SHAFT MOUNTING STRUCTURE OF FARM WORKING MACHINE

PROBLEM TO BE SOLVED: To perform the reliable mounting of a rotary shaft 26 free from the occurrence of play by fastening the rotary shaft 26 axially immovably by a bolt member 38 and preventing the loosening of the bolt member 38, and effectively prevent the fall-out of a snap ring 51 by applying a component force in the direction of the center of the rotary shaft 26a on the snap ring 51 by tapered parts 52 even when a pull-off force in an axial direction is applied to one rotary shaft 26a to perform reliable holding free from the pull-off of the rotary shaft 26a by effectively preventing the fall-off of the snap ring 51. SOLUTION: A shaft mounting structure comprises the bolt member 38 fixing the position of the rotary shaft 26 to a bearing member 20 by screw coupling; a locking member 43 to regulate the rotation of the bolt member 38; and a drop-off preventing member 44 to prevent the fall-off of the locking member 43 from the bolt member 38. Further, it is provided with the snap ring 51 fixed on a rotary shaft 26a and a shaft fit-in member 28 to make contact with the snap ring 51 and regulate the pull-off of the rotary shaft 26a. Parts between the shaft fit-in members 28 of the snap ring 51 are formed into the tapered parts 52. COPYRIGHT: (C)2004,JPO
