Definition

1. Noun:
   • A flexible band that applies friction to a rotating shaft or drum to slow or stop its motion: A "brake band" is a mechanical component, typically made of a sturdy material like steel lined with friction material, that wraps around a cylindrical part. When tightened, it creates friction to retard or halt rotation.

Usage Examples

• Noun:
  • The mechanic replaced the worn brake band inside the transmission.
  • Applying the parking lever tightens the brake band around the drum.

Advanced Usage

• Technical Context: In automotive engineering, a "brake band" is often a key component in certain types of automatic transmissions and some early braking systems, where it is used to hold a planetary gearset element stationary.

Variants and Related Words

• Band brake (n): A type of braking system that uses a flexible band as its primary friction element; this term is sometimes used interchangeably with "brake band."
• Brake drum (n): The cylindrical surface that the brake band contacts.
• Brake lining (n): The friction material attached to the inner surface of the brake band.

Synonyms

• Friction band: A general term for a band that uses friction to control motion.
• Strap brake: An older term for a similar braking mechanism.

Related Phrases

• To apply the brake band: To activate the mechanism that tightens the band.
• Brake band adjustment: The process of setting the correct tension for proper operation.

Noun

1. a band that can be tightened around a shaft to stop its rotation
