The sprocket is based on the imperial unit in our country.There are 3 points, 4 points, 5 points, 6 points, etc., as well as odd, double, triple, and quadruple rounds.The row spacing of two rows, three rows and four rows are all made according to the national standard.
其次还有以字母A、B为型号的链轮,A为片式链轮 B代表台式链轮,以B1-2-3中的1、2、3分别代表单排、双排、三排链轮,不同分数的链轮齿厚都不一样的。
The sprocket is driven by a chain, and the model unit is generally English.There are single row, double row and multiple rows.Suitable for low speed, heavy load and high temperature conditions.Compared with gears, it can be used where the cores of the two shafts are far away.Gears are driven by meshing with each other, and the model unit is mostly metric, expressed by modulus.The power and speed range of the transmission is relatively large.The compact structure can achieve a large transmission ratio, high efficiency and long service life.
