Description

Technical Field

[0001] The present invention relates to the technical field of gear transmission, and in particular to a gear transmission system. Background Art

[0002] As the core power unit of mechanical equipment, the stability and reliability of the engine's performance are directly related to the success or failure of the equipment's operation. The engine gear transmission system is a key subsystem for transmitting power, regulating speed and torque inside the engine, and plays an indispensable role in the engine's operation. At present, in actual applications, the engine gear transmission system has achieved efficient power transmission with its compact structural design, providing a certain guarantee for the stable operation of the engine. However, there are still many problems that need to be solved in the lubrication link. Since the gear transmission system is arranged inside the engine, the space is very limited and the structure is compact, which makes the addition of lubricating oil extremely difficult. Under the existing technology, the replenishment of lubricating oil to the system often relies on professionals using specific tools and manual filling through narrow inspection ports. Not only is the operation process cumbersome, but it also requires extremely high technical skills of the operator. A slight mistake may lead to inaccurate lubricating oil filling or contamination of other precision components inside the engine. At the same time, the existing methods for judging whether the gear transmission system is short of lubricating oil are relatively primitive, and most of them rely on manual regular inspections, such as observing the oil level indicator, checking the color and viscosity changes of the lubricating oil, or relying on experience to judge the noise and vibration conditions during gear operation. However, this manual judgment method has great limitations. On the one hand, the loss of lubricating oil is affected by many complex factors such as engine operating conditions, operating time, ambient temperature, etc. Manual observation is difficult to accurately capture subtle changes in lubricating oil consumption, and it is very easy to make mistakes in judgment. On the other hand, during the operation of the equipment, the engine may be in a state of continuous operation for a long time. There are time intervals in manual inspection, and it is impossible to monitor the lubricating oil status in real time. Once the manual judgment is biased and the lack of lubricating oil is not discovered in time, the gears will run at high speed without effective lubrication, which will aggravate the wear of the gear surface, leading to faults such as tooth surface bonding and pitting. In severe cases, it may even cause gear breakage, causing the entire gear transmission system to fail, thereby threatening the safe operation of the engine and even the equipment. In addition, in some special equipment, such as deep-sea operation equipment, aerial work machinery, nuclear industry or aerospace equipment, etc., due to their special working environment or limited installation location, it is difficult to frequently disassemble, repair and replenish lubricating oil. The existing gear transmission system lacks the function of automatically adding lubricating oil, and cannot replenish lubricating oil in real time and accurately according to the actual needs of the system, and it is difficult to achieve self-lubricating performance. This not only greatly increases maintenance costs and manpower investment, but also seriously restricts the stability and reliability of engine operation, causing many inconveniences in the use of the equipment, and may even cause major failures due to untimely lubrication, resulting in immeasurable economic losses and safety hazards.

[0014] Beneficial effects of the present invention: 1. This gear transmission system adopts a closed-loop lubricating oil circulation cooling architecture to achieve efficient heat dissipation. The transmission mechanism provides power for the heat dissipation system. The unique design of the pumping spiral blades and the internal pump suction pipe improves the efficiency of lubricating oil suction and avoids cavitation. The heat conducting coil is arranged in a serpentine shape and fits tightly to the shell. The aluminum or copper material accelerates heat conduction. It is equipped with heat dissipation fins and semiconductor coolers, and adopts a multi-pronged approach from passive heat dissipation to active cooling. The oil state sensor monitors the oil temperature in real time, and the controller automatically adjusts the cooling intensity to ensure the stability of the lubricating oil temperature.

