Detailed Implementation

[0013] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 1 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0014] Please see Figures 1-2 This application provides a technical solution for an air expansion shaft bearing housing: an air expansion shaft bearing housing includes a bearing housing 1, a rotating shaft 2 is rotatably connected inside the bearing housing 1, a bearing seat 3 is provided at the end of the rotating shaft 2, the bearing housing 1 is connected to the rotating shaft 2 through a bearing 16, and a cap 17 is provided at one end of the bearing 16 and the cap 17 is fixed on the bearing housing 1.

[0015] Furthermore, the bearing housing 1 is connected to the rotating shaft 2 via a bearing 16. One end of the bearing 16 is provided with a cap 17, which is fixed to the bearing housing 1.

[0016] Specifically, there are two bearings 16, which are connected by two spacers. The cover 17 is fixed to the bearing housing 1 by bolts, which can fix and limit the bearings 16, prevent the bearings 16 from coming off the bearing housing 1, and improve the stability of the rotation of the bearings 16 and the shaft 2.

[0017] The bearing seat 3 consists of two parts: the lower part is the support seat 4, and the upper part is the flip cover 5. V-grooves 6 are symmetrically arranged between the support seat 4 and the flip cover 5. Both ends of the V-grooves 6 of the support seat 4 are provided with clearance grooves 7. Hinge shafts 8 are arranged in the clearance grooves 7. One hinge shaft 8 is connected to the flip cover 5 through a connecting plate 9, and the other hinge shaft 8 is connected to the fixing group 10. The flip cover 5 is fixed to the support seat 4 through the fixing group 10.

[0018] Specifically, the clearance groove 7 allows the connecting plate 9 and the fixing assembly to be cleared, thus facilitating the movement of the connecting plate 9 within the clearance groove 7.

[0019] More specifically, the width of the clearance groove 7 should be consistent with the width of the connecting plate 9 and the swing rod 11 in the fixing group 10, so as to limit the connecting plate 9 and the swing rod 11 and prevent the connecting plate 9 and the swing rod 11 from axially swaying in the clearance groove 7.

[0020] The bottom support 4 is fixed to one end of the rotating shaft 2. The flip cover 5 can rotate around the hinge shaft 8 via the connecting plate 9, which makes it easy for workers to install the air expansion shaft square shaft. Furthermore, the setting of the fixing group 10 allows the flip cover 5 to be fixed on the support 4, so that the V-groove 6 on the support 4 and the flip cover 5 can fix the air expansion shaft square shaft.

[0021] Furthermore, the fixing assembly 10 includes a rocker arm 11, a screw 12, and a pad 13. The rocker arm 11 is installed in the relief groove 7 of the support base 4 and is rotatably connected to the hinge shaft 8. A blind hole is provided on the upper surface of the rocker arm 11. The blind hole is a threaded hole, and a screw 12 is screwed into the threaded hole. The screw 12 is connected to the flip cover 5 through the pad 13.

[0022] Specifically, the width of the rocker arm 11 should be consistent with the width of the clearance groove 7, and the rocker arm 11 can rotate around the hinge pin 8. The flip cover 5 is fixed on the rocker arm 11 by the screw 12 and the pad 13, so that the flip cover 5 cooperates with the support base 4 to fix the air expansion shaft square shaft.

[0023] Furthermore, the flip cover 5 is semi-circular, with a groove at the corresponding screw 12, a pad 13 at the bottom of the groove, and a movable groove 14 at the bottom of the groove corresponding to the swing rod 11.

[0024] Specifically, by setting the movable groove 14 on the flip cover 5, when it is necessary to replace the air expansion shaft square shaft, the screw 12 can be loosened. Note that the screw 12 should not be disengaged from the rocker arm 11. Rotate the rocker arm 11 so that the rocker arm 11 rotates around the hinge shaft 8 as the center, and the screw 12 and the pad 13 are disengaged from the flip cover 5, which makes it convenient for workers to disassemble and clean the air expansion shaft square shaft or replace the air expansion shaft square shaft.

[0025] Furthermore, a semi-circular groove 15 is provided at the bottom of each V-shaped groove 6.

[0026] Specifically, the semi-circular groove 15 prevents the V-groove 6 from easily breaking or cracking when subjected to wear, collision, pressure, or other forces on the corners of the air expansion shaft.

[0027] When using: When it is necessary to install the air shaft, loosen the screw 12, making sure that the screw 12 does not disengage from the rocker arm 11. Rotate the rocker arm 11 so that it rotates around the hinge pin 8, and the screw 12 and the pad 13 disengage from the flip cover 5. Flip the flip cover 5 and the connecting plate 9 around the hinge pin 8. Manually place the square head of the air shaft into the V-groove 6 of the support seat 4. Flip the flip cover 5 to press down on the square head of the air shaft. Rotate the rocker arm 11 so that the screw 12 and the pad 13 move above the flip cover 5. Tighten the screw 12. The bearing seat of one end of the air shaft is now installed. Then repeat the above steps to install the square head of the other side of the air shaft.

[0028] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
