Claims

[Scope of utility model registration request]

A large number of spline teeth protruding from the outer peripheral surface of the transmission shaft are fitted with a large number of spline grooves recessed into the inner peripheral surface of the boss of the gear, and the transmission shaft has an oil passage running through its center. , an inner oil hole communicating the oil passage with the outer peripheral surface of the transmission shaft is provided, and the gear is provided with an outer oil hole communicating the inner oil passage with the outer peripheral surface of the gear,
In a spline combination of a transmission shaft and a gear, a small number of spline teeth arranged at equal intervals in the circumferential direction of the transmission shaft among the large number of spline teeth are made into wide spline teeth having a wider width in the circumferential direction than other spline teeth, A transmission shaft characterized in that an inner oil hole is opened at the top surface of the wide spline tooth, and an outer oil hole is opened at the bottom surface of the wide spline groove formed on the gear so that the wide spline tooth fits therein. and gear spline combinations.
