China Suppliers Factory - BW/XW Cycloidal Pinwheel Gearbox Speed Reducer for High Efficiency Power Transmission

,

The cycloidal reducer, also known as a planetary cycloidal reducer, is an advanced transmission device that operates on the principle of planetary transmission. It efficiently transmits power through the meshing of cycloidal needle teeth. This remarkable machine consists of three main parts: the input section, the deceleration section, and the output section. The input shaft drives the cycloidal gear through a double eccentric sleeve, facilitating a unique combination of revolution and rotation.
Our cycloidal reducers boast a single-stage transmission reduction ratio of up to 1:87 and an impressive transmission efficiency exceeding 90%. When using multiple stages, the reduction ratio can reach remarkable levels in the tens of thousands. Featuring a coaxial design for both the input and output shafts, this reducer is characterized by a compact structure that provides exceptional load-bearing capacity. Key components are manufactured from high carbon chromium steel and utilize a rolling friction structure that significantly extends operational lifespan. To maintain optimal performance, it's essential to regularly replace the mechanical oil or extreme pressure gear oil within the lubrication system. This ensures reliable operation for both forward and reverse motions. Additionally, it’s crucial that the output shaft is not subjected to excessive axial or radial forces.
As a leading factory and supplier in China, we are committed to delivering high-quality cycloidal reducers that meet the diverse needs of our clients worldwide.

    Product Features
    • 1
      High Speed Ratio & High Efficiency Single-stage transmission can achieve a reduction ratio of 1:87, with an efficiency of over 90%. If multi-stage transmission is used, the reduction ratio is even greater.
    • 2
      Compact Structure & Small Volume Due to the use of planetary transmission principle, the input and output shafts are on the same axis, making the model achieve the smallest possible size.
    • 3
      Smooth Operation with Low Noise The cycloid needle teeth have a large number of meshing teeth, a high overlap coefficient, and a mechanism of mechanical balance, which minimizes vibration and noise.
    • 4
      Reliable Use & Long Service Life The main components are made of high carbon chromium steel material, quenched (HRC58–62) to obtain high strength. Transmission contacts use rolling friction, ensuring durability and long service life.
    Conditions of Use
    1
    The cycloidal pinwheel reducer is allowed to be used in continuous working conditions and can operate in both forward and reverse directions.
    2
    The rated speed of the input shaft is 1500 RPM. A 6-pole motor with a speed of 960 RPM is recommended when the input power exceeds 18.5 kW.
    3
    The working position of the horizontally installed reducer is always horizontal. Maximum horizontal tilt during installation is generally less than 15°. When exceeded, additional measures should ensure sufficient lubrication and prevent oil leakage.
    4
    The output shaft cannot withstand large axial and radial forces. Other measures must be taken when significant axial and radial forces are present.

    Frequently Asked Questions
    Q What is the maximum reduction ratio achievable with a cycloidal pinwheel reducer?
    A single-stage cycloidal pinwheel reducer can achieve a reduction ratio of up to 1:87 with an efficiency of over 90%. When multi-stage transmission is used, the reduction ratio can be even greater, making it suitable for applications requiring very low output speeds.
    Q Can the cycloidal pinwheel reducer operate in both forward and reverse directions?
    Yes. The cycloidal pinwheel reducer is designed for continuous working conditions and fully supports both forward and reverse operation, providing flexible integration into various industrial drive systems.
    Q What is the rated input shaft speed for this reducer?
    The rated speed of the input shaft is 1500 revolutions per minute. For applications where the input power exceeds 18.5 kW, it is recommended to use a 6-pole motor operating at 960 RPM to ensure optimal performance and longevity.
    Q What materials are used in the construction of the cycloidal pinwheel reducer?
    The main components are manufactured from high carbon chromium steel, which undergoes quenching treatment to achieve a hardness of HRC58–62. This ensures exceptional strength and wear resistance. Rolling friction is used at key transmission contact points to further extend service life.
    Q Is there a maximum tilt angle for horizontal installation?
    Yes. For horizontally installed cycloidal pinwheel reducers, the maximum allowable tilt angle during installation is generally less than 15°. If the tilt angle exceeds this limit, additional measures must be implemented to ensure adequate lubrication and to prevent oil leakage during operation.
    Q Can the output shaft handle large axial and radial forces?
    No. The output shaft of the cycloidal pinwheel reducer is not designed to withstand large axial or radial forces. If your application involves significant axial or radial loading, additional mechanical measures — such as external support bearings or flexible couplings — must be incorporated into the system design.
