Description

Technical Field

[0001] The utility model relates to the technical field of gearboxes, in particular to a gearbox output shaft gear. Background Art

[0002] In existing traditional transmission output shaft drive systems, simple gears or couplings are typically used to achieve power transmission. Traditional transmission structures often rely on a direct connection between a sleeve and fixing bolts to ensure the linkage between the output shaft and the main shaft. However, during high-intensity operation, this structure often suffers from loosening and wear of the transmission structure, leading to a decrease in transmission efficiency. Furthermore, due to the tight fit between transmission components, traditional structures struggle to effectively manage heat dissipation. Prolonged operation can easily lead to localized overheating, which in turn accelerates component aging and wear, impacting the overall service life of the transmission.

[0003] The main defects of traditional solutions include:

[0004] Poor heat dissipation: Due to the lack of dedicated heat dissipation design, traditional transmission systems are prone to heat accumulation under high loads or prolonged operation, causing the temperature of components such as bearings and gears to rise. Excessive temperatures can lead to degraded material properties, aging and deformation of components, and affect the stability and service life of the equipment.

[0005] Unstable structure: Traditional transmission systems typically use simple bolt or ferrule connections. After long-term operation, loose bolts or wear between shafts are common, which can easily lead to reduced transmission efficiency or system failure. The lack of effective stabilization devices reduces the reliability of the transmission system under high loads, affecting the long-term stable operation of the equipment.

[0006] In response to the above-mentioned defects, the present invention solves the problems of insufficient heat dissipation and unstable structure in the traditional gearbox output shaft transmission system by optimizing the transmission structure and adding heat dissipation design, thereby improving transmission efficiency and reliability. Utility Model Content

[0007] This utility model provides an output shaft gear structure for a transmission, aiming to improve transmission efficiency, heat dissipation, and structural stability. The structure comprises an output shaft, a main shaft, an outer gear plate, and centrifugal fan discs fixed to either side of the outer gear plate. Through rational transmission and heat dissipation design, the output shaft's reliability and durability are ensured under high-intensity operation. The details are as follows:

[0008] A transmission output shaft gear comprises an output shaft, a main shaft, an outer gear disc, and a centrifugal fan disc fixed to either side of the outer gear disc. The output shaft and main shaft are respectively provided with a first disc and a second disc at their ends. Both the main shaft and the output shaft have a core hole on their inner sides. A transfer rod is removably sleeved inside the core hole, and the other end of the transfer rod is inserted into the inner side of the core hole of the output shaft. The surfaces of the first and second discs are each provided with a plurality of through holes and threaded tie rods. The inner side of the outer gear disc is provided with a fixed screw sleeve that mates with the threaded tie rods. The inner side of the centrifugal fan disc is provided with a positioning flap that engages with the surfaces of the first and second discs. The inner side of the centrifugal fan disc is provided with a plurality of air outlet swirl holes. The surface of the centrifugal fan disc is provided with heat dissipation ribs. The mutual cooperation between the output shaft and the main shaft ensures a stable connection of the output shaft, and the detachable design facilitates maintenance and replacement. Furthermore, the threaded tie rod design ensures structural stability, effectively prevents loosening due to vibration, and improves transmission efficiency.

[0009] In a preferred embodiment, the present invention can be further configured such that the outer gear disc has an annular gear structure and transmission teeth are formed on its surface. By providing the outer gear disc with an annular gear structure, the contact area of ​​the gear transmission is increased, the transmission is made smoother, friction and wear are reduced, and transmission efficiency is effectively improved.

[0010] In a preferred embodiment, the present invention can be further configured such that the output shaft, main shaft, and transmission rod are located on the same axis, and the first shaft disc, threaded tie rod, and centrifugal fan disc are symmetrically arranged on either side of the outer gear disc. This symmetrical arrangement ensures a more balanced structure during operation, reduces vibration caused by eccentric loads, and effectively improves the stability and service life of the device during high-speed operation.

[0011] In a preferred embodiment, the present invention can be further configured such that the air outlet vortex hole is arc-shaped and radially penetrates the centrifugal fan disc. The arc-shaped air outlet vortex hole design facilitates airflow diversion, enhances heat dissipation, prevents component aging due to high temperatures, and improves the operating efficiency and reliability of the equipment.

[0012] In a preferred embodiment, the present invention can be further configured such that the heat dissipation ribs are protruding strips and located on the side of the centrifugal fan disc facing away from the outer gear disc. This structure, by providing heat dissipation ribs on the surface of the centrifugal fan disc, increases the surface area of ​​the air flow path, further improving heat dissipation and preventing component deformation due to high temperatures.

