Description

Technical Field

[0001] This utility model relates to the technical field of reversing roller bearings for concrete mixing belt conveyors, specifically to a centrifugal self-cleaning belt conveyor reversing roller bearing housing. Background Technology

[0002] In belt conveyor systems used in concrete mixing and mining, the redirecting roller bearings commonly employ a standard UCP bearing housing structure. While this structure is inexpensive and easy to install, it has a fatal flaw:

[0003] 1. Weak sealing: Relying solely on a single-layer oil seal for static sealing, when the moisture content of the conveyed sand and gravel is high, slurry can penetrate the gap between the oil seal and the shaft during the rotation of the drum, leading to grease contamination and failure.

[0004] 2. Lack of drainage: The existing bearing housing is a fully enclosed structure. Mud and water seeping in accumulate in the cavity and form grinding paste, which accelerates the wear of the bearing raceway.

[0005] 3. Insufficient heat dissipation: During continuous operation, the bearing temperature rises, causing the grease to liquefy, which further reduces the sealing force of the seal ring, creating a vicious cycle.

[0006] Therefore, there is an urgent need to design a centrifugal self-cleaning belt conveyor redirecting roller bearing housing to solve the problems of weak and easily damaged seals, inability to drain sewage leading to increased wear, and insufficient heat dissipation causing grease to liquefy and fail when existing technologies are applied to mud or wet environments. Utility Model Content

[0007] In view of the problems existing in the prior art, the purpose of this utility model is to provide a centrifugal self-cleaning belt conveyor redirecting roller bearing housing.

[0008] The technical solution adopted by this utility model to solve its technical problem is: a centrifugal self-cleaning belt conveyor redirecting roller bearing seat, including a bearing seat, a blind cover, a through cover, an oil seal and a mudguard cover. The blind cover and the through cover are fixed on both sides of the bearing seat respectively. The through cover is located on the transmission side and has a shaft hole in the center. An oil seal is installed on the inner side of the through cover, and a mudguard cover is fixedly connected to the outer side of the through cover.

[0009] Specifically, the bottom of the bearing housing is fixedly connected to the belt conveyor, and a bearing is provided on the upper part of the bearing housing, with a drive shaft passing through the bearing.

[0010] Specifically, the blind cover is fixedly connected to the outer end face of the non-transmission side of the bearing housing.

[0011] Specifically, the through cover is sleeved on the drive shaft on the drive side of the bearing seat, the through cover is rotatably connected to the bearing seat, and an annular sealing groove is provided on the inner side of the through cover, with an oil seal embedded in the sealing groove.

[0012] Specifically, the oil seal has a double-ring structure, consisting of an inner sealing ring and an outer dustproof ring. The inner sealing ring faces the inside of the bearing housing, and the outer dustproof ring faces the outside of the cover.

[0013] Specifically, the mudguard has a bowl-shaped structure and is fixedly connected to the outside of the transparent cover. The inner wall of the mudguard is evenly distributed with guide vanes, which are radially protruding. The outer diameter of the mudguard is larger than the diameter of the transparent cover.

[0014] This utility model has the following beneficial effects:

[0015] This utility model designs a centrifugal self-cleaning belt conveyor redirecting roller bearing housing with a triple active protection mechanism: centrifugal spillage: the guide vanes of the mud cover centrifugally throw away mud and slurry, reducing the contact of contaminants at the source; dynamic sealing: the outer dustproof ring of the double-ring oil seal intercepts residual mud and water, and the inner sealing ring locks in the grease, forming a long-lasting sealing barrier with the grease cavity; self-draining: the inclined drainage channel automatically discharges the seepage liquid, completely avoiding liquid accumulation in the cavity; lifespan multiplication effect: the double-ring oil seal resists mud and slurry wear and extends the lifespan; the bearing has an extended service life due to the absence of mud and sand intrusion, reducing costs and increasing efficiency: the heat dissipation fins reduce the bearing's operating temperature and delay grease aging; the drainage channel enables maintenance without disassembly, reducing annual maintenance costs.

[0020] like Figure 1 As shown, a centrifugal self-cleaning belt conveyor redirecting roller bearing housing includes a bearing housing 1, a blind cover 2, a through cover 3, an oil seal 4, and a mudguard cover 5. The blind cover 2 and the through cover 3 are fixed on both sides of the bearing housing 1, respectively. The through cover 3 is located on the transmission side and has a shaft hole in the center. The oil seal 4 is installed on the inner side of the through cover 3, and the mudguard cover 5 is fixedly connected to the outer side of the through cover 3.

[0021] The bearing housing 1 is fixedly installed on the belt conveyor. The outer surface of the bearing housing 1 is provided with heat dissipation fins, which are arranged parallel to the axial direction of the bearing housing 1.

[0022] The blind cover 2 is fixedly sleeved on one end face of the non-transmission side of the bearing housing 1. The blind cover 2 is used to completely prevent contaminants from entering the non-transmission side of the right bearing housing 1 and causing damage to the transmission shaft 6.

[0023] The through cover 3 is fitted onto the end face of the transmission side of the bearing housing 1. The through cover 3 has a shaft hole in the center for the transmission shaft 6 to pass through. The inside of the through cover 3 is equipped with an oil seal 4, which is a double-layer design. The outer oil seal 4 is an outer dustproof ring with a double-ring structure facing outwards from the through cover 3. The outer dustproof ring is used to prevent external contaminants from entering the interior of the bearing housing 1. The inner oil seal 4 is an inner sealing ring with a seal facing inwards from the bearing housing 1. The inner sealing ring is used to seal the grease. The outside of the through cover 3 is also equipped with a mudguard 5, which has a backflow vane. The mudguard 5 is used to throw off splashed contaminants by the centrifugal force generated by rotation to prevent them from entering the interior of the bearing housing 1.
