The principle, characteristics and application scope of cycloidal pinwheel reducer

The cycloidal pinwheel reducer, as an important mechanical transmission device, has a unique structure and excellent performance.

 

First of all, let’s understand its principle. The entire transmission device of the planetary cycloidal pinwheel reducer is divided into three parts: input, reduction and output. The input shaft is equipped with a double eccentric sleeve with a dislocation of 180°, and the rocker arm bearings on the eccentric sleeve form an H mechanism. The center hole of the cycloidal gear serves as the raceway of the rocker arm bearing and meshes with the pin teeth on the pin gear to form an internal meshing reduction mechanism with a tooth difference of one tooth. When the input shaft rotates with the eccentric sleeve for one week, due to the characteristics of the tooth profile curve and the restriction of the pin teeth, the cycloidal gear undergoes a planar motion that has both revolution and rotation, thereby achieving deceleration. Then, the low-speed rotation is transmitted to the output shaft through the output mechanism to obtain a lower rotational speed.

 

 

Then let’s look at its characteristics. The cycloidal reducer has a high speed ratio and high efficiency. A single-stage transmission can achieve a reduction ratio of 1:87, with an efficiency of over 90%. The reduction ratio of multi-stage transmission is even greater. The structure is compact and the volume is small. Based on the principle of planetary transmission, the input shaft and the output shaft are on the same axis. It operates smoothly with low noise due to the large number of meshing teeth of the cycloidal pin teeth, the large overlap coefficient and the balance mechanism of the machinery. It is reliable in use and has a long service life. The main parts are made of high-carbon chromium steel materials and quenched. Some transmission contacts are rolling friction. The design is reasonable, maintenance is convenient, there are few parts and lubrication is simple, which is deeply trusted by users.

 

 

Its models are diverse, including the B series and the X series. Each series has different installation methods and motor connection forms to meet various application requirements.

 

 

In terms of the scope of use, the cycloidal pinwheel reducer operates in accordance with the principle of planetary transmission with few tooth differences and is suitable for many industries such as metallurgy, mining, construction, chemical engineering, textile, and light industry. It is the preferred equipment in these fields.

 

 

The main characteristics include a large reduction ratio and high efficiency. The reduction ratio of single-stage transmission can reach 9 – 87, and the reduction ratio of double-stage transmission is even higher. The efficiency of single-stage reduction reaches 94%. It operates smoothly with low noise. At the same time, there are many pairs of contact teeth, a large degree of coincidence, and strong overload capacity. It is reliable in use and has a long service life. The main parts are quenched and ground precisely with high-carbon alloy steel. The cycloidal teeth and the pin tooth sleeves form rolling friction with minimal wear. The structure is compact and the volume is small. Planetary transmission enables the input shaft and the output shaft to be on the same axis, with obvious size advantages.