Once the oil level is insufficient or the performance is degraded, the system responds immediately by switching the dual solenoid valves, closing the heat dissipation circuit, and opening the self-lubricating oil guide group. The lubricating oil guide pipe rack has been optimized through fluid mechanics to accurately distribute the lubricating oil to each gear and transmission component. Special nozzles ensure uniform coverage of the lubricating oil, forming a dynamic oil film of ideal thickness, effectively reducing the friction coefficient. The controller can also dynamically adjust the pumping pressure and the opening and closing time of the solenoid valve according to the working conditions, ensuring optimal lubrication under various complex working conditions, reducing gear wear, and significantly extending the service life of the equipment. 3. This system achieves dynamic coordination of heat dissipation and lubrication functions through the intelligent switching mechanism of dual solenoid valves. Lubrication is prioritized at startup, heat dissipation is emphasized during stable operation, and the circulation mode is automatically adjusted when the load changes. Multi-sensor data fusion ensures accurate and efficient mode switching. The power sharing design uses the gear transmission system's own power to drive the pumping group, simplifying the structure and reducing energy consumption. The self-lubricating heat dissipation mechanism is integrated into the housing, reducing pipe connections and reducing the risk of leakage. At the same time, the fail-safe mechanism automatically limits engine power and alarms when the liquid level is too low or the oil temperature is abnormal, preventing major failures. Comprehensive collaborative optimization reduces the need for manual maintenance, reduces equipment downtime and repair costs, and improves overall operational economy and reliability.

DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0018] A gear transmission system includes a housing 1, a spur gear set 3 being rotatably connected to the upper front end of the housing 1, a bevel gear set 4 being rotatably connected to the lower front end of the housing 1, the bevel gear set 4 being meshed with the spur gear set 3, and a self-lubricating heat dissipation mechanism 2 being fixedly mounted on one side of the back of the housing 1; The self-lubricating heat dissipation mechanism 2 includes a supply mechanism 21, a transmission mechanism 22, a heat conducting mechanism 23 and a self-lubricating oil guide group 24. The supply mechanism 21 is fixedly mounted on the lower end of one side of the shell 1, and the transmission mechanism 22 is movably mounted on the upper end of the back of the shell 1. The heat conducting mechanism 23 is fixedly mounted on the outer surface of the shell 1 and the input end is connected to the supply mechanism 21. The self-lubricating oil guide group 24 is fixedly mounted on the front of the shell 1. The input end of the self-lubricating oil guide group 24 is connected to the output end of the supply mechanism 21. The output end of the self-lubricating oil guide group 24 is arranged on one side of the spur gear group 3, the bevel gear group 4 and the transmission mechanism 22. An oil state sensor 25 is fixedly mounted on the middle part of the shell 1. When the gear transmission system is working, the engine power is transmitted to the spur gear group 3 at the upper end of the front of the shell 1, and the torque is transmitted to the bevel gear group 4 at the lower end through meshing. After the speed and torque adjustment are completed, the spur gear set 3 drives the first bevel gear 223 in the transmission mechanism 22 to rotate, and drives the rotating shaft 2122 to rotate through the second bevel gear 224 and the synchronous belt 226, thereby providing power for the self-lubricating heat dissipation mechanism 2. In the supply mechanism 21, the pumping group 212 is driven by the rotating shaft 2122 to suck and transport the lubricating oil in the tank 211. Under normal working conditions, the heat dissipation solenoid valve 231 is opened, and the lubricating oil is dissipated through the heat conduction coil 232 of the heat conduction mechanism 23 and then flows back to the tank 211; when the oil state sensor 25 in the middle of the shell 1 detects that the lubricating oil is lacking or the performance is degraded, the controller 213 closes the heat dissipation solenoid valve 231 and opens the self-lubricating solenoid valve 243. The lubricating oil is accurately transported to the surface of the spur gear set 3, the bevel gear set 4 and the transmission mechanism 22 through the self-lubricating oil guide group 24, forming a lubricating film, thereby realizing automatic lubrication and efficient heat dissipation functions.

[0019] Combine Figure 3-Figure 8 As shown, the supply mechanism 21 includes a tank body 211, which is fixedly connected to the lower end of one side of the shell 1, and a pumping group 212 is fixedly installed inside the tank body 211. The output end of the pumping group 212 is connected to the heat conduction mechanism 23 and the input end of the self-lubricating oil guide group 24, and the input end of the pumping group 212 is connected to the bottom of the tank body 211. A controller 213 is fixedly installed in the middle of the top rear side of the tank body 211, and a refueling pipe 214 is fixedly connected to one side of the top of the tank body 211. The top of the refueling pipe 214 is threadedly connected to a sealing button cover 215. A fixing part 216 is fixedly installed on one side of the bottom of the tank body 211, and a liquid level sensor 217 is fixedly installed on the top of the fixing part 216.

