ANDCO ActuatorsELECTRIC ROTARY ACTUATORSThe QR Series Posi-Tork Rotary Actuators are completely self-contained, electric mechanicaldevices. Designed and fabricated for dependable, long-life operation, these actuators are usedfor positioning, automation of material handling or flow control equipment. Series QR PosiTork Actuators are driven by a high-starting torque, low inertia motor. The motor rotates theoutput drive sleeve through a worm gear set and single reduction spur gearing.Upon completion of travel, the gear driven position limit switch interrupts power to the motor.If during actuator travel, some external obstacle prevents movement, the torque limit switchwill interrupt power to the motor.817652431. Adjustable Position Limit Switch. A two positiongear driven limit switch for end of travel actuatorshut-off is included as standard. Each position isindependently adjustable and can be set anywherewithin the full actuator travel. The heavy duty rotarydrum, double break switch with wiping contacts,features a patented mechanism that ensures internalgear engagement after adjustment.6. Adjustable Torque Limit Switch. An adjustable torqueswitch for each direction of travel is provided asstandard. The switch assembly will automaticallyshut-off the actuator if the set torque is exceeded.The switch protects driven equipment from damagedue to excessive torque and can also be used as amechanism for positive seating.2. Weatherproof and/or Dust-ignition proof (Class II,Division 1 & 2, Groups E, F and G).8. Heavy duty motor, TENV, NEMA D design,high-starting torque, low-inertia motor provideshigh breakaway torque and good positioningcharacteristics. Class F insulation is standard.3. Anti-friction bearings throughout, including theoutput drive sleeve.4. Torque limit disc springs and spring limit sleeve toprevent total spring deflection.5. Non-backdriving high strength worm gear set.7. High strength alloy steel cut gears.Other features: Plated external hardware. Permanently lubricated. Electrical components prewired andterminated inside actuator.
