PURPOSE:To improve switching operability by installing bearings, which support speed change gears, in a couple of bearing boxes fitted to a gear box eccentrically and rotatably, and by alternating an intermediate shaft and the speed change gears manually or electrically. CONSTITUTION:A high-speed shaft 11 is supported bearings 13a and 13b fitted to a gear box 12, and a low-speed shaft 15 is supported by bearings 17a and 17b. Bearing boxes 18a and 18b have incorporated bearings 17a and 17b and extents A of eccentricity, and are fitted rotatably to the gear box 12 through bearings 19a and 19b. In this case, when power is inputted from the input terminal 11a of the high-speed shaft 11 and outputted from the output terminal 11b, an intermediate shaft has no loss of gear engagement, and a handle for operation is changed over manually or electrically to display the functions of speed change gears while improving the switching operability. |
