X/B cycloid reducer is a kind of machinery that achieves deceleration by cycloid needle tooth meshing according to the principle of planetary transmission with less gear difference. The machine is divided into horizontal, vertical, double shaft type and direct connection type assembly, is the first choice of equipment for metallurgy, mining, construction, chemical industry, textile, light industry and other industries.

High power reducer structure and principle.

       Cycloid pinwheel reducer is a novel transmission device that applies the principle of planetary transmission and uses cycloid pintooth meshing. The whole transmission device of cycloid reducer can be divided into three parts: input part, reduction part and output part. The input shaft is equipped with a double eccentric sleeve misaligned 180°, and the eccentric sleeve is equipped with two roller bearings called swivel arms to form the H mechanism, the center hole of the two cycloid wheels is the raceway of the swivel arm bearings on the eccentric sleeve, and the cycloid wheels are meshed with a set of circularly arranged needle teeth on the needle gear to form the internal meshing reducer with a tooth difference, (in order to reduce friction, in the reducer with small speed ratio, the needle teeth are (In order to reduce the friction, in the speed reducer with small ratio, the needle teeth are equipped with a needle tooth sleeve).

       When the input shaft rotates with the eccentric sleeve for one week, the motion of the cycloid becomes a plane motion with both revolution and rotation because of the characteristics of the tooth profile on the cycloid and the restriction of the pin teeth on the pin gear, and when the input shaft is rotating for one week, the eccentric sleeve also rotates for one week, and the cycloid turns through one tooth in the opposite direction to get the deceleration, and then the low-speed rotation motion of the cycloid is transmitted to the output shaft through the pin with the help of the W output mechanism, so as to get a lower speed. Then, with the help of the W output mechanism, the low-speed rotation motion of the cycloid is transmitted to the output shaft through the pin, thus obtaining a lower output speed.

Performance characteristics.

1, the cycloid reducer reducer ratio is large, high efficiency: a drive reduction ratio of 9 ~ 87, two-stage drive reduction ratio of 121 ~ 5133, multi-stage combination can reach tens of thousands, and the needle tooth meshing system set of rolling friction, the meshing surface without relative sliding, so the first deceleration efficiency of 94%.

2, needle gear reducer running smoothly, low noise: the number of pairs of teeth in contact at the same time in operation, the degree of overlap, smooth operation, overload capacity, low vibration and noise, various specifications of the model noise is small.

3, reliable use, long life: because the main parts are made of high-carbon alloy steel quenching treatment (HRC58-62), and then finely ground, and the cycloid teeth and the needle tooth sleeve meshing transfer to the needle teeth to form a rolling friction payment, the friction coefficient is small, so that the meshing area without relative sliding, wear is very small, so durable. 

4, compact structure, small size: compared with other reducers of the same power, the weight volume is smaller than 1/3, because of the planetary transmission, the input shaft and output shaft in the same axis, to obtain the smallest possible size.
