Question

A speed reducer is rated at a maximum input speed of 2609 rpm and a maximum input power of 8 horsepower. The speed reduction ratio is 1:25, and the service factor is 1.15. What is the maximum input power?

Answer 1

Answer:

9.2 hp

Explanation:

Service factor is the ratio of the gearbox rated horsepower (or torque) to the application's required horsepower (or torque)

SF = Pₒ / Pᵢ

Pᵢ = Pₒ × SF

Pᵢ = 8 hp × 1.15

Pᵢ = 9.2 hp
