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
During the preventative maintenance of a belt drive system, the following aspects should be checked:
- Wear and Tear on the Belt: Inspect the belt for any signs of damage, fraying, or wear.
- Belt Alignment: Ensure that the belt is properly aligned to prevent undue stress and potential failure.
- Tension Setting: Check the tension of the belt, adjusting as necessary to ensure it is neither too tight nor too loose.
Step 2
State THREE results of a lack of preventative maintenance on a gear drive system.
Answer
The lack of preventative maintenance on a gear drive system can result in:
- Loss of Lubrication: This can lead to increased friction and wear of components.
- Excessive Wear on Components: Neglected maintenance may cause excessive wear, ultimately leading to component failure.
- Noisy Operation: A gear drive system that is not maintained may produce unusual noises due to improper functioning.
Step 3
Name TWO procedures to reduce wear on a chain drive system.
Answer
To reduce wear on a chain drive system, you can:
- Adjust the Chain Tension: Regularly check and adjust the tension of the chain to minimize wear.
- Ensure Adequate Lubrication: Regularly lubricate the chain to reduce friction and wear during operation.
Step 4
Describe the procedure to replace the belt on a belt drive system.
Answer
To replace the belt on a belt drive system, follow these steps:
- Switch Off the Machine: Ensure that the machine is powered down to avoid accidents.
- Release Tension on the Belt: Loosen any tension mechanisms to free the belt.
- Remove the Belt from the Pulleys: Carefully take off the belt from all pulleys.
- Fit the New Belt: Place the new belt onto the pulleys, ensuring correct fitment.
- Check the Pulley's Condition and Alignment: Inspect for any damage and adjust for proper alignment before further tightening.
Step 5
State TWO properties of bakelite.
Answer
Bakelite possesses several properties, but two fundamental ones are:
- Heat Resistant: Bakelite can withstand high temperatures, making it suitable for various applications.
- Electrical Insulator: It is an excellent insulator of both heat and electricity, thereby enhancing its utility in electrical applications.
Step 6
State THREE main properties that make Vesconite an outstanding bearing material.
Answer
Vesconite is recognized as an outstanding bearing material due to:
- Low Coefficient of Friction: It minimizes friction, allowing for smoother operation in bearings.
- High Chemical Resistance: Vesconite resists degradation from oils and hydrocarbons, enhancing longevity.
- Very Versatile: This material can be used in various applications, owing to its durability and performance characteristics.
