Orbital hydraulic motors
Orbital Hydraulic Motors
Orbital hydraulic motors are a specialized type of hydraulic units that, thanks to their compact design and high efficiency, find applications in a wide range of industrial, agricultural, and construction machinery. A key feature that distinguishes orbital hydraulic motors is their design based on the gerotor mechanism. This mechanism consists of an internal-toothed rotor and an external-toothed stator, allowing smooth transmission of torque at low speeds and high torque output.
What distinguishes orbital hydraulic motors?
Orbital hydraulic motors are characterized by exceptional durability and the ability to operate under demanding conditions. By minimizing the number of moving parts, these devices exhibit high wear resistance and low noise levels. Hydraulic fluid transmits rotational energy, driving the orbital rotor, which moves both around its own axis and eccentrically relative to the stator.
Orbital hydraulic motors — key parameters
Technically, orbital hydraulic motors achieve working pressures ranging from 100 to 250 bar, and their maximum rotational speed can reach up to 1000 rpm, depending on the model. These motors offer precise speed control capabilities and provide a wide range of displacement volumes, from small to medium sizes, depending on application requirements.
Construction of orbital hydraulic motors
An important technical aspect is the design of drive shafts and sealing systems. Orbital hydraulic motors can be equipped with tapered, splined, or cylindrical shafts, enabling integration with various types of gearboxes and devices. Standard seals are made of materials resistant to high temperatures and pressures, increasing the durability of hydraulic systems.
Additionally, orbital hydraulic motors offer several variants of hydraulic connections, such as threaded or flange connections, allowing easy adaptation to existing hydraulic power systems. The compact design enables installation in confined spaces, and the low rotor inertia ensures quick response to load changes. These motors also demonstrate high resistance to axial and radial forces, especially when equipped with tapered bearings.
