[0047] As a preface to the embodiments of the present application, a thrust bearing includes one or more rolling elements, and a cage is usually required to hold the positions of the rolling elements and ensure equal spacing between the rolling elements; however, a thrust bearing without a cage is prone to bumping during the transfer process, is inconvenient for installation and handling, and cannot effectively maintain the integrity of the thrust bearing.

[0048] In view of this, the embodiments of the present application provide a transfer device, aiming to solve at least one of the above technical problems.

[0049] Please refer to the appended Figure 1 to the appended Figure 7 As shown in the accompanying drawings, a transfer device for transferring a thrust bearing 1 according to an embodiment of the present application includes a bearing assembly 2 and a driving assembly 3. The bearing assembly 2 includes a bearing main body 21 and a bearing block 22 movably connected to the bearing main body 21. At least one receiving space capable of accommodating the thrust bearing 1 is provided on the outer side of the bearing main body 21. The bearing main body 21 is provided with a receiving groove 210 communicating with the receiving space. At least a part of the bearing block 22 is located in the receiving groove 210. The driving assembly 3 is at least partially disposed in the bearing main body 21. The bearing block 22 is connected to the driving assembly 3, and the driving assembly 3 is configured to drive the bearing block 22 to move between a first position and a second position. When the bearing block 22 is in the first position, the bearing block 22 is received in the receiving groove 210. When the bearing block 22 is in the second position, at least a part of the bearing block 22 protrudes out of the receiving groove 210 and extends into the receiving space to be capable of carrying the thrust bearing 1.

[0050] It should be understood that the transfer device mentioned in the embodiments of the present application can be arranged inside the shaft hole 10 of the thrust bearing 1 or outside the shaft hole 10 (outside the thrust bearing 1). The present application takes the transfer device arranged inside the shaft hole 10 of the thrust bearing 1 as an example for explanation; in some embodiments, the transfer device is configured to pass through the shaft hole 10 of the thrust bearing 1, and the bearing block 22 can move from inside the shaft hole 10 to the bottom of the thrust bearing 1 and carry the thrust bearing 1. When the transfer device is arranged inside the shaft hole 10 of the thrust bearing 1, the bearing main body 21 of the present application can be a circular structure with a diameter smaller than the inner diameter of the thrust bearing 1; when the transfer device is arranged outside the thrust bearing 1, the bearing main body 21 can be an annular structure with an inner diameter larger than the outer diameter of the thrust bearing 1.

[0051] In this application, by providing a receiving groove 210 on the carrying body 21, the driving assembly 3 can drive the carrying block 22 to be received in the receiving groove 210 or at least partially protrude outside the receiving groove 210. By switching the position of the carrying block 22 through the driving assembly 3, when it is necessary to carry the thrust bearing 1, first, the driving assembly 3 is used to receive the carrying block 22 in the receiving groove 210, so that the carrying assembly 2 can be radially arranged with the thrust bearing 1; secondly, the driving assembly 3 is used to push the carrying block 22 to partially protrude outside the receiving groove 210 and extend into the receiving space to lift the thrust bearing 1, realizing the carrying of the thrust bearing 1, so as to better hold the thrust bearing 1 and facilitate the transfer and assembly of the thrust bearing 1.

[0052] In some embodiments, the driving assembly 3 is rotatably connected to the carrying body 21, and the driving assembly 3 rotates to drive the carrying block 22 to move between a first position and a second position. By rotatably connecting the driving assembly 3 with the carrying assembly 2, the force overcoming the gravity direction of the thrust bearing 1 is converted into a horizontally rotating force. This structure is simple and ingenious. Only by providing a horizontal rotational force of the driving assembly 3 once, the thrust bearing 1 can be stably carried, so as to transfer the thrust bearing 1 more efficiently and with less effort.

[0053] In some embodiments, as shown in Figure 2 the carrying body 21 is provided with a receiving cavity 211, a part of the driving assembly 3 is received in the receiving cavity 211, and the receiving groove 210 communicates with the receiving cavity 211. By providing the receiving cavity 211 on the carrying body 21 to receive a part of the driving assembly 3 in the receiving cavity 211, the overall structure of the transfer device is made more concise, the weight is reduced, and the driving assembly 3 is not easily damaged. The driving assembly 3 will not interfere with the outside during the relative rotation with the carrying body 21, and its safety is higher.

