    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




    • Video 1:

      Here is a video showing chain drive installations and maintenance of the drives

    • Here is information on all you need to know for chain drives that covers the criteria for the unit.

    • Activity 1

      Please read through the PowerPoint on the different types of chain drives

    • Please read through the PowerPoint on the different types of chain drives

    • Activity 2

      Using the previous PowerPoint on the different types of chain drives, please complete the Chain drives worksheet and upload when completed.

    • Here is a good resources on a trouble shooting guide for chain transmission and fault finding.
