate and (pressed
Tight device 5 is fixed), therefore, during planetary cone wheel 252 rotates (rotation), it can be in speed change ring 3 around speed change ring 3
Center rotating (revolution), and then, because planetary gear shaft 253 passes through planet carrier 23, so planet carrier 23 and planet carrier can be driven
Output shaft 21 on 23 is rotated (rotation), realizes the transmission of power.

Under, the axial-rotation of screw mandrel 41 (i.e. rotation) of speed change screw body 4 is driven by speed changing control mechanism first, screw mandrel 41 can after rotating
Moved so that feed screw nut 42 is upper in the first direction.Because pressing device 5 and feed screw nut 42 are integrally formed, therefore, dress is compressed
Putting 5, equally with feed screw nut 42, (X-direction in Fig. 1) is mobile in a first direction.And then pressing device 5 promotes speed change ring 3 to make change
The conical shell fragment 31 of fast ring 3 is rolled on the surface of planetary cone wheel 252 in the first direction.In order to clearly to speed change ring
The running orbit of conical shell fragment illustrates, and Fig. 4 shows buncher of the present utility model speed change in speed-change process
Movement locus schematic diagram of the conical shell fragment of ring on planetary cone wheel.Wherein, Fig. 4 is schematically with one on speed change ring 3
Illustrated exemplified by conical shell fragment 31.Specifically, as shown in figure 4, when the (X-axis in such as Fig. 4 in the first direction of pressing device 5
Direction) promote speed change ring 3 when, the conical shell fragment 31 of speed change ring 3 is rotated centered on ring center axle 32 (such as Fig. 4 arrows institute
Show) while, along the surface scrolls of planetary cone wheel 252, and then, making speed change ring 3, (X-direction in such as Fig. 4) is mobile in the first direction,
Therefore, the buncher during speed change, its speed change ring using rolling form, compared to existing mechanical stepless
The steel band of automatic transmission (CVT) used in speed-change process slideably for, have frictional resistance smaller and can realize
The advantages that quick speed change.
And then diameter is different on the path that speed change ring 3 is rolled in the first direction due to planetary cone wheel 252, therefore,
The deceleration or acceleration of buncher can be realized.In the embodiment shown in fig. 1, due to the direction upper planet cone along X-axis
The diameter of wheel 252 gradually increases, and the angular speed of two planetary cone wheels 252 is constant, planetary cone wheel 252 and the phase of speed change ring 3
The linear velocity of the position of engagement increases because of the increase of its diameter, therefore, rotation (revolution) of the planetary cone wheel 252 in speed change ring 3
Speed accelerate, by planetary gear shaft 253 promote planet carrier 23 accelerate rotate, and then realize output shaft 21 accelerate output turn
Speed.On the contrary, speed change ring 3 can make the rotating speed of output shaft 21 slack-off after being rolled along the direction opposite with X-axis.
Further, in the embodiment shown in Fig. 1 and Fig. 2, the buncher also includes a housing 6.Wherein, OK
Star power transmission mechanism, speed change ring and variable-speed unit may be contained within housing 6.
In summary, the embodiment with reference to shown in above-mentioned Fig. 1 to Fig. 4, the variable speed that the utility model embodiment provides
By being rotated around it by the planet slave unit ring of power input part driving power output block in device, drive power defeated with this
Go out the output shaft rotation of part, the transfer mode of the transmission moment of torsion can effectively increase power transmission, meet high pulling torque operating mode need
Ask.
Transmitted in addition, the buncher also controls speed change ring to move along the first direction by variable-speed unit with adjusting power
The rotating speed of the power output part of mechanism realizes the speed change of buncher, wherein, in speed-change process, because speed change is including multiple
The conical shell fragment that can be rotated centered on ring center axle, therefore, speed change ring in a first direction move during with rolling
Dynamic form planetary cone wheel surface move, compared to existing mechanical stepless automatic speed changer (CVT) steel band in speed-change process
Middle use slideably for, have the advantages that frictional resistance is smaller and quick speed change can be realized.Also, with reference to the planet
After the structure of cone pulley, not only multiple planetary cone wheels can transmit moment of torsion simultaneously, and the speed change ring is in pressing device and planetary cone wheel
Common extruding is lower to be deformed, increase and planetary cone wheel contact area, thus also have contact area is big, service wear is small, the life-span compared with
The advantages that long.The structure of the buncher also avoid using hydraulic compressing device complicated in existing buncher, from
And there is the advantages that manufacture is relatively simple, and cost is relatively low, and reliability is higher.
Although the utility model is disclosed as above with preferred embodiment, but it is not limited to the utility model.This
Utility model person of ordinary skill in the field, do not departing from spirit and scope of the present utility model, it is various when that can make
Change and change.Therefore, the scope of protection of the utility model is worked as and is defined depending on the scope that claims are defined.
