[0029] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0030] See also Figure 1 An embodiment of the present application provides a device 1000 , which includes a rotating part 300 , a bearing 200 and a bearing seat 100 .

[0031] The bearing 200 includes an outer ring 210, an inner ring 220, rolling elements and a cage. The outer ring 210, the inner ring 220 and the rotating member 300 are arranged coaxially, and the outer ring 210 and the inner ring 220 are arranged at intervals along the radial direction of the bearing 200, and the outer ring 210 is arranged outside the inner ring 220. The rolling elements and the cage are arranged between the outer ring 210 and the inner ring 220, and the cage can guide the rolling elements to rotate.

[0032] The bearing 200 is limited to the bearing seat 100 so that the outer ring 210 of the bearing 200 is fixed relative to the bearing seat 100, and the rotating member 300 is connected to the inner ring 220 of the bearing 200 so that the rotating member 300 can rotate relative to the bearing seat 100. The outer ring 210 and the bearing seat 100 are limited and matched, and the inner ring 220 and the rotating member 300 are limited and matched. The outer ring 210 and the bearing seat 100 are relatively fixed, and the inner ring 220 and the rotating member 300 can rotate together around the axis of the rotating member 300. The bearing 200 can convert the sliding friction between the rotating member 300 and the bearing seat 100 into rolling friction, thereby reducing the kinetic energy loss of the rotating member 300.

[0033] Specifically, the outer ring 210 is provided with a first through hole, which penetrates the outer ring 210 along the axial direction of the bearing 200. The outer ring 210 includes an outer peripheral surface 2101 and an inner peripheral surface 2102. The outer peripheral surface 2101 and the inner peripheral surface 2102 are arranged opposite to each other along the radial direction of the outer ring 210, and the outer peripheral surface 2101 is arranged on the outside relative to the inner peripheral surface 2102. The outer ring 210 also includes a first end surface 2103, which is arranged on one side of the outer ring 210 along the axial direction.

[0034] The inner ring 220 is provided with a second through hole, which penetrates the inner ring 220 along the axial direction of the bearing 200. The inner ring 220 includes an outer peripheral wall and an inner peripheral wall. The outer peripheral wall and the inner peripheral wall are arranged opposite to each other along the radial direction of the inner ring 220, and the outer peripheral wall is arranged on the outside relative to the inner peripheral wall.

[0035] The rotating member 300 is arranged in the second through hole, and the outer side of the rotating member 300 abuts against the wall of the second through hole. The inner ring 220 is arranged in the first through hole. The outer peripheral wall of the inner ring 220 and the inner peripheral surface 2102 of the outer ring 210 are opposite to each other along the radial direction of the bearing. The inner ring 220 can rotate around the axis of the bearing 200 relative to the outer ring through the retaining frame and the rolling body.

[0036] In the device 1000 provided in the embodiment of the present application, the number of bearings 200 and bearing seats 100 is the same and is at least two, the bearings 200 correspond to the bearing seats 100 one by one, the rotating member 300 is a rotating shaft, and at least one bearing 200 and one bearing seat 100 are respectively provided at the opposite ends of the rotating shaft.

[0037] For example, there are two bearings 200, two bearing seats 100, and one rotating member 300 (i.e., rotating shaft). One end of the rotating member 300 is connected to the inner ring 220 of one of the bearings 200, and the outer ring 210 of the bearing 200 is fixed relative to the bearing seat 100; the other end of the rotating member 300 is connected to the inner ring 220 of another bearing 200, and the outer ring 210 of the bearing 200 is fixed relative to the bearing seat 100. In other examples, the number of bearings 200 and bearing seats 100 can also be other numbers, which is not limited here.

[0038] See also Figure 2 and Figure 3 For the convenience of description, the Y-axis direction is defined as the thickness direction of the bearing seat 100, the Z-axis direction is defined as the height direction of the bearing seat 100, and the X-axis is defined as the length direction of the bearing seat 100. The X-axis, Y-axis, and Z-axis are perpendicular to each other. The directional terms such as "upper", "top", "lower", "bottom", "left", and "right" mentioned in the description of the embodiments of the present application are described based on the directions shown in the accompanying drawings, with the positive direction of the Z-axis being "upper" and "top", the negative direction of the Z-axis being "lower" and "bottom", the positive direction of the X-axis being "right", and the negative direction of the X-axis being "left". It does not constitute a limitation on the bearing seat 100 in the actual application scenario. The "same", "equal", "consistent", or "parallel" used in this article are all allowed to have a certain tolerance.

