  • Pulley Conversion -- Value Engineering Replaced Both High-Cost Steel and Plastic with Zinc
    nut and a molded plastic cup. The pulley threads onto the end of drive shaft and has an envelope size of 1-3/8" diameter by 1-1/16" length. The motor drive belt fits between the nut back plate and the attached cup. The groves in the recess match up with those on the belt's underside and power the belt
  • A Change in Speed Control Strategy Ramps up Production for Steel Company
    adjustments. The TSA team decided to upgrade the speed controls by using a variable speed drive (VSD), but they weren't sure how to size the new motor and drive. They also wanted to make sure the upgrade didn't introduce undue complexity to machine operation.
  • A Finer Control of Linear Motion
    less than pull-out torque. refers to the number of pulses/second applied to the motor windings. Pulse rate equals the motor-step rate. is the number of steps the motor takes in 1 sec (sometimes called "steps/second "), determined by the frequency the motor drive produces. is angular rotation produced
  • How to make bearings last in electric motors
    ruined when a motor is used improperly. For example, the deep-groove ball bearings optimized for in-line couplers can overload if motors fitted with them drive a belt pulley. Likewise, motors containing roller bearings for heavy belt loads may prematurely fail when run with an in-line coupler
  • Rolling-ring actuators spool up production, cut costs
    . No more. Jennings now offers take-up reels as an option with the machines. It chose for the traversing portion a rolling-ring linear actuator from Amacoil Inc., Aston, Pa. ( ). The rolling-ring design allows the use of a single, unidirectional motor to drive a simple pulley system. The pulleys

  • Dubbel
    The drive shaft in the bucket elevator head carries driving drum or drive rollers , drive chain wheels or working breed.
  • Dubbel
    The drive shaft at the bucket elevator head, the driving drum, drive rollers carry or drive wheels.
  • Drive solutions
    Leads through the diameter d of the drive roller of the conveying distance from 350 mms this to a number of revolutions of 2,543 rad/s .
  • Transport and storage logistics
    Drive roller .
  • Manual logistics
    Longer roller conveyors require several of these drive rollers on account of the limited drive power (< 100 W).
  • Energy management in the motor vehicle
    It must be transmitted over the moment of inertia of the drive roller in connection with an electrical moment of the E machine as consistently as possible to the roller test bench.
  • Manual mechanical engineering
    Calibrated chains require the operated drive rollers diameter of which can be selected small but the snagging number must amount at least to 5.
