Beschreibung
Zusammenfassung:	The invention discloses a floating sealing device for a development machine, which comprises a first connection base (2) arranged on a rotary main shaft (1) of the development machine and a second connection base (4) arranged on a protective shell (3) of the development machine, wherein the first connection base (2) and the second connection base (4) have preset distance in the axial direction of the rotary main shaft (1); and the first connection base (2) is movably connected with the rotary main shaft (1) in the axial direction of the rotary main shaft (1). The floating sealing device overcomes the defect of error caused by mismachining tolerance, of the axial distance of the two connection bases, improves the operational performance, and simultaneously, reduces the requirements on machining and assembly of parts of the floating sealing device, so the machining cost is reduced. The invention also discloses the development machine with the floating sealing device.