[0020] According to the technical solution in the embodiment of the present application, during the use of the device, its supply mechanism 21 assumes the core functions of lubricating oil storage, delivery and monitoring in the gear transmission system. The tank body 211 is fixed to the lower end of one side of the shell 1 as a lubricating oil storage container. The refueling pipe 214 on the top is convenient for manual replenishment of lubricating oil. The sealing button cover 215 ensures that the lubricating oil is not contaminated by the outside world during storage. A liquid level sensor 217 is installed on the fixing part 216 at the bottom of the tank body 211 to continuously monitor the oil level. When it is detected that the amount of lubricating oil is lower than the set threshold, a signal is transmitted to the tank body 211. The controller 213 at the top rear side serves as the system's "command center." It controls the start and stop of the pumping group 212 based on received signals or data from the oil status sensor 25. Driven by the transmission mechanism 22, the rotating shaft 2122 of the pumping group 212 rotates, driving the pumping spiral blades 2123 to draw lubricating oil from the bottom of the tank 211 through the suction groove 2124. The oil is then connected to the heat transfer mechanism 23 and the self-lubricating oil guide group 24 through the output end. This allows for heat dissipation circulation or precise lubrication supply of the lubricating oil according to system requirements, ensuring stable operation of the gear transmission system. Example 2

[0021] Combine Figure 4-Figure 8 As shown, the pumping group 212 includes an inner pump suction pipe 2121, which is fixedly installed in the middle of the bottom of the tank body 211. The inner pump suction pipe 2121 is rotatably connected to a rotating shaft 2122. The top of the rotating shaft 2122 passes through the tank body 211 and is connected to the transmission mechanism 22. The lower end of the inner pump suction pipe 2121 is rotatably connected to a pumping spiral blade 2123. The top of the pumping spiral blade 2123 is connected to the bottom of the rotating shaft 2122. The bottom of the inner pump suction pipe 2121 is equidistantly arranged in a ring shape with suction grooves 2124. The pumping spiral blade 2123 is arranged in a conical shape as a whole. The lower end of the inner pump suction pipe 2121 is also arranged in a conical shape. The output end of the inner pump suction pipe 2121 is respectively connected to the heat conduction mechanism 23 and the self-lubricating oil guide group 24.

[0022] In the technical solution of the embodiment of the present application, during the use of the pumping group 212, the inner pump suction pipe 2121 is fixed to the middle of the bottom of the tank body 211, and the suction groove 2124 arranged in an annular shape at the bottom is the entrance for the lubricating oil to enter. The rotating shaft 2122 passes through the tank body 211 and is connected to the transmission mechanism 22. When the transmission mechanism 22 is running, it drives the rotating shaft 2122 to rotate at a high speed, thereby driving the pumping spiral blade 2123 at the lower end of the inner pump suction pipe 2121 to rotate. Due to the pumping spiral blade 2123 and the lower end of the inner pump suction pipe 2121, the inner pump suction pipe 2121 is connected to the inner pump suction pipe 2121. Both are conical in shape, and the two cooperate to form a tapered flow channel. By utilizing the principles of fluid dynamics, a self-priming effect is generated during the rotation of the spiral blades, and the lubricating oil at the bottom of the tank body 211 is smoothly sucked into the inner pump suction pipe 2121 from the suction groove 2124. The sucked lubricating oil is pushed by the spiral blades and is transported through the output end of the inner pump suction pipe 2121 to the heat conduction mechanism 23 for heat dissipation according to system requirements, or is transported to the self-lubricating oil guide group 24 to achieve lubrication of the gear group and the transmission mechanism 22, thereby ensuring the stable operation of the lubricating oil circulation system.

[0023] Combine Figures 1-4 and Figure 7-Figure 8 As shown, the self-lubricating oil guide group 24 includes a fixed block 241, which is fixedly connected to the side of the front of the shell 1 close to the tank 211. The front end of the fixed block 241 is fixedly installed with a lubricating oil guide pipe rack 242. The output ends of the lubricating oil guide pipe rack 242 are respectively arranged on one side of the spur gear group 3 and the bevel gear group 4. The output end of the lubricating oil guide pipe rack 242 is also arranged on one side of the transmission mechanism 22. The input end of the lubricating oil guide pipe rack 242 is fixedly connected to a self-lubricating solenoid valve 243. The input end of the self-lubricating solenoid valve 243 is connected to the output end of the internal pump suction pipe 2121. The heat-conducting mechanism 23 includes a heat dissipation solenoid valve 231. The heat dissipation solenoid valve 231 is fixedly connected to the top side of the internal pump suction pipe 2121. The heat dissipation solenoid valve 231 is arranged on the top of the self-lubricating solenoid valve 243. The output end of the heat dissipation solenoid valve 231 is fixedly installed with a heat-conducting coil 232. The heat-conducting coil 232 is fixedly connected to the outer surface of the shell 1. The output end of the heat-conducting coil 232 is connected to the interior of the tank body 211.

