Abstract
The utility model relates to a novel structure of quartz large clock movement. On the basis of mechanical clock movement, the utility model changes a spring into that one or two stepping motors are used as a prime motor. The utility model alters components in a transmission system appropriately and is added with a pressure friction pulley on the end face of a division wheel. Thereby, the utility model balances the gravitational moment produced by a big arrow self and makes the length of a minute hand driven by the movement reach to 0.8 meter and the diameter of a clock face enlarge to 2 meter. Besides, the function of the movement is that the time is 12 hours as an hour hand has a single rotation or is 24 hours per single rotation by the change of the drive ratio.
Description
The utility model relates to the big clock movement of a kind of novel quartz (being called for short big clock movement).
System machine mechanical block (extension) clock movement (abbreviation mechanical clock core), its travel time system is a motive power with the clockwork spring, passes to oscillatory system through train, keeps pendulum and makes continuous vibration, and drive minute hand system instruction time, when the last clockwork spring of clock only can be walked 15 days or 30 days.The output torque of this movement is less, only is applicable to drive short and small type pointer.When directly dialling the pin adjustment with hand during the time, require only to make the minute hand system gear to rotate, and can not influence the motion of power train gear, thereby reed is housed at the minute wheel end face.But the friction force that this reed produced is very little, when can only balance short and small, gravitational torque that minute hand produced.
The purpose of this utility model provides the big clock movement of the Long pointer of the long-term continuous working of a kind of energy.
The utility model is based on mechanical clock core, with CMOS integrated package outputting oscillation signal, with two or a stepper motor as prime mover.For increasing the pressure of minute wheel end face upper reed plate, set up the pressure friction pulley, thus the gravitational torque that the huge pointer of balance self produces.Because big clock movement minute hand system moment is big, when the time of adjustment, can't directly dial pin with hand, in big clock movement, set up handsetting mechanism for this reason.
By the change of ratio of gear, the function of big movement is increased in addition.Both can whenever be turned around by hour hands is 12 hours, and also can whenever turn around is 24 hours.
The utility model is compared with the existing mechanical clock movement, and its outstanding advantage has:
1. the clockwork spring of former mechanical clock core replaces with CMOS integrated package and stepper motor, and mechanical oscillation is changed into electric oscillation, has improved timekeeping performance, when realizing walking automatically;
2. owing to increased the pressure friction pulley, driving torque and damping torque are all increased, so minute length that is driven by movement can reach 0.8 meter, the clock face diameter increases to 2 meters;
3. the handsetting mechanism of setting up makes the adjustment time more convenient;
4. have 12 hours systems and two kinds of functions of 24 hours systems.
Below in conjunction with embodiment the utility model is further described.
Accompanying drawing is the structural representation of quartzy big clock movement.Number in the figure is represented respectively: the 1.CMOS integrated package; 2. stepper motor; 3. rotor gear; 4.5.6.7.8.19. be the train gear; 9. minute wheel; 10. dial minute wheel; 11. minute wheel pivot; 12.13. be 24 hours systems hour wheel and transmission gears; 14. be 12 hours system hour wheels; 15. transmission wheel; 16.18. be third wheel; 17. back gear; 20. pressure friction pulley; 21. reed.
By CMOS integrated circuit 1 output electric signal, drive two or a stepper motor 2, drive rotor gear 3, be delivered to minute wheel 9 and minute wheel pivot 11 by the gear in the train 4,5,6,7,19,8, on minute wheel pivot 11, fixed third wheel 16,, passed at last on the hour wheel 14 through back gear 17.During driving, the minute hand transmission drives hour wheel 14, and at this moment hour hands turned around just expression through 12 hours.If cogged 13 in addition on the hollow shaft sleeve of hour wheel 14, with another hour wheel 12 engagements, at this moment hour hands whenever turned around just expression through 24 hours by gear 13, carried out and made timing in 24 hours.Pressure friction pulley 20 and reed 21 are housed on minute wheel pivot 11, and the end face of pressure friction pulley 20 is close to minute wheel 9 end faces, makes it increase friction force, during in order to balance, the gravitational torque of minute hand.Needle shaft one end of dialling of handsetting mechanism is provided with elastic device, pushes to transmission wheel 15 and is fixed in and dial minute wheel 10 engagements on the minute wheel pivot 11, just can adjust the time with dialling pin, and it is complete to dial pin, and transmission wheel is resetted, the load when alleviating operate as normal.
