Self-lubricating bevel gear

Abstract

The utility model discloses a self-lubricating bevel gear, which relates to the technical field of self-lubricating bevel gears and comprises a first bevel gear and a second bevel gear, and one side of the first bevel gear is meshed with the second bevel gear. According to the utility model, the umbrella-shaped gear is lubricated by the lubricating liquid flowing out of the pipe body, and the lubricating liquid in the connecting rod flows onto the umbrella-shaped gear through the pipe body to lubricate the umbrella-shaped gear in order to prevent the existing bevel gear from being lubricated only by externally adding lubricating oil and from being unable to be self-lubricated. In order to prevent the situation that holes are formed in the bevel gear for self-lubrication, the situation that the strength of the bevel gear is reduced due to local stress concentration on the bevel gear is avoided, the pipe body is used for bearing lubricating liquid, the situation that small holes for oil outlet are prone to being blocked is avoided, and it is guaranteed that nearby gear teeth can be well lubricated; and the two connecting rods are fixed by using the bolts, so that the operation is very stable.

Description

Technical Field

[0001] The utility model relates to the technical field of self-lubricating bevel gears, and particularly relates to a self-lubricating bevel gear. Background Art

[0002] Bevel gears, that is, conical gears, are used for transmission between intersecting shafts, and are divided into straight bevel gears and spiral bevel gears. The transmission of helical bevel gears runs smoothly, and the gear has a relatively high bearing capacity, but it is difficult to manufacture and is less used. Curved-tooth bevel gears have the characteristics of smooth transmission, low noise and large bearing capacity.

[0003] The current bevel gears can only be lubricated by adding lubricating oil externally and cannot perform self-lubrication. Moreover, self-lubrication requires drilling holes in the bevel gears, which will cause local stress concentration on the bevel gears, thereby reducing the strength of the bevel gears. In addition, the small oil outlet holes are easily blocked, resulting in poor lubrication of the teeth near them. Summary of the Invention

[0004] In view of the problems existing in the current self-lubricating bevel gears, the present utility model is proposed.

[0005] Therefore, the purpose of the present utility model is to provide a self-lubricating bevel gear, which solves the problem of inability to perform self-lubrication.

[0006] In order to achieve the above purpose, the present utility model provides the following technical solutions:

[0007] A self-lubricating bevel gear includes a first bevel gear and a second bevel gear. A second bevel gear is meshed on one side of the first bevel gear. Fixed rods are fixedly arranged at one ends of the first bevel gear and the second bevel gear. Fixed seats are rotatably arranged on the rod walls of the fixed rods. A connecting rod is fixedly arranged on one side of each fixed seat. A groove body is fixedly opened in one of the connecting rods. A liquid replenishing port is fixedly arranged at the top of the groove body. A fixed plug is slidably arranged in the liquid replenishing port. A pipe body is fixedly rotatably arranged at the bottom of the groove body.

[0008] Preferably, a threaded seat is fixedly arranged at the top of one of the connecting rods. A bolt is threadedly arranged in the threaded seat. The two connecting rods are fixed by the bolt.

[0009] Preferably, a first sealing gasket is fixedly arranged in the liquid replenishing port. A second sealing gasket is fixedly arranged on the outer side wall of the fixed plug.

[0010] Preferably, a rotating seat is fixedly arranged at the bottom of one of the connecting rods. The rotating seat is rotatably connected to the pipe body.

[0011] Furthermore, a sponge pad is fixedly arranged at one end of the second bevel gear.

[0012] Preferably, both the first gasket and the second gasket are made of silicone gaskets.

[0013] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0014] In the present utility model, the lubricating fluid flowing out of the pipe body is used to lubricate the bevel gear. In order to prevent the current bevel gear from only being lubricated by externally adding lubricating oil and avoid being unable to perform self-lubrication, the lubricating fluid in the connecting rod is used to flow the lubricating fluid to the bevel gear through the pipe body for lubrication. In order to prevent self-lubrication from requiring holes to be drilled in the bevel gear and avoid causing local stress concentration on the bevel gear and reducing the strength of the bevel gear, the pipe body is used to carry the lubricating fluid to avoid the small oil outlet holes being easily blocked and ensure that the nearby teeth can be better lubricated. And in order to make the rotation between the gears more stable, bolts are used to fix the two connecting rods, which is very stable. BRIEF DESCRIPTION OF THE DRAWINGS
