This invention discloses an induction hardening device for machining bevel gear shaft workpieces, belonging to the technical field of heat treatment processing equipment. The device includes a housing with a partition inside. A multi-station turntable is located above the partition, and a frame is connected to the top of the turntable. Along the circumferential direction of the multi-station turntable, there are bevel gear preheating stations and overall heating stations. Each station has a corresponding lower center assembly, and an upper center assembly is located above each station. The upper center assemblies are mounted on the frame via an elastic floating mechanism and are coaxially engaged with the lower center assemblies. This invention achieves uniform hardening of bevel gear workpieces through a differentiated station layout and adapts to the thermal deformation of the workpiece through the elastic floating mechanism, effectively improving the coaxial arrangement and mutual cooperation in the direction. This invention achieves differentiated heat treatment of bevel gear workpieces, ensuring the consistency of the hardened layer depth and adapting to the thermal expansion and contraction deformation of the workpiece, thus avoiding workpiece damage.

The invention relates to the technical field of fermentation equipment, and discloses a motor mounting structure based on a fermentation tank, the motor mounting structure is used for connecting a stirring shaft with a motor, the upper end of the stirring shaft is provided with a shaft seat fixed with a cover body, the stirring shaft coaxially penetrates through the shaft seat, and the stirring shaft comprises a connecting seat, a motor seat and a torsion connector; the lower end of the motor base is provided with a plurality of insertion rods distributed parallel to the motor shaft, and the upper end of the connecting base is provided with a plurality of insertion holes matched with the insertion rods. The torsion connector comprises an upper connecting assembly and a lower connecting assembly, the lower connecting assembly is fixedly connected with the upper end of the stirring shaft, and the upper end of the upper connecting assembly is fixedly connected with a motor shaft; when the inserting rod on the motor base is connected with the inserting hole in the connecting base in an inserted mode, the lower end of the upper connecting assembly and the lower connecting assembly are coaxially connected in an inserted mode to form synchronous rotation. The motor has the beneficial effect that the motor is convenient to disassemble and assemble.
