Worked Solution & Example Answer:The heavy-duty conveyor wheel shown is driven by a stepper motor - Leaving Cert Engineering - Question e - 2019
Step 1
Describe one method of securely attaching the wheel to the motor shaft.
Answer
One effective method for securing the heavy-duty conveyor wheel to the stepper motor shaft is by using a keyway system. This involves creating a slot (keyway) in both the wheel and the motor shaft, allowing a metal key to be inserted, thus ensuring a tight fit between the two components. Furthermore, a grub screw can be employed to secure the wheel in place once the key is inserted, preventing any relative movement.
The diagram below illustrates this setup:
This method provides stability and ensures efficient torque transfer from the motor to the wheel.
