Description

Technical Field

[0001] The invention relates to the technical field of agitator equipment, and in particular to a stirrer frame with adjustable fulcrum. Background Art

[0002] In mixing equipment or other equipment that requires a reducer to drive, in order to ensure the stability of the transmission, it is necessary to specially weld the agitator frame. When the agitator shaft is long, the axial force, radial force, bending moment, etc. on the shaft of the transmission device are all borne by the reducer inner bearing. If the distance between the bearings is very close, it will lead to poor force distribution on the shaft. Under conditions with large forces, the service life of the reducer will be greatly reduced. The mechanical seal is easily damaged due to the large radial runout of the shaft, which reduces the stability of the safe operation of the agitator and is prone to production accidents. The existing agitator frame is only a simple welded bracket structure. When the transmission distance is too large, the coaxiality of the reducer shaft and the rotation center of the mixing device is difficult to ensure. Summary of the invention
