One of the main\r\nfailures in combines is breaking shaft which repairmen refer it.\r\nStructural resistance of canal against torque is very important in the\r\nbeginning of the movement. For analyzing stress, a typical sample\r\nfrom a type of combine was selected, called JD955 combine. Long\r\nshaft in this combine was analyzed with finite element method by\r\nAnsys13 generic package under static load. Conducted analysis\r\nshowed that there is a maximum stress in contact surfaces of\r\nindentations and also in place of changing diameter. Safety factor\r\nvalue is low in parts of the shaft and this increases the probability of\r\nfailure at these points. To improve the conditions with the least cost\r\nand an approach of product improvement, using alternative alloy is\r\nimportant.","references":null,"publisher":"World Academy of Science, Engineering and Technology","index":"Open Science Index 96, 2014"}
