Product Information

The key in the radius end component keyway of the main funnel simplifies assembly. And wing keys are easily inserted into the shaft. The radius helps align the key in the shaft slot. 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. Occasionally, the keys are formed inseparably with the shaft that fits into the keyway fitted to the hub. Such shafts are known as splendid shafts. These shafts usually have four, six, ten, or sixteen partitions. Peeled shafts are relatively stronger than single keyway shafts.

Parallel keys are commonly used in mechanical and automotive engineering because of their inefficiency, availability, and ease of installation. Tangent keys are used in heavy-duty equipment. These keys are actually a pair. These pair of keys are placed right angles to each other and tangent to the surface of the shaft, each key will withstand the torsion in one direction only. Gib keys, or gib head keys, are tapered and notched machine keys that are used on power transmission keyed shafts to hold pulleys and gears tightly on the shaft. The head of the key serves as a concussion point for hammering without damage to the shaft of the key. 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 theKeyed 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 The depth of the slot in both the shaft and the component controls the axial position, but cannot be predetermined. The deeper either slot, the forward key enters axially. Install them in the shaft to transmit gear from the shaft to the shaft and other components. Machine keys are often the same material and are harder or tougher than the shafts or other components with which they are used. To use a key as part of a sacrifice, choose a soft key that will turn off when exposed to excessive force, so as not to damage expensive equipment. 2. Square Sunk key

Tangent keys are used in high-torque heavy-duty applications. What would have been the side of each keyway forms heels against which the key sits, and transfers force compressively. This latter point means that for reversible motion of the shaft, another key along a tangent outwards in the opposing direction is needed. Typically this will be offset by 90° or 180° on the shaft. The key may be wedge, rectangular, or square shaped, but particularly rectangular double-taper keys are used. 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. Broaching is primarily used to cut square cornered internal keyways. The specific broach, bushing and guide are used for each given keyway cross-section, which makes this process more expensive than most of the alternatives. However, it can produce the most accurate keyway out of all the processes. There are three main steps in broaching a keyway: First, the workpiece is set on the arbor press and the bushing is placed in the opening of the workpiece. Next, the broach is inserted and pushed through, cutting the keyway. Finally, shims are placed between the bushing and the broach to achieve the correct depth necessary for the key. [6] Keyseater [ edit ] A keyseater and a sample of various shapes that can be cut Modern keyseating machine 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 keyIt 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 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 One part of the Shaft key fits into a precut slot in the shaft known as a key seat and the other part fits into a slot in the hub called a keyway. The whole system is called a keyed joint. A keyed joint may allow relative axial movement between the parts.

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 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] Bhandari, V. B.

Keyed Shafts can be found in industries ranging from automotive manufacturing to aerospace engineering. Professionals use them in everything from electric motors and transmissions to pumps and compressors.

A saddle key is a key for securing a member to a machine shaft that fits into a keyway in the secured member and is concave to grip the shaft by friction compared to a flat key, or 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: 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. 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. Improperly machined keyways that had cutter deflection or drifting occur, may not be strong enough for the required application.

Keyseaters, also known as keyseating machines and keyway cutters, are specialized machines designed to cut keyways. They are very similar to vertical shapers; the difference is that the cutting tool on a keyseater enters the workpiece from the bottom and cuts on the down-stroke, while the tool on a shaper enters the workpiece from the top and cuts downward. Another difference is a keyseater has a guiding system above the workpiece to minimize deflection, which results in a closer tolerance cut. The process starts by clamping the workpiece to the table with a fixture or vise. The workpiece is properly located and then the reciprocating arm is started. Some models have a stationary table so the cutter is fed horizontally into the workpiece, while others have a movable table that feeds the workpiece into a fixed cutter. These machines can cut other straight sided features other than keyways (see the picture). They can also produce blind slots, which are slots that do not extend through the whole workpiece. [7] [8] Wire-cut electrical-discharge machining (EDM) [ edit ] There are two different types of connections between a shaft and a hub. This article will discuss the differences between the keyed shaft and keyless connections and their advantages/disadvantages. 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. Leonard, William Samuel (1919) [1905].

Compared to sunk keys, saddle keys are not sunk into the shaft and hub instead they are only sunk into the hub. They either sit on a flat or the circumference of the shaft. Power transmission is achieved through friction between the shaft and the key. The saddle keys are of the following two types:
