Transcyko CRP Co-Rotating Twin Screw Extruder Gearboxes
Transcyko CRP co-rotating twin screw extruder gearboxes give you precision power transmission for demanding rubber and plastic extrusion processes. The high torque density and thermal resilience of our CRP gearboxes increases load bearing capacity in a compact format without compromising service factors or routine maintenance requirements.
Two types of CRP co-rotating twin screw extruder gearbox
Transcyko manufactures two types of CRP co-rotating twin screw extruder gearboxes, CRPA and CRPB, which are designed to provide different torque densities. Both CRPA and CRPB twin screw extruder gearboxes feature high power density, precision helical bevel gears that deliver synchronised, high-torque power transmission simultaneously to both screws.
- CRP co-rotating twin-screw extruders feature reduction ratios from 1.5 – 5.0
- CRPA co-rotating twin screw extruders for high torque density 14-16 Nm/cm³ for each shaft
- CRPB co-rotating twin screw extruders for medium torque density 12.5 Nm/cm³ for each shaft
Our twin screw extruder gearboxes maintain precise speed ratios even under continuous heavy load. This is of critical importance for plastic and rubber extrusion lines, because even minor variations in screw speed results in imperfect mixing and inconsistent flow. Transcyko CRP co-rotating twin screw extruder gearboxes are included in our comprehensive range of rubber extruder gearboxes.
Precision power transmission for heavy duty rubber & plastic extrusion
The co-rotating twin screw configuration gives you precision power transmission as both screws turn in the same direction at identical speeds. This makes Transcyko CRPA and CRPB the perfect choice for heavy duty and demanding rubber and plastic extrusion, delivering the consistent intermeshing that makes CRP gearboxes ideal for compounding, mixing, and reactive extrusion.
