Planetary Speed Reducer

Planetary speed reducer consists of sun wheel, planetary wheel, internal gear ring and planetary carrier, the transmission efficiency is as high as 97%, and the output torque is large, the structure is compact, the operation is smooth, and the service life is long. Widely used in industrial automation, robotics and other fields. The advantages of our products are as follows:

1. Hansheng high speed planetary gearbox's excellent transmission precision, accuracy ≤ 1 arc minute. High-precision gear assembly with multiple planetary gears meshing reduces gear meshing backlash and improves transmission precision.

2. Many planetary gears mesh with the center gear to increase torque generating. It is suitable for machines when space is limited and high torque output is required as the torque output may be several hundred Nm.

3. Low friction material with high precision gear design, transmission efficiency can reach more than 95%. Multi-stage deceleration system maximizes power transmission.

4. The compact construction of the planetary speed reducer enables high ratios and torque outputs in applications where space is limited.

5. Highly strong alloy steel makes up the gear material. It is heat-treated and toughened. Additionally carefully machined and designed to provide good wear resistance for high-frequency, high-intensity industrial uses are bearing and gear components.

6. There are several speed ratios to suit a range of industrial requirements. Users may choose the suitable reduction ratio depending on speed and torque output needs and applications from ratios ranging from 3-100 ratios. Quite flexible in robotics, packaging, automation tools, and other sectors.

7. The planetary reducer gears are designed with great care and the gears bite with particular precision, so the sound when working is very small, generally not more than 65 dB, which is fully in line with the low noise standard. Moreover, its planetary gears are arranged symmetrically, which not only transmits power more stably, but also reduces vibration and makes the machine run especially smoothly.

8. Compact construction facilitates small, high ratios and high torque outputs in space-constrained applications. It also provides greater flexibility

Gear manipulation

Precision CNC machines and high-strength alloy steel materials enable gear processing. Advanced hobbing or grinding tools finish the tooth profile of gears thereby guaranteeing great precision and smoothness of their tooth surfaces. Usually carburizing and quenching treatment helps gears to improve their hardness and wear resistance; the surface hardness can reach HRC58-62. Gears still need to be ground after quench to further lower tooth surface roughness and guarantee low friction and noise free operation.

Shell processing

Usually, cast iron or aluminium alloy forms the casing. Using CNC tools for precise drilling and cutting, the shell processing guarantees the dimensional accuracy of the internal cavity and external mounting surface. Sandblasting or anodizing the shell's surface will help to improve its wear and corrosion resistance. To guarantee great accuracy during component assembly, machining tolerances of all shells are tightly regulated at the micrometer level during the machining process.

Shore machining and bearings

High-precision turning and honing of the bearings and planetary gear shafts guarantees their dimensional tolerances and concentricity. By means of heat treatment, these bearings and shafts will improve their hardness and strength, thereby raising their load-bearing capability. Dynamic balancing testing is another necessary technique for the treated shaft components to guarantee the gearbox stays vibration free and stable during high-speed running.

Assembly procedure

In the production process, assembly is an absolutely vital stage. To guarantee high-precision assembly in a hygienic surroundings, all elements are assembled in a dust-free workplace. Every gear component must be rigorously dimensional inspected and tested for backlash during the assembly process to guarantee gear meshing's precision and stability. To guarantee the decelerator's long-term stable performance, lubricating grease fills it lastly and it is sealed.
