The transmission process of H-type mixer
A double eccentric sleeve with a misalignment of 180 ° is installed on the input shaft of the mixer, and two roller bearings are installed on the eccentric sleeve to form an H mechanism. The middle hole of the two cycloid wheels is the raceway of the rotating arm bearing on the eccentric sleeve. The electric mixer of the mixer blade is meshed with a set of circular arranged needle gears on the cycloid wheel and the needle gear to form a small tooth difference internal meshing reduction mechanism. (In order to reduce friction, in reducers with low speed ratioses, needle teeth are equipped with needle tooth sleeves).
When the input shaft of the mixer rotates one revolution with an eccentric sleeve, due to the characteristics of the tooth profile curve on the cycloid wheel and its restriction by the needle teeth on the needle gear, the motion of the cycloid wheel becomes a planar motion with both revolution and rotation. When the input shaft rotates one revolution in the forward direction, the eccentric sleeve also rotates one revolution, and the cycloid wheel rotates one tooth difference in the opposite direction to achieve deceleration. Then, with the help of the W output mechanism, the low-speed rotation motion of the cycloid wheel is transmitted to the output shaft through the pin shaft, thereby obtaining a lower output speed.
