Double cardan universal joint with needle bearing

Carbon steel universal joints for connecting equipment where there is a misalignment greater than 5 degrees up to an angle of 90 degrees. Fitted with needle bearings lubricated for a lifetime and requiring no maintenance, suitable for applications with speeds of up to 4000 rpm. Smooth and silent operation, suitable applications include connection of conveyers, line shafts and drive shafts.

There are several different types of universal joints, which vary in their design and application.

--Single Cardan joint: This is the most common type of universal joint, and it consists of a single cross-shaped connecting piece that links the two yokes together. This allows the joint to accommodate changes in the relative orientation of the two shafts while transmitting torque and allowing them to rotate.

--Double Cardan joint: This type of universal joint consists of two cross-shaped connecting pieces arranged in series, which link the two yokes together. This allows the joint to accommodate even larger changes in the relative orientation of the two shafts, and it is often used in applications where the shafts may be subjected to more extreme movements.

--Constant velocity joint: This type of universal joint is designed to maintain a constant rotational velocity between the two shafts, even as their relative orientation changes. This is achieved by using a series of small balls or rollers that are arranged specially, allowing the joint to accommodate changes in orientation while maintaining a constant velocity.

--Hooke’s joint: This type of universal joint uses a series of curved arms, or levers, to link the two yokes together. This allows the joint to accommodate changes in orientation while transmitting torque and allowing the shafts to rotate.

--Cross and bearing joint: This type of universal joint uses a cross-shaped connecting piece and a series of bearings to link the two yokes together. This allows the joint to accommodate changes in orientation while transmitting torque and allowing the shafts to rotate.

Product Description

When a single universal joint is insufficient to compensate for all misalignment, a combination of joints can offer a suitable solution.

The HKAA double universal joint (double Cardan joint) provides the same reliability and service life as the single universal joint with a maximum combined working angle of 90°. Double universal joints provide accurate positioning and flexibility under higher operating angles.

Double U Joints take lower loads than single joints; this is a recommendation by the joint standard due to the additional bending moments and forces that are applied to the center section and which are transferred to the joints as additional loads.

Advantages of Universal Joints

--Flexibility: Universal joints can accommodate changes in the relative orientation of the two coupled shafts, allowing them to move and rotate freely in different directions. This makes them ideal for applications where the shafts may be subject to large and varying forces or need to move and rotate in different directions.

--Versatility: Universal joints can transmit torque and allow the shafts to rotate, making them useful for a wide range of applications where power transmission or rotation is needed.

--Compactness: Universal joints are relatively small and compact, which makes them easy to incorporate into a wide range of mechanical systems.

--Durability: Universal joints are typically designed to be robust and durable, with high-quality bearings and other components that can withstand large forces and long-term use.

--Cost-effectiveness: Universal joints are generally less expensive than other types of couplings, which makes them an economical choice for many applications.
