In the rotor type pitching machine the rotor width fine adjustment device

摘要

PURPOSE: To adjust the width between rotors when the rotors are worn by screwing a minor adjustment shaft, for which left and right reverse screws are formed at a screwing section, to the minor adjustment shaft attaching part of main both rotary shaft and correcting the gap of main rotary shafts through the rotations of the minor adjustment shaft. CONSTITUTION: A minor adjustment shaft attaching part 14 is formed and fixed between a slider 13 and upper and lower guides 11 at a position corresponding to a pair of two guides 11 on the surface of an attaching plate 12 on the opposite side of main rotary shafts 9. The slider 13 is mounted so as to be freely slid while being sandwiched between the guides 11 so that the attaching plate 12 can be slid along the guides 11 and the main rotary shafts 9 mounted on the attaching plate 12 can be slid as well. Left and right reverse female screws are formed at the screwing sections of minor adjustment shaft attaching parts 14 and 15. In the state of requiring minor adjustment, a bolt 7 for fixture is loosened and when the minor adjustment shaft 17 is rotated, the minor adjustment shaft attaching parts 14 and 15 screwed with this shaft are moved to be mutually proximate on left and right sides or to be mutually separated in the rotating direction.
