Cycloidal pin gear reducer is a novel transmission device that applies the principle of planetary transmission and adopts cycloid pin-tooth meshing.The entire transmission device of the cycloid reducer can be divided into three parts: input part, deceleration part and output part.A double eccentric sleeve with misalignment degree is installed on the input shaft, and two roller bearings called rotating arms are installed on the eccentric sleeve to form an H mechanism. The raceway, and the cycloid wheel meshes with a set of circularly arranged pin teeth on the pin gear to form an internal meshing reduction mechanism with a tooth difference. (In order to reduce friction, in a reducer with a small speed ratio, pins with pin sleeves on the pins).
When the input shaft rotates a circle with the eccentric sleeve, due to the characteristics of the tooth profile curve on the cycloid wheel and the limitation of the needle teeth on the pin gear, the movement of the cycloid wheel becomes a plane motion with both revolution and rotation. When the input shaft rotates one revolution forward, the eccentric sleeve also rotates one revolution, and the cycloid wheel rotates one tooth in the opposite direction to obtain deceleration, and then with the help of the W output mechanism, the low-speed self-rotation motion of the cycloid wheel is transmitted to the output shaft through the pin shaft, This results in a lower output speed.
How to distinguish between planetary reducer and cycloid reducer
How to differentiate?The specific difference lies in the type of internal gears. The interior of the planetary reducer is a planetary gear, and the cycloid is a pin wheel (there are also planetary cycloids, multi-stage reducers). From the outside, the planetary reducer is mostly directly connected to the motor, and the cycloid can be rotated. It can be directly connected to the motor.
Calculation method of speed ratio of cycloidal pinwheel reducer.
Single-stage transmission ratio: 9, 11, 17, 23, 29, 35, (39), 43, (47), 59, 71, 87
Two-stage transmission ratio: (11*11), (17*11), (17*17), (29*17)
The two-stage transmission ratio is the product of two single-stage transmission ratios, and the above is commonly used.
