If not otherwise specified by the customer, they are balanced dynamically at n = 2000 RPM according to classification Q 16 of the VDI recommendation 2060. 9. Transport and storage – installation information 9.1 Transport and storage To retain the high degree of balance, the drivelines must be protected during trans- portation or storage from blows or jolts. It is recommended to transport them in horizontal position. When transporting them vertically, appropriate measures must be taken to avoid separation of the driveline halves. A horizon- tal position is also preferred for storage of the driveline, since doing so eliminates tipping over and possible damage. Never store drive- lines on the floor, but if possible, on wooden shelves. In case of prolonged storage, blank metal parts must be checked for corrosion, and if necessary, treated again with a corrosi- on inhibiting oil. 9.2 Installation Before installing drivelines, all traces of rust inhibitor, dirt and grease must be removed from the flange surfaces to preserve the coef- ficient of friction vital for torque transmission. Drivelines should not be separated at the spli- nes and the halves interchanged, otherwise the quality of balance is greatly impaired. For the same reason, balance plates should not be removed. Prior to installing drivelines, it must be che- cked that they are assembled correctly, which means that the marking arrows on the splined shaft and splined hub must face each other (See also notation on Page 170). These drivelines should be arranged such that the spline, whenever possible, is protected from dirt and moisture. As a rule, this means installing the driveline according to the sketch above, where the spline seal points down- wards so that spray water hitting it runs away from the spline. Fork position Offset by 90° If two or more drivelines are arranged in se- ries behind each other, it is recommended that they be mounted offset to each other by 90°. Doing so will at least partially cancel to the outside the effect of the mass acceleration forces caused by the fluctuation motion of the driveline center parts. The necessary bolting hardware for flange mounting can also be supplied by us on re- quest. For bolt grades and necessary bolt tor- ques, see page 74. When torquing down the bolts, if possible, a torque wrench should be used and the torque should be applied evenly in a crosswise pattern. Our drivelines are delivered grease-packed, ready for installation. However, after prolon- ged storage, it is advisable to reapply grease before putting them into service. 10. Safety instructions and Maintenance 10.1 Safety instructions The operator has to take corresponding safety precautions that will exclude dangers to per- sons and material by rotating drive shafts or their components. The user or operator hast to observe the legal safety regulations and has to make arrange- ments before beginning the maintenance- work. 10.2 General maintenance information ELBE drive shafts will be delivered as fully fi- nished power units, are ready for use greased and balanced. To guarantee the characteristics specified in the documentation, the condition upon delivery may not be changed. The maintenance-cycle of the drive shafts depends particularly on the application con- ditions. Above-average load, variations in tempera- ture and the effect of dirt and water render it necessary to observe shorter maintenance intervals to guarantee the safe and efficient application. We recommend coordinating the inspection intervals of the drive shafts with the ones of other machine parts or with the service inter- vals of the machine or of the vehicle. Inspection and maintenance are required at least once a year.

Take suitable measures to avoid that drive-shafts-shares slide apart uninten- tionally and cause injuries or damage. • Fast mode or/and long shafts should be lined with protection devices like safety shackle and guard and protected against touching or point potential dangers explici- tly out. • Don’t place weights onto shafts in stand- still, don’t place, hang or fasten tools or other objects on the shafts. To avoid damages or dangers observe the fol- lowing basic information : • The permitted operating speed may not be exceeded. • Don’t exceed the permitted angle of deflection . • In case of shafts with length extension the maximum permitted X-value may not be exceeded. It is recommended to use 1/3 of the complete length extension. • The drive shaft has to be checked regularly for modified running noises and vibra- tions and if necessary to check the chan- ging of the joint slackness and of the length extension in standstill. • The balance status of drive shafts may not be changed. • Don’t make modifications or unauthorized repairs without the written approval of the manufacturer, as dangers for humans and material result and any claim of war- ranty becomes void. • Drive shafts may not be cleaned with pressure water or steam jet to avoid da- mage of the seals and to prevent the pene- tration of water and dirt. • When cleaning don’t use aggressive cleanser . • Protect plastics-coated profiles and sliding surfaces against mechanical, ther- mal and chemical damages. Sliding sur- faces for seals have to be covered before colouring. • The drive shafts may only be installed in fluid or solid media with written approval of the manufacturer. • Local heating of the drive shafts (e. g. flame cleaning of colour residues) must not be carried out to avoid significant changes of the true running characteristics.
