Description

Technical Field

[0001] This utility model belongs to the field of bearing housing technology and relates to a bearing housing structure. Background Technology

[0002] Bearing housings are critical components in mechanical systems used to support and secure bearings. They typically work in conjunction with the bearings to transfer the bearing load to the equipment frame, while also providing mounting, positioning, and sealing functions for the bearings. Widely used in various types of rotating machinery, they are essential foundational components ensuring stable equipment operation; the bearing housing structure is one type of bearing housing.

[0003] The existing bearing housings are fixed and the installation height cannot be adjusted. If the installation surface height of the equipment foundation or frame does not match the fixed height of the bearing housing, it is necessary to compensate by on-site processing, such as milling the base, adding shims, or adjusting the anchor bolts, which greatly increases the installation time and labor costs. At the same time, when the bearing or bearing housing needs to be replaced, the fixed height may restrict the installation of the new parts, requiring the equipment frame or base to be readjusted, and even leading to the simultaneous replacement of related parts, increasing maintenance costs. Utility Model Content

A drive screw is symmetrically arranged on the mounting bracket, and both ends of the drive screw are rotatably connected to the mounting bracket. A handwheel is mounted on the top of the drive screw, and a drive block is threadedly connected to the drive screw. Two drive blocks are connected to the same connecting plate. Connecting holes are symmetrically arranged on the connecting plate. A bearing housing bottom support shell is connected to the connecting plate, and connecting bolts are symmetrically installed on the bearing housing bottom support shell. The bearing housing bottom support shell is mounted on the connecting plate via the connecting bolts.

[0006] An upper support shell is connected to the bottom support shell of the bearing housing. The upper support shell is symmetrically provided with mounting bolts. The bottom of the mounting bolts is threaded to the bottom support shell of the bearing housing, and the upper support shell is installed on the bottom support shell of the bearing housing by the mounting bolts.

[0007] A heat-conducting ring is provided on the bottom support shell of the bearing seat, and an inner bushing is fixedly connected to the inner wall of the heat-conducting ring. Multiple heat dissipation fins are installed on the heat-conducting ring.

[0008] The bearing housing bottom support shell is symmetrically provided with positioning grooves, and the lower end of the upper support shell is symmetrically provided with positioning rods. The positioning rods are inserted into the positioning grooves to facilitate the installation of the bearing housing bottom support shell and the upper support shell.

[0009] The mounting bracket is U-shaped and has multiple mounting holes for fixing the mounting bracket.

[0010] Rubber pads are symmetrically arranged at the bottom of the mounting bracket, and hooks are installed on the upper support shell.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by driving the symmetrical screw with a handwheel, the connecting plate and the bottom support shell are raised and lowered synchronously, realizing the adjustment of the installation height of the bearing seat, adapting to the foundation height of different equipment, solving the problem of on-site processing or adding shims when installing fixed bearing seats, significantly improving installation efficiency, replacing the complicated operation of on-site processing of the base, adding shims or adjusting the anchor bolts of fixed bearing seats, greatly reducing installation time and labor costs, and is especially suitable for scenarios where multiple equipment are compatible or the on-site foundation is uneven.

[0015] Example 1 like Figures 1-4As shown, a bearing housing structure includes a mounting bracket 1. A drive screw 2 is symmetrically arranged on the mounting bracket 1, with both ends of the drive screw 2 rotatably connected to the mounting bracket 1. A handwheel 3 is mounted on the top of the drive screw 2. A drive block 4 is threadedly connected to the drive screw 2. Two drive blocks 4 are connected to the same connecting plate 5. Connecting holes 51 are symmetrically arranged on the connecting plate 5. A bearing housing bottom support shell 7 is connected to the connecting plate 5. Connecting bolts 6 are symmetrically installed on the bearing housing bottom support shell 7. The bearing housing bottom support shell 7 is mounted on the connecting plate 5 via the connecting bolts 6.

[0016] The drive screws 2 and handwheels 3 symmetrically arranged on the mounting bracket 1 constitute a manual lifting device. When the handwheel 3 is rotated, the drive screws 2 rotate around their own axis, driving the two drive blocks 4 to move up and down synchronously through threaded transmission. The drive blocks 4 are connected by a connecting plate 5 to ensure the synchronous movement of the drive blocks 4 on both sides. The connecting holes 51 on the connecting plate 5 are fixed to the bottom support shell 7 of the bearing seat by connecting bolts 6 to achieve height adjustment. Rotating the handwheel 3 clockwise raises the drive blocks 4, driving the connecting plate 5 and the bottom support shell 7 of the bearing seat to rise. Rotating the handwheel 3 counterclockwise lowers the drive blocks 4, reducing the height of the bottom support shell 7 of the bearing seat. Stepless height adjustment is achieved through mechanical transmission, adapting to different equipment foundation heights and solving the problem of needing on-site processing or adding shims when installing fixed bearing seats, significantly improving installation efficiency.

[0017] An upper support shell 8 is connected to the bottom support shell 7 of the bearing housing. Mounting bolts 9 are symmetrically arranged on the upper support shell 8. The bottom of the mounting bolts 9 is threaded onto the bottom support shell 7 of the bearing housing, and the upper support shell 8 is mounted on the bottom support shell 7 of the bearing housing via the mounting bolts 9. A heat-conducting ring 13 is provided on the bottom support shell 7 of the bearing housing. An inner bushing 12 is fixedly connected to the inner wall of the heat-conducting ring 13. Multiple heat dissipation fins 14 are installed on the heat-conducting ring 13. Positioning grooves 10 are symmetrically opened on the bottom support shell 7 of the bearing housing. Positioning rods 11 are symmetrically installed at the lower end of the upper support shell 8. The positioning rods 11 are inserted into the positioning grooves 10 to facilitate the installation of the bottom support shell 7 and the upper support shell 8 of the bearing housing.

[0018] The height adjustment structure can be removed during use. This bearing housing can be used independently, and can be assembled arbitrarily according to the user's usage. During operation, the bearing housing consists of a bottom support shell 7 and an upper support shell 8, connected by mounting bolts 9 for easy step-by-step installation. The bottom support shell 7 is fixed to the connecting plate 5 by mounting bolts 9. The positioning rod 11 is inserted into the positioning groove 10 of the bottom support shell to achieve quick alignment, ensuring that the axes of the upper and lower shells coincide and avoiding installation deviations. The insertion design of the positioning rod 11 and the positioning groove 10 simplifies the alignment process. After the mounting bolts 9 are tightened, a closed support structure is formed to ensure stable clamping of the bearing outer ring. The inner bushing 12 directly contacts the bearing outer ring and uses a high thermal conductivity material such as copper alloy to quickly absorb the heat generated by the bearing operation. The heat-conducting ring 13 is fixedly connected to the outer wall of the inner bushing 12 to conduct heat to the outside. The heat dissipation fins 14 are evenly distributed on the outer wall of the heat-conducting ring 13, which accelerates the convection and radiation of heat into the air by increasing the surface area. The inner bushing 12 indirectly reduces the bearing operating temperature and extends its service life.

[0019] The mounting bracket 1 is U-shaped and has multiple mounting holes 15 for fixing the mounting bracket 1. Rubber pads 16 are symmetrically arranged at the bottom of the mounting bracket 1. The mounting bracket 1 is fixed in the multiple mounting holes 15 by external bolts. The rubber pads 16 buffer vibration and reduce noise. Hooks 17 are installed on the upper support shell 8. The hooks 17 of the upper support shell 8 can be used to hang lubrication pipes or cables to optimize the equipment layout, and can also be used to hang the bearing seat.
