1 rueninghaus Hydromatik Series 6, for open and closed circuits xial tapered piston, bent axis design Size Nom. pressure up to 400 bar Peak pressure up to 40 bar RE 9606/0.97 RE 9606/0.97 replaces 08.9 he variable displacement plug-in motor 6VE is equipped with a standard axial tapered piston rotary group of bent axis design. Hydrostatic plug-in motors are intended primarily for installation in mechanical gearboxes, e.g. track drive gear boxes. he design of the motor with the mounting flange in the centre of the housing allows it to be almost fully integrated into a mechanical gearbox to give an extremely compact unit. complete unit, ready assembled and tested easy assembly, simply «plugs-in» to mechanical gearboxes no instalation tolerances to consider

3 RE 9606/0.97 Fluid We request that before starting a project detailed information about the choice of pressure fluids and application conditions are taken from our catalogue sheets RE (mineral oil, RE 9022 (environmentally acceptable hydraulic fluids and RE 9022 (fire resistance fluids, HF. When using HF- or environmentally acceptable hydraulic fluids possible limitations for the technical data have to be taken into consideration. If necessary please consult our technical department (please indicate type of the hydraulic fluid used for your application on the order sheet. he operation with HF-, HF- and HFC- hydraulic fluids requires additional special measures. Operating viscosity range In order to obtain optimum efficiency and service life, we recommend that the operating viscosity (at operating temperature be selected from within the range: ν opt = operating viscosity mm 2 /s referred to the loop temperature (closed circuit or tank temperature (open circuit. Viscosity limits he limiting values for viscosity are as follows: size ν min = mm 2 /s, short term at a max. permissible temperature of t max = C ν max = 600 mm 2 /s, short term on cold start (t min = -40 C size 20 ν min = 0 mm 2 /s short term at a max. permissible leakage oil temp. of t max = 90 C ν max = 000 mm 2 /s, short term on cold start (t min = -2 C In general the max. temperature is the leakage oil temperature of the hydraulic motor in case of hydrostatic transmissions. Please note that the max. fluid temperature is also not exceeded in certain areas (for instance bearing area. t temperatures of -2 C up to -40 C special measures may be required for certain installation positions. Please contact us for further information. Selection diagram viscosity ν (mm 2 /s t min = -40 C VG 22 VG 2 VG 68 VG 46 VG 00 fluid temperature range 600 Notes on the selection of the hydraulic fluid In order to select the correct fluid, it is necessary to know the operating temperature in the loop (closed circuit or the tank temperature (open circuit in relation to the ambient temperature. ν opt temperature t ( C 6 6 t max = + C he hydraulic fluid should be selected so that within the operating temperature range, the operating viscosity lies within the optimum range (ν opt (see shaded section of the selection diagram. We recommend that the highest possible viscosity range should be chosen in each case. Example: t an ambient temperature of X C the operating temperature is 60 C. Within the operating viscosity range (ν opt ; shaded area, this corresponds to viscosity ranges VG 46 or VG 68. VG 68 should be selected. Important: he leakage oil (case drain oil temperature is influenced by pressure and pump speed and is always higher than the circuit temperature. However, at no point in the circuit may the temperature exceed C (90 C, size 20. If it is not possible to comply with the above conditions because of extreme operating parameters or high ambient temperatures please consult us. Filtration he finer the filtration the better the achieved purity grade of the pressure fluid and the longer the life of the axial piston unit. o ensure the functioning of the axial piston unit a minimum purity grade of: 9 to NS 68 6 to SE 8/ to ISO/DIS 4406 is necessary. his is achievable (for example with a filter element type...d (RE 278. t very high temperatures of the hydraulic fluid (90 C to max.
