BMG’s heavy industrial couplings

June 2017 Motion Control & Drives

BMG’s heavy industrial Rexnord Falk Steelflex couplings are designed to reduce the shock of high impact loads on equipment by up to 30% and have a unique ‘replace in place’ design, which eliminates the need to remove or reposition hubs, or re-align shafts. The couplings also offer equipment protection against shaft misalignment through the grid, which is quench and tempered and free to rock, pivot and float within the hub teeth. This means misalignment capacity is provided, without producing detrimental bearing side loads created by conventional devices.

When subjected to normal shock or vibratory loads, the grid coupling torsionally deflects to offer enhanced vibration damping and reduce peak torque, thus reducing the wear on connected equipment components. They also act as a shock absorber for rotary motion, relying on the predictable resilience of the steel grid for torsional flexibility.

The Falk grid range, is available in 25 sizes with various bore, speed and torque capacities and there are 11 models available, including high speed, spacer, flywheel, brake and controlled torque. The range has a modular design, which reduces the number of spare parts required in inventory. For example, it is possible to convert a close coupled design coupling to a full spacer by replacing the standard hubs with shaft and spacer hubs. A standard coupling can also be adapted for high speeds by simply changing the horizontal split cover to a vertical split cover. With a few additional components, it is possible to adapt the Falk Steelflex inventory to a variety of applications.

Features of Falk grid couplings include a tapered T-grid profile that fits smoothly into the hub to ensure easy installation and maintenance. High strength alloy steel grids are tempered to spring hardness and precision shot peened for increased fatigue strength to protect equipment against shock and vibratory conditions. Durable, nitrile seals prevent the loss of lubrication and the ingress of water, dust and other materials. Grade 5 cap screws ensure secure fastening of the cover which can be powder coated for resistance to chemicals.

The range offers high torque ratings, low operating costs and extended maintenance periods and the application of Falk Long Term Grease (LTG) means lubrication of couplings is not required again for a period of five years.
