The course of work of the embodiment of the invention 1 is as follows: as shown in figure 10, big calendar display window 14 numerals show that " 30 " are April 30.Hour wheel 2 clockwise direction are rotated, and drive date finger driving wheel 3a and counterclockwise rotate, because first change that day shifting block 3c and second changes day shifting block 3d and date finger driving wheel 3a is integrated, so also counterclockwise rotation.Hour wheel 2 circled in per 12 hours, circled in date finger driving wheel 3a24 hour, namely first changed day shifting block 3c and second and changed day shifting block 3d and circled in 24 hours.Second changes day shifting block 3d in rotation process, its shifting block is stirred planetary gear 4a and is clockwise rotated, because of planetary gear 4a with change a day third wheel 5d interlock, so band is moved a day third wheel 5d and is turned over clockwise a tooth pitch, be integrated owing to changing a day position wheel 5c and changing a day third wheel 5d, also turn over clockwise a tooth pitch so change a day position wheel 5c, thereby a drive position wheel 12 turns over a tooth pitch counterclockwise; A position letter disk 13 of interlock also turns over a tooth pitch counterclockwise with it, and this moment, big calendar display window 14 numerals were shown as " 31 ", changes moon shifting block 5e this moment and is in the state that is about to engagement with monthly calendar wheel 7, with reference to shown in Figure 11; Before second changed day shifting block 3d and planetary gear 4a drop out of gear, first changes a day shifting block 3c began and changes day third wheel 5d engagement; Then first change day shifting block 3c band and move day third wheel 5d and turn over clockwise again a tooth pitch, also turn over clockwise a tooth pitch so change a day position wheel 5c, owing to change day a position wheel 5c this moment at short tooth place, thus with wheel 12 engagements of individual position, therefore a position wheel 12 and a position letter disk 13 do not rotate.Take turns 5a and ten wheel shafts 10 engagements ten of days and change, so that ten wheel shafts 10 turn over a tooth pitch counterclockwise, ten of interlock letter disks 11 also turn over a tooth pitch with it, this moment, big calendar display window 14 numerals were shown as " 01 ", change a moon shifting block 5e drive monthly calendar wheel 7 this moment and turn over counterclockwise a tooth pitch, be May 1, with reference to shown in Figure 12.
As shown in figure 13, big calendar display window 14 shows that " 30 " are March 30.Hour wheel 2 clockwise direction are rotated, and drive date finger driving wheel 3a and counterclockwise rotate, because first change that day shifting block 3c and second changes day shifting block 3d and date finger driving wheel 3a is integrated, so also counterclockwise rotation.Second changes day shifting block 3d in rotation process, because planetary gear 4a is in short tooth position, thereby can not drives planetary gear 4a and rotate, first change a day shifting block 3c and begin and change a day third wheel 5d engagement subsequently, thereby realize being transformed to 31 days the course of work by 30 days, with reference to shown in Figure 14; The course of work that was transformed to 01 by 31 days is same as above, with reference to shown in Figure 15.
The course of work of the embodiment of the invention 2 is as follows: shown in Fig. 1 d, hour wheel 2 clockwise direction are rotated, and drive date finger driving wheel 3a and counterclockwise rotate, because first change that day shifting block 3c and second changes day shifting block 3d and date finger driving wheel 3a is integrated, so also counterclockwise rotation.Hour wheel 2 circled in per 12 hours, circled in date finger driving wheel 3a24 hour, namely first changed day shifting block 3c and second and changed day shifting block 3d and circled in 24 hours.Second changes day shifting block 3d in rotation process, its shifting block is stirred planetary gear 4a and is clockwise rotated, because of planetary gear 4a with change a day third wheel 5d interlock, so band is moved a day third wheel 5d and is turned over clockwise a tooth pitch, simultaneously with change the calendar indicator 16 that day third wheel 5d is fixed as one and point to 31 from 30, before second changed day shifting block 3d and planetary gear 4a drop out of gear, first changes a day shifting block 3c began and changes day third wheel 5d engagement; Then first change day shifting block 3c band and move day third wheel 5d and turn over clockwise again a tooth pitch, at this moment point to 1 with changing calendar indicator 16 that day third wheel 5d is fixed as one from 31, finished the solar month of 30 days transfer process.
The course of work of the embodiment of the invention 3 is as follows: shown in Fig. 1 e, hour wheel 2 clockwise direction are rotated, and drive date finger driving wheel 3a and counterclockwise rotate, because first change that day shifting block 3c and second changes day shifting block 3d and date finger driving wheel 3a is integrated, so also counterclockwise rotation.Hour wheel 2 circled in per 12 hours, circled in date finger driving wheel 3a24 hour, namely first changed day shifting block 3c and second and changed day shifting block 3d and circled in 24 hours.Second changes day shifting block 3d in rotation process, its shifting block is stirred planetary gear 4a and is clockwise rotated, because of planetary gear 4a with change a day third wheel 5d interlock, so band is moved a day third wheel 5d and is turned over clockwise a tooth pitch, changing day third wheel 5d drives first and changes day third wheel 17 and turn over counterclockwise a tooth pitch, change that day third wheel 18 clockwise rotates so that date rings 19 has turned over a tooth pitch this moment second, the numeral that date-indicator window mouth 20 shows becomes 31 from 30, before second changed day shifting block 3d and planetary gear 4a drop out of gear, first changes a day shifting block 3c began and changes day third wheel 5d engagement; Then first change day shifting block 3c band and move day third wheel 5d and turn over clockwise again a tooth pitch, changing a day third wheel 5d again drives first and changes day third wheel 17 and turn over counterclockwise a tooth pitch, change that day third wheel 18 clockwise rotates so that date rings 19 has also turned over a tooth pitch this moment second, the numeral that date-indicator window mouth 20 shows becomes 01 from 31, has finished the solar month of 30 days transfer process.
As shown in Figure 7, the present invention take 1 year as one-period, planetary gear 4a has 12 teeth, 7 short teeth wherein, 5 long teeth.Wherein 7 short teeth have respectively 31 days month corresponding 1 year 12 middle of the month, when being transformed to 31 from 30 days, because it is in short dentation attitude, second change day shifting block 3d can not with its engagement, so date finger driving wheel 3a rotates counterclockwise when week, only change a day shifting block 3c band by first and move a day third wheel 5d and turn over clockwise a tooth pitch; All the other 5 long teeth are the corresponding month (also treated by 30 days February) of only having 30 days respectively, when being transformed to next month 1 from 30 days, this moment, planetary gear 4a was in long dentation attitude (different long tooth, corresponding different months), when so date finger driving wheel 3a rotates counterclockwise a week, first change a day shifting block 3d by second and stir planetary gear 4a, because of planetary gear 4a with change a day third wheel 5d interlock, thereby band is moved a day third wheel 5d and is turned over clockwise a tooth pitch, then first change a day shifting block 3c and be with again and move a day third wheel 5d and turn over clockwise a tooth pitch, namely change day third wheel 5d and change in succession in day process in this time and turn over two tooth pitches, thereby realize by the conversion to next month 1 on the 30th.Such as Figure 16 ~ shown in Figure 19, expression is the train synoptic diagram of February 30, June 30, September 30, November 30 state respectively, these 4 months identical by the principle that transformed to May 1 in the principle of work that transformed to next month 1 on the 30th and April 30 days, and just planetary gear 4a participates in the long tooth difference of work.
Change moon shifting block 5e and rotate a week in the drive of changing day third wheel 5d in lower January, and when one month finishes, stir monthly calendar wheel 7 and rotate a tooth pitch, realize related between month and date.
