The NLR series planetary reducer adopts a spiral bevel gear design, which allows high-speed input of the servo motor and obtains the torque output. The meshing spiral line has been optimized through motion error analysis, with high efficiency, long life, and maintenance-free. The output end screw hole design allows the screw to pass through the equipment end to fix the reducer to the customer's equipment.
Product Introduction
The NLR Series Spiral Bevel Gear Planetary Reducer is designed for crane applications driven by servo motors or stepping motors. The spiral bevel gear configuration enables high-speed input from the motor while delivering torque output suitable for hoisting and positioning operations. The meshing spiral line is optimized through motion error analysis to ensure transmission accuracy. The reducer operates with high efficiency and extended service life, requiring no maintenance over its operational duration. The output end incorporates screw holes that allow fasteners to pass through the equipment end, securing the reducer to customer equipment. This design supports the radial and axial load conditions typical in crane and material handling applications.

Common Questions and Solutions
How does the spiral bevel gear design benefit crane applications?
The spiral bevel gear configuration enables high-speed input from servo or stepping motors while efficiently converting to torque output suitable for hoisting and traversing. This design is particularly effective for crane drives requiring both speed range and torque capacity.
What reduction ratios are available in the NLR series for crane applications?
Single-stage and multi-stage configurations are available with reduction ratios suitable for crane hoisting and traversing speed requirements. Consult the product catalog for ratio-specific torque and speed ratings for servo and stepping motor compatibility.
How is the meshing spiral line optimized through motion error analysis?
Motion error analysis is applied during the design and manufacturing process to optimize gear tooth geometry. This ensures consistent transmission accuracy, reduces vibration, and maintains positioning precision in crane hoisting and traversing operations.
Is the NLR series suitable for both servo motor and stepping motor drives?
Yes. The NLR series is compatible with both servo motor and stepping motor drive systems. The spiral bevel gear design handles the input characteristics of both motor types while delivering the required torque output for crane applications.
What does maintenance-free operation mean for crane applications?
The NLR series is factory-sealed with lubricant that lasts the product's operational life. No scheduled grease replacement, oil changes, or internal component maintenance is required. Regular external inspection of seals and mounting bolts is still recommended.
How does the output end screw hole design secure the reducer to crane equipment?
The output end features precision screw holes that allow fasteners to pass through the customer's equipment mounting flange directly into the reducer housing. This provides secure fixation suitable for the vibration and load conditions in crane operations.
Installation Considerations
Align motor shaft and reducer input bore within specified concentricity tolerances to prevent bearing stress and maintain transmission accuracy.
Apply torque values specified in the installation manual to mounting bolts. Crane applications require periodic bolt torque verification due to vibration conditions.
Do not disassemble the reducer housing. The unit is factory-sealed and maintenance-free with no user-serviceable internal components.
When using output end screw holes for equipment fixation, select fastener length appropriate for the mounting flange thickness to ensure proper clamping without bottoming out.
Operating temperature range: -10°C to +90°C. For crane applications in extreme environments, consult the factory for temperature-specific lubricant recommendations.
Consider shock load conditions typical in crane starting and stopping. Select model frame size with appropriate peak torque margin for the specific crane duty cycle.
