Planetary reducer, as a precision industrial transmission equipment, has a unique design and powerful functions. Planetary reducer has a high degree of flexibility and customizability through modular design, and can quickly adapt to different working scenarios and transmission requirements. The working principle of the planetary reducer is that an inner gear ring is tightly combined with the gearbox housing, and the center of the ring gear has a sun gear driven by an external power. In between there is a planetary gear set consisting of three gears equally divided and assembled on the tray. When the input power drives the sun gear, it can drive the planetary gears to rotate and revolve along the center following the trajectory of the inner gear ring, and then output power through the output shaft connected to the tray. This planetary reducer is designed to increase the contact area of the output end. We have specially optimized the structure of the output end. By increasing the size of the contact surface and using high-strength materials, the output end's ability to withstand loads has been significantly improved. This design enables the planetary reducer to operate more stably and reliably when facing high-load conditions, effectively extending the service life of the equipment and improving overall work efficiency.
Product Introduction
The Output Variable High Precision Torque Planetary Reducer ALR Series utilizes helical gears to achieve smooth and quiet operation. The high-precision design maintains backlash below 6 arcminutes, providing precise positioning for motion control applications. Integral roller bearings enhance rigidity and torque capacity, supporting high-load operating conditions. A universal flange connection system allows installation on motors from global manufacturers. The cross-roller bearing output design reduces structural height while maintaining torque transmission capability. The lubrication system requires no oil changes over the product's operational life, with low internal wear contributing to extended service duration.

Common Questions and Solutions
How to select the correct ALR series model for my motor?
Match the motor shaft diameter, pilot diameter, and bolt circle dimensions against the ALR series flange specification table. The product data sheet provides compatibility information for major servo motor brands.
What reduction ratios are available in the ALR series?
Single-stage and multi-stage configurations are available. Typical ratios include 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 50, 60, 70, 80, 90, and 100. Consult the product catalog for ratio-specific specifications.
How does the cross-roller bearing output benefit my application?
Cross-roller bearings provide high moment load capacity and rotational accuracy while reducing the axial height of the output section. This design enables more compact machine layouts.
Is the lubrication truly maintenance-free?
Yes. The ALR series uses a sealed lubrication system that requires no oil changes over the product's operational life under rated operating conditions.
What torque ratings does the ALR series provide?
Torque ratings vary by frame size and reduction ratio. Refer to the technical datasheet for rated torque, peak torque, and emergency stop torque specifications for each model.
What is the expected service life under rated load?
The ALR series provides 20,000 hours of service life under rated operating conditions. Actual life depends on load profile, duty cycle, ambient temperature, and installation alignment.
Installation Considerations
Align motor shaft and reducer input bore within specified concentricity tolerances to prevent bearing stress and premature wear.
Apply torque values specified in the installation manual to mounting bolts. Overtightening may distort housing or damage threads.
Do not disassemble the reducer housing. The internal lubrication system is factory-sealed and does not require user access.
Operating temperature range: -10°C to +90°C. Extended operation outside this range may affect lubricant properties and seal performance.
For applications requiring frequent start-stop cycles or reverse rotation, consult the factory for thermal load assessment.
When mounting the reducer, ensure the output flange is properly supported to prevent cantilever loading beyond specified limits.
