AIR-FOIL BEARING DEVICE FOR HIGH SPEED AND HEAVY-DUTY POSSIBLE MAINTAINING ACCURACY

摘要

The present invention relates to a high speed and high duty air foil bearing device capable of maintaining accuracy and, more specifically, relates to a high speed and high duty air foil bearing device capable of maintaining accuracy, and to maintain accuracy without performing bending and welding processes for a top foil even if the thickness of the top foil is increased by 0.5-5 mm. According to this, mass production is realized, and a rate of defect due to the vibration generated during rotation is removed by installing the device in a high speed and high duty shaft such that a reliability of the product is enhanced. The device comprises: a bearing housing; a bump foil; a top foil; a ring shaped bearing cap; and a bump sheet.
