Chimerism.

接著,針對第1可換齒體120與第2可換齒體130之安裝方法說明。Next, a method of attaching the first interchangeable tooth body 120 and the second interchangeable tooth body 130 will be described.

首先,鏈輪本體110之可換齒裝著部112插入第1可換齒體120之被裝著部122之插入槽部125,使第1可換齒體120之被裝著部122卡合於鏈輪本體110之可換齒裝著部112,使第2孔123之位置對應於第1孔111之位置,使第1可換齒體120對應於鏈輪本體110之多角形之外周緣114之一邊並壓接此一邊。First, the interchangeable tooth attachment portion 112 of the sprocket body 110 is inserted into the insertion groove portion 125 of the attached portion 122 of the first interchangeable tooth body 120, and the attached portion 122 of the first interchangeable tooth body 120 is engaged. The position of the second hole 123 corresponds to the position of the first hole 111 in the interchangeable tooth attachment portion 112 of the sprocket body 110, so that the first interchangeable tooth body 120 corresponds to the outer periphery of the polygonal shape of the sprocket body 110. One side of 114 is crimped to this side.

其次,將錐形螺栓140插入第2孔123與第1孔111,將第1可換齒體120安裝於鏈輪本體110。Next, the tapered bolt 140 is inserted into the second hole 123 and the first hole 111, and the first interchangeable tooth body 120 is attached to the sprocket body 110.

此時,第2孔123之位置係設為成為比第1孔111之位置往鏈輪本體110之徑方向之外側稍微偏離之位置。At this time, the position of the second hole 123 is set to be slightly shifted from the position of the first hole 111 to the outer side in the radial direction of the sprocket body 110.

此時,透過於錐形螺栓140之插入方向設有狹縫之公知之套筒150與墊片170以錐形螺栓140與螺帽160鎖緊, 將第1可換齒體120固定於鏈輪本體110。At this time, the known sleeve 150 and the spacer 170, which are provided with slits through the insertion direction of the tapered bolt 140, are locked by the tapered bolt 140 and the nut 160. The first interchangeable tooth body 120 is fixed to the sprocket body 110.

以錐形螺栓140與螺帽160鎖緊之套筒150於與插入方向交差之方向變形,故在第1可換齒體120與鏈輪本體110之間有相對之力作用以使第2孔123之位置與第1孔111之位置成為相同之位置。The sleeve 150 locked by the tapered bolt 140 and the nut 160 is deformed in a direction intersecting with the insertion direction, so that a relative force acts between the first interchangeable tooth body 120 and the sprocket body 110 to make the second hole. The position of 123 is the same as the position of the first hole 111.

若換言之,於第1可換齒體120有往鏈輪本體110之徑方向中心側之力作用。In other words, the first interchangeable tooth body 120 has a force acting toward the center side in the radial direction of the sprocket body 110.

藉此,第1可換齒體120之插入槽部125之底與鏈輪本體110之外周緣114確實面接觸,故可將第1可換齒體120相對於鏈輪本體110於徑方向精度良好地定位。Thereby, the bottom of the insertion groove portion 125 of the first interchangeable tooth body 120 is in surface contact with the outer peripheral edge 114 of the sprocket body 110, so that the accuracy of the first interchangeable tooth body 120 with respect to the sprocket body 110 in the radial direction can be achieved. Good positioning.

同樣地,使第2可換齒體130與第1可換齒體120鄰接,鏈輪本體110之可換齒裝著部112插入第2可換齒體130之被裝著部132之插入槽部135,使第2可換齒體130之被裝著部132卡合於鏈輪本體110之可換齒裝著部112。Similarly, the second interchangeable tooth body 130 is adjacent to the first interchangeable tooth body 120, and the interchangeable tooth attachment portion 112 of the sprocket body 110 is inserted into the insertion groove of the attached portion 132 of the second interchangeable tooth body 130. The portion 135 engages the attached portion 132 of the second interchangeable tooth body 130 with the interchangeable tooth mounting portion 112 of the sprocket body 110.

之後,使第2孔133之位置對應於第1孔111之位置,將錐形螺栓140插入,將第2可換齒體130安裝於鏈輪本體110。Thereafter, the position of the second hole 133 is set to correspond to the position of the first hole 111, the tapered bolt 140 is inserted, and the second interchangeable tooth body 130 is attached to the sprocket body 110.

此時,僅將第2可換齒體130相對於第1可換齒體120從鏈輪本體110之徑方向外側往中心側插入,卡合突條124便嵌合於被卡合槽部134。At this time, only the second interchangeable tooth body 130 is inserted into the center side from the outer side in the radial direction of the sprocket main body 110, and the engagement protrusion 124 is fitted to the engaged groove portion 134. .

如上述操作,可容易安裝至最後之一個。As described above, it can be easily installed to the last one.

假如,為使於周方向突出之凸部與於周方向凹陷之凹部嵌合之構造之場合係將最後之一個從徑方向外側往中心側插入而安裝為困難,但與此種構造比較,以本發明係可 容易安裝至最後之一個。In the case of a structure in which the convex portion protruding in the circumferential direction and the concave portion recessed in the circumferential direction are fitted, it is difficult to insert the last one from the outer side in the radial direction toward the center side, but compared with such a structure, The invention is Easy to install to the last one.

此外,卡合突條124之外周側卡合寬度W1、卡合突條之內周側卡合寬度W2、被卡合槽部之外周側被卡合寬度W3、卡合突條之內周側卡合寬度W4之關係上,若先將所有之第1可換齒體120安裝於鏈輪本體110後再將第2可換齒體130安裝於鏈輪本體110,可容易安裝至最後之一個。Further, the outer circumferential side engagement width W1 of the engagement projection 124, the inner circumferential side engagement width W2 of the engagement projection, the outer circumferential side engagement width W3 of the engaged groove portion, and the inner circumferential side of the engagement projection. In the relationship of the engagement width W4, if all of the first interchangeable tooth bodies 120 are first attached to the sprocket body 110 and then the second interchangeable tooth body 130 is attached to the sprocket body 110, the last one can be easily attached. .

在將第1可換齒體120與第2可換齒體130卸除時係若先將所有之第2可換齒體130從鏈輪本體110卸除後再將第1可換齒體120卸除,可容易卸除至最後之一個。When the first interchangeable tooth body 120 and the second interchangeable tooth body 130 are removed, all of the second interchangeable tooth bodies 130 are first removed from the sprocket body 110, and then the first interchangeable tooth body 120 is removed. Dismounting can be easily removed to the last one.
