2 month ago
Product details
1. Product Overview
TheIAM600H3is a high-torqueexternal five-star hydraulic motordesigned forhigh-load, low-speed, high-torque applications, featuring a five-gear meshing system (five-star gear train). Driven by hydraulic oil, it delivers rotational motion with the following core advantages:
• High torque density: Significantly higher torque output per unit volume compared to conventional gear motors.
• Low-speed stability: Smooth operation across 10–500 RPM, ideal for injection molding machine clamping and boring machine spindle drives.
• Strong shock resistance: Five-star gear train distributes loads evenly, withstanding frequent starts/stops and overload conditions.
• Long service life: High-strength alloy gears and wear-resistant bearings ensure ≥10,000 hours of design life.
2. Technical Specifications
【表格】
Parameter IAM600H3 Typical Value Explanation
Displacement 600 cm³/rev Theoretical torque output depends on displacement (Torque = Displacement × Pressure / 2π).
Rated Pressure 25 MPa (250 bar) Maximum continuous operating pressure; exceeding may cause seal failure.
Peak Pressure 30 MPa (300 bar) Short-term (<10 sec) maximum pressure for startup or overload.
Rated Torque 2,387 N·m (@25 MPa) Calculation: 600 cm³/rev × 25 MPa / (2π × 100) ≈ 2,387 N·m.
Peak Torque 2,865 N·m (@30 MPa) Transient overload capacity for injection molding machine clamping shocks.
Speed Range 10–500 RPM Torque fluctuation <±3% in low-speed range; efficiency declines at high speeds.
Efficiency 85%–90% (mechanical + volumetric) Typical hydraulic motor efficiency, influenced by pressure and speed.
Weight 45–55 kg (depending on configuration) Includes shaft, flange, and ports.
IP Rating IP65 Dust- and water-resistant for industrial environments.
3. Structural Features
• Five-Star Gear Train Design:
• Comprises 1 sun gear (driver) and 4 planet gears (driven), with more meshing points for even load distribution.
• Reduces torque fluctuation by 40% and extends lifespan by 30% compared to traditional dual-gear motors.
• High-Pressure Sealing System:
• Dual-lip shaft seals + O-rings withstand 30 MPa; leakage <5 mL/min.
• Cast iron housing (HT250) with nickel plating for corrosion resistance.
• Modular Interfaces:
• Output shaft: Supports keyway, spline, or flange connections for injection molding/boring machine spindles.
• Ports: SAE or BSPT threads; optional pressure compensation valves.
4. Application Scenarios
(1) Injection Molding Machine Clamping System
• Function: Drives the clamping mechanism (platen, tie bars) for mold opening/closing.
• Advantages:
• Low-speed, high-torque: Slow clamping (50–200 RPM) with 2,387 N·m torque ensures stable locking force.
• Shock resistance: Peak torque of 2,865 N·m prevents motor stalling during mold opening.
• Energy efficiency: 10%–15% higher efficiency than motor + gearbox systems.
(2) Boring Machine Spindle Drive
• Function: Drives boring tools for hole machining (rough/finish boring).
• Advantages:
• Constant torque output: Torque fluctuation <±3% across 10–500 RPM ensures machining precision.
• Overload protection: Peak torque absorbs shocks from hard spots or tool breakage.
• Compact design: Five-star gear train reduces length by 20% vs. conventional motors.
(3) Other Heavy-Duty Applications
• Die-casting machines: Drives injection cylinders for high-speed metal filling.
• Mixing equipment: Drives large agitators for high-viscosity materials.
• Marine steering gears: Low-speed, high-torque drive for rudder blades (custom corrosion-resistant versions available).
5. Selection and Matching Guidelines
(2) System Pressure Matching
• Hydraulic system pressure must ≥ motor rated pressure (25 MPa) with margin (28–30 MPa recommended).
• Pump flow calculation:Q=Displacement×Speed/1000 Q = \text{Displacement} \times \text{Speed} / 1000 Q=Displacement×Speed/1000(L/min).
Example: IAM600H3 at 200 RPM →Q=600×200/1000=120 L/min Q = 600 \times 200 / 1000 = 120 \, \text{L/min} Q=600×200/1000=120L/min.
(3) Installation and Maintenance
• Alignment: Shaft-to-load alignment tolerance ≤ 0.05 mm to avoid vibration.
• Oil Cleanliness: NAS 1638 Class 7 or ISO 4406 18/16 to prevent gear wear.
• Routine Checks: Replace hydraulic oil every 500 hours; inspect seals for leakage.
