China Cycloidal Pinwheel Gearbox Speed Reducer - Factory Suppliers for High Efficiency Transmission Solutions
Product Features
-
1High Speed Ratio & High Efficiency: Single-stage transmission achieves a reduction ratio of 1:87 with over 90% efficiency. Multi-stage transmission enables an even greater reduction ratio.
-
2Compact Structure & Small Volume: Utilizing planetary transmission principles, the input and output shafts share the same axis, resulting in the smallest possible overall size.
-
3Smooth Operation & Low Noise: Cycloid needle teeth feature a large number of meshing teeth, a high overlap coefficient, and a mechanically balanced design — minimizing vibration and noise.
-
4Reliable & Long Service Life: Main components are crafted from high carbon chromium steel, quenched to HRC58–62 for superior strength. Rolling friction at transmission contacts ensures outstanding durability.
Conditions of Use
-
⚙️The cycloidal pinwheel reducer is designed for continuous working conditions and supports both forward and reverse operation.
-
⚡The rated input shaft speed is 1,500 RPM. For input power exceeding 18.5 kW, a 6-pole motor running at 960 RPM is recommended.
-
📐For horizontal installation, the unit must remain level during operation. The maximum tilt angle during installation is generally less than 15°. If the angle exceeds 15°, additional measures must be taken to ensure proper lubrication and prevent oil leakage.
-
🔩The output shaft cannot withstand large axial or radial forces. When significant axial or radial loads are present, additional support measures must be implemented.

Frequently Asked Questions
Q
What is the maximum reduction ratio achievable with the cycloidal pinwheel reducer?
In a single-stage configuration, the reducer achieves a reduction ratio of up to 1:87. When multi-stage transmission is applied, the overall reduction ratio can be significantly greater, making it suitable for applications requiring very low output speeds.
Q
What is the transmission efficiency of this reducer?
The cycloidal pinwheel reducer delivers a transmission efficiency of over 90% in single-stage operation. This high efficiency is achieved through the planetary transmission design and the use of rolling friction at key transmission contact points.
Q
Can the reducer operate in both forward and reverse directions?
Yes. The cycloidal pinwheel reducer is fully capable of operating in both forward and reverse directions under continuous working conditions, offering great flexibility for various industrial applications.
Q
What motor speed is recommended for input power greater than 18.5 kW?
For input power exceeding 18.5 kW, it is recommended to use a 6-pole motor operating at 960 revolutions per minute. The standard rated input shaft speed for the reducer is 1,500 RPM.
Q
What material is used for the main components, and how durable is it?
The main components are manufactured from high carbon chromium steel, which undergoes a quenching process to achieve a hardness of HRC58–62. This, combined with rolling friction at transmission contacts, ensures exceptional strength, wear resistance, and a long service life.
Q
Are there any limitations on axial and radial forces on the output shaft?
Yes. The output shaft of the cycloidal pinwheel reducer is not designed to withstand large axial or radial forces. If the application involves significant axial or radial loads, additional mechanical support measures — such as external bearings or couplings — must be implemented to protect the unit.
