Abstract

The invention provides a torque assisting device and method and a mammary radiography machine. The torque assisting device comprises a rotary mechanism, a fixing drum and a force applying mechanism capable of axially telescoping. The rotary mechanism is provided with loads. A motion trail with an inclination angle is arranged on one end face of the fixing drum. The fixing drum is connected with the force applying mechanism. One end of the rotary mechanism abuts against the motion trail and rotates around a rotary shaft along the motion trail. The inclination of the motion trail is set according to torque generated by the gravity of the loads. According to the torque assisting device and method and the mammary radiography machine, by arranging the motion trail with a preset angle and the fixing drum, torque related to the load gravity rotary angle is output passively, torque generated by load gravity during rotation of the rotary mechanism around the shaft, is offset, and the load rotary balance is maintained.

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...
