Actuator Drive Train and Housing

Drive Train: Power and Durability

drive-trainBeck’s durable gear train maintains accurate, consistent positioning even under the demanding conditions of an active control loop.

    • Gear trains employ a unique, all spur gear construction using only heat-treated alloy steels and ductile iron.
    • Efficient, wide-faced spur gears ensure long life and eliminate wear-induced backlash and positioning inaccuracies common in worm gear and “Scotch-yoke” designs.
    • Integral self-locking mechanism ensures that actuators hold a minimum of 200% of rated torque with the motor de-energized.
    • Durable design provides up to 4 days of protection against intermittent or extended accidental stalls.
  • Stall protection is provided by the DCM. If the motor tries to run in one direction for more than 300 seconds, the DCM-2 will shut off power to the motor and a status indication LED will activate indicating a stall.

Housing: Superior Protection and Convenient Access to Components

features-actuator-cutawayBeck actuators feature a cast aluminum body with individual compartments to protect components from moisture and dirt, and allow easy access for installation and calibration.

  • Precision-machined aluminum alloy castings with corrosion-resistant polyurethane paint provide a rugged, dust-tight, weatherproof Type 4X enclosure.
  • Individual compartments protect all major components: Motor, DCM-2, CPS, gear train and installation wiring terminal board.
  • Gasketed covers provide extra protection for abusive indoor environments and harsh outdoor climates.
  • Each compartment can be accessed without exposing other components to the environment.
  • Output and Handwheel shafts are sealed with weatherproof, double-lip cartridge seals.
