What is the primary function of the component labeled as '3' in the drawing?
What is the primary function of the component labeled as '3' in the drawing?
- To act as a seal preventing contaminants from entering the assembly
- To transmit torque between the shaft and the hub (correct)
- To reduce friction between the shaft and the hub
- To provide lubrication to the assembly
If the shaft diameter in a keyed joint is at its maximum permissible size, how might this affect the selection of the key?
If the shaft diameter in a keyed joint is at its maximum permissible size, how might this affect the selection of the key?
- A smaller key might be chosen to reduce stress on the shaft.
- A key with a different material needs to be selected
- A larger key might be chosen to ensure adequate torque transmission. (correct)
- The key size will remain unaffected by the shaft diameter.
Given the shaft diameter is between 30-38 mm, and the key cross-section is 10x8 mm, how does this proportion influence the joint's performance?
