Worked Solution & Example Answer:9.1 Name THREE aspects that need to be checked during the preventative maintenance of a belt drive system - NSC Mechanical Technology Fitting and Machining - Question 9 - 2020 - Paper 1
Step 1
Name THREE aspects that need to be checked during the preventative maintenance of a belt drive system.
Answer
- Checking for wear and tear on belts: Inspect the belts for signs of fraying or cracking to ensure they remain functional.
- Checking belt alignment: Verify that the belts are correctly aligned to avoid premature wear or failure.
- Checking the tension setting: Ensuring proper belt tension is crucial to optimal performance and longevity.
Step 2
State THREE results of a lack of preventative maintenance on a gear drive system.
Answer
- A loss of lubrication: Inadequate lubrication can lead to increased friction and wear on components.
- Loose components: Parts may become misaligned or loose, affecting the overall functionality of the system.
- Excessive wear on components: Without maintenance, components can experience accelerated wear, leading to failures.
Step 3
Step 4
Describe the procedure to replace the belt on a belt drive system.
Answer
- Switch off the machine: Ensure the machine is powered down to prevent accidents.
- Release the tension on the belt: Loosen or release the mechanism holding the belt under tension.
- Remove the belt from the pulleys: Carefully detach the belt from the pulleys without damaging them.
- Fit the replacement belt onto the pulleys: Make sure the new belt is of the correct size and is placed properly on the pulleys.
- Check the pulley’s condition and alignment: Inspect the pulleys for wear and ensure they are aligned before applying tension to the new belt.
Step 5
Step 6
State THREE main properties that make vesconite an outstanding bearing material.
Answer
- Low co-efficient of friction: Vesconite reduces resistance, leading to increased efficiency in machinery.
- High load bearing strength: It can support heavy loads without deforming.
- Resistance to oils and hydrocarbons: This allows it to be used in various industrial applications without degradation.
