  • Make It Last: Maximizing the Service Life of Industrial Air and Spring Actuated Friction Clutches and Brakes
    Determining how long a friction clutch or brake will last has much to do with application. Cycle rates, revolutions per minute and the air pressure required to produce the torque to drive or stop the load are just a few of the considerations. Assuming the unit has been properly sized
  • Application Considerations: Pneumatic or Electric Brakes & Clu
    What are the main differences between pneumatic brake and clutch assemblies versus electric brake and clutch assemblies? Pneumatic clutches and brakes use air cylinders to actuate and provide the normal force to transmit torque. They require 30-80 PSI of a clean compressed air...
  • Electric clutches on the go
    into the rotor and armature. Slots, called banana slots, allow the flux to contact the rotor and armature in more than two places. Multiple points of flux connection increase the torque of a clutch. Switching off power to the coil disengages the clutch. Springs between the armature and hub allow an air gap
  • Pulse Tool Selection Best Practice: Focus on Ergonomics, Productivity and Low Maintenance Cost
    A Pulse tool has the speed of an impact wrench with nearly the repeatability of a clutch based shut-off tool. Containing precision-machined parts the pulse unit is a sealed chamber that is filled with a formulated hydraulic fluid. Pulse blades with a custom designed precision roller push the fluid
  • The Basics of Electromagnetic Clutches and Brakes
    on magnetic field strength, air gap, and inertia. * Burnishing increases initial clutch or brake torque, and overexcitation cuts response time. Getting a grip on clutch and brake selection , " MACHINE DESIGN, Sept. 9, 1999 People use electromagnetic (EM) clutches and brakes every day and often don't
  • A fan of fuel savings
    permanent magnets to couple to and rotate the fan at a particular speed. Powering a coil rotates the fan at shaft speed. Viscous-type fan clutches provide a certain amount of fan control. Here, a bimetal strip on a fan hub senses temperature changes of air passing through the radiator. The strip

    performance. Centrally located injectors are said to deliver better fuel-air mixing than the side injectors of previous generations. Twin-independent variable-camshaft timing (TI-VCT) also helps cut fuel consumption by about 5% while delivering good low-end torque. These systems combine with a dry
  • 2005 Saturn Ion Red Line
    several firsts for Saturn. Besides the Eaton helical Roots supercharger, theres an air-to-water intercooler to reduce the temperature of air entering the engine. Cooler air compliments the performance of the supercharger. Also, electronic throttle control replaces the cable between the gas pedal and motor
