▍Two Piece Keyed Shaft Collar Design Features

Two-piece keyed shaft collars have a number of design features that make them effective at preventing slippage. These features include:

1. Two-piece construction: As the name suggests, two-piece keyed shaft collars consist of two separate pieces that clamp together on the shaft. The two pieces are typically held together with screws or set screws.

2. Keyed design: The keyed shaft collar and the shaft are both machined with a keyway and matching key, which prevents the keyed shaft collar from rotating on the shaft.

3. Material: Two-piece keyed shaft collars are commonly made from materials such as steel, stainless steel, aluminum, or plastic, depending on the application requirements.

4. Bore size: The keyed shaft collar should have a bore size that matches the diameter of the shaft it will be mounted on. The bore diameter may also be tapered to allow for easier installation.

5. Surface finish: The inner surface of the keyed shaft collar that contacts the shaft should have a smooth, flat finish to provide a good surface for locating or stopping other components.

6. Screws or set screws: The two pieces of the keyed shaft collar are typically held together with screws or set screws that are tightened onto the shaft. Set screws have a pointed end that digs into the shaft to provide a secure grip, while screws may require a threaded hole in the shaft.

7. Optional features: Some two-piece keyed shaft collars may include additional features such as tapped holes for mounting additional components, knurled surfaces for improved grip, or special coatings or platings for increased corrosion resistance or wear resistance.

8. Size and weight: Two-piece keyed shaft collars are available in various sizes and weights to suit different applications. The size and weight of the keyed shaft collar should be chosen based on the size and weight of the shaft and the loads that will be applied to it.

9. Tolerance: The keyed shaft collar should be machined to a high degree of precision to ensure a tight fit onto the shaft. The bore diameter and keyway should have tight tolerances to prevent the collar from slipping or moving on the shaft.

▍Two Piece Keyed Shaft Collars Common Applications

Two-piece keyed shaft collars are used in a wide range of applications where a component needs to be located or stopped on a shaft. Some common applications include:

(1) Robotics: Two-piece keyed shaft collars are commonly used in robotics to locate and stop components such as gears, pulleys, and bearings on the shafts of robotic arms or joints.

(2) Manufacturing: Two-piece keyed shaft collars are used in manufacturing equipment to locate and stop components such as sensors, limit switches, and rollers on conveyor belts or assembly lines.

▍Two Piece Keyed Shaft Collar Manufacturers

Shaft collars are machine components that feature a simple design but play an important role in a wide range of industrial applications. They serve three primary functions; holding components in place, locating or positioning components on a shaft, and creating an attachment between the shaft and another component. Designers have a variety of factors to consider, such as style, material, bore size, and shaft geometry, before a selection can be made. It is important to identify the requirements, parameters, and limitations of your system in order to determine the right style for the application.

Despite their simple design, shaft collars play an important role in a wide range of industrial applications. As such, when choosing one for a particular application, it is essential to use the one with the right design and performance characteristics.

▍FAQ

Q1: What is a keyed shaft collar?
A: A keyed shaft collar is a mechanical component designed to provide a secure connection between a shaft and a hub or other component. It features a keyway, which is a slot cut into the collar's bore, and a matching key that fits into the keyway and into a machined slot on the shaft. This arrangement prevents the shaft collar from slipping or rotating on the shaft, ensuring a reliable and accurate connection.

Q2: What are keyed shaft collars used for?
A: Keyed shaft collars are used in a variety of applications where a shaft needs to be securely and accurately connected to a hub or other component. They are often used in power transmission systems, such as motors, gearboxes, and pumps, as well as in mechanical systems that require precise positioning or alignment.

Q3: What materials are keyed shaft collars made from?
A: Keyed shaft collars can be made from a range of materials, including steel, stainless steel, aluminum, brass, and plastic. The choice of material depends on the specific application and the requirements for strength, corrosion resistance, and other properties.

Q4: How do you install a keyed shaft collar?
A: To install a keyed shaft collar, first slide the shaft collar onto the shaft, making sure that the keyway in the shaft collar aligns with the machined slot on the shaft. Then slide the hub or other component onto the shaft, making sure that it also aligns with the keyway and the shaft collar. Finally, tighten the shaft collar's set screws evenly around the circumference of the shaft collar using a torque wrench to the manufacturer's recommended torque value. This will create a secure and accurate connection between the shaft and the hub.

Q5: What are the advantages of using a keyed shaft collar?
A: The main advantage of using a keyed shaft collar is that it provides a secure and accurate connection between the shaft and the hub or other components. This prevents slippage or rotation, ensuring reliable and consistent performance. Keyed shaft collars are also easy to install and remove, making them a convenient solution for many applications.

Q6: What are the disadvantages of using a keyed shaft collar?
A: One potential disadvantage of using a keyed shaft collar is that it requires a precisely machined slot on the shaft, which can be time-consuming and expensive to produce. Additionally, keyed shaft collars may not be suitable for applications where there is a high level of vibration or shock, as the set screws may loosen over time.

Q7: How do you select the right keyed shaft collar for your application?
To select the right keyed shaft collar for your application, you need to consider several factors, including the diameter and length of the shaft, the size and shape of the hub or other component, the torque and load requirements of the application, and the environment in which the system will operate. It is also important to consider the material and finish of the shaft collar, as well as the type and size of the keyway and set screws.
