Product details
1. Product Overview
 
Rexroth (Bosch Rexroth) is a global leader in drive and control technologies. ItsHZC3 Hydraulic Gearboxis a high-performance gear transmission device designed specifically for industrial hydraulic systems. This product integrates mechanical gear transmission with hydraulic control technology, making it suitable for applications requiring precise speed control, high torque transmission, or complex motion control.
 
2. Core Functions
 
  • Hydraulic Drive and Control: Powers the gearbox via a hydraulic system, enabling stepless speed adjustment, directional control, and power distribution.
 
  • Torque Amplification and Transmission: Amplifies torque from the hydraulic motor through a gear set to drive loads (e.g., winches, conveyors, rotary platforms).
 
  • Speed Regulation: Achieves stepless output speed variation by adjusting hydraulic flow or pressure to meet diverse operational requirements.
 
  • Directional Control: Supports forward/reverse rotation for bidirectional motion.
 
3. Technical Features
 
  • High-Efficiency Transmission: Optimized gear design (e.g., helical or planetary gears) minimizes energy loss and enhances transmission efficiency.
 
  • Compact Structure: Integrated design with a small footprint and lightweight construction, ideal for space-constrained installations.
 
  • Durability: Built with high-strength materials (e.g., alloy steel) and precision machining for reliable performance under heavy loads.
 
  • Superior Sealing: Multi-layer sealing prevents hydraulic oil leakage, ensuring operation in harsh environments (e.g., high temperatures, dust).
 
  • Modular Design: Flexible configuration options, allowing customization with brakes, encoders, cooling systems, and other accessories.
 
4. Applications
 
  • Construction Machinery: Slewing or hoisting systems in cranes, excavators, and concrete pumps.
 
  • Industrial Automation: Robotic joint drives, CNC machine feed systems, and packaging machinery.
 
  • Energy & Mining: Wind turbine yaw systems, mine hoists, and conveyor equipment.
 
  • Marine & Offshore Engineering: Steering gear systems, deck machinery, and drilling platform equipment.
 
  • Agricultural Machinery: Hydraulic transmission systems in combine harvesters and tractors.
 
5. Advantages
 
  • Precision Control: Fast hydraulic response enables micron-level positioning or millisecond-level speed switching.
 
  • Overload Protection: Built-in safety valves or torque limiters prevent equipment damage from excessive loads.
 
  • Low-Noise Operation: Optimized gear meshing and hydraulic circuit design reduce vibration and noise.
 
  • Easy Maintenance: Modular structure simplifies disassembly, with quick replacement of critical components (e.g., bearings, seals).
 
  • Strong Compatibility: Seamless integration with other Rexroth hydraulic components (e.g., pumps, valves, motors) for complete system solutions.
 
6. Selection & Specifications
 
  • Input Parameters: Hydraulic motor interface type, pressure range, and flow requirements.
 
  • Output Parameters: Torque, speed, gear ratio, and output shaft type (e.g., spline, keyway).
 
  • Environmental Adaptability: Operating temperature range, protection rating (e.g., IP65), and shock resistance.
 
  • Certifications: Compliance with international standards (ISO, DIN, CE), with ATEX explosion-proof certification available for select models.
 
7. Typical Use Cases
 
  • Crane Slewing Systems: Drives rotary mechanisms for 360° precise rotation.
 
  • Wind Turbine Yaw Drives: Adjusts blade orientation via hydraulic control to optimize power generation.
 
  • Automated Production Lines: Powers conveyors or rotary workstations for material sorting and positioning.
 
8. Maintenance & Upkeep
 
  • Regular Inspections: Monitor hydraulic oil cleanliness, gearbox temperature, and seal condition.
 
  • Lubrication Management: Replace hydraulic and gear oils at recommended intervals to prevent wear.
 
  • Fault Diagnosis: Use pressure sensors or vibration analysis to detect anomalies and prevent failures.
