Description

A kind of adjusting mechanism of mechanical clock pointer

Technical field

The utility model relates to a kind of adjusting mechanism, relates in particular to a kind of adjusting mechanism of mechanical clock pointer.

Background technology

Mechanical clock is that the moment of torsion (or eccentric eccentric torque that hangs the weight generation) that adopts clockwork spring release drives the multi-stage gear engaged transmission, also adopts the pendulum speed regulator that catches that is comprised of escape wheel, escapement lever and escapement (or pendulum) to make transmission gears at different levels have the fixedly mechanical mechanism of velocity of rotation; Gear wherein and wheel shaft separately are fixedly connected, and must have per 12 hours (or 24 hours) revolve the hour wheel that turns around and the time axle, hour hands are installed on the spindle nose; Also must there be per 60 minutes (1 hour) to revolve minute wheel and the split axle that turns around, minute hand is installed on the spindle nose; The second wheel that also can have revolve per 60 seconds (1 minute) to turn around and a second axle are equipped with second hand on the spindle nose.The time, the ratio of gear between the minute, second axle must be changeless (ratio of gear i=60 between second-minute; Minute-time ratio of gear i=12 or 24), clock and watch could work instruction time.

The time, the minute, second axle rotating speed determine by catching pendulum speed regulator speed governing; Determine when hunting period and the escape wheel number of teeth of pendulum (or escapement), the ratio of gear between escapement wheel shaft and second axle (or split axle) is fixed; For example: pendulum (or escapement) swings one, and (that is: hunting period) time is 1 second back and forth, the escape wheel number of teeth is 20, so, the escape wheel time of turning around is: 1*20=20 second (catch the characteristic of swinging mechanism: the pendulum swings one back and forth, escape wheel only turns over a tooth); Ratio of gear between escapement wheel shaft (20 seconds/circle) and second axle (60 seconds/circle) just is fixed as i=20/60=1/3; Only in this way, clock and watch could work instruction time.

If the time of clock pointers indication did not conform to the standard time (Beijing time), just need to adjust pointer indication angle position, make its indicating positions corresponding with the standard time; But because each gear and axle all are to be fixedly connected and to mesh in the clockwork, can't rotate separately and adjust a certain position, therefore just need to install adjustable mechanism arrangement additional.This mechanism is exactly a kind of adjusting mechanism that does not affect the clock and watch normal operation that will install additional.

Mechanical clock is to adopt the mechanical mechanism that the pendulum speed regulator is controlled the multilevel gear drive mechanism uniform rotation that catches that fixing vibration period is arranged, and be designed with in the mechanism: the ⑴ per minute revolves second axle that turns around, and a second pointer fixedly is housed on the spindle nose; ⑵ per hour revolve the split axle that turns around, and a minute pointer fixedly is housed on the spindle nose; ⑶ per 12 hours (or 24 hours) revolves the time axle that turns around, pointer when fixedly being equipped with on the spindle nose; When clockwork normally moves, the time, the every minute and second pointer is by the rotation of separately speed of rotation, instruction time.When pointer instruction time and standard time (Beijing time) not simultaneously, just need to adjust the indication angle of pointer, make it identical with the standard time.

The pointer adjustment of existing machinery clock and watch is: install transmission clutch additional catching the pendulum speed adjusting gear and be equipped with between the gear mechanism of pointer, when needs are adjusted pointer, manually stir clutch coupling, after making the gear mechanism that catches the pendulum speed adjusting gear and pointer is housed break away from joint transmission, manual rotation pulling needle handle rotates and adjusts pointer indication angle again; Adjust completely, manually stir again clutch coupling, make and catch pendulum speed adjusting gear and the gear mechanism joint transmission that pointer is housed, the clock and watch normal operation.But there is following problem in present adjusting mechanism: when adjusting the clock pin, affect the clockwork normal operation; Be unfavorable for implementing (maybe can't realize) electronic adjustment or automatically adjusting pointer.
