Feb 11, 2006 · Most OEM's balance couplings in a vertical balancing machine prior to cutting the keyway. A vertical machine, obviously eliminates the need for a mandrel shaft. Even after the keyway has been cut, most modern balancing instruments will allow "keyway compensation" of a fitment, which is quite accurate and precludes the use of a 1/2 key.
Types of Couplings
Sep 17, 2021 · A shaft coupling is one of the most common machine elements because it is just so important in power transmission systems.Thus, they find use in a variety of applications and service environments. As a result, designers and engineers have designed many variations of couplings for specific service conditions and environments over the years.
Machine Design: LESSON 15 DESIGN OF KEYS
LESSON 15 DESIGN OF KEYS. Key is a machine element which is used to connect the transmission shaft to rotating machine elements like pulley, gear, sprocket or flywheel. Keys provide a positive means of transmitting torque between shaft and hub of the mating element. A slot is machined in the shaft or in the hub or both to accommodate the key is ...
Design of keys
Oct 11, 2012 · Design of keys. 1. A key is a piece of mild steel inserted between the shaft and hub or boss of the pulley to connect these together in order to prevent relative motion between them. It is always inserted parallel to the axis of the shaft. Keys aroused as temporary fastenings and are subjected to consider-able crushing and shearing stresses.

Shaft and Hub Keyway and Key Sizes
bore, a key is commonly inserted into a keyway that is machined in both the bore and shaft. The key is responsible for preventing rotation between the shaft and the bore, and carries a portion of the torque load. Improperly fitted keys and keyways -either too tight or too loose- can result in mechanical failures.

Why Power Transmission Shafts Have Both Keys & Keyways
Key, Keyway, and Keyseat. A key is a piece of metal used to connect a rotating machine element to the shaft. A key prevents a relative rotation between the two parts, and may enable torque transmission to occur. For a key to function properly, both the shaft and rotating elements (gear, pulley and coupling) must have a keyway and a keyseat.
