introduction：1.In a pair of gears，Gears with fewer teeth are called pinion gears，A gear with many teeth cogwheel，When the number of teeth is equal，The driving gear is called a pinion，The driven gear is called the big gear； 2.In an external gear，It works backwards for you，Turn the pinion to the right，The big gear turns to the left； 3.In an inner gear，Both gears run in the same direction； 4.In a pair of gears，Run number、The number of teeth is inversely proportional，A small gear has more revolutions than a big one，Its tooth ratio，Gear ratio of reducer is as follows： Gear ratioⅰ＝ Number of big gear teeth/pinion
