Cycloidal pin wheel reducer

Cycloidal pin wheel reducer

Cycloid pinwheel reducer is a novel transmission device that applies the principle of planetary transmission and adopts cycloidal pinwheel meshing. Due to long-term high torque mechanical motion, the meshing clearance of the gearbox increases, causing significant noise and equipment vibration in the gearbox, bearing box, thread seal, mechanical seal and other parts of the cycloidal pinwheel reducer. In addition, the sealing part has been operating at high speed and high temperature for a long time, and oil leakage from the sealing part often occurs. Due to severe oil leakage during equipment operation, it brings numerous drawbacks to safety production. Traditional methods require long-term shutdown, disassembly, replacement of sealing gaskets, and treatment of joint surfaces. In order to achieve effective treatment during equipment operation, traditional methods cannot be used.

main features 
It can achieve a high reduction ratio of 1:87 and a high-efficiency single-stage transmission of over 90%. If multi-stage transmission is used, the reduction ratio will be even larger. The first stage transmission has a reduction ratio of 9~87, and the two-stage transmission has a reduction ratio of 121~5133. The multi-stage combination can reach tens of thousands, and the needle tooth meshing system has sleeve type rolling friction, with no relative sliding on the meshing surface. Therefore, the first stage reduction efficiency reaches 94%.

Due to the use of planetary transmission principle, the input and output shafts are on the same axis, resulting in a compact structure and small volume, making the model achieve the smallest possible size.

Smooth and low-noise operation with a large number of meshing teeth, high overlap coefficient, and mechanism of mechanical balance, which limits vibration and noise to a small extent.

During operation, there are multiple pairs of teeth that come into contact simultaneously, resulting in a high degree of overlap, smooth operation, strong overload capacity, low vibration and noise, and low noise levels for various specifications of models.

Reliable and long-lasting due to the use of bearing steel materials as the main components, which have undergone quenching treatment (HRC58-62) to obtain high strength. Additionally, some transmission contacts use rolling friction, resulting in long durability and longevity.

Due to the fact that the main components are made of bearing steel quenched (HRC58-62) and then finely ground, and the cycloidal teeth mesh with the needle gear sleeve to form a rolling friction pair, the friction coefficient is small, resulting in no relative sliding in the meshing area and minimal wear, making it durable.

Reasonable design, easy maintenance, easy disassembly and installation, fewer parts, and simple lubrication make the cycloidal pinwheel reducer highly trusted by users.

Compared with other reducers of the same power, the weight and volume are more than one-third smaller. Due to the planetary transmission, the input shaft and output shaft are on the same axis to achieve the smallest possible size.
