The A2FE mounted plug-in motor with axial tapered piston rotary team of bent-axis design, for hydrostatic drives in open up and shut circuits
-Significantly-reaching integration in mechanical gearbox due to recessed mounting flange situated in the heart of the situation (really area-conserving design)
-The output pace is dependent on the stream of the pump and the displacement of the motor.
-The output torque boosts with the stress differential between the substantial-stress and the lower-force facet.
-Small dimensions.
-High complete efficiency.
-CZPT unit, ready-assembled and tested.
-Effortless to put in, just plug into the mechanical gearbox.
-No configuration requirements to be observed when putting in.

CZPT fluid
Prior to starting venture plHangZhou, make sure you refer to our information sheets RE 95710 (mineral oil), RE 95711 (environmentally appropriate hydraulic fluids) and RE 95712 (HFD hydraulic fluids) and RE 95713 (HFA, HFB, HFC hydraulic fluids) for thorough data with regards to the choice of hydraulic fluid and software circumstances. The plug-in motor A2FE is not suitable for procedure with HFA hydraulic fluid. If HFB, HFC or HFD or environmentally suitable hydraulic fluids are used, the restrictions relating to specialized information or other seals need to be observed.
Information with regards to the choice of hydraulic fluid
The correct selection of hydraulic fluid calls for information of the functioning temperature in relation to the ambient temperature: in a closed circuit, the circuit temperature, in an open up circuit, the reservoir temperature. The hydraulic fluid should be decided on so that the working viscosity in the operating temperature range is in the the best possible variety (νopt), see shaded region of the selection diagram. We advised that the increased viscosity class be selected in every single scenario. Illustration: At an ambient temperature of X °C, an running temperature of sixty °C is established in the circuit. In the ideal running viscosity range (νopt., shaded area) this corresponds to the viscosity courses VG 46 or VG 68 to be chosen: VG sixty eight.
Note: The situation drain temperature, which is affected by force and velocity, can be increased than the circuit temperature or reservoir temperature. At no point of the component could the temperature be larger than one hundred fifteen °C. The temperature variation specified below is to be taken into account when figuring out the viscosity in the bearing. If the over circumstances can’t be maintained thanks to severe running parameters, we advocate the use of a flushing and increase pressure valve.
Shaft seal
Permissible pressure loading the provider existence of the shaft seal is motivated by the speed of the axial piston device and the scenario drain stress (scenario stress). The imply differential stress of two bar between the circumstance and the ambient stress may possibly not be enduringly exceeded at regular running temperature. For a higher differential force at reduced pace, see diagram. Momentary strain 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.
