introduction： Different applications，Lead to a difference in the choice of products，The choice of brand and product is mainly based on the practical application。 There are two main types of precision planetary reducer according to the output direction：Straight and right Angle； There are generally three kinds of precision planetary reducer according to the series：First stage reduction（Generally less than10：1）、Secondary reduction（Generally greater than10：1Less than or equal to200：1）、Three-stage reduction（Some brands dont have a third level，Maximum deceleration ratio achieved100：1，The general division principle is greater than100：1），But the miniature planetary reducer can do five stages，The deceleration ratio is maximum achieved4
