[0033] When the bearing is installed on the shaft for operation, in order to avoid separation of the shaft and the bearing, the connection between the two is relatively tight, and it is difficult to remove the bearing from the shaft, especially for large bearings used for drill collars.

[0034] The utility model provides a portable bearing assembly and disassembly device 100 .

[0035] See also Figures 1 to 5 In one embodiment of the utility model, the portable bearing assembly and disassembly device 100 includes an axial connecting seat 30, a bearing support tube 10 and a linear drive member 20; one end of the axial connecting seat 30 is used to connect one end of the shaft member 300, the bearing support tube 10 is sleeved on the axial connecting seat 30 and is used to accommodate the shaft member 300, one end of the bearing support tube 10 is provided with a clamp 11, the clamp 11 is used to abut against the bearing 200 installed on the shaft member 300, the linear drive member 20 is connected to the other end of the axial connecting seat 30, and the linear drive member 20 is used to drive the bearing support tube 10 to move toward the bearing 200 to separate or connect the bearing 200 and the shaft member 300.

[0036] In the present invention, the shaft 300 can be a large shaft-shaped member for a drill collar, and the bearing 200 can be a large bearing member for a drill collar. The connection between one end of the shaft-shaped connecting seat 30 and one end of the shaft 300 can be a threaded connection, that is, a sub-thread groove can be reserved at one end of the shaft 300, and the end of the shaft-shaped connecting seat 30 connected to the shaft 300 is provided with a female thread groove matching the above-mentioned thread groove, and the two are connected to each other, so that the shaft-shaped connecting seat 30 can be connected to the end of the shaft 300. In addition, the above-mentioned threaded connection method can also be adopted between the other end of the shaft-shaped connecting seat 30 and the linear drive member 20.

[0037] At the same time, since the bearing support tube 10 is sleeved outside the axial connecting seat 30 and the shaft member 300, one end of the bearing support tube 10 is provided with a clamp 11 that can abut the bearing 200. When the linear drive member 20 drives the bearing support tube 10 to slide toward the bearing 200 relative to the axial connecting seat 30 and the shaft member 300, the clamp 11 abutting against the bearing 200 can push the bearing 200 to move on the shaft member 300, thereby removing the bearing 200 from the shaft member 300.

[0038] In addition, when the bearing support tube 10 is sleeved on the other end of the shaft 300, the axial connecting seat 30 and the linear driving member 20 are installed to the other end of the shaft 300. When the linear driving member 20 is started to drive the bearing 200 to move from the other end of the shaft 300 toward the installation position of the bearing 200 on the shaft 300, the bearing 200 can be installed to the installation position of the shaft 300, and the installation of the bearing 200 on the shaft 300 can also be realized.

[0039] The technical solution of the present invention is to connect the shaft member 300 and the linear drive member 20 by setting an axial connecting seat 30, and to set a bearing support tube 10 which is sleeved on the axial connecting seat 30 and can accommodate the shaft member 300. Since one end of the bearing support tube 10 is provided with a clamping head 11 for abutting the bearing 200, when the linear drive member 20 drives the bearing support tube 10 to slide toward the bearing 200 on the axial connecting seat 30, the clamping head 11 can push the bearing 200 to separate the bearing 200 from the shaft member 300, and when the axial connecting seat 30 is installed on the other end of the shaft member and the bearing support tube 10 and the linear drive member 20 are both arranged close to the installation end, the bearing 200 can be pushed in the reverse direction to enable the bearing 200 and the shaft member 300 to be installed. In the case where the stress point of the bearing 200 is small and it is difficult to use tools to operate during removal and installation, the bearing 200 is easy to be removed and installed on the shaft member 300.

[0040] See also Figure 2 , Figure 3 , Figure 4 As shown, in the embodiment of the present utility model, the shaft-shaped connecting seat 30 is provided with a guide groove 31 along the circumferential direction, and the guide groove 31 is extended along the axial direction of the shaft-shaped connecting seat 30;

[0041] The portable bearing assembly and disassembly device 100 also includes a long transverse pin 40, which is radially inserted into the bearing support tube 10 and inserted into the guide groove 31. The output end of the linear drive 20 is connected to the long transverse pin 40 for driving the long transverse pin 40 to slide along the guide groove 31.

