Abstract

A torque assisting device, a method and a mammary machine are provided. According to an example, the torque assisting device includes a rotating mechanism, a fixing cylinder and an axially elastic force-applying mechanism. The rotating mechanism is provided with a load. An end surface of the fixing cylinder is provided with a motion trajectory having an inclination angle and the fixing cylinder is connected with the force-applying mechanism. The rotating mechanism is abutted on the motion trajectory at one end thereof and rotates about an axis of rotation along the motion trajectory. The inclination angle of the motion trajectory is set according to a torque generated by the gravity of the load. By setting the motion trajectory with an inclination angle and the fixing cylinder, torque associated with rotation angle of the centre of gravity of the load may be output passively, counteracting the torque generated by the load's gravity.

Description

technical field [0001] The present application relates to the field of torque balance, in particular to a torque boosting device, method and mammary gland machine in medical equipment. Background technique [0002] When a rigid load rotates around an axis, there may be a case where the gravity of the load will generate a torque because the center of gravity of the load does not coincide with the axis of rotation. Both the magnitude and direction of this torque vary with the load's rotation angle and rotation phase. see figure 1 , the mass of the load is m, the radius from its center of gravity to the axis of rotation is L, and the angle between the real-time radius of the rotation of the center of gravity of the load and the vertical direction is α, then the torque M generated by the gravity of the load G : [0003] m G =m×g×L×sinα (1) [0004] where g is the acceleration due to gravity. [0005] From the formula (1), it can be concluded that the magnitude of the torqu...
