Durst is Doing Something About Torsional Vibration

The Durst division of Regal Beloit Corporation today announced a working relationship with Torsion Control Products, Inc. Torsion Control Products will review all Durst applications using the new Durst PD pump drive gearboxes for torsional vibration. If it is determined a coupling is required, Durst and Torsion Control Products will specify a Torsion Control Products spring coupling to eliminate the torsional vibration issues. Durst, the most trusted source for hydraulic pump drives used in mobile off-highway applications, and Torsion Control Products, a leading producer of spring couplings, are offering customers the ideal torsional coupling for Durst pump drive applications involving Tier I through Tier IV diesel engines.

“Because uncontrolled torsional vibration emanating from modern diesel engines can cause premature fatigue and failure in crankshaft and driveline components, Durst and Torsion Control Products are working together to solve torsional vibration problems before they have a chance to occur,” said Bob Brandemuehl, Engineering Manager at Durst. “The costs incurred due to torsional vibration damage can be substantial. Now OEMs and distributors can select a simple, economical package to serve their customers that will increase drive system durability and help prevent catastrophic failures.”

Torsion Control Products provides tuned spring couplings to address torsional vibration in all types of applications. This includes agricultural, construction, industrial, marine, mining and gen-set applications. To ensure the integrity of the power transmission system, Durst relies on a highly accurate torsional vibration analysis performed by Torsion Control Products prior to the installation of a Durst pump drive. Torsion Control Products’ vibration analysis assesses the impact of torsional vibration occurring in the driveline. Durst and Torsion Control Products’ engineers work together to evaluate the specific application to determine if the system will benefit from a properly tuned torsional coupling. If it is determined a torsional coupling will benefit the application, a Torsion Control Products-designed spring coupling tuned for that application will be provided with the gearbox. This will eliminate problems caused by random selection of couplings or drive plates that can impact the service life of driven equipment. Evaluating the need for and utilizing the proper coupling or drive plate reduces downtime and repair costs, leading to longer life of the driveline system.

“Over the past 25 years, Torsion Control Products has worked with original equipment manufacturers to address resonance and torsional vibration issues independently,” commented Mike Mackool of Torsion Control Products. “Durst providing tuned packages for their customers makes sense, avoiding torsional vibration problems from the beginning.”

Reviewing each application and providing a Torsion Control Products-tuned coupling, designed specifically for the Durst gearbox, where required, ensures torsional vibration issues are addressed before they create problems.

“We are very excited about this new system approach,” said John Locarno, Durst’s Global Sales and Marketing Manager. “Customers are guaranteed reliable transmission of power, economical installation and protection of coupled equipment. In addition, along with the convenience of one-stop shopping, there is none of the finger pointing that can occur when obtaining different system components from multiple suppliers.”

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
