Sheave Maintenance

Learning objectives

  • Describe the construction of V-belt sheaves
  • Describe the construction of positive traction belt sheaves
  • Discuss the design and application of manually adjusted, variable speed sheaves
  • Discuss the design and application of spring-loaded, adjustable, variable speed sheaves
  • Explain how to align sheaves using a straightedge
  • State the reason for adjustable sheave lubrication

Course overview

A sheave is a wheel with a grove along its edge for holding a rope, cable, or belt. Sheaves are used in industrial facilities that need to send power from one source to another. Sheaves can change the direction of an applied force, transmit rotational motion, or realize a mechanical advantage in either a linear or rotational system of motion.

The Sheave Maintenance course describes sheaves commonly used on belt drives in industrial facilities, including operation and design. It also explains basic techniques used to maintain them. This course focuses on:

  • V-belts and positive traction belt sheaves
  • Variable speed sheaves
  • Sheave alignment and maintenance

Sheave Maintenance is part of the Introduction to Belt Drive Maintenance training series.
