Description

Technical Field

[0001] The utility model relates to the technical field of bevel gear transmission, and specifically, to an efficient heat dissipation straight bevel gear transmission device. Background Art

[0002] In the field of mechanical engineering, a transmission device is a key component for realizing power transmission and motion conversion. As an important transmission form, the bevel gear transmission device has a unique position and wide applications. Bevel gear transmission is usually used for power transmission between intersecting shafts, which can change the transmission direction and speed ratio, and it plays an important role in many industries.

[0003] In the case of high-speed operation and heavy load of the existing bevel gear transmission device, a large amount of heat will be generated during the meshing process of the gears. If this heat cannot be dissipated in time, it will cause the temperature of the gears to continuously rise, which will further have an adverse impact on the service life and transmission efficiency of the gears. In addition, since the gears are only supported by one transmission shaft and are close to the frame in position, this structure makes it difficult for the heat to dissipate smoothly. Moreover, in this case, the accumulation of heat may also cause deformation of the gears, further affecting the meshing accuracy of the gears. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the above-mentioned disadvantages and provide an efficient heat dissipation straight bevel gear transmission device;

[0005] To achieve the above purpose, the utility model provides an efficient heat dissipation straight bevel gear transmission device, including a main frame, a motor bracket fixedly connected to the surface of the main frame. A transmission shaft is rotatably connected to the inner wall of the main frame. A driving bevel gear for transmitting power is provided at the end of the transmission shaft. A driven bevel gear for cooperating with the rotation of the driving bevel gear is provided along the outer edge of the driving bevel gear. A support shaft for supporting the rotation of the driven bevel gear is provided at the bottom of the driven bevel gear. A connecting shaft that can place the driven bevel gear in a hollow position is provided on the inner wall of the main frame. The bottom of the connecting shaft is fixedly connected to the top of the driven bevel gear. A plurality of heat dissipation fins for absorbing the heat of the driven bevel gear are provided on the surface of the driven bevel gear and the connecting shaft. Since the rotation of the transmission shaft can make the driving bevel gear drive the driven bevel gear to rotate, and the setting of the support shaft and the connecting shaft can make the driven bevel gear located in the middle position of the inner cavity of the main frame. Since the heat generated during the rotation of the driven bevel gear will be absorbed by the heat dissipation fins, the effect of dissipating heat from the driven bevel gear is achieved.

[0006] As a further improvement of this technical solution, a motor for driving the transmission shaft to rotate is provided in the inner cavity of the motor bracket, and the output end of the motor is connected to the transmission shaft by a motor shaft.

[0007] As a further improvement of this technical solution, a rotating shaft for driving the device to work is provided at one end of the connecting shaft away from the connecting shaft, and the rotating shaft rotates on the top of the main frame.

[0008] As a further improvement of this technical solution, a driving gear is fixedly connected to the surface of the transmission shaft. An outer edge of the driving gear is meshed with a transmission gear, an outer edge of the transmission gear is meshed with a driven gear, and a fan blade for heat dissipation is provided at one end of the driven gear close to the driven bevel gear. The transmission gear and the driven gear rotate on the inner wall of the main frame.

[0009] As a further improvement of this technical solution, a groove is formed on the surface of the main frame, and a ventilation frame is provided on the inner wall of the groove.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] In this high-efficiency heat dissipation straight bevel gear transmission device, by adding a support shaft and a connecting shaft, the driven bevel gear is located at the middle position of the inner cavity of the main frame, avoiding the problem of difficult heat dissipation caused by being supported by only one transmission shaft and being close to the frame, improving the heat dissipation conditions. Multiple heat dissipation fins provided on the surface of the driven bevel gear and the connecting shaft can effectively absorb the heat generated when the driven bevel gear rotates, providing a direct way for heat dissipation, timely and effectively dissipating the heat generated by gear meshing, preventing the gear temperature from being too high, and thus reducing the occurrence probability of damage phenomena such as gear wear, pitting, and scuffing caused by high temperature.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work shall fall within the protection scope of the present utility model. Embodiment

[0021] Please refer to Figures 1-4 As shown in the figure, this embodiment provides an efficient heat dissipation straight bevel gear transmission device, including a main body frame 1 and a motor bracket 11 fixedly connected to the surface of the main body frame 1. In the existing bevel gear transmission device, when it is in high-speed operation and heavy load, a large amount of heat will be generated during the meshing of the gears. If this heat cannot be dissipated in time, it will cause the temperature of the gears to continuously rise, which will further have an adverse impact on the service life and transmission efficiency of the gears. In addition, since the gears are only supported by a single transmission shaft and are close to the frame, this structure makes it difficult for the heat to dissipate smoothly. Moreover, in this case, the accumulation of heat may also cause the deformation of the gears, further affecting the meshing accuracy of the gears. Therefore, a transmission shaft 21 is rotatably connected to the inner wall of the main body frame 1. The end of the transmission shaft 21 is provided with a driving bevel gear 210 for transmitting power. The outer edge of the driving bevel gear 210 is provided with a driven bevel gear 22 for cooperating with its own rotation. The bottom of the driven bevel gear 22 is provided with a support shaft 220 for supporting its own rotation. The inner wall of the main body frame 1 is provided with a connecting shaft 23 that can place the driven bevel gear 22 in a hollow position. The bottom of the connecting shaft 23 is fixedly connected to the top of the driven bevel gear 22. The surface of the driven bevel gear 22 and the connecting shaft 23 are provided with a plurality of heat dissipation fins 221 for absorbing the heat of the driven bevel gear 22. Since the rotation of the transmission shaft 21 can drive the driving bevel gear 210 to drive the driven bevel gear 22 to rotate, and the settings of the support shaft 220 and the connecting shaft 23 can place the driven bevel gear 22 in the middle position of the inner cavity of the main body frame 1. Since the heat generated when the driven bevel gear 22 rotates will be absorbed by the heat dissipation fins 221, the effect of dissipating heat from the driven bevel gear 22 is realized. The rotation of the transmission shaft 21 will drive the driving bevel gear 210 to rotate, and the rotation of the driving bevel gear 210 will drive the driven bevel gear 22 to rotate, while changing the power transmission direction. Moreover, the connecting shaft 23 at the top of the driven bevel gear 22 and the support shaft 220 at the bottom of the driven bevel gear 22 can support the driven bevel gear 22.

