[0028] The embodiment of the utility model provides a transmission gear box with high efficiency lubrication.

[0029] See also Figure 1 and Figure 2 , including a box body 1, a side panel 2 is arranged on the outside of the box body 1, and threaded holes are opened at corresponding positions of the box body 1 and the side panel 2. The staff can use screws to thread the box body 1 and the side panel 2, which is convenient for the staff to subsequently inspect and replace the internal components of the box body 1.

[0030] Please refer to Figure 2. The outer surface of the side plate 2 is fixedly connected to a connecting ring 3, and the interior of the connecting ring 3 is rotatably connected to a rotating rod 4. The rotating rod 4 is rotatably connected to the side plate 2. The connecting ring 3 provides a limit and support for the rotation of the rotating rod 4, so that the rotating rod 4 can remain stable during the rotation process.

[0031] The rotating rod 4 passes through the box body 1 and is rotatably connected to the box body 1. The outer surface of the rotating rod 4 is fixedly connected to the bevel gear 2 5. The end of the rotating rod 4 located outside the box body 1 can be installed with a driving motor or other equipment according to actual needs. When the rotating rod 4 rotates, the bevel gear 2 5 will also rotate accordingly, thereby providing power for the subsequent rotation of the bevel gear 3 8 and the bevel gear 1 910.

[0032] The outer surface of the side panel 2 is fixedly connected with a fixing block 6, and the middle part of the fixing block 6 is rotatably connected with a transmission rod 7. The transmission rod 7 passes through the box body 1 and is rotatably connected with the box body 1. One end of the transmission rod 7 can be installed with a driving motor or other equipment according to actual needs. The fixing block 6 provides support and stability for the rotation of the transmission rod 7 to prevent the transmission rod 7 from shaking during the rotation process.

[0033] One end of the transmission rod 7 is fixedly connected to a bevel gear three 8, which meshes with the bevel gear two 5. When the bevel gear two 5 rotates, the bevel gear three 8 will also rotate under the action of meshing. The rotation of the bevel gear three 8 can drive the transmission rod 7 to rotate, thereby realizing efficient transmission between gears.

[0034] Please refer to Figures 2, 3, 4, 5 and 6. A lubrication mechanism 9 is provided inside the housing 1. The lubrication mechanism 9 includes an oil storage cylinder 901 fixedly connected to the side plate 2. The position of the oil storage cylinder 901 can be installed according to actual lubrication needs. The drawings in this application are only for style reference and are not used as actual production templates. A certain amount of lubricating oil is stored in the oil storage cylinder 901. When the lubricating oil drips from the inside of the oil storage cylinder 901, it can lubricate the gears inside the housing 1.

[0035] Please refer to Figures 2 and 3. The oil storage cylinder 901 is internally slidably connected with a protective plug 911. The protective plug 911 can protect the lubricating oil inside the oil storage cylinder 901 and prevent dust and other particles from falling into the oil storage cylinder 901 through the top surface of the oil storage cylinder 901 and contaminating the lubricating oil. The staff can pull the protective plug 911 out of the oil storage cylinder 901 to observe and add lubricating oil.

[0036] See also Figure 5 An oil separator 902 is fixedly connected to the inside of the oil storage cylinder 901. The oil separator 902 can block the lubricating oil inside the oil storage cylinder 901. An oil dripping port is opened in the middle of the oil separator 902. The speed of the lubricating oil dripping can be controlled by controlling the opening and closing of the oil dripping port, thereby realizing automatic addition of the lubricating oil and avoiding waste of the lubricating oil.

[0037] The interior of the oil reservoir 901 is provided with a swing rod 903. The end of the swing rod 903 just below the oil dripping port is equipped with a baffle for opening and closing the oil dripping port, and the baffle is covered with an oil-proof coating. The oil reservoir 901 can limit the swing rod 903 so that the swing rod 903 can only move horizontally to avoid excessive pressure of the lubricating oil forcing the baffle to separate from the oil dripping port. When the swing rod 903 swings, the baffle and the oil dripping port will be misaligned, and a slight gap will be generated between the two. The lubricating oil drips along the gap to the bottom end of the oil reservoir 901, and finally drips from the oil reservoir 901 onto the bevel gear 25, thereby realizing automatic lubrication of the gears. There is no need to manually add lubricant to the gears, which reduces the workload of the staff.

