0. Transmittable loads These couplings for MC-range are calculated with the following loads: - Average ratio for typical bucket elevator drive: i = 50 - Rotational speed: n1 = 1500rpm - Minimum service factor: Fs = 1,5 - Operating torque: MK2 = MN2 / FS (MN2 = nominal output torque) - Start-up torque: MK2 max = MK2 * 2,5 = MN2 * 1,67 For the weight calculation of the swing base, the following parts are taken under consideration: - Gear unit incl. oil filling (MC3RLSF) - Hydraulic coupling (Voith Turbo) - Coupling guard - 4-pole Siemens IEC motor (gray cast iron housing) - Steel whelded swing base

5. Assembly 5.1 Flange connection screws As shown in the part lists the flange connection screws should be strength class 10.9 and nuts strength class 10. Use the following torques for tightening the flange screws:

Size Torque T [Nm]

M20 580 M24 1000 M30 2000 M36 3550

Table 5.1.1: Torque for flange connection screws 5.2 Shrink connection The coupling half will be mounted on the low speed shaft with an interference fit assembly.

Before mounting process, the shaft end has to be cleaned carefully from dirt and grease. Caused by heat supply, the coupling half has to be expanded up to the oversize according to the chosen fit. Therefore the coupling, including the retaining ring, must be heated up to a size dependent temperature, which is between 200°C and 250°C (see table 5.2.1). Protect the lip sealing with covers from radiant heat during assembly. The simplest way to assemble the coupling to the shaft is in vertical mounting position. After cooling down the counterbores have to be filled with hydraulic oil and closed with a screw plug.

6. Disassembly 6.1 Shrink connection The disassembly of flange couplings with cylindrical interference fit assembly can be done in two different ways. Either with a hydraulic cylinder or with a threaded spindle.

Proceeding: - Opening of the screw plugs and secure enough working space. - Mounting of the counter plate, the hydraulic cylinder or the threaded spindle.

To prevent damage on the shaft or hub it is very important not to dispose the coupling. The parallel mounting of the counter plate to the flange is very important.

- Connection of the hydraulic pump to the hydraulic connection 1 and supply with pressure up to 1600 bar until the oil comes out of the hydraulic connection 2.

- Connection of the hydraulic pump to the hydraulic connection 2. Hydraulic connection1 has to be closed with a screw plug. Increase of pressure until the oil comes out of the hydraulic connection 3.

- Connection of the hydraulic pump to the hydraulic connection 3. Hydraulic connection 2 has to be closed with a screw plug. Increase of the pressure until the oil comes out at the face side in a ring at the whole circumference.

After a pressure duration of about 30 minutes, the hydraulic cylinder can be supplied with pressure. Secure to pull up the coupling quickly.
