The S54MHCM311012 is a miniature helical coupling with 10 mm and 12 mm bores, made of 7075-T651 aluminum, designed to compensate for angular and lateral misalignment in rotating shaft systems. It has an overall length of 58 mm, a maximum operating speed of 5000 rpm, and a torsional stiffness of 14 N·m/rad. The coupling can accommodate up to 3° of angular offset and a maximum lateral offset specified for its size, with an allowable torque of 200 N·m under a service factor of 2. The part is rated for shock, reversing, and steady load applications according to specified service factors.
Couplings Types
Couplings can be divided into two categories: flexible and rigid. Both types are used to connect two rotating shafts driven by a motor and transmit torque and angular velocity; however, flexible couplings and shafts are designed to accommodate angular misalignment, angular offset, axial movement, and a variety of load conditions. A flexible coupling is pliable due to the twisting and compression of a durable, adaptable material, like neoprene, rubber, or silicone.
Flexibility can also be achieved with thin metal disks, corrugated aluminum bellows (bellows couplings), or even a stainless-steel ball (miniature ball couplings). Some materials can provide vibration reduction, as in our precision flexible antivibration couplings.
Rigid couplings are limited by comparison; rigid couplings are used when shafts are already positioned in precise lateral and angular alignment. Their rigid design inhibits shaft misalignment. They can generally transmit more power than flexible couplings due to their rigidity.
Even the most complicated application challenges can be solved by our skilled engineers, they will identify the best coupling solution for your application. SDP/SI provides a comprehensive range of rigid and flexible couplings. Many of our precision couplings, including the Miniature Bellows Coupling and the Neo-Flex Coupling, have our patented Fairloc® Hub design, which solves phasing, timing, positioning, and frequent removal problems.
