The course of work of the utility model embodiment 1 is following: shown in figure 10, big calendar display window 14 numerals show that " 30 " are April 30.Hour wheel 2 CWs rotate, 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 an one, so also counter clockwise direction rotation.Hour wheel 2 circled in per 12 hours, circled in date finger driving wheel 3a24 hour, promptly 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, change a day third wheel 5d and turn over a tooth pitch clockwise so drive be one owing to change a day position wheel 5c and change a day third wheel 5d; Event is changed a day position wheel 5c and is also turned over a tooth pitch clockwise, 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; First change day shifting block 3c and drive and change day third wheel 5d and turn over a tooth pitch more clockwise then; Also turn over a tooth pitch clockwise so change a day position wheel 5c; Because change a day wheel 5c at this moment at weak point tooth place, so mesh with individual position wheel 12, therefore individual position wheel 12 reaches a letter disk 13 and does not rotate.Take turns 5a and ten wheel shafts 10 engagements ten of days and change; Make ten wheel shafts 10 turn over a tooth pitch counterclockwise; Ten of interlock letter disks 11 also turn over a tooth pitch with it, and 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 a tooth pitch counterclockwise; Be May 1, with reference to shown in Figure 12.
Shown in figure 13, big calendar display window 14 shows that " 30 " are March 30.Hour wheel 2 CWs rotate, 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 an one, so also counter clockwise direction rotation.Second changes day shifting block 3d in rotation process; Because of 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 by the course of work that was transformed to 31 on the 30th, with reference to shown in Figure 14; By being transformed to 01 day the course of work on the 31st, with reference to shown in Figure 15 with the above.
The course of work of the utility model embodiment 2 is following: shown in Fig. 1 d; Hour wheel 2 CWs rotate; 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 an one, so also counter clockwise direction rotation.Hour wheel 2 circled in per 12 hours, circled in date finger driving wheel 3a24 hour, promptly 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, change a day third wheel 5d and turn over a tooth pitch clockwise so drive, simultaneously with change calendar indicator 16 that day third wheel 5d is fixed as one from 30 sensings 31; 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; First change day shifting block 3c and drive and change day third wheel 5d and turn over a tooth pitch more clockwise then, at this moment point to 1 from 31, accomplished the solar month of 30 days transfer process with changing calendar indicator 16 that day third wheel 5d is fixed as one.
The course of work of the utility model embodiment 3 is following: shown in Fig. 1 e; Hour wheel 2 CWs rotate; 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 an one, so also counter clockwise direction rotation.Hour wheel 2 circled in per 12 hours, circled in date finger driving wheel 3a24 hour, promptly 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, change a day third wheel 5d and turn over a tooth pitch clockwise so drive, change a day third wheel 5d drive first and change day third wheel 17 and turn over a tooth pitch counterclockwise; Change day third wheel 18 and clockwise rotate and make date rings 19 turn over a tooth pitch this moment second; The numeral that date-indicator window mouth 20 shows becomes 31 from 30, and before second changed day shifting block 3d and planetary gear 4a drop out of gear, first changes a day shifting block 3c began and change day third wheel 5d and mesh; First change day shifting block 3c and drive and change day third wheel 5d and turn over a tooth pitch more clockwise then; Changing a day third wheel 5d drives first once more and changes day third wheel 17 and turn over a tooth pitch counterclockwise; Change day third wheel 18 and clockwise rotate and make date rings 19 also turn over a tooth pitch this moment second; The numeral that date-indicator window mouth 20 shows becomes 01 from 31, has accomplished the solar month of 30 days transfer process.
As shown in Figure 7, the utility model was an one-period with 1 year, and planetary gear 4a has 12 teeth, 7 short teeth wherein, 5 long teeth.Wherein 7 short teeth have 31 days month corresponding respectively 1 year 12 middle of the month; When 30 are transformed to 31; Because of 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 day shifting block 3c and drive and change a day third wheel 5d and turn over a tooth pitch clockwise by first; In the corresponding respectively month (also treated by 30 days February) of having only 30 days of all the other 5 long teeth, 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); So date finger driving wheel 3a rotates counterclockwise when week, change a day shifting block 3d by second earlier and stir planetary gear 4a, because of planetary gear 4a with change a day third wheel 5d interlock; Thereby drive is changed a day third wheel 5d and is turned over a tooth pitch clockwise; Then first change a day shifting block 3c and drive again and change a day third wheel 5d and turn over a tooth pitch clockwise, promptly 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.Like 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 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 following January, and when one month finishes, stir monthly calendar wheel 7 and rotate a tooth pitch, realize related between month and date in the drive of changing day third wheel 5d.
