Technical Field

[0001] This utility model relates to a bearing housing, and more particularly to a cable reel anti-deformation bearing housing, belonging to the field of cable reel technology. Background Technology

[0002] In environments such as power construction, mining, and factories, cable reels are used frequently. Robust and reliable bearing housings are an important guarantee to prevent cable reels from jamming, shaft breakage, or accidents.

[0003] Currently, in the use of bearing housings, in order to avoid damage and deformation of the bearing housing due to increased frictional resistance and heat generation when the bearing rotates under high load, a lubricating oil injection hole is opened on the top of the bearing housing. However, in actual use, it is not possible to automatically add lubricant according to the usage conditions, which reduces its practicality.

[0004] To address this issue, a cable reel anti-deformation bearing housing was designed. Utility Model Content

[0032] Example 1

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a cable reel anti-deformation bearing housing, including a base 1, an upper cover 2 bolted to the top of the base 1, and a positioning hole 3 opened at the end of the base 1.

[0034] The base 1 is equipped with a bolt positioning reinforcement mechanism 4 at the middle position of both ends;

[0035] A lubricating oil tank 5 is provided at the middle position of the top of the cover 2. The capacity of the lubricating oil tank 5 is 50ml-100ml. A guide groove 6 is provided inside the cover 2. Oil holes 7 are evenly provided on the inner side of the guide groove 6. The bottom end of the oil holes 7 is connected to the bottom of the cover 2.

[0036] The guide groove 6 has a depth of 5-8mm and a width of 10-15mm. The oil hole 7 has a diameter of 1-2mm and a spacing of 20-30mm, ensuring that the lubricating oil is evenly distributed in the guide groove 6 and drips evenly from each oil hole 7 to the bearing.

[0037] An injection mechanism 8 is provided on the inner top of the upper cover 2, and the injection mechanism 8 is connected to the lubricating oil tank 5 and the guide groove 6.

[0038] Before use, the base 1 is fixed to the end plate or bracket of the cable reel with bolts. After the bolts are tightened through the positioning hole 3, the bolts are squeezed and locked again by the reinforcing mechanism 4. During use, the lubricating oil tank 5 contains lubricating oil. When the bearing inside the bearing housing is well lubricated, the bearing friction resistance is small and will not cause the bearing housing to overheat. However, when the lubricating oil is insufficient and the bearing friction resistance increases, the bearing will heat up and the heat will be transferred to the bearing housing. At this time, the injection mechanism 8 will automatically discharge the lubricating oil inside the lubricating oil tank 5 into the guide groove 6 and then drip from the oil hole 7 to lubricate the bearing.

[0039] Example 2

[0040] The solution in Example 1 will be further described below with reference to its specific working method.

[0041] like Figure 4 As shown, in a preferred embodiment, based on the above method, the reinforcement mechanism 4 further includes a sliding hole 401, a pressing block 402, a threaded hole 403, and a screw 404. The sliding hole 401 is opened between two sets of positioning holes 3 and is located on the vertical line of the line connecting the two sets of positioning holes 3. The threaded hole 403 is opened on the end face of the base 1 and is connected to the interior of the sliding hole 401. The pressing blocks 402 are slidably arranged at both ends inside the sliding hole 401. The two sets of pressing blocks 402 are made of 304 stainless steel and have a tapered angle of 60°. The ends of the pressing blocks 402 are in contact with each other, and the contact ends of the pressing blocks 402 are both tapered. The screw 404 is installed in the internal thread of the threaded hole 403.

[0042] Before fixing the bearing housing, insert two sets of extrusion blocks 402 into the sliding hole 401 through the positioning hole 3. The conical heads of the two sets of extrusion blocks 402 fit together. Then, use bolts to tighten and fix the bearing housing. After fixing, rotate the screw 404. The screw 404 will contact the conical head of the extrusion block 402 and apply a force towards the bolt to the extrusion block 402. The end of the extrusion block 402 contacts the outside of the bolt to strengthen the bolt.

[0043] like Figure 4 As shown, in a preferred embodiment, based on the above method, the end of the extrusion block 402 away from the screw 404 is arc-shaped, and anti-slip texture is provided on the arc-shaped end face. The radius of the arc-shaped end face is 5-8mm, and the depth of the anti-slip texture on the arc-shaped end face is 0.5-1mm, with a spacing of 2-3mm. The arc-shaped design of the end of the extrusion block 402 can increase the contact area with the bolt and improve the stability of the fixation.

