Description

Technical Field

[0001] The present application relates to the technical field of X-ray machine bearings, and in particular to a running-in and life testing device for X-ray machine bearings. Background Art

[0002] X-ray machine bearings are key components in X-ray machines. The performance of X-ray machine bearings directly affects the life of the tube, and thus the use of the entire CT machine. Therefore, life testing and running-in tests of X-ray machine bearings are very important.

[0003] Existing running-in procedures for X-ray machine bearings are mostly fixed-angle, unable to achieve multi-angle running-in and, therefore, unable to simulate the bearing's actual operating environment. For example, an X-ray machine bearing is placed on a horizontal test platform, which cannot rotate with the platform, so the X-ray machine bearing can only be run-in at a horizontal angle. Because existing running-in procedures for X-ray machine bearings cannot accurately simulate the bearing's actual operating environment, they cannot accurately assess the bearing's safety and reliability.

[0004] Existing life tests for X-ray machine bearings can be divided into fixed-angle life tests and multi-angle life tests. If a fixed-angle life test is performed on an X-ray machine bearing, the actual working environment of the bearing cannot be simulated, and thus the service life of the bearing cannot be accurately evaluated. For example, the X-ray machine bearing is placed on a horizontal test platform, and the X-ray machine bearing cannot rotate with the horizontal test platform, so the X-ray machine bearing can only be tested for life at a horizontal angle. If a multi-angle life test is performed on an X-ray machine bearing, the X-ray machine bearing needs to be placed in the entire machine. Although the actual working environment of the bearing can be simulated, the operator is required to be familiar with the cumbersome operating steps, which causes inconvenience to the operator.

[0005] Furthermore, existing life testing methods for X-ray machine bearings work as follows: a matching glass shell assembly is selected based on the size of the X-ray machine bearing, and the bearing sleeve is connected to the glass shell assembly. The glass shell assembly is pre-installed on the glass shell connection port of the vacuum chamber. As can be seen from the above, existing life testing methods for X-ray machine bearings require different glass shell assemblies for different bearing models, which increases material costs. Furthermore, when the bearing is installed in the glass shell assembly, the glass shell assembly and the bearing must be connected through welding, a slow process that affects the efficiency of X-ray machine bearing life testing.

[0006] In addition, the existing running-in test and life test of X-ray machine bearings require the use of two different testing devices, thereby increasing economic costs.

[0007] In view of the technical problem that the above-mentioned existing technology currently lacks a device that can perform multi-angle running-in tests on bearings and multi-angle life tests, thereby being unable to simulate the actual working environment of the bearings and thus unable to ensure accurate evaluation results, no effective solution has been proposed yet. Utility Model Content

[0008] The utility model provides a running-in and life test device for X-ray machine bearings, so as to at least solve the technical problem in the prior art that there is currently a lack of a device that can perform multi-angle running-in tests on bearings and multi-angle life tests, thereby being unable to simulate the actual working environment of the bearings and further unable to ensure that accurate evaluation results can be obtained.

[0009] According to one aspect of the present application, a running-in and life testing device for X-ray machine bearings is provided, comprising: a base, a base bracket and a support assembly, wherein one end of the base bracket is connected to a rotating assembly, and the other end is connected to the base, wherein a first bearing is provided inside the rotating assembly, and the rotating assembly and the base are arranged horizontally; the support assembly is provided at the bottom of the base relative to the rotating assembly and is connected to the base; and the base can rotate around the support assembly.

[0010] Optionally, the support assembly includes: a second bearing and a first support rod, wherein the first support rod is laterally arranged at the bottom of the base relative to the rotating assembly and fixedly connected to the base; and the second bearing is respectively sleeved on both ends of the first support rod.

[0011] Optionally, the support assembly includes: a third bearing and a second support rod, wherein the second support rod is transversely arranged inside the base relative to the rotating assembly; and the third bearing is respectively sleeved on both ends of the second support rod.

[0012] Optionally, a through hole is provided at one end of the base bracket, and the rotating assembly is connected to the base bracket by a bolt passing through the through hole.

[0013] Optionally, the first bearing includes a welding edge, and the base bracket includes an annular groove, wherein the rotating assembly is connected to the base bracket by inserting the welding edge of the first bearing into the annular groove.

[0014] Optionally, the base is provided with a groove, and a slider is provided at the other end of the base bracket, and the base bracket is connected to the groove of the base through the slider and moves along the longitudinal extension direction of the groove.

[0015] Optionally, the rotating assembly includes: a bearing sleeve, wherein the bearing sleeve is sleeved on the outside of the first bearing.

[0016] Optionally, the rotating assembly includes: a screw, wherein the bearing sleeve is fixed to the outside of the first bearing by the screw.

