These advancements contribute to the overall efficiency, reliability, and performance of cardan couplings, making them more suitable for a wide range of applications.
Handling High Torque and Axial Displacement with Cardan Couplings
Cardan couplings, also known as universal joints or u-joints, are designed to transmit torque between two shafts that are not in a straight line. They are versatile components commonly used in various applications, including those requiring high torque and axial displacement.
Handling High Torque: Cardan couplings are capable of handling high levels of torque transmission due to their robust design and construction. The design allows for torque to be transmitted through a series of interconnected components, including the cross-shaped yokes and the bearing assemblies. The use of high-strength materials and precision manufacturing techniques contributes to the coupling’s ability to transmit torque efficiently.
Handling Axial Displacement: While cardan couplings are primarily designed for accommodating angular misalignment, they can also handle a certain degree of axial displacement. Axial displacement refers to the movement of the connected shafts along their axis. However, the axial displacement capacity of a cardan coupling is limited compared to its ability to handle angular misalignment.
It’s important to note that excessive torque or axial displacement beyond the coupling’s design limits can lead to premature wear, increased vibrations, and reduced performance. Manufacturers provide specifications and guidelines for the maximum torque and axial displacement that a specific cardan coupling can handle. Engineers and designers should adhere to these specifications to ensure optimal performance and longevity of the coupling in their applications.
How do you properly install and maintain a cardan coupling in machinery?
Proper installation and maintenance of a cardan coupling are crucial to ensure its reliable performance and longevity:
- Installation:
- Align the shafts properly before connecting the coupling to minimize initial misalignment.
- Ensure that the universal joints are in phase, meaning their yokes are in the same orientation to prevent uneven torque transmission.
- Follow the manufacturer’s instructions for torque specifications while tightening bolts and fasteners to prevent overloading or loosening during operation.
- Make sure the coupling is properly centered and balanced to avoid vibrations.
- Check for any obstructions or interference that might affect the movement of the coupling.
- Maintenance:
- Regularly inspect the coupling for signs of wear, such as cracks, corrosion, or damaged components.
- Monitor the alignment of the shafts to detect any misalignment that might occur over time.
- Lubricate the universal joints and bearings as recommended by the manufacturer to reduce friction and wear.
- Replace worn or damaged components promptly to prevent further deterioration and potential coupling failure.
- Perform vibration analysis and balancing to ensure the coupling operates smoothly and doesn’t contribute to excessive vibrations in the machinery.
- Regularly check for any signs of overheating, which might indicate inadequate lubrication or other issues.
- Keep the coupling area clean from debris, dirt, and contaminants that could affect its performance.
By following proper installation procedures and conducting regular maintenance checks, you can maximize the efficiency and reliability of a cardan coupling in machinery.

Lead Screws and Clamp Style Collars
If you have a lead screw, you’re probably interested in learning about the Acme thread on this type of shaft. You might also be interested in finding out about the Clamp style collars and Ball screw nut. But before you buy a new screw, make sure you understand what the terminology means. Here are some examples of screw shafts:
Acme thread
The standard ACME thread on a screw shaft is made of a metal that is resistant to corrosion and wear. It is used in a variety of applications. An Acme thread is available in a variety of sizes and styles. General purpose Acme threads are not designed to handle external radial loads and are supported by a shaft bearing and linear guide. Their design is intended to minimize the risk of flank wedging, which can cause friction forces and wear. The Centralizing Acme thread standard caters to applications without radial support and allows the thread to come into contact before its flanks are exposed to radial loads.
The ACME thread was first developed in 1894 for machine tools. While the acme lead screw is still the most popular screw in the US, European machines use the Trapezoidal Thread (Metric Acme). The acme thread is a stronger and more resilient alternative to square threads. It is also easier to cut than square threads and can be cut by using a single-point threading die.
Similarly to the internal threads, the metric versions of Acme are similar to their American counterparts. The only difference is that the metric threads are generally wider and are used more frequently in industrial settings. However, the metric-based screw threads are more common than their American counterparts worldwide. In addition, the Acme thread on screw shafts is used most often on external gears. But there is still a small minority of screw shafts that are made with a metric thread.
ACME screws provide a variety of advantages to users, including self-lubrication and reduced wear and tear. They are also ideal for vertical applications, where a reduced frictional force is required. In addition, ACME screws are highly resistant to back-drive and minimize the risk of backlash. Furthermore, they can be easily checked with readily available thread gauges. So, if you’re looking for a quality ACME screw for your next industrial project, look no further than ACME.
Lead screw coatings
The properties of lead screw materials affect their efficiency. These materials have high anti-corrosion, thermal resistance, and self-lubrication properties, which eliminates the need for lubrication. These coating materials include polytetrafluoroethylene (PFE), polyether ether ketone (PEK), and Vespel. Other desirable properties include high tensile strength, corrosion resistance, and rigidity.
