Description
Gears 1 and 2 rotate about fixed axes A and B. Gear 1 has one tooth a. When driving gear 1 rotates continuously, driven gear 2 rotates only during the periods that tooth a engages a tooth b of gear 2. To each revolution of gear 1, gear 2 turns through an angle equal to ϕ=2π/z₂ where z₂ is the number of teeth of gear 2. For the given mechanism, ϕ=2π/5. To prevent unintentional rotation of gear 2 and to lock it during its dwell periods, gear 1 has concentric locking surface c which engages concave surfaces d on gear 2. When gear 1 rotates at uniform velocity, gear 2 has intermittent rotation. An impact occurs at the instant that teeth a and b come into engagement.
