This article is mainly from the following aspects to a cylindrical gear reducer design: First,reasonable gear design,understanding the mechanical transmission principle and parameter matching design levels,transmission parts and Assembly Sketches provide a basis. In Second, design and calculation of transmission parts, gear, shaft, bearing, coupling design choices and correction, to prepare for the design of the assembly drawing. Third, the design of gear reducer structure and its accessories in order to improve efficiency, reduce cost, make the maintenance easy. Fourth, the design of the reducer assembly drawing and parts working drawing for machine assembly, commissioning and maintenance. Keywords:?
