Description

Technical Field

[0001] This utility model relates to the field of gear technology, and in particular to a structure with a built-in oil-proof ring. Background Technology

[0002] A gear is a mechanical component that transmits motion and power through continuous meshing of gears on its rim. Gears have been used in transmission for a long time. In the late 19th century, the principle of generating gear cutting and the emergence of specialized machine tools and cutting tools based on this principle led to increased attention to the smoothness of gear operation as production developed. During high-speed operation, gears require the application of high-temperature, friction-resistant lubricating grease to their teeth to ensure normal operation and prevent wear and tooth breakage. However, the lubricating oil cannot be cleaned during gear rotation, resulting in contamination. Therefore, a gear structure with a built-in oil-proof ring was developed.

[0003] However, existing gear structures with built-in oil-proof rings have the following problems:

[0004] 1. The connecting shaft of the gear structure protrudes for a long time and is easily damaged accidentally when not in use;

[0005] 2. In the gear structure, the motor is connected to the gear shaft, which generates heat during operation. High temperature affects the life of the gear shaft.

[0006] In summary, a gear structure with a retractable connecting shaft and a self-cooling mechanism, featuring an integrated oil-proof ring, is needed.

[0007] Chinese Patent Application No. 202022767223.4: This utility model discloses a gear structure with a built-in oil-proof ring, including a gear body, an oil-proof ring fixedly connected to one side of the gear body, a meshing part fixedly connected to the outer surface of the gear body, a liquid storage cavity provided inside the gear body, a lubricating oil provided inside the liquid storage cavity, and a liquid outlet channel fixedly connected to the outer surface of the liquid storage cavity; In this utility model, by setting up a liquid storage cavity, a liquid outlet channel, and a liquid outlet hole, when the gear is working, the lubricating oil inside the liquid storage cavity is subjected to the centrifugal force of the gear rotation and flows out from multiple liquid outlet channels connected to the liquid storage cavity, and finally flows to the meshing part of the gear through the liquid outlet hole. During the continuous rotation of the gear, the lubricating oil completely covers the meshing part of the gear.

[0008] This application's design achieves the function of automatically applying lubricating oil, avoiding the trouble of manual application. During use, lubricating oil only needs to be added to the reservoir periodically. However, it cannot achieve cooling and does not have a connecting gear shaft. Utility Model Content

[0009] The technical problem to be solved by this utility model is that the connecting shaft of a gear structure with a built-in oil-proof ring protrudes for a long time, is easily damaged accidentally when not in use, and cannot cool down the gear shaft.

[0010] To address the aforementioned technical problems, a gear structure with a built-in oil-proof ring is proposed; this is achieved through the following technical solution:

[0011] The gear includes a gear body, tooth tips, and a connecting shaft. It also includes an adjustment structure for adjusting the length of the connecting shaft, an impact-resistant plate, a cooling structure, an oil-proof ring structure, and a lubrication structure. The tooth tips are located on the outer ring of the gear body. One side of the gear body has an installation groove. The lubrication structure and the length adjustment structure are installed inside the installation groove. The lubrication structure connects to the tooth tips to lubricate them. The length adjustment structure connects to the connecting shaft. The impact-resistant plate is connected to the opening of the installation groove. The other side of the gear body is connected to the oil-proof ring structure and the cooling structure. The cooling structure passes through the gear body to cool the connecting shaft.

[0012] An impact-resistant plate is installed on the surface of the mounting slot to increase the impact resistance of the gear structure during use. When the gear structure is not in use, the connecting shaft retracts into the adjustment structure to prevent it from protruding for a long time and being damaged due to accidents. When the gear structure needs to be used, the adjustment structure is controlled, the connecting shaft pops out of the adjustment structure and is then fixed, allowing the connecting shaft to extend. After that, the impact-resistant plate is installed. The lubricating oil in the lubrication structure follows the rotation of the gear to lubricate the tooth tips. Excess lubricating oil follows the rotation of the gear structure into the oil-proof ring structure. When the connecting shaft is connected to the motor and drives the gear structure to rotate, the cooling structure passes through the gear body to cool the connecting shaft.

[0013] In a preferred embodiment of the present invention, the lubrication structure includes a lubricating oil tank and a lubrication hole. The lubricating oil tank is installed in the mounting groove on one side close to the tooth tip. Multiple oil outlets are provided on the surface of the lubricating oil tank that is close to the mounting groove. A lubrication hole is provided through the tooth tip and communicates with the oil outlet of the lubricating oil tank. The lubricating oil tank is provided with a filling port and a sealing cap. Lubricating oil is added to the lubricating oil tank through the filling port. The lubricating oil in the lubricating oil tank is thrown out from the lubrication hole as the gear structure rotates to lubricate the tooth tip.

