Coating sealing test testing machine

Abstract

The invention relates to a coating sealing test testing machine which comprises a base, an image acquisition system, a sealing cavity-rotating shaft system and a driving system, the sealing cavity-rotating shaft system and the driving system are installed on the base, the sealing cavity-rotating shaft system is connected with the driving system, the sealing cavity-rotating shaft system is driven by the driving system to operate, and meanwhile rotating speed adjustment is achieved. The image acquisition system is located on one side of the base, and a microscope system in the image acquisitionsystem extends into a rotating shaft of the sealed cavity-rotating shaft system to perform image acquisition. According to the invention, based on original data acquired in multiple groups of repetitive control test processes, the leakage prevention performance of the coating material is evaluated by the acquired images and the leakage amount of the lubricant. The rotating speed range which can berealized by a testing device is 0-3000rpm; the testing torque range is 0-0.6 NM, and a new test means can be provided for the related fields of controlling and sealing by adopting a novel material.

Description

technical field [0001] The invention relates to a coating sealing test machine, which belongs to the technical field of lubrication and sealing testing. Background technique [0002] The quality of the sealing performance plays a very important role in the life of the bearing. Good sealing can prevent dust, water and other debris from entering the bearing, and at the same time prevent the loss of lubricant inside the bearing. At present, most rolling bearings are sealed with sealing rings, and the material is rubber products. In contact with the rotating shaft, wear and tear is inevitable. With the extension of running time, the sealing effect will inevitably weaken, which will have a huge impact on the operation of rolling bearings. In addition, in some precision machinery, such as in robot bearings, the use of traditional sealing rings will affect the accuracy of the operation of the entire mechanical product. Therefore, how to improve the sealing performance of bearings...

However, most of the mechanically durable amphobic coatings reported so far are still in the laboratory stage, and the aging resistance and chemical stability of the amphobic coatings need to be further improved. It is still in the preliminary development stage, so the researchers aim to prepare amphiphobic coatings with better mechanical properties and carry out sealing tests closer to actual working conditions
