Zero backlash jaw couplings for machine vision systems

06 July 2012

Ruland offers zero backlash jaw couplings for the demanding requirements of start and stop machine vision systems. The dampening characteristics of Ruland’s jaw couplings reduce settling time and shock loads, making them ideal for these environments. The jaw couplings are a three piece design comprised of two aluminum hubs and an elastomer element called the 'spider'.

Made from an advanced polyurethane material, the spider provides dampening of impulse loads, minimising shock to the motor and other sensitive equipment. Available in three durometers, the spider allows the user to tailor the jaw coupling's performance, such as torsional stiffness, misalignment, and dampening requirements, to their application. For added customisation metric and inch hubs (set screw, clamp style, keyed, or keyless) are interchangeable and can be combined into a single coupling.

Ruland jaw couplings feature a curved profile which press fits onto the spider assuring zero backlash operation. The curved jaw profile concentrates the forces to the center of the spider's limbs, improving the effectiveness of the elastomer material. Raised contact points on the spider limbs help maintain proper spacing between the two hubs, assuring electrical isolation and full angular misalignment capabilities.
