| Title of Invention | ENGINE CRANKSHAFT SUPPORT STRUCTURE |
|---|---|
| Abstract | To miniaturize and lighten a main bearing that supports a crankshft. An inner race 28 forming a part of a main bearing 22 is losely fited into bearing seat 13 of a shft 12 and a direction of a thrust is fixed by a flange 31 of a timing sprocket 30 press fitted onto the shaft 12. The Outer diameter R1 of the timing sprocket 30 and the outer diameter R3 of the flange are respectively set so that they are smaller than the outer diameter R4 of the press fitted and fixed to the side of the main bearing 22 is press-fitted and fixed to the side of a left crankcase 20 and a roller 27 is intrgrated. When the shaft 12 enters the inside of the rollers 27, the timing sprocket 30 and the flange 31 pass the the inside of the roller 27 and the inner race 28 is fitted to the roller 27. Hereby, the inner diameter R2 of the inner race 28 can be made smaller than the outer diameter R1 of the timing sprocket 30. |
