<P>PROBLEM TO BE SOLVED: To reduce the profile of an effective diameter as much as possible, since gears are brought into line contact with each other in the transmission method between gears using involute gears, it is difficult to reduce the surface pressure of the contact line, thus, the size of a first gear cannot be reduced by any possibility, and the effective diameter of a gear becomes considerably large when the transmission torque, shock, and coefficient are large. <P>SOLUTION: A root of a tooth profile of an involute gear is made thin. The root size is constituted to be maximum, and a gear of the tooth profile having a Mt. Fuji shape is manufactured. Further, a columnar roller is inserted between two gears, and is fitted so that it can rotate freely. <P>COPYRIGHT: (C)2012,JPO&INPIT |
