6 1. Safety instructions 1.1 General notes These assembly instructions apply only to the series and sizes indicated on the cover sheet and always in conjunction with the superordinate operating instructions BA 8704 for the ARP series. 1.2 Obligations of the user All instructions and information in these assembly instructions and in the superordinate operating instructions BA 8704 for the ARP series must be observed and adhered to. Failure to observe these instructions may result in breakage of the coupling. Danger to life from flying fragments. A damaged coupling becomes an explosion hazard. Operating the coupling with damaged coupling parts is not permitted in potentially explosive environments in accordance with Directive 2014/34/EU. The operator must ensure that everyone carrying out work on the coupling has read and understood these instructions and is adhering to them in every point in order to: avoid injury or damage, ensure the safety and reliability of the coupling, avoid disruptions and environmental damage through incorrect use. During transport, assembly, installation, demounting, operation and maintenance of the unit, the relevant safety and environmental regulations must be complied with at all times. The coupling may only be maintained and/or repaired by persons qualified for the work concerned (see "Qualified personnel" on page 3 of this manual). The outside of the coupling must not be cleaned with high pressure cleaning equipment. All work must be carried out with great care and with due regard to safety. 1.3 Protective equipment All work on the coupling must be carried out only when it is at a standstill. The drive unit must be secured against being switched on accidentally (e.g. by locking the key switch or removing the fuses from the power supply). A notice should be attached to the ON switch stating clearly that work is in progress. The drive unit must be shut down as soon as inexplicable changes to the coupling are detected during operation. Rotating and/or movable drive components must be fitted with suitable safeguards to prevent contact. The operation of the coupling must not be impaired by the safeguard. Removed safety equipment must be re fitted prior to starting up. 2. Condition on delivery 2.1 Protective coating The ARPEX coupling parts delivered with these instructions are coated with a corrosion preventive agent (such as Tectyl). 6 / 14

7 2.2 Marking the coupling parts in accordance with Directive 2014/34/EU Couplings of the ARP series which are intended for use in potentially explosive environments in accordance with Directive 2014/34/EU must be marked accordingly. The precise marking and information on the application conditions of these couplings are given in the operating instructions BA They also contain the manufacturer s EC declaration of conformity. 3. Fitting 3.1 General information on fitting For information on cleaning the coupling parts and shaft ends as well as fitting the hub parts and the adaptor, see operating instructions BA Fitting the conical bolting The conical bolting is delivered ready for fitting and comprises the following components (see figure 1): Taper sleeve, inside lightly greased Taper pin, outside lightly greased Interception ring Washer Tensioning bolt Screw plug Fig. 1: Detailed view of the conical bolting 1 ARPEX flange 2 Ring 3 Bush 4 Screw plug 5 Taper pin 6 Taper sleeve 7 Plate pack / slide-bar plates 8 Interception ring 9 Washer 10 Tensioning bolt 7 / 14

8 Before fitting starts, the fitting holes and the contact surfaces for the conical bolting and plate pack on the ARPEX flange must be carefully cleaned of any dirt and rust preventive agent (such as Tectyl, paint). Observe manufacturer s instructions for handling solvent. Bolt the plate pack alternatingly in such a way to the coupling parts that the rings are in contact with the ARPEX flange and the washers on the interception rings (see figure 1). Then insert the taper sleeves from the outisde into their respective fitting holes on the ARPEX flange, as shown in figure 2, and, if necessary using a threaded rod and 2 washers (included in the delivery see figure 2), pull them through the ARPEX flange, the plate pack and the interception ring, until the collar of the taper sleeve is in full contact with the ARPEX flange (see figure 1). For fitting plate packs with integrated axial backlash limitation or vertical support, see item Fig. 2: Detailed view of the threaded rod 1 Threaded rod with 2 hexagon nuts (see figure 10 and table 4) Insert the lightly greased taper pin (re grease with lubricant indicated in table 2, if required) into the taper sleeve, as shown in figure 3, and fit washer and tensioning bolt, as shown. Tighten the tensioning bolts one after the other with approx. 0.5 x T A in the first pass (see table 1), if necessary, brace at the screw plug. Tensioning bolt and screw plug must be fitted with "medium firm" thread locking medium (e.g. Loctite 243). Then, in the second pass, tighten to T A (see table 1). After tightening, the end faces of the taper sleeve and taper pin must sit flush (see figure 1) Fig. 3: Detailed view of the taper pin 1 Screw plug 2 Taper surface, greased 3 Tensioning bolt 8 / 14

10 3.3 Axial backlash limitation or vertical support (integrated) When fitting the plate packs with integrated axial backlash limitation or vertical support, the same procedure applies as described in item 3.2. However, the following must be noted additionally: The plate pack must be bolted to the coupling parts so that the respective tie of the star plate of the integrated axial backlash limitation or vertical support is in contact with the ARPEX flange at the point of bolt connection (see figure 4). Only in this fitting position is correct operation of the axial backlash limitation or vertical support guaranteed. If wrongly fitted (tie of the star flange is not fitted as shown in figure 4), the integrated axial backlash limitation or vertical support will not be able to operate properly and will cause coupling damage during operation Fig. 4: Fitting the plate packs with integrated axial backlash limitation or vertical support 1 ARPEX flange 2 Interception ring 3 Washer 4 Star flange 5 Star flange 6 Washer 7 Interception ring 8 ARPEX flange 9 Tie of star flange 10 ARPEX flange 11 Star flange Failure to observe these instructions may result in breakage of the coupling. Danger to life from flying fragments. A damaged coupling becomes an explosion hazard. Operating the coupling with damaged coupling parts is not permitted in potentially explosive environments in accordance with Directive 2014/34/EU. 4. Alignment ARPEX couplings compensate for alignment faults in the shafts to be connected. Couplings with two plate packs support axial, radial and angular misalignment. Couplings with one plate pack support only angular and axial misalignment. 10 / 14

11 When aligning machine parts with a sliding caliper gauge, measure the distance "S 1 " (see figure 5 and table 3) between the coupling flanges at a number of measuring points. If the measured flange distances are within the range of values shown between S 1 min. and S 1 max. (table 3), the machine parts are sufficiently precisely aligned. S 1 max. S 1 min. M M M M M M S 1 min. S 1 max. Fig. 5: Aligning the machine parts S 1 = Distance between coupling flanges S 1 min. = see table 3 S 1 max. = see table 3 M = Measuring point The fitting misalignment must not exceed nor fall below the values for S 1 min. and S 1 max. (table 3). It is however recommended to align the coupling as precisely as possible so as to have an additional margin for misalignment in operation. Impermissible fitting misalignments may cause accelerated wear and damage to the coupling. Failure to observe these instructions may result in breakage of the coupling. Danger to life from flying fragments. A damaged coupling becomes an explosion hazard. Operating the coupling with damaged coupling parts is not permitted in potentially explosive environments in accordance with Directive 2014/34/EU.
