Core Product Overview
This product is a hydraulic motor specially designed for heavy-duty hydraulic drive scenarios with limited space, high reliability requirements, and high power density. Its most notable feature is the adoption of a unique four-bolt diamond-shaped flange mounting interface, along with a spline output shaft of 31.75mm (1.25 inches) with 14 teeth and a diametral pitch of 12/24. This design ensures that the motor can achieve extremely compact installation, excellent torsional stiffness, and efficient power transmission under harsh working conditions, making it an ideal power core for driving various types of heavy-duty rotating equipment.
Core Advantages and Features
• ⛓️ Excellent structural rigidity: The four-bolt diamond flange mounting surface provides excellent anti-torsional and anti-bending performance, which can effectively handle heavy loads and impact loads, ensuring the long-term stable operation of the transmission system.
• 🔧 Efficient spline connection: The spline shaft design of 31.75mm 14-DP12/24 achieves greater torque transmission capacity and higher centering accuracy. Compared with ordinary flat key connections, the reliability is significantly improved.
• 📐 Ultimate space saving: The diamond flange design occupies less space than traditional square or round flanges, making it particularly suitable for integrated installation in compact equipment layouts.
• ⚙️ Wide working condition adaptability: High-quality bearings and seals are adopted, and the internal flow channel is optimized to ensure high efficiency and low heat generation within a high pressure and wide speed range.
• 🛡️ Long service life: The core friction pair undergoes special hardening treatment, combined with an optimized hydraulic balance design, resulting in extremely low wear, ensuring an ultra-long service life and low maintenance requirements.
Application fields
• Engineering and construction machinery: drums that drive concrete mixers, small winches, and hydraulically driven wheels.
• Agricultural machinery: serving as the driving unit for the header of combine harvesters and the ground wheels of seeders.
• Industrial automation: driving heavy-duty slewing platforms, indexing tables, mixers, or conveyor rollers.
• Special-purpose vehicles: used in auxiliary operating devices of sanitation vehicles and wreckers.
• Marine and offshore engineering: power sources for deck machinery and winches.
