TRANSFER CASE OF TWO-SCREW EXTRUDER, TWO-SCREW EXTRUDER DRIVE AND TWO-SCREW-EXTRUDER Russian patent published in 2008 - IPC F16H1/22 

FIELD: engines and pumps.

SUBSTANCE: invention can be used for transmission of torque in mechanisms with closely-spaced and axially-loaded working tools. The said extruder transfer case consists of housing (19), gear rim (14) with external and internal gearing, two driven shafts, i.e. gears (15,16) in mesh with the internal gearing of gear rim (14), bearing units, driving shaft (13). Housing (19) has a base with side and end face walls and a removable cover. The housing end face walls have through holes to accommodate the driving shaft bearing units and driven shafts, that is gears. The two-screw extruder drive has a motor and a transfer case.
