MOUNTING DETAILS OF 53 TYPE GSA ALTERNATOR WITH SINGLE BEARING The dimensions of diesel engine's flywheels and its cover use in gensets should comform SAE J620d and SAE J617c standards. In GSA alternators, the disc mounted to the engine's flywheel and the adaptor of alternator mounted to the engine's flywheel cover are design according to these standards. The SAE standards of engines that will used in genset should be informed to us while ordering. If the SAE number of diesel engine's flywheel and its cover are not known, please find the SAE numbers of your engine's flywheel and its cover by comparing the dimensions given in SAE J620d and SAE J617c standards. The adaptor and disc combinations of 53 type GSA alternators are given in the table below :
MOUNTING DETAILS OF 53 TYPE GSA ALTERNATOR WITH DOUBLE BEARING In the gensets with double bearing alternators, the power is transmited to the alternator's rotor with the coupling mounted to the end of alternator's shaft. The coupling should be elastic to minimise combustion of the diesel engine's effect on the alternator shaft. Gensan produces GK type couplings for mounting GSA alternators to diesel engines. GK 270 coupling is used between 225 - 275 KVA , GK 300 coupling is used between 400 - 500 alternators. At the end of the alternator shaft, there is a screw hole according to DIN 332 standard for mounting or dismounting purposes of the pulley or the coupling. Mounting of the pulley or the coupling can be done by placing a mounting apparatus to the screw hole. For easier mounting, the coupling or the pulley should be machined to H7 tolerance and heated to 120-150ºC. Avoid any kind of heavy hammering to prevent the ball bearings from damaging. If the Pulley-Belt System is used for transmission in GSA Alternators which are greater than 50 KVA, special ball bearings must be used. In certain cases please inform us while ordering. |
