How to make MN coupling

Gather the necessary materials: The main component of an NM coupling is a non-metallic flexible element, such as a rubber or polyurethane material. You will also need two hubs that match the specific shaft sizes and connection requirements.

Design the coupling: Determine the specifications of the NM coupling based on your application requirements, such as the torque capacity, shaft sizes, and misalignment compensation needed. Sketch or create a 3D model of the coupling design, including the dimensions and features of the flexible element and hubs.

Obtain or fabricate the flexible element: Purchase a pre-made non-metallic flexible element that matches your requirements from a supplier. Alternatively, if you have the capability and resources, you can fabricate the flexible element by molding or cutting it from a suitable non-metallic material.

Prepare the hubs: The hubs are typically made from metal, such as aluminum or stainless steel. Machine or fabricate the hubs to the desired dimensions and features. This may involve turning, milling, or other machining processes to create the necessary bores, keyways, or splines for shaft connection.

Assemble the coupling:

Fit the flexible element onto one of the hubs. Depending on the design, the element may slide onto the hub or require fasteners like screws or clamps for secure attachment.

Align the second hub with the flexible element and insert it into the element while ensuring proper engagement.

Make sure the hubs are properly aligned and centered with each other and the shafts they will be connected to.

Secure the assembly:

Use appropriate fasteners, such as bolts or screws, to securely tighten the hubs together. Ensure that the fasteners do not interfere with the coupling's operation and that they are properly tightened to the recommended torque values.

Test and Verify:

Perform visual and functional checks to ensure the proper alignment and smooth operation of the coupling.

Verify that the coupling meets the desired torque transmission and misalignment compensation requirements by conducting functional tests.

It's important to note that the specific steps and considerations can vary depending on the specific design and materials used for the NM coupling. It is recommended to consult coupling manufacturers, experts, or reference design guidelines for more specific guidance in creating an NM coupling.
