しなければならず不慣れな作業となつている。 Some rotaries with such a structure rotate the rotary part forward and backward by swapping the side transmission case with a built-in chain left and right. According to this, the side frame is on the right side, and this right side is placed along the cultivated land side. Although they had been working together, the left side had to be on the cultivated land side, which is an unfamiliar task.

ことを特徴とする。 The present invention was devised in view of the actual situation, and in a rotary machine in which a power case with a built-in bevel gear mechanism is provided at the top of the frame, the bevel gear mechanism is located on the output shaft side compared to the bevel gear on the power receiving shaft side. The bevel gears are engaged so that they can be changed in forward and reverse directions, and the bevel gear on the output shaft side has a boss part that inserts and supports the output shaft so that it can be inserted and removed, and the female spline and the straight shaft part of the output shaft are supported on the boss part. The output shaft has a male spline connected to the female spline of the boss part, and a male spline on the shaft end side of the male spline as a common axis with the output shaft axis. The spline has a supporting portion having a smaller diameter than the male spline, and is removably fitted into the supporting portion and the fitting portion when the male and female splines are joined and the supporting portion and the fitting portion face each other inside and outside in the radial direction. It is characterized by having a cylindrical bearing.

To change from normal rotation in the diagram to reverse rotation in Figures 3 and 4,
The engagement position of the bevel gear 11 with respect to the bevel gear 9 is changed, and the boss portion 1 of the bevel gear 11 is changed.
Attachment and detachment of the cylindrical bearing 17 in step 3 and the support section 1
It is possible to prevent the spline from rattling through the fitting support 8, and the pawl shaft 7 can be rotated in the forward and reverse directions without changing the transmission case 4 from side to side. It is possible to work on the cultivated land side.

同じにできる利点がある。 In this invention, the output side bevel gear of the bevel gear mechanism inside the power case is engaged with the input side bevel gear so that the forward and reverse rotations can be changed freely, so that forward and reverse rotation is possible without changing the side transmission case left and right. Since the transmission case and side frame are standardized for both forward and reverse rotation, there is an advantage that the plowing operation can be performed in the same manner.
