Product Overview
151B3100 is a high-performance gerotor hydraulic motor from Danfoss' OMV series, corresponding to the model code OMV-0315-A-NN-G34-AE-1E-A35-A-A-1B-1-N-NN-NNNNN-NN-NN-NN-SP-NNN. This model has a displacement of 315 cm³/rev and adopts advanced disc valve distribution and Geroler® roller stator-rotor technology. It is equipped with a 50mm cylindrical output shaft, a 4-bolt square mounting flange, and G1/G1/4 standard side oil ports. As a medium and large displacement model in the OMV series, it is specially designed for medium and heavy-duty industrial and mobile hydraulic applications that require high torque, high efficiency, and high reliability.
Core Features
1. Advanced Geroler® roller stator-rotor technology
- High starting torque: Adopts a inlaid column type stator-rotor pair design, featuring low starting pressure and high starting efficiency, ensuring smooth startup under heavy loads.
- Excellent low-speed stability: Can operate stably at extremely low speeds, meeting the requirements for precise control and uniform feeding.
- High efficiency retention: Advanced stator-rotor parameter design enables the whole machine to maintain high efficiency throughout its service life.
2. Disc-type distribution system
- Automatic wear compensation: Adopts an end face distribution disc structure with high distribution accuracy, which automatically compensates after wear, ensuring long-term maintenance of high volumetric efficiency and long service life.
- Pressure balance design: The two sealing end faces of the distribution disc maintain pressure balance, minimizing internal leakage and improving overall efficiency.
- High-pressure shaft seal design: Can withstand high return oil pressure without a separate oil drain pipeline, simplifying the hydraulic system layout.
3. Robust load-bearing structure
- Tapered roller bearing support: Both front and rear ends use heavy-duty tapered roller bearings, which can bear high radial and axial loads and adapt to impact load conditions.
- High-strength cast iron housing: A sturdy shell design that can withstand harsh operating environments.
Application fields
