What are the gears called in a clock?

wheel train
In horology, a wheel train (or just train) is the gear train of a mechanical watch or clock.

Are there gears in a clock?

Look closely at any clock face and you can see this arrangement. Because all of these gears are connected directly together, there is no easy way to rewind or set the clock. That is often handled by having a gear that can be slipped out of the train.

How does a clock escapement work?

The escapement is a mechanism in a mechanical clock that maintains the swing of the pendulum by giving it a small push each swing, and allows the clock’s wheels to advance a fixed amount with each swing, moving the clock’s hands forward.

What is a gear mechanism?

Gears are mechanisms that mesh together via teeth and are used to transmit rotary motion from one shaft to another. They are typically mounted, or connected to other parts, via a shaft or base.

How do you cut gears?

The most common gear-cutting processes include hobbing, broaching, milling, and grinding. Such cutting operations may occur either after or instead of forming processes such as forging, extruding, investment casting, or sand casting. Gears are commonly made from metal, plastic, and wood.

How do gears in a clock work?

A clock uses that principle, too, but in reverse, to slow things. To slow rotary motion, you make the drive gear mesh with a another gear that has more teeth. This is the gear to which the minute hand is attached. The hour hand is attached to a gear that rotates at one-twelfth the speed of the minute hand.

How do you adjust an escapement?

Stop the pendulum and bend the crutch near its middle slightly to the right with the needle-nose pliers if the stronger “tick” is to the right. Likewise, if the stronger sound is on the left, bend the crutch slightly to the left. Set the pendulum back into motion and continue listening.

What is an escape wheel on a clock?

In clock: The pendulum. In a pendulum clock an escape wheel is allowed to rotate through the pitch of one tooth for each double swing of the pendulum and to transmit an impulse to the pendulum to keep it swinging.

Is there easy way to rewind clock gears?

Because all of these gears are connected directly together, there is no easy way to rewind or set the clock. That is often handled by having a gear that can be slipped out of the train. When you pull on the stem of a wristwatch to set the watch, that is essentially what you are doing.

How are the gears on a clock set?

The tubular gear shafts are aligned one inside the other. Look closely at any clock face and you can see this arrangement. Because all of these gears are connected directly together, there is no easy way to rewind or set the clock. That is often handled by having a gear that can be slipped out of the train.

What do you need to know about overhauling a clock?

This is a step that many repairmen leave out when overhauling a clock. Once these steps are taken for each and every bearing surface each gear train is put in place between the clock plates and spun to check for smoothness of motion. Each gear is also checked for what is called proper end and side shake as well as depthing.

Can a clock be wound without moving the gear?

When the clock needs to be wound, the Ratchet can be turned counter-clockwise without moving the gear. Then when the weight pulls it clockwise again, it catches on to the pin fixed to the gear, and continues to power the clock. Now comes time to put the hard design process to the test. Cutting the gears.
