PROBLEM TO BE SOLVED: To obtain a body of revolution capable of easily replacing a follower wheel on site that needs no simultaneous processing of reamer holes on a drive shaft and the follower wheel during the replacement of the follower wheel while one component constitutes the follower wheel.SOLUTION: A body of revolution comprises: a reamer hole 35 formed on one edge face of a disc part 22 in an axial direction; a first/first pin 36 inserted into the reamer hole 35 so as to protrude from a first inclined plane 36a toward the axial direction of the disc part 22 as well as protrude the first inclined plane 36a to be held by the disc part 22; a pin storage hole 38 formed on the other edge face of a sheave 30 in an axial direction to accommodate the projection of the first pin 36; a female screw part 39 formed coaxially with the pin storage hole 38 so as to communicate between one edge side of the sheave 30 in an axial direction and the pin storage hole 38; a second pin 37 disposed in the pin storage hole 38 such that a second inclined plane 37a is brought into contact with the first inclined plane 36a; a push-in bolt 40 screwed in the female screw part 39 to push the second pin 37 to the first/first pin 36; and a mounting bolt 33 that fixedly tightens the sheave 30 to the disc part 22.

    【課題】この発明は、従動輪の交換時における駆動軸と従動輪へのリーマ穴同時加工を不要とし、かつ従動輪を1部品で構成し、現地で従動輪を簡易に交換できる回転体を得る。【解決手段】リーマ穴35が、円盤部22の軸方向一端面に形成され、第1第1ピン36が、第1傾斜面36aを円盤部22の回転方向に向けて、かつ第1傾斜面36aを突出するようにリーマ穴35に挿入されて円盤部22に保持され、ピン収納穴38が、綱車30の軸方向他端面に形成されて第1ピン36の突出部を収納し、雌ねじ部39が、ピン収納穴38と同軸に、綱車30の軸方向一端側とピン収納穴38とを連通するように形成され、第2ピン37が、第2傾斜面37aを第1傾斜面36aに接するようにピン収納穴38に配置され、押し込みボルト40が、雌ねじ部39に螺着されて第2ピン37を第1第1ピン36に押し付け、取付ボルト33が、綱車30を円盤部22に締着固定している。【選択図】図3
