[0001] The utility model relates to the technical field of sprockets, in particular to a high-efficiency meshing sprocket for motorcycles which can be automatically oiled. Background Art

[0002] Motorcycle, a two-wheeled or three-wheeled vehicle driven by a gasoline engine and steered by a handlebar, is light, flexible, and fast, and is widely used for patrolling, passenger and freight transportation, etc., and is also used as sports equipment. Sprocket is a wheel with cog-type sprocket teeth, which is used to mesh with the block with accurate pitch on the link chain or cable. Sprocket is widely used in mechanical transmission in chemical industry, textile machinery, escalator, wood processing, stereo parking garage, agricultural machinery, food processing, instrumentation, petroleum and other industries;

[0003] During the use of motorcycle sprockets, the sprocket and the chain will inevitably come into contact with dust and gravel. A small amount of dust and gravel will stick to them and be brought to the contact point between the sprocket and the chain. During the friction process, the contact point between the sprocket and the chain will be worn. Therefore, it is necessary to add lubricating oil to the sprocket in time. However, it is not convenient to apply lubricating oil to the contact point between the sprocket and the chain, which reduces the effect of the lubricating oil. At the same time, when the sprocket is in use, the stability of the docking structure such as the chain cannot be guaranteed during transmission, so there is a possibility of falling off. In view of the above problems, the inventor proposes a motorcycle high-efficiency meshing sprocket that can be automatically oiled to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example: Figure 1-4 As shown, the utility model provides a technical solution: a motorcycle high-efficiency meshing sprocket capable of automatic oiling, comprising a sprocket body 1, an outer ring of the sprocket body 1 is provided with evenly distributed arc grooves 16, an inner cavity 11 is provided inside the sprocket body 1, and the outer ring of the sprocket body 1 is provided with liquid outlets 13 at the arc grooves 16, an annular mounting frame 2 is symmetrically and detachably connected at the center of both side ends of the sprocket body 1, the outer ring of the annular mounting frame 2 is fixedly connected with three sliding grooves 3, and the three sliding grooves 3 are evenly distributed, and a limit plate 31 is slidably inserted inside the end of the sliding groove 3 away from the annular mounting frame 2.

[0020] A filter plate 14 is disposed inside the liquid outlet 13 .

[0021] By adopting the above technical solution, a filter plate 14 is provided inside the liquid outlet 13 to prevent dust or sand from entering the inner cavity 11 when the sprocket body 1 rotates.

[0022] A liquid filling port 12 is provided at a side end of the sprocket body 1 near the outer ring, and a blocking block 15 is provided inside the liquid filling port 12 .

[0023] By adopting the above technical solution, the liquid filling port 12 is provided in order to fill the lubricating oil into the inner cavity 11 .

[0024] An L-plate 32 is fixedly connected to the side end of the sliding groove 3 near the top, a clamping shaft 33 is slidably inserted at the center of the L-plate 32, and a support plate 34 is fixedly connected to the end of the clamping shaft 33 away from the limiting plate 31.

[0025] By adopting the above technical solution, the L plate 32 is provided to slide and insert the clamping shaft 33 , so as to achieve the limiting work of the limiting plate 31 .

[0026] One end of the limiting plate 31 close to the L plate 32 is provided with evenly distributed clamping grooves 37 , and the clamping grooves 37 are matched with the clamping shaft 33 .

[0027] By adopting the above technical solution, the clamping groove 37 is provided to cooperate with the clamping shaft 33 to achieve the limiting work of the limiting plate 31.

[0028] A spring 36 is fixedly connected to the side end of the support plate 34 , and the other end of the spring 36 is fixedly connected to the L plate 32 . The spring 36 is sleeved on the outer ring of the clamping shaft 33 , and a pull block 35 is fixedly connected to one end of the support plate 34 away from the spring 36 .

[0029] By adopting the above technical solution, the spring 36 is provided to cooperate with the support plate 34 to realize the reset work of the clamping shaft 33.

[0030] Working principle: When the device is in use, when it is necessary to apply lubricating oil to the contact point between the sprocket body 1 and the chain, the lubricating oil is added into the inner cavity 11 through the liquid filling port 12, and then the lubricating oil is prevented from flowing out from the liquid filling port 12 under the action of the blocking block 15. When the sprocket body 1 is rotating at work, the lubricating oil can be sprayed out through the liquid outlet 13 under the action of the filter plate 14, thereby achieving the effect of applying the lubricating oil to the contact point between the sprocket body 1 and the chain, thereby solving the problem of inconvenience in applying the lubricating oil to the contact point between the sprocket and the chain, which reduces the effect of using the lubricating oil.

[0031] When it is necessary to protect chains of different types, the pulling block 35 is pulled away from the limiting plate 31, so that the fixedly connected support plate 34 drives the clamping shaft 33 to move to one side, thereby releasing the limiting work on the limiting plate 31. Then, the sliding limiting plate 31 is moved to the appropriate position, and the force on the pulling block 35 can be released. Then, under the action of the spring 36, the clamping shaft 33 drives the support plate 34 to be clamped in the clamping groove 37. At this time, the limiting work on the limiting plate 31 can be completed, thereby solving the problem that when the sprocket is in use, the sprocket cannot ensure the stability of the docking structure such as the chain during transmission, and at the same time preventing the possibility of the chain detaching from the sprocket body 1.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
