Woodruff Key Stock

Woodruff key stocks are rounded machine keys. They have a half-moon shape for use on a mating half-mooned keyway that is milled near the end of the shaft. These woodruff keys, also known as half?moon keys, lock the mated gear / hub to the shaft by using their protruding flat face, allowing a tight fit. This prevents the independent movement of the attached hubs / gears / components from the rotating shaft / spindle and ensures better torque transfer. Raptor Supplies offers woodruff key stocks from brands like Gorlitz, Grainger & Vulcan Hart. They also protect expensive parts / components by acting as a fail-safe and shearing under excess loads to absorb / disperse the turning shaft's energy.

Features

  • Woodruff key stocks are ideal for connecting gears & components to driveshafts in machine tools and engines.
  • Their crescent profile allows them to sit deep inside the shaft for decreasing their chances of laterally rolling out of the shaft groove.
  • They do not allow axial movement between the shaft & the connected component.
  • Grainger woodruff key stocks have C1035 steel construction for durability and handling strain & stress.

Frequently Asked Questions

What are the advantages of woodruff keys?

  • Woodruff key stocks may be used over key slots of tapered shafts as they can get aligned via slight rotation in their seat.
  • The extra key depth in the shaft prevent slipping over the shafts.
  • Since they are not fitted at the shaft end, stress concentration is reduced at the shaft end.
  • These keys are ideal for assemblies that are rotating at high speeds.

How to install a woodruff key?

  • Press the key into the semi-circular key slot (milled into the shaft). Tap the flat, protruding key face using a hammer / mallet to seat the key firmly.
  • Allign the flat surface parallel to the shaft. The key face may extend above the shaft's surface to lock the mated component in place.
  • During installation, if the key slips out of the grooved key slot, then either the size is too small or the key is not press-fitted properly.
