DSH screw jack
Product description
DSH screw jack
Conventional screw jack applications consist of one or more
screw jacks. Usually they are driven by one electric motor and
typically connected via drive shafts or couplings resulting in
efficiency losses within the drive train.
Screw jacks fitted with worm/wormwheel or bevel gear sets
often reach their maximum limit when operating with high duty
cycles or high linear speeds. These are two of the main reasons
for the development of our new quiet and efficient lifting system.
After a long development program with the supprt of local
universities the new DSH screw jack has been created.
The INKOMA-DSH screw jacks have no internal gear system.
Instead a special Torque motor is used to directly drive the
ballscrew spindle resulting in smooth backlash free rotation. In
the DSH system there are virtually no mechanical losses.
Specially selected bearings ensure the spindle can withstand
both tensile and compressive loads. The compact drive unit
has a rigid construction and is suitable for high dynamic
applications. Cycle times of 7 cycles per second and lifting
speeds of 32m/min are achievable. Repeatable positioning
accuracy is also very high. The DSH-units can be synchronised
when working together within a system, allowing the screw
jacks to be positioned at different levels within the application.
The DSH-system has high energy efficiency. During operation
the torque motor is used to control the speed and hold position
of the ballscrew spindle. An integrated brake is also available
for increased safety. The spindle can be mounted on either side
of the DSH unit.
The DSH unit is available with a complete control system
(Siemens system used on standard version). Alternatively other
manufacturers equipment can also be specified.
In addition to the basic versions, customer specific executions
are also possible e.g. spindle diameter, spindle pitch, mounting
dimensions. Please contact us with your special requirements.
