The A2FE fastened plug-in motor with axial tapered piston rotary team of bent-axis style, for hydrostatic drives in open and closed circuits
-Much-reaching integration in mechanical gearbox thanks to recessed mounting flange situated in the centre of the situation (incredibly area-conserving construction)
-The output velocity is dependent on the flow of the pump and the displacement of the motor.
-The output torque raises with the force differential among the substantial-strain and the lower-strain side.
-Tiny proportions.
-High whole effectiveness.
-Complete unit, all set-assembled and examined.
-Simple to set up, simply plug into the mechanical gearbox.
-No configuration specifications to be noticed when setting up.

CZPT fluid
Before commencing task plHangCZPT, please refer to our data sheets RE 95710 (mineral oil), RE 95711 (environmentally acceptable hydraulic fluids) and RE 95712 (HFD hydraulic fluids) and RE 95713 (HFA, HFB, HFC hydraulic fluids) for comprehensive information relating to the decision of hydraulic fluid and application problems. The plug-in motor A2FE is not ideal for operation with HFA hydraulic fluid. If HFB, HFC or HFD or environmentally suitable hydraulic fluids are employed, the limitations regarding specialized information or other seals must be observed.
Particulars concerning the decision of hydraulic fluid
The correct choice of hydraulic fluid calls for expertise 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 ought to be decided on so that the functioning viscosity in the functioning temperature range is inside the optimum assortment (νopt), see shaded region of the choice diagram. We recommended that the increased viscosity course be selected in every single circumstance. Case in point: At an ambient temperature of X °C, an operating temperature of sixty °C is set in the circuit. In the ideal running viscosity assortment (νopt., shaded area) this corresponds to the viscosity courses VG 46 or VG 68 to be chosen: VG sixty eight.
Note: The case drain temperature, which is impacted by force and speed, can be greater than the circuit temperature or reservoir temperature. At no point of the part could the temperature be greater than 115 °C. The temperature big difference specified beneath is to be taken into account when deciding the viscosity in the bearing. If the over situations can not be maintained thanks to intense working parameters, we advise the use of a flushing and enhance pressure valve.
Shaft seal
Permissible force loading the provider daily life of the shaft seal is affected by the speed of the axial piston unit and the scenario drain strain (scenario pressure). The imply differential force of two bar in between the situation and the ambient force might not be enduringly exceeded at regular functioning temperature. For a higher differential stress at diminished speed, see diagram. Momentary pressure 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.
