Description

Technical Field

[0001] This utility model relates to the field of gears, and more specifically, to a straight bevel gear. Background Technology

[0002] Straight bevel gears are a type of bevel gear. Their teeth are distributed on a truncated cone, and the tooth profile gradually decreases from the large end to the small end. The extension lines of the teeth intersect the cone apex at a single point.

[0003] During the rotation of bevel gears, there is friction between the tooth surfaces. By applying lubricating oil to the tooth surfaces, an oil film can be formed. The oil film can reduce the coefficient of friction on the gear surface, thereby making the transmission between gears smoother and reducing gear wear. Currently, lubricating oil is often directly applied to the gear teeth. However, some gears have a large number of teeth, and the lubricating oil needs to cover both sides of the tooth surfaces and embed itself in the gaps between the two teeth. It is difficult to achieve this during manual application.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a straight bevel gear.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a straight bevel gear, comprising a gear body and a rotating shaft, wherein the gear body is provided with a plurality of teeth, and an oil storage cavity is provided in both the gear body and the rotating shaft, wherein the gear body is provided with a plurality of oil outlet holes located between two adjacent teeth, a blocking member is rotatably connected in the oil storage cavity, the blocking member abuts against the inner wall of the oil storage cavity where the oil outlet holes are provided, and a plurality of through holes communicating with the oil outlet holes are provided in the blocking member, an oil injection hole is provided on the outer peripheral wall of the rotating shaft, and an oil pusher ring is slidably connected in the oil storage cavity, the oil pusher ring is always located in the rotating shaft, and the oil pusher ring can slide toward the gear body.

[0007] The present invention is further configured such that: an arc-shaped groove is provided on the side of the gear body facing away from the teeth, and a toggle block located in the arc-shaped groove is fixedly connected to the barrier, and a limit member is provided on the toggle block, the limit member being able to restrict relative rotation between the gear body and the barrier.

[0008] The present invention is further configured such that: the limiting member is a wing bolt threaded onto the actuating block; the gear body is provided with a threaded hole one and a threaded hole two; when the limiting member is threaded into the threaded hole one, all the through holes are connected to the oil outlet hole; when the limiting member is threaded into the threaded hole two, all the through holes are misaligned with the oil outlet hole.

[0009] The present invention is further configured such that: a sliding groove is provided on the inner wall of the oil storage cavity facing away from the gear body, the sliding groove is connected to the outer wall of the rotating shaft, a push rod located in the sliding groove is fixedly connected to one side of the oil pusher ring, and elastic pads are fixedly connected to both the outer and inner peripheral walls of the oil pusher ring.

[0010] The present invention is further configured such that: a push block is fixedly connected to the push rod, one side of the push block is flush with the outer wall of the rotating shaft, and the push block always has a gap with the front and rear side walls of the slide groove.

[0011] The present invention is further configured such that: the inner peripheral wall of the oil injection hole is provided with an internal thread, the internal thread of the oil injection hole is connected to a sealing post, and the outer peripheral wall of the sealing post is provided with an external thread.

[0012] In summary, this utility model has the following beneficial effects:

[0013] By rotating the blocking component, the oil outlet and the perforation are connected. Then, the oil pusher ring is pushed, causing the lubricating oil in the oil reservoir to be pushed out from the oil outlet. The oil outlet is located between two adjacent teeth, ensuring that lubricating oil flows out from the gaps between all teeth. After sufficient lubricating oil is available, the blocking component is rotated back, causing the perforation of the blocking component to be misaligned with the oil outlet, thus preventing the lubricating oil from flowing out. At this time, the gear body is slowly driven to rotate, causing the lubricating oil between the two teeth to spread out and be evenly distributed on the tooth surfaces on both sides of the teeth. Through the above settings, the lubricating oil can be evenly distributed between each tooth, preventing leakage, and the amount of lubricating oil between each pair of teeth is the same, ensuring the lubrication effect.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] A type of straight bevel gear, such as Figure 1 , Figure 2 and Figure 3 As shown, the device includes a gear body 1 and a rotating shaft 2. One end of the gear body 1 and the rotating shaft 2 are fixedly connected. The gear body 1 has several teeth 3. An oil storage chamber 4 is shared within both the gear body 1 and the rotating shaft 2. Several oil outlet holes 5 are located between adjacent teeth 3 on the gear body 1. An oil outlet hole 5 exists between any two adjacent teeth 3. A blocking component 6 is rotatably connected within the oil storage chamber 4. The shape of the blocking component 6 is the same as the shape of the oil storage chamber 4 within the gear body 1. The blocking component 6 abuts against the inner wall of the oil storage chamber 4 where the oil outlet holes 5 are located. Several through holes 7 are provided on the blocking component 6 that can communicate with the oil outlet holes 5. An oil filling hole 8 is provided on the outer peripheral wall of the rotating shaft 2. An oil pusher ring 9 is slidably connected within the oil storage chamber 4. The oil pusher ring 9 is always located within the rotating shaft 2 and can slide towards the gear body 1. The gear body 1 is installed via the rotating shaft 2. Before installation, the oil storage chamber 4 is filled with lubricating oil. When the teeth 3 on the gear body 1 need lubrication, first rotate the blocking member 6 so that the perforation 7 on the blocking member 6 is aligned with the oil outlet 5. Because the lubricating oil itself has poor fluidity and the diameter of the oil outlet 5 is relatively small, the lubricating oil does not easily flow out. Then push the oil pusher ring 9 so that the lubricating oil in the oil storage chamber 4 is pushed out from the oil outlet 5. The oil outlet 5 is located between two adjacent teeth 3, so that lubricating oil flows out from the gaps between all teeth 3. After there is enough lubricating oil, rotate the blocking member 6 so that the perforation 7 on the blocking member 6 is misaligned with the oil outlet 5, so that the lubricating oil will not flow out. At this time, slowly drive the gear body 1 to rotate so that the lubricating oil between the two teeth 3 is dispersed and evenly distributed on the tooth surface on both sides of the teeth 3. Through the above settings, the lubricating oil can be evenly distributed between each tooth 3 to prevent leakage, and the amount of lubricating oil between each pair of teeth 3 is the same to ensure the lubrication effect.

