<p>A railway car gearing (100) obtained by housing in a gearbox (5): a large gear (1), which is secured to an axle (2) that is provided on a bogie frame, meshes with a small gear (3) and transmits a rotational force; and the small gear (3). A dehydrating device (12), which removes moisture contained in the lubricating oil (11) inside the gear box (5), is disposed on the inner surface of the gear box (5) in the direction of the circumference of the large gear (1). The dehydrating device (12) is disposed in an open space (a1, a2) formed above a line, which is an extension of a line that ties the axle (2) and the small gear axis (4), or is disposed in an open space (b1, b2) formed below the line, which is an extension of the line that ties the axle (2) and the small gear axis (4).</p> |
