Cycloidal pinwheel reducer is a common type of reducer, which is widely used in various mechanical transmission systems. It adopts the principle of cycloidal pinwheel transmission, which has the characteristics of high reduction ratio, large torque transmission, smooth operation and compact structure. This article will introduce the working principle of cycloidal pinwheel reducer in detail to help readers better understand how it works.
1. The composition of the cycloid reducer.
The cycloidal pinwheel reducer is mainly composed of input shaft, cycloidal wheel, pinwheel and output shaft. The input shaft is equipped with an active cycloidal wheel, and the output shaft is equipped with a driven cycloidal wheel and a pinwheel. The toothed parts of the needle wheel and the cycloidal wheel are generally made of hard tooth surfaces, which have high wear resistance and service life.
Second, the working principle of the cycloidal pin wheel reducer.
1.Transmission principle.
The transmission principle of the cycloidal pinwheel reducer is based on planetary gear transmission and less gear difference transmission. When the input shaft drives the active cycloidal wheel to rotate, through the toothing, the active cycloidal wheel drives the driven cycloidal wheel and the pinwheel to rotate, so as to achieve the purpose of deceleration. Due to the special curve design of the toothed part of the cycloidal wheel and the pinwheel, the cycloidal wheel can slide back and forth along the cogging direction of the pinwheel during rotation, so as to realize the continuous operation of the reducer.
2.Reduction ratio calculation.
The reduction ratio of the cycloidal reducer is one of its important technical parameters, which determines the deceleration capacity of the reducer. The formula for calculating the reduction ratio is: i = (z2 z1) *d2 d1) *n2 n1), where z1 and z2 are the number of teeth of the active and driven cycloidal wheels, d1 and d2 are the diameters of the active and driven cycloidal wheels, and n1 and n2 are the rotational speeds of the input and output shafts.
3.Running characteristics.
The running characteristics of the cycloidal reducer are one of its important performance indicators. In the process of reducer operation, due to the special toothing design of the cycloidal wheel and the pinwheel, the reducer has a large torque transmission capacity, and at the same time runs smoothly and has low noise. In addition, because the gearing part of the reducer adopts the rolling friction method, it has a high transmission efficiency, reducing power loss and temperature rise.
Third, the application of cycloidal pinwheel reducer.
Cycloidal pinwheel reducer is widely used in various mechanical transmission systems, such as textile machinery, printing machinery, packaging machinery, mining machinery, petrochemical machinery, etc. Its main function is to reduce the speed and increase the torque to meet the different needs of various mechanical equipment for power output. Compared with other types of reducers, cycloidal pinwheel reducers have higher bearing capacity and longer service life.
In short, this paper gives a detailed introduction to the working principle of cycloidal reducer, including its composition, transmission principle, reduction ratio calculation and operation characteristics. By understanding the working principle of the cycloidal pinwheel reducer, it is helpful to better understand its advantages and characteristics in practical applications, and to further promote and apply the cycloidal pinwheel reducer.
