18. LUBRICANTS RT/MRT gear units are lubricated by running the worm wheel or the worm in oil in combination with oil splashing. Under normal conditions a reliable operation as well as service life and efficiency of the gear units are secured. Gearboxes sizes 30 to 80 can be used at any mounting position. Gearboxes sizes 100 to 180 are suitable for mounting positions as shown in Table 3.1 due to positioning of the breathe plug. For any other mounting position please contact the manufacturers. RT/MRT gear units are generally supplied filled for life – ÖMV PG 460EP is a synthetic oil enabling maintenance-free operation. Under normal conditions no oil needs to be changed during service life of the gearboxes. Should a different lubricant be required, e.g. due to more demanding conditions (higher operating temperature, high speed etc.), it must be established that oil additives do not affect bronze and/or oil seals in any way. It is recommended to use synthetic oils which guarantee high service life, stability and dynamic efficiency of the worm gears. When mineral oil is used, it must be changed in certain periods. In case grease is used as lubricant, reduction of heat dissipation, reduction of efficiency and reduced lubrication of all moving parts should be expected causing higher wear of the gear unit. Recommended equivalent lubricants are shown in the Table 18.1. The oil quantity per individual type and size of gear units is shown in the Table 18.2.
