IPC: F16D1/04
Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To provide a gear-head attaching mechanism having a simple structure and easily assembled work. SOLUTION: In a housing 2 of a gear head 1, a fastening lateral hole 21 is bored to make therethrough drive-able a fastening bolt 8 for fastening a joint portion 7 of an input pinion axis 5 to a motor shaft 11, which are inserted into the inside of the housing 2. By so adjusting the drive amount of the fastening bolt 8 that its head 82 is left in the fastening lateral hole 21 to bring it into a temporary fastening position, the motor shaft 11 is inserted in this state into a plug-in hole 6 of the input pinion axis 5.

Thereby, bearings for preventing the movement of the input pinion axis 5, etc., are not required to integrate them into a gear-head attaching mechanism. Also, the work for plugging the motor shaft 11 in the hole 6 can be performed simply.
