  • Planetary reducers eliminate machining step to keep costs down
    . A quarterhorsepower parallel-shaft gearmotor proved too large and a servodrive was considered overkill. The solution came through use of a new planetary gear reducer from Groschopp, Sioux Center, Iowa. It operates at input speeds to 4,000 rpm for servolike performance at about the same cost
  • Definite and Special-Purpose Motors
    of a gear-reduction unit with an integral or flange-mounted rotor. The main advantage of a gearmotor is that the driving shaft may be coupled directly to the driven shaft. Belts, pulleys, chains, or additional gearing to step down motor speed are not needed. Also, coupling or belting of a motor
  • Reinvented wheels support heavy loads
    , traditionally, the first step is to determine the wheel size, then design or select the proper axle. Engineers must then establish the correct pillowblock bearings for support based on the axle diameter, distance, load, and speed, and design the car's undercarriage to support the entire package
  • Medical Device Link . Showstoppers
    developed and moulded by Pfeiffer GmbH for Glaxo Wellcome. The machine, which assembles the needle jig and needle within the moulded nasal actuator, ensures 100% quality control after each step and ejects final samples for quality assurance processes at random or selected intervals. The rotary indexing
