Zusammenfassung: | PROBLEM TO BE SOLVED: To suppress the loosening of bolts while suppressing an increase of the number of part items, in a differential structure for fastening a differential case and a ring gear with the bolts.SOLUTION: A differential structure fastens a differential case 2 which has annular fastening faces 5a, 6a, and in which a plurality of annular bolt holes 5b, 6b extending in parallel with an axial direction are formed at the fastening faces 5a, 6a, respectively, and a ring gear 3 with bolts 8 which are inserted into the bolt holes 5b, 6b with the fastening faces 5a, 6a as mating faces. The fastening face 5a of the differential case 2 and the fastening face 6a of the ring gear 3 are tapered faces which are inclined to one side in the axial direction with respect to axial orthogonal directions of the bolts 8.SELECTED DRAWING: Figure 1
【課題】デフケースとリングギヤとをボルトで締結するディファレンシャル構造において、部品点数の増加を抑えつつ、ボルトの緩みを抑制する。【解決手段】各々円環状の締結面5a,6aを有し、締結面5a,6aに円環の軸方向と平行に延びる複数のボルト孔5b,6bがそれぞれ形成された、デフケース2とリングギヤ3とを、これらの締結面5a,6aを合わせ面とし、且つ、これらのボルト孔5b,6bに挿通されたボルト8で締結するディファレンシャル構造である。デフケース2の締結面5aおよびリングギヤ3の締結面6aが、ボルト8の軸直角方向に対して軸方向一方側に傾斜したテーパ面である。【選択図】図1 |
