Spiral Rotary Actuators
Hengli hydraulic spiral rotary actuators: six series (HBL, HBM, HBH, HBT, HBK, HBP) with more than 100 specifications. Linear piston motion is converted into rotation of the output shaft by two helical spline pairs: fixed nut — hollow screw — output screw. Output torque is 200–76,000 N·m at 21 MPa, holding torque is two times the output torque or more, torque and speed are equal in both directions; built-in axial and radial bearings carry cantilever and straddle loads. An optional counterbalance valve prevents uncontrolled rotation on line failure and overload.
