Claims

[Scope of utility model registration request]

(1) A casing that houses and supports a variable speed rotation mechanism and a lubricant for the variable speed rotation mechanism, and rotatably supports at least the load side of the output shaft of the variable speed rotation mechanism via a self-aligning bearing; an inner circumferential surface formed on the body to have approximately the same diameter as the self-aligning bearing fitting part and protruding in the axial direction from one end surface of the self-aligning bearing to the inside of the casing, and fitted to the output shaft; and an oil draining member having an outer diameter surface facing the inner peripheral surface with a small gap therebetween, and one end surface of the outer peripheral part facing one end surface of the outer ring of the self-aligning bearing with a small gap therebetween. gearbox.

(2) Both end surfaces of the flat portion of the oil cutting member are in contact with one end surface of the final rotating gear such as the stepped portion of the output shaft, and the outer diameter surface and one end surface of the annular bent portion formed on the outer edge are 2. The transmission according to claim 1, wherein the transmission device is opposite to the inner circumferential surface of the body and one end surface of the self-aligning bearing.

(3) Request for registration of a utility model characterized in that both end surfaces of the fitting portion of the oil draining member with the output shaft are in contact with one end surface of the inner ring of the self-aligning bearing and one end surface of the final rotating gear, respectively. The transmission according to the range 1 or 2.
