Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a high-temperature resistant bearing for a steel stand hot delivery roller. Background Art

[0002] Steel gantry hot delivery rollers are usually used in high-temperature working environments such as metallurgy, glass manufacturing, blast furnaces, and kilns. These environments are often accompanied by high temperatures, heavy loads, and complex working conditions. Therefore, the high-temperature resistant bearings used here must have excellent high-temperature resistance, load capacity, and stability.

[0003] Existing high-temperature resistant bearings for hot-feed roller tables on steel platforms are mostly high-temperature resistant self-aligning ball bearings, high-temperature resistant deep groove ball bearings, etc. These high-temperature resistant bearings may experience clearance changes at high temperatures, resulting in performance degradation. Therefore, it is necessary to optimize the clearance design so that the high-temperature resistant bearings can remain stable at high temperatures. At the same time, it is necessary to improve the fatigue resistance and service life of the bearings through reasonable preload design. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a high-temperature resistant bearing for a steel stand hot delivery roller, which solves the problem that the existing high-temperature resistant bearings cannot cope with clearance changes.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-temperature resistant bearing for a steel stand hot-delivery roller, comprising a bearing body, the bearing body comprising an outer ring, an inner ring, a retaining frame arranged between the outer ring and the inner ring, and a spiral roller arranged on the retaining frame, a fitting sealing plate is arranged at both ends of the outer ring, the outer diameter of the sealing plate is the same as the outer diameter of the outer ring, a rotating hole with the same diameter as the inner diameter of the inner ring is opened on the inner side of the sealing plate, the sealing plate is fixedly connected to the outer ring by a high-temperature resistant screw, a sealing threaded hole is arranged on the sealing plate, and an outer ring threaded hole corresponding to the sealing threaded hole is arranged on the outer ring.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Such as Figures 1 to 4As shown in the figure, a high-temperature resistant bearing for a hot charging roller path of a steel bench includes a bearing body 1. The bearing body 1 includes an outer ring 101, an inner ring 102, a cage 103 disposed between the outer ring 101 and the inner ring 102, and spiral rollers 104 disposed on the cage 103. Sealing plates 2 are disposed at both ends of the outer ring 101. The outer diameter of the outer side of the sealing plate 2 is the same as the outer diameter of the outer ring 101. A rotating hole 201 with the same inner diameter as the inner side of the inner ring 102 is opened on the inner side of the sealing plate 2. The sealing plate 2 is fixedly connected to the outer ring 101 through high-temperature resistant screws 3. A sealing threaded hole 202 is provided on the sealing plate 2, and an outer ring threaded hole 105 corresponding to the sealing threaded hole 202 is provided on the outer ring 101.

[0021] As Figure 1 shown, the main improvement of the present utility model lies in solving the problem that the existing high-temperature resistant bearings cannot cope with the change of clearance. As Figures 1 to 4 shown, for a high-temperature resistant bearing for a hot charging roller path of a steel bench in the present utility model, when in use, first, the high-temperature resistant screws 3 are placed into the outer ring threaded hole 105 and the sealing threaded hole 202, so that the sealing plate 2 is fixed on the bearing body 1. Subsequently, the sealing plug 206 is opened, and high-temperature grease is added from the oil injection hole 205 between the sealing plate 2 and the bearing body 1. Then, the sealing plug 206 is fixed again and the outer ring 101 is rotated. With the assistance of the dial 207, the added high-temperature grease will enter from the gap between the cage 103 and the spiral rollers 104, so that high-temperature grease is smeared between the spiral rollers 104 and the outer ring 101 and the inner ring 102 to protect the rotation of the bearing. After the bearing is installed, the outer ring 101 is installed in the roll body, and the inner ring 102 is installed on the fixed roll shaft, so that the roll body of the roller path can rotate through the bearing, realizing the transportation of objects by the roller path. Because spiral rollers 104 are selected for the rollers, the bearing will have greater elasticity and radial clearance, which enables the bearing to withstand greater impact loads, and the greater clearance also helps the bearing to maintain stability when the temperature changes.

[0022] As Figure 2 and Figure 3 shown, raised rings 106 are provided near the two ends of the outer ring 101. A groove 203 with the same diameter and a height that fits well with the raised ring 106 is opened on the bottom surface of the sealing plate 2. A cut-off ring 204 with the same diameter as the inner ring 102 is provided on the bottom surface of the sealing plate 2. The outer ring threaded hole 105 is located on the raised ring 106, and the sealing threaded hole 202 is located in the groove 203.

[0023] Specifically, with the cooperation of the raised ring 106 and the groove 203, there will be a neutral gear between the bearing body 1 and the sealing plate 2, so that more high-temperature grease can be stored in the neutral gear, extending the service life of the bearing and avoiding frequent refueling.

[0024] As Figure 4As shown, the sealing plate 2 is provided with an oil filling hole 205 at a position corresponding to the bottom surface of the retaining frame 103 , and a sealing plug 206 is provided at the oil filling hole 205 .

[0025] like Figure 4 As shown, the oil filling hole 205 and the sealing plug 206 are symmetrically arranged on the sealing plate 2 along the central axis of the sealing plate 2.

[0026] Specifically, by opening an oil filling hole 205 and setting a sealing plug 206 on the sealing plate 2, the bearing can be oiled without opening the entire bearing, which is convenient for the staff. The oil filling hole 205 and the sealing plug 206 are symmetrically arranged on the sealing plate 2 along the central axis of the sealing plate 2, which can make the oil filling process uniform.

[0027] like Figure 4 As shown, a shift plate 207 is provided on the bottom surface of the sealing plate 2 at a position corresponding to the bottom surface of the retainer 103 . The lengths of both sides of the shift plate 207 are the same as the diameter of the bottom surface of the retainer 103 . The shift plate 207 is staggered with the oil filling hole 205 .

[0028] like Figure 4 As shown, the dial plate 207 is symmetrically arranged on the bottom surface of the sealing plate 2 along the central axis of the sealing plate 2.

[0029] Specifically, a shift plate 207 is provided on the bottom surface of the sealing plate 2, which can push the high-temperature grease into the gap between the retaining frame 103 and the spiral roller 104, and the shift plate 207 is symmetrically arranged on the bottom surface of the sealing plate 2 along the central axis of the sealing plate 2, which can make the grease more evenly applied.

[0030] like Figures 1 to 3 As shown, a seat hole 107 is provided in the middle of the outer ring 101, so that the outer ring 101 can be easily fixed to the roller body.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
