Description

Technical Field

[0001] The utility model relates to the technical field of center shaft connectors, in particular to a casting center shaft connector with a heat sink. Background Art

[0002] The shaft is a shaft that connects two rotating parts. Its function is to bear the load of the rotating parts and transmit power. The material of the shaft is usually metal materials such as steel, copper, aluminum or alloy. The shape and size of the shaft depends on how it is used in different mechanical equipment. The shaft is mainly used to transmit or convert motion and power. It is common in the transmission system of mechanical equipment. The shaft is widely used in various mechanical equipment, such as automobiles, trains, airplanes, ships, agricultural machinery, industrial production lines, etc.

[0003] A middle shaft connector is required when connecting the middle shaft. However, the existing middle shaft connector generally has a simple structure. The middle shaft will generate heat during the transmission process, and this heat will be conducted to the middle shaft connector. If this heat cannot be dissipated in time, long-term high temperature will cause metal fatigue of the middle shaft and the middle shaft connector, seriously affecting the service life of the middle shaft and the middle shaft connector. In this regard, we propose a casting middle shaft connector with a heat sink to solve the above-mentioned problems. Utility Model Content

[0004] The utility model aims to provide a casting mid-shaft connector with a heat sink to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a casting center shaft connector with a heat sink, comprising:

[0006] A central axis connector body, wherein both ends of the central axis connector body are provided with central axes, and both ends of the central axis connector body are provided with plug-in slots, and the two central axes are movably plugged into the two plug-in slots respectively, and the inner wall of the plug-in slot is provided with two grooves symmetrically arranged up and down, and arc-shaped heat conducting plates are arranged in the two grooves, and a plurality of heat conducting sheets are arranged on the inner wall of the arc-shaped heat conducting plate, and a plurality of heat conducting grooves adapted to the heat conducting sheets are arranged at the end of the central axis, and a plurality of evenly distributed through grooves are arranged on the inner wall of the groove, and heat dissipation fins are arranged in the through grooves, and the heat dissipation fins are arranged on the arc-shaped heat conducting plate.

[0007] Preferably, two pairs of fastening bolts are arranged on the main body of the central axis connector, and a pair of screw holes are opened at the end of the central axis, and the fastening bolts are threadedly connected in the screw holes.

[0008] Preferably, limiting blocks are fixedly welded on the inner walls of the two plug-in slots, and a limiting slot is provided at the end of the central axis, and the limiting slot is matched with the limiting block.

[0009] Preferably, the arc-shaped heat-conducting plate is fixedly bonded in the groove by glue, and the heat-dissipating fins are bonded to the arc-shaped heat-conducting plate by glue.

[0010] Preferably, the plurality of heat conducting sheets are integrally formed with the arc-shaped heat conducting plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model discloses that when using, the center axis connector body is fixedly connected with the center axis by the cooperation of the set fastening bolts and the screw holes. When the center axis generates heat due to rotation, the heat is transferred to the heat conducting sheet through the plug-in cooperation of the set multiple heat conducting sheets and the multiple heat conducting grooves. The heat conducting sheet then transfers the heat to the arc-shaped heat conducting plate. The arc-shaped heat conducting plate then transfers the heat to the multiple heat dissipating fins bonded thereto for heat dissipation. When the center axis rotates, the center axis connector body can be driven to rotate, thereby driving the multiple heat dissipating fins to rotate, so that the heat dissipating fins can dissipate heat faster, and the heat dissipation efficiency is improved, which solves the problem that long-term high temperature will cause metal fatigue of the center axis and the center axis connector, and seriously affect the service life of the center axis and the center axis connector.

[0021] Limiting blocks 12 are fixedly welded on the inner walls of the two plug-in slots 3, and a limiting slot 13 is provided at the end of the central axis 2. The limiting slot 13 is adapted to the limiting block 12. When the central axis connector body 1 is connected and installed with the central axis 2, the limiting block 12 is plugged in and matched with the limiting slot 13 to ensure that the central axis 2 can drive the central axis connector body 1 to rotate when it rotates.

When the central axis 2 generates heat due to rotation, the heat is transferred to the heat conducting sheet 6 through the plug-in cooperation of the set multiple heat conducting sheets 6 and the multiple heat conducting grooves 7. The heat conducting sheet 6 then transfers the heat to the arc-shaped heat conducting plate 5, and the arc-shaped heat conducting plate 5 then transfers the heat to the multiple heat dissipating fins 9 bonded thereto for heat dissipation. When the central axis 2 rotates, it can drive the central axis connector body 1 to rotate, thereby driving the multiple heat dissipating fins 9 to rotate, so that the heat dissipating fins 9 dissipate heat faster, improve the heat dissipation efficiency, and solve the problem that long-term high temperature will cause metal fatigue of the central axis and the central axis connector, seriously affecting the service life of the central axis and the central axis connector.
