Ondrives Introduces Titanium Precision Spur Gears

Ondrives' latest power transmission catalogue, released in February 2011, features a range of titanium precision spur gears, suitable for lightweight applications. 'We are constantly updating our gear range in order to make them as extensive as possible, offering customers more choice than ever in terms of materials, types and sizes,' said Amanda Laughton, marketing manager. Titanium has been chosen as it has a low density and is a strong, lustrous, corrosion-resistant material with a silver colour.

According to the company, the two most useful properties of the metal are its corrosion resistance and its high strength-to-weight ratio. Unalloyed, titanium is as strong as some steels, but 45 per cent lighter in weight, making it suitable for lightweight applications. At present, the titanium precision spur gear range starts at a 0.5 module going up to 1.5 as standard. Larger sizes are planned for the future.

All are made to Quality Grade 7e DIN 58405 (AGMA Q11), with other grades available on request. Teeth numbers start at 20 going up to 250, and optional extras such as different bore sizes, tapped holes, pin holes and keyways are available where required. Ondrives can quote to customers' special requirements where necessary and offer a free technical advice service on a no-obligation basis.

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.