[0038] See also Figure 3 , Figure 4 and Figure 5 One end of the swing rod 903 is fixedly connected with a probe 1 904, and the probe 2 907 is adapted to the probe 1 904. Through the setting of the probe 1 904 and the probe 2 907, the speed of the lubricating oil dripping can be controlled. The smaller the contact area between the probe 1 904 and the probe 2 907, the slower the oil dripping speed. The specific oil dripping speed can be changed according to the actual needs of the gearbox by changing the contact area between the probe 1 904 and the probe 2 907.

[0039] See also Figure 2 and Figure 3 The inner top wall of the box body 1 is rotatably connected with a driven rod 905, and the bottom end of the driven rod 905 is fixedly connected with a bevel gear 1 910, and the bevel gear 2 5 is meshed with the bevel gear 1 910. The rotation of the bevel gear 2 5 can drive the bevel gear 1 910 to rotate, and the rotation of the bevel gear 1 910 drives the driven rod 905 to rotate, and the rotation of the driven rod 905 drives the driven ring 906 to rotate.

[0040] The outer surface of the driven rod 905 is fixedly connected to a driven ring 906, and the outer surface of the driven ring 906 is fixedly connected to a probe 2 907. The rotation of the driven ring 906 drives the probe 2 907 to rotate, and the probe 2 907 moves the probe 1 904, so that the baffle at one end of the swing rod 903 removes the obstruction to the oil dripping port, allowing the lubricating oil to drip from the gap between the two.

[0041] See also Figure 5 and Figure 6 The inner wall of the oil storage cylinder 901 is fixedly connected with a hinge block 908, and the hinge block 908 is hinged to the swing rod 903. When the probe 1 904 is moved by the probe 2 907, one end of the swing rod 903 will be driven to move. Through the setting of the hinge block 908, the hinge block 908 provides a fulcrum for the swing rod 903, so that the baffle connected to the other end of the swing rod 903 moves, thereby separating it from the oil drip port opened by the oil separator 902.

[0042] A return spring 909 is fixedly connected to the inner wall of the oil storage cylinder 901, and the end of the return spring 909 away from the oil storage cylinder 901 is fixedly connected to the swing rod 903. Through the setting of the return spring 909, a certain resistance can be provided for the swing of the swing rod 903 to prevent the swing rod 903 from swinging too much, which will cause a large gap between the baffle and the oil dripping port and cause waste of lubricating oil. At the same time, the return spring 909 can also push the swing rod 903 to reset, so that the probe 1 904 can keep the baffle at one end of the swing rod 903 to cover the oil dripping port without being pushed by the probe 2 907.

[0043] When the utility model is in use, the staff first connects one end of the rotating rod 4 to the output shaft of the motor, starts the motor, and the rotating rod 4 starts to rotate inside the connecting ring 3. The rotating rod 4 rotates to drive the bevel gear 2 5 to rotate. Under the effect of meshing, the bevel gear 3 8 and the bevel gear 1 910 both start to rotate. The bevel gear 3 8 drives the rotation of the transmission rod 7, thereby realizing the transmission effect of the gear box. The rotation of the bevel gear 1 910 drives the driven rod 905 to rotate. The rotation of the driven rod 905 drives the driven ring 906 to rotate. 906 drives probe 2 907 to rotate, probe 2 907 rotates to move probe 1 904, and probe 1 904 drives one end of the swing rod 903 to swing. Through the limit of the hinge block 908, the baffle connected to the other end of the swing rod 903 will be separated from the oil dripping port, thereby creating a gap. The lubricating oil flows along the gap from the oil separator 902 through the oil outlet at the bottom of the oil storage cylinder 901 to the bevel gear 2 5, thereby realizing automatic lubrication of the gears. There is no need to manually add lubricant to the gears, which reduces the workload of the staff.