[0014] In a preferred embodiment of the present invention, the adjusting structure includes an adjusting tube, an adjusting groove, a limiting block, and a limiting structure. The adjusting tube is installed in the mounting groove, and the adjusting groove is provided inside the adjusting tube for mounting the limiting block and the connecting shaft. The connecting shaft is connected to the limiting block, and the limiting structure passes through the adjusting tube and connects to the limiting block and the connecting shaft. The connecting shaft retracts into the adjusting groove, and the adjusting tube provides protection for the connecting shaft. When needed, the limiting structure is removed, the connecting shaft pops out, and then the limiting structure is fixed.

[0015] In a preferred embodiment of the present invention, the limiting structure includes a first adjusting hole, a second adjusting hole, a third adjusting hole, a fourth adjusting hole, and a fixing screw. A set of first adjusting holes is provided on the connecting shaft, a set of second adjusting holes is provided on the limiting block, and a set of third adjusting holes and a set of fourth adjusting holes are provided on the side wall of the adjusting tube to cooperate with the first and second adjusting holes. When the first and third adjusting holes, and the second and fourth adjusting holes are respectively connected by fixing screws, the connecting shaft retracts into the adjusting tube. When the second and third adjusting holes are connected by fixing screws, the connecting shaft extends out of the adjusting tube. The different adjusting holes are fixed by fixing screws, thereby adjusting the protruding length of the connecting shaft.

[0016] In a preferred embodiment of the present invention, a spring-loaded structure is provided between the limiting block and the bottom surface of the adjusting groove to push the limiting block. When the limiting structure is opened, the spring-loaded structure pushes the limiting block upward, thereby causing the connecting shaft to extend.

[0017] In a preferred embodiment of the present invention, the spring-loaded structure includes a spring and a telescopic rod. The telescopic rod, which is wound around the spring, is connected together with the spring between the bottom surface of the adjusting groove and the limiting block. The diameter of the limiting block is smaller than the diameter of the opening of the adjusting pipe. When the limiting structure is opened, the spring extends and pushes the limiting block out.

[0018] In a preferred embodiment of the present invention, the cooling structure includes a water storage tank, a water supply pipe, a rotating micro-nozzle, and a spray outlet. The water storage tank is installed on the surface of the gear body where the connecting shaft is not mounted. Four pipe grooves are evenly arranged on the surface of the gear body. Multiple spray outlets are evenly arranged in the pipe grooves. The spray outlets connect to the mounting groove and the adjusting groove and pass through the limiting block. The water supply pipe is installed in the pipe groove, and the rotating micro-nozzle is evenly connected to the water supply pipe. The rotating micro-nozzle for cooling the connecting shaft is installed in the spray outlet. The water storage tank supplies water to the rotating micro-nozzle through the water supply pipe. The rotating micro-nozzle sprays cooling water from the spray outlet into the adjusting groove and the mounting groove to cool the connecting shaft and the gear.

[0019] In a preferred embodiment of the present invention, the oil-proof ring structure includes an oil-proof ring body, an oil receiving groove, and an oil drain port. The oil-proof ring body is connected to the side of the gear body that is not connected to the connecting shaft. An oil receiving groove is provided on the side of the oil-proof ring body that is connected to the gear body. An oil drain port is provided on the side of the oil-proof ring body. A sealing plug is provided on the oil drain port. The lubricating oil leaking from the tooth tip is thrown into the oil receiving groove as the gear structure rotates.

[0020] The advantages of this utility model compared with the prior art are:

[0021] 1. When the gear structure is not used, the connecting shaft is retracted inside the adjustment structure to prevent the connecting shaft from protruding outside for a long time and being damaged due to accidents. When the gear structure is required, adjust the adjustment structure, and the connecting shaft will pop out of the adjustment structure and then be fixed to allow the connecting shaft to extend.

[0022] 2. No manual setting of the lifeline body length is required, nor is manual tightening of the lifeline body required during installation. Simply wrap a portion of the lifeline body around the length adjustment structure. After installation, the length adjustment structure will activate, allowing the excessively long lifeline body to be wound around the length adjustment structure and tightened.

[0023] 3. First, fix both ends of the lifeline body by fixing the fixed structure. Then, by wrapping both ends of the lifeline body around the length adjustment structure, the tension and contraction of the lifeline body are controlled by the motor to make the lifeline body more stable and thus make the lifeline body stable when installed on the roof.