[0042] In the above embodiment, when the guide groove 31 is provided on the shaft-shaped connecting seat 30, when the linear driving member 20 drives the long transverse pin 40 to slide along the guide groove 31, the moving stroke of the long transverse pin 40 can be limited. Since the long transverse pin 40 is inserted into the bearing support tube 10, when the linear driving member 20 drives the long transverse pin 40 to slide along the guide groove 31, since the linear driving member 20 and the shaft-shaped connecting seat 30 are relatively fixed, the bearing support tube 10 can be driven to slide relative to the shaft-shaped connecting seat 30, thereby pushing the bearing 200 away from the installation position on the shaft member 300, and realizing the disassembly of the bearing 200.

[0043] Continue reading Figure 2 , Figure 3 , Figure 4 In an embodiment of the utility model, a cavity is opened in the axial connecting seat 30, and the cavity is connected to the guide groove 31. One end of the axial connecting seat 30 connected to the linear driving member 20 is connected to the cavity. The linear driving member 20 is a hydraulic cylinder, and the rod of the hydraulic cylinder penetrates into the cavity and abuts against the long horizontal pin 40.

[0044] In the above embodiment, when the long transverse pin 40 is inserted into the cavity from the guide groove 31 , the rod of the hydraulic cylinder penetrates into the cavity and when driven to move in the cavity, it can abut against the long transverse pin 40 and push the long transverse pin 40 to move along the guide groove 31 .

[0045] Setting the connection portion between the long transverse pin 40 and the linear drive member 20 in the cavity of the axial connecting seat 30 can reduce the connection setting cost and eliminate the need to reserve a connection position between the bearing support tube 10 and the axial connecting seat 30 for the long transverse pin 40 and the linear drive member 20 .

[0046] Continue reading Figure 2 , Figure 3 , Figure 4 In the embodiment of the utility model, the bearing support tube 10 is provided with a pin hole 13 along the circumferential direction, and the long horizontal pin 40 is inserted into the guide groove 31 from the pin hole 13 .

[0047] In the above embodiment, when the long transverse pin 40 is installed by opening a pin shaft hole 13 on the bearing support tube 10, the bearing support tube 10 and the axial connecting seat 30 can be connected and separated by simply inserting and pulling out the long transverse pin 40 into and out of the pin shaft hole 13, thereby facilitating disassembly and assembly between the bearing support tube 10 and the axial connecting seat 30.

[0048] See also Figure 3 , Figure 4 , Figure 5 As shown, in the embodiment of the utility model, the bearing support tube 10 is provided with at least two oppositely arranged pin holes 13, so that one end of the long horizontal pin 40 can pass through the guide groove 31 from the pin hole 13 and pass through the guide groove 31 from the other pin hole 13.

[0049] Such arrangement enables the long transverse pin 40 to be inserted into the guide groove 31 from whichever side of the bearing support tube 10, thereby facilitating the installation of the long transverse pin 40. Meanwhile, the two oppositely arranged pin shaft holes 13 allow both ends of the long transverse pin 40 to be located outside the bearing support tube 10, that is, the long transverse pin 40 completely penetrates the guide groove 31, thereby improving the stability of the long transverse pin 40 sliding along the guide groove 31.

[0050] Continue reading Figure 3 , Figure 4 , Figure 5 In an embodiment of the utility model, a limiting hole 42 is provided at one end of the long horizontal pin 40, a fixing pin 60 is inserted into the limiting hole 42, and a limiting head 41 is provided at the other end of the long horizontal pin 40. The fixing pin 60 cooperates with the limiting head 41 to limit the long horizontal pin 40 to the guide groove 31.

