Cycloidal pinwheel reducer introduction
All the transmissions of the planetary cycloidal reducer can be divided into three parts: the input part, the deceleration part and the output part. A double eccentric sleeve with a 180° misalignment is mounted on the input shaft, and two roller bearings called a jib are mounted on the eccentric sleeve. The central hole forming the H mechanism and the two cycloidal wheels is an eccentric sleeved slewing bearing. a raceway, and the cycloidal wheel and the needle gear are engaged with a set of annularly arranged pin teeth to form an internal meshing speed reduction mechanism with a tooth difference of one tooth (in order to reduce friction, in a reducer with a small speed ratio) , the needle teeth have a pin sleeve). When the input shaft rotates one year with the eccentric sleeve, the movement of the cycloidal wheel becomes a plane motion with both revolution and rotation due to the characteristics of the tooth profile curve on the cycloidal wheel and the restriction on the pin gear on the needle gear. When the input shaft rotates positively, the eccentric sleeve also rotates for one week, and the cycloidal wheel rotates one tooth in the opposite direction to obtain the deceleration, and then the W output mechanism is used to transmit the low speed rotation movement of the cycloidal wheel through the pin shaft to the output shaft. This results in a lower output speed.
Cycloidal pinwheel reducer features
High-speed ratio and high-efficiency single-stage transmission can achieve a reduction ratio of 1:87, and the efficiency is above 90%. If multi-stage transmission is adopted, the reduction ratio is larger.
Compact size and small size Due to the planetary transmission principle, the input shaft output shaft is on the same axis, making the model as small as possible.
Smooth running noise Low cycloidal pin teeth have a large number of teeth, a large overlap coefficient and a mechanism for balancing the components, so that vibration and hum are limited to a minimum.
Reliable use and long service life Because the main parts are made of high-carbon chrome steel, high strength is obtained by quenching treatment (HRC58~62), and some transmission contacts adopt rolling friction, so the durability is long.
The design is reasonable, the maintenance is convenient, the assembly is easy to disassemble, the minimum number of parts and the simple lubrication make the cycloidal pinwheel reducer deeply trusted by users.

Scope of the cycloid reducer
The cycloidal pinwheel reducer is a kind of machine that realizes deceleration according to the principle of less tooth difference planetary transmission and cycloidal pin gear meshing. The machine is divided into horizontal, vertical, double-axis and direct-coupled assembly methods, which are the first choice for metallurgy, mining, construction, chemical, textile, light industry and other industries.
Main features of cycloid reducer
1. The reduction ratio is large and the efficiency is high: the first-stage transmission reduction ratio is 9~87, the double-stage transmission reduction ratio is 121~5133, the multi-stage combination can reach tens of thousands, and the pin gear meshes the sleeve type rolling friction, the meshing surface is not Relative sliding, so the first-stage deceleration efficiency is 94%.
2. Smooth operation and low noise: There are many pairs of teeth in contact during operation, large coincidence degree, stable operation, strong overload capability, low vibration and noise, and low noise of various specifications.
3, reliable use, long life: because the main parts are made of high carbon alloy steel quenching treatment (HRC58-62), and then refined, and the cycloidal teeth and the pin gear sleeve mesh to the needle teeth to form rolling friction, friction The coefficient is small, so that the meshing zone has no relative sliding and the wear is extremely small, so it is durable.
4. Compact structure and small volume: Compared with other reducers of the same power, the weight is smaller than 1/3. Because it is a planetary transmission, the input shaft and the output shaft are on the same axis to obtain the smallest possible size.
