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

Product Information

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. a b c d Keys and Keyways (PDF), archived from the original (PDF) on 2011-06-14 , retrieved 2010-03-19.

Splines: Splines are ridges or teeth on a drive shaft that mesh with grooves in a mating piece and transfer torque to it, maintaining the angular correspondence between them. A gear mounted on a shaft might use a male spline on the shaft that matches the female spline on the gear. The splines or serrations are milled or hobbed to size and shape and then heat treated. a b Cutting Keyways - Broaching, Keyseating, Wire-Cut EDM, Shaping, & Milling , retrieved 2014-12-03. 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 theKeywayed 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. Shaping or slotting is largely used for cutting keyways that do not extend through the full length of the part. Like keyseating, shaping uses a single-point cutting tool for cutting, however, shapers are not guided through the cut on a fixed post. As such, shaper cuts are generally more susceptible to deflection than keyseater cuts. [9] Milling [ edit ] 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: A Scotch key or Dutch key features a circular keyway hole (instead of rectangular), produced by drilling axially into the assembled hub and shaft, with a metal dowel pin serving as the key. If the hole and key are tapered, the key is referred to as a Dutch pin, which is driven in and optionally finished by cutting or grinding flush with the end of the shaft. If a straight Dutch keyway hole is optionally tapped with a thread, then an ordinary screw serves as the threaded Dutch key.

Power transmission between two rotating components requires a secure connection between the shaft of the driving component, and the hub of the mating part. One way to ensure torque transmission without slipping is by using a keyed connection. For most automation applications (motors, gearboxes, pulleys, etc.), a parallel key, also known as a straight key, with a square cross-section is used.

The deeper either slot, the forward key enters axially. 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.One of the earliest forms of keyseating was done by chiseling. The keyway is roughed out using a chisel and then filed to size; the key is tried frequently to avoid over filing. This technique is long, tedious, and rarely used anymore. [11] Keyed joints [ edit ]
