Course Description
Reviews fundamentals of bearings, shafts, belt drives, chain drives, sheaves, couplings and lubrication used for precise operation of heavy industrial equipment. Includes industrial torqueing, tensioning, and machine condition monitoring techniques. Covers precision alignment using analog instruments such as a straight edge and dial indicator. Covers precision alignment using digital instruments such as lasers. Includes vibration analysis. Emphasizes safety procedures while working near machinery, especially machinery with high speed rotating parts. Prerequisites: APR 260, and (WR 90 and RD 90) or IRW 90 and MTH 20 or equivalent placement or department permission. Audit available.
Addendum to Course Description
Required Course for Apprentices registered in the Millwright/Industrial Maintenance Technician Program. It is open to any other student but requires Department Permission to take this course.
Intended Outcomes for the course
Upon completion of the course students should be able to:
- Provide precision horizontal plane and vertical plane alignment for machine to machine applications in order to properly operate heavy industrial equipment and to extend the service life of heavy industrial equipment.
- Provide precision horizontal plane and vertical plane alignment for rotating shaft to rotating shaft applications in order to properly operate heavy industrial equipment and to extend the service life of heavy industrial equipment.
- Apply safety procedures and practices when working in proximity to equipment with high speed moving components.
- *Demonstrate the functions of trade-specific industrial systems (*required statewide outcome).
- *欧洲杯决赛竞猜app_欧洲杯足球网-投注|官网 machine shop skills in troubleshooting (*required statewide outcome).
Course Activities and Design
The Course Design is primarily lecture coupled with demonstrations of alignment procedures for heavy industrial equipment, using both digital and analog tools and instruments.
Outcome Assessment Strategies
Assessment will be accomplished using skills' checklists filled out by an adequate sampling of Millwright/Industrial Maintenance Technician Training Agents and/or an Apprentice's Journey Person.
