friction-gearing

A worker uses friction-gearing to transfer power between two smooth wheels.

Definition

1. Noun:
   • Mechanical device: "friction-gearing" refers to a system of gears or wheels that transmit motion through friction rather than through interlocking teeth. It is used in machinery to transfer power between rotating shafts by relying on the contact pressure and friction between surfaces.

Usage Examples

• Noun:
  • The engineer designed a friction-gearing system for the conveyor belt to reduce noise. (A mechanical device using friction to transmit motion.)
  • In older lathes, friction-gearing was common to allow smooth speed changes. (A type of gear mechanism that operates by frictional contact.)

Advanced Usage

• "to employ friction-gearing": to use a friction-based transmission system in a machine.

  • The factory employed friction-gearing in its presses to avoid gear damage from sudden loads. (Used a friction-driven mechanism to protect equipment.)

• "friction-gearing ratio": the relationship between the diameters of the friction wheels that determines the speed change.

  • The friction-gearing ratio was adjusted to increase the output torque. (The proportion of wheel sizes affecting rotational speed.)

Variants and Related Words

• Friction gear (n): a simpler term for a single friction wheel or pulley used in such a system.

  • The friction gear on the motor shaft wore out quickly. (A single wheel that transmits motion by friction.)

• Friction drive (n): a broader term for any mechanism that uses friction to transmit power, including friction-gearing.

  • The electric scooter uses a friction drive on the wheel. (A power transmission system relying on friction.)

Synonyms

• Friction transmission: a system that transfers motion through frictional contact.
• Friction wheel: a wheel that drives or is driven by friction.
