Description

Fan bearing seat with sealing ring

Technical Field

The utility model relates to a fan bearing frame with sealing washer belongs to ventilation equipment technical field.

Background

The blower is a gas conveying device commonly used in the industrial field, and most blowers are also provided with blower bearing boxes. As the technology advances and the design of bearing housings advances, there are still many drawbacks and problems unsolved. The oil leakage of the bearing box is a common problem, because of the high-speed rotation of the main shaft of the fan, after the fan runs for a period of time, lubricating oil splashes along the main shaft to form oil leakage, which is usually unavoidable, the bearing box cannot be sealed, however, the problem of oil leakage often causes the running of the bearing box to be blocked, certain obstruction is brought to production and manufacturing, leaked oil is often blocked around the leaked hole due to the problem of time, dirt mixed with oil and various dusts is difficult to remove, the box body of the bearing box is corroded, and the service life of the box is shortened. Oil leakage gradually becomes a difficult problem restricting the safe operation of equipment and the field civilized production, and frequent oil supplement also increases the cost consumption and the maintenance workload. And if the oil is not supplemented in time, the oil shortage in the box can cause the bearing to be worn and heated, so that the bearing is damaged.

Chinese patent CN204493260U discloses an oil leakage preventing device for a fan bearing box, which comprises a bearing box and a main shaft, wherein the main shaft is fixed in the bearing box through a bearing, an oil slinger is sleeved on the main shaft between the bearing and an outer end cover of the bearing box, a threaded sleeve is sleeved on the main shaft, the threaded sleeve is located between the oil slinger and the outer end cover, and the rotating direction of the threaded sleeve is the inner side of the bearing box. This patent sets up the screw sleeve between oil slinger and outer end cover, thereby can get rid of the lubricating oil that rotates around the oil slinger along the main shaft back to the bearing box inside again and avoid the oil leak. However, the design additionally increases the threaded sleeve, and the structure of the original outer end cover needs to be adjusted to reserve a corresponding space, so that the equipment transformation cost is increased. And because the structure of the outer end cover is changed, a small amount of lubricating oil inevitably overflows from the edge of the outer end cover to flow out of the bearing box.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in the figure, the utility model discloses a fan bearing frame with sealing washer, including bearing frame body 1 and the end cover 2 that is located body 1 both ends, be provided with bearing 3 between two end covers 2, body 1 has the through-hole 4 that can supply the pivot to pass, be provided with sealing washer 5 on the bearing 3, sealing washer 5 is including being located the interior annular support core 51 and being located the elasticity frame 52 of outer loop, elasticity frame 52 and support are provided with spring coil 6 between the core 51.

When the sealing ring 5 is installed, the supporting core body 51 is fixed on the bearing 3, the elastic outer frame 52 can compress the spring ring 6 according to actual needs, good sealing can be formed, meanwhile, the sealing ring can adapt to different bearings 3, and the application range is wider.

Furthermore, the baffle 7 is obliquely arranged on the elastic outer frame 52, the baffle 7 has a folding part 8, the folding part 8 is composed of a first rod 81 and a second rod 82 which are connected, and an included angle between the first rod 81 and the second rod 82 is an acute angle.
