Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical transmission components and relates to a gear, in particular to a new type of gear. Background Art

[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 purpose of the utility model is to provide a new gear with self-lubricating function 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 type of gear, including a wheel disc and a plurality of gear teeth formed on the outer ring of the wheel disc, characterized in that a groove is provided at the end of the wheel disc, and the groove wall surface of the groove extends inward to provide an oil ring groove, an oil storage pan is installed in the groove, the oil storage pan is composed of a disc body and a disc cover clamped on the disc body, the disc cover is provided with a plurality of oil outlet holes that are all connected to the oil ring groove, each of the oil outlet holes is arranged at intervals, and are respectively distributed in the same straight line with the corresponding gear teeth in the vertical direction, the outer end of the gear teeth portion has an oil outlet groove that is vertically opened inward and connected to the corresponding oil outlet hole through the oil ring groove, and the disc body has an oil storage cavity for storing grease.

[0006] In the above-mentioned novel gear, the inside of the disc body has a guide platform with a stepped longitudinal section.

[0007] In the above-mentioned novel gear, the disc body is mounted on the wheel disc by screws.

[0008] In the above-mentioned novel gear, a sealing ring is arranged between the disc body and the wheel disc.

[0009] Compared with the prior art, the novel gear has the advantage of good lubrication effect on the gear teeth. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0011] In the figure, 1, wheel disc; 2, gear tooth portion; 3, oil ring groove; 4, disc body; 5, disc cover; 6, oil outlet hole; 7, oil outlet groove; 8, oil storage chamber; 9, guide platform. DETAILED DESCRIPTION

[0012] 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.

[0013] like Figure 1 As shown, the new gear comprises a wheel disc 1 and a plurality of gear teeth 2 formed on the outer ring of the wheel disc 1. A groove is provided at the end of the wheel disc 1. The groove wall surface of the groove extends inward to form an oil ring groove 3. An oil storage pan is installed in the groove. The oil storage pan consists of a disc body 4 and a disc cover 5 clamped on the disc body 4. The disc cover 5 is provided with a plurality of oil outlet holes 6 which are all connected with the oil ring groove 3. The oil outlet holes 6 are arranged at intervals and are respectively distributed in the same straight line with the corresponding gear teeth 2 in the vertical direction. The outer end of the gear teeth 2 has an oil outlet groove 7 which is vertically opened inward and connected with the corresponding oil outlet hole 6 through the oil ring groove 3. The disc body 4 has an oil storage cavity 8 containing grease. During the high-speed meshing process of the gear teeth 2, the entire gear rotates at a high speed to generate heat. The grease is decomposed by the heat to form oil. Through centrifugal force, the oil flows along the oil ring groove 3 and is thrown out of the oil outlet groove 7 to lubricate the gear teeth 2.

[0014] To elaborate further, the inside of the disc body 4 is provided with a guide platform 9 having a stepped longitudinal section. After the oil is formed, the guide platform 9 rotates at a high speed to form a rotating body with a high flow rate, thereby increasing the oil ejection speed and forming a rapid lubrication effect.

[0015] Preferably, the disc body 4 is mounted on the wheel disc 1 by screws.

[0016] Preferably, a sealing ring is provided between the disc body 4 and the wheel disc 1 .

[0017] 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.

[0018] Although the terms such as wheel disc 1, gear part 2, oil ring groove 3, disc body 4, disc cover 5, oil outlet hole 6, oil outlet groove 7, oil storage cavity 8, guide platform 9 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.
