Description

Technical Field

[0001] This utility model relates to the field of gear shaft technology, specifically a bevel gear shaft. Background Technology

[0002] Traditional gear transmission equipment often employs simple heat dissipation structures, such as vents on the gear surface or heat sinks on the equipment casing, to reduce the heat generated during operation. However, these traditional methods rely on passive heat dissipation through natural airflow or the surface area of ​​the heat sinks, resulting in low heat dissipation efficiency. Especially under high load or high speed conditions, the heat accumulated inside the gears is difficult to dissipate quickly, easily leading to overheating. Furthermore, traditional gear equipment with relatively simple cooling structures often lacks cooling fluid guidance devices, resulting in uneven distribution of the cooling fluid and reduced heat dissipation effect.

[0003] The shortcomings of traditional heat dissipation designs are mainly reflected in the following aspects: First, the heat dissipation efficiency is low. Due to the lack of a dedicated airflow guiding structure or cooling channel, the heat dissipation process relies solely on passive natural air circulation, which is insufficient to meet the rapid heat dissipation requirements under high loads. Second, uneven distribution of the cooling fluid can easily cause localized overheating within the gears, leading to material aging, deformation, or even failure. Furthermore, traditional gear heat dissipation structures have poor sealing, making them susceptible to the intrusion of external dust and impurities, thus affecting the stability and service life of the equipment.

[0004] In view of this, we have studied and improved upon the existing problems to provide a bevel gear shaft, aiming to solve the current problems and improve the practical value through this technology. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art or related technologies.

[0006] This utility model relates to a bevel gear shaft, including a bevel gear, a main shaft, and a turbine disk fixed to the bottom surface of the bevel gear. This design aims to improve cooling effect and heat dissipation efficiency, thereby effectively extending the service life and operational stability of the equipment.

[0007] A bevel gear shaft includes: a bevel gear, a main shaft, and a turbine disk fixed to the bottom surface of the bevel gear. The inner side of the bevel gear has a bushing hole for fitting onto the surface of the main shaft. A flange is fixedly provided on the bottom surface of the bevel gear, and a flange cap is detachably installed on the bottom surface of the flange. The turbine disk is fixedly installed between the bevel gear and the flange cap. An inner cavity is formed on the inner side of the bevel gear, and a cooling guide plate is provided on the inner side of the inner cavity. An inlet groove is formed on the top surface of the bevel gear, and a flow channel hole communicating with the inlet groove and the inner cavity is formed inside the bevel gear. A plurality of evenly distributed swirl vanes are provided on the inner side of the turbine disk, and an exhaust hole located between adjacent swirl vanes is provided on the inner side of the turbine disk.

[0008] Working effect: Through this structural design, the inner cooling chamber of the bevel gear cooperates with the cooling guide plate of the flow guiding component, allowing the internal heat of the equipment to be quickly removed, preventing overheating. At the same time, the design of channels such as the inlet groove and flow channel holes improves the circulation efficiency of the cooling fluid, effectively ensuring the stability of gear operation.

[0009] In a preferred embodiment, the present invention can be further configured such that the bevel gear has a bevel gear structure, and each discharge hole is located in the gap between adjacent bevel gear teeth. Arranging discharge holes between the teeth of the bevel gear can effectively enhance the coverage of cooling fluid on the gear surface, improve heat dissipation, ensure that the cooling fluid is evenly distributed across the entire gear surface, and further reduce the risk of overheating.

[0010] In a preferred embodiment, the present invention can be further configured such that the discharge hole radially penetrates the outer wall of the bevel gear, and the other end of the discharge hole penetrates into the inner side of the inner cavity. Through the radially penetrating discharge hole, the cooling fluid can flow better between the gear and the inner cavity, increasing heat dissipation efficiency while maintaining the stability of the internal cooling system and preventing temperature fluctuations.

[0011] In a preferred embodiment, this invention can be further configured such that the flow channel holes are arranged obliquely, and the flow channel holes are arranged in a spiral shape with the spiral direction parallel to the oblique edge on the surface of the bevel gear. The spiral flow channel hole design, parallel to the oblique edge on the gear surface, makes the cooling fluid flow smoother, effectively improving the fluid guiding effect and further enhancing the cooling performance.

[0012] In a preferred embodiment, this invention can be further configured such that the cooling guide plate and the bevel gear are integrally formed, and the bevel gear is made of either ductile iron or alloy steel. The integrally formed cooling guide plate and bevel gear structure increases the strength and durability of the components, improves the thermal shock resistance of the equipment, and helps extend the service life of the equipment.

[0013] In a preferred embodiment, this invention can be further configured such that the exhaust port extends horizontally through both the inner and outer sides of the turbine disk, and the swirl vanes and exhaust port are arc-shaped strips. This design allows fluid to be discharged evenly on both the inner and outer sides of the turbine disk, avoiding fluid accumulation, ensuring smooth fluid discharge, and thus improving heat dissipation.

