Worm-screw drives can be divided into two basic groups:
– screw jacks
for vertical positioning of objects,
– worm and screw drives
to move the machine elements in any direction.
Both the screw jacks and screw drives may have
an electrical or manual drive.
They are based on the structure of previously produced MR worm gears.
Reinforced body, thrust bearings and special guides of the bolt carrier have changed the standard drives into professional actuators with capacity up to 5 tons.
MRP screw actuators are produced in four sizes:
MRP-26 with a statical capacity of 500 kg,
MRP-32 with a statical capacity of 800 kg,
MRP-40 with a statical capacity of 1500 kg,
MRP-63 with a statical capacity of 3500kg,
MRP-80 with a statical capacity of 5000 kg;
MRP-100 with a statical capacity of 10000 kg,
in the development there are larger actuators available on request.
The maximum total length of the carrier bolt is 3 m and a maximum lifting speed is 2.6m/min (~44 mm/s).
– Drives of slow-moving elevators,
– Positioning drives for technological equipment units,
– Truck and chimney damper drives and various hoists with low work intensity.
