[0002] As we all know, gear meshing transmission is one of the transmission modes in the field of mechanical transmission, which mainly realizes mutual transmission between components through the meshing of the teeth of two gears.

[0003] However, in the actual transmission process, we found that under long-term mechanical transmission of the gear teeth of the two gears, the gear teeth are extremely prone to wear, resulting in reduced transmission efficiency and affecting use. Summary of the invention

[0004] The utility model aims to provide a new gear with reduced wear and improved use efficiency in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a new gear, including a wheel disc with multiple gear teeth, characterized in that an annular oil groove is opened on one side of the wheel disc, the side position of the wheel disc has an outer cone extending obliquely, and an inner cone extends at the position adjacent to the outer cone on this side of the wheel disc, the annular oil groove is located between the outer cone and the inner cone, an annular oil inlet channel which is obliquely arranged and communicates with the annular oil groove is formed between the inner cone and the outer cone, the longitudinal section of the annular oil inlet channel is a straight line inclined downward from the outer end to the inner end, the outer end of the annular oil inlet channel has a flat annular groove, the inner cone and the outer cone are provided with sealing plates connected to the flat annular groove, the sealing plate is provided with an oil filling hole at the position corresponding to the flat annular groove, each of the gear teeth is obliquely provided with an oil outlet hole connected to the annular oil groove, and the annular oil inlet channel is filled with grease.

[0006] In the above-mentioned novel gear, a plug is provided in the oil filling hole.

[0007] In the above-mentioned novel gear, the outer end of the sealing plate has a connecting platform which is flush with the outer frustum, and the connecting platform and the outer frustum are connected by a plurality of screws.

[0008] In the above-mentioned novel gear, a flat washer is provided between the connecting platform and the outer cone.

[0009] Compared with the prior art, the new gear has the advantages of good lubrication effect and increased service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a cross-sectional view of the new gear.