[0022] The improvement of this embodiment lies in:

[0023] Considering that in the existing bevel gear transmission device, a large amount of heat is generated during the meshing of gears when it is running at high speed and under heavy load. If this heat cannot be dissipated in time, it will cause the temperature of the gears to continuously rise, which will further have an adverse impact on the service life and transmission efficiency of the gears. In addition, since the gears are only supported by one transmission shaft and are close to the frame, this structure makes it difficult for heat to dissipate smoothly. Moreover, in this case, the accumulation of heat may also cause the deformation of the gears, further affecting the meshing accuracy of the gears. Therefore, by adding the support shaft 220 and the connecting shaft 23, the driven bevel gear 22 is located in the middle of the inner cavity of the main frame 1, avoiding the problem of difficult heat dissipation caused by being supported by only one transmission shaft 21 and being close to the frame, improving the conditions for heat dissipation. The driven bevel gear 22 and the connecting shaft 23 are provided with a plurality of heat dissipation fins 221 on the surface, which can effectively absorb the heat generated when the driven bevel gear 22 rotates, providing a direct way for heat dissipation, dissipating the heat generated by gear meshing in a timely and effective manner, preventing the gears from overheating, and thus reducing the occurrence probability of damage phenomena such as gear wear, pitting, and scuffing caused by high temperature.

[0024] In order to enable the transmission shaft 21 to rotate and drive the transmission shaft 21 to rotate, therefore, a motor 2 for driving the transmission shaft 21 to rotate is provided in the inner cavity of the motor bracket 11. The output end of the motor 2 is connected to the transmission shaft 21 using a motor shaft. By the operation of the motor 2, it can drive the motor shaft to make the transmission shaft 21 rotate.

[0025] In order to enable the rotation of the driven bevel gear 22 to drive the device to move by the connecting shaft 23, therefore, a rotating shaft 24 for driving the device to work is provided at one end of the connecting shaft 23 away from the connecting shaft 23. The rotating shaft 24 rotates on the top of the main frame 1. By the rotation of the driven bevel gear 22, the connecting shaft 23 can rotate on the inner wall of the main frame 1, and the rotation of the connecting shaft 23 can make the rotating shaft 24 rotate, and the rotation of the rotating shaft 24 can drive the device to rotate.

[0026] In order to enable the heat dissipation fins 221 to dissipate their own heat after absorbing the heat of the driven bevel gear 22, therefore, a driving gear 3 is fixedly connected to the surface of the transmission shaft 21. The outer edge of the driving gear 3 is meshed with a transmission gear 31, and the outer edge of the transmission gear 31 is meshed with a driven gear 32. A fan blade 320 for heat dissipation is provided at one end of the driven gear 32 close to the driven bevel gear 22. The transmission gear 31 and the driven gear 32 rotate on the inner wall of the main frame 1. By the rotation of the transmission shaft 21, the driving gear 3 can rotate, and the rotation of the driving gear 3 can make the transmission gear 31 rotate. Since the rotation of the transmission gear 31 can make the driven gear 32 rotate, the rotation of the driven gear 32 can drive the fan blade 320 to rotate. Since the rotation of the fan blade 320 can make the air inside the main frame 1 flow, it can promote the heat absorbed by the heat dissipation fins 221 to be quickly dissipated.

[0027] In order to enable the air inside the main body frame 1 to circulate quickly and the heat inside to be transferred out of the main body frame 1, grooves are provided on the surface of the main body frame 1, and ventilation frames 12 are provided on the inner walls of the grooves. When the fan blades 320 rotate, the air outside the main body frame 1 can enter the main body frame 1 through the ventilation frames 12, so that the air inside the main body frame 1 circulates.

[0028] When the high-efficiency heat dissipation straight bevel gear transmission device of the present utility model is in specific use, the rotating shaft 24 is connected to the device that needs to move. The operation of the motor 2 can drive the motor shaft to rotate the transmission shaft 21. The rotation of the transmission shaft 21 will drive the rotation of the driving bevel gear 210. The rotation of the driving bevel gear 210 will drive the rotation of the driven bevel gear 22, and at the same time change the direction of power transmission. The rotation of the driven bevel gear 22 can make the connecting shaft 23 rotate on the inner wall of the main body frame 1, and the rotation of the connecting shaft 23 can make the rotating shaft 24 rotate. The rotation of the rotating shaft 24 can drive the device to rotate. The heat generated when the driven bevel gear 22 rotates will be absorbed by the heat dissipation fins 221. At the same time, the rotation of the transmission shaft 21 can make the driving gear 3 rotate, and the rotation of the driving gear 3 can make the transmission gear 31 rotate. Since the rotation of the transmission gear 31 can make the driven gear 32 rotate, the rotation of the driven gear 32 can drive the fan blades 320 to rotate. Since the rotation of the fan blades 320 can make the air inside the main body frame 1 circulate, the heat absorbed by the heat dissipation fins 221 can be quickly dissipated.
