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