Description

Technical Field

[0001] This application relates to the field of bearing support technology, and in particular to a high-strength bearing support. Background Technology

[0002] Bearing housings are structural components used in industrial equipment to support and install bearings. They are also commonly referred to as "bearing housings" or "bearing supports". Bearing housings are needed in equipment such as electric motors, fans, pumps, and speed reducers to support components such as motor shafts and rotor shafts.

[0003] However, existing technologies still have the following problems:

[0004] Existing bearing support technology has many shortcomings in achieving precise fit and axial positioning between the rotating shaft and the bearing ring, and in ensuring efficient transmission between the rotating shaft and external components. Traditional designs cannot ensure precise fit between the bearing ring and the rotating shaft, resulting in misalignment during operation, which exacerbates wear between components and shortens service life. During equipment operation, the rotating shaft and bearing ring are prone to axial movement, which not only significantly increases frictional loss between components and reduces transmission efficiency, but may also cause equipment vibration, affect operational stability, and even cause equipment failure.

[0005] In response to the aforementioned technologies, the inventors propose a high-strength bearing support to solve the problems described above. Utility Model Content

[0014] Optionally, the outer surface of the cover plate is symmetrically bolted with positioning bolts, and the end threads of the positioning bolts penetrate the sleeve. A chuck is provided between the bearing ring and the corresponding cover plate.

[0015] By adopting the above technical solution, the positioning bolts achieve a rigid connection between the cover plate and the sleeve, and the chuck restricts the outer displacement of the bearing ring. The dual action prevents the bearing ring from shifting and ensures transmission accuracy.

[0016] Optionally, a gasket is provided between the positioning bolt and the corresponding cover plate.

[0017] By adopting the above technical solution, the gasket fills the gap between the positioning bolt and the cover plate, disperses the bolt tightening force to avoid deformation of the cover plate, and at the same time enhances the sealing performance to prevent impurities from entering the sleeve.

[0019] By adopting the above technical solution, the outer ring and the inner ring are strengthened to form a dual-strength structure, which improves the deformation resistance of the cover plate and ensures the long-term stress stability of the cover plate.

[0020] Optionally, the two sides of the rotating shaft are symmetrically fixed with connecting ends, the outer surface of the connecting ends is provided with spline grooves, and spline blocks are locked in the spline grooves.

[0021] By adopting the above technical solution, the connecting end facilitates the docking of the rotating shaft with external components, and the spline groove and spline block mesh to achieve backlash-free torque transmission, avoiding slippage and energy loss.

[0022] Optionally, the outer surface of the sleeve is symmetrically provided with planar grooves on the upper side, and the upper surface of the planar grooves is bolted to a reinforcing bolt.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.

[0031] Example

[0032] A high-strength bearing support, as described in the reference Figure 1-3The device includes a sleeve 1 and a mounting plate 3. The upper surface of the mounting plate 3 has symmetrically formed mounting grooves 31. First, the entire support assembly is bolted to the designated installation position on the external equipment using the mounting grooves 31. The symmetrical design of the mounting grooves 31 ensures balanced force during installation, preventing additional stress on the support due to installation misalignment. A rotating shaft 2 is located inside the sleeve 1, and a bearing ring 12 is symmetrically rotated inside the sleeve 1. The rotating shaft 2 is fitted inside the bearing ring 12. Cover plates 4 are symmetrically arranged on both sides of the sleeve 1, and a mounting plate is symmetrically fixed to the lower surface of the sleeve 1. 3. The symmetrically fixed limiting rings 11 inside the sleeve 1 form an axial constraint space. The rotating shaft 2 is locked between the two limiting rings 11, and the axial movement of the rotating shaft 2 is directly restricted by the limiting rings 11. At the same time, the symmetrically rotatable bearing rings 12 inside the sleeve 1 provide radial support for the rotating shaft 2. The rotating shaft 2 is sleeved in the bearing ring 12, so that the rotating shaft 2 can achieve low friction rotation by relying on the rotation of the bearing ring 12. The bearing ring 12 is located between the corresponding limiting ring 11 and the cover plate 4. The limiting ring 11 further positions the inner side of the bearing ring 12.

[0033] A chuck 13 is provided between the bearing ring 12 and the corresponding cover plate 4. A positioning bolt 41 is symmetrically bolted to the outer surface of the cover plate 4, and the end thread of the positioning bolt 41 passes through the sleeve 1. A gasket 42 is provided between the positioning bolt 41 and the corresponding cover plate 4. The chuck 13 restricts the axial displacement of the outer side of the bearing ring 12 by fitting and contacting the bearing ring 12 and the cover plate 4, so as to prevent the bearing ring 12 from shifting during rotation. Subsequently, the cover plate 4 is fixed to both sides of the sleeve 1 by the positioning bolt 41 symmetrically bolted to the outer surface of the cover plate 4. The end thread of the positioning bolt 41 passes through the sleeve 1, realizing the rigid connection between the cover plate 4 and the sleeve 1. The gasket 42 provided between the positioning bolt 41 and the corresponding cover plate 4 can fill the small gap between the two, which not only improves the connection sealing (prevents dust and impurities from entering the inside of the sleeve 1 and affecting the rotation of the bearing ring 12), but also disperses the clamping force of the positioning bolt 41, so as to prevent the cover plate 4 from being deformed by local stress.