[0051] With such arrangement, when both ends of the long transverse pin 40 are located outside the bearing support tube 10, one end of the long transverse pin 40 can be limited by the limit head 41, and the other end of the long transverse pin 40 can be limited by the fixed pin 60, so that the long transverse pin 40 is limited in the guide groove 31. When the long transverse pin 40 is pushed to slide along the guide groove 31 by the linear drive member 20, the output end of the linear drive member 20 can be prevented from being separated from the long transverse pin 40.

[0052] See also Figure 4 , Figure 5 As shown, in the embodiment of the present utility model, a plurality of pin shaft holes 13 are provided, and the plurality of pin shaft holes 13 are distributed at intervals along the circumference of the bearing support tube 10 .

[0053] In the above embodiment, when a plurality of pin shaft holes 13 are provided, when the pin shaft hole 13 is not aligned with the guide groove 31, the position of the bearing support tube 10 only needs to be slightly rotated and adjusted to align the pin shaft hole 13 with the guide groove 31, thereby facilitating the insertion of the long horizontal pin 40 into the guide groove 31.

[0054] In the above embodiment, when there are multiple groups of pin shaft holes 13, each group includes two relatively arranged pin shaft holes 13, the long horizontal pin 40 can be inserted into the guide groove 31 conveniently, and the long horizontal pin 40 can completely penetrate the guide groove 31, so that the long horizontal pin 40 can slide along the guide groove 31 more smoothly.

[0055] Continue reading Figure 4 , Figure 5 In an embodiment of the utility model, multiple groups of pin shaft holes 13 are provided, and the multiple groups of pin shaft holes 13 are spaced apart along the length direction of the bearing support tube 10, and each group of pin shaft holes 13 includes multiple pin shaft holes 13 spaced apart along the circumference of the bearing support tube 10.

[0056] In the above embodiment, when the length of the axial connecting seat 30 and the bearing support tube 10 is constant, a plurality of groups of pin shaft holes 13 arranged at intervals along the length direction of the bearing support tube 10 can be opened in the bearing support tube 10, so that the distance between the long cross pin 40 and the clamping head 11 can be adjusted, that is, it can adapt to the change of the distance from the end of the shaft 300 to the bearing 200, so that the portable bearing assembly and disassembly device 100 can be adapted to disassembling the bearing 200 on shafts 300 of different lengths.

[0057] See also Figure 2 As shown, in the embodiment of the utility model, the portable bearing assembly and disassembly device 100 further includes a guide sleeve 50, and the guide sleeve 50 is arranged between the bearing support tube 10 and the shaft-shaped connecting seat 30;

[0058] The long transverse pin 40 is inserted into the guide sleeve 50 from the pin shaft hole 13 so that the guide sleeve 50 and the bearing support tube 10 are relatively fixed.

[0059] In the actual application scenario of the utility model, there is a certain gap between the bearing support tube 10 and the axial connecting seat 30. The guide sleeve 50 can be filled in the gap. When the linear drive member 20 drives the bearing support tube 10 to slide along the axial connecting seat 30, it can provide support for the movement of the bearing support tube 10 and prevent the bearing support tube 10 from shaking relative to the axial connecting seat 30.

[0060] See also Figure 4 , Figure 5 In the embodiment of the utility model, a weight-reducing groove 12 is formed through the bearing support tube 10, and a plurality of weight-reducing grooves 12 are provided and distributed at intervals along the surface of the bearing support tube 10;

[0061] And / or, the bearing support tube 10 is made of carbon fiber or aramid fiber.

[0062] In the above embodiment, a weight-reducing groove 12 may be provided on the bearing support tube 10 to reduce the weight of the bearing support tube 10, or the bearing support tube 10 may be made of carbon fiber or aramid fiber, or both of the above methods may be used. Such a configuration can reduce the weight of the bearing support tube 10, and when the portable bearing assembly and disassembly device 100 is applied to a large-volume shaft 300 such as a drill collar, it is convenient for an operator to sleeve the bearing support tube 10 on the shaft-shaped connecting seat 30, thereby reducing the assembly burden of the operator.

[0063] The above are only exemplary embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
