1,146 Schaeffler Products In Patent Applicant List

Schaeffler has announced that 1,146 of its products for use in automotive and industrial applications can be found in the German Patent and Trademark Office's list of patent applicants. According to the company, 747 of these patents are for new INA and FAG products, with the remaining 399 patents being LuK clutch products. As such, the company now ranks fifth in the German Patent and Trademark Office's list of patent applicants, which is published annually.

Among these new applications from Schaeffler are some patent-protected, technological developments, including the Uniair electro-hydraulic valve control system, developed and manufactured by INA; FAG's wheel bearing concept with face spline; and LuK's dry double clutch. In addition, the dual mass flywheel with a centrifugal pendulum-type absorber is a further product development for drive-train vibration damping. All these elements are playing a key role in reducing fuel consumption and CO2 emissions in the latest passenger vehicles, according to the company.

When considering the automotive sector, a range of products for engines, transmissions and chassis is helping to bring about improvements in fuel consumption and in reducing harmful emissions. These products contribute towards improving the energy efficiency both actively (in the case of Uniair) or passively (in the case of the double clutch transmission). Components that make a passive contribution include the dual mass flywheel with a centrifugal pendulum-type absorber or torque converters with turbine dampers.

These components reduce the idling speeds of passenger vehicles without influencing driver comfort. The noticeable reduction in idling speeds has a significant effect on fuel consumption. Mechatronics is said to be becoming more important as a discipline. This is documented by the increasing number of products and patents that relate to hybrid passenger cars and the issue of electric mobility.

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.
