💡 What is a spur gear and how does it transfer torque between parallel shafts?
A spur gear uses straight teeth to transfer rotational power between parallel shafts when meshing with a gear of identical DP and PA.
- Torque is transferred through gear teeth engagement
- Works with matched diametral pitch and pressure angle for smooth motion
- Cast iron construction offers strength and wear resistance
