Keyed Shaft, Dia. 5/8 In, 6 In L, CS

Product Information

Keyed Shafts are designed to transmit torque and rotation between two components. They are usually made of hardened steel, stainless steel, or aluminum and can be used in a variety of applications. Types of Keyed Shafts

They are normally specified for shafts with 0.25 to 1.0-in. Diameter but larger square keys are available for shafts up to 6.5 inches. Diameter. Designers use them when they want as much depth as possible with rectangular keys. 3. Parallel Sunk key Sunk: These keys are set half in the keyway of the shaft and half in the keyway of hub or boss of the pulley. They come in following six types:Based on the scenarios above, the limiting factor is actually the crushing force on the key, and the maximum torque that can be transmitted is reduced by approximately 25 percent (337 Nm based on crushing failure with a key versus 447 Nm for a plain shaft). Again, it’s important to note that the calculations for a keyed shaft do not take into account any service, application, or safety factors. So the recommended maximum torque may be lower than the examples above, depending on other application parameters. Like splined shafts, keyed shafts are available in a variety of materials, lengths, and diameters, and their keys are available in different styles, such as round, saddle, sunk, and tangent.

Parallel, tapered, and Woodruff keyways can be produced on a milling machine. End mills or slotting cutters are used for parallel and tapered keyways, while a Woodruff cutter is used for Woodruff keyways. [10] Keywayed shaft collars are a type of mechanical component used to position and secure components on a shaft when a precise fit and positional alignment are necessary. They have a keyway cut into them that aligns with a key on a shaft to prevent rotation relative to the shaft. These collars are tightened onto a shaft using a screw or clamp to maintain their position. This feature is especially useful in high-torque applications where the collar needs to transmit the rotational force without slipping. They are commonly used in various machinery, such as motors and gearboxes, to hold bearings in place, space components on shafts, or act as mechanical stops. Keywayed shaft collars ensure that the attached components are correctly aligned with the drive elements and do not drift during operation, thereby providing a reliable method for maintaining the assembly of mechanical parts in a variety of industrial and mechanical applications. Installation is much easier when using a keyless connection, as the shaft position does not affect the motor, as the motor can slide in any position. While using a keyed connection, the keyways should be aligned to mount the reducer on the shaft.

Keyed Shafts

The woodruff key is a shaft key made in the form of a segment of a disk and used with shafts not more than 2¹/₂ inches in diameter. An installed wing key cannot run axially. This lets workers subsequently adjust the position of the mounted components along the shaft. Containing teeth or ridges that allow them to mate with other components, splined shafts are primarily used to transfer torque throughout mechanical drive systems while allowing for linear motion, such as those found in vehicles. Normally, they are composed of different metals depending on the localized stresses they are expected to undergo. Their teeth or ridges equally distribute circumferential force to a mated component, facilitating a uniform transfer of torque between the mated pair. This also helps to prolong the lifecycle of the parts. The feather keys are undone to the exact length. There is no need for cutting, measuring, filing, or fitting.
