However, the characteristics of transportation machinery are long working hours and heavy loads. Under high load and high speed working conditions, gears are prone to fatigue failure, which manifests as surface cracking, cracks and tooth surface shedding. These are mainly caused by poor lubrication.

[0003] The Chinese patent with application number 2019219243766 discloses a gear with good lubrication effect, including a gear body, a protective sleeve fixedly installed on the outside of the gear teeth of the gear body, a lubricating oil adding hole on the top surface of the gear body, a tooth groove on the side of the gear body, a rotating shaft and a scrap magnet sheet fixedly installed on the tooth groove, and a lubricating oil outlet hole is opened on the outer surface of the tooth groove between the rotating shaft and the scrap magnet sheet. A lubricating oil outlet hole is provided on the outside, and lubricating oil can be added to the gear in advance. When the gear is rotating and transmitting, the lubricating oil will move outward due to the centrifugal force generated by the rotation of the gear, and finally flow out through the lubricating oil outlet hole, performing good lubrication, without the need for manual addition of lubricating oil, and lubrication is carried out in real time with the gear working, and the lubricating effect is good.

[0004] The above patent solution has a good lubrication effect, but the above lubricating oil chamber is set inside the gear, and the lubricating oil is added through the lubricating oil adding hole. This structure makes the process of replenishing the lubricating oil of the gear take a long time, and the transportation machinery usually cannot be stopped for too long, so the existing technology cannot meet the working requirements of the transportation machinery.

[0021] like Figure 1-2 As shown, a gear assembly for transport machinery includes a gear body 1 and a mounting cover 2. An axial hole 3 is provided in the middle of the gear body 1 for connecting the drive shaft. An oil storage tank 4 is provided on the surface of the gear body 1. A concave annular portion 5 is provided in the middle of the oil storage tank 4. The annular portion 5 is arranged around the axial hole 3. An installation groove 6 is provided on the outer side of the annular oil storage tank 4. A first mounting hole 7 is provided on the mounting groove 6. A second mounting hole 8 is provided on the mounting cover 2. By installing the mounting cover 2 on the mounting groove 6, the annular oil storage tank 4 can be closed to form a closed lubrication system, which effectively prevents external contaminants such as dust and impurities from entering the oil storage tank 4, and ensures the cleanliness and lubrication effect of the lubricating oil. This design makes the process of adding and replenishing the lubricating oil simple and quick, without the need to stop the machine for too long, and meets the working requirements of the transport machinery.

[0022] Combination Figure 1 and Figure 4A connecting hole 9 is provided on the peripheral side wall of the oil storage tank 4, and the connecting hole 9 extends to the outer periphery of the gear body 1. The connecting hole 9 allows the lubricating oil to directly act on the meshing surface and contact surface of the gear, thereby ensuring real-time and effective lubrication of the gear, which can not only reduce the wear of the gear and extend its service life, but also improve the accuracy and efficiency of the gear transmission, and can ensure the continuous operation of the transportation machinery.

[0023] Combination Figure 3 A circulation channel 10 is provided on the annular portion 5, one end of the circulation channel 10 is connected to the oil storage tank 4, and the other end of the circulation channel 10 is connected to the shaft hole 3. The design of the circulation channel 10 allows the lubricating oil to flow from the oil storage tank 4 to the shaft hole 3 area, thereby lubricating the gear shaft and bearings. This design not only ensures the lubrication of the gear tooth surface, but also takes into account the lubrication requirements of the gear shaft and bearings, thereby improving the lubrication effect of the entire gear assembly and reducing wear and failures caused by poor lubrication. Since the lubricating oil can be evenly distributed on key parts such as the gear tooth surface, gear shaft and bearing, the friction and wear of these parts are reduced, thereby significantly extending the service life of the gear assembly. In addition, failures and downtime caused by poor lubrication are reduced, thereby reducing the maintenance cost of transportation machinery.

[0024] The circulation channel 10 is an open channel arranged on the surface of the annular portion 5. There are four open channels in total and they are evenly arranged around the shaft hole 3. The open channels form a strip groove structure on the surface of the annular portion 5, which can be easily cleaned. During the operation of the transport machinery, impurities or dirt may be mixed into the lubricating oil due to various reasons. These impurities and dirt may block the circulation channel 10 and affect the lubrication effect. The design of this open channel allows the staff to directly clean the channel to ensure the smoothness of the lubricating oil. The four open channels are evenly distributed around the shaft hole 3, which can ensure that the lubricating oil is evenly distributed inside the gear assembly and fully lubricate key parts such as the gear tooth surface, gear shaft and bearing. This uniform lubrication effect can not only reduce friction and wear, but also improve the transmission efficiency and service life of the gear assembly. Since the circulation channel 10 is easy to clean and can ensure the smoothness of the lubricating oil, it can reduce failures and downtime caused by poor lubrication, thereby reducing maintenance costs. In addition, since the lubricating oil can be recycled, the consumption and replacement frequency of the lubricating oil are reduced, further reducing maintenance costs.

[0025] A sealing gasket 11 is provided between the mounting cover 2 and the mounting groove 6. The sealing gasket 11 can effectively fill the small gap between the mounting cover 2 and the mounting groove 6, further preventing external dust, moisture, oil and other pollutants from entering the oil storage tank 4, and ensuring the cleanliness of the lubricating oil inside the gear. The presence of the sealing gasket can also prevent the lubricating oil from leaking from the gap between the mounting cover 2 and the mounting groove 6, ensuring that the lubricating oil is circulated inside the gear assembly, providing continuous lubrication for key parts such as the gear tooth surface, gear shaft and bearing. This helps to improve the efficiency and stability of the gear transmission.

[0026] The surface of the gear body 1 is provided with heat dissipation holes 12, which can effectively increase the heat dissipation area of ​​the gear surface, so that the heat generated by the gear when running at high speed can be quickly dissipated to the surrounding environment, thereby reducing the temperature of the gear. This heat dissipation design helps to reduce the deformation, wear or failure of the gear caused by overheating, improves the service life and reliability of the gear, reduces the working temperature of the gear, and can reduce problems such as material fatigue and thermal stress caused by high temperature, thereby reducing the failure rate of the gear. This is particularly important for transportation machinery that needs to work continuously for a long time, which helps to reduce downtime and maintenance costs.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