[0024] 4. The height adjustment structure allows the lifeline body to be set at a suitable installation height according to the roof conditions. Attached Figure Description

[0035] The following will refer to the appendix in the embodiments of this utility model. Figures 1-9 The technical solutions in the embodiments of this utility model will be described in detail below. Example

[0036] like Figures 1-9 As shown, a gear structure with a built-in oil-proof ring includes a gear body 1, a tooth tip 2, and a connecting shaft 3. It also includes an adjustment structure 4 for adjusting the length of the connecting shaft 3, an impact-resistant plate 5, a cooling structure 6, an oil-proof ring structure 7, and a lubrication structure 8.

[0037] The outer ring of the gear body 1 is welded with tooth tips 2. The middle position of the gear body 1 is connected to the connecting shaft 3 through the adjustment structure 4. The tooth tips 2 are used to mesh with other gears. The connecting shaft 3 is connected to the drive motor shaft by screws and connecting keys. The drive motor drives the connecting shaft 3 to rotate, which in turn drives the gear body 1 and tooth tips 2 to rotate.

[0038] The adjusting structure 4 is installed in the middle position of the gear body 1. The adjusting structure 4 is connected to the connecting shaft 3. The installation position of the connecting shaft 3 in the adjusting structure 4 is adjusted, thereby adjusting the length of the connecting shaft 3 extending out.

[0039] A circular mounting groove 9 is provided on the circular surface of the gear body 1. When in use, an impact-resistant plate 5 is fixedly connected to the surface of the mounting groove 9 to ensure the stability of the gear structure during use.

[0040] The lubrication structure 8 is installed in the mounting groove 9 on the surface of the gear body 1, and is close to the side wall of the mounting groove 9. The lubricating oil of the lubrication structure 8 passes through the gear body 1 to lubricate the tooth tip 2.

[0041] The oil-proof ring structure 7 and the cooling structure 6 are installed on another circular surface of the gear body 1. The cooling structure 6 passes through the gear body 1 and sprays coolant onto the connecting shaft 3 to cool the gear structure when it rotates.

[0042] The diameter of the oil-proof ring structure 7 is larger than that of the gear structure, ensuring that the lubricating oil thrown out of the gear structure can be thrown into the oil-proof ring structure 7, and with the action of centrifugal force, the lubricating oil will be thrown back from the oil-proof ring structure 7 onto the gear structure.

[0043] The lubrication structure 8 includes a lubricating oil tank 81 and lubrication holes 82. The lubricating oil tank 81 is a ring-shaped box. The lubricating oil tank 81 is welded into the mounting groove 9 on the surface of the gear body 1, and the outer side of the lubricating oil tank 81 is in close contact with the inner side of the mounting groove 9. Multiple oil outlets are evenly arranged on the outer side of the lubricating oil tank 81. Multiple lubrication holes 82 corresponding to the oil outlets are provided on the tooth tip 2. The lubrication holes 82 penetrate the tooth tip 2 and communicate with the oil outlets.

[0044] The lubricating oil in the lubricating oil tank 81 is thrown out from the oil outlet into the lubrication hole 82 due to the centrifugal force of the gear structure rotation, and lubricates the tooth tip 2 at the tooth tip 2.

[0045] The lubricating oil tank 81 is provided with a filling port 83, through which lubricating oil is added to the lubricating oil tank 81 to ensure that the lubrication structure 8 can be used normally. The filling port 83 is provided with a sealing cap 84 to ensure the airtightness of the lubricating oil tank 81.

[0046] The adjustment structure 4 includes an adjustment pipe 41, an adjustment groove 42, a limiting block 43, and a limiting structure 44. The adjustment pipe 41 is welded to the middle position of the mounting groove 9. The adjustment groove 42 is provided inside the adjustment pipe 41. The limiting block 43 is installed in the adjustment groove 42. A connecting shaft 3 is welded to the limiting block 43. The connecting shaft 3 passes through the upper opening of the adjustment pipe 41. The diameter of the upper opening of the adjustment pipe 41 is smaller than the diameter of the limiting block 43. The limiting structure 44 passes through the adjustment pipe 41 and connects the limiting block 43 and the connecting shaft 3, fixing the position of the limiting block 43 and the connecting shaft 3 in the adjustment groove 42.

[0047] The limiting structure 44 includes a first adjusting hole 441, a second adjusting hole 442, a third adjusting hole 443, a fourth adjusting hole 444, and a fixing screw 445. A set of first adjusting holes 441 is provided on the connecting shaft 3, a set of second adjusting holes 442 is provided on the limiting block 43, and a set of vertical third adjusting holes 443 and a set of fourth adjusting holes 444 are provided on the side wall of the adjusting tube 41. The third adjusting holes 443 and the fourth adjusting holes 444 are used in conjunction with the first adjusting holes 441 and the second adjusting holes 442.

[0048] In this embodiment, there are four adjustment holes in a set: the first adjustment hole 441, the second adjustment hole 442, the third adjustment hole 443, and the fourth adjustment hole 444. Each set of adjustment holes is fixed with four fixing screws 445 to ensure the stability of the connecting shaft connection.

