Joint bearing transmission device and medical imaging device

Abstract

The embodiment of the invention provides a joint bearing transmission device and a medical imaging device. The joint bearing transmission device is applied to the medical imaging equipment and comprises a motor used for outputting power, a speed reducer connected with the motor, a speed reducer output end cover rotatably connected with the speed reducer and a changeover panel used for being connected to a load, wherein the speed reducer output end cover is provided with one of a key groove and a key; the changeover panel is provided with the other one of the key groove and the key; and the keygroove has the axial depth, the key has the axial thickness, the key groove is contained in the key, and therefore power output by the motor is transmitted to the changeover panel from the speed reducer output end cover through cooperation of the key groove and the key. The joint bearing transmission device and the medical imaging equipment have the beneficial effects of being high in rigidity and transmission precision, low in cost, simple in structure, convenient to install and the like.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of medical equipment, in particular to a joint bearing transmission device and medical imaging equipment. Background technique [0002] The more common medical imaging equipment is X-ray medical imaging equipment. Among them, large-scale real-time X-ray medical imaging equipment, such as vascular machine, can complete the cardiovascular, cerebrovascular, aorta, abdominal visceral blood vessels, pelvic blood vessels, extremities blood vessels, etc. Imaging of different blood vessels. It is valuable for diagnosing vascular lesions and tumor lesions in the above-mentioned various parts of the human body, and can also complete interventional therapy for lesions in various parts of the body. [0003] The main frame of the vascular machine used for interventional therapy is the main component of the vascular machine. figure 1 A schematic diagram of an existing vascular machine mainframe...

Problems solved by technology

[0005] Although the existing transmission mechanism is low in cost, simple in structure, and easy to operate, due to the large backlash of the planetary reducer in the existing transmission mechanism, a large torque needs to be borne between the output shaft and the load. In the process of emergency stop, it is easy to cause the system to shake, which affects the motion accuracy, and the longer the use time, the worse the accuracy
