Description

Technical Field

[0001] This utility model belongs to the technical field of gearboxes, specifically relating to a high-strength gearbox with built-in reinforcing ribs. Background Art

[0002] In the field of industrial transmission, gearboxes, as key components, must withstand enormous loads and impacts. Traditional gearboxes have limited strength and are prone to deformation, wear, and even damage under high loads and long-term operation, affecting the normal operation and service life of equipment. To improve gearbox performance and meet the growing industrial demands, a high-strength gearbox with built-in reinforcing ribs has emerged. Through optimized structural design, it significantly enhances the strength and stability of the gearbox, effectively solving the pain points of traditional products.

[0003] Existing technologies lack effective means to precisely control oil flow and injection volume, making it difficult to ensure that oil accurately reaches key parts inside the gearbox. This results in inaccurate oil injection control. A structure is needed that can propel oil within the gearbox body, allowing the internal oil to fully penetrate between the screw and screw connection, thereby increasing the service life of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a high-strength gearbox with built-in reinforcing ribs to solve the problem that the prior art lacks an effective means to precisely control the flow and injection volume of oil, making it difficult to ensure that the oil accurately reaches the key parts inside the gearbox and resulting in inaccurate oil injection control.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-strength gearbox with built-in reinforcing ribs, comprising a gearbox body and an upper cover plate disposed on the upper side of the gearbox body;

[0006] A screw drive port is provided at the upper right end of the gearbox body, and a second drive port is provided at the lower side of the screw drive port.

[0007] The gearbox body has internal reinforcing ribs at the upper and lower ends of its inner side.

[0008] A sealing cylinder is provided on the upper left side of the upper cover plate, a sealing valve is provided in the middle of the sealing cylinder, a pressing rod is provided in the middle of the upper side of the sealing valve, and an oil inlet pipe is provided on the lower left side of the sealing cylinder.

[0009] An oil drain pipe is provided on the right side of the sealing cylinder, and a sealing sleeve is provided on the upper side of the oil drain pipe.

[0010] Preferably, the upper cover plate is connected to the gearbox body by bolts, and a sealing ring is provided at the connection position between the lower side of the upper cover plate and the gearbox body for sealing.

[0011] Preferably, the sealing cylinder is connected to the upper cover plate by welding, and a through hole is provided at the connection between the sealing cylinder and the upper cover plate.

[0012] Preferably, the oil inlet pipe is connected to an external oil supply device, and the sealing valve is in close contact with the inner wall of the sealing cylinder.

[0013] Preferably, a sealing ring is provided at the connection between the pressing rod and the sealing cylinder for sealing treatment, and the pressing rod can move up and down inside the sealing cylinder.

[0014] Preferably, a through hole is provided at the middle connection position between the oil drain pipe and the upper cover plate, the sealing sleeve is connected to the oil drain pipe by a threaded connection, and a sealing ring is provided at the connection position between the sealing sleeve and the oil drain pipe for sealing treatment.

[0015] Preferably, a plurality of bases are provided on the lower side of the gearbox body, and threaded holes for connecting external bolts are respectively provided at the middle positions of the front and rear ends of the bases, and a control box is provided on the outer left front side of the gearbox body.

[0016] Compared with the prior art, this utility model provides a high-strength gearbox with built-in reinforcing ribs, which has the following beneficial effects:

[0017] The sealing valve, working in conjunction with the push rod within the sealing cylinder, plays a crucial role. The push rod allows operators to easily and precisely control the valve's position within the cylinder. Pushing the push rod upwards opens the valve, unblocking the passage between the oil inlet pipe and the gearbox body, allowing oil to flow smoothly. Pressing it downwards closes the passage and forces the oil within the sealing cylinder to critical areas inside the gearbox, such as the screw and the gaps between the screw connections. This precise control over oil flow and injection ensures effective lubrication of critical components. Simultaneously, the valve's tight contact with the inner wall of the sealing cylinder enhances the overall sealing of the lubrication system when closed.

