Week 21-23: LO 4 Understand power transmissions, principles of operation and failure patterns of GEAR DRIVES

Week 21-23: LO 4 Understand power transmissions, principles of operation and failure patterns of GEAR DRIVES
29.4 Understand power transmissions, principles of operation and failure patterns of
GEAR DRIVES
Lesson Objectives
To discover the principles of operation: tooth profiles, cross-sectional shape, number of teeth, generation of the involute form, the geometry of gears, pressure angles, terms of circular gear geometry, backlash, diametrical pitch and speed relationship between two mating gears
To identify the Types and arrangements of gears: bevel gears, plain, spiral, hypoid, helical, spur, worm
To explore the maintenance requirements of gears: alignment, lubrication and condition
To examine the operating symptoms: noise, overheating and vibration
To recognise the symptoms of gear failure: corrosion, link seizure, wear and galling
To determine the causes of failure: out of alignment, out of parallel, out of plane and contamination
To look at the lubrication of gears: moisture, out of mesh and overload
