Description

Technical Field

[0001] This utility model relates to a flange bearing housing, and more particularly to a flange bearing housing that is easy to assemble and disassemble quickly. Background Technology

[0002] Replacing faulty bearings is a crucial part of equipment maintenance. Because the flange bearing housing and bearing are fitted with clearance, friction and vibration between the bearing and the flange bearing housing, and between the bearing and the rollers, cause wear and deformation during machine operation. This causes the bearing housing and bearing to change from a clearance fit to an interference fit. When maintenance personnel discover a problem and need to replace the bearing, even with complete hydraulic tools, it can take a long time to slowly remove the deformed bearing from the flange bearing housing. During the removal process, maintenance personnel must ensure that the bearing and flange bearing housing are subjected to even force at all points to prevent damage to the flange bearing housing during removal. Utility Model Content

[0003] Purpose of the utility model: The purpose of this utility model is to provide a flange bearing housing that is easy to disassemble and assemble quickly, solving the problem in the prior art that when disassembling a bearing, the outer wall support thickness of the bearing is covered by the bearing limiting groove of the flange bearing housing, resulting in no stable support point to push the bearing out during replacement, which takes a long time and damages the flange bearing housing.

[0004] Technical solution: The flange bearing housing of this utility model that is easy to assemble and disassemble includes an intermittent limiting groove. The intermittent limiting groove includes several limiting parts and hollow parts, which are arranged in a circle and spaced apart.

[0005] Furthermore, the central angle of the hollowed-out section is between 15 and 90 degrees.

[0006] Furthermore, the central angle of the hollowed-out portion is not greater than the central angle of the limiting portion.

[0007] Furthermore, the number of the hollowed-out portions and the limiting portions are both even.

[0008] Furthermore, it includes two limiting parts and two hollow parts, with the central angle of both the limiting parts and the hollow parts being 90 degrees.

[0009] Furthermore, it includes two limiting parts and two hollow parts, with the central angle of the hollow parts being 60 degrees and the central angle of the limiting parts being 120 degrees.

[0010] Furthermore, it includes four limiting parts and four hollow parts, with the central angle of the hollow parts being 30 degrees and the central angle of the limiting parts being 60 degrees.

[0011] Beneficial effects: Compared with the prior art, this utility model allows for quick and convenient disassembly of the bearing inside the flange bearing housing during maintenance or malfunction, and is less likely to damage the flange bearing housing, thus reducing maintenance and replacement time and contributing to the reduction of manufacturing costs.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0018] like Figure 1 and Figure 2 The diagram shows a flange bearing housing and its assembly in the prior art. The outer wall support thickness of bearing 2 is covered by the bearing limiting groove 1 of the flange bearing housing. Reference numeral 3 shows the portion of the bearing outer ring support wall thickness covered by the bearing limiting groove of the flange bearing housing. This invention analyzes the assembly and working principle of existing flange bearing housings and bearings, and proposes a flange bearing housing in which the outer ring support wall of bearing 2 is not completely covered by the bearing limiting groove 1. This allows disassembly tools to have a force point to push out bearing 2 from inside the flange bearing housing, while ensuring that the flange bearing housing maintains its original strength and service life during high-speed machine operation.

[0019] This utility model relates to a flange bearing housing. The limiting groove 1 of the flange bearing housing is modified from a closed circle into a perforated section 42 with intermittent central angles ranging from 15 to 90 degrees. The number of perforated sections 42 is determined based on the diameter of the flange bearing housing and the specific conditions. During high-speed operation in rewinding machines or folding machines, it functions as a flange limiter. During disassembly, the intermittent limiting groove 4 of the flange bearing housing is fixed in a vise, and the bearing outer ring support wall can be removed by gently and evenly tapping the perforated portion of the intermittent limiting groove 4.

[0020] The intermittent limiting groove 4 is made of aluminum alloy. The tensile strength of aluminum alloy is about 290 MPa and the yield strength is about 240 MPa, which ensures the strength and service life.

[0021] Example 1

[0022] like Figure 3 As shown, in this embodiment, the intermittent limiting groove 4 includes two limiting parts 41 and two hollow parts 42, the central angle of which is 90 degrees, and the limiting parts 41 and the hollow parts 42 are arranged at intervals.

[0023] Example 2

[0024] like Figure 4 As shown, in this embodiment, the intermittent limiting groove 4 includes two limiting parts 41 and two hollow parts 42. The central angle of the hollow part 42 is 60 degrees, the angle of the limiting part 41 is 120 degrees, and the limiting part 41 and the hollow part 42 are spaced apart.

[0025] Example 3

[0026] like Figure 5 As shown, in this embodiment, the intermittent limiting groove 4 includes four limiting parts 41 and four hollow parts 42. The angle of the hollow parts 41 is 30 degrees, and the angle of the limiting parts 41 is 60 degrees. The limiting parts 41 and the hollow parts 42 are arranged alternately. This embodiment can achieve optimal results, ensuring the strength and cycle of use. When replacing the bearing, the tool is evenly stressed at four symmetrical points, and the bearing and bearing seat will not be damaged due to stress issues.
