The Popular Rexroth A6ve Series Hydraulic Piston Motor

The well-known CZPT A6ve series CZPT Piston Motor  

Brueninghaus Hydromatik CZPT A6VE motor
 
CZPT variable motor A6VE28, A6VE55, A6VE80, A6VE107, A6VE160, A6VE250

Description  

Open up and closed circuits
Collection sixty three
Size 28 to 160 nominal stress 400 bars and optimum strain 450 bar.
Dimension 250 nominal force 350 bars and maximum pressure four hundred bar.
 
-Variable plug-in motor with axial tapered piston rotary group of bent-axis style, for hydrostatic drives in open and shut circuits
-Significantly-achieving integration in mechanical gearbox due to a recessed mounting flange positioned on the middle of the situation (really room-saving building)
-Simple to install, merely plug into the mechanical gearbox (no configuration technical specs to be observed)
-Tested unit completely ready to install
-For use particularly in cellular programs
-The displacement can be infinitely transformed from Vg max to Vg min = .
-The wide manage selection enables the variable motor to fulfill the necessity for higher speed and higher torque.
-The output speed is dependent on the stream of the pump and the displacement of the motor.
-The output torque raises with the stress differential between the substantial-force and low-strain facet and with escalating displacement.

CZPT fluid
Ahead of beginning task plHangCZPT, please refer to our knowledge sheets RE 95710 (mineral oil), RE 95711 (environmentally satisfactory hydraulic fluids) and RE 95713 (HF hydraulic fluids) for comprehensive information regarding the choice of hydraulic fluids and conditions of use. The A6VE variable displacement plug-in motor is not suited for use with HFA. If HFB, HFC and HFD or environmentally satisfactory hydraulic fluids are being utilised, the constraints regarding specialized data and seals pointed out in RE 95711 and RE 95713 have to be noticed. If needed, you should make contact with us to go over.
Viscosity selection  
We advocate that a viscosity (at functioning temperature) for ideal performance and support existence needs of νopt = optimum viscosity sixteen to 36 mm2/s be selected, taken the circulation temperature (shut circuit) and reservoir temperature (open up circuit) into account.
Restrictions of viscosity assortment. The subsequent values implement in severe circumstances:
νmin = five mm2/s
Quick-expression (t < 3 min) at max. permitted temperature of tmax = +115°C. νmax = 1600mm2/s.
Quick-time period (t < 3 min) with cold start (p < 30 bar, n ≤ 1000 rpm, tmin = -40°C).
Note that the highest hydraulic fluid temperature have to not be exceeded regionally possibly (e.g. for the duration of storage). The temperature in the bearing region is – depending on strain and velocity – up to twelve k higher than the typical situation drain temperature.
CZPT measures are needed at temperatures in between -25°C and -40°C. Remember to make contact with us.
Shaft seal ring
The services daily life of the shaft seal ring is impacted by the pace of the motor and the circumstance drain strain. The permitted loading with intermittent case drain stress is dependent on the rotational speed (see chart). Brief-phrase (t < 5 s) pressure spikes of up to 6 bar absolute are permitted.
The typical long term scenario drain force must not exceed 3 bar complete. The stress in the situation must be equal to or greater than the exterior strain on the shaft seal ring.
Flushing and Increase Force Valve 
The flushing and boost stress valve is utilised to remove heat from the closed circuit and to ensure that a minimum cost force is existing (opening stress 16 bar, fastened be aware when setting main valve). A aspect effect is flushing of the circumstance.
Heat pressure fluid is taken off from the appropriate minimal pressure facet into the motor case. This is then fed into the reservoir, collectively with the leakage fluid. The stress fluid drawn out of the shut circuit in this way has to be replaced by cooled oil that is pumped in by the cost pump. In the open up circuit, the flushing and boost strain valve is utilized exclusively to flush the situation from the return line.
The valve is equipped to the variable displacement motor (or built-in into the servo device, based on the kind of handle and the dimension).
