Description

Technical Field

[0001] This utility model relates to the technical field of belt conveyors, specifically to a bearing housing and a mold for processing the bearing housing. Background Technology

[0002] Idler rollers are mainly used to support the conveyor belt and the materials carried on it. Their importance cannot be underestimated. They are the core components for the smooth operation of belt conveyors. The quality of idler rollers is related to the normal operation of the entire belt conveyor, the length of its service life, and the level of energy consumption. They play an important role in the efficiency and economy of the entire conveying operation.

[0003] Inside a typical bearing housing, the bearing, seals, and bearing end caps are assembled sequentially from the inside out. During bearing installation, if... Figure 1 As shown, the inner end face of the bearing, especially the inner ring end face, is in close contact with the bearing housing. During long-term operation, the inner ring of the bearing is prone to high-intensity friction with the surface of the bearing housing. This friction problem not only affects the sealing performance of the idler, but may also cause a series of faults such as idler jamming and deviation, which greatly reduces the stability and reliability of transportation operations. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a bearing housing and a mold for processing the bearing housing, which can set a gap between the end face of the bearing inner ring and the bearing housing to avoid friction between the bearing and the bearing housing, thereby ensuring the performance of the idler roller and extending its service life.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A bearing housing includes a cylindrical body for holding a bearing. An end plate is provided on one side of the cylindrical body. A central hole is provided in the center of the end plate. A groove is provided on the inner surface of the end plate. The central hole and the groove are coaxially arranged.

[0007] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0008] Compared to traditional bearing housings, this utility model adds a groove to the inner side of the bearing housing, which can space the inner ring of the bearing installed inside the bearing housing from the bearing housing, avoiding the end face of the bearing inner ring from abutting against the bearing housing, effectively avoiding friction between the bearing and the bearing housing, extending the service life of the bearing and the bearing housing, ensuring the sealing performance of the idler roller, and ensuring smooth and reliable operation of the transportation operation.

[0009] As a preferred embodiment, a further technical solution of this utility model is:

[0010] Preferably, a protrusion is provided on the outer surface of the end plate at the position corresponding to the groove, which can improve the strength of the bearing seat.

[0011] Preferably, the first groove is a circular structure, and the inner diameter of the first groove is larger than the outer diameter of the inner ring of the bearing and smaller than the inner diameter of the outer ring of the bearing.

[0012] This utility model also discloses a mold for processing bearing seats, including an upper mold and a lower mold. The upper end face of the lower mold is provided with a protrusion that matches the groove on the bearing seat, and the lower end face of the upper mold is provided with a groove.

[0013] Compared with the prior art, the outstanding features of this utility model, which adopts the above technical solution, are:

[0014] The upper and lower dies are used to further process the already formed bearing housing. A groove is punched into the end plate of the bearing housing, which is accurately positioned and can quickly process the bearing housing.

[0015] The depth of groove two is greater than the height of protrusion two. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] A type of bearing housing, such as Figure 2 , 3 As shown, the bearing housing includes a cylindrical body 1 for placing the bearing. One end of the cylindrical body 1 is provided with an end plate 2, and the other end extends with an outer edge 3. The end plate 2, the cylindrical body 1 and the outer edge 3 are integral structures. A central hole 4 is provided in the center of the end plate 2 for the central shaft to pass through.

[0024] The inner surface of the end plate 2 is provided with a circular groove 5, and the outer surface of the end plate 2 is provided with a protrusion 6 corresponding to the circular groove 5. The groove 5 is connected to the surface of the end plate 2 through a transition surface 9. The inner diameter of the groove 5 is larger than the outer diameter of the bearing inner ring 7 and smaller than the inner diameter of the bearing outer ring 8, so as to ensure that there is a gap between the end face of the bearing inner ring 7 and the groove 5 on the inner side of the end plate 2, so that the end face of the bearing inner ring 7 will not come into contact with the end plate 2, thereby avoiding friction between the end face of the bearing inner ring 7 and the end plate 2.

[0025] In this embodiment, the central axis of the central hole 4 is coaxial with the central axis of the circular groove 5.

[0026] In this embodiment, the integrally formed bearing housing (the integrally formed bearing housing end plate 2 does not have a groove) is stamped, such as... Figure 4 , Figure 5 As shown, the stamping die consists of an upper die 10 and a lower die 11. The lower die 11 is clearance-fitted with the cylinder. The upper end face of the lower die 11 is provided with a protrusion 12 that matches the groove 5. The lower end face of the upper die 10 is provided with a groove 13. The depth of the groove 13 is greater than the depth of the protrusion 12.

[0027] The upper die 10 and the lower die 11 are respectively provided with through holes along their respective circumferences. The upper die 10 and the lower die 11 are respectively provided with threaded holes 14 connected to the through holes along their respective central axes. The upper die 10 and the lower die 11 are respectively connected to the stamping equipment through the through holes and fastened by bolts placed in the threaded holes 14.

[0028] In this embodiment, the upper die 10 and the lower die 11 are installed on the stamping forming equipment, and the central axis of the upper die 10 is aligned with the central axis of the lower die 11. After the equipment is installed and debugged, the one-piece bearing seat with the opening facing down is fitted onto the lower die 11. Then the forming equipment is started, and the upper die 10 moves down to press the end plate 2 of the bearing seat, thus completing the stamping process.

[0029] Compared to traditional bearing housings, this utility model adds a groove to the inner side of the bearing housing, which can space the inner ring of the bearing installed inside the bearing housing from the bearing housing, avoiding the end face of the bearing inner ring from abutting against the bearing housing, effectively avoiding friction between the bearing and the bearing housing, extending the service life of the bearing and the bearing housing, ensuring the sealing performance of the idler roller, preventing the idler roller from jamming, and ensuring smooth and reliable operation of the transportation operation.

[0030] The above description is merely a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
