Keyed Shaft Collars

A keyed is a type of shaft collar that has a keyway machined into its body. The keyway is a tapered slot that engages with a key that is machined into the shaft. This prevents the collar from slipping on the shaft, even under high torque loads.

Keyed shaft collars are commonly used in positive drive applications, such as machine tools, conveyors, and hoists. They are also used in applications where it is important to prevent the shaft from rotating, such as in brake rotors and clutches.

Keyed Shaft Collar

A keyed shaft collar is a mechanical component used to fasten a rotating shaft to a stationary component, such as a bearing or a shaft-hub connection. It is designed to lock onto a shaft with a keyway to prevent slippage or rotation of the shaft collars and any attached components. The keyway is a slot or groove machined into the shaft, which allows the shaft collars to be positioned in a fixed location along the shaft. A matching key is then inserted into the slot or groove, providing a positive mechanical connection between the shaft and the shaft collars.

Keyed shaft collars are commonly used in machinery, equipment, and power transmission systems, where precise positioning and alignment of components are critical. They are easy to install and remove, and they provide a secure and reliable connection between the shaft and the shaft collar, ensuring efficient and safe operation.

Keyed shaft collars are commonly used in positive drive applications to prevent slippage on the shaft. In these applications, other components can be mounted to the shaft collar to allow for the assembly to rotate with the shaft. Keyed two-piece split collars give users the flexibility to assemble the shaft collar in place without the need to remove adjacent components. Keyed can be used as short rigid couplings in space-constrained applications and benefit from increased torque capacity from the keyway.

Keyed shaft collars are available in a variety of sizes and materials. The most common materials are steel, aluminum, and stainless steel. Bore sizes range from 3/8” to 3” and 8mm to 65mm.

▍Features of Keyed Shaft Collars

Keyed shaft collars are a versatile type of shaft collars that can be used in a wide variety of applications. They are ideal for applications where high torque or vibration loads are present or where it is important to ensure that components are aligned properly. Here are some of the key features of keyed shaft collars:

1. High torque capacity: Keyed shaft collars can handle higher torque loads than unkeyed shaft collars. This is because the keyway provides a positive connection between the collar and the shaft.

2. Vibration resistance: Keyed shaft collars are more resistant to vibration than unkeyed shaft collars. This is because the keyway helps to lock the collar in place, preventing it from moving under vibration.

3. Positive alignment: Keyed shaft collars help to ensure that components are aligned properly on a shaft. This is because the keyway prevents the collar from rotating, which can cause misalignment.

4. Easy installation: Keyed shaft collars are easy to install. The key can be inserted into the keyway, and the shaft collar can then be tightened onto the shaft.

▍Applications of Keyed Shaft Collars

Keyed shaft collars are mechanical devices that are used to secure components onto a shaft. They are typically made of metal or plastic and are designed to clamp tightly onto the shaft, preventing the component from slipping. The keyway on the shaft collar allows for precise positioning of the component on the shaft. Here are some common applications of keyed shaft collars:

(1) Power transmission: Keyed shaft collars are commonly used in power transmission systems to secure , pulleys, sprockets, and other components onto a shaft. By using a keyed shaft collar, the component can be accurately positioned on the shaft, which is important for the proper operation of the system.

(2) Robotics: Keyed shaft collars are used in robotics to secure components such as motors, wheels, and gears onto a shaft. They are also used to ensure the precise positioning of these components, which is essential for accurate movement and control.

(3) Industrial machinery: Keyed shaft collars are used in a variety of industrial machinery applications, such as conveyor systems, printing presses, and packaging equipment. They are used to secure components onto a shaft and ensure precise positioning for optimal performance.

(4) Automotive: Keyed shaft collars are used in automotive applications to secure components such as camshafts and crankshafts onto the engine block. They are also used in drive shafts to secure components such as universal joints and yokes onto the shaft.

(5) Medical devices: Keyed shaft collars are used in medical devices such as surgical tools and diagnostic equipment. They are used to secure components onto a shaft and ensure precise positioning for accurate operation.

▍How to Install the Keyed Shaft Collars?

Installing a keyed shaft collar is a fairly straightforward process, but it does require some care and attention to ensure that the shaft collar is properly positioned and tightened. Here are the steps to install a keyed shaft collar:

Clean the shaft: Before installing the keyed shaft collar, make sure that the shaft is clean and free of any debris or contaminants that could interfere with the shaft collar's grip.

Slide the collar onto the shaft: Slide the keyed shaft collar onto the shaft, making sure that the keyway on the shaft collars aligns with the keyway on the shaft. The keyed shaft collar should be positioned close to the component that will be secured onto the shaft.

Position the component: Slide the component onto the shaft, making sure that it is positioned flush against the keyed shaft collar.

Tighten the set screws: Using a hex wrench, tighten the set screws on the shaft collar. It is important to tighten the screws evenly, alternating between screws to ensure that the keyed shaft collar is tightened uniformly. Avoid over-tightening the screws, as this can damage the collar or the shaft.

Check the positioning: After tightening the screws, check the positioning of the component to make sure that it is properly aligned and centered on the shaft. If necessary, make adjustments to the keyed shaft collar or component to achieve the desired position.

Test the assembly: Once the keyed shaft collar and component are properly installed and positioned, test the assembly to make sure that it is secure and operates smoothly.
