Claims

[Scope of utility model registration request]

A gear box, first and second speed increasing gears meshing inside the gear box, a drive shaft to which the first gear is fixed, an output shaft to which the second gear is fixed, and an output shaft inside the gear box. supporting first and second bearings; an oil sump formed below the gear box;
An oil pan that surrounds the lower part of the first gear in close proximity to the outer periphery of the first gear and isolates the first gear from most of the oil in the oil sump, and a lubricating oil passage that communicates between the oil sump and the inside of the oil pan. In this gear speed increaser, a lubricating oil guide passage is integrally formed with the oil pan 5 and extends from the oil pan to the second gear along the rotational direction of the first gear and surrounds the outer circumference of the first gear. A guide vane is installed on the shroud that forms the oil guide passage so as to block part of the lubricant oil guide passage and allow some of the lubricant to flow toward the output shaft bearing. A lubricating device for a gear speed increaser, characterized in that an opening is provided as a passage for lubricating oil flowing toward the gear.
