Definition

1. Noun:
   • A mechanical power-transmission component: A "driving-belt" is a flexible loop of material (such as rubber, leather, or fabric) used to transmit rotational motion and power from one rotating shaft (the driver) to another (the driven) in machinery. It typically runs between two pulleys.

  • He replaced the worn driving-belt on the lathe to restore smooth operation. (He installed a new belt that connects the motor to the tool.)
  • A loose driving-belt can cause slippage and reduce efficiency. (If the belt is not tight, it may not transfer power effectively.)

Advanced Usage

  • The old factory machines were all driven by a central driving-belt system. (The machines received power from a single belt connected to a main engine.)
