Cycloidal reducer features, working principle, advantages and uses

The cycloidal pinwheel reducer is designed based on the KHV small tooth difference planetary transmission principle. The planet wheel (cycloid wheel) teeth are cycloid teeth, and the sun mechanism cycloid wheel (needle wheel) is pin teeth. They are composed of both The cycloidal pinwheel pair is obtained, and the difference between the number of pinwheel teeth Zp and the number of cycloidal wheel teeth Zc is 1.During the transmission process, the rotating arm arm transmits the input motion to the cycloidal wheel.Due to the function of the fixed pinwheel, the cycloid wheel produces a low-speed rotation motion opposite to the input motion, and then outputs it through the W mechanism.

The rotating arm is composed of an input shaft and an eccentric sleeve. The two eccentrics on the eccentric sleeve are 180° to each other.In order to reduce friction loss, two roller bearings are installed between the eccentric sleeve and the cycloidal wheel.

The tooth shape of the cycloidal wheel is a short epicycloid equidistant curve.Originally, only one cycloid wheel can be used to transmit motion according to the motion requirements. In order to achieve static balance of the input shaft and improve the shaft load capacity of the motion, two identical odd-numbered cycloid wheels are used, respectively installed on the eccentric sleeve. .The positions of the two cycloidal wheels differ by 180 degrees.

The pinwheel is composed of a pinwheel shell and an even number of pins installed in the pin holes of the pinwheel shell.A pin tooth sleeve can be installed on the pin tooth pin to reduce the joint friction loss. The mechanism composed of the output shaft, pin shaft and cycloidal wheel is usually called a W mechanism.The connection between the cycloidal wheel and the output shaft is achieved by a pin.

One end of the pin is fixed on the flange of the output shaft, and the other end is inserted into the equal distribution holes of the two cycloid wheels.In order to reduce friction loss, a pin sleeve is installed on the cantilever of the pin shaft.

Advantages and features of XB cycloidal reducer

The transmission ratio is large: the transmission ratio for one-stage deceleration is 1/9~1/87; the transmission ratio for two-stage deceleration is 1/99~1/7569; more stage combinations can be used as needed.

High transmission efficiency: Since the meshing part of the machine adopts rolling meshing, the average efficiency can reach more than 90%. Small size and light weight: Since the planetary transmission principle is not used, the input shaft and output shaft are on the same axis, and there is a connection with the motor. Due to the unique direct-coupled structure, this machine has the characteristics of compact structure, small size and light weight.

Fewer faults and long life: The main transmission meshing parts of this machine are made of bearing steel, so it has good mechanical performance and good wear resistance. In addition, it uses rolling friction, so it has fewer faults and long life.

Reliable and stable operation: This machine uses multi-tooth meshing during transmission, so it operates stably and reliably with low noise.

Easy to disassemble and assemble, easy to maintain: Due to the reasonable structural design, it is easy to disassemble and assemble for easy maintenance.

XB cycloidal reducer uses:

Sewage treatment mixing, chemical plant reactors, steel plants, copper industry, food, rubber, chemical industry, electric power, energy, environmental protection, metallurgy, port metallurgical mining, petrochemical industry, construction, lifting and transportation, textile printing and dyeing, engineering machinery, food Industry and other industries.

This machine also has the characteristics of strong overload capacity, impact resistance, and small inertia moment, which is suitable for frequent starting and forward and reverse rotation.
