Description of the drawings
Fig. 1 is the cross section structure schematic diagram of the embodiment of the present invention.
Specific embodiment
Embodiments of the invention are described in detail below in conjunction with accompanying drawing, but the present invention can be defined by the claims
Implement with the multitude of different ways for covering.
As shown in figure 1, a kind of infinite speed reduction variator provided in an embodiment of the present invention, it includes：
For encapsulating the casing 1 of the internal components of variator, it is assembled by base plate, side plate and top board, in case
The underside wall inner side of body 1（That is base plate）It is provided with the first axle sleeve 2（Its axis hole is communicated through base plate with the external world）, meanwhile, in casing 1
Top wall（That is top board）The position that the centrage of upper and the first axle sleeve 2 coincides is fitted with an output shaft 3；
Worm gear 4 and the worm screw 5 of power input function are played, wherein, worm gear 4 is set on the first axle sleeve 2, in worm gear 4
Top offers the first embedded slot, and worm screw 5 is then through the side walls of casing 1（That is one of side plate of casing 1）And with
Worm gear 4 is meshed；
The centre mount 6 of the top of worm gear 4 is installed in, spindle assemblies is provided with the top surface of centre mount 6, is opened up on bottom surface
The centrage for having speed governing skewed slot 7, speed governing skewed slot 7 intersects with the centrage of centre mount 6（Can be understood as speed governing skewed slot 7 relative to
Centre mount 6 is tilting arrangement）The bottom para-position of centre mount 6 is embedded in the first embedded slot；
The speed change component being set on spindle assemblies, offers the second embedded slot 8 at the top of speed change component；
The cross groove mechanism of the structure linkage function between output shaft 3 and speed change component is realized, it includes main part 9, opens
Cross groove portion 10 on the top surface of main part 9 and the lobe 11 being arranged on the bottom surface of main part 9, the tail end of output shaft 3 with
The para-position of cross groove portion 10 is fitting to connection, and lobe 11 is then embedded in the second embedded slot 8；
For adjusting the speed governing part of the position of the rotation axiss of centre mount 6, speed governing skewback is provided with the top of speed governing part
12, speed governing part is installed on casing 1 by the first axle sleeve 2, and speed governing skewback 12 is then chimeric with the para-position of speed governing skewed slot 7.
Thus, external motor can provide power by connecting worm 5 to whole variator so that worm gear 4 is relative to first
Axle sleeve 2 carries out spinning motion, and then drives output shaft 3 to rotate by centre mount 6 and speed change component, so as to realize power output；
When speed governing skewback 12 is filled up completely with to speed governing skewed slot 7（I.e. under original state）, the centrage of centre mount 6, speed change component
The centrage of centrage and output shaft 3 overlaps on the centrage of worm gear 4, because the spinning motion of worm gear 4 can drive simultaneously
Centre mount 6 and speed governing part are rotated, and centre mount 6 then can drive output shaft 3 to rotate by speed change component, now, whole to become
The state of fast device belongs to a tooth difference reduction box；When adjusting the phase between speed governing skewback 12 and speed governing skewed slot 7 by regulating part
During to position, because speed governing skewed slot 7 is tilting arrangement, then speed governing skewback 12 inserts or is entrenched in position in speed governing skewed slot 7
Difference, the centrage that can cause centre mount 6 occurs the skew of different distance relative to the centrage of worm gear 4, and then when the band of worm gear 4
When dynamic centre mount 6 is rotated, centre mount 6 can drive speed change component to carry out revolution fortune by rotation axiss of the centrage of worm gear 4
It is dynamic to move with planar circumferential, thus, using cross groove portion 10 and the annexation of output shaft 3 so that the rotating speed of output shaft 3 occurs
Change, the infinitely variable speeds for realizing variator are adjusted；Based on this, the centrage of centre mount 6 relative to worm gear 4 disalignment away from
From difference, speed change component revolution-radius can be caused different from planar circumferential moving radius, and then cause the rotating speed of output shaft 3
Difference, with this function of infinitely variable speeds is realized.
Further, it is the effect of guarantee infinitely variable speeds, while simplifying the structure of whole variator, this reality to greatest extent
Apply that the spindle assemblies of example include the second axle sleeve 13 for being arranged on the top surface of centre mount 6 and to be arranged at the second axle sleeve 13 interior and with second
Main shaft 14 of the axle sleeve 13 in decentered distribution, and speed change component then includes internal gear 15, external gear 16 and several circular internal gears
15 equally distributed elastic clamping blocks, the second embedded slot 8 is opened in the top of external gear 16；External gear 16 is socketed on main shaft 14

Side walls inner side and offset with the side of internal gear 15.Thus, internal gear 15 can be pressed by the setting of elastic clamping block
Together on the second axle sleeve 13 so that when being rotated, internal gear 15 can only be put down centre mount 6 on the top surface of centre mount 6
Face circular motion, and the spinning motion of itself can not be carried out；Simultaneously as the setting of external gear 16 can be easy to output shaft 3 and ten
The assembling of word groove mechanism, centre mount 6 can realize turning for output shaft 3 when being rotated using the revolution motion of external gear 16
Dynamic and power output.
To ensure the pressing effect of internal gear 15, the elastic clamping block of the present embodiment includes compression spring 17 and compact heap
18, one end of compression spring 17 is connected with the side walls of casing 1, the other end is connected with compact heap 18, compact heap 18 and internal gear
15 side offsets.
There is no spinning motion while moving on the top surface of centre mount 6 to enable internal gear 15, to ensure
The final planar circumferential movement effects of internal gear 15, the monnolithic case of the internal gear 15 of the present embodiment adopts hexahedro cube structure,
And elastic clamping block amounts to four, four sides of internal gear 15 are pressed respectively.
For ease of carrying out infinitely variable speeds regulation to whole variator, the speed governing part of the present embodiment includes being socketed on the first axle sleeve
Speed governing in 2 covers the 19, speed control rod 20 being socketed in speed governing set 19 and the locks for being locked in speed governing set 19 in first axle sleeve 2
Set 21, speed governing skewback 12 is arranged at the top of speed control rod 20.Thus, being matched somebody with somebody with lock tube 21 using active connections such as nuts
Close, speed governing set 19 is locked to the diverse location in the first axle sleeve 2, so as to adjust or control speed governing skewback 12 speed governing is inserted into
Position in skewed slot 7, with the power output of this final controlled output axle 3.
In addition, to ensure the structural grouping between associated components, and the fine setting of associated components is realized, the present embodiment
