This glossary present twenty terms used in industrial mechanics or millwright work. These terms could be useful for trainees and students to learn about mechanics and identify equipment commonly found in an industrial environment. It helps them understand what equipment they are working on or definition of terms that could be hard to interpret.
alignment
noun
Alignment is the process of adjusting machine components so that shafts and parts are straight and correctly positioned to reduce wear and vibration.
Example: Proper alignment reduces vibration and extends bearing life.
en: alignement
bearing
noun
A mechanical component that reduces friction between moving parts.
Example: The bearing allows the shaft to rotate smoothly.
en: roulement à bille
belt drive
noun
A system that uses belts and pulleys to transmit power.
Example: The belt drive transfers power from the motor to the fan.
en: transmission par courroie
chain drive
noun
A power transmission system using a chain and sprockets.
Example: The conveyor uses a chain drive to move products.
en: transmission par chaîne
conveyor
noun
A mechanical system use to moved materials or objects from one place to another.
Example: Boxes are transported on the conveyor.
en: convoyeur
coupling
noun
A device that connects two shafts to transmit motion.
Example: The coupling connects the motor to the pump.
en: accouplement
dial indicator
noun
A precision measuring tool use to check alignment and runount.
Example: A dial indicator is use during shaft alignment.
en: comparateur a cadran
fastener
noun
Hardware such as bolts, nuts, or screws used to hold parts together.
Example: Fasteners secure the guard to the machine.
en: attache / fixation
gearbox
noun
A mechanical system containing gears to change speed or torque.
Example: The gearbox reduces the motor speed.
en: boite d'engrenages / réducteur de vitesse
grease fitting (zerk)
noun
A small fitting used to inject grease into bearings or joints.
Example: Grease is applied through the grease fitting.
en: embout de graissage
lubrication
noun
The application of oil or grease to reduce friction and wear.
Example: Proper lubrifiacation increases machine life.
en: lubrification
millwright
noun
A highly skilled tradesperson specializing in the installation, maintenance, troubleshooting, and repair of industrial machinery and equipment.
Example: The millwright repairs the production equipment.
en: mécanicien industriel
predictive maintenance
noun
Predictive maintenance is a maintenance method that uses data, measurements, and condition monitoring from sensors, to predict when industrial equipment is likely to fail, allowing maintenance to be performed before a breakdown occurs, rather than on a fixed schedule or after failure, maximizing up time and efficiency.
Example: Vibration analysis is use in predictive maintenance to detect bearing problems early.
en: maintenance prédictive
preventive maintenance
noun
A proactive and planned strategy involving regularly scheduled inspections, and repairs to prevent equipment failure.
The process of lifting and moving heavy equipment safely.
Example: Rigging is required to install heavy machine.
en: levage et gréage
runout
noun
A rotating part deviate from true rotation, off-center, or not exactly round.
Example: An excessive runout can generate a lot of vibration in the machine that could affect is lifespan.
en: faux-rond
tolerance
noun
The acceptable variation in a measurement or dimension.
Example: The shaft diameter must be within tolerance.
en: tolérance
ultrasound testing
noun
Ultrasound testing is a diagnostic method that used high-frequency sound waves to detect air leaks, bearings defects, and electrical problems in industrial equipment.
Example: Ultrasound testing is used to locate compressed air leaks in the plant.
en: analyse par ultrason
vibration analysis
noun
Vibration analysis is a predictive maintenance technique that measures machine vibration to identify mechanical problems such as imbalance, misalignment, or bearing failure.
Example: Vibration analysis detected an early bearing failure in the motor.
en: analyse vibratoire
work order
noun
A work order is a document that describes maintenance or repair tasks to be completed on equipment.
Example: The millwright received a work order to repair the conveyor.
