DIFFERENTIAL REDUCING GEAR MECHANISM WITH A TRIPLE TOOTHED CLUTCH

Click to enlargeClick to enlarge Description

Gears 5, 6 and 10 are rigidly attached together and rotate about fixed axis B. Gear 5 meshes with gear 4 which rotates about fixed axis C and is rigidly attached to gear 1. Gear 1 meshes with gear 2 which rotates about axis B and is rigidly attached to internal gear 3 and to gear 8. Gear 3 meshes with planet gears 7 which are connected by a turning pair to carrier 12. Carrier 12 rotates about axis B and is rigidly attached to gear 9. Planet gears 7 mesh with gear 6. Toothed clutch 13 slides along and rotates about axis A. Clutch 13 can be shifted into engagement so that its member, internal gear 11, engages the teeth of either gear 8, 9 or 10. When gears 11 and 8 are in engagement, as shown, speeds n₈ and n₅ of gears 8 and 5 (in rpm) are related by the equation n₅=n₈(z₂z₄)/(z₁z₅). When gears 11 and 9 are in engagement, speeds n₉ and n₅ of gears 9 and 5 are related by the equation n₅=n₉(1+(z₃/z₆))/(1+(z₁z₃z₅)/(z₂z₅z₆)). When gears 11 and 10 are in engagement, the speed n₁₀ of gear 10 equals the speed n₅ of gear 5. Thus n₅=n₁₀ where z₁, z₂, z₃, z₄, z₅ and z₆ are the numbers of teeth of gears 1, 2, 3, 4, 5 and 6.
