Ruland Manufacturing continues to expand its motion control coupling product line by introducing bellows couplings with increased misalignment capabilities. These new bellows couplings complement Ruland’s existing high-stiffness line by offering equivalent torque with greater misalignment flexibility.
An independent cheese packager
in central Wisconsin packages millions of pounds of cheese every year. Whether shredded, sliced, crumbled or waxed, each package is designed specifically for a customer’s unique needs. As a “toll processor,” production line speed is critical to productivity as well as profitability.
Bellows couplings first began to be
widely used by machine tool builders
in the mid-to-late 20th century. With the
advent of CNC technology, machine
engineers started looking to improve
upon some of the negative influences
traditional power transmission couplings
can have on a precision rotary /
linear motion system.
A new solution has been developed around
the use of microprocessor-controlled
prostheses. Just like natural limbs, these
can react automatically, adapting to the
current situation.
For many years bellows couplings have been near the top of the list of flexible coupling choices for high-performance motion systems. Their high
torsional stiffness, low moment of inertia and minimal restoring forces under misalignment make them a preferred choice for maintaining tight control over the load.
