Extruder Gear Box

We provide extruder gearboxes in double reduction parallel shaft horizontal models that have hardened and ground gears in double reduction. Especially used in plastic industry, these are capable to transmit the high torque required for pressuring and plasticising modeling materials and also to absorb high axial thrust load through built in spherical roller thrust bearing. The horizontal model of the extruder gear box satisfy requirements encountered in single screw extrusion process.

Features:
* Rugged construction, made of close grain cast iron
* Built-in spherical roller thrust bearing
* Shafts are mounted on precision bearings to prevent oil leakage and dust entry
* Helical gears and pinions are flank ground to ensure accuracy and noise free running
* Shaft extension are fitted with spring loaded rubber seals to prevent out flow of oil
* Lubrication system is self contained by automatic splash (Recommended oil is of viscosity grade ISO: VG 320 with EP additives)
* Standard gear units are cooled by normal heating dissipation through convection/ radiation from externally exposed surface (Built in cooling coils are provided on demand)
* Units may be operated in either direction of rotation as per requirement
* Casting surfaces are painted with linear epoxy primer
* Alkyde semi gloss blue color painted external cast faces, thus resistant to dilute acids, alkalies, oils & solvents, sea water and temperatures up to 145o C
