Shaft-hub connections Flashcards
Two kinds of keys
- Rectangular
- Woodruff (for light loading, easier (dis-)assembly
Three kinds of splines
- Straight-sided
- Triangular
- Involute
Advantages and drawbacks with splines
+ More uniform load transfer -> can transfer higher torque
+ Involute splines can be accurately machined providing self-centering
+ Allows axial motion under load
- More expensive
Advantages with tapered shaft-hub connections
- Good concentricity
- Contact pressure is not depending on tolerances
Three simple shaft-hub connections that transmit both torque and axial load
- Cylindrical pin
- Taper pin
- Split-turbular pin
What are shear pins?
Cheap torque limiter
Advantage and drawback with using liktjocking as a shaft-hub connection?
+ Low stress concentrations
- High manufacturing cost
Form-based shaft-hub connections
- Keys
- Splines
Friction-based shaft-hub connections
- Press- and shrink fits
- Locking assemblies
Axial shaft-hub connections
- Retaining rings
- Nuts
- Shims
- Shoulders
- Spacers
