[0031] Among many mechanical devices, the installation of bearings is a crucial link. The role of bearings is to support the shaft body and reduce the friction of the shaft body during operation, thereby ensuring the normal and efficient operation of the mechanical device.

[0032] In the process of bearing installation, the auxiliary installation of the force receiving member is a common installation method, which is to first set the bearing on the shaft body, then insert the shaft body with the bearing into the force receiving member, and then apply force to the end of the force receiving member beyond the end of the shaft body, so that the force receiving member sets the bearing on the predetermined position of the shaft body. However, due to the diversity of actual application scenarios, the length of the shaft body is often not a single specification, but there are many different lengths. However, the existing force receiving members are mostly fixed in length and cannot be applied to the installation of bearings of shaft bodies of different lengths.

[0033] Based on the above problems, the adjustable-length force-bearing member in this embodiment of the present disclosure can install the bearing on shafts of different lengths, thereby improving the applicability of the bearing mounting assembly.

[0034] Figure 1 The diagram shown is a cross-sectional view of the overall structure of the bearing mounting assembly in an embodiment of this disclosure. Figure 1 In this example, the bearing mounting assembly is used to mount a bearing 40 to a predetermined position on a shaft 50 of different lengths. The bearing mounting assembly includes a driving member 10 and a force-receiving member 20. The driving member 10 is fitted onto the shaft 50 for contact with the bearing 40, which is slidably mounted on the shaft 50. The force-receiving member 20 includes a receiving space 201 for insertion of the shaft 50; the length of the force-receiving member 20 is adjustable; when the shaft 50 is inserted into the receiving space 201, the driving member 10 engages with the force-receiving member 20 so that, when a force is applied toward the bearing 40, a force is applied to the driving member 10 to move the bearing 40 to a predetermined position determined by the length of the force-receiving member 20.

[0035] The advantage of the above configuration is that the length-adjustable force-bearing member 20 can install the bearing 40 at a predetermined position on the shaft 50 of different lengths, thereby improving the applicability of the bearing mounting assembly.

[0036] Exemplarily, the engagement between the driving member 10 and the force-receiving member 20 is implemented as a concave-convex engagement. Further exemplaryly, one of the force-receiving member 20 and the driving member 10 has a protruding engagement portion 21, and the other has a recessed engagement groove 101 that engages with the engagement portion 21. Figure 1 In the enlarged schematic diagram, one end face of the force-bearing member 20 has a protruding annular engaging portion 21, and the drive member 10 has a recessed engaging groove 101 on its wall facing away from the bearing 40 for engaging with the engaging portion 21. Those skilled in the art will understand that the engaging engagement of the force-bearing member 20 with the engaging groove 101 prevents relative displacement between the force-bearing member 20 and the drive member 10 when subjected to an external force directed towards the bearing 40. This ensures that the force-bearing member 20 directly applies the external force directed towards the bearing 40 to the drive member 10, thereby improving the efficiency of bearing 40 installation.

[0037] Secondly, the engagement between the force-bearing component 20 and the engaging groove 101 can prevent the opening of the force-bearing component 20 that abuts against the driving component 10 from being rolled up due to the impact of the external force pointing towards the bearing 40, thereby ensuring that the force-bearing component 20 directly applies the external force pointing towards the bearing 40 to the driving component 10, further improving the efficiency of bearing 40 installation.

[0038] In other embodiments, the wall of the driving member 10 away from the bearing 40 is convex to form a ring-shaped engaging portion 21, and the force receiving member 20 has an end face concave to form an engaging groove 101 for engaging with the engaging portion 21.

[0039] In an example, the force receiving member 20 includes a plurality of connecting tubes 22 connected in sequence along the axial direction. The connecting manner is implemented as at least one of screwing or inserting.

[0040] Figure 2 Fig. 2 shows a cross-sectional view of the force receiving member 20 in an embodiment of the present disclosure. Figure 2 In an example, the connecting manner of the plurality of connecting tubes 22 in sequence is implemented as screwing. In an example, one of the two adjacent connecting tubes 22 forms a threaded groove, and the other forms a screw thread matched with the threaded groove. In this way, the length of the force receiving member 20 formed by splicing the two connecting tubes 22 can be adjusted by relatively rotating the two screwing connecting tubes 22, so as to adapt to the shaft body 50 of different lengths.