[0018] The sealing sleeve is connected to the drain pipe via threads, enabling flexible control of the drain channel. If there is too much oil during the oil filling process, unscrewing the sealing sleeve allows the excess oil to be discharged through the drain pipe, preventing excessive internal pressure, ensuring safe operation of the equipment, and maintaining system pressure balance. When oil filling is complete or draining is not required, tightening the sealing sleeve further enhances the sealing performance at the connection point with the drain pipe, preventing oil leakage.

[0019] The drain pipe provides a channel for excess oil to be discharged, playing an important role in maintaining the internal pressure balance and stable oil volume of the oil injection system, ensuring a smooth oil injection process and normal operation of the equipment under different working conditions.

[0020] In summary, these structures work together to not only achieve precise control and efficient execution of the gearbox lubrication process, ensuring adequate lubrication of key parts of the gearbox, but also improve the safety and stability of equipment operation through excellent sealing performance and pressure control, reduce malfunctions that may be caused by oil problems, and extend the service life of the equipment.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] This utility model provides, for example Figure 1-6The high-strength gearbox with built-in reinforcing ribs shown includes a gearbox body 1 and an upper cover plate 2 disposed on the upper side of the gearbox body 1.

[0030] A screw drive port 3 is provided at the upper right end of the gearbox body 1, and a second drive port 4 is provided at the lower side of the screw drive port 3.

[0031] Inner reinforcing ribs 13 are provided at the upper and lower ends of the inner side of the gearbox body 1;

[0032] A sealing cylinder 7 is provided on the upper left side of the upper cover plate 2. A sealing valve 12 is provided in the middle of the sealing cylinder 7. A pressing rod 9 is provided in the middle of the upper side of the sealing valve 12. An oil inlet pipe 10 is provided on the lower left side of the sealing cylinder 7.

[0033] An oil drain pipe 11 is provided on the right side of the sealing cylinder 7, and a sealing sleeve 8 is provided on the upper side of the oil drain pipe 11.

[0034] Multiple bases 5 are provided on the lower side of the gearbox body 1, and threaded holes for connecting external bolts are provided at the middle of the front and rear ends of the bases 5. A control box 6 is provided on the outer left front side of the gearbox body 1.

[0035] In this embodiment, a plurality of bases 5 are provided on the lower side of the gearbox body 1. The gearbox is securely fixed in the required position using external bolts through the threaded holes at the middle positions of the front and rear ends of the bases 5. A control box 6 is installed on the outer left front side of the gearbox body 1. The control box 6 is used to comprehensively control and adjust the operation of the gearbox to ensure that it works according to the predetermined parameters and modes.

[0036] The upper cover plate 2 is tightly connected to the gearbox body 1 by bolts, and a sealing ring is carefully installed at the connection point. This sealing ring plays a crucial sealing role. On the one hand, it can effectively prevent the leakage of lubricating oil and other substances inside the gearbox, avoiding pollution to the surrounding environment and affecting the normal operation of the gearbox due to lack of lubricating oil. On the other hand, it can prevent external impurities from entering the gearbox, ensuring the cleanliness of the gearbox interior and a good working environment.

[0037] A screw drive port 3 is located at the upper right end of the gearbox body 1, and a second drive port 4 is located at its lower end. In actual operation, multiple screws can be installed inside the gearbox, and these screws are connected to an external drive device via the screw drive port 3. The external drive device provides power to the screws, causing them to rotate in a specific direction and speed. This screw-driven method is quite common in existing technology. The rotation of the screws drives other cooperating transmission components within the gearbox, thereby enabling various operational tasks of the gearbox, such as power transmission, speed changes, and direction adjustments. The second drive port 4 can also be connected to a corresponding power source, providing more power options and combinations for the gearbox's operation to meet different operational needs.

[0038] Inner reinforcing ribs 13 are provided at the upper and lower ends of the inner side of the gearbox body 1. These inner reinforcing ribs act like the "skeleton" of the gearbox, greatly enhancing the structural strength of the gearbox body. During gearbox operation, it will be subjected to forces and pressures from all directions. The inner reinforcing ribs can effectively disperse and bear these external forces, allowing the gearbox to maintain a stable structural shape even under large power and pressure conditions, and preventing deformation. This ensures the normal operation and long service life of the gearbox.