[0013] In a preferred embodiment, the present invention can be further configured such that the threaded tie rod passes through the output shaft, the fixed screw sleeve, and the second shaft disc to connect the output shaft to the main shaft. The through-threaded tie rod design ensures a secure connection between the output shaft and the main shaft, preventing loosening during operation and further improving the structural stability and safety of the device.

[0014] The beneficial effects achieved by the utility model are:

[0015] 1. In the present invention, by arranging air outlet swirl holes and heat dissipation gaps on the centrifugal fan disc, it can effectively promote air flow, take away heat, improve heat dissipation effect, prevent aging and deformation of parts caused by overheating, thereby extending the service life of the gearbox and improving the overall reliability of the equipment.

[0016] 2. In this utility model, by providing an external gear disc and a centrifugal fan disc between the output shaft and the main shaft, a reliable transmission connection is achieved, effectively improving the transmission efficiency and stability of the gearbox output shaft. Furthermore, the fixed screw sleeve on the external gear disc cooperates with the threaded tie rod to ensure structural stability and reduce mechanical wear caused by looseness.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0024] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0025] The following is combined with Figure 1-Figure 4 Some embodiments of the present invention provide a transmission output shaft gear. Example 1

[0026] The utility model relates to a gearbox output shaft gear structure, which mainly includes an output shaft 100, a main shaft 200, an outer gear disc 300, and a centrifugal fan disc 400 fixed on both sides of the outer gear disc 300. Specifically, the output shaft 100 is the output shaft, the main shaft 200 is the main shaft, and the ends of the output shaft 100 and the main shaft 200 are respectively provided with a first shaft disc 110 and a second shaft disc 210. During the installation process of the structure, the inner sides of the output shaft 100 and the main shaft 200 are provided with a core shaft hole 220, and the inner side of the core shaft hole 220 is detachably sleeved with a conduction rod 230, and the other end of the conduction rod 230 is inserted into the inner side of the core shaft hole 220 of the output shaft 100 to achieve a tight connection between the two shafts. At the same time, a number of through holes are opened on the surface of the first shaft disc 110 and the second shaft disc 210, and are equipped with threaded pull rods 120 for fastening.

[0027] On this basis, the outer gear disc 300 is an annular structure, installed between the output shaft 100 and the main shaft 200, and has transmission teeth for transmitting torque. A fixed screw sleeve 310 is provided on the inner side of the outer gear disc 300, which is compatible with the threaded pull rod 120 to ensure that the outer gear disc 300 does not slip axially during operation. The centrifugal fan disc 400 is located on both sides of the outer gear disc 300. Its inner side is engaged with the surfaces of the first and second shaft discs 110 and 210 through positioning flaps 420 to further enhance the stability of the structure.

[0028] Furthermore, the centrifugal fan disc 400 is evenly distributed with a number of air outlet swirl holes 410 on its inner side. These air outlet swirl holes 410 are arc-shaped and radially extend through the centrifugal fan disc 400, forming a structure that effectively promotes air flow and enhances heat dissipation. The centrifugal fan disc 400 also features heat dissipation ribs 401 on its surface. These protruding ribs are located on the side away from the outer gear disc 300, further enhancing the cooling effect and providing better heat dissipation performance under high-temperature conditions.

[0029] Working effect: Through the above structural configuration, this embodiment enhances the heat dissipation effect of the gearbox output shaft while maintaining transmission stability, avoids aging and deformation of parts caused by high temperature, and improves overall reliability. Example 2

[0030] In this embodiment, the utility model further optimizes the transmission shaft and heat dissipation structure. In addition to the structure described in Example 1, a number of guide grooves are provided on the outside of the outer toothed disc 300 in this embodiment to further improve air flow. The outer toothed disc 300 is an annular tooth structure with transmission teeth on the surface to increase the transmission area and transmission efficiency. In this embodiment, the output shaft 100, the main shaft 200 and the conduction rod 230 are designed to be located on the same axis, so that the operation of the entire device is smoother. The first shaft disc 110, the threaded pull rod 120 and the centrifugal fan disc 400 are symmetrically arranged on both sides of the outer toothed disc 300, which further enhances the symmetry of the device and reduces unnecessary vibrations.

[0031] In this embodiment, the air outlet vortex hole 410 adopts a special optimized curvature design, making it more suitable for guiding and discharging airflow, forming a vortex effect, and further accelerating the cooling process. At the same time, the number and distribution density of the heat dissipation ribs 401 in this embodiment have been increased, resulting in a larger cooling area and more significant heat dissipation effect.

[0032] Working Effect: By optimizing the design of the air outlet vortex hole 410, this embodiment can achieve more efficient air flow and enhance heat dissipation performance. In addition, the symmetrical structural layout greatly reduces vibration during operation, further improving the durability and operating stability of the device.
