Abstract

This paper describes two helical gear reducer design and design process, the further transformation of the machine tool. Gear reducer drive system is the most important part, especially the box, very high accuracy requirements, need to consider the impact of other aspects of the drive shaft. In the analysis of the structure and performance characteristics of various reducer, based on and use a variety of relevant information and practical experience, comprehensive consideration a variety of performance, precision, stability, economic design, practicality relatively strong, to design a 2 stage helical gear reducer drive system. Through the experience of the estimates to the checking does not conform to certain components on the right improvements, repeatedly modified until the meet the requirements, and through two-dimensional mapping software, AutoCAD drawings, modify the structure of irrational place. In this paper, the design options of the program analysis and comparison, the choice of parts checked and analysis, the two helical gear reducer design steps made an introductory, and some design steps has been simplified.

Key words: Two helical gear reducer ；Strength Calculation；Assembly
