• Series: BMV
• Product Type: Cycloid Hydraulic Motor (low speed, high torque, heavy-duty, end face distribution)
• Application: Heavy-duty and medium-heavy duty working conditions such as construction machinery, mining equipment, metallurgical machinery, agricultural machinery, marine winches, airport and port equipment, and medium to large-scale hydraulic transmission systems
• Certification: CE, ISO9001 Certified (in line with international safety and quality standards)

Motor Parameters

• Displacement: 315-1000 cc/rev (reference range, subject to specific model, covering common models such as BMV 315, 400, 500, 630, 800, 1000)
• Rated Working Pressure: 16 MPa (common level for BMV series), maximum working pressure up to 24 MPa (intermittent pressure), peak pressure up to 28 MPa
• Rated Speed: 15-500 rpm (low-speed high-torque characteristic, no-load speed reference value; continuous speed ranges from 200-510 rpm depending on displacement)
• Rated Torque: 900-2200 N·m (varies with displacement and working pressure, continuous torque up to 2015 N·m, peak torque up to 2470 N·m for high-displacement models)
• Volumetric Efficiency: ≥92% (high volumetric efficiency ensured by advanced end face distribution design, which can automatically compensate for wear)
• Mechanical Efficiency: ≥90% (optimized structural design with tapered roller bearings, low energy consumption during heavy-duty operation)

Cycloid Mechanism Parameters

• Cycloid Type: Internal Meshing Cycloid Gear with end face distribution (high torque transmission, compact structure, high distribution precision, automatic wear compensation)
• Number of Teeth: Cycloid Gear 8-14 Teeth, Internal Gear 9-15 Teeth (optimized stator and rotor parameters, low starting pressure, stable meshing transmission)
• Backlash: ≤5 arcmin (high transmission precision, low vibration during heavy-duty operation, ensuring stable load speed characteristics)
• Transmission Ratio: 5:1 – 60:1 (multiple options to adapt to different speed and torque requirements of heavy-duty working conditions)

Structural & Material Specifications

• Housing Material: High-strength Cast Iron (wear-resistant, impact-resistant, suitable for heavy-duty scenarios, adapting to harsh working environments such as mining and construction)
• Gear Material: 20CrMnTi Alloy Steel (carburizing and quenching treatment, tooth surface hardness HRC58-62, strong wear resistance, prolonged service life for heavy-duty operation)
• Seal Type: Double Shaft Seal, FKM (Fluororubber) Seal (high temperature and corrosion resistance, preventing hydraulic oil leakage, ensuring stable operation in harsh industrial environments)
• Bearing: Tapered Roller Bearing (enhances axial and radial load capacity, allowing the motor to directly drive working mechanisms, extending service life)
• Mounting Type: Flange Mounting / Foot Mounting (compatible with various mechanical installation requirements, suitable for different heavy-duty application scenarios)

Environmental & Protection Specifications

• Protection Class: IP55 (dust-proof and water-proof, adaptable to harsh industrial, mining, construction and agricultural environments)
• Working Temperature Range: -20℃ to +100℃ (with FPM seal, suitable for high-temperature working scenarios in heavy-duty operations)
• Storage Temperature Range: -40℃ to +120℃
• Noise Level: ≤70 dB(A) (no-load, due to optimized cycloid meshing design, precision processing and tapered roller bearing structure)
• Viscosity Requirement: 20-460 cSt (40℃, compatible with ISO VG46 anti-wear hydraulic oil, adapting to common hydraulic system requirements for heavy-duty machinery)
