The A2FE mounted plug-in motor with axial tapered piston rotary group of bent-axis style, for hydrostatic drives in open and closed circuits
-Considerably-reaching integration in mechanical gearbox due to recessed mounting flange positioned in the centre of the case (incredibly space-saving building)
-The output velocity is dependent on the circulation of the pump and the displacement of the motor.
-The output torque will increase with the force differential between the high-strain and the reduced-strain aspect.
-Higher overall effectiveness.
-CZPT device, completely ready-assembled and examined.
-Straightforward to put in, simply plug into the mechanical gearbox.
-No configuration specifications to be observed when putting in.

Before commencing project plHangZhou, remember to refer to our info sheets RE 95710 (mineral oil), RE 95711 (environmentally satisfactory hydraulic fluids) and RE 95712 (HFD hydraulic fluids) and RE 95713 (HFA, HFB, HFC hydraulic fluids) for thorough info relating to the option of hydraulic fluid and software circumstances. The plug-in motor A2FE is not ideal for procedure with HFA hydraulic fluid. If HFB, HFC or HFD or environmentally appropriate hydraulic fluids are employed, the constraints relating to complex knowledge or other seals need to be noticed.
Details relating to the selection of hydraulic fluid
The proper choice of hydraulic fluid calls for understanding of the working temperature in relation to the ambient temperature: in a closed circuit, the circuit temperature, in an open circuit, the reservoir temperature. The hydraulic fluid need to be decided on so that the working viscosity in the operating temperature range is in the ideal selection (νopt), see shaded region of the choice diagram. We advisable that the higher viscosity course be selected in each and every scenario. Illustration: At an ambient temperature of X °C, an running temperature of 60 °C is established in the circuit. In the the best possible operating viscosity variety (νopt., shaded location) this corresponds to the viscosity lessons VG 46 or VG 68 to be selected: VG 68.
Be aware: The circumstance drain temperature, which is influenced by stress and speed, can be larger than the circuit temperature or reservoir temperature. At no point of the ingredient may possibly the temperature be larger than a hundred and fifteen °C. The temperature difference specified underneath is to be taken into account when determining the viscosity in the bearing. If the over circumstances are not able to be preserved owing to excessive working parameters, we suggest the use of a flushing and boost strain valve.
Permissible stress loading the support existence of the shaft seal is affected by the pace of the axial piston unit and the circumstance drain force (case pressure). The mean differential pressure of two bar in between the circumstance and the ambient stress could not be enduringly exceeded at regular functioning temperature. For a higher differential stress at lowered velocity, see diagram. Momentary force spikes (t < 0.1 s) of up to 10 bar are permitted. The service life of the shaft seal decreases with an increase in the frequency of pressure spikes.