[0017] Optionally, the anode target is fixedly connected to the rotating assembly via a nut.

[0018] This application provides a running-in and life testing device for X-ray machine bearings. The device includes a base, a base bracket, and a support assembly. One end of the base bracket is connected to a rotating assembly, and the other end is connected to the base. A first bearing is disposed within the rotating assembly and is disposed horizontally between the rotating assembly and the base. Furthermore, the support assembly is disposed at the bottom of the base relative to the rotating assembly and is connected to the base. Notably, the base is capable of rotating about the support assembly.

[0019] Because the first bearing, the test object, in this application is located inside the rotating assembly, and the rotating assembly is connected to the base via a base bracket, the rotating assembly can move along with the base. Thus, when the base is able to rotate around the support assembly, the rotating assembly can also rotate around the support assembly along with the base. In other words, both the multi-angle running-in test and the multi-angle life test of the first bearing can be performed using the same device. This significantly reduces economic costs compared to the existing method of requiring two different devices to perform the running-in test and life test on the first bearing, respectively.

[0020] Furthermore, since the apparatus provided herein can be used to perform a multi-angle running-in test on the first bearing, it is possible to simulate the actual operating environment of the first bearing, thereby accurately assessing the safety and reliability of the first bearing. Furthermore, since the apparatus provided herein can be used to perform a multi-angle life test on the first bearing, it is possible to simulate the actual operating environment of the first bearing, thereby accurately assessing the service life of the first bearing. In other words, the apparatus provided herein can be used to obtain accurate assessment results.

[0021] This solves the technical problem in the prior art that there is currently a lack of a device that can perform multi-angle running-in tests on bearings and multi-angle life tests, thereby being unable to simulate the actual working environment of the bearings and thus unable to ensure that accurate evaluation results can be obtained.

[0031] Figure 1Schematic diagram of a running-in and life test device for X-ray machine bearings according to an embodiment of the present application. Figure 2 is a cross-sectional view of a rotating assembly according to an embodiment of the present application. Figure 1 and Figure 2 As shown, a running-in and life testing device for X-ray machine bearings includes: a base 20, a base bracket 30 and a support assembly 40, wherein one end of the base bracket 30 is connected to the rotating assembly 10, and the other end is connected to the base 20, wherein a first bearing 110 is provided inside the rotating assembly 10, and the rotating assembly 10 and the base 20 are horizontally arranged; the support assembly 40 is horizontally arranged at the bottom of the base 20 relative to the rotating assembly 10, and is connected to the base 20; and the base 20 can rotate around the support assembly 40.

[0032] As described in the background section, existing running-in tests for X-ray machine bearings are mostly fixed-angle tests, failing to perform multi-angle running-in tests and, consequently, failing to simulate the actual operating environment of the bearings. For example, an X-ray machine bearing is placed on a horizontal test platform, which cannot rotate with the platform. Therefore, running-in tests can only be performed at horizontal angles. Because existing running-in tests for X-ray machine bearings cannot accurately simulate the actual operating environment of the bearings, they are unable to accurately assess the safety and reliability of the bearings.

[0033] Existing life tests for X-ray machine bearings can be divided into fixed-angle life tests and multi-angle life tests. If a fixed-angle life test is performed on an X-ray machine bearing, the actual working environment of the bearing cannot be simulated, and thus the service life of the bearing cannot be accurately evaluated. For example, the X-ray machine bearing is placed on a horizontal test platform, and the X-ray machine bearing cannot rotate with the horizontal test platform, so the X-ray machine bearing can only be tested for life at a horizontal angle. If a multi-angle life test is performed on an X-ray machine bearing, the X-ray machine bearing needs to be placed in the entire machine. Although the actual working environment of the bearing can be simulated, the operator is required to be familiar with the cumbersome operating steps, which causes inconvenience to the operator.

[0034] Furthermore, existing life testing methods for X-ray machine bearings work as follows: a matching glass shell assembly is selected based on the size of the X-ray machine bearing, and the bearing sleeve is connected to the glass shell assembly. The glass shell assembly is pre-installed on the glass shell connection port of the vacuum chamber. As can be seen from the above, existing life testing methods for X-ray machine bearings require different glass shell assemblies for different bearing models, which increases material costs. Furthermore, when the bearing is installed in the glass shell assembly, the glass shell assembly and the bearing must be connected through welding, a slow process that affects the efficiency of X-ray machine bearing life testing.

[0035] In addition, the existing running-in process for X-ray machine bearings and the life test for X-ray machine bearings require the use of two different testing devices, thereby increasing economic costs.

