Description

Technical Field

[0001] This utility model relates to the field of lubrication technology for speed reducers, specifically to a lubrication nozzle mounting structure for the worm gear of a speed reducer. Background Technology

[0002] Speed ​​reducers are core components in mechanical transmission systems. Their primary function is to convert high-speed, low-torque input from power sources such as motors into low-speed, high-torque output through internal meshing transmission mechanisms (such as gears, worm gears, etc.), or to achieve speed-increasing transmission according to operating conditions, thereby meeting the speed and torque requirements of various mechanical equipment. Among them, worm gear reducers, with their unique advantages such as compact structure, large transmission ratio, smooth operation, low noise, and ability to achieve interleaved shaft transmission, are widely used in many fields such as industrial automated production lines, construction machinery, mining machinery, transportation equipment, medical devices, precision instruments, and refrigeration machines, and are an important basic component to ensure the stable operation of equipment.

[0003] In the operation of the worm gear reducer, the meshing transmission between the worm and the worm wheel is the core component. However, this transmission method has significant technical drawbacks: the meshing surface of the worm gear is mainly based on sliding friction, and the relative sliding speed between the tooth surfaces is high (especially in high-speed transmission scenarios). This makes it easy for a large amount of frictional heat to be generated in the meshing area. At the same time, the tooth surfaces will face serious failure risks such as wear, scuffing, and pitting.

[0004] Traditional worm gear reducers typically employ oil immersion lubrication or simple oil spraying lubrication. While oil immersion lubrication is simple in structure, under high-speed or heavy-load conditions, the high-speed rotation of the worm gear generates significant oil churning resistance, increasing power consumption. Furthermore, the lubricating oil is prone to aging and deterioration at high temperatures, and it is difficult to accurately cover the entire meshing area, resulting in poor lubrication uniformity. Additionally, the nozzle body is not accurately positioned, leading to low installation efficiency. Moreover, it is difficult to quickly disassemble and maintain the nozzle body, making it impractical. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a lubrication nozzle mounting structure for the worm gear of a speed reducer, which can effectively solve the problems in the prior art.

[0006] The technical solution adopted by this utility model is: a lubrication nozzle mounting structure for a worm gear in a speed reducer, including a speed reducer gearbox, a worm body located inside the speed reducer gearbox, and a worm wheel body meshing with the worm body. A threaded sleeve is fixedly installed on the top of the speed reducer gearbox, and a connecting pipe is slidably installed on the inner side of the threaded sleeve. A nozzle body is provided on the side of the connecting pipe near the speed reducer gearbox. A limiting plate is fixedly installed on the outer surface of the nozzle body near the end of the connecting pipe. A positioning block is fixedly installed on the end of the limiting plate near the connecting pipe. A limiting groove is opened at the end of the connecting pipe near the nozzle body, and positioning grooves are opened at both ends of the limiting groove.

[0007] Preferably, the limiting groove is adapted to the nozzle body, the positioning block and the positioning groove are plugged in, and a locking screw is provided on the outside of the connecting pipe, the locking screw passing through the connecting pipe and extending into the interior of the nozzle body.

[0008] The above technical solution, with the limiting groove matching the nozzle body and the positioning block and positioning groove designed for plug-in installation, facilitates quick alignment and installation of the nozzle body and connecting pipe. The locking screw passes through the connecting pipe and extends into the interior of the nozzle body, which further improves the connection strength between the nozzle body and the connecting pipe. At the same time, the threaded connection method also facilitates quick disassembly of the nozzle body in the later stage, making it easy to replace and maintain.

[0009] Preferably, a groove is formed on the outer surface of the nozzle body near the connecting pipe, and a sealing ring is embedded in the inner side of the groove.

[0010] By using the above technical solution, the sealing effect between the nozzle body and the connecting pipe is improved and the leakage of lubricating oil is reduced by embedding the sealing ring into the groove on the outer surface of the nozzle body near the connecting pipe.

[0011] Preferably, the sealing ring is made of rubber, and there are three identical sets of sealing rings, which are distributed at equal intervals on the outer surface of the nozzle body.

[0012] The above technical solution uses rubber to make the sealing rings, which have good elasticity and sealing properties. By setting three sets of equally spaced sealing rings, the sealing performance between the nozzle body and the connecting pipe is further improved, avoiding the leakage of lubricating oil and the waste of resources.