[0021] like Figure 2 , Figure 3 and Figure 4As shown, an arc-shaped groove 10 is formed on the side of the gear body 1 facing away from the teeth 3. The arc-shaped groove 10 communicates with the oil storage chamber 4. A moving block 11 located in the arc-shaped groove 10 is fixedly connected to the barrier 6. A limiting member 12 is provided on the moving block 11. The limiting member 12 can restrict the relative rotation between the gear body 1 and the barrier 6. The rotation of the barrier 6 can be controlled by moving the moving block 11 located in the arc-shaped groove 10. The limiting member 12 is a wing bolt threaded onto the moving block 11. The gear body 1 is provided with a threaded hole one and a threaded hole two. When the limiting member 12... When the threaded connection is in the first threaded hole, all the through holes 7 are connected to the oil outlet hole 5. When the limiting member 12 is threaded in the second threaded hole, all the through holes 7 are misaligned with the oil outlet hole 5. By threading the disc bolt into the second threaded hole, the stability between the blocking member 6 and the gear body 1 is ensured, the limiting effect of the blocking member 6 is guaranteed, and the threaded connection is relatively firm, so that the blocking member 6 and the gear body 1 are not easy to slide relative to each other during rotation. Furthermore, the settings of the first and second threaded holes provide feedback for people to turn the toggle block 11, which is convenient for people to operate.

[0022] like Figure 3 and Figure 4 As shown, a groove 13 is provided on the inner wall of the oil storage chamber 4 facing away from the gear body 1. The groove 13 is connected to the outer wall of the rotating shaft 2. A push rod 14 located in the groove 13 is fixedly connected to one side of the push ring 9. Elastic pads 15 are fixedly connected to both the outer and inner peripheral walls of the push ring 9. The elastic pads 15 are made of rubber. By pushing the push rod 14 in the groove 13, the movement of the push ring 9 can be controlled. The setting of the elastic pads 15 makes it difficult for lubricating oil to flow through the outer peripheral wall of the push ring 9. No air seal structure is added between the barrier 6 and the inner wall of the gear body 1, so that when adding lubricating oil, the air inside the oil storage chamber 4 can flow into the misaligned oil outlet 5 through the perforation 7 and be discharged. The lubricating oil is blocked by gravity and surface tension. The lubricating oil cannot pass through the oil reservoir 4. A push block 16 is fixedly connected to the push rod 14. One side of the push block 16 is flush with the outer wall of the rotating shaft 2. The push block 16 always has a gap with the front and rear side walls of the slide groove 13. People can control the forward and backward movement of the push rod 14 by pushing the push block 16 back and forth. The inner peripheral wall of the oil injection hole 8 is provided with internal threads. The internal thread of the oil injection hole 8 is connected to the sealing post 17. The outer peripheral wall of the sealing post 17 is provided with external threads. People add lubricating oil to the oil reservoir 4 through the oil injection hole 8. The sealing post 17 is threaded in the oil injection hole 8, so that the lubricating oil is not easy to flow out of the oil injection hole 8. The gear body 1 and the rotating shaft 2 are both made of carbon steel, which ensures the strength of the gear body 1 and the rotating shaft 2.