[0036] In view of this, the present application provides a running-in and life testing device for X-ray machine bearings. The device includes a base 20, a base bracket 30, and a support assembly 40. One end of the base bracket 30 is connected to the rotating assembly 10, and the other end is connected to the base 20. A first bearing 110, serving as a test object, is disposed within the rotating assembly 10. Furthermore, the support assembly 40 is disposed at the bottom of the base 20 relative to the rotating assembly 10 and is connected to the base 20. Notably, the base 20 is capable of rotating about the support assembly 40.

[0037] As can be seen from the above, since the rotating assembly 10 and base 20 are arranged horizontally, and the base 20 can rotate around the support assembly 40, when the base 20 rotates around the support assembly 40, it can also drive the rotating assembly 10 to rotate. Therefore, when the operator needs to perform a running-in test on the first bearing 110, by adjusting the angle at which the base 20 rotates around the support assembly 40, the actual operating environment of the first bearing 110 can be simulated, and a multi-angle running-in test of the first bearing 110 can be performed.

[0038] For example, first, the operator connects the rotating assembly 10, which includes the first bearing 110, to the base support 30 and activates the running-in and life test device. During the period T0 to T1, the base 20 remains horizontal and motionless. That is, during the period T0 to T1, the first bearing 110 within the rotating assembly 10 undergoes a running-in test in a horizontal position. At time T1, the base 20 rotates 30° counterclockwise around the support assembly 40, and during the period T1 to T2, the first bearing 110 within the rotating assembly 10 undergoes a running-in test at a position 30° counterclockwise. At time T2, the base 20 rotates 60° clockwise around the support assembly 40, and during the period T2 to T3, the first bearing 110 within the rotating assembly 10 undergoes a running-in test at a position 30° clockwise.

[0039] As can be seen from the above, by adjusting the rotation angle of the base 20 around the support assembly 40 during different time periods T0-T3, the first bearing 110 within the rotating assembly 10 can be run-in tested at different angles. Unlike conventional methods that only allow the first bearing 110 to be run-in tested at a fixed angle, the running-in and life testing device for X-ray machine bearings in this application can perform multi-angle running-in tests on the first bearing 110 as the test object, simulating the actual operating environment of the first bearing 110. This allows for accurate assessment of the safety and reliability of the first bearing 110.

[0040] Similar to the above, when the operator needs to perform a life test on the first bearing 110, the actual working environment of the first bearing 110 can be simulated by adjusting the angle of rotation of the base 20 around the support assembly 40, and a multi-angle life test of the first bearing 110 can be achieved.

[0041] Compared with the traditional life test of the first bearing 110 at a fixed angle, the running-in and life test device for X-ray machine bearings in this application can perform multi-angle life tests on the first bearing 110 as the test object, simulating the actual operating environment of the first bearing 110, thereby accurately evaluating the service life of the first bearing 110.

[0042] In addition, compared to the traditional method of requiring two different sets of devices to perform running-in test and life test on the first bearing 110 respectively, the present application integrates the multi-angle running-in test and multi-angle life test of the first bearing 110 into a set of devices, so that the multi-angle running-in test and multi-angle life test of the first bearing 110 can be completed by using a set of devices, thereby greatly reducing economic costs and facilitating use by operators.

[0043] Further, refer to Figure 1 and Figure 2 As shown, in the embodiment of the present application, the rotating assembly 10 with the bearing 110 therein is connected to the base 20 via a base support 30. Furthermore, since the present application places the rotating assembly 10 inside the vacuum chamber, rather than at the glass shell interface of the vacuum chamber, there is no need to weld a glass shell assembly to the outside of the rotating assembly 10; it can be directly connected to the base 20 via the base support 30. Therefore, for different models of rotating assemblies 10, only different base supports 30 need to be provided to perform life tests on the bearings within the rotating assembly 10. This can achieve the technical effect of reducing material costs and improving the efficiency of life tests on the bearings 110.

[0044] This solves the technical problem in the prior art that there is currently a lack of a device that can perform multi-angle running-in and multi-angle life testing on bearings, thereby being unable to simulate the actual working environment of the bearings and thus unable to ensure that accurate evaluation results can be obtained.

[0045] Optionally, the support assembly 40 includes: a second bearing 410 and a first support rod 420, wherein the first support rod 420 is horizontally arranged at the bottom of the base 20 relative to the rotating assembly 10 and is fixedly connected to the base 20; and the second bearing 410 is respectively mounted on both ends of the first support rod 420.

[0046] Specifically, refer to Figure 1 As shown, the support assembly 40 includes a second bearing 410 and a first support rod 420. The first support rod 420 is disposed transversely to the bottom of the base 20 relative to the rotating assembly 10, and the first support rod 420 can be fixedly connected to the bottom of the base 20 by welding, for example. Furthermore, the first support rod 420 is also provided with a second bearing 410 at each end, thereby further securing the first support rod 420 to the base 20.