[0013] Preferably, the cross-section of the connecting pipe is in the shape of a "<", and there are two identical sets of connecting pipes, which are symmetrically distributed on the outer surface of the worm gear body.

[0014] The above technical solution utilizes a "<" shaped cross-section for the connecting pipe. This allows the nozzle to directly spray lubricating oil onto the outer surface of the worm gear body. The meshing connection between the worm gear body and the worm shaft body ensures uniform lubrication on both surfaces. By symmetrically distributing two sets of connecting pipes on the outer surface of the worm gear body, lubricating oil can be simultaneously sprayed onto both the meshing and disengaging ends, ensuring full-cycle lubrication in the meshing area.

[0015] Preferably, an annular sleeve is rotatably mounted on the outer surface of the connecting pipe, and the annular sleeve and the threaded sleeve are threadedly connected.

[0016] The above technical solution, with its threaded connection between the annular sleeve and the threaded sleeve, facilitates quick fixing of the connecting pipe to the gearbox of the reducer without the need for external tools, thus shortening maintenance time. Furthermore, when maintenance of the nozzle body is required later, simply reverse the annular sleeve until it separates from the threaded sleeve to achieve quick disassembly and replacement of the nozzle body.

[0017] Compared with the prior art, this utility model provides a lubrication nozzle mounting structure for a speed reducer worm gear, which has the following advantages: 1. The lubrication nozzle mounting structure for the worm gear of the reducer is adapted to the nozzle body through the limiting groove, and the positioning block and positioning groove are designed for plug-in installation, which can facilitate the quick alignment and installation of the nozzle body and the connecting pipe. The locking screw passes through the connecting pipe and extends into the interior of the nozzle body, which can further improve the connection strength between the nozzle body and the connecting pipe. At the same time, the threaded connection method also facilitates the quick disassembly of the nozzle body in the later stage, making it easy to replace and maintain. 2. The lubrication nozzle mounting structure for the worm gear of the reducer is designed with a threaded connection between the annular sleeve and the threaded sleeve. This facilitates the quick fixing of the connecting pipe to the reducer gearbox without the need for external tools, thus shortening maintenance time. When the nozzle body needs maintenance in the future, simply turn the annular sleeve in the opposite direction until it separates from the threaded sleeve to achieve quick disassembly and replacement of the nozzle body. 3. The lubrication nozzle mounting structure for the worm gear of the speed reducer improves the sealing effect between the nozzle body and the connecting pipe and reduces lubricating oil leakage by embedding a sealing ring into a groove on the outer surface of the nozzle body near the connecting pipe.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: As Figure 1-7 As shown, the present invention provides a lubrication nozzle mounting structure for a worm gear in a speed reducer, including a speed reducer gearbox 1, a worm body 2 located inside the speed reducer gearbox 1, and a worm gear body 3 meshing with the worm body 2. A threaded sleeve 4 is fixedly installed on the top of the speed reducer gearbox 1, and a connecting pipe 5 is slidably installed on the inner side of the threaded sleeve 4. A nozzle body 6 is provided on the side of the connecting pipe 5 near the speed reducer gearbox 1. A limiting plate 7 is fixedly installed on the outer surface of the nozzle body 6 near the connecting pipe 5. A positioning block 8 is fixedly installed on the end of the limiting plate 7 near the connecting pipe 5. A limiting groove 11 is opened at the end of the connecting pipe 5 near the nozzle body 6, and positioning grooves 12 are opened at both ends of the limiting groove 11.

[0022] Specifically, the limiting groove 11 is adapted to the nozzle body 6, the positioning block 8 and the positioning groove 12 are plug-in installed, and a locking screw 13 is provided on the outside of the connecting pipe 5, which passes through the connecting pipe 5 and extends into the interior of the nozzle body 6. The advantages are that the adaptation of the limiting groove 11 to the nozzle body 6 and the plug-in design of the positioning block 8 and the positioning groove 12 facilitate quick alignment and installation of the nozzle body 6 and the connecting pipe 5. Furthermore, the locking screw 13, passing through the connecting pipe 5 and extending into the interior of the nozzle body 6, further enhances the connection strength between the nozzle body 6 and the connecting pipe 5. Simultaneously, the threaded connection facilitates quick disassembly of the nozzle body 6, making replacement and maintenance easier.

