[0001] The utility model relates to a balancing mechanism applied to a bearing detection platform. Background Technique

[0002] The sliding bearing is a non-standard part, and there are specific requirements for the performance of the sliding bearing in some specific occasions. If the sliding bearing is directly used without being tested, and if some of its parameters do not meet the standards and are applied to the transmission structure, it will have a great impact on the transmission accuracy and structural reliability of the transmission structure. Therefore, it is necessary to test the applied bearing to detect its maximum load, rotation speed, and temperature change, so as to ensure that the bearing can be suitable for the required working conditions.

[0003] In the prior art, the radial load detection of the bearing is carried out by pushing and applying pressure through an oil cylinder. However, during the test, relative movement or the tendency of relative movement may occur between the frame for installing the bearing to be tested and the mounting frame for installing the oil cylinder due to the thrust, and the bearing to be tested may tilt, resulting in the situation that the loading position of the axial force is not on the axis of the bearing to be tested. This will affect the detection accuracy of the load of the bearing to be tested, thus affecting the test data and the test results. Content of the Utility Model

Detailed Embodiments

[0017] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.

[0018] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0019] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "over", and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath", and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0020] As Figure 1 shown, a balancing mechanism 10 applied to a bearing detection platform of the present application includes a jacking oil cylinder 12 and a bearing to be tested. The bearing to be tested is installed on a frame 11, and the jacking oil cylinder 12 is installed on a mounting bracket 13. During installation, the jacking oil cylinder 12 is installed on one side of the bearing to be tested through the mounting bracket 13. In this way, by applying an axial thrust to the connecting end of the bearing to be tested through the output end of the jacking oil cylinder 12, the radial load force of the bearing to be tested can be detected.

[0021] Further, two balance components 14 are installed between the frame 11 and the mounting bracket 13. The two balance components 14 are symmetrically distributed on both sides of the bearing to be measured. In this way, a horizontal tensile force can be provided to keep the relative position between the frame 11 and the mounting bracket 13 constant. Thus, when the axial thrust is applied by the jacking oil cylinder 12, the balance component 14 can prevent relative displacement between the frame 11 and the mounting bracket 13, so as to ensure that the bearing to be measured has a stable installation environment for the detection of radial load force. Specifically, the balance component 14 includes: two connecting rods 141. One end of each of the two connecting rods 141 is rotatably connected to the frame 11 and the mounting bracket 13 respectively. In this way, the two rods can rotate relative to each other when pulled, and can cope with external forces applied in multiple directions. The other ends of the two connecting rods 141 are both rotatably connected with rotating members 142. In this way, no matter in which direction the external force is applied, the rotating member 142 can rotate and adjust itself to offset the influence of the external force and ensure the relative position between the frame 11 and the mounting bracket 13. A pull rod 143 is rotatably installed between the two rotating members 142. The rotational installation of the pull rod 143 can further improve the performance of offsetting external forces.

[0022] In the above solution, both ends of the pull rod 143 are rotatably connected to the corresponding rotating members 142 through rotating shafts 144. The rotation direction of the pull rod 143 is perpendicular to the rotation direction of the rotating member 142. The rotation axis of the rotating member 142 coincides with the rotation axis of the connecting rod 141. Such an installation structure is simple. One end of the rotating member 142 is directly sleeved on the outer periphery of the connecting rod 141, so that the rotating member 142 and the connecting rod 141 can rotate axially by 360 degrees. Then, the pull rod 143 performs radial rotation adjustment through the rotating shaft 144, making the overall performance of the balance component 14 in offsetting external forces more excellent.

[0023] Based on the above structure, the balance mechanism 10 of the present solution applied to the bearing detection platform adopts the balance component 14 to ensure a stable relative position between the frame 11 for installing the bearing to be measured and the mounting bracket 13 of the mounting oil cylinder, avoiding relative movement between the frame 11 and the mounting bracket 13, thus ensuring the detection accuracy of the load of the bearing to be measured, and further ensuring the use reliability and safety of the bearing to be measured.

[0024] As a specific implementation, the pull rod 143 includes: a hydraulic cylinder 1431 and two hydraulic rods 1432. The two hydraulic rods 1432 are respectively telescopically installed on both sides of the hydraulic cylinder 1431, that is, a hydraulic cylinder 1431 cylinder structure with two telescopic cylinder rods. The mutually remote ends of the two hydraulic rods 1432 are rotatably connected to the corresponding rotating parts 142 through a rotating shaft 144. By means of the hydraulic cylinder 1431, an axial thrust or pull can be applied to the frame 11 and the mounting bracket 13, so as to be able to simulate applying an external force to the mounting structure of the bearing to be tested. By comparing with the detection situation when the mounting structure is not subject to an external force, the influence of the radial load force of the mounting structure of the bearing to be tested when it is subject to a force can be detected.

[0025] Furthermore, a pressure sensor is provided between the connection end of the rotating part 142 and the connecting rod 141. The pressure sensor is communicatively connected to the hydraulic cylinder 1431. By means of the pressure sensor, the pressure values between the two ends of the balance assembly 14 and the frame 11 and the mounting bracket 13 respectively can be detected. When the detected value of the pressure sensor exceeds the preset range, the tensile or thrust adjustment can be carried out through the telescopic structure of the hydraulic cylinder 1431, so as to ensure the relative position stability between the frame 11 and the mounting bracket 13.

[0026] As a specific implementation, the balance assembly 14 is further provided with a buzzer 145. The pressure sensor is communicatively connected to the buzzer 145. When the detected value of the pressure sensor is greater than the preset value and less than the second preset value, that is, when the detected value of the pressure sensor exceeds the preset range, an alarm is given.

[0027] As a specific implementation, the hydraulic rod 1432 includes: a telescopic rod 1433 and a rotating rod 1434. One end of the telescopic rod 1433 is telescopically connected to the hydraulic cylinder 1431. The two ends of the rotating rod 1434 are respectively rotatably connected to the other end of the telescopic rod 1433 and the rotating part 142. In this way, the telescopic rod 1433 and the hydraulic cylinder 1431 can rotate relative to the two side rotating rods 1434 as a whole. When the connecting rod 141, the rotating part 142 and the rotating rod 1434 rotate to adjust and offset the external force, it does not affect the telescopic structure of the hydraulic cylinder 1431, and the reliability of the overall structure is high. A U-shaped part 1435 is rotatably connected to the end of the rotating rod 1434 far from the telescopic rod 1433. One end of the U-shaped part 1435 is rotatably sleeved on the end of the rotating rod 1434 far from the telescopic rod 1433, and the other end is rotatably connected to the rotating part through a rotating shaft 144. In this way, the articulated connection structure of the U-shaped part 1435 can improve the structural stability of the overall balance assembly 14.

[0028] The basic principles, main features, and advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the above embodiments do not limit the present utility model in any form. Any technical solutions obtained by using equivalent replacements or equivalent transformations fall within the protection scope of the present utility model.
