Abstract
A bearing locking mechanism capable of surely preventing dropping of a bearing, without increasing size of a transmission, is provided. In a bearing locking mechanism in which a bearing G3c of a rotating body G3b axially supported by a transmission case 7 rotationally is prevented from dropping from the transmission case 7, a transmission 1 is equipped with a brake B1 provided so as to be adjacent to the bearing G3c, the brake B1 is equipped with a fixing member B1a to be fixed to the transmission case 7, and the bearing G3c is prevented from dropping from the transmission case 7 by the fixing member B1a engaging with a side surface in an axial direction of the bearing G3c.
Claims2
A transmission comprising:
- a transmission case;
- a bearing designed to support a rotating body pivotally on the transmission case;
- and
- a planetary gear mechanism;
- a brake configured to releasably lock one of a plurality of elements of the planetary gear mechanism, wherein
- the brake is positioned adjacent to the bearing,
- the brake comprises a fixing member fixed to the transmission case, and
- the fixing member is engaged with a side surface of the bearing in an axial direction of the bearing,
- wherein the rotating body is formed with a lubricating oil hole, and a lubricating oil is supplied to an outer peripheral surface of the rotating body from the lubricating oil hole, and
- the fixing member is formed with a guide portion,
- the guide portion is a curved notch formed at a bearing side of an inner circumferential surface which forms a piercing hole into which the rotating body of the fixing member is inserted, and
- the curved notch is configured to guide the lubrication oil supplied to the outer peripheral surface of the rotating body to the bearing.