[0054] In some embodiments, the driving assembly 3 includes: a driving member 31 and a transmission member 32. The driving member 31 is rotatably connected to the carrying body 21; the transmission member 32 is connected to the carrying block 22; the driving member 31 rotates relative to the carrying body 21 to drive the transmission member 32 and drive the carrying block 22 to move to the second position. As shown in Figure 2 、 Figure 4As shown, in some embodiments, the driving member 31 includes a turntable 311 which is rotatably connected to the bearing body 21; the transmission member 32 includes a connecting rod 321 which has opposite first and second ends, the first end is rotatably connected to the bearing block 22, and the second end is rotatably connected to the turntable 311; the turntable 311 can drive the connecting rod 321 to rotate so as to drive the bearing block 22 to move between a first position and a second position. By rotating the driving member 31 relative to the bearing body 21 and driving the connecting rod 321, the bearing block 22 is moved between the first position and the second position. Since the connecting rod 321 is directly connected between the bearing block 22 and the driving member 31, the connecting rod 321 mainly functions to transmit power. The working mode of the driving assembly 3 is simpler and more reliable. A similar cam-linkage mechanism is formed between the driving member 31 and the connecting rod 321. Its structure is simple, flexible and reliable, and is not prone to failures. The bearing block 22 can move relative to the receiving groove 210, the power transmission is efficient, and it can bear a relatively high load force.

[0055] In some embodiments, referring to Figure 5 and cooperating with Figure 7 as shown, the driving assembly 3 includes: a turntable 311 and a convex portion 313, the turntable 311 is rotatably connected to the bearing body 21; the convex portion 313 is connected to the outer periphery of the turntable 311; the turntable 311 is used to drive the convex portion 313 to rotate relative to the bearing body 21 so that the convex portion 313 contacts and pushes the bearing block 22 to move to the second position. It should be understood that by directly driving the bearing block 22 with the convex portion 313 and using the arc-shaped contour of the convex portion 313 to drive the bearing block 22 to move to the second position, the driving mode is simple and efficient, and the driving assembly 3 has fewer parts, the structure of the driving assembly 3 is simple, and the maintenance is convenient.

[0056] In some embodiments, the driving assembly 3 further includes a reset structure 33, and the reset structure 33 includes: a guide rod 331 and a reset spring 332, the guide rod 331 is connected to the bearing block 22; the reset spring 332 is sleeved on the guide rod 331, and one end is connected to the bearing body 21 and the other end is connected to the guide rod 331; the reset spring 332 is used to drive the guide rod 331 so as to drive the bearing block 22 to move to the first position; the convex portion 313 pushes the guide rod 331 so as to drive the bearing block 22 to move to the second position. Through the elastic structure composed of the guide rod 331 and the reset spring 332, by using the elastic deformation of the elastic structure and cooperating with the convex portion 313 connected to the outer periphery of the turntable 311, the position switching of the bearing block 22 is realized. This driving mode is simple, efficient and reliable.

[0057] It should be understood that, in the initial state, the reset spring 332 utilizes its own tension and drives the bearing block 22 to be accommodated in the receiving groove 210 through the guide rod 331, so as to ensure that when the transfer device is placed outside the thrust bearing 1, the bearing block 22 will not interfere with the thrust bearing 1, and the bearing block 22 can always be stably accommodated in the receiving groove 210, which has high safety, small space occupation, and is easy to store. When the thrust bearing 1 needs to be transferred, the turntable 311 is driven to rotate relative to the bearing body 21, and the turntable 311 rotates and contacts and pushes the guide rod 331 through the convex portion 313, so that the reset spring 332 contracts, and at the same time, the guide rod 331 drives the bearing block 22 to at least partially protrude outside the receiving groove 210 and extend into the receiving space, so as to effectively carry the thrust bearing 1. When the turntable 311 stops rotating, the extrusion contact between the convex portion 313 and the elastic structure can produce a locking effect, so that the transfer device is kept in a specific position to prevent accidental movement, which helps to increase the stability and safety of the thrust bearing 1 during the transfer process. During the process of the bearing block 22 bearing the thrust bearing 1, the reset spring 332 is always kept in a compressed state. Therefore, when there is no need to bear the thrust bearing 1, it is only necessary to rotate the turntable 311 to misalign the protrusion 313 and the guide rod 331. The bearing block 22 can be automatically received in the receiving groove 210 during the elastic deformation and reset process of the reset spring 332, which is efficient and convenient.

[0058] In some embodiments, the bearing body 21 further includes a limit plate 334, the limit plate 334 is provided with a through hole, and the guide rod 331 is inserted into the through hole; one end of the guide rod 331 is connected to the bearing block 22, and the other end is provided with a locking portion 333; one end of the reset spring 332 is connected to the limit plate 334, and the other end is connected to the locking portion 333. On the one hand, the limit plate 334 can limit the activity space of the reset spring 332, and on the other hand, the through hole provided on the limit plate 334 can provide a movable guide for the guide rod 331; the locking portion 333 can cooperate with the limit plate 334 to limit the activity space of the reset spring 332. The locking portion 333 can be a part of the guide rod 331, or it can be connected to the guide rod 331, and the connection method includes welding, bonding or riveting, etc., which will not be repeated here.

