19 Installation Before installation: All surfaces should be cleaned carefully with rust proof liquid. When installing, please avoid dust and foreign matter come into the coupling, this will hurt mating surface between gears and also influence behavior of coupling. How to install the coupling on the shaft: There are 3 ways to mount gear hub on the shaft: normal pressure push, high pressure push and shrinkage fit after oil boiled. You should choose the way acc. tolerance fit between shaft and hub. If you choose the way of shrinkage fit, please do not heat gear directly and temperature on the gear should not be over 250 C. When connecting gear ring with fit bolts, please keep holes of two gear rings mating acc. mark on the gear ring. When mounting seal cover, please use incidental bolts, nuts and washers When mounting key, please use seal gum to avoid oil or grease leakage from clearance between key and key way. Installation error: Reduce installation error is an important factor for regular service of the coupling, allowable installation error value should be less than 1/30 1/50 of allowable compensate value of coupling. When installing, please use dial gauge, gauge block and feeler to measure installation error and keep installation accuracy within the allowable value. Lubrication: Mating surfaces of gears should have oil film when working, coupling should not have oil leakage phenomenon. Lubricating oil or grease (see table below) Recommanded lubricants (-20 C C) Manufac-t urer Name Manufac-t urer Name Klüber Centoplex EP 2 AGIP Longtime Grease 2 BP Energrease LS-EP 2 ARAL Aralup HLP 2 / SL Shell Alvania E(LF)2 CASTROL Spheerol EPL 2 Mobil Mobilux EP2 FUCHS RENOLIT H 443 HD 88 Please change lubricating oil or grease by 3 months interval when using coupling in first time and change oil or grease in 6 months interval after it. Please check oil or grease consumption in every half month and supply oil or grease in time. Please change seal ring in time when it damaged and take care of surface of seal ring when changing it.
