Abstract

The invention discloses a method for increasing the torque of a magnetic sealing device. A cone coaxial type magnetic sealing device of the following structure is applied; the cone coaxial type magnetic sealing device comprises a rotating shaft, a driving rotor, a driven rotor, an isolation sleeve, outer permanent magnets and inner permanent magnets, wherein shaft holes are respectively formed in the middle parts of the driving rotor and the driven rotor; the inner wall of the driving rotor and the outer wall of the driven rotor are conical surfaces, and the driving rotor covers the driven rotor; the isolation sleeve is arranged between the driving rotor and the driven rotor and is in a conical shape, the inner and outer walls of the isolation sleeve are parallel to the inner wall of the driving rotor, and gaps are formed among the driving rotor, the driven rotor and the isolation sleeve; a plurality of annular grooves are formed in the inner wall of the driving rotor and the outer wall of the driven rotor at intervals in a one-to-one corresponding mode; the permanent magnets are installed in the annular grooves. According to the method, the driving rotor and the driven rotor are designed into conical shapes, the grooves are respectively formed in the driving rotor and the driven rotor, and the permanent magnets are installed in the grooves, so that the torque magnetic sealing is increased.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering sealing, in particular to a method for increasing the torque of a magnetic sealing device. Background technique [0002] Magnetic seal, also known as magnetic coupler, uses the principle of permanent magnets to attract opposite sexes to realize non-contact transmission of torque. The metal isolation sleeve can achieve absolute sealing, so the magnetic seal has "zero leakage" and reduces vibration and noise, etc. advantage. The magnetic seal mainly includes three types of structures: end face magnetic seal, coaxial magnetic seal and parallel shaft magnetic seal. Among the three structures, the torque transmitted by the coaxial magnetic seal is the largest, but the transmitted torque is still small, which still cannot meet the demand for high torque in the transmission field. Therefore, improving the torque in the magnetic seal is of great significance for its successful application...
