Shaft Rigid Coupling-Clamp Screw Coupling-Motor Shaft Coupling

Product Details

What is a rigid coupling?

Rigid coupling is called muff coupling as well. It’s a kind of coupling that used to connect two shafts which are precisely in line. It’s only suitable for shafts in close alignment. Because there is no any flexible component in rigid couplings, a failure will happen if the shafts are not aligned. Rigid couplings serve as components for joining, timing or aligning of shafts rotating at a low speed and torque. It has nice performance when there is zero backlash needed.

Muff coupling types:

There are three types of rigid type couplings. Set screw type, one-piece type and two-piece type. One-piece couplers have superior holding power and maintain alignment. Split, two-piece couplers can be installed and removed without machine disassembly.

Rigid coupling applications:

Rigid couplers are widely used in a variety of industry field as one kind of most budget, convenient and basic coupling. For example, Conveyors/People Movers, Small Wind Power, X-Ray Machines – Medical Indexing, Food Processing, Lawn Mowers, Washing Machines, Exercise Equipment, Automatic Doors, and other high volume applications.

Advantages of muff coupling:

• Extremely rigid connection
• High torque possible
• Wear and maintenance free
• No relative motions between the shafts
• Easy build a shaft alignment in misaligned systems
• Assemblying or disassemblying of the coupling is possible without removing the position of the shafts

Disadvantages of muff couplings:

• The force of misaligned parts by rigid couplers back into alignment may lead to early failures.
• The problems of small amount of shaft misalignment can be eliminated by using flexible coupling.
