Description

Technical Field

[0001] The utility model relates to the technical field of rotating structures, in particular to a rotating gravity balancing structure. Background Art

[0002] The rotating gravity balance structure is specifically a rotating platform, which is used to rotate the device or person installed on the platform. The principle of overcoming gravity by rotation is to balance the gravity of the object by using the centrifugal force and centripetal force generated by the rotation of the object, so that the object has a relatively stable position. The centrifugal force refers to the force of the object in the rotating system away from the rotation axis along the radial direction. Its magnitude is related to the distance between the object and the rotation axis and the angular velocity. The centripetal force refers to the force of the object in the rotating system pointing to the rotation axis along the radial direction. Its magnitude is also related to the distance between the object and the rotation axis and the angular velocity. When the object rotates around the rotation axis, the centrifugal force and the centripetal force will interact and balance each other to form a stable equilibrium state.

[0003] After the corresponding instruments are installed on the surface of the rotating table, when the rotating table rotates, it is easily affected by the gravity of the instruments above, and thus it is easy to shake during rotation, affecting the overall effect of the rotating table.
