[0050] More specifically, a gasket is also provided between the connecting flange 222 and the oil inlet seat 21 to achieve the sealing connection between the two.
[0051] Optionally, both the first oil inlet pipe 10 and the oil inlet seat 21 are respectively fixed on the box cover 200 and the box body 300 through a welding process, so as to realize that the first oil inlet pipe 10 and the oil inlet seat 21 respectively penetrate and are sealingly connected to the box cover 200 and the box body 300.
[0052] In some embodiments, plugging members 70 are detachably connected to the oil inlet ports of the first oil inlet hole 101 and the second oil inlet hole 201 to prevent impurities from entering the oil circuit. During use, when selecting the first oil inlet hole 101 or the second oil inlet hole 201 as the external connection oil port, the corresponding plugging member 70 needs to be removed, and then the plugging member 70 of the other oil inlet hole remains to prevent oil leakage.
[0053] Optionally, the plugging member 70 is an internal hexagonal screw plug, and the plugging effect is better.
[0054] Please refer to Figure 2 , in some embodiments, the second oil inlet pipe 20 is further provided with a plurality of oil guide pipes 80. One end of the oil guide pipe 80 is connected to the second oil inlet hole 201, and the other end can be connected to the inside of the gearbox, so as to realize the diversion of the lubricating oil in the portable disassembly and assembly oil pipe structure to the inside of the gearbox to achieve the oil inlet of the gearbox.
