Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically a novel bearing with a windproof cover. Background Technology

[0002] Bearings are critical components in machinery, used to determine the relative position of rotating shafts and other parts. Their quality directly affects the overall performance of the machine. To prevent dust and other contaminants from entering the bearing and to seal the lubricating oil, thereby improving bearing performance and service life, a sealing mechanism is usually installed between the inner and outer rings of the bearing. Existing mounted fan bearings with external spherical roller bearings suffer from problems due to high wind speeds, which allow oil and dust to enter the bearing housing. Although traditional bearings have some protective measures, with many using rubber lips as a sealing mechanism, this sealing method has significant defects in high-wind-speed environments, resulting in unsatisfactory performance and premature bearing failure. Utility Model Content

[0003] The purpose of this invention is to provide a novel bearing with a windproof cover to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A novel bearing with a windproof cover, comprising a vertical bearing housing, a windproof cover, and an end cover. The outer rings of both the windproof cover and the end cover are provided with multiple bolts. The windproof cover is fixedly installed at one end of the vertical bearing housing by multiple bolts, and the end cover is fixedly installed at the other end of the vertical bearing housing by multiple bolts. An outer bearing ring and two windproof covers located at both ends of the outer bearing ring are fixedly arranged inside the vertical bearing housing. An inner bearing ring is provided inside the outer bearing ring, and a spindle is installed inside the inner bearing ring. Two sealing rings and multiple steel balls are provided between the outer and inner bearing rings. The opposite sides of the two windproof covers are connected to the opposite sides of the two sealing rings, thereby improving the windproof and dustproof functions of the fan bearing.

[0005] Preferably, both windshields are annular and concentric with the center hole of the bearing inner ring.

[0006] Preferably, two retainers are provided between the outer ring and the inner ring of the bearing. The two retainers are located on both sides of the multiple steel balls. The two retainers clamp the multiple steel balls from both ends, limit and fix the multiple steel balls, and improve the stability of the multiple steel balls.

[0007] Preferably, the two sealing rings are located at the opening of the gap between the outer ring and the inner ring of the bearing, and the two sealing rings seal the gap between the outer ring and the inner ring of the bearing from both ends.

[0008] Preferably, both wind deflectors are fitted onto the inner ring of the bearing, and the two wind deflectors are in contact with the opposite sides of the two sealing rings. The wind deflectors serve to block the wind and prevent dust and oil from being blown in due to poor bearing sealing.

[0009] Preferably, the mandrel extends through the middle of the windproof cover to the outside, and a windproof sealing ring is fixedly provided at the connection between the windproof cover and the mandrel to seal the connection between the windproof cover and the mandrel.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the additional windproof device can completely prevent oil and dust blown in by strong wind from entering the bearing chamber, avoid the bearing failure caused by dust and oil blowing in due to poor bearing sealing, thereby improving the service life of the bearing.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please see Figure 1-3This utility model provides a novel bearing with a windproof cover, including a vertical bearing housing 1, a windproof cover 8, and an end cover 10. Both the outer ring of the windproof cover 8 and the outer ring of the end cover 10 are provided with multiple bolts 11. The windproof cover 8 is fixedly installed at one end of the vertical bearing housing 1 by the multiple bolts 11, and the end cover 10 is fixedly installed at the other end of the vertical bearing housing 1 by the multiple bolts 11. A bearing outer ring 2 and two windproof covers 7 located at both ends of the bearing outer ring 2 are fixedly installed inside the vertical bearing housing 1. A shaft is provided on the inner side of the bearing outer ring 2. The bearing inner ring 3 is equipped with a spindle 12. Two sealing rings 6 and multiple steel balls 4 are provided between the bearing outer ring 2 and the bearing inner ring 3. The opposite sides of the two wind shields 7 are connected to the opposite sides of the two sealing rings 6. The windproof cover 8 and the end cover 10 are respectively installed at both ends of the vertical bearing seat 1, so that the bearing in the vertical bearing seat 1 is in the closed space wrapped by the windproof cover 8 and the end cover 10, which plays a sealing role and prevents dust and oil from being blown in due to poor bearing sealing.

[0017] Both wind shields 7 are annular and concentric with the center hole of the bearing inner ring 3. The two sealing rings 6 are located at the opening of the gap between the bearing outer ring 2 and the bearing inner ring 3. Both wind shields 7 are fitted onto the bearing inner ring 3, and the two wind shields 7 are in contact with the opposite sides of the two sealing rings 6. The wind shields 7 and sealing rings 6 improve the bearing's sealing performance and prevent dust and oil from being blown in, which could cause premature bearing failure.

[0018] Two retainers 5 are provided between the outer ring 2 and the inner ring 3 of the bearing. The two retainers 5 are located on both sides of the multiple steel balls 4. The retainers 5 are used to limit and fix the multiple steel balls 4, prevent the multiple steel balls 4 from falling off, and improve the working stability of the multiple steel balls 4.

[0019] The spindle 12 extends through the middle of the windproof cover 8 to the outside. A windproof sealing ring 9 is fixedly installed at the connection between the windproof cover 8 and the spindle 12 to play a sealing role and improve the sealing performance.
