TRANSMISSION WITH BRAKE

摘要

PROBLEM TO BE SOLVED: To provide a transmission with a brake capable of enhancing rotation of the brake and cooling efficiency of a fixed brake plate by effectively utilizing a lubrication oil for a speed reducer.

SOLUTION: A first oil reservoir chamber 61 for storing a large diameter bevel gear 30 and a second oil reservoir chamber 62 for surrounding a periphery of a driven shaft 27 such that a rear end surface of a driving shaft 26 is faced to it are provided provided on a transmission case 25. A communication port 65 for introducing an oil O scooped up by rotation of the large diameter bevel gear 30 in the first oil reservoir chamber 61 to the second oil reservoir chamber 62 is provided between the first and second oil reservoir chambers 61, 62. An inlet oil passage 70 for guiding the oil O introduced to the second oil reservoir chamber 62 to the driving shaft 26 and a spline fitting part of the rotation brake plate 42 is provided on the driving shaft 26.
