Hydraulic Helical Gears Rotary Actuator

ECKART E1 Series (100 bar)

  • Torque: 2450 Nm max at 100 bar
  • Angle of rotation: 90, 180°, 270° or 360° (others on request)
  • Optimized end cushioning (option)
  • Through precise combined helical gears and low friction seals, is the E1 already from 10 bar economically applicable
  • Maximum operating pressure: 100 bar

Spot the advantages:

Low hydraulic axial load on drive shaft through small differential

  • Less load on the ball bearing, freeing it for more important task.
  • Extending the service life of the rotary actuator.

Adjustable drive shaft datum

  • If you manufacture the hub, it is not necessary to regards the exact position of the keyways.
  • The total angle can be re-adjusted at any time.

Ball bearing

  • In spite of the possibility is the radial and axial power through the application of ball bearings by low hydraulic pressure warranted.

Highly perfected end cushioning for absorption of kinetic energy

  • Negating the needs for expansive proportional or servo controls with virtually identical characteristics.

Large-area press-fit joint

  • Assuring positive power/torque transmission even at peak load conditions.

Through shaft

  • The axial force required for mounting the shaft on the hub can be exerted at the end of the shaft, preventing destruction of the ball bearing.
  • The mounting of components for the pivoting angle monitoring is possible without problems.

Wear-resistant moving parts

  • Long service life of the rotary actuator through extended-period nitriding.
  • Excellent sliding characteristics of the gears.

Modern sealing technology

 

  • Extended service life of seals.
  • Increased safety, also with regards to the environment.
  • Suitable for most fluids.
  • All installation places have the smallest possible tolerances, in case of that, do we avoid a gap extrusion of the seals.
  • No internal leakages through solid seals enabling the load to be held in any intermediate position.
