The rotor of the CT bearing is connected with the turntable, and the stator of the CT bearing is connected with the bearing support frame. The X-ray bulb 13 and the X-ray detector 14 are oppositely arranged on the turntable. The turntable can rotate around the axis of the turntable under the driving of a transmission mechanism.
Fig. 2 is a schematic structural diagram of a transmission mechanism of a conventional CT machine. As shown in fig. 2, the transmission mechanism 15 includes: motor-pulley set 151, idler 152, tensioner 153 and belt 154. The belt 4 is respectively installed in cooperation with the motor-pulley set 151 and the turntable 121, and is used for driving the turntable 121 to rotate around its own axis under the driving of the motor-pulley set 151. The idler pulley 152 presses the belt 154 from the outside of the belt 154 so that the belt 154 forms a set wrap angle at the motor-pulley set 151 side. The tensioner 153 presses the idler pulley 152 by a spring to adjust the tension of the belt 154 so that the tension of the belt 154 is satisfied.
In addition, those skilled in the art are also working to find other transmission solutions.
SUMMERY OF THE UTILITY MODEL
In view of this, the embodiment of the present invention provides a CT machine transmission mechanism on the one hand, and provides a CT machine on the other hand, so as to realize the tension-free maintenance of the transmission mechanism and reduce the maintenance cost.
The embodiment of the utility model provides a drive mechanism of CT machine, CT machine includes the carousel; the transmission mechanism includes: the motor is a belt pulley group, an idler pulley and an elastic multi-wedge belt; the elastic multi-wedge belt is respectively matched with the motor-pulley group and the turntable; the idler pulley compresses the elastic poly-wedge belt from the outer side of the elastic poly-wedge belt so that the elastic poly-wedge belt forms a set wrap angle at the side of the motor-pulley set.
In one embodiment, the elastic v-ribbed belt comprises an elastic cable carcass and a hybrid rubber belt rib.
In one embodiment, the elastic cable carcass is a polyamide carcass.
The embodiment of the utility model provides an in provide a CT machine, including foretell drive mechanism.
It can be seen from the above-mentioned scheme that because the utility model discloses in adopt the elasticity polywedge to bring the transmission to come from motor-pulley group's drive power for the carousel to it is rotatory to drive the carousel around the axis of self, and the elasticity polywedge area has better elasticity than ordinary belt, under same extension length, its belt tension value change is very little, consequently need not to need a tensioning device to adjust the tensile force of belt like ordinary belt, consequently, overspeed device tensioner has been left out, the tensioning has been avoided in CT machine's effective life cycle and has been maintained, the maintenance cost is reduced. In addition, the elasticity is carried more and can also effectively absorb vibration and noise, reduces CT machine holistic noise value.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention is further described in detail by referring to the following embodiments.
Fig. 3 is a schematic structural diagram of a transmission mechanism of a CT machine according to an embodiment of the present invention. As shown in fig. 3, the CT machine includes a turntable 121; the transmission mechanism 16 includes: a motor-pulley set 161, an idler pulley 162, and an elastic v-ribbed belt 163.
The elastic poly-wedge belt 163 is respectively installed in cooperation with the motor-pulley set 161 and the rotating disc 121, and is used for driving the rotating disc 121 to rotate around its own axis under the driving of the motor-pulley set 161.
The idle pulley 162 presses the elastic ribbed belt 163 from the outside of the elastic ribbed belt 163 to form the elastic ribbed belt 163 at a set wrap angle on the motor-pulley set 161 side.
In this embodiment, since the elastic ribbed belt 163 has better elasticity than the general belt 154, the belt tension value thereof is slightly changed for the same extension length, and thus, a tensioning device is not required to adjust the tension of the elastic ribbed belt 163.
Fig. 4 is a schematic structural diagram of an elastic v-ribbed belt according to an embodiment of the present invention. As shown in fig. 4, the elastic v-ribbed belt 163 according to the embodiment of the present invention includes: an elastic cable backbone 1631 and a hybrid rubber band wedge 1632.
The elastic cable skeleton 1631 may be a polyamide skeleton or the like.
The embodiment of the utility model provides an in CT machine can include foretell drive mechanism.
It can be seen from the above-mentioned scheme that because the utility model discloses in adopt the elasticity polywedge to bring the transmission to come from motor-pulley group's drive power for the carousel to it is rotatory to drive the carousel around the axis of self, and the elasticity polywedge area has better elasticity than ordinary belt, under same extension length, its belt tension value change is very little, consequently need not to need a tensioning device to adjust the tensile force of belt like ordinary belt, consequently, overspeed device tensioner has been left out, the tensioning has been avoided in CT machine's effective life cycle and has been maintained, the maintenance cost is reduced. In addition, the elasticity is carried more and can also effectively absorb vibration and noise, reduces CT machine holistic noise value.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