[0014] In a preferred embodiment, this invention can be further configured such that the surface of the flange cap is provided with a plurality of flange blades, and the flange blades have an airfoil cross-section. The airfoil flange blades provided on the surface of the flange cap can generate air convection during operation, further enhancing the cooling effect and effectively reducing the temperature of the gears during operation, thereby improving the heat dissipation capacity of the equipment.

[0015] The beneficial effects achieved by this utility model are as follows:

[0016] 1. In this utility model, by providing an inner cavity and a cooling guide plate on the inner side of the bevel gear, the equipment can dissipate heat quickly during operation, effectively reducing the risk of component aging caused by high temperature, and improving the service life and operational stability of the equipment.

[0017] 2. In this utility model, by setting several discharge holes on the outer wall of the bevel gear, the cooling fluid can flow smoothly along the flow channel holes, improving the cooling effect and maintaining stable internal pressure, further enhancing the safety of the equipment. The swirl vanes and exhaust holes are evenly distributed on the turbine disk, realizing the uniform distribution and discharge of the fluid, ensuring the heat dissipation performance of the equipment under high load conditions, and can utilize cooling oil or airflow for efficient heat dissipation.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0026] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0027] The following is in conjunction with the appendix Figures 1-5 This invention describes a bevel gear shaft provided by some embodiments of the present invention.

[0028] This embodiment provides a bevel gear shaft, including a bevel gear 100, a main shaft 200, and a turbine disk 300 fixed to the bottom surface of the bevel gear 100. In this embodiment, the inner side of the bevel gear 100 is provided with a bushing hole 101 for fitting onto the surface of the main shaft 200. A flange sleeve 102 is fixedly provided on the bottom surface of the bevel gear 100, and a flange cap 400 is detachably installed on the bottom surface of the flange sleeve 102. The turbine disk 300 is fixedly installed between the bevel gear 100 and the flange cap 400. In this structure, an inner cavity 140 is formed on the inner side of the bevel gear 100, and a cooling guide plate 141 is provided on the inner side of the inner cavity 140 for auxiliary cooling.

[0029] The top surface of the bevel gear 100 has an inlet groove 110, and the interior of the bevel gear 100 has a flow channel hole 130 that communicates with the inlet groove 110 and the interior of the inner cavity 140. This allows cooling fluid to enter through the inlet groove 110 and flow through the flow channel hole 130 to the inner cavity 140, achieving sufficient cooling. The inner side of the turbine disk 300 has several evenly distributed swirl vanes 310, and the inner side of the turbine disk 300 also has exhaust holes 320 located between adjacent swirl vanes 310. During use, fluid can be discharged along the channel formed by the swirl vanes 310 and the exhaust holes 320, improving the cooling effect.

[0030] In another embodiment, the bevel gear shaft structure further optimizes heat dissipation and cooling design. The bevel gear 100 has a bevel gear structure, with each discharge hole 120 located in the gap between the teeth of adjacent bevel gears 100. The discharge holes 120 radially penetrate the outer wall of the bevel gear 100 and extend to the inner side of the inner cavity 140, ensuring that cooling fluid can flow in from the outside of the gear and circulate within the inner cavity 140, thus making the cooling effect more significant.

[0031] To enhance fluid guidance, the flow channel holes 130 are arranged in a spiral oblique direction, with the spiral direction parallel to the oblique edge on the surface of the bevel gear 100. This design allows the cooling fluid to generate a swirling effect during flow, further improving cooling efficiency. Furthermore, the cooling guide plate 141 and the bevel gear 100 are integrally formed, made of ductile iron or alloy steel, possessing excellent high-temperature resistance and wear resistance, thereby improving the reliability of the equipment under long-term operating conditions.

[0032] In this embodiment, exhaust holes 320 are horizontally penetrating on both the inner and outer sides of the turbine disk 300, and arc-shaped swirl vanes 310 and exhaust holes 320 are provided. This not only increases the efficiency of exhaust, but also effectively avoids the problem of heat accumulation caused by fluid stagnation.

[0033] In the third embodiment, a stronger auxiliary cooling effect is provided. Specifically, the surface of the flange cap 400 is provided with several flange blades 410, and the flange blades 410 have an airfoil cross-section. This design can drive the surrounding airflow when the gear rotates, forming a convective heat dissipation effect. Furthermore, in this embodiment, the swirl vanes 310 and exhaust port 320 are optimized to allow fluid to circulate more smoothly inside the turbine disk 300, ensuring the efficient operation of the cooling system.

[0034] Through the optimized design of the above embodiments, this utility model can achieve efficient heat dissipation and cooling in synchronous motors, extend the service life of the equipment, and ensure operational stability under high-intensity working conditions.
