Table of Contents

Chapter 1: Mechanical Brakes and Clutches

Topics: Installing mechanical clutches and brakes; Preparing shafting; Initial lubrication; Providing the power supply; Test running; PM; Safety

Learning Objectives:

  • Explain how friction-type and jaw-type clutches differ in construction.
  • Name the precautions that should be taken when mounting body on a shaft.
  • Explain how to test-run a mechanical clutch with no load.
  • Explain how to install a mechanical brake.
  • Describe the results of improper alignment between driving and driven shafts.
  • Identify the problems that may be indicated by chatter and excessive noise.

Chapter 2: Electric Brakes and Clutches

Topics: Single- and multiple-disc friction clutch; Tooth-type, hysteresis, eddy-current, and magnetic particle clutch; Heat dissipation; PM; Wiring; Safety

Learning Objectives:

  • Describe how single-disc and multiple-disc friction clutches operate.
  • Explain how the principle of hysteresis is applied in electric clutches.
  • List the three basic components of magnetic particle clutch.
  • Differentiate between the static torque, pickup torque, and average torque of a clutch.
  • Identify the problems that may arise in a clutch if its heat is not dissipated.
  • Define decay time, pull-in time, and response time.

Chapter 3: Adjustable-Speed Drives

Topics: Storage and protection of enclosed drives; Handling and leveling enclosed drives; Repairing shafting; Vibration; Lubrication; Test running; PM; Safety

Learning Objectives:

  • List the precautions necessary to provide extra protection for open-type drives.
  • Describe how to install an enclosed-type drive on a concrete floor.
  • Explain how to prepare the shafting when installing a new enclosed drive.
  • Describe the initial lubrication of new adjustable-speed drives.
  • Describe how to test-run an adjustable-speed drive under no load and full load conditions.
  • Name some of the safety rules for working on an adjustable drive.

Chapter 4: Fluid Drives

Topics: Constant and variable-speed couplings; Torque converters; Coupling drive arrangements; Installing fluid couplings; PM, Safety

Learning Objectives:

  • Explain how a fluid drive works.
  • Describe how constant-speed couplings differ from variable-speed couplings.
  • Trace the fluid path through a torque converter using either a drawing or a cutaway.
  • Describe the various ways of mounting a fluid coupling.
  • Explain how to cool the fluid in large couplings.
  • Discuss preventive maintenance procedures for couplings.

Chapter 5: Complete Drive Systems

Topics: Drive with coupling and roller chain, with two flexible couplings, and with right-angle shafts; Installation; PM; Troubleshooting; Safety

Learning Objectives:

  • List the components used in a typical drive system.
  • Name the part of a drive system in which most of the speed reduction occurs.
  • Describe the construction and operation of a shaft-mounted drive.
  • List the protective devices for a drive.
  • Explain the proper maintenance procedures for a drive system.
  • Describe the steps to be taken when troubleshooting a drive system.
