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.
