About Universal Joints
Universal joints, or u-joints are flexible mechanical connectors used to transmit rotary motion from one shaft to another shaft that is not in line with the first, or when alignment varies during service. There are two types of universal joints, defined by their number of bending joints. The first, the single joint, has only one bending aspect. As a result, it is capable of operating at up to a 45-degree angle. The second style is the double joint style. By utilizing two bending joints, the double u-joint can operate at angles up to 90 degrees. Additionally, it also accommodate parallel offset between 2 shafts with an operating angle of the central section from 0 to 45 degrees. Universal joints vary based on their material composition, hub type and the applications for which they are designed. Steel is the most common material used, either in stainless form; or alloyed with other metals to handle greater torque and temperature. Plastics and thermoplastics are often used in constructing universal joints, as this lends greater rust and corrosion resistance, as well as electrical and magnetic insulation in applications where this is required.
U-joints are available with two hub styles: solid or bored. There are a number of style variations within the bored types. Solid hub universal joints, are, us the name implies, solid. They have not been machined, and as a result, do not have a hole. This style requires user modification before they can be applied. Bored styles of u-joints generally derive their name from the shape of the hole in their hub, as with round, hex or square styles. Two styles deviate from this convention: splined, with longitudinal grooves inside of the bore, and keyed, which have keyways to prevent rotation of the u-joint on the corresponding shaft.