[0024] According to the technical solution in the above embodiment of the present application, when the oil state sensor 25 detects that the lubricating oil is insufficient or the performance is degraded, the controller 213 issues a command to open the self-lubricating solenoid valve 243 and close the heat dissipation solenoid valve 231. The lubricating oil output from the internal pump suction pipe 2121 flows into the lubricating oil guide pipe rack 242 through the self-lubricating solenoid valve 243. The pipe rack is fixed to the fixed block 241 on the front of the shell 1. Its output end is aligned with the spur gear set 3, the bevel gear set 4 and the transmission mechanism 22, and the lubricating oil is accurately distributed to the surface of each component to form a lubricating film to reduce friction. Under normal operating conditions, the heat dissipation solenoid valve 231 is opened and the self-lubricating solenoid valve 243 is closed. After the lubricating oil is output from the internal pump suction pipe 2121, it enters the heat conduction coil 232 fixed on the outer surface of the shell 1 through the heat dissipation solenoid valve 231. The heat conduction coil 232 dissipates the heat carried by the lubricating oil through heat exchange with the external environment. The cooled lubricating oil flows back to the tank 211, completing the heat dissipation cycle, ensuring that the gear transmission system operates stably under good lubrication and suitable temperature conditions. Example 3

[0025] Combine Figures 1-4As shown, the transmission mechanism 22 includes a mounting frame 221, a driven synchronous wheel 222 and a first bevel gear 223. The mounting frame 221 is fixedly mounted on the upper back end of the shell 1, and the top of the mounting frame 221 is rotatably connected to the second bevel gear 224. The first bevel gear 223 is fixedly connected to the upper back end of the shell 1, and the front of the first bevel gear 223 is fixedly connected to the back end of the spur gear set 3. The first bevel gear 223 and the second bevel gear 224 are meshed and connected. The top of the second bevel gear 224 is fixedly connected to the active synchronous wheel 225. The driven synchronous wheel 222 is fixedly connected to the top of the rotating shaft 2122. The active synchronous wheel 225 and the driven synchronous wheel 222 are connected by a synchronous belt 226. A supporting seat 227 is fixedly mounted on the upper end of the side of the back of the shell 1 close to the tank body 211. The upper end of the rotating shaft 2122 is rotatably connected to the inside of the supporting seat 227. During the use of this device, when When the engine drives the spur gear set 3 to rotate, the first bevel gear 223 fixed thereon rotates synchronously, and through meshing with the second bevel gear 224, the horizontal rotation motion is converted into vertical rotation, driving the active synchronous wheel 225 installed on the top of the second bevel gear 224 to rotate. The active synchronous wheel 225 drives the driven synchronous wheel 222 through the synchronous belt 226, so that the rotating shaft 2122 fixedly connected to the driven synchronous wheel 222 rotates at high speed. The upper end of the rotating shaft 2122 is supported and positioned by the supporting seat 227 to ensure rotation stability, and the lower end extends to the pumping group 212 in the tank body 211, providing power for the pumping spiral blade 2123, thereby realizing the circulation of lubricating oil. This multi-stage transmission design not only cleverly utilizes the power of the gear set itself, but also accurately controls the speed through the meshing of the bevel gears and the transmission of the synchronous belt 226, providing stable and reliable power input for the self-lubricating heat dissipation mechanism 2, and ensuring the efficient operation of the entire system.

