Description

Technical Field

[0001] This utility model relates to the field of bearing sealing performance testing technology, and in particular to a rolling bearing sealing performance testing device. Background Technology

[0002] Rolling bearings are critical components widely used in mechanical equipment, and their sealing performance directly affects their service life and the operational stability of the equipment. Good sealing performance can effectively prevent external contaminants (such as dust and moisture) from entering the bearing, while also preventing leakage of internal lubricant, thus ensuring reliable operation of the bearing under complex working conditions. Therefore, testing the sealing performance of rolling bearings is an indispensable part of the production process.

[0003] Currently, existing rolling bearing sealing performance testing technologies have the following shortcomings:

[0004] Traditional testing methods typically require manual placement of bearings one by one at the testing station, which is not only time-consuming and labor-intensive, but also makes it difficult to ensure the accuracy and consistency of placement, resulting in low testing efficiency. The testing process requires multiple manual adjustments and interventions, which increases the complexity of the operation and is prone to human error. Furthermore, the operation usually adopts single-station testing, which cannot achieve multi-station parallel operation, further limiting the improvement of testing efficiency. Utility Model Content

A first cylinder 3 drives the first pusher plate 4 via its piston rod, pushing the bearing on the conveyor 2 into the testing area. A second cylinder 5 drives the second pusher plate 6, further positioning the bearing on the workstation plate 15. A third cylinder 7 drives a fourth cylinder 9 via a connecting plate 8. The piston rod of the fourth cylinder 9 is connected to a dual-workstation material changing plate 10, enabling rapid switching between the two workstations and ensuring the continuity and efficiency of the testing.

[0024] In embodiment 2, a support plate 18 is welded to the top outer wall of the testing platform 1, and a fifth cylinder 11 is symmetrically distributed and fixed to the top outer wall of the support plate 18 by screws.

[0025] In this embodiment, a fifth cylinder 11 is symmetrically distributed on the support plate 18, and the piston rod of the fifth cylinder 11 is connected to the sealing cover 12. The sealing cover 12 is equipped with a pressure sensor 13, which injects gas through the air inlet pipe 14, enabling real-time monitoring of pressure changes to evaluate sealing performance.
