2 RE 14 7/3.96 Functional Description, applications, mode of operation, variants Gerotor motors are robust hydraulic driveline elements with universal applications. The Gerotor has a special design feature (Gerotor reduction) that allows low output speeds without the need for additional gear stages. In many cases, this can help to reduce costs and cut down weight. Gerotor motors are self-lubricating and practically maintenance-free, merely requiring a regular oil change. Gerotor motors cover a torque spectrum from 1 danm to 1 danm and operate in a power range from to kw. pplications: gricultural and forestry vehicles Conveyor systems Cranes and transport systems unicipal vehicles (road sweepers, snow clearers, road gritters, etc.) Construction machinery ining equipment Winch drives Plastics machinery Wood processing machinery achine tools Shipbuilding ode of operation: Gerotor motors are internally geared motors that convert hydraulic energy into mechanical energy. The Gerotor consists of a ring with an internal gear profile, and an excentric pinion mounted in this internal ring gear. The pinion has one tooth less than the internal ring gear and so only advances by one tooth space every time it rotates within the ring. This effect gives rise to a reduction ratio, which is the basis for the excellent slow-running characteristics of this motor design. cardan shaft with crowned profile on either end transmits the power from the pinion to the output shaft. Series GP, GR and GVD motors are controlled using the control grooves in a drum valve. This drum valve is a part of the shaft in GP and GR motors, whereas the shaft in the GVD model draws the drum valve with it. otor torque is dependent on the size of motor (cm 3 per revolution) and the pressure differential between the inlet and outlet connections Variants: Gerotormotors offers a wide choice of special versions for particular applications in addition to its comprehensive range of standard motors. Wheel motors with recessed mounting flange Two-stage switching motors with variable intake volumes otors with a speedo connection for measuring speeds otors with integrated shock valves 2/32

31 Direction of shaft rotation (looking at shaft end) RE 14 7/3.96 Direction of shaft rotation (allocation of ports) E = Inlet = Outlet E E Permissible shaft load Permissible shaft load for GVD: The tapered roller bearings on the output shaft mean it can accept high levels of axial and radial shaft load. Radial load starting characteristics are considerably better than motors with plain bearings. The broken curve plots the maximum permissible radial load. Loads above and beyond this level can lead to breakage. The central solid curves plot the permissible radial loads for a theoretical service life (1) of hours at 2 min-1. The expected service life can be calculated for different speeds and / or radial loads. Please refer to the "Gerotormotors Generelles" brochure for more detailed information about the calculation methods. These data assume the use of a hydraulic fluid with a sufficient anti-wear additive content.