[0059] In some embodiments, see Figure 2 , Figure 4 , Figure 5 as well as Figure 6As shown, the turntable 311 is provided with mounting holes (not shown in the figure). The driving member 31 further includes: a driving rod 312, which is rotatably connected to the bearing body 21. The driving rod 312 passes through the mounting hole and is connected to the turntable 311. The driving rod 312 is used to drive the turntable 311 to rotate relative to the bearing body 21. As shown in the figure, the bearing body 21 is provided with a groove or hole structure for the driving rod 312 to pass through. By rotatably connecting the driving rod 312 to the bearing body 21, the rotation center of the turntable 311 can be positioned. A detachable connection method is adopted between the turntable 311 and the driving rod 312, and the accessories can be replaced to be applicable to different usage scenarios. At the same time, disassembly is easier for storage. In some embodiments, the turntable 311 is provided with mounting holes, and the driving rod 312 passes through the mounting holes and is fixedly connected to the turntable 311. An interference fit can be adopted between the driving rod 312 and the turntable 311, or by providing a flat key groove on the driving rod 312, the driving rod 312 and the turntable 311 can be fixedly assembled through a flat key.

[0060] In some embodiments, please refer to Figures 1 to 4 As shown, the driving member 31 further includes: a rotating handle 314, and the rotating handle 314 is detachably connected to the driving rod 312. The rotating handle 314 adopts a detachable method to achieve easy installation and disassembly, and this driving method is more efficient and labor-saving.

[0061] In some embodiments, please refer to Figure 2 and Figure 4 As shown, the transfer device further includes a limiting member 40. The limiting member 40 is connected to the bearing body 21 and is at least partially located above the receiving space. The limiting member 40 is used to, when the bearing block 22 bears the thrust bearing 1, jointly define the receiving space of the thrust bearing 1 in the up and down directions with the bearing block 22 to limit the thrust bearing 1. By providing the limiting member 40, the thrust bearing 1 carried on the bearing block 22 is prevented from moving further in the height direction, avoiding unstable shaking of the thrust bearing 1 during the transfer process, and improving safety and stability.

[0062] In some embodiments, the driving assembly 3 includes a driving member 31, and the driving member 31 is rotatably connected to the bearing body 21. The limiting member 40 is provided with an assembly hole 400, and the limiting member 40 is sleeved on the driving member 31 through the assembly hole 400. The limiting member 40 is sleeved on the driving member 31. During the process of the bearing block 22 bearing the thrust bearing 1, the limiting member 40 can slide relative to the driving member 31. Therefore, while satisfying the limitation of the thrust bearing 1, it can also adapt to thrust bearings 1 with different sizes and heights. In addition, the bearing height of the thrust bearing 1 by the bearing block 22 can also be adjusted adaptively.

[0063] In some embodiments, the limiting member 40 can move up and down relative to the bearing body 21. When the bearing block 22 bears the thrust bearing 1, the limiting member 40 and the bearing block 22 jointly clamp the thrust bearing 1. Specifically, it should be understood that in some embodiments, the limiting member 40 is in the structure of a circular plate, and is arranged on the driving rod 312 above the bearing body 21 in a way of sleeving with openings, so as to perform movable limiting on the height direction of the thrust bearing 1; it should be understood that in some other embodiments, the limiting member 40 can be fixedly arranged on the bearing body 21 and is located above the bearing block 22; and the way of the movable sleeving of the limiting member 40 in this application can be applicable to thrust bearings 1 with different heights, and has a wider application range. In some embodiments, a protrusion is provided at the top of the limiting member 40. By providing the protrusion, an operator can hold the protrusion to better rotate the driving assembly 3.

[0064] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, the bearing block 22 is provided with an inclined guiding surface 221. When the bearing block 22 moves from the first position to the second position, the guiding surface 221 can move to the bottom of the thrust bearing 1 and lift the thrust bearing 1. It should be understood that the bearing block 22 is provided with an inclined guiding surface 221, and the bottom of the guiding surface 221 is located at the bottom of the thrust bearing 1 and below. By driving the bearing block 22 to move outwards in the radial direction, the guiding surface 221 can move to the bottom of the thrust bearing 1 more flexibly and effectively support the bottom of the thrust bearing 1. In some embodiments, the bearing body 21 is provided with a plurality of receiving grooves 210, and the plurality of receiving grooves 210 are arranged at intervals along the circumferential direction of the bearing body 21; the number of the bearing blocks 22 is multiple, and each bearing block 22 corresponds to a receiving groove 210 in position. Or, the bearing body 21 is in an annular structure or a circular structure, and it can be provided with an annular receiving groove 210. The number of the plurality of bearing blocks 22 can be two or more. The spaced arrangement of the bearing blocks 22 can better bear the thrust bearing 1 and ensure stable force application. In some embodiments, the plurality of bearing blocks 22 are arranged at intervals and opposite to each other in pairs. During the synchronous movement process of the plurality of bearing blocks 22, the arrangement opposite to each other in pairs can cancel the horizontal thrust on the thrust bearing 1 and avoid the unbalanced force on the thrust bearing 1 during the process of jacking up the thrust bearing 1.