[0026] The operating principle and advantages of the present invention are as follows: the heat dissipation function of the gear transmission system is based on a closed-loop lubricating oil circulation cooling architecture, and efficient heat exchange is achieved through the collaboration of multiple components. The power source comes from the transmission mechanism 22. During use, when the spur gear set 3 is running, the coaxially connected first bevel gear 223 drives the second bevel gear 224 to rotate, driving the active synchronous wheel 225 to drive the driven synchronous wheel 222 through the synchronous belt 226, thereby causing the rotating shaft 2122 to rotate at high speed. The rotating shaft 2122 extends to the bottom of the inner pump suction pipe 2121, driving the conical pumping spiral blade 2123 to rotate. The spiral blade and the tapered design of the inner pump suction pipe 2121 form a tapered flow channel, which uses the principle of fluid dynamics to produce a self-priming effect, and smoothly sucks in the lubricating oil from the suction groove 2124 at the bottom of the tank body 211. This design not only avoids cavitation, but also improves the oil suction efficiency by optimizing the fluid path. After the lubricating oil enters the heat dissipation circuit through the internal pump suction pipe 2121, the heat dissipation solenoid valve 231 opens to guide the oil into the heat-conducting coil 232. The heat-conducting coil 232 adopts a serpentine layout and is close to the outer surface of the shell 1. Its aluminum or copper heat-conducting material accelerates heat conduction. The heat dissipation fins that can be installed on the outside enhance air convection by expanding the surface area. At the same time, semiconductor refrigerators and other refrigeration and cooling elements can be installed on the outside of the tank body 211 as needed. They can be started under high-temperature conditions and actively dissipate heat based on the Peltier effect. The three work together to quickly reduce the temperature of the lubricating oil and then flow back to the tank body 211 to form a cycle. The oil state sensor 25 monitors the oil temperature in real time. When the threshold is exceeded, the controller 213 increases the power of the semiconductor refrigerator to ensure that the system can maintain thermal balance under extreme conditions. The self-lubricating function relies on a closed-loop control system with real-time monitoring and precise oil supply. The liquid level sensor 217 is installed on the fixing part 216 at the bottom of the tank body 211 to continuously monitor the oil level. When it is lower than the set value, an alarm is triggered and lubricating oil is replenished through the filling pipe 214. The oil state sensor 25 determines whether the lubricating oil performance has declined by detecting parameters such as viscosity and impurity content. When any indicator is abnormal, the system enters the lubrication mode, the controller 213 closes the heat dissipation solenoid valve 231, opens the self-lubricating solenoid valve 243, and guides the lubricating oil into the self-lubricating mode. Lubricating oil guide group 24; The lubricating oil guide pipe frame 242 of the self-lubricating oil guide group 24 adopts a split-flow design. The internal channel is optimized by fluid mechanics to ensure that the lubricating oil is proportionally distributed to the spur gear group 3, the bevel gear group 4, and the transmission mechanism 22. The special nozzle at the outlet ensures that the lubricating oil evenly covers the gear surface, forming a dynamic oil film. This oil film supports the load through the fluid dynamic pressure effect and reduces the friction coefficient. The pumping pressure and the solenoid valve opening time are dynamically adjusted by the controller 213 according to the working conditions to ensure that the optimal lubricating film thickness can be formed under different conditions such as high speed and heavy load. This system achieves intelligent coordination between heat dissipation and lubrication through a dual-solenoid valve switching mechanism. During startup, the self-lubricating solenoid valve 243 is preferentially activated to quickly establish a lubricating oil film to protect the gears. After entering stable operation, the system switches to heat dissipation mode to reduce system temperature rise. When a sudden increase in load causes the oil temperature to rise, the frequency of the heat dissipation cycle is automatically increased. This dynamic adjustment is based on multi-sensor data fusion: the oil state sensor 25 provides temperature and viscosity data, the liquid level sensor 217 monitors the oil level, and the controller 213 uses an algorithm to calculate the optimal operating mode in real time. The power sharing design further improves system efficiency. The pumping group 212 and the gear transmission system share the same power source, achieving energy coupling through the transmission mechanism 22, avoiding the complexity of an additional power unit. Structurally, the self-lubricating heat dissipation mechanism 2 is integrated into the housing 1, reducing external piping connections and the risk of leakage. A fail-safe mechanism ensures reliability: when the liquid level is too low or the oil temperature is abnormal, the system automatically limits engine power and triggers an alarm to prevent catastrophic failure due to lubrication failure.
