Universal joint couplings use a mechanical pivotal action controlled by radial bearings. The Huco-Pol range is injection moulded in acetal with controlled preload to eliminate backlash. This type of coupling has a large offset capacity along with good torsional damping and water resistance. They are also lubrication free. The double jointed versions include a cardan which enables them to also handle radial and angular misalignment. The Huco-Pol range is suitable for use in light duty applications. Their low mass and corrosion resistance make them ideal for applications where conventional steel joints would be under-utilised. They are often used in business machines, food processing plants, laboratory equipment, and electro-medical apparatus among others.
Extensible drive shafts (teleshafts), are useful when the distance between actuator and load varies during operation, or needs to accommodate component variances, or when a quick disconnect facility is needed in the drive line.
Huco teleshafts are in keeping with the light duty capabilities of plastics universal joints and employ precision drawn square brass tubes as the telescoping medium. These can easily be cut by the user to provide an extensible drive shaft with customised dimensions.
