Specific implementation mode

[0014] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0015] As Figure 1 、 Figure 2 、 Figure 3 shown, this gearbox with quick lubrication includes a gearbox main body 1, a gear shaft 2, and a plurality of bearings 3 located on the gearbox main body 1 for assisting the rotation of the gear shaft 2. A plurality of oil injection holes 4 are opened on the gearbox main body 1. An oil injection pipeline 5 is arranged in the oil injection hole 4 and extends through the oil injection hole 4 to both sides of the gear shaft 2. A linkage pipeline 6 is arranged at the lower end of the oil injection pipeline 5. A sponge body 7 for absorbing and storing lubricating oil is arranged between the linkage pipeline 6 and the bearing 3. An extrusion plate 8 is arranged at one end of the linkage pipeline 6, and the extrusion plate 8 abuts against the sponge body 7.

[0016] Further details, a storage bin 9 for storing the sponge body 7 and limiting the extrusion plate 8 is arranged on one side of the bearing 3. The linkage pipeline 6 passes through the storage bin 9 and can drive the extrusion plate 8 to slide in the storage bin 9.

[0017] Further details, an oil injection funnel 10 is arranged at the upper end of the oil injection pipeline 5.

[0018] Further details, a pull rod 11 is arranged on the linkage pipeline 6, and the pull rod 11 extends out of the gearbox main body 1.

[0019] Further details, an elastic element 12 with an elastic reset function is arranged in the storage bin 9. One end of the elastic element 12 is connected to the inner wall of the storage bin 9, and the other end is connected to the extrusion plate 8.

[0020] During use, lubricating oil is injected through the oil filling funnel 10. The lubricating oil flows through the oil filling pipe 5 and the linkage pipe 6 to the sponge body 7 and accumulates in the sponge body 7. When the gearbox is operating, the bearing 3 rotates continuously, and the surface of the bearing 3 constantly contacts the sponge body 7, causing lubricating oil to adhere to the surface of the bearing 3. At this time, the pull rod 11 is pushed inward to drive the linkage rod to move, so that the pressing plate 8 presses the sponge body 7, causing the lubricating oil in the sponge body 7 to enter the bearing 3, thereby lubricating the inside of the bearing 3.

[0021] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains may make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0022] Although terms such as 1. gearbox body 1; 2. gear shaft 2; 3. bearing 3; 4. oil filling hole 4; 5. oil filling pipe 5; 6. linkage pipe 6; 7. sponge body 7; 8. pressing plate 8; 9. storage bin 9; 10. oil filling funnel 10; 11. pull rod 11; 12. elastic element 12 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
