The principle of cycloidal reducer
Its principle is like two silver coins, one is stationary and the other is rotating against its edge. When the rotating coin returns from one point to the original point, it has already turned two times instead of one.
It is composed of gears inside, and the combination of dynamic and stationary gears is not externally engaged like a silver coin. Instead, one outer edge and another inner edge are engaged to form a group, which saves space and can be stacked in a cylinder even if multiple groups are combined. The input and output shafts of the cylinder are on the same circle center, but the internal gears are not concentric. The driving wheel is smaller than the driven wheel and swings along the shaft while rolling along the side. Drive the driven wheel to roll; the driven wheel drives the next driving wheel to swing along the shaft...and so on until the output shaft. The number of teeth and gear sets in each set determines the gear ratio.
Just make sure the oil is normal every day. However, when the oil leakage of the sealing ring occurs, remember to replace the sealing ring. When replacing, just remove the motor screws, do not remove the reducer screws. After dismantling, remove the motor fan cover. Pull out the motor while turning the fan blade. When replacing the rear motor, also turn the fan blades. There are also problems with the oil pump. Transparent oil pipes are prone to oil leakage. When disassembling the reducer, be sure to remember the orientation markings of each gear for easy replacement.
Principle of cycloidal reducer/structure principle of cycloid reducer
The entire transmission device 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 dislocated by 180° is installed on the input shaft, and two roller bearings are installed on the eccentric sleeve to form an H mechanism. The center hole of the two cycloidal wheels is the raceway of the arm bearing on the eccentric sleeve, and The cycloidal gear is meshed with a group of annularly arranged needle gears on the needle gear to form a small tooth difference internal meshing deceleration mechanism, (in order to reduce friction, in the reducer with a small speed ratio, the needle teeth are provided with needle gear sleeves. )
When the input shaft rotates with the eccentric sleeve for one week, due to the characteristics of the tooth gallery curve on the cycloid wheel and the limitation of the needle teeth on the needle gear, the movement of the cycloid wheel becomes a plane movement with both revolution and rotation. When the input shaft rotates for one round, the eccentric sleeve also rotates one round, and the cycloid wheel rotates in the opposite direction through a tooth difference to obtain deceleration. Then, with the help of the W output mechanism, the low-speed autorotation motion of the cycloid wheel is transmitted to the output through the pin shaft. shaft to obtain a lower output speed.
Planetary cycloidal reducer/cycloid reducer is a relatively new type of transmission mechanism, its unique stable structure can replace ordinary cylindrical gear reducer and worm gear reducer in many cases.
Cycloidal pinwheel reducers are widely used in various industries and fields
Cycloidal pinwheel reducer is a novel reduction device that adopts the principle of planetary transmission with less tooth difference, which can be widely used in petroleum, environmental protection, chemical industry, cement , transportation, textile, pharmaceutical, food, printing, lifting, mining, metallurgy, construction , power generation and other industries, as a driving or deceleration device, the applicable working temperature is plus or minus 40 degrees. Therefore, the cycloid reducer is widely welcomed by users and is widely used in various industries and fields.