[0039] In an embodiment of the present application, the bearing seat 100 includes a mounting seat 10 and a rotating stop block 20. The mounting seat 10 is provided with a mounting hole 101. The mounting hole 101 penetrates the mounting seat 10 along the thickness direction of the bearing seat 100, that is, along the Y-axis direction. The mounting hole 101 is used to set the bearing 200. The hole wall surface of the mounting hole 101 is used to abut against the outer peripheral surface 2101 of the outer ring 210 to limit the circumferential rotation of the outer peripheral surface 2101 of the outer ring 210.

[0040] The circumferential direction of the bearing 200 is the Y-axis direction around the bearing seat 100 , the axial direction of the bearing 200 is the Y-axis direction of the bearing seat 100 , and the radial direction of the bearing 200 is the Y-axis direction perpendicular to the bearing seat 100 .

[0041] The rotation stopper 20 can rotate relative to the mounting seat 10 so that the rotation stopper 20 switches between abutting against or releasing the abutment with the first end surface 2103 of the bearing 200 .

[0042] The rotating stopper 20 is rotatably connected to the mounting seat 10. The rotating stopper 20 can be rotated relative to the mounting seat 10 until the rotating stopper 20 and the outer ring 210 are released from abutment, that is, the rotating stopper 20 and the first end face 2103 are released from abutment, and the first end face 2103 of the outer ring 210 faces the rotating stopper 20. When the rotating stopper 20 abuts against the first end face 2103 of the bearing 200, the rotating stopper 20 limits the axial movement of the bearing 200, that is, the bearing 200 can move along the Y-axis direction, the bearing 200 can be evacuated from the mounting hole 101, and the bearing 200 is removed from the mounting seat 10.

[0043] The rotating stopper 20 is rotatably connected to the mounting seat 10. The rotating stopper 20 can rotate relative to the mounting seat 10 until the rotating stopper 20 and the outer ring 210 abut against each other. The rotating stopper 20 limits the axial movement of the bearing 200. The outer ring 210 of the bearing 200 is fixed relative to the mounting seat 10, thereby installing the bearing 200 on the bearing seat 100.

[0044] In the bearing mounting structure provided by the related art, the bearing mounting structure includes an upper fixing seat and a lower fixing seat, and the upper fixing seat and the lower fixing seat are fixedly connected from top to bottom by bolts, and the upper fixing seat and the lower fixing seat are enclosed to form a mounting hole, and the bearing is installed in the mounting hole. The above-mentioned bearing mounting structure is complicated to disassemble, and multiple parts need to be disassembled. It is also necessary to adjust the gap between the upper fixing seat and the lower fixing seat, and the gap is used to ensure that the bearing can rotate stably. Therefore, the bearing mounting structure provided by the related art takes a long time to replace the bearing, which affects the output of the related equipment per unit time and reduces production efficiency. In addition, for the working conditions of frequent disassembly, the upper fixing seat and the lower fixing seat are connected by bolts, and it takes a long time to remove the bolts and it is inconvenient to use; frequent disassembly of the bolts can easily cause the connection between the bolts and the threaded holes to fail, lose the limiting and fixing function, and the service life of the bearing mounting structure is short.

[0045] In the bearing seat 100 provided in the embodiment of the present application, the number of parts in the bearing seat 100 is small. The bearing seat 100 includes a mounting seat 10 and a rotating stopper 20. The mounting seat 10 and the rotating stopper 20 have simple structures and are easy to process and produce. When the bearing seat 100 is installed with the bearing 200, the mounting hole 101 is used to set the bearing 200. The hole wall surface of the mounting hole 101 abuts against the outer peripheral surface 2101 of the bearing 200 to limit the circumferential rotation of the outer peripheral surface 2101 of the bearing 200; the rotating stopper 20 can rotate relative to the mounting seat 10 so that the rotating stopper 20 switches between abutting against or releasing the abutment with the first end surface 2103 of the bearing 200. When installing the bearing, the rotating stopper 20 can rotate relative to the mounting seat 10 until the rotating stopper 20 abuts against the first end surface 2103 of the outer ring 210 to limit the axial movement of the bearing 200, thereby fixing the bearing 200 to the mounting hole 101. When disassembling the bearing 200, the rotating block 20 can be rotated relative to the mounting seat 10 until the rotating block 20 and the first end surface 2103 are no longer abutted, and the bearing 200 can move along its axial direction, and the bearing 200 is withdrawn from the mounting hole 101. Whether installing, disassembling or replacing the bearing 200, the disassembly efficiency is high, and the bearing seat 100 is easy to operate; in addition, the limiting effect of the bearing seat 100 on the bearing 200 is not easy to fail, and the service life is long.