[0044] like Figure 2 As shown, in a preferred embodiment, based on the above method, the guide groove 6 is further shaped as a semi-circle, and the oil hole 7 is perpendicular to the inner side of the guide groove 6. By opening multiple sets of oil holes 7, lubricating oil can be discharged evenly for rapid lubrication.

[0045] like Figure 3 As shown, in a preferred embodiment, based on the above method, the injection mechanism 8 further includes a transfer chamber 801, a through hole 802, a vertical plate 803 and a bimetallic strip 804. The transfer chamber 801 is opened on the inner top of the upper cover 2, and the top of the transfer chamber 801 is provided with a through hole 802 that communicates with the interior of the lubricating oil tank 5.

[0046] The diameter of the through hole 802 is 2mm-3mm. The flow rate of the lubricating oil is adjusted by controlling the size of the diameter of the through hole 802, so that the lubricating oil drips from the through hole 802 at a rate of 5-10 drops per minute.

[0047] The two ends of the transfer chamber 801 are connected to the guide groove 6. A vertical plate 803 is vertically installed in the middle of the transfer chamber 801. Bimetallic strips 804 are horizontally installed at both ends of the vertical plate 803. The bimetallic strips 804 are located at the bottom of the through hole 802 and block the bottom of the through hole 802. The threshold temperature of the bimetallic strip 804 is set to 70℃. It is a bimetallic strip composed of iron-nickel alloy and copper alloy.

[0048] When the temperature of the bearing housing exceeds the threshold of the bimetallic strip 804, the bimetallic strip 804 will bend downwards, releasing the blockage of the through hole 802. The lubricating oil inside the lubricating oil tank 5 will fall into the transfer tank 801 through the through hole 802 and then flow into the guide groove 6. When the temperature drops, the bimetallic strip 804 will reset and re-block the through hole 802. The rate of lubricating oil flow is affected by the diameter of the through hole 802.

[0049] like Figure 3 As shown, in a preferred embodiment, based on the above method, a sealing plug 805 is fixed to the top of each bimetallic strip 804. The top of the sealing plug 805 is inserted into the interior of the through hole 802. The sealing plug 805 is made of high-temperature resistant rubber, and its top diameter is 0.5mm smaller than the diameter of the through hole 802, and its height is 3-5mm. This ensures that it can be tightly inserted into the through hole 802 to achieve a seal, and can also be smoothly disengaged from the through hole 802 when the bimetallic strip 804 is deformed. The use of the sealing plug 805 can improve the sealing effect of the through hole 802 during use.

[0050] like Figure 1 As shown, in a preferred embodiment, based on the above method, the top of the lubricating oil tank 5 is further threaded with a sealing cap, and the top of the sealing cap is provided with a transparent plate. The use of the transparent plate makes it convenient to observe the amount of lubricating oil so that it can be added in time.

[0051] Example 3

[0052] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0053] Before installing the bearing housing, insert two sets of extrusion blocks 402 into the sliding hole 401 through the positioning hole 3, with the conical ends of the two sets of extrusion blocks 402 fitting together. Then, tighten the bearing housing with bolts. After fixing, rotate the screw 404. The screw 404 will contact the conical end of the extrusion block 402 and apply a force towards the bolt to the extrusion block 402. The end of the extrusion block 402 contacts the outside of the bolt, reinforcing the bolt. During use, the lubricating oil tank 5 stores lubricant, ensuring good lubrication of the bearing inside the bearing housing. Under normal conditions, the bearing's frictional resistance is small, preventing the bearing housing from overheating. However, when lubricating oil is lacking and the bearing's frictional resistance increases, the bearing will generate heat, which will be transferred to the bearing housing. When the bearing housing's temperature exceeds the threshold of the bimetallic strip 804, the bimetallic strip 804 will bend downwards, releasing the blockage of the through hole 802. The lubricating oil inside the lubricating oil tank 5 will fall into the transfer chamber 801 through the through hole 802 and then flow into the guide groove 6 to lubricate the bearing. When the temperature drops, the bimetallic strip 804 will reset and re-block the through hole 802.

[0054] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
