Category 3
Pendulum according to the power source is divided into two types.
--- Heavy hammer;
--- Spring style.
Wind-up can be divided into the following categories.
a) Direct formula;
b) are wheeled force.
4 Requirements
4.1 Reliability
4.1.1 pendulum movement with fixed bell housing should be reliable, no parts fall off phenomenon, and normal needle injection and on the bar (hammer).
4.1.2 pendulum clock in the upper bar (hammer) period specified in Table 1 should not stop and go, it has not stopped the pendulum clock timekeeping function reported phenomenon.
Table 1 continued to go in days
On the bar (hammer) cycle
Continuation of the travel time
Spring style
Direct forces are wheeled formula
Heavy Hammer
31 33 - -
1517--16
