Relationship between large subject matter areas

F16D is a general function-orientated place.

Glossary of terms

In this subclass, the following terms or expressions are used with the meaning indicated:

Actuator

A component of a mechanism that causes movement of a motion-conveying component or motion-inhibiting component but does not itself directly convey or inhibit motion.

Brake

A mechanism with at least one component that is moved by an actuator to selectively or automatically engage or stop a member with respect to a stationary part.

Clutch

A mechanism with at least two relatively movable components that are selectively or automatically engaged with each other by control means, e.g. an actuator, to transmit mechanical power or convey motion from a first member to a second member or disengaged by control means to stop transmitting mechanical power or conveying motion.

Coupling for transmitting rotation

A mechanism that transmits torque or conveys rotary motion from a first shaft to a second shaft or other rotating member and that either does not include relatively moving components or, if it has relatively moving components, the components move without the use of control means.

Synonyms and Keywords

Slack adjuster

Wear compensation mechanism, automatic adjuster, automatically adjusting device, automatic adjustment device, self-adjustment device