[0041] In further examples, the cross section of the threaded groove and the screw thread is rectangular. In further examples, the screw thread is integrally formed with the connecting tube 22 to which it is attached. It can be understood by those skilled in the art that, first, the integrally formed connecting tube 22 and screw thread can improve the strength of the screw thread, avoiding the screw thread from falling off due to the end of the force receiving member 20 abutting against the driving member 10 and the other end being impacted by the external force directed to the bearing 40, thereby causing the force receiving member 20 to be damaged and unable to adjust the length. Second, the screw thread with a rectangular cross section can increase the area of the joint of the two adjacent connecting tubes 22, avoiding the screw thread from being worn when the force receiving member 20 is impacted by the external force directed to the bearing 40, so that the two screwing connecting tubes 22 are loose.

[0042] In other embodiments, the cross section of the threaded groove and the screw thread can also be implemented as trapezoidal.

[0043] Figure 3 Fig. 3 shows a cross-sectional view of another embodiment of the force receiving member 20 in an embodiment of the present disclosure. Figure 3 In an example, the connecting manner of the plurality of connecting tubes 22 in sequence is implemented as inserting. In an example, the force receiving member 20 includes a plurality of connecting tubes 22 connected in sequence along the axial direction by inserting. In further examples, one end of each connecting tube 22 is convex to form an insertion portion 221, for example, a protrusion. The other end is concave to form an inserting portion 222 matched with the insertion portion 221, for example, a groove. In this way, the operator can select a corresponding number of connecting tubes 22 to be inserted, so that the length of the force receiving member 20 after insertion can adapt to the shaft body 50 on which the bearing 40 is installed.

[0044] Figure 4 The diagram shown is a cross-sectional view of another embodiment of the force-bearing member 20 in this disclosure. Figure 4 In this embodiment, the plurality of connecting pipes 22 are implemented to include at least two different lengths. For example, the plurality of connecting pipes 22 include a first connecting pipe 22A and a second connecting pipe 22B of two different lengths. The advantage of this arrangement is that the operator can adapt to the shaft 50 on which the bearing 40 is mounted while avoiding the inconvenience caused by the excessive length of the force-bearing member 20.

[0045] exist Figure 3 and Figure 4 In this embodiment, after the force-bearing component 20 is assembled, the insertion part 221 of the connecting pipe 22 at the bottom engages with the engaging groove 101. That is, the size of the insertion part 221 is adapted to the size of the engaging groove 101.

[0046] In other embodiments, Figure 3 and Figure 4 Alternatively, the insertion portion 221 and the plug portion 222 on two adjacent connecting pipes 22 can be connected by a screw thread. For example, the outer edge of the insertion portion 221 is provided with an external thread, and the inner edge of the plug portion 222 is provided with an internal thread that mates with the external thread.

[0047] Back to Figure 1 In the example, an end cap 30 is detachably connected to the end of the force-receiving member 20 opposite to the driving member 10. Exemplarily, a mounting opening 202 is formed at the end of the force-receiving member 20 opposite to the driving member 10; the end cap 30 includes a force-receiving portion 3131 and a mounting portion 32 that engages with the mounting opening 202. Further exemplaryly, the mounting portion 32 has the same shape as the mounting opening 202. For example, the cross-sectional shape of the mounting opening 202 is circular or rectangular, depending on the shape of the force-receiving member.

[0048] exist Figure 2 , 3 and Figure 4 In this embodiment, the accommodating space 201 is formed by splicing together the cavities of the multiple connecting pipes 22.

[0049] exist Figure 2 , 3 and Figure 4 In this embodiment, the top of the connecting pipe 22 located at the top may also be sealed.

[0050] For example, the force-bearing member 20, the driving member 10, and the end cap 30 are all made of stainless steel or cast iron.

[0051] In summary, the bearing mounting assembly provided by the embodiments of the present disclosure includes a driving member and a force receiving member. The driving member is sleeved on a shaft body for abutting against a bearing which is sleeved on the shaft body in a slidable manner. The force receiving member includes a receiving space for inserting the shaft body. The force receiving member is arranged in a length-adjustable manner. When the shaft body is inserted into the receiving space, the driving member is connected with the force receiving member. When a force is applied to the driving member in a direction pointing to the bearing, the force is applied to the driving member to drive the bearing to a predetermined position determined by the length of the force receiving member. The length-adjustable force receiving member can mount the bearing on shaft bodies with different lengths, thereby improving the applicability of the bearing mounting assembly.

[0052] The above embodiments only exemplarily illustrate the principles and effects of the present disclosure, and are not intended to limit the present disclosure. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present disclosure. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical ideas disclosed by the present disclosure shall still be covered by the protection scope of the present disclosure.
