The A2FE set plug-in motor with axial tapered piston rotary team of bent-axis style, for hydrostatic drives in open up and closed circuits
-Far-reaching integration in mechanical gearbox owing to recessed mounting flange positioned in the heart of the case (really room-saving building)
-The output speed is dependent on the flow of the pump and the displacement of the motor.
-The output torque boosts with the pressure differential between the high-stress and the reduced-strain facet.
-Small proportions.
-Large complete performance.
-Full unit, completely ready-assembled and analyzed.
-Effortless to put in, merely plug into the mechanical gearbox.
-No configuration specs to be noticed when setting up.

CZPT fluid
Just before beginning undertaking plHangCZPT, remember to refer to our knowledge 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 in depth data regarding the decision of hydraulic fluid and application situations. The plug-in motor A2FE is not ideal for procedure with HFA hydraulic fluid. If HFB, HFC or HFD or environmentally acceptable hydraulic fluids are used, the limitations relating to technical information or other seals need to be observed.
Details concerning the choice of hydraulic fluid
The proper choice of hydraulic fluid demands information of the operating 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 selected so that the operating viscosity in the working temperature range is inside the optimum range (νopt), see shaded region of the variety diagram. We recommended that the larger viscosity course be picked in each and every situation. Example: At an ambient temperature of X °C, an operating temperature of sixty °C is set in the circuit. In the the best possible running viscosity assortment (νopt., shaded spot) this corresponds to the viscosity lessons VG 46 or VG 68 to be chosen: VG sixty eight.
Be aware: The case drain temperature, which is impacted by pressure and pace, can be higher than the circuit temperature or reservoir temperature. At no stage of the ingredient may possibly the temperature be larger than 115 °C. The temperature distinction specified beneath is to be taken into account when figuring out the viscosity in the bearing. If the earlier mentioned problems can not be maintained due to intense operating parameters, we advise the use of a flushing and improve force valve.
Shaft seal
Permissible force loading the support daily life of the shaft seal is motivated by the pace of the axial piston device and the circumstance drain stress (circumstance strain). The suggest differential force of 2 bar amongst the situation and the ambient stress might not be enduringly exceeded at typical functioning temperature. For a greater differential force at reduced speed, 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.