[0047] Therefore, since the first support rod 420 is fixedly connected to the base 20 and the second bearings 410 are sleeved on both ends of the first support rod 420, the base 20 can rotate with the rotation of the first support rod 420, thereby ensuring the technical effect of the multi-angle running-in test of the first bearing as the test object.

[0048] Optionally, the support assembly 40 includes: a third bearing 430 and a second support rod 440, wherein the second support rod 440 is horizontally arranged inside the base 20 relative to the rotating assembly 10; and the third bearing 430 is respectively mounted on both ends of the second support rod 440 and fixedly connected to the second support rod 440.

[0049] Specifically, refer to Figure 1 As shown, the support assembly 40 may further include, for example, a third bearing 430 and a second support rod 440. The second support rod 440 is disposed transversely to the interior of the base 20 relative to the rotating assembly 10. The third bearings 430 are respectively sleeved on both ends of the second support rod 440, thereby further securing the second support rod 440 to the base 20.

[0050] Therefore, since the second support rod 440 is horizontally passed through the interior of the base 20, and the third bearings 430 are sleeved on both ends of the second support rod 440, and the third bearings 430 are fixedly connected to the second support rod 440, the base 20 can rotate around the axis of the second support rod 440, thereby ensuring the technical effect of the multi-angle running-in test of the first bearing as the test object.

[0051] Optionally, a through hole 310 is provided at one end of the base bracket 30 , and the rotating assembly 10 is connected to the base bracket 30 by a bolt 320 passing through the through hole 310 .

[0052] Specifically, refer to Figure 1 As shown, a through hole 310 is provided at one end of the base bracket 30, so that the rotating assembly 10 and the base bracket 30 can be connected by inserting a bolt 320 through the through hole 310 of the base bracket 30 and the rotating assembly 10. This achieves the technical effect of rotating the rotating assembly 10 connected to the base bracket 30 through the rotation of the base 120, thereby ensuring that a multi-angle running-in test can be performed on the first bearing 110 as the test object.

[0053] In addition, it is worth noting that the rotation assembly 10 is detachably connected to the base bracket 30. Therefore, if the operator needs to test different models of rotation assemblies 10, they only need to equip different bolts 320 and base brackets 30.

[0054] Optionally, the first bearing 110 includes a welding edge 140 , and the base bracket 30 includes an annular groove 330 , wherein the rotating assembly 10 is connected to the base bracket 30 by inserting the welding edge 140 into the annular groove 330 .

[0055] Specifically, Figure 3 3 is a partial enlarged view of the base bracket 30 according to the embodiment of the present application. Figure 1 、 Figure 2 and Figure 3 As shown, the first bearing 110 in the rotating assembly 10 is provided with a welding edge 140. Figure 1 and Figure 2 Although not shown, the base bracket 30 includes an annular groove 330. The rotating assembly 10 can be connected to the base bracket 3 by inserting the welded edge 140 of the first bearing 110 into the annular groove 330 of the base bracket 30. This achieves the technical effect of rotating the base 120, driving the rotating assembly 10 connected to it via the base bracket 30, thereby ensuring that multi-angle running-in testing can be performed on the first bearing 110 being tested.

[0056] Optionally, the base 20 is provided with a groove 210 , and a slider is provided at the other end of the base bracket 30 , and the base bracket 30 is connected to the groove 210 of the base 20 through the slider and moves along the longitudinal extension direction of the groove 210 .

[0057] Specifically, refer to Figure 1As shown, the base 20 is provided with two parallel grooves 210, and the other end of the base bracket 30 is provided with sliders corresponding to the two parallel grooves 210. Thus, the base bracket 30 is connected to the grooves 210 of the base 20 via the sliders. The base bracket 30 can also be moved along the longitudinal direction of the grooves 210 via the sliders, thereby facilitating adjustment of the position of the rotating assembly 10.

[0058] Optionally, the rotating assembly 10 includes a bearing sleeve 120, wherein the bearing sleeve 120 is sleeved on the outside of the first bearing 110. Specifically, refer to Figure 2 As shown, the rotating assembly 10 further includes a bearing sleeve 120 disposed outside the first bearing 110 , thereby protecting the first bearing 110 .

[0059] Optionally, the rotating assembly 10 includes a screw 130, wherein the bearing sleeve 120 is fixed to the outside of the first bearing 110 by the screw 130. Specifically, referring to Figure 2 As shown, the rotating assembly 10 further includes screws 130 , and the bearing sleeve 120 is fixed to the outside of the first bearing 110 by the screws, thereby ensuring that the bearing sleeve 120 is firmly sleeved on the outside of the first bearing 110 and will not fall off.

[0060] Optionally, the anode target 50 is fixedly connected to the rotating assembly 10 via a nut 60 .