[0023] Specifically, a groove 9 is formed on the outer surface of the nozzle body 6 near the connecting pipe 5, and a sealing ring 10 is embedded in the inner side of the groove 9. The advantage is that by embedding the sealing ring 10 into the groove 9 on the outer surface of the nozzle body 6 near the connecting pipe 5, the sealing effect between the nozzle body 6 and the connecting pipe 5 is improved, and the leakage of lubricating oil is reduced.

[0024] Specifically, the sealing ring 10 is made of rubber, and three identical sets of sealing rings 10 are provided, evenly distributed on the outer surface of the nozzle body 6. The advantage is that by using rubber for the sealing rings 10, which has good elasticity and sealing properties, and by setting three equally spaced sets of sealing rings 10, the sealing performance between the nozzle body 6 and the connecting pipe 5 is further improved, preventing lubricant leakage and resource waste.

[0025] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0026] Specifically, the connecting pipe 5 has a "<" shaped cross-section, and two identical sets of connecting pipes 5 are symmetrically distributed on the outer surface of the worm gear body 3. The advantage is that the "<" shaped cross-section of the connecting pipes 5 facilitates the direct spraying of lubricating oil onto the outer surface of the worm gear body 3 by the nozzle body 6. Through the meshing connection between the worm gear body 3 and the worm body 2, the lubricating oil is evenly distributed on both the worm gear body 3 and the worm body 2. The symmetrical distribution of two sets of connecting pipes 5 on the outer surface of the worm gear body 3 allows for simultaneous spraying of lubricating oil to both the meshing and disengaging ends of the worm gear body 3, ensuring full-cycle lubrication in the meshing area.

[0027] Specifically, an annular sleeve 14 is rotatably mounted on the outer surface of the connecting pipe 5, and the annular sleeve 14 is threadedly connected to the threaded sleeve 4. The advantage is that the threaded connection between the annular sleeve 14 and the threaded sleeve 4 facilitates quick fixing of the connecting pipe 5 to the gearbox 1 of the reducer without the need for external tools, thus shortening maintenance time. Furthermore, when maintenance of the nozzle body 6 is required later, the nozzle body 6 can be quickly disassembled by simply twisting the annular sleeve 14 in the reverse direction until it separates from the threaded sleeve 4, facilitating rapid replacement.

[0028] Working Principle: During use, the nozzle body 6 is adapted to the limiting groove 11, and the positioning block 8 and positioning groove 12 are designed for plug-in installation, which facilitates quick alignment and installation of the nozzle body 6 and the connecting pipe 5. The locking screw 13 passes through the connecting pipe 5 and extends into the interior of the nozzle body 6, further enhancing the connection strength between the nozzle body 6 and the connecting pipe 5. Simultaneously, the threaded connection facilitates quick disassembly of the nozzle body 6 for easy replacement and maintenance. By embedding the sealing ring 10 into the groove 9 on the outer surface of the nozzle body 6 near the connecting pipe 5, the sealing effect between the nozzle body 6 and the connecting pipe 5 is improved, reducing lubricant leakage. Subsequently, through the sliding connection between the connecting pipe 5 and the threaded sleeve 4, the connecting pipe 5 and the nozzle body 6 are inserted into the interior of the reducer gearbox 1. The cross-section of the connector 5 is shaped like the letter "<", which allows the nozzle body 6 to directly spray lubricating oil onto the outer surface of the worm gear body 3. Then, through the meshing connection between the worm gear body 3 and the worm body 2, the lubricating oil is evenly applied to both the worm gear body 3 and the worm body 2. By symmetrically distributing two sets of connecting pipes 5 on the outer surface of the worm gear body 3, lubricating oil can be sprayed simultaneously onto both the meshing end and the meshing end of the worm gear body 3, ensuring full-cycle lubrication in the meshing area. Finally, the threaded connection between the annular sleeve 14 and the threaded sleeve 4 facilitates the quick fixing of the connecting pipe 5 to the gearbox 1 of the reducer without the need for external tools, shortening maintenance time. When maintenance of the nozzle body 6 is required later, simply reverse the annular sleeve 14 until it separates from the threaded sleeve 4 to achieve quick disassembly of the nozzle body 6, facilitating rapid replacement.
