Our HSG series rotary actuator can be used for any installation position. In the HSG series, the rotary actuator has no end position damping or swivel angle limitation. Rotary actuators in this series are generally suitable when program sequences such as acceleration – travel – deceleration in open-loop or closed-loop controlled systems are determined via proportional or servo valves. The rotary actuators in this series are often also suitable in combination with simple hydraulic circuits if the inertial forces occurring are small, e.g. when opening and closing emptying systems, actuating valves, placing and removing workpieces, swiveling load handling devices and much more.

In order to provide our customers with the right actuator for all areas of application, the HSG rotary actuator is available in a total of 11 different variants. We have listed the most important data below. All further details can be found in our data sheet.

Our HSG series rotary actuator can be used for any installation position. The rotary actuator also fulfills the function of end position damping with or without adjustable swivel angle limitation. This refers to the braking and deceleration of the swivel movement to a standstill. For damping, the cross-section of the bore for the outflowing medium is continuously reduced and the moving masses are thus hydraulically braked. The end position is reached when the bore is completely closed and the medium can no longer flow out.

In order to provide our customers with the right actuator for all areas of application, the HSE rotary actuator is available in a total of 6 different variants. We have listed the most important data below. All further details can be found in our data sheet.

Our HSB series rotary actuator can be used for any installation position. The rotary actuator with attached hydraulically released spring-applied multi-disc brake is recommended if a swivel position once reached must remain unchanged – even over an unlimited period of time – despite the effect of a load torque. The brake is used solely to hold the load. It should only be noted that large transmission delays in the cables can cause time differences between the rotary actuators being switched off and the released brake being applied via spring force.

In order to provide our customers with the right actuator for all areas of application, the HSB rotary actuators are available in a total of 5 different variants. We have listed the most important data below. All further details can be found in our data sheet.

Our rotary actuator with servo-hydraulic control from the HSL series can be used for any installation position. By using servo-hydraulic controls, the range of applications for rotary actuators can be significantly extended. Larger loads can be swiveled in a shorter time than is possible with purely hydraulic systems in which the damping paths are fixed. In conjunction with such a control system, the acceleration and braking behavior of the rotary actuators can be specifically adapted to the requirements. This means that even fast and very precise movements with large masses can be safely controlled.

We offer customized solutions for a wide range of applications. Our qualified team will be happy to advise you on design and realization.

Our rotary actuator from the HSS series can be used for any installation position. Like all Hense rotary actuators, this rotary actuator is designed according to the rotary vane principle. The drive shaft has axial and radial plain bearings in coated bushes. The coating used is tribologically optimized and ensures low wear. Sufficient lubrication of the bearing points is ensured by the supplied hydraulic oil. To reduce internal motor friction, the hydraulic separation of the working chambers in this series is partly achieved by means of pressure and viscosity-dependent throttle sections.

HSS motors are ideal for generating oscillating swivel movements in the frequency range with small angular amplitudes in controlled systems. The HSS series is therefore recommended for use whenever semi-dynamic torsion tests need to be implemented reliably and cost-effectively.

Servo-hydraulic hydraulic oscillator
In conjunction with other high-quality components, such as servo valves, pulsation accumulators and high-resolution angle measurement systems, the hydraulic oscillator is designed to generate alternating torsional loads.

Our HSH series rotary actuator can be used in any installation position. The output shaft of the rotary actuator has radial and axial hydrostatic bearings. Radial and axial bearing pockets are supplied with pressurized oil via a separate pressure connection. As a result, the output shaft is centered radially and axially between fluid cushions and all metallic contact surfaces are permanently separated from each other by a thin film of fluid. This eliminates wear due to metallic friction in any operating state, even at zero speed compared to hydrodynamic plain bearings.

In conjunction with highly dynamic control valves and angle of rotation transducers, these actuators are preferably used in controlled systems where disturbance variables such as internal friction and the stick-slip effect must be reduced to a minimum. Furthermore, due to the lack of internal seals, they are ideal for test series with large load cycles where interruption, e.g. due to the replacement of internal seals, is not permitted.

The HSH series is therefore predestined for use as a servo-hydraulic hydraulic transducer and as a hydraulic tensioning motor in tensioning test benches.

Tensioningtestbench
The hydraulic tensioning motor is integrated into a closed tensioning circuit with power feedback. The rotary actuator rotates and is supplied with energy via a multi-path rotary feedthrough, while it applies a static, quasi-static or dynamic torsional moment to the rotating strands in a controlled manner.

In the serial arrangement, a vertically aligned linear drive shaft (double-acting linear cylinder) is mounted on the vertically aligned rotary drive shaft (swivel motor), i.e. the piston rod of the cylinder and the output shaft of the swivel motor are mechanically coupled via a movable shaft-hub connection.

The pallet holder is lifted by the piston rod, which also serves as a bearing for the pallet holder and safely absorbs all the forces generated during asymmetrical loading.

We offer customized solutions for various applications. Our qualified team will be happy to advise you.

In principle, in the parallel arrangement, the vertically aligned rotary drive axis (swivel motor) is placed next to the linear drive axis, which is also vertically aligned and preferably consists of two linear cylinders. The swivel motor is inserted and lifted in a motor support mounted separately in linear guides.

The pallet holder is mounted directly on the shaft of the swivel motor or in a separate pivot bearing in the motor support. Tilting moments caused by large asymmetrical loading conditions are thus safely absorbed.

The L-10 series has our smallest and most compact hydraulic drive with helical gearing. With its extremely high axial load capacity in a slim, cylindrical design with flange mounting and drive, the ultra-compact L-10 series is ideal for applications with limited space. Helac’s sliding spline hydraulic technology with helical gearing is not self-locking and offers both high impact resistance and high holding torque for demanding applications.

The L-10 series functions as a rotating device as well as a mounting bracket and support structure, so that no external bearing systems, brakes or locking devices are required. Available in five standard sizes with an output torque of up to 2,825 Nm at 210 bar.

The L-20 series is a particularly cost-effective solution that is suitable for a wide range of applications. It has versatile mounting options and a flange drive. Helac’s sliding spline technology with helical teeth is not self-locking and offers both high impact resistance and a high holding torque for demanding applications.

It functions both as a rotating device and as a mounting bracket and support structure, so that no external bearing systems, brakes or locking devices are required. Available in five standard sizes with an output torque of up to 4,400 Nm at 210 bar.
