Where is Cardan shaft used?

Cardan Shafts and Universal Joints | TYMA CZ

Cardan shafts, also known as driveshafts, have a long history that began in the automotive sector. Introduced in the mid-19th century, the first recorded use of the Cardan shaft was in Stover's patent for planing and matching machines, which replaced previous belt drives with a more efficient Cardan shaft system. Similarly, the technology saw application in a patent for the Watkins and Bryson horse-drawn lawn mower, highlighting its evolving utility in machinery.

In further developments, the term 'Cardan shaft' referred to various applications, including a locomotive's driving mechanism and a bicycle's crank-to-axle connection. Notably, Bukey characterized it as a system conveying power from wheels to a machine using a universal joint. This innovation transcended mere vehicle mechanics into broader industrial applications, including marine propulsion systems. The historical importance of the Cardan shaft is underscored by its early adoption in the first gasoline-powered car by Autocar, now a prized exhibit in the Smithsonian Institution’s collection.

What is an Industrial Cardan Shaft?

The Cardan shaft comprises a shaft tube, a telescopic sleeve, and dual cross joints, designed to adapt automatically to variations in distance between the transmission and the driving axle. This mechanism allows for angle adjustments between the output shaft and input shaft, ensuring consistent angular velocity transmission. In heavy-duty applications, Cardan shafts also serve critical roles in vibration damping and enhancing the shaft system's dynamic performance.

Typically, an industrial Cardan shaft connects two halves to the primary and driven shafts respectively, making it indispensable for the functionality of numerous power machines.

How can the Cardan Shaft help during the machine's running?

The Cardan Shaft significantly enhances power and torque transmission in operational machinery while providing cushioning and vibration damping that improves dynamic performance. Traditional drive systems like belts or chains, while functional, often deliver lower torque, shorter operating time, and require frequent maintenance. In contrast, the adoption of Cardan Shafts promotes efficiency, supporting power transmission across diverse planes and angles, up to 45 degrees.

Furthermore, the one-piece forkhead design of the Cardan Shaft makes it convenient to transport, and the transmission efficiency can reach an impressive 98-99.8%. This positions Cardan Shafts as essential components in energy conservation. Maintenance of the Cardan Shaft is straightforward, generally requiring only regular lubrication of its cross u-joint.

Types of Cardan Shafts

While Cardan Shafts are prevalent in the automotive sector, their use has expanded significantly in mechanical engineering as technology has advanced. Typically categorized by structure, Cardan Shafts can be divided into several types: light, long-life, medium, heavy, hollow penetration, and ultra-short Cardan Shafts.

Light Cardan Shafts, with high mounting angles and low inertia, are often employed in paper-making machinery and general machinery, with torque capacities ranging widely. Long series Cardan Shafts are designed for greater bearing life and torsional rigidity, making them suitable for extensive machinery applications, while medium-sized variants serve versatile needs across industries.

Heavy-duty models are crafted from specialized materials with enhanced durability, appropriate for extreme conditions found in industries such as metalworking. Hollow penetration Cardan Shafts cater to specific needs in bar and H-beam mills, reflecting varying installation constraints. Lastly, ultra-short Cardan Shafts fit compact applications, commonly utilized in locomotives and related machinery.

Do you want to replace your old Cardan Shaft or Need a New One?

With diverse structures and models available, selecting the appropriate Cardan Shaft necessitates a comprehensive understanding of its types and specifications. While maintenance demands are minimal, the cross u-joint will typically need service within a year. Regular lubrication is crucial, as is adhering to the specified torque limitations to ensure longevity.

As several manufacturers offer Cardan Shafts at varying price points, understanding production processes helps gauge quality. Choosing reputable manufacturers specializing in quenching processes ensures components like flanges and shaft forks are optimally treated for durability.

Replacement should be viewed not as a cost but a strategy to maintain efficient operation. Engaging with manufacturers six months prior for preparation and confirmation promotes readiness for any contingencies.
