protection. NOTICE Property damage Any damage to the coating may cause failure of the exterior protective coating and corrosion.Ensure that the coat is not damaged. Note Unless otherwise agreed by contract, the interior preservation is guaranteed for 6 months, and theexterior preservation for 2 months, provided that storage is in dry, frost-free sheds. The warranty starts on the day of the delivery or the notification of readiness for delivery (see section 1. "Technical data" in the gear unit documentation). For longer periods of storage (> 6 months) we advise regular checking and, if necessary, renewal of the interior and exterior preservation (see item 7.. In case of re-preservation the output shaft must be rotated at least one turn to change the position of the rolling element in the bearings. The input shaft must not come to standstill in the same position as before rotation. This procedure must be repeated and documented every 6 months until start-up. Note The record must be kept with these instructions. 1 / 5BA 5 en 0/2. Technical description Observe the instructions in section 3. "Safety instructions"! 5.1 General description The gear unit described is "FLENDER girth gear unit" designed for driving tube mill by means of girth gear. It is load-sharing helical gear unit. Its housing is not closed. Mounted on the shaft of the last stage is an output pinion. Both output pinions engage direct in the girth gear and are constructed to be able to compensate for unavoidable tilting and wrenching movements of the girth gear. This enables good contact pattern over the whole teeth during operation. The drive shaft of "FLENDER girth gear unit" is drawn out on both sides. Note All operating instructions included in the delivery must be observed for the operation and maintenance. Find the technical data in the order-specific documentation, equipment lists and drawings. 5.2 Lubrication Both the teeth and the rolling bearings are force-lubricated by an oil supply u
