Description

The feather keys are undone to the exact length. There is no need for cutting, measuring, filing, or fitting.

The round keys are circular in section and fit partially in the shaft and partially drilled holes in the hub. They have the advantage that after assembling the mating parts their key drills can be performed again. Round keys are generally considered best suited for low-power drives. Splines keys Spoiled shafts are used when the force to be transmitted is proportional to the size of the shaft as in automobile transmission and sliding gear transmission. By using split shafts, we obtain axial movement as well as a positive drive. Material Selection for Shaft key Round: These are used mostly for low power drives. They are circular and fit into holes drilled partly in the shaft and partly in the hub. Round keys are usually considered to be most appropriate for low power drives. These are not as popular as the rounded edge is much more prone to shearing than a square edge. They are mostly used to transmit only unidirectional torques subjected to lighter initial loads, or in applications that require periodic clearance or sliding of the hub, as the drive component may become free due to multi-axial torches, While the major loosens and gets trapped inside. Machine, the reason for failure. 4. Gib head keya b c d Keys and Keyways (PDF), archived from the original (PDF) on 2011-06-14 , retrieved 2010-03-19. Feather keys are fully contained. It does not set-up to hold the key in position and the wing keys cannot move out of the assembly.

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. Bhandari, V. B. (2007), Design of machine elements (2nded.), Tata McGraw-Hill, p.340, ISBN 978-0-07-061141-2. A Shaft key is a piece of metal used to connect a rotating machine element to the shaft. A shaft key prevents a relative rotation between the two parts, and may enable torque transmission to occur. For a shaft key to function properly, both the shaft and rotating elements ( gear, pulley, and coupling) must have a keyway and a keyseat. ball bearings, roller bearings, thrust bearings, ceramic and ceramic hybrid bearings, stainless steel bearings, miniature bearings, linear bearings, shafting, corrosion resistant bearings - see the full listing in the a b Cutting Keyways - Broaching, Keyseating, Wire-Cut EDM, Shaping, & Milling , retrieved 2014-12-03.

The second possible mode of failure, also caused by forces exerted on the key by the shaft and hub, is based on compressive forces, which can induce permanent deformation and crush the key. In this case, the maximum torque that can be transmitted is based on the height, rather than the width, of the key. 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.

The shaft key material must be chosen based on the operating environment. A designer must very carefully consider the loads that will be applied to the material and what kind of environment will be in the service. Carbon steel is used more broadly than any other material. Carbon steel provides very good strength through heat treatment.

Splined Shafts

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. Tangent: These keys are used in large, heavy-duty shafts. Pairs of these keys are set in right angles to withstand twisting from applied torque, in just one direction. Feather Keys are a rectangular key connecting the keyways of a shaft and a hub of a gear, pulley, etc., fastened in one keyway and free to slide in the other so that the hub can drive or be driven by the shaft at various positions along with it. It can be replaced to provide a high degree of strength or wear resistance. Austenitic (300 Series) stainless steel shaft key material should be used where the material will be exposed to a highly corrosive environment. High-strength materials are required and martensitic stainless-steel shaft key material should be used when exposed to mildly corrosive environments. Benefits and limitations of keyed joints Feather keys may not fall out of the shaft and may damage nearby machinery. (Loose key in the working machinery is a major cause of damage and injury.)

A hollow saddle key is a taper key that fits into a keyway in the hub and is shaped under the key to fit the curved surface of the shaft. Since hollow saddle keys are gripped by friction, they are suitable for light loads. It is commonly used as a temporary fastener in fixing and installing eccentrics, cams, etc. Tangent key 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 When the connection rotates, the shaft and hub (mating part) exert opposing forces on the key, attempting to shear the key. The maximum torque that can be transmitted before exceeding the yield strength of the key is calculated as:

 

Like other types of shafts, they are available in a collection of styles, including ball splines, crowned splines, helical splines, serrations, and parallel splines. 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] Keyed Shaft, what is a keyed motor shaft. In mechanical engineering, a key is a machine element used to connect a rotating machine element to a shaft. A machine runs by the power supplied to it by a prime mover such as motor, engine, etc. The power is then transmitted from the prime mover to the machine through a coupler which couples the shafts of the prime mover and the machine.
