Oldham Coupling and its Applications



With industrialization, more and more mechanical engineering parts. The automotive and engineering sector is growing throughout India and the industry is growing to meet the sales needs of some equipment, such as Oldham couplings. In India, there are manufacturers of industrial equipment that can benefit from Oldham coupling.



Such components can accommodate parallel misalignment and serve as mechanical fuses in industrial machines.



Oldham couplings have the main function of promoting light loads. It also stops the transmission of energy in case of overload and reduces the risk of damage to expensive machine components. In addition, the Oldham coupling is a three-piece design consisting of two anodized aluminum hubs and a central torque transmission disc. This is an indispensable element in industrial machinery.



What is Oldham Coupling?

The term Oldham coupling describes the power transmission mechanism. The couplings are designed for applications where there should be no reaction during operation. Today, Oldham couplings are used to replace straight jaw couplings. Oldham Coupling applications are primarily for better performance and efficiency. With respect to the Oldham coupling design, the element consists of three disk-shaped components.



Typically, two discs made of aluminum or stainless steel are connected to both sides of the unit. The third disc, made of various plastics, is between the tongue and the groove design. When in operation, the centers of the discs slide on the tongue perpendicularly to each other. Deliver the torque Oldham couplings are useful for applications with parallel misalignment.

Advantages of Oldham Coupling:-

      1.       Central plastic discs have the potential for electrical insulation.
2.       It acts as a fuse of some kind of machine.
3.       Apply a low reaction force to protect the bearing support.
4.       The drive shaft and the driven shaft rotate at the same speed.
5.       No reaction and torsional stiffness
6.       Electrical insulation function.
7.       Accept large radial misalignment
8.       Economical compared to other couplings with similar performance and characteristics.
9.       Replaceable wear elements are economical.
10.    Low moment of inertia and easy installation in blinds.

     Disadvantages of Oldham Coupling:-


      1.       Accepts relatively small angular misalignments.
2.       Low torque and torsional stiffness
3.       The driven and driven axes do not move at exactly the same speed in a revolution.
4.       The alignment of the angle is incorrect.
5.       When the torque reaches the maximum value, axial reaction loads are applied to the support   bearings.

    
    Applications of Oldham Coupling:- 

      In this era of innovation, new manufacturing technologies are available in the large manufacturing industry. The coupling is the key element of the machine. Oldham couplings were introduced to connect two non-coaxial parallel shafts. The coupling is an element with a good mechanism. It offers the same speed and the same direction of rotation. In addition, the largest applications for Oldham couplings are robotics and servos in addition to printers and copiers.

      For example, a coupling is a component that connects two axes at the ends for the transmission of energy. In the application of the Oldham coupling, it is mainly used to connect two parallel shafts with a very small axial space.

      Couplings are generally used in applications where motion control with zero reaction performance is required.
