The A2FE fastened plug-in motor with axial tapered piston rotary group of bent-axis design, for hydrostatic drives in open and shut circuits
-Considerably-reaching integration in mechanical gearbox owing to recessed mounting flange situated in the center of the situation (incredibly room-saving design)
-The output velocity is dependent on the stream of the pump and the displacement of the motor.
-The output torque will increase with the strain differential amongst the high-pressure and the lower-force facet.
-Modest proportions.
-Large total efficiency.
-Comprehensive unit, prepared-assembled and analyzed.
-Straightforward to set up, basically plug into the mechanical gearbox.
-No configuration requirements to be noticed when putting in.

CZPT fluid
Prior to beginning project plHangCZPT, make sure you refer to our info sheets RE 95710 (mineral oil), RE 95711 (environmentally suitable hydraulic fluids) and RE 95712 (HFD hydraulic fluids) and RE 95713 (HFA, HFB, HFC hydraulic fluids) for comprehensive data concerning the decision of hydraulic fluid and software situations. 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 used, the constraints relating to technical information or other seals should be observed.
Specifics relating to the choice of hydraulic fluid
The appropriate selection of hydraulic fluid calls for information of the operating temperature in relation to the ambient temperature: in a shut circuit, the circuit temperature, in an open circuit, the reservoir temperature. The hydraulic fluid ought to be chosen so that the functioning viscosity in the working temperature range is inside of the optimum selection (νopt), see shaded location of the selection diagram. We advisable that the higher viscosity course be picked in each situation. Case in point: At an ambient temperature of X °C, an functioning temperature of 60 °C is established in the circuit. In the the best possible working viscosity range (νopt., shaded location) this corresponds to the viscosity courses VG 46 or VG 68 to be picked: VG sixty eight.
Notice: The situation drain temperature, which is afflicted by pressure and pace, can be greater than the circuit temperature or reservoir temperature. At no level of the part may possibly the temperature be increased than one hundred fifteen °C. The temperature variation specified underneath is to be taken into account when deciding the viscosity in the bearing. If the over problems are not able to be managed owing to severe working parameters, we advise the use of a flushing and boost stress valve.
Shaft seal
Permissible force loading the support lifestyle of the shaft seal is affected by the velocity of the axial piston unit and the case drain stress (case strain). The suggest differential pressure of two bar in between the situation and the ambient strain could not be enduringly exceeded at standard operating temperature. For a larger differential force at reduced pace, 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.
