## Symbol convention

Convention: IEC
Form: Mechanical gear connection
Autodesk IEC-60617 Symbol Preview — Mechanical coupling qualifiers; vendor family reference, not certified IEC geometry or database identifier.

A gear-connection indication identifies transmission through a gearing relationship.

## What it represents

A gear-connection indication identifies transmission through a gearing relationship. A gear relationship transfers motion through the documented gearing arrangement. It can relate an operating member to a switch, position device or driven mechanism.
The schematic identifies the relationship while a mechanical drawing supplies ratio and geometry. Avoid treating the gear connection mark as a numerical reduction ratio.

## How to read it

- State the driving/driven mechanism and any required ratio in the schedule.
- The symbol does not give a gear ratio, tooth geometry or mechanical rating.

## Information to show or reference

- Identify the associated device, circuit or diagram boundary.
- State the driving/driven mechanism and any required ratio in the schedule.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.

## Important distinction

The symbol does not give a gear ratio, tooth geometry or mechanical rating.
