MOTOX gearbox - DS TECH

Service and maintenance8.3 Replacing bearingsThe lubricants suitable for use in the gearbox are listed in the Operating InstructionsBA 7300 "Gearbox Lubrication". We are familiar with the composition of these lubricants and,as far as we are currently aware, they possess state-of-the-art properties with regard to loadbearingcapacity, corrosion resistance (FZG test DIN 51354 = force level > 12), resistance togray staining and compatibility with seals and interior paint finishes as necessary for the typeof gearbox concerned. Therefore, we advise our customers to select one of the lubricantslisted in this table, taking into account the VG class specified on the rating plate.If, following agreement, gearboxes are filled at the factory with special lubricants for thespecial applications referred to above, this is shown on the rating plate.The warranty conditions are valid only for the lubricants listed in the Flender OperatingInstructions BA 7300. If you decide to use a different oil, you are responsible for the technicalsuitability of the lubricant.8.3 Replacing bearingsATEX version gearboxesBearing life depends very much on operating conditions. It is, therefore, verydifficult to calculate it reliably. In the operating conditions specified by the operator,bearing life can be calculated and indicated on the rating plate. If no information isgiven, changes in vibration and noise pattern can serve as an indicator that animmediate bearing replacement is necessary.8.4 Checking the gearbox for leaksOil or grease escaping in small quantities from the shaft sealing ring should be regarded asnormal during the running-in phase of 24 hours running time.If the quantities escaping are significant or leaking continues after the running-in phase, theshaft sealing ring must be replaced to prevent consequential damage.Shaft sealing rings are subject to natural wear. Service life depends on operating conditions.We recommend that shaft sealing rings are included in periodic maintenance and servicingwork on the system.BA 2010Operating Instructions, 05/2011 73
