The ZD, ZDH, and ZDSH series are single-stage, two-stage, and three-stage external engagement involute cylindrical gear reducers, respectively. These series are traditional and highly versatile reducers, renowned for their rugged construction, high efficiency, and reliability. They are suitable for installation in applications requiring a significant center distance between the prime mover (e.g., motor) and the working machine.
1. High Load Capacity: Utilizes hard-tooth surface gears (e.g., carburized, quenched, and ground), offering high strength and the ability to withstand heavy loads and impact loads.
2. High Efficiency: Single-stage transmission efficiency can reach over 98%, resulting in excellent energy savings.
3. Long Service Life: Excellent manufacturing processes and materials ensure a long operational life and low maintenance requirements.
4. High Versatility: Multiple output methods (solid shaft, hollow shaft, with expansion disc, etc.) and flexible mounting orientations (horizontal, vertical) adapt to various application scenarios.
5. Smooth Operation & Low Noise: Precision gear machining ensures smooth transmission and low noise levels.
Series Models: ZD (Single-stage), ZDH (Two-stage), ZDSH (Three-stage)
Center Distance: Wide range, e.g., from a=100mm, 125mm, ... for ZD series to larger center distances for ZDSH series.
Transmission Ratio: Broad coverage.
ZD (Single-stage): Common range ~1.25 - 5.6
ZDH (Two-stage): Common range ~6.3 - 20
ZDSH (Three-stage): Common range ~22.4 - 100
Input Power: Ranges from a few kilowatts to several hundred kilowatts, depending on the center distance and model.
Output Torque: Ranges from hundreds of Newton-meters to tens of thousands of Newton-meters.
Lubrication Method: Typically splash lubrication (oil bath lubrication).
Note: Exact parameter values MUST be confirmed with the manufacturer's specific product catalogs and manuals, as they can vary.
The ZD/ZDH/ZDSH series reducers are general-purpose power transmission devices in heavy industries, widely used in:
Conveying Equipment: Belt conveyors, apron conveyors, bucket elevators.
Metallurgical Machinery: Steel rolling equipment, straightening machines, wire drawing machines.
Mining Machinery: Crushers, ball mills, scraper conveyors.
Chemical Machinery: Mixing equipment, extruders.
Lifting & Transportation: Overhead cranes, winches, port cranes.
General Industry: Drives on various production lines, such as paper machinery, rubber machinery, etc.
