perat- ing instructions has been developed to drive twin-screw extruders. The gear unit has been approved for only one direction of rotation. The direction of rotation of the motor must match the direction of rotation arrow marked on the input shaft of the gear unit. 3.2 Housing 3.2 Housing Introduction The housing is made of cast iron. When specified, the housing can also be manufactured out of steel. The housing is multiple-part component. The standard version of the gear unit housing has the following features: Attachment points for moving the gear unit Inspection and assembly cover for inspection and oil filling Oil sight glass for checking the oil level Oil drain screw for changing the oil Air filter for ventilation and bleeding More information Further information and detailed illustrated description of the gear unit can be found in the drawing in the complete documentation for the gear unit. 3.3 Lubrication and cooling 3.3 Lubrication and cooling The gear unit is lubricated and cooled by pressure lubrication provided by mounted or sep- arate oil supply system. For gear units with an oil supply system, all of the monitoring devices must be connected up and function-tested before commissioning. NOTICE Damage to the gear unit due to insufficient oil The gear unit or parts of the gear unit can sustain irreparable damage if they are not sup- plied with sufficient quantity of oil. The oil supply line must be monitored by separate pressure monitor. Description 3.3 Lubrication and cooling 2 Edition 0/2 A5-0 enPrinciple of operation The gear unit has the capacity to hold all of the oil required to provide lubrication and cool- ing. The external oil supply system draws in the oil and pumps the cooled and cleansed oil back to the gear unit. The oil passes to the rolling-contact bearings and gearing via lube oil holes.
