| description | To provide a tension adjustment device which has durability so that rotation moment is not generated at a support part even when receiving reaction force and is small in the number of part items, low in a cost, and easy in assembling to a power transmission device by an integrated simple constitution, and a grinder having the tension adjustment device.SOLUTION: A tension adjustment device 50 comprises a fixing member 51, an energization pulley 55, a slide member 56 and an elastic member 57. A center position of an energization reaction force which the energization pulley receives from a power transmission belt 42 is defined as a first center position D1, a center position of an energization force by which the elastic member energizes the slide member 56 is defined as a second center position D2, a position in which a guide member 53 of the fixing member 51 guides the slide member is defined as a guide position G, and a first distance L1 between the first center position and the second position is shorter than a second distance L2 between the first center position D1 and the guide position G.SELECTED DRAWING: Figure 4
【課題】反力を受けても、付勢用のプーリの支持部には回転モーメントが生じず耐久性を有するとともに、少ない部品点数、及び一体化された簡素な構成により、低コストで、且つ動力伝達装置への組み付けが容易である張力調整装置及び張力調整装置を備える研削盤を提供する。【解決手段】張力調整装置５０は、固定部材５１と、付勢用プーリ５５と、スライド部材５６と、弾性部材５７とを備える。付勢用プーリの回転軸線方向において、付勢用プーリが動力伝達ベルト４２から受ける付勢反力の中心位置を第一中心位置Ｄ１と定義し、弾性部材がスライド部材５６を付勢する付勢力の中心位置を第二中心位置Ｄ２と定義し、固定部材５１のガイド部材５３がスライド部材をガイドする位置をガイド位置Ｇと定義し、第一中心位置と第二中心位置との間の第一距離Ｌ１が、第一中心位置Ｄ１とガイド位置Ｇとの間の第二距離Ｌ２よりも短い。【選択図】図４ |
