Description

A high-efficiency heat dissipation universal joint housing structure Technical Field

[0001] This utility model relates to the field of universal joint technology, specifically to a high-efficiency heat dissipation universal joint shell structure. Background Technology

[0002] Universal joints, as crucial components in mechanical transmissions, are widely used in various mechanical equipment, especially in applications requiring the transmission of torque and angular changes. Traditional universal joint housing structures often prioritize mechanical strength and durability in their design and manufacturing, neglecting the importance of heat dissipation.

[0003] However, as modern machinery develops towards higher speeds and higher power densities, the heat generated by universal joints during operation gradually increases. If heat cannot be effectively dissipated, the temperature will rise, thus affecting the performance and lifespan of the universal joint. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a high-efficiency heat dissipation universal joint housing structure, solving the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency heat-dissipating universal joint housing structure, comprising a cross shaft, outer rings, shaft connectors, and bearing seats. The four outer rings are fixedly connected to the four corners of the cross shaft. The shaft connectors are fixedly mounted on the top of the outer rings. The bearing seats are installed and connected to the shaft connectors. The bearing seats have two bolt holes with outward openings on both sides, and the bolt holes on both sides are symmetrically positioned. The cross shaft has mounting holes with outward openings on both the upper and lower sides, and the mounting holes on both sides are symmetrically positioned.

[0008] Preferably, the inner wall of the mounting hole is provided with four outward-facing heat dissipation grooves, and the heat dissipation grooves are arranged in a circular array.

[0009] Preferably, a cross-shaped heat exchange plate is installed in the mounting hole on one side, and the heat exchange plate has an outward-facing mounting groove at its center.

[0013] (III) Beneficial Effects

[0014] This invention provides a high-efficiency heat dissipation universal joint housing structure. It has the following beneficial effects:

[0015] 1. This solution significantly improves the heat dissipation capacity of the universal joint by integrating heat dissipation grooves, heat exchange plates, and heat dissipation holes into the design. Heat can be quickly conducted from the cross shaft to the heat exchange plate and effectively dissipated into the surrounding environment through the heat dissipation holes, thereby reducing the operating temperature of the universal joint and extending its service life.

Detailed Implementation

[0022] This utility model embodiment provides a high-efficiency heat dissipation universal joint housing structure, as shown in Figures 1-4, including a cross shaft 101, an outer ring 102, a shaft connector 103, and a bearing seat 107. The four outer rings 102 are fixedly connected to the four corners of the cross shaft 101. The shaft connector 103 is fixedly installed on the top of the outer ring 102. The bearing seat 107 is installed and connected to the shaft connector 103. The bearing seat 107 has two bolt holes 104 with outward openings on both sides, and the bolt holes 104 on both sides are symmetrically arranged. The cross shaft 101 has mounting holes 106 with outward openings on both the upper and lower sides, and the mounting holes 106 on both sides are symmetrically arranged.

[0023] Furthermore, the inner wall of the mounting hole 106 has four outward-facing heat dissipation slots 108, which are arranged in a ring array.

[0024] Furthermore, a cross-shaped heat exchange plate 111 is installed in the mounting hole 106 on one side, and the heat exchange plate 111 has an outward-facing mounting groove 113 at its center.

[0025] Furthermore, the heat exchange plate 111 is installed into the mounting hole 106 and the heat dissipation grooves 108 on each side, and a removable mounting screw 109 is installed at the contact position between the mounting groove 113 and the mounting hole 106.

[0026] It should be further noted that the heat exchange plate 111 can be stably connected to the mounting hole 106 by mounting screws 109.

[0027] Furthermore, vertically installed heat dissipation connecting plates 105 are mounted at the four front corners of the heat exchange plate 111, and the heat dissipation connecting plates 105 abut against the side of the cross shaft 101.

[0028] Furthermore, the heat exchange plate 111 is provided with a number of outward-facing heat dissipation holes 112, and the heat dissipation holes 112 on each side are arranged in an array.

[0029] It should be further noted that the heat dissipation connector 105 is made of heat exchange material.

[0030] When using this solution, the cross shaft 101 is moved as a whole to the working position of aviation or engineering machinery, and connected through the bearing seats 107 on all four sides, and the fixed connection is easily made through the bolt holes 104 on both sides.

[0031] Subsequently, based on the working environment of the universal joint, heat exchange plates 111 are selectively installed in the mounting holes 106 on both sides of the cross shaft 101. During the installation process, the center mounting groove 113 of the heat exchange plate 111 is first aligned with the mounting hole 106 and slowly pushed in to ensure that the heat exchange plate 111 can be smoothly inserted into the mounting hole 106 and the heat dissipation grooves 108 on each side. Then, the heat exchange plate 111 is firmly installed in the abutment position of the mounting hole 106 by the detachable mounting screws 109 to achieve the fixing effect, which further enhances the heat conduction effect between the heat exchange plate 111 and the cross shaft 101.

[0032] It is worth noting that the heat dissipation connecting plates 105 at the four corners of the heat exchange plate 111 are vertically erected and tightly abut against the sides of the cross shaft 101. These heat dissipation connecting plates 105 are made of heat exchange material with high thermal conductivity, which can quickly conduct the heat generated by the cross shaft 101 to the heat exchange plate 111. At the same time, the heat dissipation connecting plates 105 also increase the heat exchange area, further improving the heat dissipation efficiency.

[0033] At this time, the heat exchange plate 111 is provided with a number of outward-facing heat dissipation holes 112. The heat dissipation holes 112 are arranged in an array on each side of the heat exchange plate 111. The design of the heat dissipation holes 112 helps air circulation and further accelerates the dissipation of heat. When the universal joint is working, the heat generated is conducted to the heat exchange plate 111 through the cross shaft 101, and then quickly dissipated to the surrounding environment through the heat dissipation holes 112, thereby achieving efficient heat dissipation.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
