Description

Technical Field

[0001] The utility model relates to a transmission gasket with a long service life, belonging to the field of transmission gaskets. Background Art

[0002] During the operation of the transmission, the gasket, as an important component, is subjected to various complex forces and vibrations. However, the design of transmission gaskets often fails to effectively cope with these challenges, resulting in gaskets being prone to wear and breakage after long-term use, thereby reducing the overall performance and stability of the transmission and shortening the service life of the gaskets.

[0003] Transmission gaskets are usually made of rigid materials and lack sufficient elasticity to absorb and compensate for the vibrations and shocks generated during the operation of the transmission. These vibrations and shocks will directly act on the gasket, causing stress concentration on the gasket surface, which will in turn cause cracks and wear. In addition, when the transmission runs at high speed, a large amount of heat will be generated between the gasket and adjacent components. Due to the limited thermal conductivity of traditional gasket materials and the lack of effective heat dissipation structure, this heat is difficult to dissipate quickly, causing the gasket temperature to rise, which in turn accelerates the aging and failure of the gasket material.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 A transmission gasket with a long service life comprises a bracket 1 and a sheath 2 slidably connected to the inner side of the bracket 1, and an inner bottom wall of the bracket 1 is provided with an elastic structure for elastic compensation.

[0025] like Figure 1 As shown, the elastic structure includes two shells 3 fixedly connected to the inner bottom wall of the bracket 1, an elastic telescopic rod 4 fixedly connected to the inner bottom wall of the shell 3, a connecting block 5 fixedly connected to the top end of the piston rod of the elastic telescopic rod 4, and an outer ring 6 fixedly connected between the upper surfaces of the two connecting blocks 5.

[0026] A heat dissipation component for dissipating heat is provided on the inner side of the outer ring 6 .

[0027] It should be noted that the upper surface and bottom of the bracket 1 are both provided with sliding openings adapted to the sheath 2, the top end of the sheath 2 is slidably connected to the inner side of the top sliding opening, and the bottom end of the sheath 2 is slidably connected to the inner side of the bottom sliding opening, the sheath 2 is fixedly connected to the inner side of the center of the outer ring 6, and the inner side of the sheath 2 is fixedly connected with an alloy inner ring 7.

[0028] The two shells 3 are respectively fixedly connected to the left side and the right side of the inner bottom wall of the bracket 1, and the right side wall of the left shell 3 and the left side wall of the right shell 3 are fixedly connected with a slider 8. The inner sides of the two sliders 8 are slidably connected with a slide rod 9. The upper and lower ends of the left slide rod 9 are bent to the right and fixedly connected to the left side wall of the sheath 2, and the upper and lower ends of the right slide rod 9 are bent to the left and fixedly connected to the right side wall of the sheath 2.

[0029] The heat dissipation assembly includes two installation cavities 10 opened on the inner side of the outer ring 6, a heat pipe 11 fixedly connected to the inner side of the installation cavity 10, and a heat dissipation gasket 12 in contact with one end of the heat pipe 11. The two installation cavities 10 are respectively opened on the left side and the right side of the inner part of the outer ring 6. The left side wall of the outer ring 6 is provided with an installation opening connected to the left installation cavity 10 and matched with the heat dissipation gasket 12. The right side wall of the outer ring 6 is provided with an installation opening connected to the right installation cavity 10 and matched with the heat dissipation gasket 12.

[0030] In addition, the right end of the left heat pipe 11 penetrates the inner right wall of the left installation cavity 10 and contacts the alloy inner ring 7, and the left end of the right heat pipe 11 penetrates the inner left wall of the right installation cavity 10 and contacts the alloy inner ring 7. The heat sink 12 is usually made of a material with good thermal conductivity, and may adopt a structure such as increasing the surface area or designing heat sink fins to increase the contact area with the surrounding environment, thereby improving the heat dissipation efficiency.

[0031] The working principle of the above embodiment is:

[0032] When the transmission is operating normally, the sleeve 2 and the alloy inner ring 7 inside it maintain close contact with the relevant parts of the transmission to ensure the stability of sealing and transmission. When the transmission vibrates or impacts, these forces first act on the alloy inner ring 7 and then are transmitted to the sleeve 2. Since the sleeve 2 is connected to the elastic telescopic rod 4 through the outer ring 6 and the connecting block 5, when it is vibrated or impacted, the sleeve 2 will move along the sliding direction of the bracket 1. At this time, the elastic telescopic rod 4 will expand and contract accordingly according to the force to provide necessary elastic compensation. At the same time, the slider 8 and the slide bar 9 limit the movement range of the sleeve 2 to ensure that it is elastically deformed within a certain range, thereby effectively absorbing and dispersing vibration and impact;

[0033] During the operation of the transmission, the alloy inner ring 7 will absorb and accumulate a large amount of heat due to its direct contact with relevant parts of the transmission. The heat is rapidly transferred to the heat pipe 11 through the contact surface between the alloy inner ring 7 and the heat pipe 11. The heat pipe 11 utilizes the phase change process of its internal working fluid to rapidly transfer the heat from one end of the alloy inner ring 7 to one end of the heat dissipation gasket 12, and the heat conducted by the heat pipe 11 is further dissipated to the external environment through the heat dissipation gasket 12.
