Lesson 1 - Chain Drives
Topics:
Installing and aligning shafts; Mounting the drive sprockets and chain; Test running; Lubrication; PM; Chain storage; Troubleshooting; Safety
Learning Objectives:
– List four types of chain drives.– Describe the procedure for aligning the driving and driven shafts.– Distinguish between bored sprockets and bushed sprockets and tell how each is mounted.– Tell how a drive chain is mounted on the sprockets.– List four methods of lubrication for chain drives.– Explain both no-load and full-load test running procedures.– Describe the causes of fatigue breaks, tensile breaks, rapid chain wear, roller wear, and side plate spreading.
Lesson 2 - Belt Drives
Topics:
Installing and aligning drives; Mounting sheaves and pulleys; Installing and adjusting V-belts; Idler sheaves; Flat, positive belt drives; Maintenance
Learning Objectives:
– List the three general types of belt drive and explain how they work.– Tell how sheaves and pulleys are mounted and aligned on their shafts.– Explain why all the belts in a multi-belt drive must be replaced at the same time.– Describe two ways of taking up slack in a stretched V-belt.– List three ways of splicing the ends of a flat belt together.– Differentiate between the way positive-drive belts and other types of belt transmit power.
Lesson 3 - Open Gear Devices
Topics:
Aligning and preparing shafts; Handling and mounting gears; Lubricating open gearing; Preventive maintenance; Troubleshooting; Safety
Learning Objectives:
– Explain why open gearing requires special provisions for feeding lubricating oil to its parts.– Describe how to align parallel shafts, intersecting right-angle shafts, and nonintersecting right-angle shafts.– Describe the procedure for aligning worm gearing.– List some of the problems a visual inspection of gearing can uncover.– Describe the appearance and causes of wear, abrasion, corrosion, scoring, pitting, spalling, cold flowing, fatigue breaks, and cracked rims and
webs.
Lesson 4 - Enclosed Gear Drives
Topics:
Preparing the foundation; Installation; Lubrication; Test running; PM; Troubleshooting
Learning Objectives:
– Tell how an enclosed gear drive should be mounted on the floor.– Tell how an enclosed gear drive should be mounted on the framework of a driven machine.– Describe the two methods of lubrication used in enclosed gear drives.– Explain what should be done during the initial run-in, the one-week check, and the thirty-day check.– List four steps you should take to protect an enclosed gear drive that is to be put into storage.– Identify typical nameplate data.
Lesson 5 - Drive Couplings
Topics:
Installing and aligning shaft couplings; Expansion allowance; Lubrication; No-load testing; Installing universal joints; PM
Learning Objectives:
– List three purposes of a coupling.– List the three basic types of coupling.– Explain how to check both the angular and the parallel alignment of shafts.– Tell how a dial indicator is used in precision coupling alignment.– Calculate shim thickness required to align couplings in an angular plane.– Distinguish between couplings that need lubrication and those that do not.– Describe how shaft couplings, spacer couplings, floating shaft couplings, and universal joints are installed.
