The application of chenzhou stainless steel deep groove ball bearing seal

Chenzhou stainless steel deep groove ball bearing seal application/small hong chenzhou stainless steel deep groove ball bearing seal commonly used in what place? Let me/small hong speak slowly! Chenzhou is stainless steel deep groove ball bearing seal bearing in the harsh environment of key parts for normal operation of the bearing seal protection bearing from erosion and pollution, the clean lubrication of the bearing in good condition, prolong the life of bearing. In general, deep groove ball bearing seal are even more important than the dust cover, and is limited by flexible rotation and a relatively low speed rotation. Bearing seal, when the design must consider the performance of the lubricating agent and transportation system and the ideal working conditions. For bearing applications, in use to withstand high load, strong impact and prevent water and rust particles particle invasion, and developed a new type of high load capacity of the sealed type, clean lubrication bearing seals. Experience shows that under the condition of the pollution of the work, bearing inner into clastic particles, and these clastic particles can damage raceway, cause stress concentration. In addition, if the lubrication is not uniform, the metal rigid contact surface, the tiny 'peeling' damage, can also lead to the contact area of stress concentration, the two kinds of results to cause stress concentration areas of the metal surface and crack, and ultimately shorten the bearing life. Research has shown that by changing the organization of the bearing steel, can improve the bearing under the condition of the pollution of impurities or the working life of the edge of the lubrication condition, improve the ability of bearing on the edge of the release of stress concentration. The best bearing practical protective measures are: when impurities appeared, just stop it. New type of deep groove ball bearing seal both the above two advantages. This new type of hole type bearing seal can not only solve the inhibition of form a negative pressure, prevent water from inside the bearing, the primary seal is not directly exposed to the water, from 'breathe' in the water, but also have the impurity blocking function of the groove. Ordinary bearing seal in the rotating and stationary state is linear contact, keep tightly sealed performance of high strength, and this kind of seal, replace the linear contact with surface contact, thereby to adapt to the bearing rotating seal of the requirements of both tight seal, and does not produce large negative pressure. In order to confirm the utility of new hole bearing seals, in the experiment, the bearing working speed range from 100 r/min to 700 r/min, and constantly exert radial load of 294 kn, at the same time, with about 100 l/min water spray. General roller bearing seal during this period, negative pressure increase, and new type hole bearing seal resisting the negative pressure, ensure the normal operation of the work.
