The invention relates to a single-input coaxial double-output speed reducer which comprises an input gear shaft, an output shaft I, a hollow output shaft II, a planetary gear speed reducing mechanism and a bevel gear diversion reversing mechanism, wherein the power is input through a sun gear on the input gear shaft; the power is transmitted into the output shaft I from a planet carrier by the planetary gear speed reducing mechanism; part of the power is directly output by the output shaft I, and the other part of the power is transmitted into the output shaft II sheathed on the output shaft I in an idle way by the bevel gear diversion reversing mechanism; the output shaft II can output the power at the speed equal to that of the output shaft I along the direction opposite to that of the output shaft I. The single-input coaxial double-output speed reducer is simple in structure and reasonable in design, and can realize the transmission requirements of mixing equipment to a concentric double-shaft mixing system only by using a set of powder device, thus greatly saving the using space and lowering the production cost.

The invention provides a machining method of an injection molding face gear electrode and an injection molding face gear. A face gear transmission principle is used, a three-dimensional vector diagram of the face gear is generated in a generating method through computer-assisted software, then the injection molding face gear electrode is machined through a numerical control lathe, a mold cavity of the face gear is machined in an electric spark discharge technology, and accordingly the face gear is formed by infection molding. Due to the fact that transmission data of the face gear and a cylinder gear is simulated in a computer, the machined infection molding face gear completely meets face gear transmission requirements in practice, data is accurate, the face gear is fixed on a table face to be machined through the numerical control lathe, deformation cannot happen, and therefore the machined injection molding face gear electrode is high in accuracy and low in transmission noise. What is important is that technologies such as gear inserting or gear rolling or gear grinding are not used in machining of the injection molding face gear electrode, so that special knives are of no need, and cost is greatly lowered.
