Study on the Design Program for Non-standard Plastic Gear

Abstract

Key Words：Gear(기어), Non-Standard(비표준), Plastic(플라스틱), Design Program(설계 프로그램)Abstract：Currently, plastic gear is widely used as parts of office equipment and industrial machines, because plastic substance has an advantage of light weight and possible to operate in oil-fewer conditions. However, under cyclic loadings, their occurred repetitive deformation due to weak tensile strength and bending stress rather than metal gear. Furthermore, they have a problem of attrition and breakage owing to frictional heat. For solving these problems, when plastic gear's opponents are metal gear, we should design that plastic gear's tooth be thick and metal gear's tooth be thin. In this research, we developed the program which developing tooth profile of non-standard gears automatically and calculating over-pin diameter for inspection after making gear. 허문범(교신저자) : 중앙대학교 기계공학부
