Description

Technical Field

[0001] The present application relates to the technical field of bearing torque testing, and in particular to a bearing torque testing tool. Background Art

[0002] The friction torque of the bearing is an important performance indicator of the bearing. In practical applications, different types of bearings are combined into a shaft system to meet the requirements of working under different load types and speeds. Some bearings are used to bear axial forces, and some bearings are used to bear radial forces. The friction torque of the bearing under the force in a certain direction is obtained by calculation or testing, and then the driving force required by the shaft system is obtained.

[0003] For example, the utility model patent with publication number CN219657168U specifically discloses a large bearing load torque test device, which uses the setting of a joint bearing to offset the micro deflection, thereby avoiding the impact on the detection data of the high-precision force sensor;

[0004] However, the above patent can only measure the torque of the bearing under normal temperature when testing the bearing torque, without measuring other temperature changes. This type of test is different from the actual application conditions. Due to the different working environments and working conditions of the bearing, the friction torque of the bearing itself has a certain impact on its use range and service life. Therefore, it is necessary to design a bearing torque test tool to solve the above problems.

[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0028] like Figure 1-Figure 3 As shown, the present application provides a bearing torque test tool, including a bearing seat 1, on which a main shaft 11 is rotatably arranged, and a seat body 12 for mounting the inner ring of the bearing to be tested is arranged at one end of the main shaft 11 close to the bearing seat 1, and at the same time, a linkage ring 13 for being sleeved on the outer ring of the bearing to be tested and connected thereto is arranged on the bearing seat 1, and force arms 2 are arranged on both sides of the linkage ring 13, and loading members for transmitting radial force to the force arms 2 are arranged on the two groups of force arms 2, and at the same time, detection members for detecting the torque value transmitted to the force arms 2 when the bearing to be tested rotates are arranged on the two groups of force arms 2, and a driving member for driving the main shaft 11 to rotate so as to drive the bearing to be tested to operate is arranged on the bearing seat 1;

[0029] The loading member includes a radial force loading cylinder 21, the output end of which is connected to a static pressure support actuator 22, and the static pressure support actuator 22 is connected to the force arm 2;

[0030] The detection member includes a high-precision force sensor 3 disposed between the static pressure support actuator 22 and the force arm 2;

[0031] The driving member includes a driving motor 4 arranged on the bearing seat 1, the output end of the driving motor 4 is coaxially connected to the main shaft 11, and a connecting plate 14 for connecting to the side of the outer ring of the bearing to be tested is arranged on the bearing seat 1, and an axial loading cylinder 5 is arranged on the connecting plate 14, and the output end of the axial loading cylinder 5 is connected to the outer wall of the connecting plate 14, and the output end of the axial loading cylinder 5 is coaxially arranged with the main shaft 11, and a joint bearing 141 is connected between the force arm 2 and the outer wall of the linkage ring 13;

[0032] In summary, when the bearing detection device is used, the operator installs the bearing to be detected on the seat body 12, and then connects the linkage ring 13 to the outer ring of the bearing to be detected through a connecting piece such as a fixing pin;

[0033] The operator drives the main shaft 11 to rotate so that it drives the bearing to be tested to rotate. When the bearing to be tested rotates, a rotation torque is generated, which is transmitted to the force arms 2 on both sides of the linkage ring 13, and then transmitted to the detection member by the force arms 2. At this time, the detection member detects the torque value and generates a signal to be transmitted to the external intelligent terminal;

[0034] Affected by the rotation direction of the outer ring, when the bearing rotates, the rotation torque values ​​transmitted to the two force arms 2 through the linkage ring 13 are inconsistent, that is, the rotation torque of one of the two force arms 2 is higher than the rotation torque of the other force arm 2. The difference between the rotation torque values ​​detected by the two detection parts is multiplied by the length of the force arm 2 to obtain the torque value of the tested bearing;

[0035] The above is a brief description of the structure and principle of the bearing force arm detection. For details, please refer to the utility model patent with publication number CN219657168U, which will not be repeated in this application.

[0036] In order to perform torque tests on bearings in different working environments and working conditions, such as Figure 2 As shown, a support assembly 9 is fixedly installed on the bottom surface of the bearing seat 1, and the support assembly 9 includes a bottom plate 91 fixedly installed on the bottom surface of the bearing seat 1, and the bottom plate 91 is used to support the bearing seat 1 and the drive motor 4. Four sets of supporting legs 911 are fixedly installed on a side of the bottom plate 91 away from the bearing seat 1;

[0037] like Figure 2 and Figure 4-Figure 5 As shown, a sliding assembly 6 is fixedly mounted on the bottom plate 91, and the sliding assembly 6 includes two sets of slide rails 61 fixedly mounted on the bottom plate 91, and two sets of sliders 62 slide on the slide rails 61, and the sliders 62 slide along the straight direction of the slide rails 61, and a slide plate 63 is connected between the two sets of sliders 62 arranged on the two sets of slide rails 61;

[0038] Two groups of cover plates 7 are fixedly mounted on the slide plate 63 . The two groups of cover plates 7 are butted together to form a sealed space. Meanwhile, a circular groove matching the diameter of the main shaft 11 is formed on the cover plate 7 .

[0039] A heating assembly 8 is fixedly mounted on the inner wall of the cover plate 7, and the heating assembly 8 includes a thermostatic box 81 fixedly mounted on the inner wall of the cover plate 7, a door frame 811 is fixedly mounted on the thermostatic box 81, and the door frame 811 is suitable for mounting a box door to seal the thermostatic box 81, and a temperature and humidity controller 82 is fixedly mounted on the thermostatic box 81, and the temperature and humidity controller 82 is used to control the temperature in the thermostatic box 81, and a power switch 83 is also fixedly mounted on the thermostatic box 81, and the power switch 83 is used to control the opening and closing of the thermostatic box 81;

[0040] In the present application, the door frame 811 is set to an open state so as to be suitable for conveying hot air into the sealed space formed by the two sets of cover plates 7;

[0041] When the bearing seat is subjected to torque test at different temperatures, firstly, the constant temperature box 81 is started, and the temperature and humidity controller 82 is adjusted to set the required test temperature, and then the cover plate 7 is driven to move by pushing the two sets of slide plates 63, so that the two sets of cover plates 7 are docked to wrap the bearing to be tested, so that the temperature in the sealed space where the two sets of cover plates 7 are docked is consistent with the required test temperature set by the temperature and humidity controller 82, thereby completing the setting of the test temperature;

[0042] In the present application, bolts are connected between the two groups of cover plates 7 to prevent the vibration generated when the drive motor 4 is working from causing the two groups of cover plates 7 to deviate to both sides.

[0043] Through the above settings, the bearing torque test can be performed under different ambient temperatures.

[0044] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
