Technical description Observe the instructions in section 3, "Safety instructions"! General description The gear unit described is a planetary gear unit developed for use in bucketwheel excavators. The bucketwheel drive is delivered as a complete drive unit assembled from various components. Fig.
Construction and method of operation Standard mounting position in operation: Longitudinal angle (low or high position) to ± 15°, constant transverse angle 10°. To ensure adequate lubrication here, a motor pump is normally required. For the current fitting position and maximum inclined positions, see the dimensioned drawing. 5.2.1 Bevelhelical planetary gear unit The bevelhelical planetary gear unit essentially comprises a planet stage, two helical gear stages, a bevel...
5.2.1.6 Cooling The gear unit is cooled by heat radiation from the housing. The surface of the housing, which is enlarged by numerous ribs, is especially designed to radiate heat in this way. 5.2.2 Brake For operation, the specific operating instructions must be observed. 5.2.3 Shrink disk For the planetary gear unit a shrink disk should be used as a frictional clamping connection between the...
5.2.7.2 Starting when the bucket wheel is at a standstill The bucket wheel must have reached equilibrium. • Release brake. • Start pump. • After 10 minutes start main motor and/or auxiliary motor. 5.2.7.3 Changeover from main to auxiliary drive •...
5.2.9 Clutch With this drive combination with integrated auxiliary drive the systemspecific requirements set out in section 3, “Safety Notes”, must be observed in all cases! Changeover must be carried out only when the main and auxiliary gear units are at a standstill.
Fitting Observe the instructions in section 3, "Safety instructions"! General information on fitting When transporting the gear unit observe the notes in section 4. Fitting work must be done with great care by authorised, trained and qualified personnel. The manufacturer cannot be held liable for damage caused by incorrect assembly and installation.
The products supplied are listed in the despatch papers. Check immediately on receipt to ensure that all the products listed have actually been delivered. Parts damaged and/or missing parts must be reported to Siemens in writing immediately. The packaging must not be opened or damaged, when this is part of the preservation method! •...
Shrink disk, mechanical version 6.5.1 Fitting the shrink disk • Before beginning installation, the hollow shaft and the stub shaft must be carefully cleaned. Observe manufacturer’s instructions for handling lubricants and solvents. Do not allow cleansing agent or solvent to affect surfaces with paint coating. The bore of the hollow shaft and the stub shaft must be absolutely clean, free of grease and oil in the area of the shrink disk seat.
Page 27
M 16 M 33 2650 The shrink disk has been identitymarked on the outer ring (4). In case of contacting Siemens this identification must be referred to. For safety reasons, a protective cover should be mounted to prevent contact! This cover must be applied after completion of all works on the shrink disk.
6.5.2 Demounting the shrink disk • Remove the protective cover. • Remove any rust deposits from the shaft and the hollow shaft. Under no circumstances must the tensioning bolts be unscrewed one after the other. • Undo all tensioning bolts one after the other by approx. 1/4 turn. The stored energy of the outer ring is slowly loosened during disassembly via the bolts to be loosened.

The maximum permissible clamping pressure is 450 bar! This allows the clamping condition to be checked visually. If alignment cannot be achieved by clamping, consult Siemens. • Turn lock nut fingertight against the outer ring. •...
6.6.2 Demounting the type HYD shrink disk • Remove the protective cover. • Remove screw plugs from the "Clamp" and "Release" connections. Collect any hydraulic fluid that may run out! • Connect the oil pressure pump to the connection marked "Clamp". •...
Fitting of the brake and the couplings 6.9.1 Fitting the brake When fitting the brake, the specific operating instructions for the brake must be observed. 6.9.2 Fitting the couplings When installing the couplings, the specific operating instructions for the couplings must be observed.
6.11 Final work • After installation of the gear unit check all screw connections for tight fit. • Check the alignment after tightening the fastening elements (the alignment must not have been changed). • Check that all the devices which have been demounted for transport reasons have been refitted. ─...
6.12.2 Tightening torques and initial-tensioning forces The tightening torques apply to friction coefficients of μ = 0.14. The friction total coefficient μ = 0.14 applies here to lightly oiled steel bolts, blackannealed or phospatised total and dry, cut mating threads in steel or cast iron. Lubricants which alter the friction coefficient must not be used and may overload the screw connection.

Startup Observe the instructions in section 3, "Safety instructions"! Procedure before startup 7.1.1 Removal of preservative agent • Unscrew and open oil drain plug and drain remaining preservative agent or runningin oil from the housing into a suitable container and dispose of in accordance with regulations. Any residualoil drain plugs should also be opened.
The quality of the oil used must meet the requirements of the separately enclosed BA 7300 operating instructions, otherwise the guarantee given by Siemens will lapse. We urgently recommend using one of the oils listed in BA 7300, because they have been tested and meet the requirements.
Removal from service • Switch off drive unit. Secure the drive unit to prevent it from being started up unintentionally. Attach a warning notice to the start switch. • With gear units fitted with water oilcoolers, close the stop valves on the water in and outflow pipes. To prevent freezing, drain the water from the cooling coil or the water oilcooler.
7.4.2 Exterior preservation 7.4.2.1 Exteriorpreservation procedure • Clean the surfaces. For separation between the sealing lip of the shaftsealing ring and the preservative agent, the shaft should be brushed with grease in way of the sealing lip. • Apply preservative agent. For preservative agent see table 5 in item 4.4.2! Operation Observe the instructions in section 3, "Safety instructions", in section 9, "Faults, causes and remedy", and...
Check • During operation the gear unit must be monitored for: ─ Oil temperature (The gear unit is designed for a temperature of 90 °C with mineral oil in continuous operation. For higher temperatures, synthetic oils must be used. Shortterm operating temperature of up to 100 °C is permitted; see also section 10.) ─...
8.4.2 Starting with auxiliary drive I. 1. Main motor OFF. Secure motor against accidental starting up. I. 2. Blocking brake ON. I. 3. Release locking plate. I. 4. Move shift lever into "ON" position. If the lever cannot be moved into the correct position, proceed as described in section II .1.
Siemens will not be bound by the terms of the guarantee or otherwise be responsible in cases of improper use of the gear unit, modifications carried out without the agreement of Siemens or use of spare parts not supplied by Siemens.

If there is a change to another oil grade or make, Siemens recommends flushing out the gear unit with the new grade of service oil. When changing the oil, the housing and the oilsupply system, if available, must be flushed with oil to remove sludge, metal particles and oil residue.
10.2.3 Cleaning the air filter If a layer of dust has built up, the air filter must be cleaned, whether or not the minimum period of 3 months has expired. • Unscrew the air filter including the reducing screw. • Clean the air filter using benzine or a similar cleanser.
Damaged bolts must be replaced with new bolts of the same type and strength class. 10.3.1 General inspection of the gear unit The general inspection of the gear unit should be carried out by the Siemens Customer Service, as our engineers have the experience and training necessary to identify any components requiring replacement.
