[0002] Bearings offer advantages such as strong load-bearing capacity, smooth operation, excellent vibration resistance, and long life. They are found in everything from small household appliances to large steel rolling production lines. Bearing testing machines are essential testing equipment for analyzing bearing load mechanisms and serve as a crucial foundation for analyzing and studying bearing lubrication characteristics and developing innovative designs.

[0003] The lubricity test for bearings requires adding lubricant to the bearings while they are rolling to verify their lubrication properties. However, in existing techniques, adding lubricant while the bearings are rolling is prone to splashing, making it difficult to evenly apply the lubricant to the bearings and quickly adjust the temperature of the lubricant. This results in poor bearing lubrication test results and creates unnecessary trouble for users.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0033] like Figures 1 to 7 As shown, a bearing testing machine in one embodiment of the present invention includes: a test operating table 1, a supporting mechanism 2 and a filling mechanism 3.

[0034] like Figure 1 As shown, the test operation platform 1 is provided with a support base 101 for supporting a test motor 102, ensuring the stability of the test motor 102 and preventing the test motor 102 from shaking or tilting. The test motor 102 is mounted on the support base 101, which is used to drive a drive shaft 106 to rotate and provide power to the test bearing body 202. The test motor 102 is also mounted with a drive shaft 106 to drive the bearing body 202 to rotate, facilitating testing and serving as a transmission.

[0035] like Figures 1 to 3As shown, the test bench 1 is provided with multiple slots 103 for mounting air pumps 104. Each of the slots 103 has an air pump 104 mounted on its sidewalls. This pump supplies gas to the gland frame 301, thereby enabling the gas within the gland frame 301 to push the push slide 303, thereby pushing the lubricant. A delivery hose 105 is fixedly connected to the air pump 104. The other end of the hose 105 is inserted into the gland frame 301 for delivering gas. A limit nut 107 is threadedly connected to the end of the drive shaft 106 that is away from the test motor 102.

[0036] like Figures 1 to 7 As shown, the support mechanism 2 is mounted on the test bench 1 and includes a pair of fixing seats 201 for supporting and securing the bearing body 202. The bearing body 202 is mounted on the fixing seats 201, and a limiting frame 203 is provided on one side of the bearing body 202 to position the bearing body 202 and facilitate the insertion of the filling pipe 302.

[0037] A plurality of evenly distributed fixing bolts 204 are installed on the limiting frame 203 to fix the limiting frame 203 on the fixing seat 201 so that the limiting frame 203 is not likely to fall off.

[0038] Specifically, the bearing body 202 includes an upper tile 2021, a lower tile 2022 and a plurality of rolling shafts 2023. The upper tile 2021 is provided with an oil filling hole 2024 for adding lubricant.

[0039] like Figures 1 to 3 As shown, a pair of electric push rods 205 are installed in the fixing seat 201 to control the lifting and lowering movement of the push rod 206, thereby providing power for driving the lifting and lowering movement of the cover frame 301. The electric push rod 205 is provided with a push rod 206, and the other end of the push rod 206 is fixedly connected to the cover frame 301, which facilitates the lifting and lowering of the cover frame 301.

[0040] like Figures 1 to 6 As shown, multiple filling mechanisms 3 are mounted on the fixing base 201. The filling mechanisms 3 include a gland frame 301 for storing lubricant and facilitating the addition of lubricant to the bearing body 202. A filling pipe 302 is mounted on the gland frame 301. The filling pipe 302 requires a certain amount of pressure to open, so that the filling pipe 302 will only open when a pair of push slides 303 push the lubricant, thereby preventing lubricant leakage when not in use.

[0041] like Figures 1 to 6 As shown, the gland frame 301 is filled with lubricant, and a pair of push slides 303 are slidably provided in the gland frame 301 for squeezing the lubricant. A sealing sleeve 304 is provided on the push slide 303 to achieve a sealing effect, so that the lubricant is not easy to leak.

[0042] Among them, a plurality of limit blocks 305 are installed in the gland frame 301 for limiting the push slide 303 so that the lubricant is not easily in contact with the delivered gas.

[0043] like Figures 1 to 6 As shown, a pair of guide arc rods 306 are fixed within the gland frame 301 to guide the push slide 303, facilitating the extrusion of lubricant by the push slide 303. A heating rod is installed within the guide arc rods 306 to heat the lubricant, thereby facilitating the testing of lubrication properties at different temperatures. One end of the guide arc rods 306 is fixedly connected to a fixed side plate 308, which is used to secure one end of the guide arc rods 306 and prevent them from shaking or tilting.

[0044] like Figures 1 to 6 As shown, the fixed side plate 308 is provided with a plurality of through holes 309 for facilitating the flow of lubricant and preventing the fixed side plate 308 from blocking the lubricant. A push spring 307 is fixedly connected between the push slide 303 and the fixed side plate 308 for pushing the push slide 303 back to its original position, thereby facilitating the re-pushing of the lubricant.

[0045] Specifically, a filling port is opened on the gland frame 301 , and a sealing screw 310 is threadedly connected to the side wall of the filling port, so that the staff can easily add lubricant to the gland frame 301 , and the sealing screw 310 prevents the lubricant from leaking.

[0046] When in use, the bearing body 202 is inserted into the driving shaft 106, and then the bearing body 202 is moved to the bottom of the gland frame 301 and positioned by means of the installation limit frame 203. Then, the electric push rod 205 is used to control the push column 206 to descend, so that the push column 206 can drive the gland frame 301 to descend and press on the bearing body 202, thereby fixing the bearing body 202. Then, the test motor 102 is started to drive the driving shaft 106 to rotate, thereby driving the lower tile 2022 on the bearing body 202 to rotate.

[0047] During the rotation process, gas is delivered to the pressure cover frame 301 through the delivery air pump 104 and the delivery hose 105, so that the gas can push the push slide 303 to move, and then squeeze the lubricant in the pressure cover frame 301, so that the lubricant enters between the upper tile 2021 and the bearing body 202 through the filling pipe 302, thereby facilitating the observation of the lubrication characteristics of the bearing body 202.

[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
