RE 91 604/05.06 6V osch Rexroth 5/76 Technical data Hydraulic fluid efore starting project planning, please refer to our data sheets RE 90220 (mineral oil), RE 90221 (environmentally acceptable hydraulic fluids) and RE 90223 (HF hydraulic fluids) for detailed information regarding the choice of hydraulic fluid and application conditions. The 6V variable motor is unsuitable for operation with HF. If HF, HFC and HFD or environmentally acceptable hydraulic fluids are being used, the limitations regarding technical data and seals mentioned in RE 90221 and RE 90223 must be observed. When ordering, please indicate the used hydraulic fluid. Operating viscosity range For optimum efficiency and service life, select an operating viscosity (at operating temperature) within the optimum range of ν opt = optimum operating viscosity 16 to 36 mm 2 /s depending on the circuit temperature (closed circuit) and tank temperature (open circuit). Viscosity limiting range The following values apply in extreme cases: Sizes 28 to 200: ν min = 5 mm 2 /s, short-term (t < 3 min) at max. permitted temperature of t max = +115 C. ν max = 1600 mm 2 /s, short-term (t < 3 min) on cold start (p < 30 bar, n 1000 rpm, t min = -40 C) Sizes 250 to 1000: ν min = 10 mm 2 /s, short-term (t < 3 min) at max. permitted temperature of t max = +90 C. ν max = 1000 mm 2 /s, short-term (t < 3 min) on cold start (p 30 bar, n 1000 rpm, t min = -25 C). Note that the maximum hydraulic fluid temperature of 115 C must not be exceeded locally either (e.g. in the bearing area). The temperature in the bearing area is - depending on pressure and speed - up to 12 K higher than the average case drain temperature. Special measures are necessary in the temperature range from -25 C and -40 C. Please contact us. For detailed information about use at low temperatures, see RE 90300-03-.

The hydraulic fluid should be chosen so that the operating viscosity in the operating temperature range is within the optimum range (ν opt. ) - the shaded area of the selection diagram. We recommend that the higher viscosity class be selected in each case. Example: t an ambient temperature of C an operating temperature of 60 C is set in the circuit. In the optimum operating viscosity range (ν opt ; shaded area) this corresponds to the viscosity classes V 46 or V 68; to be selected: V 68. Please note: The case drain temperature, which is affected by pressure and speed, is always higher than the circuit temperature or tank temperature. t no point in the system may the temperature be higher than 115 C for sizes 28 to 200 or 90 C for sizes 250 to 1000. If the above conditions cannot be maintained due to extreme operating parameters, we recommend flushing the case at port U or using a flush and boost pressure valve (see pages 66-67). 36 16

RE 91 604/05.06 6V osch Rexroth 9/76 HD - Hydraulic control, pilot-pressure related The pilot-pressure related hydraulic control permits infinite control of the displacement according to the pilot-pressure signal. The displacement is proportional to the pilot pressure applied to port. Standard configuration: Start of control at V g max (max. torque, min. speed) End of control at V g min (min. torque, max. permitted speed) Please note: aximum permissible pilot pressure: 100 bar For reliable control, an operating pressure of at least 30 bar is necessary in (). If a control operation is performed at an operating pressure < 30 bar, an auxiliary pressure of at least 30 bar must be applied at port via an external check valve. Lower pressures may be adequate in individual cases. Please state the desired start of control in plain text when ordering, e.g.: start of control at 10 bar. The following only applies to sizes 250 to 1000: The start of control and the HD characteristic are influenced by the case pressure. n increase in the case pressure causes an increase in the start of control and thus a parallel displacement of the characteristic (see page 6). Fluid escapes from port at the rate of max. 0.3 l/min due to internal leakage (operating pressure > pilot pressure). To prevent a build-up in pilot pressure, port must be vented to tank. HD2 pilot pressure increase Δp S = 25 bar n increase in pilot pressure of 25 bar on port causes a reduction in the displacement from V g max to 0 cm 3 (sizes 28 to 200) or from V g max to 0.2 V g max (sizes 250 to 1000).

22/76 osch Rexroth 6V RE 91 604/05.06 D - Hydraulic control, speed related The 6V variable motor with speed-related hydraulic control is best used for hydrostatic drives in combination with the 4V variable pump with D control. The pilot pressure derived from the drive speed of the 4V variable pump, together with the operating pressure, regulate the swivel angle of the hydraulic motor. Increasing drive speed, i.e. increasing pilot pressure, causes the motor to swivel to a smaller displacement (lower torque, higher speed), depending on the operating pressure. If the operating pressure increase above the pressure setting of the controller, the variable motor swivels to a larger displacement (higher torque, lower speed). The design of a drive with D control must be carried out using the technical data relating to the 4V variable pump with D control. Detailed information can be obtained from our sales departments and on the Internet at www.boschrexroth.com/da-control. Please note: The start of control and the D characteristic are influenced by the case pressure. n increase in the case pressure causes a drop in the start of control and thus a parallel displacement of the characteristic (see page 6).

This impulsive braking is prevented through the use of the following electrical circuit. With this circuit, when the pump (4V, 10V) is switched 1. to the neutral position: the previous travel direction is retained. 2. to reverse: the motor switches to the other travel direction following a time delay (approx. 0.8 s) with respect to the pump.

66/76 osch Rexroth 6V RE 91 604/05.06 Flush and boost pressure valve The flush and boost pressure valve is used to remove heat from the closed circuit and to ensure that a minimum boost pressure is present (opening pressure 16 bar, fixed; note when setting primary valve). side effect is flushing of the case. Warm hydraulic fluid is directed from the respective low pressure side into the motor case. This is then fed into the tank, together with the case drain. The hydraulic fluid drawn out of the closed circuit in this way must be replaced by cooled hydraulic fluid that is supplied by the boost pump. Circuit diagram Sizes 28 to 200 U T 1 2 In an open circuit system, the flush and boost pressure valve is used solely to flush the case from the return line. The valve is fitted to the variable motor (or integrated into the control unit, depending on the type of control and the size).