[0046] In the matching mode between the outer ring 210 and the mounting hole 101, the outer ring 210 and the mounting hole 101 are interference fit, the outer diameter of the outer peripheral surface 2101 of the outer ring 210 is larger than the inner diameter of the mounting hole 101, and the outer ring 210 is fixed to the mounting hole 101 by extrusion, so that the outer peripheral surface 2101 abuts against the hole wall surface of the mounting hole 101, thereby limiting the circumferential rotation of the outer ring 210. In other embodiments, the outer peripheral surface 2101 of the outer ring 210 is convexly provided with a positioning key, the hole wall surface of the mounting hole 101 is provided with a groove, the positioning key is arranged in the groove, and the positioning key abuts against the groove surface of the groove, thereby limiting the circumferential rotation of the outer ring 210. In other embodiments, the outer peripheral surface 2101 of the outer ring 210 is provided with a groove, the hole wall surface of the mounting hole 101 is convexly provided with a positioning key, the positioning key is arranged in the groove, and the positioning key abuts against the groove surface of the groove, thereby limiting the circumferential rotation of the outer ring 210.

[0047] In this embodiment, the rotation stopper 20 is disposed on one side of the mounting seat 10, and the rotation stopper 20 is provided with a connecting hole 201, which penetrates the rotation stopper 20 along the thickness direction of the bearing seat 100, that is, along the Y axis. The inner diameter of the connecting hole 201 is smaller than the inner diameter of the mounting hole 101, so as to form a first limiting surface 202 on the side of the rotation stopper 20 facing the mounting seat 10, and the first limiting surface 202 can abut against the first end surface 2103 of the bearing 200.

[0048] The rotating stopper 20 rotates relative to the mounting seat 10 until the hole wall surface of the connecting hole 201 and the hole wall surface of the mounting hole 101 are coaxial, and a step surface is formed between the mounting hole 101 and the connecting hole 201, and the step surface is the first limit surface 202. The first limit surface 202 can abut against the first end surface 2103 to limit the movement of the bearing 200 along the positive direction of the Y axis. In addition, the inner diameter of the connecting hole 201 is larger than the outer diameter of the inner ring 220. Along the radial direction of the mounting hole 101, the hole wall surface of the connecting hole 201 and the outer peripheral wall of the inner ring 220 are spaced apart, which can avoid the inner ring 220 from interfering with the hole wall surface of the connecting hole 201, thereby making the operation of the bearing 200 more stable.

[0049] In this embodiment, the outer ring 210 further includes a second end face 2104 , which is disposed opposite to the first end face 2103 in the axial direction of the outer ring 210 , and the outer peripheral surface 2101 and the inner peripheral surface 2102 are connected between the first end face 2103 and the second end face 2104 .

[0050] The bearing seat 100 further includes a stopper 30, which is fixedly connected to the side of the mounting seat 10 away from the rotating stopper 20. The stopper 30 can abut against the second end surface 2104, so that the outer ring 210 of the bearing 200 is limited between the first limit surface 202 and the stopper 30, thereby limiting the movement of the bearing 200 along the negative direction of the Y axis. In addition, along the radial direction of the mounting hole 101, the stopper 30 and the inner ring 220 are spaced apart, which can avoid interference between the inner ring 220 and the stopper 30, thereby making the operation of the bearing 200 more stable.

