Abstract

A kind of arrangements for speed regulation that are used for mechanical clock are to improve mechanical clock punctual timing degree and stability.Be characterized in the additional centrifugal fly weight governor motion of forming by spring and fly weight on the escapement of the wheeled clock and watch of existing mechanical pendulum, perhaps under the pendulum of mechanical pendulum hammer clock, settle a spring, thereby play the automatic speed regulation effect.The present invention is applicable to new mechanical clock design, also is applicable to old mechanical clock repacking.

Description

Automatic speed adjusting device for mechanical clock and watch (CN)

The present invention relates to a kind of arrangements for speed regulation of mechanical clock, particularly relate to a kind of automatic speed governing device that is used for stabilizing mechanical formula clock and watch governing system precision.

Mechanical clock is a tautochronism principle design of utilizing pendulum, its governing system has two kinds of balance wheel type governing system (table and small-sized clock) and pendulum governing systems (relatively large clock), and the accuracy when clock and watch are walked is regulated escapement hairspring or pendulum jib-length and disposable setting when it dispatches from the factory or keeps in repair.When the condition of the condition when using when setting up has difference (as wearing and tearing, lubricating condition variation, temperature variation, effect of magnetic influence, hairspring wear out, clockwork spring degree of tightness and external impacts etc.), then must cause the extra time error of walking.So, reach quite high degree even clock and watch are adjusted the punctual timing degree when setting up, always but suitable error is arranged during actual the use.Now the general provision mechanical type wrist-watch that newly dispatches from the factory allows error 30～45 seconds every day.After using the long term, its error also can increase.

Task of the present invention is to provide a kind of additional clock and watch arrangements for speed regulation, the caused time error that adds away of condition difference when condition is with setting when reducing the clock and watch use, the punctual timing degree and the stability of raising mechanical clock.

Be to realize the foregoing invention task, the present invention is the centrifugal arrangements for speed regulation that additional springs and fly weight are formed on the escapement of clock and watch, perhaps connects spring and be connected with cantilever elasticity on the pendulum of clock.Like this, because the centrifugal force that swing produced of escapement or pendulum, make fly weight depart from core wheel and move or make pendulum press down the change jib-length.Condition when using changes when accelerating when making away; The escapement rotating speed increases, and fly weight departs from the mobile increase of core wheel, increases the moment of inertia of escapement, thereby makes escapement return to former setting rotating speed; Perhaps the swing speed when pendulum increases, and the power of the downward pressing spring of pendulum increases, and cantilever is increased, thereby make the swing speed of pendulum return to former definite value.Condition when using changes when making away when slack-off, and its mechanism also reaches the former setting speed that returns to above-mentioned opposite.Speed when the present invention promptly utilizes centrifugal fly weight speed control principle to realize walking of self-setting clock table improves punctual timing degree and stability.

Below in conjunction with accompanying drawing the present invention is described in further detail:

Fig. 1 is the automatic speed governing device preferred plan synoptic diagram that the present invention is used for the balance wheel type mechanical clock.

Fig. 2 is the automatic speed governing device preferred plan synoptic diagram that the present invention is used for the pendulum mechanical clock.

Referring to Fig. 1, the automatic speed governing device that the present invention is used for the balance wheel type mechanical clock is placed in escapement (1), it is made up of fly weight (2) and sheet spring (3), sheet spring (3) is clamped in the groove of pin (4), pin (4) is fixedlyed connected with escapement, the chucking position of moving sheet spring (3), elasticity that can the trimmer spring, sheet spring (3) roughly meets at right angles with core wheel pin line.This automatic speed governing device also can be made up of the extension spring of radially settling along escapement or stage clip and pouring weight, can reach effect same.

Referring to Fig. 2, the automatic speed governing device that the present invention is used for the pendulum clock is to go up at the setting nut (8) of cantilever (6) to settle a stage clip (7), and pendulum (5) is supported on the stage clip (7).This automatic speed governing device also can be designed to the extension spring of any part serial connection at cantilever, can reach effect same.

Advantage of the present invention is obvious, as long as at the additional above-mentioned automatic speed governing device simple in structure of existing mechanical clock, can improve punctual timing degree and stability, can be used for the clock and watch of new design, also can be used for reequiping old clock and watch.
