(Illustrated in FIG. 2) and the like are provided.

An oil distribution board 8 having a large number of through holes 8a is arranged in the upper portion of the gear box 1. A drive shaft of a rotary oil pump 9 is integrally rotatably connected to the rotary shaft 6. The suction port of the oil pump 9 is connected to the other end of a suction pipe 11 having one end inserted into the oil tank 2 and an oil filter 10 connected midway, and one end of the outlet corresponds to the upper surface of the oil distribution board 8. Oil supply pipe 12 arranged at the position
Is connected to the other end.

As shown in FIG. 2, on the oil tank 2, a main frame 13, which constitutes the peripheral wall of the gear box 1, both side frames 14 and a front frame 15 are fixed by bolts 16 to form a housing portion whose front surface is open. In addition, an inner door 17 that covers the opening is attached to one side frame 14 by a hinge (not shown) so as to be openable and closable to form a hermetically sealed gear box 1. Also, the oil tank 2
A through hole 2a covered with a filter 2b is formed on the top plate of the above, and a sub-frame 18 for assembling the gear ring G in a state of straddling the through hole 2a is fixed by a bolt 16.

Grooves 19a, 19 are formed on the outer periphery of the front side and both sides of the oil tank 2.
The oil receiving portion 19 having b is bulged. Grooves 19a provided on both sides of the oil tank 2 are formed so as to be inclined downward toward the front side, and a groove 19b provided on the front side of the oil tank 2 in communication with the groove 19a extends toward the center of the front side of the oil tank 2. It is formed so as to descend and incline. Fifth
As shown in the figure, the groove 19b communicates with the groove 20 formed in the top plate at the center of the front side of the oil tank 2, and the top plate penetrates the top plate to connect the groove 20 to the inside of the oil tank 2.
