Mechanical Systems and Power Transmission

MEC 120 introduces students to the fundamental principles and practical applications of mechanical power transmission systems. The curriculum covers key components such as gears, various belt and chain drives, bearings, and couplings, detailing their construction, operational characteristics, and common failure modes. Emphasis is placed on proper installation techniques, including precision alignment, lubrication, and routine maintenance procedures critical for ensuring system efficiency and longevity. Through a combination of theoretical instruction and hands-on activities, learners will gain the necessary competencies to diagnose issues, perform corrective actions, and contribute to the reliable operation of industrial machinery. This course prepares individuals for entry-level technician roles involving the upkeep and service of diverse mechanical equipment.