The most common materials for lead screws are carbon steel, stainless steel, and aluminum. Lead screw coatings can be PTFE-based to withstand harsh environments and remove oil and grease. In addition to preventing corrosion, lead screw coatings improve the life of polymer parts. Lead screw assembly manufacturers offer a variety of customization options for their lead screw, including custom-molded nuts, thread forms, and nut bodies.
Lead screws are typically measured in rpm, or revolutions per minute. The PV curve represents the inverse relationship between contact surface pressure and sliding velocity. This value is affected by the material used in the construction of the screw, lubrication conditions, and end fixity. The critical speed of lead screws is determined by their length and minor diameter. End fixity refers to the support for the screw and affects its rigidity and critical speed.
The primary purpose of lead screws is to enable smooth movement. To achieve this, lead screws are usually preloaded with axial load, enabling consistent contact between a screw’s filets and nuts. Lead screws are often used in linear motion control systems and feature a large area of sliding contact between male and female threads. Lead screws can be manually operated or mortised and are available in a variety of sizes and materials. The materials used for lead screws include stainless steel and bronze, which are often protected by a PTFE type coating.
These screws are made of various materials, including stainless steel, bronze, and various plastics. They are also made to meet specific requirements for environmental conditions. In addition to lead screws, they can be made of stainless steel, aluminum, and carbon steel. Surface coatings can improve the screw’s corrosion resistance, while making it more wear resistant in tough environments. A screw that is coated with PTFE will maintain its anti-corrosion properties even in tough environments.
Clamp style collars
The screw shaft clamp style collar is a basic machine component, which is attached to the shaft via multiple screws. These collars act as mechanical stops, load bearing faces, or load transfer points. Their simple design makes them easy to install. This article will discuss the pros and cons of this style of collar. Let’s look at what you need to know before choosing a screw shaft clamp style collar. Here are some things to keep in mind.
Clamp-style shaft collars are a versatile mounting option for shafts. They have a recessed screw that fully engages the thread for secure locking. Screw shaft clamp collars come in different styles and can be used in both drive and power transmission applications. Listed below are the main differences between these two styles of collars. They are compatible with all types of shafts and are able to handle axial loads of up to 5500 pounds.
Clamp-style shaft collars are designed to prevent the screw from accidentally damaging the shaft when tightened. They can be tightened with a set screw to counteract the initial clamping force and prevent the shaft from coming loose. However, when tightening the screw, you should use a torque wrench. Using a set screw to tighten a screw shaft collar can cause it to warp and reduce the surface area that contacts the shaft.
Another key advantage to Clamp-style shaft collars is that they are easy to install. Clamp-style collars are available in one-piece and two-piece designs. These collars lock around the shaft and are easy to remove and install. They are ideal for virtually any shaft and can be installed without removing any components. This type of collar is also recommended for those who work on machines with sensitive components. However, be aware that the higher the OD, the more difficult it is to install and remove the collar.
Screw shaft clamp style collars are usually one-piece. A two-piece collar is easier to install than a one-piece one. The two-piece collars provide a more effective clamping force, as they use the full seating torque. Two-piece collars have the added benefit of being easy to install because they require no tools to install. You can disassemble one-piece collars before installing a two-piece collar.
Ball screw nut
The proper installation of a ball screw nut requires that the nut be installed on the center of the screw shaft. The return tubes of the ball nut must be oriented upward so that the ball nut will not overtravel. The adjusting nut must be tightened against a spacer or spring washer, then the nut is placed on the screw shaft. The nut should be rotated several times in both directions to ensure that it is centered.
Ball screw nuts are typically manufactured with a wide range of preloads. Large preloads are used to increase the rigidity of a ball screw assembly and prevent backlash, the lost motion caused by a clearance between the ball and nut. Using a large amount of preload can lead to excessive heat generation. The most common preload for ball screw nuts is 1 to 3%. This is usually more than enough to prevent backlash, but a higher preload will increase torque requirements.
The diameter of a ball screw is measured from its center, called the ball circle diameter. This diameter represents the distance a ball will travel during one rotation of the screw shaft. A smaller diameter means that there are fewer balls to carry the load. Larger leads mean longer travels per revolution and higher speeds. However, this type of screw cannot carry a greater load capacity. Increasing the length of the ball nut is not practical, due to manufacturing constraints.
The most important component of a ball screw is a ball bearing. This prevents excessive friction between the ball and the nut, which is common in lead-screw and nut combinations. Some ball screws feature preloaded balls, which avoid “wiggle” between the nut and the ball. This is particularly desirable in applications with rapidly changing loads. When this is not possible, the ball screw will experience significant backlash.
A ball screw nut can be either single or multiple circuits. Single or multiple-circuit ball nuts can be configured with one or two independent closed paths. Multi-circuit ball nuts have two or more circuits, making them more suitable for heavier loads. Depending on the application, a ball screw nut can be used for small clearance assemblies and compact sizes. In some cases, end caps and deflectors may be used to feed the balls back to their original position.
