[0008] Compared with the prior art, for the gear with automatic lubrication of the present utility model, by injecting oil into the oil storage cavity and automatically delivering the lubricating oil to the mating part between the gears during the rotation of the gears, the labor cost and time cost are reduced. Brief Description of the Drawings

[0009] Figure 1 is the main schematic diagram of the gear with automatic lubrication of the present utility model;

[0010] Figure 2 is the sectional view of the gear with automatic lubrication of the present utility model.

[0011] In the figure, 1 is the gear body; 2 is the mounting seat; 3 is the tooth; 4 is the oil injection hole; 5 is the first oil delivery pipe; 6 is the second oil delivery pipe; 7 is the oil outlet hole; 8 is the oil storage cavity; 9 is the first slope; 10 is the second slope; 11 is the sealing plug. Detailed implementation mode

[0012] The following are specific embodiments of the present utility model and in combination with the attached drawings, the technical solutions of the present utility model are further described, but the present utility model is not limited to these embodiments.

[0013] As Figure 1 、 Figure 2 shown, this self-lubricating gear includes a gear body 1, a mounting seat 2 connected to the gear body 1, and a plurality of teeth 3 located outside the gear body 1. Oil injection holes 4 for injecting lubricating oil are provided at both the upper and lower ends of the mounting seat 2. A plurality of first oil delivery pipes 5 are provided at the lower end of the oil injection holes 4. The first oil delivery pipes 5 extend into the gear body 1 and extend out the second oil delivery pipes 6 in the direction of the teeth 3. An oil outlet hole 7 is provided at the connection between the second oil delivery pipes 6 and the sides of the teeth 3. An oil storage cavity 8 for storing lubricating oil is provided at the junction of the first oil delivery pipes 5 and the second oil delivery pipes 6.

[0014] A first slope 9 for facilitating the flow of lubricating oil into the oil storage cavity 8 is provided at the connection between the oil storage cavity 8 and the first oil delivery pipes 5. A second slope 10 for assisting the flow of lubricating oil to the second oil delivery pipes 6 is provided at the connection between the oil storage cavity 8 and the second oil delivery pipes 6.

[0015] When in use, lubricating oil is injected into the oil injection holes 4. The lubricating oil flows through the first oil delivery pipes 5 and enters the oil storage cavity 8. During the rotation of the gear body 1, when the oil storage hole is located above, the lubricating oil cannot flow to the second oil delivery pipes 6. And since the oil storage cavity 8 is an irregular cuboid with a long bottom side and short sides, the centrifugal force generated by the rotation of the gear body 1 will throw the lubricating oil in the oil storage cavity 8 onto the second slope 10. At this time, a small amount of lubricating oil will flow through the second slope 10 into the second oil delivery pipes 6 and flow out from the oil holes. When the oil storage hole is located below, the lubricating oil naturally flows through the second slope 10 into the second oil delivery pipes 6 and flows out through the oil outlet holes 7.

[0016] Furthermore, a sealing plug 11 is provided on the oil injection holes 4. The sealing plug 11 is connected to the inner wall of the oil injection holes 4 by threads.

[0017] The specific embodiments described herein are only illustrative of the spirit of the present utility model. Those skilled in the technical field to which the present utility model belongs can 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 utility model or exceed the scope defined by the appended claims.

[0018] Although the terms 1, gear body 1; 2, mounting seat 2; 3, tooth 3; 4, oil injection hole 4; 5, first oil pipeline 5; 6, second oil pipeline 6; 7, oil outlet hole 7; 8, oil storage cavity 8; 9, first slope 9; 10, second slope 10; 11, sealing plug 11 are used more frequently in this text, it does not exclude the possibility of using other terms. The use of these terms is only for more conveniently describing and explaining the essence of the present utility model; interpreting them as any additional limitation is contrary to the spirit of the present utility model.
