HSB 04 / V SZ

The swivel motors with attached hydraulically released spring-applied multi-disc brake are recommended if a swivel position must remain unchanged once it has been reached – 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 lines can cause time differences between the switching off of the swivel motor and the application of the released brake caused by spring force. In order to provide our customers with the right drive for all areas of application, the HSB swivel motor is available in a total of 5 different versions. We have listed the most important data below. You can find all further details in our data sheet.

The use of servo-hydraulic controls can significantly extend the range of applications for swivel motors. Larger loads can be slewed in a shorter time than is possible with purely hydraulic systems, where the damping travel is fixed. In conjunction with such a control system, the acceleration and braking behavior of the swivel motors can be specifically adapted to the requirements. This means that even fast and very precise movements with large masses can be safely mastered. We offer customized solutions for a wide range of applications. Our qualified team will be happy to advise you on design and realization.

Swivel motors from 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 swivel motors in this series are often also suitable in combination with simple hydraulic circuits if the inertia 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 drive for all areas of application, the HSG swivel motor is available in a total of 11 different versions. We have listed the most important data below. You can find all further details in our data sheet.

The output shaft of the HSH swivel motors has radial and axial hydrostatic bearings. Here, radially and axially arranged bearing pockets are supplied with pressurized oil via a separate pressure connection. As a result, the output shaft is centered radially and axially between liquid cushions and all metallic contact surfaces are permanently separated from each other by a thin liquid film. This eliminates wear caused by 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 sensors, these actuators are preferably used in controlled systems in which disturbance variables such as 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 numbers of load cycles where an interruption, e.g. due to the replacement of internal seals, is not permitted.
