1. Bearing seat

Referring to fig. 1-3, fig. 2 is a schematic structural diagram of an embodiment of a support frame, a bearing seat, a spherical bearing and a rotating shaft according to the present application; fig. 3 is a schematic sectional view of the bearing seat of fig. 2 taken along line I-I'. The bearing assembly 30 includes a bearing housing 31 and a spherical bearing 32, the spherical bearing 32 being disposed in the bearing housing 31, and one end of the rotating shaft 20 being coupled with the spherical bearing 32 such that one end of the rotating shaft 20 is mounted in the bearing assembly 30.

The bearing seat 31 comprises a bearing mounting part 311, a support mounting part 312 and a connecting part 313, wherein the axial direction of the bearing seat 31 is D1, the radial direction of the bearing seat 31 is D2, and the axial direction D1 of the bearing seat 31 and the radial direction D2 of the bearing seat 31 are vertically arranged.

The bearing mounting portion 311 is provided with an accommodating chamber 314 for accommodating the spherical bearing 32 in the axial direction D1 of the bearing housing 31, i.e., the direction of the central axis of the accommodating chamber 314 is the same as the axial direction D1 of the bearing housing 31, so that the accommodating chamber 314 and the bearing mounting portion 311 are coaxially arranged. The spherical bearing 32 is mounted within the receiving cavity 314, and the spherical bearing 32 rotates within the receiving cavity 314.

The support mounting portion 312 is disposed on the periphery of the bearing mounting portion 311, and is spaced apart from the bearing mounting portion 311 in a radial direction D2 of the bearing housing 31. Wherein the support mounting part 312 may be disposed around the bearing mounting part 311 such that the bearing mounting part 311 is disposed within the support mounting part 312. Since the support mounting portion 312 is spaced apart from the bearing mounting portion 311 along the radial direction D2 of the bearing housing 31, the connecting portion 313 is used for connecting the bearing mounting portion 311 and the support mounting portion 312, that is, the connecting portion 313 is disposed between the bearing mounting portion 311 and the support mounting portion 312, and the support mounting portion 312 is connected to the bearing mounting portion 311 through the connecting portion 313.

The support frame 10 is provided with a mounting hole 11, the mounting hole 11 may be a flanged hole, and the support mounting portion 312 of the bearing seat 31 is inserted into the mounting hole 11 of the support frame 10, so that the support mounting portion 312 is disposed in the mounting hole 11 of the support frame 10.

The bearing mounting portion 311, the support mounting portion 312, and the connecting portion 313 are integrally formed, and the integral forming may mean that the material is finished by a single process.

Compared with the inner seat core and the outer seat sleeve of the existing bearing seat which are made of two different materials, the bearing seat 31 of the application is made of a single homogeneous material, and the production difficulty is reduced. In addition, since the bearing mounting portion 311, the support mounting portion 312, and the connecting portion 313 are integrally formed, the production efficiency is improved, the damping effect of the bearing housing 31 is improved, and better elasticity is provided.

2. Bearing mounting part

The rotating shaft 20 is coupled at one end thereof to the spherical bearing 32, i.e., one end of the rotating shaft 20 is fixed to the spherical bearing 32, so that the rotating shaft 20 and the spherical bearing 32 are rotated simultaneously. Therefore, the guide hole 315 serves to guide the spherical bearing 32 together with the rotating shaft 20 into the receiving cavity 314, so that the spherical bearing 32 and the rotating shaft 20 rotate within the receiving cavity 314. The sealed oil chamber 316 is used for storing lubricating oil, and the lubricating oil is used for reducing friction between the spherical bearing 32 and the wall of the accommodating chamber 314, so that functions of lubrication, cooling, rust prevention, shock absorption and the like are realized.

Alternatively, the bearing mounting portion 311 may form a first stopper surface 317 at a junction of the guide hole 315 and the accommodating chamber 314, and a second stopper surface 318 at a junction of the sealed oil chamber 316 and the accommodating chamber 314, and the spherical bearing 32 may be stopped between the first stopper surface 317 and the second stopper surface 318 along the axial direction D1 of the bearing housing 31, so as to prevent the spherical bearing 32 and the rotating shaft 20 from entering the guide hole 315 or the sealed oil chamber 316 when rotating in the accommodating chamber 314.

Optionally, at least a portion of the hole section of the guiding hole 315 is disposed as a first frustum, and the cross section of the first frustum is gradually reduced in a direction toward the accommodating cavity 314, that is, the hole wall of at least a portion of the hole section of the guiding hole 315 is disposed as an inclined plane, so that the hole wall of the guiding hole 315 is provided with a guiding inclined plane to facilitate guiding the spherical bearing 32 into the accommodating cavity 314. Wherein the diameter of the guiding hole 315 close to the accommodating cavity 314 is smaller than the diameter of the guiding hole 315 far from the accommodating cavity 314. In other embodiments, the guiding hole 315 may be arranged in a first frustum.

The sealed oil chamber 316 is further provided for accommodating one end of the rotating shaft 20, i.e., one end of the rotating shaft 20, through the spherical bearing 32, within the sealed oil chamber 316.

Because the cross section of at least part of the cavity section of the sealed oil cavity 316 is gradually reduced in the direction towards the accommodating cavity 314, at least part of the cavity section of the sealed oil cavity 316 is arranged in a second cone, the cross section of the second cone is gradually increased in the direction away from the accommodating cavity 314, namely the area of one end of the sealed oil cavity 316 away from the accommodating cavity 314 is suddenly changed, and the end of the rotating shaft 20 can be prevented from scraping the bearing seat 31 in the case of inclination; in addition, the volume of the oil seal chamber 316 can be increased, and the storage space of the lubricating oil is further increased.

A rib 320 is formed between adjacent two of the damping grooves 319 to increase the strength of the bearing mounting portion 311.

As shown in connection with fig. 3, in the axial direction D1 of the bearing seat 31, the geometric center 329 of the connecting portion 313 is offset from the geometric center 328 of the accommodating chamber 314, for example, the geometric center 329 of the connecting portion 313 is located at the geometric center 328 of the accommodating chamber 314 and is spaced along the axial direction D1 of the bearing seat 31. The rotating shaft 20 is pressed by the connecting portion 313 under the action of gravity, and the geometric center 329 of the connecting portion 313 is arranged in a manner of being offset compared with the geometric center 328 of the accommodating cavity 314, so that the connecting portion 313 can have a buffering effect on the rotating shaft 20 under the condition that the rotating shaft 20 rotates at a high speed, the generation of abnormal sound is reduced, and the rotating stability of the rotating shaft 20 is improved.

As shown in fig. 3, the inner wall of the accommodating chamber 314 is provided with a plurality of first ribs 321, and the first ribs 321 are provided at intervals in the axial direction D1 of the bearing seat 31 and are configured to abut against the outer circumferential surface of the spherical bearing 32.
