nterference fits and parallel keys. These types of joints transmit the torques generated with adequate reliability. 5.4 Lubrication 5.4.1 Splash lubrication Unless agreed otherwise by contract, the teeth and bearings are supplied adequately through splash lubrication. The gear unit thus requires very little maintenance. 5.4.2 Forced lubrication With high input speeds or high peripheral speeds at the toothed systems, the splash lubrication can, depending on the order, be supplemented by or replaced with forced lubrication. The following configuration is available: Add-on oil-supply system (fixed to the gear unit, see item 5.7. Note For gear units with combined splash and forced lubrication, it is necessary to connect the pressure monitor as an opening contact or closing contact prior to start-up. "" bar 1P -* PXPressure according to the information in the order-specific documentation. To be connected as an opening or closing contact as required. Note When operating and servicing the components of the oil supply system, observe the operating instructions of the components. For technical data, refer to the data sheet and/or the list of equipment. For detailed illustration of the gear unit and oil-supply system, refer to the drawings in the gear unitdocumentation. 2 / 7BA 5 en 0/2.5 Shaft bearings All shafts are fitted in rolling bearings. 5.6 Shaft seal Radial shaft sealing rings or special seals on the shaft outlets prevent oil from escaping the gear unit or dirt from penetrating the gear unit. 5.6.1 Radial shaft seal Radial shaft seals are the standard type of seal. They are preferably fitted with an additional dust lip to protect the actual sealing lip from external contamination. NOTICE Property damage Destruction of the radial shaft sealing ring caused by high dust concentrations is possible. Radial shaft sealing ring is not to be used in high concentrations of dust.
