Types of Coupling
The oldham coupling is a form of flexible coupling designed for applications that must be free from backlash. They are also increasingly being used as a replacement for straight jaw couplings. The oldham coupling consists of three discs.
3.4 Miscellaneous Couplings This group of couplings incorporate design features which are frequently unique, approximations or combinations of universal, Oldham and flexible shaft couplings. Two widely used couplings in this category are the Jaw and Sleeve types, both of which are available in the Product Section of our catalog.
If we couple the system these tension and compression forces transfer through the coupling beam as a shear force for which the beam is designed. A stiffness of the coupling beam plays an important role in the adding the stiffness of the system.
What are bellows couplings? One form of flexible coupling with very low and near zero-backlash is the bellows coupling. The key benefits of bellows couplings include misalignment compensation and precise transmission of velocity, angular positioning and torque.
Chain couplings are devices that are used in a number of different applications, ranging from heavy equipment to the creation of jewelry. A basic definition for a chain coupling is a device that is utilized as a means of connecting one or more sections or lengths of chain, or connecting a length of chain to an object.
This diaphragm coupling originally developed for helicopter drive shafts has been redesigned for general industrial purposes. The diaphragm part employs a special profile processing (characterized by high torsional rigidity, flexible against bending/compression) to achieve high torque transmission.
Disc Couplings The Rexnord Disc Coupling portfolio provides customers with a range of solutions to choose from for any specific application, including low or high speeds, torques or misalignments. With disc coupling product lines Thomas, Addax, Euroflex and Moduflex, we ensure an optimized solution for your specific need.
Flexible couplings are designed to accommodate misalignment between shafts and various types of load conditions. Many styles and types of couplings are available. For successful coupling selection, application conditions must be clearly understood.
The Falk Lifelign GC05 Gear Couplings are designed for compactness. With two hubs and one sleeve, the simplicity of the continuous sleeve GC05 coupling allows for easy adaptation to a wide range of applications. The compact, low rotating mass and lower initial cost than flanged options is a very attractive solution for many applications.
Grid couplings are a versatile, proven technology with interchangeable components readily available from several major coupling manufacturers (including Lovejoy). Grid couplings have a high power density (transmit a high amount of torque relative to their size), and are relatively straightforward and simple to install.
Jaw coupling torque is transmitted through the elastomer lobes in compression. The elastomer of the spider can be made in different materials and hardness, which allows the user to customize the coupling to best serve their application. Considerations for elastomer selection include ability to dampen vibration, ability to handle misalignment, operational temperature range, speed of equipment, and chemical conditions.
