The radius of the driving disc of the friction gear is 10 cm. Find the gear ratio of this gear if the radius of the driven disc is 20 cm.
Task data: R1 (radius of the driving disk of the given friction gear) = 10 cm; R2 (radius of the driven disk) = 20 cm.
The gear ratio of a given friction gear can be determined by the formula: u = D2 / (D1 * (ε – 1)) ≈ D2 / D1 = R2 / R1.
Let’s perform the calculation: u = 20/10 = 2.
Answer: The gear ratio of the given friction gear is 2.
