Abstract

The invention discloses a gearing device of a hanging digital-radiography system, which comprises a cable-wire turnplate shaft, a motor, a worm gear reduction box and a primary synchronous belt, and a transition shaft and a secondary synchronous belt as well, wherein, the shaft of the motor is connected with the worm gear reduction box, the primary synchronous belt surrounds one end of the transition shaft and the shaft of the worm gear reduction box, and the secondary synchronous belt surrounds the cable-wire turnplate shaft and the other end of the transition shaft. The gearing device of the hanging digital-radiography system utilizes the synchronous belts to carry out driving, and the transmission process is smooth and precise, thereby reducing the motional noise of the gearing device to the minimum; meanwhile, the characteristics of the self-lockable worm gear reduction box are utilized to improve the safety of the gearing device, and since no motor with electromagnetic brake is needed, the cost is saved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a transmission device of a suspension type digital radiography system. Background technique [0002] There are many forms of digital radiography system in structure, the common ones are U-arm structure and suspension frame structure, which are called U-arm type digital radiography system and suspension frame type digital radiography system respectively. Such as figure 1 and figure 2 As shown, the prior art suspension type digital radiography system includes a mounting beam 1, an imaging bed 2, a CCD detector 3, a column 4, a moving guide rail 5, a hanger 6, a ball tube and a light beam assembly 7, a fixed Guide rail 8, hanger beam 9. Wherein the moving guide rail 5, the hanger 6, the fixed guide rail 8 and the hanger beam 9 constitute the tube hanger of the digital radiography system. The installation of the digital radiography system with suspension frame structur...
