Abstract:A C-arm-swinging structure is proposed in this paper for the mammography X-ray diagnostic equipment based on the wire transmission. The DC (Direct Current) motor with a worm gear speed reducer is deployed in this structure so as to realize shaft rotation of imaging trays. Moreover, the electromagnetic brake is used to make a switchover between the overall swinging of the C-arm and imaging trays and the independent swinging of the C-arm. The wire rope is always running at the state of desired preload in the wire drive system. Since combination of three-level fixation and rough and fine adjustment are applied in the structure, which ensures the safe performance and raises the adjustment accuracy of the system. As a consequence, this system has become tightly-structured and easy-to-adjust. The structure has demonstrated its advantages in the tightened structure, simple drive and high efficiency over conventional C-arms.
