Description

Technical Field

[0001] This invention relates to the field of bearing housing structure technology, specifically a transparent continuous annealing furnace roller bearing housing that is easy to inspect. Background Technology

[0002] Most bearing housings are lubricated using either thin oil or grease. Thin oil lubrication offers advantages such as low frictional power consumption and good cooling, but it is difficult to seal and prevent leakage. Grease lubrication, on the other hand, has a simple structure and good sealing, but poor heat dissipation. Annealing furnace roller bearing housings in CAL continuous annealing lines, CGL hot-dip galvanizing lines, and GAL continuous plating lines generally use thin oil lubrication. To promptly detect oil quality and oil shortage issues, manual inspection is currently the standard practice. Oil sight glasses with through holes are installed at both ends of the bearing housing to observe the internal condition.

[0003] Due to the high temperature of the annealing furnace, the lubricating oil is constantly exposed to a high-temperature environment, which easily leads to oxidation and failure, resulting in blackening and thickening. It also produces corrosive substances, carbon deposits, and sludge, causing the oil sight glass to darken and become clogged. This makes it impossible for manual inspection to accurately determine the true lubrication condition of each bearing housing, posing a significant threat to the normal operation of the equipment. Currently, there are other automated detection methods, such as using temperature and vibration detection to determine the operating status of the furnace roller bearing housings. However, such equipment is complex in structure, expensive, and provides delayed results, making it largely unsuitable for similar annealing furnace production lines both domestically and internationally.

[0004] Furthermore, poor lubrication and damaged oil seals can also cause oil abnormalities or oil shortages, leading to bearing damage. Moreover, the bearing rotation cannot be directly observed manually. If bearing malfunctions are not detected in a timely manner, ultimately resulting in furnace roller bearing failure and production line shutdown, will cause significant losses. Therefore, improvements to the bearing housing structure are necessary. Summary of the Invention

[0005] To address the problems mentioned in the background technology, this solution provides a transparent continuous annealing furnace roller bearing housing that facilitates inspection. It allows for a clear view of the inside of the bearing housing on the operating side, enabling a more intuitive and clear inspection of the internal condition of the bearing housing. This effectively ensures the accuracy of the inspection and avoids malfunctions caused by the inability to detect problems in a timely manner.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: a transparent continuous annealing furnace roller bearing seat that is easy to inspect, including a base, an inner pressure cover, an outer pressure cover, and a transparent lens. The right end face of the base is provided with a mounting part. The inner pressure cover and the outer pressure cover are stacked and installed in sequence at the mounting part. The middle of the mounting part is recessed to form a bearing seat hole. Both the inner pressure cover and the outer pressure cover are flange rings. The inner pressure cover and the outer pressure cover are provided with through holes corresponding to the bearing seat hole. The transparent lens is installed between the inner pressure cover and the outer pressure cover and blocks the through holes. In this way, the inside of the bearing seat hole can be directly seen through the transparent lens.

[0007] Furthermore, the inner and outer pressure covers are provided with lens mounting grooves for fastening the transparent lens, making the structure more stable.

[0008] Furthermore, a first sealing ring is provided between the transparent lens and the inner pressure cover, and a second sealing ring is provided between the transparent lens and the outer pressure cover.

[0009] Furthermore, the inner and outer pressure covers are respectively provided with sealing ring mounting grooves for installing the first and second sealing rings.

[0011] Furthermore, a sealing gasket is provided between the vertical end face and the mounting part.

[0012] Furthermore, the inner pressure cover is connected to the mounting part by a first screw, and the inner pressure cover and the outer pressure cover are respectively provided with a plurality of first countersunk holes and first through holes that cooperate with the first screw; the outer pressure cover is connected to the mounting part by a second screw, and the inner pressure cover and the outer pressure cover are respectively provided with a plurality of second through holes and second countersunk holes that cooperate with the second screw; the outer pressure cover is connected to the inner pressure cover by a third screw, and the outer pressure cover is provided with a plurality of third countersunk holes that cooperate with the third screw; the first through holes, second countersunk holes and third countersunk holes are evenly distributed in a circular pattern on the outer pressure cover, and the first through holes, second countersunk holes and third countersunk holes are staggered at intervals. The base, inner pressure cover and outer pressure cover are connected in pairs, making the connection between the three more stable.

[0013] Furthermore, the specifications of the first, second, and third sealing rings are preferably G-series specifications, and the material is preferably nitrile rubber, which has the characteristics of heat resistance and strong oil resistance, and is suitable for the high-temperature environment of the furnace area.

[0014] Furthermore, the transparent lens is made of tempered glass, which has good thermal stability, is not easy to cause injury after breaking, can withstand temperature differences of more than 250°C, and is suitable for high temperature differences in the furnace area. Its thickness is preferably 2mm~8mm.

[0015] The beneficial effects of this invention are: simple structure, easy installation, and easy inspection of lubricating oil level and quality through the transparent lens, easy inspection of bearing operation, easy inspection of lock nut washer condition, and easy inspection of oil seal condition; the inside of the bearing housing on the operating side can be clearly seen, allowing for more intuitive and clear inspection of the internal condition of the bearing housing, effectively ensuring the accuracy of the inspection and avoiding faults caused by failure to detect faults in a timely manner.
