Encoder Couplings with Zero Backlash

Description

Control-Flex couplings from Zero-Max are designed for encoder applications.

Where speed and positioning feedback in a system is critical, Control-Flex couplings help minimize a system’s reaction forces for more precise and repeatable operation and longer life.

Designed with a unique parallel linkage-style flexible disc, Control-Flex provides radial flexibility to reduce reaction forces such as side loads on shaft bearings and seals that can be caused by shaft misalignment. The Control-Flex disc allows parallel, angular and axial shaft misalignments while maintaining constant transmission of torque and angular velocity.

Designed with aluminum clamp-style, zero backlash hubs, the Control-Flex provides a low weight/low inertia solution. Electrically insulating flex discs prevent electrical current passing between the system shafts through the coupling. These discs are made of a special compound selected for its flexible durability and dielectric qualities.

Precision designed, Control-Flex couplings consist of two hubs (to be attached to the system shafts) and a center flex member. This flexible member is affixed to the hubs through quality pins that make separating easy if required. Two versions of the coupling are available: a single-flex disc version for standard torque capacity, and a two-flex disc version for increased torque capacity and torsional stiffness.

Control-Flex couplings are a better option for high precision applications than standard beam style couplings which tend to vibrate and break.  Control-Flex also offers electrical isolation and lower reaction loads than many other coupling options.  Control Flex couplings are ideal for use in packaging, medical device, machine tool, conveying and automated assembly systems that utilize encoder feedback devices.
