Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically a tapered roller bearing. Background Technology

[0002] Currently, mining and transportation in mines utilize large-scale mining equipment, such as coal mining machines and mining trucks. To ensure stable equipment operation, periodic shutdowns for inspection and maintenance are necessary. While components such as shafts and gears can be remanufactured, bearings, due to the inability to directly inspect internal wear, still require complete scrapping and replacement. Consequently, the market demand for repairable and remanufactured bearings is increasing.

[0003] Large tapered roller bearings are mostly used in critical positions of mining equipment, and these bearings are also the most expensive in the entire machine. In a normal tapered roller bearing, the rolling elements, cage, and inner ring are not separable, making it impossible to determine the internal wear of the bearing after disassembly, thus requiring replacement of the entire bearing. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a tapered roller bearing that, without affecting the normal performance of the bearing, allows for detachment and disassembly, enabling maintenance personnel to directly inspect the internal wear of the bearing.

[0005] To achieve the above objectives, the present invention provides a tapered roller bearing, comprising an outer ring, an inner ring, a small flange on the inner ring, and a cage assembly; a large flange is provided on the large end face of the inner ring; the small flange on the inner ring is operably associated with the inner ring; the cage assembly is disposed between the outer ring and the inner ring; the cage assembly is limited by the small flange and the large flange on the inner ring.

[0006] Furthermore, one end of the retainer assembly contacts the inner small flange, and the other end contacts the large flange.

[0007] Furthermore, the cage assembly is disposed within the inner raceway of the inner ring.

[0008] Furthermore, the cage assembly is provided with a cage seat, through which the tapered rollers pass and are connected to the cage cover.

[0009] Furthermore, the small end face of the inner ring is provided with a threaded hole.

[0010] Furthermore, there are at least two threaded holes, which are evenly distributed on the inner ring small flange.

[0011] Furthermore, the inner ring small flange is provided with a countersunk hole corresponding to the threaded hole.

[0012] Furthermore, it also includes bolts that pass through countersunk holes and engage with threaded holes.

[0013] The beneficial effects of this utility model are as follows: The bearing design of this application adopts a split structure, which does not affect the normal performance of the bearing. The bearing can be separated and disassembled, and maintenance personnel can directly check the internal wear of the bearing. Individual parts can also be replaced, which truly realizes that this type of bearing can be repaired and remanufactured, greatly saving maintenance costs. Attached Figure Description

[0015] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0016] like Figure 1 As shown, an embodiment of the present invention discloses a tapered roller bearing 420, comprising an outer ring 100, an inner ring 200, an inner ring small flange 300, and a cage assembly 400; a large flange 210 is provided on the large end face of the inner ring; the inner ring small flange 300 is operably associated with the inner ring 200; the cage assembly 400 is disposed between the outer ring 100 and the inner ring 200; the cage assembly 400 is limited by the inner ring small flange 300 and the large flange 210.

[0017] In one embodiment, one end of the retainer assembly 400 is in contact with the inner small flange 300, and the other end is in contact with the large flange 210.

[0018] In one embodiment, the cage assembly 400 is disposed within the inner raceway of the inner ring 200.

[0019] In one embodiment, the cage assembly 400 is provided with a cage seat 410 through which tapered rollers 420 pass and are linked to a cage cover 430.

[0020] In one embodiment, the small end face of the inner ring 200 is provided with a threaded hole 220.

[0021] Furthermore, there are at least two threaded holes 220, which are evenly distributed on the inner ring small flange 300.

[0022] In one embodiment, the inner ring small flange 300 is provided with a countersunk hole 310 corresponding to the threaded hole 220.

[0023] In one embodiment, a bolt 500 is also included, which passes through the countersunk hole 310 and engages with the threaded hole 220.

[0024] The aforementioned tapered roller 420 bearing is a separable large tapered roller 420 bearing. The outer ring 100, cage assembly, and inner ring 200 can be separated from each other. The inner ring small flange 300 and the inner ring are changed to a two-piece structure, which is connected together by bolts 500 during use. During maintenance, the bolts 500 are removed, the inner ring small flange 300 is removed, and the cage and rolling element assembly can be directly removed. The operator can directly check the internal wear of the bearing. At the same time, if the inner ring 200 or the outer ring 100 can no longer be used, single parts can be replaced, which greatly reduces maintenance costs.

[0025] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
