     Analysis of parallel move gear transmission principle, put forward by the three eccentric

shafts for utility model translation generator gear mechanism within the translation of a

shunt-type gear, and derive the formula for calculating the transmission ratio. Analysis, to

balance the inertia force, using 2 (or 3) pieces of translation gear, the meshing point of the

design phase should take 180 ° (120 °); input gear teeth as a multiple of 3, the shunt gear

with interchangeability; with two translation gear and the internal and external gear tooth

number difference is even, Ping gear has interchange ability; with three flat gear and internal

gear teeth as a multiple of 3, the flat gear has interchangeability. Meshing parameters given

programming account Calculation method. The new drive has a carrying capacity, transmission

ratio (17-300), small size, light weight, input and output coaxial line, and simple

installation process is an energy-efficient mechanical transmission device, is also a new

generation product reducer . Have broad application prospects.

  Keywords: Internal translation gear transmission;differential gears with small teeth;
