driving-gear
Noun (technical): "driving-gear" refers to a mechanism, typically a set of gears or toothed wheels, that transmits power from one part of a machine to another, especially in engineering or automotive contexts. It is the component that drives or moves other parts.
- (The set of gears transmitting power in the machine.)
- (The gear mechanism responsible for motion transfer.)
"to be in driving-gear": to be engaged or active in transmitting power.
- The machine is now in driving-gear, so be careful. (The power-transmission mechanism is active.)
"to shift driving-gear": to change the gear ratio for different speeds or loads.
- The operator must shift the driving-gear when the vehicle climbs a hill. (Change the gear set to adjust power.)
Driving (adj): relating to the transmission of power or motion.
- The driving shaft connects the engine to the wheels. (The shaft that directly transmits power.)
Gear (n): a toothed wheel that meshes with another to change speed or direction.
- Each gear in the driving-gear set must be properly lubricated. (Individual toothed components.)
- Transmission gear: a gear used for transmitting power.
- Drive gear: a gear that directly receives power from the engine or motor.
- Power train component: a part of the system that transfers power.
"to be in high gear": to be operating at maximum efficiency or speed (figurative use, not directly related to driving-gear but derived from mechanical context).
- The project is in high gear now. (Operating at full speed.)
"to shift gears": to change one's approach or pace (figurative use).
- After the break, we need to shift gears and focus on marketing. (Change strategy.)
This term is highly technical and specific to mechanical engineering, automotive repair, and industrial machinery. It is not commonly used in everyday conversation. In modern contexts, it may be replaced by "drive gear" or "transmission gear."
