Document Type and Number:
Japanese Patent JPH0665903
Kind Code:
B2
Abstract:
A transmission for controlled equipment consists of a pair of intermediate gears in mesh with an input gear, another pair of intermediate gears in mesh with an output shaft and a pair of intermediate shafts, each connecting one of the intermediate gears engaged with the input gear and one of the intermediate gears engaged with the output gear, thus forming a pair of gear trains, wherein one of the intermediate gears is loosely mounted on one of the intermediate shafts and is also made fixable by a fixing means, the intermediate shaft and the intermediate gear in the loosely coupled condition are slightly turned in opposite directions so that the gear train made up of the input gear, the intermediate gears on one side and the output gear and the other gear train made up of the input gear, the intermediate gears on the other side and the output gear have no backlash between the gear teeth surfaces of the input gear and the intermediate gears with respect to the power driving directions which are opposite for the two gear trains, and then in that gear engagement condition the intermediate gear loosely mounted on the intermediate shaft is securely fixed to the intermediate shaft by the fixing means.
