Abstract: PURPOSE: To improve the stability of a travelling body at the time of windingly exchanging for a rubber crawler by eccentrically setting up the rotary shaft of an idler as much as a required dimension in vertical direction to the axial center of the idler shaft. CONSTITUTION: A vertical dimension from the axial centers O'-O' of an idler shaft 31 to an upper guide plane 32 of slide bearings 30, 30 to fit in the guide part of a track frame 25L is eccentrically set up as much as a required quantity δh than a vertical dimension from the axial centers O'-O' to a lower guide plane. After iron crawlers 9 are removed, and a pair of slide bearings 30 is turned over on both sides for reversedly attaching them, the iron crawler is windingly exchanged for a rubber crawler. The idler axial centers O'-O' is therefore located lower as much as Δh/2 than the horizontal center line Q-Q of a guide part 29, and the height position of the idler to a lower roller is thereby lowered.  Thus the longitudinal earthing length of the lower face of the rubber crawler increases to improve the stability of a travelling body at the time of windingly exchanging for the rubber crawler.

Abstract: PURPOSE:To provide a magnetic drum with a high precision by obtaining a magnetic pole length signal based on the rotational angle of a drum to be magnetized and simultaneously making the state of a current supplied to a magnetizing head a predetermined one, thereby reducing the variation of the magnetic pole length. CONSTITUTION:The output reference signal of a signal generator 3 in synchronism with a rotational angle is converted by a signal producing unit 4 to a pulse output corresponding to a required magnetic pole length P. And, a magnetizing magnetic head 6 is put in contact with a drum 1 to be magnetized which is rotating at a substantially fixed number of revolutions, and a current is caused to flow through a head 6. This current starts from zero and increases in its absolute quantity with the current direction being alternately inversed at a time corresponding to the magnetic pole length. Then, this current is held at a fixed current value for a predetermined time, and thereafter it is gradually decreased to zero. As a result, magnetization is completed.
