Product Description

Custom Precision Clamping Type Flexible Disc Coupling Jaw Coupling Oldham Coupling with CNC Machining

Product Description

Coupling refers to a device that connects 2 shafts or shafts and rotating parts, rotates together during the transmission of motion and power, and does not disengage under normal conditions. Sometimes it is also used

as a safety device to prevent the connected parts from bearing excessive load, which plays the role of overload protection.

Couplings can be divided into rigid couplings and flexible couplings. Rigid couplings do not have buffering property and the ability to compensate the relative displacement of 2 axes. It is required that the 2 axes be strictly aligned. However, such couplings are simple in structure, low in manufacturing cost, convenient in assembly and disassembly, and maintenance, which can ensure that the 2 axes are relatively neutral, have large transmission torque, and are widely used. Commonly used are flange coupling, sleeve coupling and jacket coupling.

Flexible coupling can also be divided into flexible coupling without elastic element and flexible coupling with elastic element. The former type only has the ability to compensate the relative displacement of 2 axes, but cannot cushion and reduce vibration. Common types include slider coupling, gear coupling, universal coupling and chain coupling; The latter type contains elastic elements. In addition to the ability to compensate the relative displacement
of 2 axes, it also has the functions of buffering and vibration reduction.

Coupling performance
1) Mobility. The movability of the coupling refers to the ability to compensate the relative displacement of 2 rotating components. Factors such as manufacturing and installation errors between connected components, temperature changes during operation and deformation under load all put CHINAMFG requirements for mobility. The movable performance compensates or alleviates the additional load between shafts, bearings, couplings and other components caused by the relative displacement between rotating components.
(2) Buffering. For the occasions where the load is often started or the working load changes, the coupling shall be equipped with elastic elements that play the role of cushioning and vibration reduction to protect the prime mover and the working machine from little or no damage.
(3) Safe, reliable, with sufficient strength and service life.
(4) Simple structure, easy to assemble, disassemble and maintain.

How to select the appropriate coupling type
The following items should be considered when selecting the coupling type.
1. The size and nature of the required transmission torque, the requirements for buffering and damping functions, and whether resonance may occur.
2. The relative displacement of the axes of the 2 shafts is caused by manufacturing and assembly errors, shaft load and thermal expansion deformation, and relative movement between components.
3. Permissible overall dimensions and installation methods, and necessary operating space for assembly, adjustment and maintenance. For large couplings, they should be able to be disassembled without axial movement of the shaft.
In addition, the working environment, service life, lubrication, sealing, economy and other conditions should also be considered, and a suitable coupling type should be selected by referring to the characteristics of various couplings.

How to Calculate the Required Size and Specifications for an Oldham Coupling

Calculating the required size and specifications for an Oldham coupling involves considering several key factors. Here’s a step-by-step guide to help you with the calculations:

  1. Identify the Torque Requirements: Determine the maximum torque that the coupling needs to transmit between the two shafts. This can be done by analyzing the torque demands of the application and considering safety factors.
  2. Select the Coupling Material: Based on the operating conditions and the type of machinery, choose a suitable material for the Oldham coupling. Common materials include aluminum, stainless steel, and acetal.
  3. Calculate the Bore Diameter: Measure the diameters of the shafts that the coupling will connect. The bore diameter of the coupling should match the shaft diameters for a proper fit.
  4. Determine the Coupling Size: The coupling’s size is typically specified by its outside diameter and length. Ensure that the selected coupling size fits within the available space in the mechanical system.
  5. Consider Misalignment Compensation: Oldham couplings can accommodate angular misalignment. However, it’s essential to check the coupling’s rated misalignment capability to ensure it meets the application’s requirements.
  6. Check Operating Speed: Verify that the selected coupling can handle the rotational speed (RPM) of the application without exceeding its critical speed.
  7. Factor in Environmental Conditions: If the coupling will be exposed to harsh environmental conditions or corrosive substances, choose a material that can withstand these conditions.

Once you have gathered all the necessary information and made the calculations, you can select the appropriate Oldham coupling that meets the requirements of your specific application. It’s important to consult with coupling manufacturers or engineering experts to ensure the coupling’s compatibility and reliability in your system.
