Abstract

The invention provides a screw conveyor hanging bearing with a sealing structure, which comprises a bearing seat, wherein a shaft is arranged on the bearing seat, the shaft is arranged in the bearing seat through flange plates at two ends, spherical outer roller bearings are arranged at the upper side and the lower side of the shaft, oil pressing and injecting cups are arranged at two sides of the shaft, the bearing is sealed in a double oil seal mode through the oil pressing and injecting cups, dust is prevented from entering the middle of the bearing seat, a rotary shaft lip-shaped sealing ring is arranged on the outer side of the spherical outer roller bearing, and the sealing performance of the spherical outer roller bearing is improved through the rotary shaft lip-shaped sealing ring. The suspension bearing is internally provided with the spherical roller bearing, two ends of the bearing are respectively provided with the two pressure filling oil cups, and a certain amount of lubricating grease is added between the two pressure filling oil cups, so that dust in the external environment can be effectively protected from entering the interior, the intermediate bearing is effectively protected from long-term operation and damage, and the service life of the intermediate bearing is prolonged by more than four times by using the suspension bearing on site by a user.

Description

Hanging bearing of screw conveyer with sealing structure

Technical Field

The invention relates to the fields of solid bulk cargo conveying, environmental protection, building materials, chemical engineering and the like, in particular to a suspension bearing of a screw conveyor with a sealing structure.

Background

The screw conveyer is a universal solid bulk material conveying device, and drives a screw shaft to rotate through a driving device arranged at the head of the screw conveyer, so that the aim of conveying materials is fulfilled. The screw shafts are connected by a suspension bearing, so that long-distance conveying is achieved. Because the suspension bearing is always in dust, the suspension bearing used in the earlier stage uses a sliding bearing with a copper tile structure and a babbit alloy structure and the like, so that the abrasion is very fast, the service life is very short, the abrasion is high, and the service life is less than or equal to half a year. The later stage changes into high chromium cast iron structure hanger bearing, though has improved the wearability, but high chromium cast iron structure slide bearing, the wearing and tearing between axle and the axle bush bring very big noise, pollute the service environment, bring very big puzzlement for the user.

Disclosure of Invention

The invention aims to provide a spiral conveyor hanging bearing with a sealing structure, wherein an outer spherical roller bearing is arranged in the hanging bearing, two skeleton oil seals are respectively arranged at two ends of the bearing, and a certain amount of lubricating grease is added between the two skeleton oil seals, so that dust in the external environment can be effectively prevented from entering the interior, the middle bearing can be effectively protected from long-term operation, and the middle bearing can not be damaged.

The invention provides a screw conveyor hanging bearing with a sealing structure, which comprises a bearing seat, wherein a shaft is arranged on the bearing seat, the shaft is arranged in the bearing seat through flange plates at two ends, spherical outer roller bearings are arranged at the upper side and the lower side of the shaft, oil pressing and injecting cups are arranged at two sides of the shaft, the bearing is sealed in a double oil seal mode through the oil pressing and injecting cups, dust is prevented from entering the middle of the bearing seat, a rotary shaft lip-shaped sealing ring is arranged on the outer side of the spherical outer roller bearing, and the sealing performance of the spherical outer roller bearing is improved through the rotary shaft lip-shaped sealing ring.

The further improvement lies in that: the flange plate is fixed through the hexagon socket head guide stud screws, and the number of the hexagon socket head guide stud screws is four.

The further improvement lies in that: and a hanging rod is arranged at the upper end of the bearing seat and is fixed with the bearing seat through a connecting bolt.

The further improvement lies in that: and a V-shaped rubber sealing ring is arranged between the shaft and the outer spherical surface roller bearing, and the sealing property of the outer spherical surface roller bearing is improved through the V-shaped rubber sealing ring.

The invention has the beneficial effects that: the suspension bearing is internally provided with the spherical roller bearing, two ends of the bearing are respectively provided with the two pressure filling oil cups, and a certain amount of lubricating grease is added between the two pressure filling oil cups, so that dust in the external environment can be effectively protected from entering the interior, the intermediate bearing is effectively protected from long-term operation and damage, and the service life of the intermediate bearing is prolonged by more than four times by using the suspension bearing on site by a user.

Detailed Description

For the purpose of enhancing understanding of the present invention, the present invention will be further described in detail with reference to the following examples, which are provided for illustration only and are not to be construed as limiting the scope of the present invention.

As shown in fig. 1, this embodiment provides a seal structure screw conveyer hanging bearing, including bearing frame 1, install axle 2 on the bearing frame 1, axle 2 is installed in bearing frame 1 through the ring flange 3 at both ends, the upper and lower both sides of axle 2 are provided with exterior sphere roller bearing 4, 2 both sides of axle are provided with pressure filling oil cup 5, carry out two oil blanket sealings through pressure filling oil cup 5 to the bearing, prevent in the middle of the dust gets into bearing frame 1, the exterior sphere roller bearing 4 outside is provided with rotation axis lip seal 6, promotes through rotation axis lip seal 6 exterior sphere roller bearing 4's leakproofness. The flange 3 is fixed by hexagon socket head cap screws 7, and the number of the hexagon socket head cap screws 7 is four. The upper end of the bearing seat 1 is provided with a hanging rod 8, and the hanging rod 8 is fixed with the bearing seat 1 through a connecting bolt 9. A V-shaped rubber sealing ring 10 is arranged between the shaft 2 and the outer spherical surface roller bearing 4, and the sealing performance of the outer spherical surface roller bearing 4 is improved through the V-shaped rubber sealing ring 10. The spherical roller bearing 4 is arranged in the suspension bearing, the two ends of the bearing are respectively provided with the two pressure filling oil cups 5, and a certain amount of lubricating grease is added between the two pressure filling oil cups 5, so that dust in the external environment can be effectively protected from entering the interior, the intermediate bearing is effectively protected from long-term operation and damage, and the service life of the intermediate bearing is prolonged by more than four times through field use of a user.
