DIFFERENTIAL BEVEL GEARING MECHANISM WITH GEARS OF DIFFERENT SIZE

Click to enlargeClick to enlarge Description

Bevel gear 1 is keyed to shaft a, rotates about fixed axis A-A and meshes with bevel planet gear 4. Bevel planet gears 4 and 2 are keyed to shaft c which is connected by turning pairs B and D to carrier 5. Carrier 5 is designed as housing d which rotates about axis A-A. Gear 2 meshes with bevel gear 3 which is keyed to shaft b and rotates about axis A-A. The speeds n₁, n₃ and n₅ of shafts a and b, and carrier5 (in rpm) are related by the equation n₅=(z₃z₄)/(z₃z₄-z₁z₂)n₃-(z₁z₂)/(z₃z₄-z₁z₂)n₁ where z₁, z₂, z₃ and z₄ are the numbers of teeth of gears 1, 2, 3 and 4.
