Claims

[Scope of utility model registration request]

An oil receiving shelf is provided on the inner surface of the casing of a tandem type reducer equipped with an interaxle differential to catch splashed oil from the divider gear, and the oil collecting shelf is formed in contact with the large diameter portion of the input shaft. a radial first oil passage communicating with the input shaft and having the oil reservoir chamber formed in the input shaft; an axial second oil passage communicating with the first oil passage; and a second oil passage communicating with the first oil passage. It communicates with the interaxle differential and the sliding contact portion between the input shaft and the divider gear, etc. through a third fluid passage in the radial direction, and the oil reservoir is formed at the end of the large diameter portion of the input shaft. In the lubrication structure of the tandem type reducer, in which a large number of oil introduction grooves are provided facing the chamber, inclined with respect to the axis, and communicating with the first oil passage, the input shaft is provided at a lower part of the oil reservoir chamber. A tandem type speed reducer, characterized in that a spiral wall is formed toward the center of the oil receiving shelf, and a notch is formed in the boss of the oil receiving shelf to communicate a concave side of the wall with the oil introduction groove. Lubricated structure.
