Claims

[Scope of utility model registration request]

A rotating shaft made of a non-magnetic material to which a special magnetic annular plate is fixed and rotated, a cylindrical shaft made of a non-magnetic material with a bearing for the rotating shaft housed in the center of the bottom disk, and a female thread provided on the inner periphery. A cylindrical rod made of a non-magnetic material with a circular magnet housed and fixed on its inner periphery, a male thread provided on its outer periphery, and a plurality of round holes drilled on the concentric circle of the bottom disc is connected to the magnetic pole surface of the circular magnet. and the special magnetic annular plate are screwed into the cylinder A so that they face each other with a substantially parallel magnetic gap in between. Two sliding dowel pins are fixed to the bottom disc by pushing them into two of the plurality of round holes in the cylindrical hole, and the bearing of the rotating shaft is housed in the center.
It consists of a cylinder (C) made of a non-magnetic material whose inner circumference can smoothly fit and rotate on the outer circumference of the cylinder (A), and two types of set screws fix the cylinders (A) and (B) together. A rotary brake characterized in that it is integrally configured.
