BEARING STRUCTURE AND SLIDE BEARING REPLACEMENT METHOD

To improve replacement work efficiency of a slide bearing.SOLUTION: A bearing structure 10 includes: a connection shaft 11 which is inserted into an insertion hole 1d of a first member 1 and insertion holes 2c of a pair of second members 2 located at both sides of the first member 1, and connects the members 1, 2 in a manner that the members 1, 2 can rotate relative to each other; cylindrical slide bearings 12 which are fitted on an outer periphery of the connection shaft 11 at the insertion holes 2c of the pair of second members 2 of the first member 1 and the pair of second members 2; and cylindrical sleeves 13, each of which is removably fitted in a space between an inner peripheral surface of the insertion hole 2c of each of the pair of second members 2 and an outer peripheral surface of the slide bearing 12 from the opposite side of the first member 1 side.SELECTED DRAWING: Figure 1 【課題】滑り軸受の交換作業効率を向上させること。【解決手段】軸受構造１０は、第１部材１の挿入孔１ｄおよび第１部材１の両側に位置する一対の第２部材２の挿入孔２ｃに挿入され、両部材１，２が相対的に回転可能に両部材１，２を連結する連結軸１１と、第１部材１および一対の第２部材２のうち、一対の第２部材２の挿入孔２ｃにおける連結軸１１の外周に嵌め込まれた円筒状の滑り軸受１２と、一対の第２部材２の挿入孔２ｃの内周面と滑り軸受１２の外周面との間に、第１部材１側とは反対側から抜き差し可能に嵌め込まれた円筒状のスリーブ１３とを備えている。【選択図】図１