[0051] In this example, the limiting member 30 is a limiting washer, which is fixed to the mounting seat 10 by a locking member. Specifically, the limiting washer is provided with a first connection hole, and the side of the mounting seat 10 away from the rotation block 20 is provided with a second connection hole, the first connection hole is directly opposite to the second connection hole, and the locking member passes through the first connection hole and is fixed to the second connection hole, so that the limiting member 30 is fixedly connected to the rotation block 20. In other examples, the limiting member 30 can also be a limiting protrusion, which is provided on the side of the mounting seat 10 away from the rotation block 20, and the limiting protrusion is designed to be integrally formed with the mounting seat 10.

[0052] In some embodiments, see Figure 4 The mounting seat 10 of this embodiment and Figure 1The structure of the mounting seat 10 shown in the embodiment is similar, except that the mounting seat 10 of the present embodiment is not provided with a limiting member 30, and a second limiting surface 102 is provided inside the mounting hole 101 of the present embodiment, and the second limiting surface 102 can abut against the second end surface 2104, so that the outer ring 210 of the bearing 200 is limited between the first limiting surface 202 and the second limiting surface 102. The first limiting surface 202 can abut against the first end surface 2103 to limit the movement of the bearing 200 along the positive direction of the Y axis, and the second limiting surface 102 can abut against the second end surface 2104 to limit the movement of the bearing 200 along the negative direction of the Y axis, thereby axially limiting the outer ring 210 of the bearing 200 to the mounting seat 10.

[0053] Specifically, the mounting hole 101 includes a first sub-groove 1011 and a second sub-groove 1012 opened along the circumference of the hole wall surface thereof, the first sub-groove 1011 and the second sub-groove 1012 are connected along the thickness direction of the bearing seat 100, and the inner diameter of the first sub-groove 1011 is greater than the inner diameter of the second sub-groove 1012. The first sub-groove 1011 is located on the side of the mounting seat 10 facing the rotation stopper 20, and the second sub-groove 1012 is located on the groove bottom surface of the first sub-groove 1011. The second sub-groove 1012 passes through the groove bottom surface of the first sub-groove 1011 and the side of the mounting seat 10 away from the rotation stopper 20, and the second limiting surface 102 is provided on the groove bottom surface of the first sub-groove 1011.

[0054] Along the axial direction of the bearing 200, the groove circumferential surface of the first sub-groove 1011, the groove circumferential surface of the second sub-groove 1012 and the rotating stopper 20 are arranged in sequence. When the rotating stopper 20 presses against the first end face 2103 of the bearing 200, the second limiting surface 102 presses against the second end face 2104 of the bearing 200, and the groove circumferential surface of the second sub-groove 1012 presses against the outer circumferential surface 2101 of the bearing 200.

[0055] In some embodiments, see Figures 1 to 4 The bearing seat 100 also includes a limiting portion 11, which is fixedly connected to the mounting seat 10. The limiting portion 11 is at least partially arranged on the side of the mounting seat 10 facing the rotating stopper 20, that is, the limiting portion 11 is arranged on the side of the mounting seat 10 along the negative direction of the Z axis, that is, the positive projection of the mounting seat 10 and the limiting portion 11 on the ZOY plane is L-shaped.

[0056] The limiting portion 11 is provided with a first abutting surface 111, and the first abutting surface 111 faces the rotation stopper 20. The rotation stopper 20 is provided with a second abutting surface 203. When the rotation stopper 20 rotates relative to the mounting seat 10, the second abutting surface 203 abuts against the first abutting surface 111 to limit the rotation of the rotation stopper 20. When the second abutting surface 203 abuts against the first abutting surface 111, the connecting hole 201 and the mounting hole 101 are coaxially arranged, that is, the hole wall surface of the connecting hole 201 and the hole wall of the mounting hole 101 are coaxial. This arrangement can make the operation of the rotating member 300 and the bearing 200 more stable.

[0057] In some embodiments, please refer to Figures 1 to 4 The first abutting surface 111 is provided with a protrusion 112, and the protrusion 112 is spaced apart from the mounting seat 10 to form a positioning groove 114 between the protrusion 112 and the mounting seat 10. When the rotation block 20 rotates relative to the mounting seat 10 until the rotation block 20 abuts against the first end surface 2103 of the bearing 200, the second abutting surface 203 abuts against the bottom surface of the positioning groove 114 to limit the rotation of the rotation block 20.
