The invention discloses a high-transmission-ratio suspension shaft centrifugal supercharger which comprises a transmission unit, a fan supercharging unit and a cooling unit; the transmission unit is composed of a belt wheel, a planetary gear mechanism, a friction wheel group and a suspension mainshaft, the planetary gear mechanism comprises a sun gear and a planetary gear both installed in a gearbox, the sun gear and the belt wheel are in coaxial installation and rotate together, the planetary gears are distributed at the periphery of the sun gear in a 120 degree symmetric way and are meshed with and follow up the sun gear; the friction wheel group comprises friction wheels arranged in a sealed box and arranged coaxially with corresponding planetary gears; the suspension mainshaft generates contact friction with surfaces of the friction wheels and is driven to rotate together with the friction wheels; the cooling unit is used to pump out high-temperature lubricating oil in the gearbox and the sealed box, and lubricating oil is returned after cooling is performed. According to the invention, the supercharger is substantially improved in transmission precision and speed increasing ratio at a high speed range, and also possesses characteristics of long safe life, convenience for mounting, good heat dispersion performance, low noise and the like.