[0034] A limiting ring 11 is symmetrically fixed inside the sleeve 1. The rotating shaft 2 is locked between the two limiting rings 11. The bearing ring 12 is located between the corresponding limiting ring 11 and the cover plate 4. A reinforcing outer ring 43 is fixed on the outer side of the cover plate 4, and a reinforcing inner ring 44 is fixed on the inner side of the cover plate 4. The reinforcing outer ring 43 fixed on the outer side of the cover plate 4 and the reinforcing inner ring 44 fixed on the inner side form a "double reinforcing structure", which can effectively improve the deformation resistance of the cover plate 4. When the positioning bolt 41 is tightened or the force inside the sleeve 1 is transmitted to the cover plate 4, the reinforcing outer ring 43 and the reinforcing inner ring 44 can disperse the stress and prevent the cover plate 4 from warping or breaking due to uneven force.

[0035] The rotating shaft 2 is symmetrically fixed with connecting ends 21 on both sides. The outer surface of the connecting ends 21 is provided with spline grooves 23, and spline blocks 22 are locked in the spline grooves 23. The connecting ends 21 symmetrically fixed on both sides of the rotating shaft 2 are used to connect with external transmission components (such as motor shafts and load shafts). The spline blocks 22 are locked in the spline grooves 23 on the outer surface of the connecting ends 21. Through the meshing of the spline blocks 22 and the spline grooves 23, the rotating shaft 2 is rigidly connected to the external components, ensuring that there is no slippage during torque transmission. The symmetrical design of the connecting ends 21 makes the force on both ends of the rotating shaft 2 balanced, avoiding shaft bending caused by unilateral force.

[0036] A planar groove 14 is symmetrically formed on the upper side of the outer surface of the sleeve 1. A reinforcing bolt 15 is bolted to the upper surface of the planar groove 14. A positioning groove 16 is formed on the upper inner side of the cover plate 4 to cooperate with the reinforcing bolt 15. The reinforcing bolt 15 is screwed into the positioning groove 16, which can further strengthen the connection between the cover plate 4 and the sleeve 1 on the basis of the positioning bolt 41, forming a "double bolt fixing" structure to prevent the cover plate 4 from loosening under long-term vibration or high load conditions, and ultimately ensure the structural stability of the entire support.

[0037] The implementation principle of this application embodiment is as follows: First, the entire support base device is bolted to the designated installation position of the external equipment through the symmetrically opened installation grooves 31 on the upper surface of the mounting plate 3. The symmetrical design of the installation grooves 31 ensures that the force is balanced during installation and avoids additional stress on the support base due to installation offset.

[0038] The symmetrically fixed limiting rings 11 inside the sleeve 1 form an axial constraint space. The rotating shaft 2 is locked between the two limiting rings 11, and the axial movement of the rotating shaft 2 is directly restricted by the limiting rings 11. At the same time, the symmetrically rotatable bearing rings 12 inside the sleeve 1 provide radial support for the rotating shaft 2. The rotating shaft 2 is sleeved in the bearing ring 12, so that the rotating shaft 2 can achieve low friction rotation by relying on the rotation of the bearing ring 12. The bearing ring 12 is located between the corresponding limiting ring 11 and the cover plate 4. The limiting ring 11 further positions the inner side of the bearing ring 12.

[0039] A chuck 13 is provided between the bearing ring 12 and the corresponding cover plate 4. The chuck 13 restricts the axial displacement of the bearing ring 12 on the outside by fitting and contacting the bearing ring 12 and the cover plate 4, so as to prevent the bearing ring 12 from shifting during rotation. Then, the cover plate 4 is fixed to both sides of the sleeve 1 by the positioning bolts 41 that are symmetrically bolted to the outer surface of the cover plate 4. The end thread of the positioning bolt 41 penetrates the sleeve 1, realizing the rigid connection between the cover plate 4 and the sleeve 1. The gasket 42 provided between the positioning bolt 41 and the corresponding cover plate 4 can fill the small gap between them, which can improve the connection sealing (prevent dust and impurities from entering the sleeve 1 and affecting the rotation of the bearing ring 12) and disperse the clamping force of the positioning bolt 41, so as to prevent the cover plate 4 from being deformed by local stress.

[0040] The outer reinforcing ring 43 fixed on the outer side of the cover plate 4 and the inner reinforcing ring 44 fixed on the inner side form a "double reinforcing structure", which can effectively improve the deformation resistance of the cover plate 4. When the positioning bolt 41 is tightened or the force inside the sleeve 1 is transmitted to the cover plate 4, the outer reinforcing ring 43 and the inner reinforcing ring 44 can disperse the stress and prevent the cover plate 4 from warping or breaking due to uneven force.

[0041] The two sides of the rotating shaft 2 are symmetrically fixed with connecting ends 21 for docking with external transmission components (such as motor shafts and load shafts). The spline groove 23 on the outer surface of the connecting end 21 is fitted with a spline block 22. Through the meshing of the spline block 22 and the spline groove 23, the rotating shaft 2 is rigidly connected to the external component, ensuring that there is no slippage during torque transmission. The symmetrical design of the connecting ends 21 makes the force on both ends of the rotating shaft 2 even, avoiding shaft bending caused by unilateral force.

[0042] A planar groove 14 is symmetrically provided on the upper side of the outer surface of the sleeve 1. A reinforcing bolt 15 is bolted to the upper surface of the planar groove 14. A positioning groove 16 is provided on the upper inner side of the cover plate 4 to cooperate with the reinforcing bolt 15. After the reinforcing bolt 15 is screwed into the positioning groove 16, the connection between the cover plate 4 and the sleeve 1 can be further strengthened on the basis of the positioning bolt 41, forming a "double bolt fixing" structure to prevent the cover plate 4 from loosening under long-term vibration or high load conditions, and ultimately ensure the structural stability of the entire support.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
