Description of the Related Art As a vertical gear reduction (speed-up) device for general industrial machines, for example, as shown in FIG. 4, a vertical gear reduction device using a planetary gear mechanism is known. This vertical gear reduction device has an input shaft 2 having a sun gear 1 integrally or separately provided at a shaft end thereof, and an output shaft 3 meshing with the sun gear 1.
A plurality of planetary gears 4 held rotatably and revolvably by an internal gear 5 and an internal gear 5 meshed with each planetary gear 4 on an inner peripheral surface thereof
And a cylindrical housing 7 fixed to a fixing member 6 such as a motor case by an appropriate fixing means.

A plurality of (the same number as the planet gears) holding shafts 9 are provided integrally or separately, and the holding shafts 9 rotatably hold the planetary gears 4 via bearings 10.

An outer race 11, an inner race 12 having a double row of raceways formed on the outer peripheral surface, a double row barrel-shaped roller 13 for transferring between the raceways of the outer and inner races 11 and 12, and rollers 13 are held at equal circumferential intervals. The retainer 14 is a main component. This bearing 10
Rotates the planetary gear 4 on the holding shaft of the output shaft by fitting and fixing the planetary gear 4 on the outer peripheral surface of the outer ring 11 and fitting and fixing the inner ring 12 on the holding shaft of the output shaft (not shown). Hold as possible.

下につながる可能性がある。As described above, lubrication of the bearing 10 used for the planetary gear 4 of the vertical gear reduction device is performed by dropping or spraying oil from a fueling nozzle 15 fixed to the housing 7. However, since the planetary gear 4 revolves, in the bearing 10 of the conventional structure shown in FIG. 5, the supplied lubricating oil is hardly splashed off by centrifugal force and flows into the bearing, and the lubrication performance inside the bearing is concerned. Therefore, there is a possibility that the durability of the bearing is reduced.
