Technical Field

[0001] This utility model relates to the field of bearing technology, and more specifically, to a bearing with a ball-pad structure. Background Technology

[0002] Currently, when installing linear bearings on the shaft of the engine assembly, the diameter and length of the shaft are relatively large. One shaft requires multiple bearing seats for support. The bearing seats are generally fixed. Due to the influence of assembly position accuracy and dimensional accuracy, there is a tight fit when the shaft and some bearing seats are inserted and installed, which is not easy to adjust and has shortcomings. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a bearing with a ball-pad structure that can adjust the center position and facilitates installation.

Detailed Implementation

[0019] 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.

[0020] like Figure 1 As shown, this embodiment discloses a bearing with a ball-pad structure, including a bearing body 1. A bearing pad 6 is installed on the inner circumferential wall of the bearing body 1. The bearing pad 6 is a tiltable pad, and multiple bearing pads 6 are evenly distributed along the circumference of the bearing body 1. Specifically, a bearing pad base 61 is installed on the inner wall of the bearing body 1. The bearing pad base 61 is inserted into the bearing body 1, and the side of the bearing pad base 61 inserted into the bearing body 1 is spherical. The bearing pad 6 is fixedly installed on the side of the bearing pad base 61 near the center of the bearing body 1. The shaft (not shown in the figure) passes through the inner circle formed by the multiple bearing pads 6. The spherical design of the bearing pad base 61 allows the bearing pad base 61 to rotate and fine-tune itself during insertion of the shaft into the bearing pads 6 and during shaft operation, improving the smoothness of the fit between the shaft and the bearing pads 6.

[0021] The side wall of the bearing pad 6 near the center of the bearing body 1 is coated with a coating 62, which is a Babbitt alloy layer to provide wear reduction and fatigue resistance.

[0022] The bearing body 1 is equipped with an oil spray seat 5, which is located at least partially between two adjacent bearing pads 6. The oil spray seat 5 is provided with an oil spray hole 51. The cooling oil sprayed from the oil spray hole 51 is injected into the inner wall of the bearing pad 6 near the bearing body 1, thereby achieving a cooling effect.

[0023] The bearing body 1 is provided with an oil inlet 15 and connected to multiple oil pipes 14 to supply oil to the oil spray seat 5.

[0024] like Figure 1 As shown, the bearing body 1 includes a bearing body 11 and a bearing body 2 12 below the bearing body 11. The bearing body 11 and the bearing body 2 12 are detachably connected. Since the bearing body 11 and the bearing body 2 12 are separate, when the coating 62 is damaged, it can be quickly disassembled and replaced, which improves work efficiency, shortens maintenance period, and is more economical.

[0025] like Figure 1 As shown, the bearing body 12 has a boss 121 at its bottom, which extends downwards along the bottom surface of the bearing body 12 to form a rectangular plate-like structure. A pad 13 is installed at the bottom of the bearing body 12, and the bottom surface of the pad 13 is spherical. Figure 3 As shown, a support base 7 is inserted and installed at the bottom of the pad 13. The bottom surface of the pad 13 is spherical, which allows the bearing body 1 to be rotated and adjusted during installation to facilitate the insertion of the shaft.

[0026] like Figure 1 As shown, the top of the pad 13 has a groove 131, and the boss 121 is inserted into the groove 131. A pad 2 is installed between the bottom surface of the boss 121 and the inner bottom surface of the groove 131. The pad 2 can be set to different heights so that the height of the center of the inner circle formed by the tile 6 can be changed. This height adjustment facilitates the alignment and insertion of the shaft. The bearing body 12 and the pad 13 are fixed by fasteners 41, and the boss 121 and the pad 13 press the pad 2 together.

[0027] The boss 121 includes sidewalls 1211 on the left and right sides. A second pad 3 is installed on the boss 121, and the second pad 3 is located between the sidewall 1211 and the sidewall of the groove 131. The second pad 3 is fixed to the boss 121 by a fastener 4. The side of the second pad 3 away from the boss 121 is engaged with the sidewall of the groove 131. The left and right positions of the bearing body 12 may change during actual installation. This can be adjusted by setting different left and right thicknesses of the second pad 3 to ensure that the side of the second pad 3 away from the boss 121 is engaged with the sidewall of the groove 131, thereby providing better stability for the bearing body 1.

[0028] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
