Abstract
Description
Technical Field
[0001] The utility model relates to the field of speed reduction mechanisms, in particular to a speed reduction power mechanism. Background Art
[0002] The CT machine for product inspection is a device that uses computer tomography technology to perform product inspection. It can perform three-dimensional scanning of products in a non-destructive way to obtain high-resolution internal structure information, thereby detecting product defects, foreign matter or other quality problems. During the CT inspection of products, in order to receive X-ray detection signals, a flat-panel detector is required for ray detection imaging.
[0003] During the product inspection process, a rotating mechanism is required to drive the X-ray source to perform rotational scanning of the product. The existing rotating mechanism uses a reduction power mechanism to drive the synchronous bearing to rotate, so that the X-ray source can perform rotational scanning. The existing reduction power mechanism allows the synchronous bearing to rotate through the transmission of a synchronous belt. Therefore, the synchronous belt drives the synchronous bearing to rotate through the friction force of the inner wall. In the process of the synchronous belt driving the synchronous bearing to rotate, it is inevitable that the belt body will become loose, which makes the transmission of the synchronous belt unstable, and further makes the rotational scanning of the X-ray source unstable.

DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] The utility model provides Figure 1-5 A deceleration power mechanism shown includes a fixed plate 1, a synchronous wheel bearing 2 is rotatably interlaced in the middle of the front side of the fixed plate 1, a support frame 101 is arranged at the bottom end of the fixed plate 1, and a support rod 102 is obliquely arranged between the top of the support frame 101 and the top of the fixed plate 1.
[0027] It should be noted that in the setting of this solution, the fixed plate 1 and the support frame 101 are set at a 90-degree angle. At the same time, in order to stabilize this right-angle support structure, a triangular oblique support is formed by an obliquely arranged support rod 102, making the support more stable.
[0028] Specifically, an outer guide frame 3 is provided on the front of the fixed plate 1 and located on the outer wall of the synchronous wheel bearing 2 , and an inner guide frame 4 is provided on the front of the fixed plate 1 and located between the outer wall of the synchronous wheel bearing 2 and the inner wall of the outer guide frame 3 .
[0029] It should be noted that, through the combined design of the outer guide frame 3 and the inner guide frame 4, an arc-shaped guide channel is formed between the two, so that when the detection mechanism is connected at the synchronous wheel bearing 2, the guide channel can be utilized so that the detection mechanism can move synchronously with the synchronous wheel bearing 2.
[0030] In the design of this scheme, the synchronous wheel bearing 2 is a slewing bearing, which is a special type of bearing that allows an object to rotate in the horizontal or vertical direction. It is usually composed of an inner ring, an outer ring, a rolling element and a cage. Slewing bearings have the characteristics of low friction, high stiffness and high load-bearing capacity, and are widely used in industrial machinery, construction machinery, aerospace, automation equipment and other fields. The function of the slewing bearing is to transfer the load and torque to the support and provide smooth rotational motion. It is often used in devices that require rotation, such as lifting equipment, slewing platforms, rotating panels, and vehicle suspension systems. Slewing bearings can withstand large radial forces, axial forces and torques, and have relatively stable motion accuracy and low friction losses.
[0031] A reduction drive structure for driving the synchronous wheel bearing 2 to rotate is arranged on the side of the front face of the fixing plate 1, and a tension wheel structure is arranged between the output end of the reduction drive structure and the connection between the synchronous wheel bearing 2;
[0032] The tensioning wheel structure includes a connecting plate 7 , which is fixedly connected to the side of the front side of the fixing plate 1 , and a rotating roller 701 is arranged on the front side of the connecting plate 7 .
[0033] Specifically, a supporting rotating rod 702 is inserted and connected in the middle of the rotating roller 701 , and one end of the supporting rotating rod 702 is fixedly connected to the front side of the connecting plate 7 .
[0034] It should be noted that the connecting plate 7 is used for connection with the fixed plate 1. By changing the connection position, the position setting of the entire tensioning wheel structure is adjusted, and the supporting rotating rod 702 is used for the rotation support of the roller 701. In this way, through the setting of the roller 701, the roller 701 can be used to extrude and tension the synchronous belt 6, and at the same time, the friction can be reduced during the tensioning process to avoid hindering the rotation of the synchronous belt 6.
[0035] Furthermore, the reduction drive structure includes:
[0036] A driving motor 8, which is arranged at the side of the back side of the fixing plate 1, and a speed reducer is arranged between the output end of the driving motor 8 and the back side of the fixing plate 1;
[0037] The toothed belt wheel 5 is driven, and a synchronous belt 6 is sleeved between the outer wall of the toothed belt wheel 5 and the outer wall of the synchronous wheel bearing 2, and the roller 701 is closely arranged on the outer wall of the synchronous belt 6, and the synchronous wheel bearing 2 is driven to rotate through the synchronous belt 6.
[0038] Furthermore, a fixing frame 801 is sleeved on the outer wall of the driving motor 8, and a first pulley 802 for connecting a speed reducer is sleeved on the output end of the driving motor 8.
[0039] Furthermore, the speed reducer includes:
[0040] A second pulley 10, a connecting rod 501 is inserted and connected in the middle of the second pulley 10, and one end of the connecting rod 501 passes through the fixed plate 1 and is inserted and connected in the middle of the driving toothed pulley 5;
[0041] The driving belt 9 is sleeved on the outer walls of the first pulley 802 and the second pulley 10 .
[0042] It should be noted that the radius of the second pulley 10 is much larger than the radius of the first pulley 802, and the first pulley 802 is connected to the output end of the drive motor 8 that provides driving force. Through such a setting, the output speed of the drive motor 8 is reduced, thereby forming a deceleration rotation conversion.
[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
