AI Technical Summary
The existing gear shaft structure is simple to design, and it is impossible to lubricate the gear position, resulting in severe wear, frequent replacement and high cost.
A new type of gear shaft with its own lubricating structure was designed. By setting oil storage tanks and oil outlet holes on the transmission shaft, lubrication is used to reduce gear wear.
The self-lubricating effect of the gear shaft is realized, which reduces gear wear, extends the service life of the gear shaft, and reduces replacement costs.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of transmission structures and relates to a gear shaft, in particular to a novel gear shaft. Background Art
[0002] The gear shaft is a transmission shaft with a gear structure. The gears on the shaft mesh with other gears. As the meshing transmission time goes by, the gear position will wear. The current gear shaft structure design is simple and the gear position cannot be lubricated. Therefore, the replacement speed of the worn gear shaft will be relatively frequent and the replacement cost will be relatively high. Summary of the invention
[0003] The utility model aims to solve the above problems existing in the prior art and provides a new gear shaft with a self-lubricating structure.
[0004] The purpose of the utility model can be achieved through the following technical solutions: a new type of gear shaft, including a transmission shaft and a gear plate integrally formed on the transmission shaft, the gear plate having a meshing portion on the peripheral wall, characterized in that a mounting groove is provided at the end of the transmission shaft, a central deep groove is provided on the groove wall of the mounting groove, an oil storage tank is inserted in the central deep groove, the oil storage tank is filled with grease, a plurality of oil outlet holes are provided on the peripheral wall of the inner end of the oil storage tank, and an oil outlet channel connected to the corresponding oil outlet hole is provided on the outer end surface of each meshing portion facing the transmission shaft.
[0005] In the above-mentioned novel gear shaft, the outer wall of the oil storage tank is in a step shape, and the central deep groove is a step groove structure.
[0006] In the above-mentioned novel gear shaft, a plug for blocking the oil storage tank is provided on the groove wall of the installation groove, and the plug is installed in the transmission shaft by screws.
[0007] In the above-mentioned novel gear shaft, an oil filling hole is provided in the middle of the outer end of the oil storage tank, and the inner end of the plug has a plugging portion that is inserted into the oil filling hole.
[0008] Compared with the prior art, the novel gear shaft has a self-lubricating effect, thereby achieving the advantage of reducing gear wear. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is a structural diagram of the new gear shaft.
[0010] In the figure, 1. transmission shaft; 2. gear plate; 3. meshing part; 4. center deep groove; 5. oil storage tank; 6. oil outlet hole; 7. oil outlet channel; 8. plug; 9. plugging part; 10. installation groove. DETAILED DESCRIPTION
[0011] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0012] like Figure 1 As shown, the novel gear shaft comprises a transmission shaft 1 and a gear plate 2 integrally formed on the transmission shaft 1, a meshing portion 3 is provided on the peripheral wall of the gear plate 2, the meshing portion 3 meshes with other gears, a mounting groove 10 is provided at the end of the transmission shaft 1, the mounting groove 10 is used for connecting other shafts, a central deep groove 4 is provided on the groove wall of the mounting groove 10, an oil storage tank 5 is inserted in the central deep groove 4, the oil storage tank 5 is filled with grease, a plurality of oil outlet holes 6 are provided on the peripheral wall of the inner end of the oil storage tank 5, an oil outlet channel 7 connected with the corresponding oil outlet hole 6 is provided on the outer end surface of each meshing portion 3 facing the transmission shaft 1, the transmission shaft 1 itself has a lubrication structure, the grease, that is, the grease forms a water-like liquefied grease after the transmission shaft 1 rotates at a high speed, and is thrown out of each oil outlet channel 7 under the action of centrifugal force to lubricate the meshing portion 3.
[0013] Preferably, the outer wall of the oil storage tank 5 is stepped, and the central deep groove 4 is a stepped groove structure.
[0014] Preferably, a plug 8 for blocking the oil storage tank 5 is provided on the groove wall of the installation groove 10, and the plug 8 is installed in the transmission shaft 1 by screws.
[0015] Preferably, an oil filling hole is opened in the middle of the outer end of the oil storage tank 5, and the inner end of the plug 8 has a plugging portion 9 that is inserted into the oil filling hole.
[0016] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0017] Although the terms such as transmission shaft 1, gear plate 2, meshing part 3, central deep groove 4, oil storage tank 5, oil outlet hole 6, oil outlet channel 7, plug 8, plugging part 9, mounting groove 10 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
