Course Description

Course Aims To train course members to a level of skill and understanding of mechanical drives and mechanisms. (ENTRA Module Segment J.502.) Course Objective By the end of the training, course members should be competent to: Be aware of health and safety hazards associated with this type of work Identify defects in bearings, seals and drives using visual, tactile and audio means. Identify the cause of the defect, decide whether the part should be replaced now, or whether it can it be postponed until a convenient time. Remove old bearings and seals, replace with new components. Identify the old components and order replacements Dismantle and overhaul basic gearbox and reduction drive units Align shafts and couplings Remove and refit pulleys and sprockets, correctly align pulleys and sprockets. Fit and tension belts and roller chains. The Course Covers Practical Safety - Before starting any work, locking off isolators, pulling fuses and hanging notices. Recognizing bearing and seal defects Removing plain, ball and roller bearings, Cleaning up old bearings and seals. Dismantling and re-assembling gear trains. Removing cams - Examining for wear - Replacing cams. Practice removing and refitting guards Work on clutches and brakes. Shafts - bearings and couplings - Alignment. Removing and refitting pulleys and sprockets - Checking true running and Alignment. Removing and refitting belts and roller chains - Tensioning of belts and chains. Removing and refitting springs. Theory Electrical isolation - switches and fuses. Notices. Noise, excessive clearance, oil leakage. Containment of lubricants, pullers and drifts. Bearing and seal marking systems - Information needed to re-order Types of gears and gearing in common use Theory of cams and their action The law relating to the guards and their use Dial test indicators Dog clutches, friction clutches and brakes. Flat belts. Vee belts. Roller chain sizes. Retaining methods, keys, keyways, key seats. Compression, tension and flat springs. Methods of applying tension - Jockey pulleys and sprockets.
