Claims

[Scope of utility model registration request]

an input shaft rotatably supported on the front wall of the transmission housing via a tapered roller bearing;
The input shaft has an output shaft, the front end of which is rotatably supported via a pilot bearing in a hollow portion formed at the rear end of the input shaft, and which is disposed coaxially with the input shaft. A lubrication structure for a gear type transmission, wherein a lubricating oil introduction passage is formed that communicates with the hollow portion from the front outer peripheral portion of the bearing support portion and supplies lubricating oil to the pilot bearing, the outer race of the tapered roller bearing. and an inner race is disposed so as to expand in diameter toward the front end of the input shaft, and a front cover disposed on the front wall and covering the front surface of the front wall; and an inner race of the tapered roller bearing. A lubrication structure for a gear type transmission characterized by a thrust bearing installed between the race and the race.
