Related representation: [Mechanical gear connection](https://eloragrid.ai/symbols/iec-mechanical-gear-connection) IEEE-library form of mechanical gear connection: a gear-connection indication identifies transmission through a gearing relationship. ## In plain English ### What does ANSI/IEEE Mechanical gear connection form mean? This reference locates mechanical gear connection in Autodesk's IEEE-oriented mechanical controls, coupling family. 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 public library uses Q021223 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number. ### A simple example Read the operating mechanism and the contact reference state together. Cross-reference every associated contact to the same device and show which movement, signal or reset changes its condition; the symbol alone does not establish the complete switching sequence. ### What the drawings help you do The schematic identifies the relationship while a mechanical drawing supplies ratio and geometry. Avoid treating the gear connection mark as a numerical reduction ratio. 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. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted. ### This particular reference IEEE-library form of mechanical gear connection: a gear-connection indication identifies transmission through a gearing relationship. The symbol does not give a gear ratio, tooth geometry or mechanical rating. ### Terms - Normally open / normally closed: The contact state in the normal condition defined for the drawing. - Terminal: An identified point where a conductor connects. - Signal: Electrical information passed between devices, rather than necessarily the main power supply. Concept diagram: Identify the device and form → Read the connections and state → Check the equipment reference A guide to reading this reference. The original symbol illustration and its drawing notes appear below; these boxes are not a wiring diagram. - [Autodesk IEEE Symbol Preview: Mechanical Controls, Coupling](https://help.autodesk.com/cloudhelp/2021/ENU/AutoCAD-Electrical/files/GUID-3B784797-C632-4E0A-BCDC-D7E4D982FE34.htm) ## What it represents This reference locates mechanical gear connection in Autodesk's IEEE-oriented mechanical controls, coupling family.
