Abstract
A transmission gear mechanism having a plurality of drive gears and a shiftable driven gear. Eccentric gears are provided between the drive gears to smoothly transfer the driven gear from one drive gear to the next during shifting without interrupting the power transmission. Bearing surfaces are provided to bias the driven gear into contact with the drive and eccentric gears at all times to maintain power transmission.
Claims8
A transmission gear mechanism comprising:
- drive means including a drive shaft and drive gears of gradually differing diameters mounted for rotation on said drive shaft;
- driven means including a driven shaft, parallel to and movable toward and away from said drive shaft, and a driven gear mounted on said driven shaft to be movable axially therealong and to be kept in mesh with said drive gears, selectively;
- means for so moving said driven gear along said drive shaft to shift it from one drive gear to the next, wherein said drive means comprises transfer means to assist the driven gear in moving from one drive gear to the next during said shifting;
- and
- means to hold the driven gear in mesh with the drive means at all times.
