Description

Technical Field

[0001] The utility model relates to the field of full ball bearings, in particular to a high-temperature resistant full ball bearing. Background Art

[0002] A high-temperature resistant full ball bearing is a bearing that can operate stably in a high-temperature environment. In some special application fields, such as aerospace, metallurgy, glass manufacturing, etc., the temperature in the working environment may be very high, exceeding the range that traditional bearings can withstand.

[0003] Since in a high-temperature environment, the grease or lubricating oil of traditional full ball bearings is prone to volatilization or failure, resulting in difficult lubrication, increased friction and wear, poor wear resistance, easy wear phenomenon, reduced reliability and service life of the bearings. Therefore, those skilled in the art have provided a high-temperature resistant full ball bearing to solve the problems raised in the above background art. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a high-temperature resistant full ball bearing is proposed. Through the sealing buckle, oil filling groove and through hole, the oil filling groove provides sufficient storage space for lubricating oil, and the through hole realizes the inlet and outlet of lubricating oil, ensuring that the inside of the bearing always has good lubrication conditions, reducing friction and wear. The setting of the sealing buckle effectively prevents the leakage of lubricating oil, which is only recycled inside the bearing, avoiding waste and environmental pollution. By setting the protective layer and the protection layer, a double protection for the external environment of the bearing is formed. The protective layer effectively prevents substances such as dust and particles from entering the inside of the bearing, and the protection layer isolates the external environment from the internal lubricating part, reducing friction and wear, and can maintain good performance in harsh environments, for applications under harsh working conditions such as high temperature and high speed. The first wear-resistant layer forms the first protection for the friction area of the internal balls of the bearing, and the second wear-resistant layer increases the wear resistance, effectively reducing the wear of the bearing during operation and providing a more stable operation performance, reducing vibration and noise.