[0049] When the connecting shaft 3 is not in use, the first adjusting hole 441 and the third adjusting hole 443 correspond to each other, the second adjusting hole 442 and the fourth adjusting hole 444 correspond to each other, and are connected by fixing screws 445 respectively. At this time, the connecting shaft 3 is retracted into the adjusting groove 42.

[0050] When the connecting shaft 3 is needed, remove the fixing screw 445, pull the connecting shaft 3 out of the adjustment groove 42 so that the second adjustment hole 442 corresponds to the third adjustment hole 443, and then connect the limiting plate and the adjustment tube 41 through the fixing screw 445.

[0051] The extension and retraction of the connecting shaft 3 are achieved by fixing it with screws 445 to the corresponding adjustment holes.

[0052] A spring structure 45 is welded between the limiting block 43 and the bottom surface of the adjusting groove 42 to push the limiting block 43. When the limiting structure 44 is opened, the spring structure 45 pushes the limiting block 43 upward, causing the connecting shaft 3 to extend.

[0053] The spring-loaded structure 45 includes a spring 451 and a telescopic rod 452. The spring 451 is wound around the telescopic rod 452. The upper ends of the spring 451 and the telescopic rod 452 are welded to the lower surface of the limiting block 43, and the lower ends of the spring 451 and the telescopic rod 452 are welded to the bottom of the adjusting groove 42. When the fixing screw 445 is removed, the spring 451 pushes the limiting block 43 to move upward, pushing the connecting shaft 3 toward the upper opening of the adjusting groove 42, so that the connecting shaft 3 extends. The telescopic rod 452 restricts the horizontal position of the limiting block 43, preventing the limiting block 43 from being horizontally displaced when pushed by the spring 451.

[0054] The other side of the gear body 1 is connected to a cooling structure 6, which includes a water tank 61, a water supply pipe 62, a rotating micro-nozzle 63, and a spray outlet 64. The water tank 61 is welded to the surface of the gear body 1 that is not connected to the connecting shaft 3. Four pipe grooves 65 are provided on the mounting surface of the gear body 1. Multiple spray outlets 64 are evenly arranged inside the pipe grooves 65. The spray outlets 64 are connected to the mounting groove 9 and the adjustment groove 42. The spray outlets 64 in the adjustment groove 42 pass through the limiting block 43.

[0055] A water supply pipe 62 is welded inside the pipe trough 65. Multiple rotating micro-nozzles 63 are welded on the water supply pipe 62 at the position corresponding to the spray outlet 64. Cooling water enters the water supply pipe 62 from the water storage tank 61 and is sprayed out from the spray outlet 64 through the rotating micro-nozzles 63 to the regulating trough 42 and the mounting trough 9 to cool the connecting rod.

[0056] The oil-proof ring structure 7 includes an oil-proof ring body 71, an oil receiving groove 72, and an oil drain port 73. The oil-proof ring body 71 is annular and is welded to the side of the gear body 1 where the cooling structure 6 is installed. The diameter of the outer ring of the oil-proof ring is larger than the diameter of the entire gear structure, ensuring that the lubricating oil on the tooth tip 2 can be thrown into the oil receiving groove 72 by centrifugal force.

[0057] An oil receiving groove 72 is provided on the side of the oil-proof ring body 71 near the tooth tip 2, and an oil drain port 73 is provided on the outer curved surface of the oil-proof ring body 71. Lubricating oil enters the oil-proof ring body 71 from the oil receiving groove 72, reducing the possibility of lubricating oil being thrown out of the gear structure. A sealing plug 74 is provided on the oil drain port 73 to prevent the lubricating oil inside the oil-proof ring body 71 from flying out of the oil drain port 73 when rotating.

[0058] The working process of this embodiment:

[0059] The impact-resistant plate 5 is installed on the surface of the mounting groove 9 to increase the impact resistance of the gear structure during use. When the gear structure is not in use, the connecting shaft 3 is retracted inside the adjusting structure 4 to prevent the connecting shaft 3 from protruding outside for a long time and being damaged due to accidents. When the gear structure needs to be used, the adjusting structure 4 is controlled, the connecting shaft 3 pops out of the adjusting structure 4 and is then fixed. After the connecting shaft 3 is extended, the impact-resistant plate 5 is installed. The lubricating oil of the lubrication structure 8 follows the rotation of the gear to lubricate the tooth tip 2. Excess lubricating oil follows the rotation of the gear structure into the oil-proof ring structure 7. When the connecting shaft 3 is connected to the motor and drives the gear structure to rotate, the cooling structure 6 passes through the gear body 1 to cool the connecting shaft 3.

[0060] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