[0039] During prolonged operation of the gearbox, excessive lubricating oil may occur, or the lubricating oil may need to be changed. In this case, excess or replaced lubricating oil can be drained through the drain pipe 11. A through hole is provided at the midpoint between the drain pipe 11 and the upper cover plate 2 to ensure smooth passage of lubricating oil. When draining is not required, the sealing sleeve 8 is securely installed on the drain pipe 11 via a threaded connection, and a sealing ring is provided at the connection point to achieve a good seal and prevent lubricating oil leakage. When draining is necessary, the operator simply unscrews the sealing sleeve 8, and the lubricating oil can be smoothly drained from the drain pipe 11, completing the lubricating oil replacement or adjustment.

[0040] like Figure 1-6 As shown, the upper cover plate 2 is connected to the gearbox body 1 by bolts, and a sealing ring is provided at the connection position between the lower side of the upper cover plate 2 and the gearbox body 1 for sealing. The sealing cylinder 7 is connected to the upper cover plate 2 by welding, and a through hole is provided at the connection between the sealing cylinder 7 and the upper cover plate 2. The oil inlet pipe 10 is connected to the external oil supply equipment. The sealing valve 12 is in close contact with the inner wall of the sealing cylinder 7. A sealing ring is provided at the connection position between the pressing rod 9 and the sealing cylinder 7 for sealing, and the pressing rod 9 can move up and down inside the sealing cylinder 7. A through hole is provided at the connection position between the oil drain pipe 11 and the upper cover plate 2. The sealing sleeve 8 is connected to the oil drain pipe 11 by thread, and a sealing ring is provided at the connection position between the sealing sleeve 8 and the oil drain pipe 11 for sealing.

[0041] Preferably, the operator first connects the external oil supply equipment to the oil inlet pipe 10 to ensure that the connection is secure and well-sealed, in preparation for the subsequent oil injection operation.

[0042] Before starting to fill oil into the gearbox body 1, the operator unscrews the sealing sleeve 8 by thread, exposing the drain pipe 11. This step is to ensure that any excess oil has a drainage channel during the filling process, preventing excessive pressure or other problems caused by too much oil.

[0043] The sealing valve 12 is moved upwards within the sealing cylinder 7 by the pressing rod 9 until it reaches the top and stops. At this point, the sealing valve 12 no longer obstructs the passage between the oil inlet pipe 10 and the gearbox body 1, creating conditions for the oil to smoothly enter the gearbox body 1.

[0044] Oil is introduced into the gearbox body 1 using an external oil supply device. The oil flows into the sealing cylinder 7 along the oil inlet pipe 10, and then enters the gearbox body 1 through the open channel. As the oil is continuously introduced, the oil level gradually rises.

[0045] Once the oil volume reaches the upper level of the oil inlet pipe 10 inside the sealing cylinder 7, the operator connects the sealing sleeve 8 to the drain pipe 11 via threads for sealing. This step ensures the entire oil injection system is sealed again, preventing oil leakage.

[0046] After sealing is completed, the operator presses the sealing valve 12 downward inside the sealing cylinder 7. As the sealing valve 12 is pressed down, the oil inside the sealing cylinder 7 is pressured and forced into the gearbox body 1, especially fully immersing itself in the gaps between the screw and the screw connection inside the gearbox body 1, ensuring that these critical parts are adequately lubricated.

[0047] To ensure sufficient lubrication for all components inside the gearbox body 1, the operator can repeat the above steps multiple times. Each time, the operation should be performed in the following sequence: unscrew the sealing sleeve, open the sealing valve, inject oil, seal, and press down the sealing valve to complete the oil introduction operation.

[0048] Throughout operation, this structure prevents oil overflow. During the oil filling process, excess oil can be drained through the initially opened drain pipe, preventing overflow. Furthermore, if insufficient lubricating oil is found in the gearbox body 1 during subsequent operation, the same procedure can be repeated to add more oil into the sealing cylinder 7, ensuring proper gearbox operation and optimal lubrication of components.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
