Technical Field

[0001] This utility model relates to the field of sealed bearing manufacturing technology, and in particular to a waterproof performance testing machine for sealed bearings. Background Technology

[0002] The most important performance characteristic of sealed bearings is their waterproof performance. Therefore, after completing the testing, sealed bearings usually need to undergo waterproof performance testing. Traditional waterproof tests are immersion tests. However, sealed bearings are not immersed in water during actual use; instead, they are sprayed or splashed with water. Therefore, immersion tests are obviously inconsistent with actual use conditions, and the data from such tests cannot be used to measure the waterproof performance of sealed bearings. Utility Model Content

[0003] To address the issue that existing sealed bearings do not actually experience water immersion during use, and that water immersion tests are clearly inconsistent with real-world conditions, thus the data from such tests cannot be used to measure the waterproof performance of sealed bearings, this application provides a waterproof performance testing machine for sealed bearings, with the specific solution as follows.

[0005] By adopting the above technical solution, the bearing can be detachably connected to the positioning component on the workbench, making it easy to replace different bearings for testing; the drive motor can drive the bearing to rotate, simulating the actual working state of the bearing; the spray head is set towards the positioning component, which can spray water onto the bearing, thereby realizing the test of the waterproof performance of the sealed bearing. Compared with the immersion test, this water spray test method is more in line with the actual use situation, so the test of waterproof performance is more accurate.

[0006] Optionally, the positioning component includes a positioning sleeve for wrapping the bearing. The positioning sleeve has a fixing hole corresponding to the bearing, and a fixing bolt is threaded into the fixing hole. The fixing bolt can abut against the outer ring of the bearing.

[0012] Optionally, the bottom of the positioning rod is provided with a limiting protrusion, and the positioning sleeve is provided with a limiting hole corresponding to the limiting protrusion, and the limiting protrusion can extend into the limiting hole.

[0013] By adopting the above technical solution, the limiting protrusion at the bottom of the positioning rod extends into the limiting hole of the positioning sleeve, which can further limit and fix the positioning sleeve and the bearing, ensuring the stability of the bearing during the testing process.

[0014] Optionally, the workbench is further provided with a drive seat, on which a transmission component is rotatably connected. The transmission component is connected to the shaft of the drive motor. A mating key is detachably connected to the transmission component, and the mating key is used for the transmission connection between the bearing and the drive seat.

[0015] By adopting the above technical solution, a drive seat is set on the workbench. The drive seat is rotatably connected to the transmission component and is connected to the drive motor shaft. The mating key is detachably connected to the transmission component for transmitting power between the bearing and the drive seat. This realizes the effective transmission of power from the drive motor to the bearing, which can drive the bearing to rotate. The mating key is also detachable, which is convenient for replacement and maintenance.

[0016] Optionally, a transmission belt is provided between the transmission component and the drive motor.

[0017] By adopting the above technical solutions, the transmission belt makes the transmission process smoother, can buffer and absorb vibration, and reduces the impact and vibration between the drive motor and the transmission components.

[0018] Optionally, the workbench is provided with multiple positioning components and drive motors, and a baffle is provided on the workbench for each positioning component, with the baffle surrounding the corresponding positioning component.

[0019] By adopting the above technical solutions, multiple positioning components and drive motors are set on the workbench to simultaneously test the waterproof performance of multiple bearings, thereby improving testing efficiency. The shielding plate surrounding the corresponding positioning components can prevent spray water from splashing out and affecting other test areas, ensuring the stability of the test environment and the accuracy of the test results.

The spray head is set on the adjustment block, and the height position of the spray head can be flexibly adjusted to adapt to the testing requirements of bearings of different specifications, better simulate different waterproof testing environments, and improve the applicability and testing accuracy of the testing machine.

[0022] Optionally, the spray head is rotatably connected to the adjusting block and the angle can be locked.

[0023] By adopting the above technical solution, the spray head is set on the adjusting block and rotatably connected to the adjusting block and can be locked at the angle.

[0024] In summary, this application has at least the following beneficial effects: This application addresses the problem that existing sealed bearings do not actually experience water immersion during use, and water immersion tests are clearly inconsistent with actual usage conditions. The data from such tests cannot be used to measure the waterproof performance of sealed bearings. This application tests bearings by spraying water onto rotating bearings, which is more accurate than water immersion tests and can effectively determine the waterproof performance of bearings.

The workbench 1 is characterized by having a positioning component 2 for detachably connecting a bearing, a drive motor 11 for driving the bearing, and a spray head 3 corresponding to the drive motor 11, with the spray head 3 facing the positioning component 2. In practice, a flow meter is installed on the side wall of the workbench 1 to control the flow rate of the spray head 3. The spray head 3 continuously sprays water onto the rotating workpiece, spraying each workpiece for the same amount of time. If leakage occurs, it indicates insufficient waterproofing performance; if no leakage occurs, it indicates satisfactory waterproofing performance.

[0030] like Figure 1 and Figure 2 As shown, the positioning component 2 includes a positioning sleeve 21, which is used to enclose the bearing. The positioning sleeve 21 has a fixing hole 211 corresponding to the bearing, and a fixing bolt 212 is threaded into the fixing hole 211. The fixing bolt 212 can abut against the outer ring of the bearing. In specific implementation, the bearing needs to be installed in the positioning sleeve 21 during installation. At this time, the outer ring of the bearing is fixed, while the inner ring can still rotate, thereby simulating the working state of the bearing.

[0031] like Figure 1 and Figure 2As shown, the positioning assembly 2 also includes a positioning frame 22, on which a movable component 221 is slidably connected. The movable component 221 can move along the vertical direction of the positioning frame 22. A positioning rod 222 is provided at the lower end of the movable component 221, which abuts against the positioning sleeve 21.

The transmission component 121 is connected to the rotating shaft of the drive motor 11. A mating key 122 is detachably connected to the transmission component 121. The mating key 122 is used for the transmission connection between the bearing and the drive base 12. A transmission belt 123 is provided between the transmission component 121 and the drive motor 11. In a specific implementation, the transmission component 121 is columnar and can rotate under the drive of the transmission belt 123, thereby driving the bearing.

[0033] like Figure 1 and Figure 2 As shown, the workbench 1 is equipped with multiple positioning components 2 and drive motors 11. Each positioning component 2 on the workbench 1 is surrounded by a baffle plate 23. In this embodiment, two positioning components 2 and two drive motors 11 are provided, along with two sets of corresponding baffle plates 23, enabling dual-station testing. In other embodiments, the test water can be collected and reused, thereby improving water resource utilization.

[0034] like Figure 1 and Figure 2 As shown, a spray frame 31 is provided on the workbench 1 corresponding to the spray head 3. An adjusting block 32 is slidably mounted on the spray frame 31. The adjusting block 32 can slide along the vertical direction of the spray frame 31 and can be locked in position. The spray head 3 is mounted on the adjusting block 32. The spray head 3 and the adjusting block 32 are rotatably connected and can be locked at an angle. In specific implementation, the spray head 3 can be adjusted by rotation through a threaded connection, while the vertical adjustment can be achieved by opening a slot and positioning it with bolts.

[0035] Working principle: The bearing is tested by spraying water onto it while it is rotating. This method is more accurate than immersion testing and can effectively determine the bearing's waterproof performance.
