The A2FE set plug-in motor with axial tapered piston rotary team of bent-axis design and style, for hydrostatic drives in open up and shut circuits
-Far-achieving integration in mechanical gearbox thanks to recessed mounting flange situated in the center of the circumstance (extremely room-preserving construction)
-The output pace is dependent on the movement of the pump and the displacement of the motor.
-The output torque will increase with the force differential amongst the higher-pressure and the reduced-pressure facet.
-Small dimensions.
-Higher overall effectiveness.
-CZPT device, prepared-assembled and analyzed.
-Straightforward to install, merely plug into the mechanical gearbox.
-No configuration technical specs to be observed when installing.

CZPT fluid
Before beginning undertaking plHangZhou, you should refer to our knowledge 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 detailed data concerning the option of hydraulic fluid and application conditions. The plug-in motor A2FE is not ideal for procedure with HFA hydraulic fluid. If HFB, HFC or HFD or environmentally satisfactory hydraulic fluids are utilised, the limitations relating to technological information or other seals must be noticed.
Information regarding the selection of hydraulic fluid
The right selection of hydraulic fluid requires understanding of the working temperature in relation to the ambient temperature: in a shut 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 working temperature variety is inside of the the best possible selection (νopt), see shaded spot of the choice diagram. We recommended that the higher viscosity class be selected in each circumstance. Illustration: At an ambient temperature of X °C, an functioning temperature of 60 °C is established in the circuit. In the optimum running viscosity selection (νopt., shaded area) this corresponds to the viscosity courses VG 46 or VG sixty eight to be selected: VG 68.
Observe: The scenario drain temperature, which is influenced by pressure and speed, can be higher than the circuit temperature or reservoir temperature. At no point of the element could the temperature be greater than one hundred fifteen °C. The temperature difference specified underneath is to be taken into account when deciding the viscosity in the bearing. If the above circumstances can’t be preserved because of to extreme functioning parameters, we advise the use of a flushing and boost strain valve.
Shaft seal
Permissible pressure loading the service life of the shaft seal is affected by the speed of the axial piston device and the case drain stress (circumstance stress). The mean differential pressure of 2 bar in between the circumstance and the ambient stress might not be enduringly exceeded at typical operating temperature. For a larger differential force at reduced velocity, 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.
