Abstract锛毬燗s to the automatic tightening mechanism of front end wheel for high power diesel engine锛?the function in the system锛?the design indicators and the test requirements is analyzed锛?and in this way the design of the key component of the vortex spring of automatic tensioning mechanism is carried out. Through the finite element analysis calculation锛?the reliabi聽-lity test of the platform and the actual installation reliability test锛?the various indices of the automatic tensioning mechanism are met and the design goals are achieved. By the time of this study锛?the design and experimental method used in this paper provide the basis for similar product development in the later stage.Keywords锛?High power diesel engine; Automatic tightening mechanism; The finite element analysis; The reliability testCLC NO.锛毬燯461.1 聽document Code锛?A 聽Article ID锛?1671-7988锛?020锛?1-90-04
