Embodiment Construction

[0031] Below according to accompanying drawing and embodiment the present invention will be described in further detail:

[0032] This embodiment provides a tube rotation transmission mechanism in an X-ray photography system, which includes a motor 15, a reduction box 16, a synchronous belt 19, a gear shaft A 20, a gear shaft B 21, a bearing seat A and a bearing seat B;

[0033] The motor 15 and the reduction box 16 are integrally installed and fixed on the tube support 12 of the X-ray photography system;

[0034] One end of the synchronous belt 19 is installed on the output shaft of the reduction box 16, and the other end is installed on the gearless end of the gear shaft A 20;

[0035] The gear end of the gear shaft A 20 meshes with the gear end of the gear shaft B 21 to form a gear transmission;

[0036] The gear shaft A 20 is rotatably socketed on the bearing seat A;

[0037] The gear shaft B 21 is rotatably socketed on the bearing seat B;

[0038] The bearing seat A an...

Abstract

The invention discloses a bulb tube rotary driving mechanism in an X-ray photographic system. In the invention, the traditional driving mechanism is improved for driving through a synchronous belt and a gear, so that the phenomenon of overlarge reverse rotation clearance can be thoroughly eliminated. The bulb tube rotary driving mechanism in the X-ray photographic system, which can drive by adopting the synchronous belt and the gear, has the advantages of convenient installation and maintenance, attractive appearance, excellent functions, small mechanical clearance, easy realization of aligning the whole machine and more stable structure.

Description

technical field [0001] The present invention mainly provides a tube rotation transmission mechanism in an X-ray photography system, especially a tube rotation transmission mechanism using a synchronous belt and a gear transmission in the X-ray photography system. Background technique [0002] In the entire X-ray photography system, the light mechanism is the most important part of the Chinese formula. If the light is not well centered, the pictures taken will be bright and dark, which will affect the doctor's diagnosis. After the existing structure has been in operation for a period of time, the light mechanical alignment will deviate greatly. [0003] Most of the existing X-ray suspension frame photography system ball tube rotation transmission is: after the motor is decelerated by the gear box, it is then driven by a first-stage worm gear. In this way, the reduction ratio can be increased, and the real-time tube rotation Self-locking. However, the reverse gap between the...
