  • Keys and Couplings
    Chapter 11 Keys, Couplings and Seals Material taken for Mott, 2003, Machine Elements in Mechanical Design Keys z A key is a machinery component that provides a torque transmitting link between two power-transmitting elements. z The most common types of keys are the square and rectangular parallel keys. With the square being the most common. The rectangular key is most common in either very small or very large shafts. z The key width is nominally ¼ of the shaft diameter. Parallel Keys z The key seats in the shaft and the hub so that exactly ½ of the key bears on the shaft and the other ½ bears on the hub. z The parallel key is installed on the shaft, before mating the hub. The hub is slide over the key to provide the interface. Mott, 2003, Machine Elements in Mechanical Design 1 Key Shaft vs. Shaft Diameter Mott, 2003, Machine Elements in Mechanical Design Dimensions for Fabrication z Keys are usually cut with a end-mill or circular-mill cutters and leave square corners which create stress concentrations. z Radiused keyseats and chamfered keys can reduce stress concentrations. Mott, 2003, Machine Elements in Mechanical Design Key Types z Tapered keys are installed after mating the hub and shaft. The taper extends over the length of the hub. z Pin keys reduce stress concentration, but requires a tight fit. Mott, 2003, Machine Elements in Mechanical Design 2 Woodruff Keys Mott, 2003, Machine Elements in Mechanical Design z Used in light loading applications, where it is desirable to easy assembly and dis-assembly.
