Introduction to Drive Pulley

Design and Working Principle of Drive Pulley

  • The drive pulley is designed to transmit power from the belt to the shaft in a drive system.
  • It typically consists of a cylindrical shell, end discs, bearings, shaft, and locking elements.
  • When the belt moves, it causes the pulley to rotate, transferring power to the driven components.
  • The drive pulley is essential for the smooth operation of various industrial applications.
