Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically to a double-headed bearing device. Background Technology

[0002] In many mechanical devices, such as automobiles, industrial machine tools, and wind turbines, bearings are often required to support rotating shafts and reduce friction. Traditional single-ended bearings can only provide support at one end, while in some applications, support needs to be provided at both ends of the shaft to ensure its stability and load-bearing capacity. Existing solutions typically use two independent single-ended bearings mounted at each end of the shaft, but this increases assembly complexity and cost, and may affect the overall structural compactness.

[0003] Therefore, designing a double-headed bearing device that can provide support at both ends of the shaft simultaneously has significant application value. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a double-headed bearing device.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a double-headed bearing device, including a central shaft, a left bearing, a right bearing, and a fastening connector;

[0006] Both the left and right bearings have an extension rod fixedly installed at one end that can extend to the inner wall of the central shaft. After the extension rod of the left or right bearing extends into the central shaft, it is detachably connected to the central shaft through a fastening connector.

[0007] The fastening connector includes a first arc-shaped plate and a second arc-shaped plate that are hinged together. After the extension rod extends into the central shaft, the first arc-shaped plate is placed close to the central shaft and the bearing by a limiting mechanism. The second arc-shaped plate is connected to the first arc-shaped plate by a fastening mechanism.

[0008] As an improvement, the limiting mechanism includes a limiting plate, an annular protrusion, and an annular plate;

[0009] Limiting plates are provided at both ends of the inner walls of the first and second arc-shaped plates. Annular protrusions are fixedly provided on the outer walls of both ends of the central shaft. Annular plates are provided on each extension rod. After the extension rod of the left or right bearing extends into the central shaft, it pushes the two limiting plates on the inner wall of the first arc-shaped plate to tightly adhere to the annular plate and the annular protrusion, respectively.

[0010] As an improvement, the fastening mechanism includes a fastening connecting plate;

[0011] Both the first and second arc-shaped plates are equipped with fastening connecting plates at their other ends. After the first and second arc-shaped plates rotate and move closer to each other, the two fastening connecting plates are pressed tightly together. Bolts pass through the pre-set through holes on the two fastening connecting plates and are fastened by nuts.

[0012] As an improvement, a rubber sealing ring is also included. The rubber sealing ring is placed on the outer wall of the annular protrusion and the annular plate. After the fastening connector is snapped into the annular protrusion and the annular plate, the inner wall of each limiting plate is tightly attached to the rubber sealing ring.

[0013] As an improvement, a locking through-hole is also included;

[0014] Each annular protrusion, annular plate, and limiting plate is provided with a locking through hole, and multiple locking through holes are evenly distributed. After the fastening connector connects the central shaft and the left or right bearing, the screw passes through the locking through hole and is fastened by the nut.

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] 1. Precise design ensures concentricity at both ends of the central shaft, improving the overall system stability and operating efficiency;

[0017] 2. The use of detachable fasteners allows for quick replacement or repair of bearings on either side without completely disassembling the entire device;

[0018] 3. The combination of rubber sealing rings and locking through holes effectively prevents harmful substances such as dust and moisture from entering the bearing, thus extending its service life. Attached Figure Description
