The shift gear 9 is integrally formed with a large-diameter gear 9a that selectively meshes with the gear 4 and a small-diameter gear 9b that selectively meshes with the gear 5, and has a thick groove 9C carved on the outer periphery of the center portion. There is.

，９ｂの選択噛合を行う。A hydraulic cylinder 10 is fixed to the side surface of the box l in parallel with the spline shaft 7, and the tip of a shifter 13 fitted to a piston rod 12 integrated with a piston 11 fitted into the hydraulic cylinder 10 is engaged with the groove 9C. By switching the pressure oil, the shift gear 9 is moved to the gears 4, 9a or the gear 5.
, 9b are selectively engaged.

d is removed from the side surface 4a of the gear 4, and when the shift gear 9 moves to the left and the small diameter gear 9b and the large diameter gear 5 mesh, the shift gear 9 overshifts as shown in FIG. The meshing side end surface 9e of the gear 5 is removed from the side surface 5a of the gear 5, and at the same time, the meshing side end surface 5b of the gear 5 is removed from the side surface 9f of the gear 9b.

歯車９が右側に移動し歯車９ｂが歯車５と噛合される。Operation Now, pressure oil is supplied to the front chamber of the hydraulic cylinder 10, the piston 11 is at the rear end position, the piston rod 12, the shifter 1
The shift gear 9 is set to the left side position through the gear 3, and the gear 9a and the gear 4, which is integral with the drive shaft 2, are in mesh with each other. When the drive shaft 2 is rotated by a motor (not shown), the spline shaft 7 rotates while being decelerated by the tooth ratio, but since the end surface 9d, which is easily damaged, is removed from the meshing surface, the spline shaft 7 rotates quietly without noise. Next, the rotation of the motor is stopped, the pressure oil is switched and the pressure oil is supplied to the rear chamber of the hydraulic cylinder IO, and the piston rod 12. The shift gear 9 moves to the right via the shifter 13, and the gear 9b meshes with the gear 5.
このときの噛み合いの状態は歯車９ｂ、５のそれぞれの
噛み合い側端面９ｅ。The meshing state at this time is the meshing side end surfaces 9e of the gears 9b and 5, respectively.

る。5b is overshifted so that it is removed from the meshing surface. When the motor rotates and the drive shaft 2 rotates, the spline shaft 7 is sped up by the tooth ratio of the gear 5.9b and rotates at high speed, but at this time as well, the end surface 9e is easily damaged.
, 5b are not engaged, so it rotates quietly without noise.

の改善が実現される効果を有する。Effects As detailed above, in the present invention, the shift gear is overshifted to remove the easily damaged end surface of the meshing side from the meshing surface during meshing, so even if the end surface of the meshing side is damaged when the shift gear moves, it can be avoided. This eliminates the cause of noise during rotation, reduces the noise of the two mechanical devices, and has the effect of improving the working environment.
