Study Notes
Types of Keys and Fits
- A feather key allows the hub to move along the shaft but prevents the rotation of the shaft.
Spline Fits
- Involute splines use fixed Tabular or Variation fits.
Modified Involute Spline
- The modified involute spline is similar to involute splines but has a pressure angle of 14.5° and is used for permanent fits.
Overload Protection
- Shear pins are used as couplings or in addition to other couplings to prevent injury to the machine or material in case of overload.
Type of Parallel Key
- A Gib head key is a type of parallel key with a rounded end.
