Week 19-20: LO 4 Understand power transmissions, principles of operation and failure patterns of CHAIN DRIVES

  • Week 19-20: LO 4 Understand power transmissions, principles of operation and failure patterns of CHAIN DRIVES

    chain

    29.4 Understand power transmissions, principles of operation and failure patterns of 

    CHAIN DRIVES

    Lesson Objectives

    • To discover the principles of operation: chain, pitch, width and roller diameter, sprocket, pitch circle diameter, width and number of teeth, speed of driven sprocket in relation to speed of driver
    • To identify the Types and arrangements of chains: even pitch on chain/uneven number of teeth on sprocket, double pitch chains, tensioners
    • To explore the maintenance requirements of chains: alignment, installation, removal, condition, lubrication, storage and tension
    • To examine the operating symptoms: breakage, noise, whipping, jumping and overheating
    • To recognise the symptoms of chain failure: corrosion, link seizure, wear and galling
    • To determine the causes of failure: adjustment, lubrication, vibration, dirt, overload and worn sprockets
