Description

Technical Field

[0001] This utility model belongs to the technical field of gear transmission devices, and more specifically, it relates to a welded double gear structure. Background Technology

[0002] A double gear is a mechanical device consisting of two interconnected gears. They typically have different numbers of teeth or different sizes and transmit motion and force through meshing. This structure can be used in a variety of applications, including gear reducers, transmission devices, and some complex mechanical systems.

[0003] Based on the above, the inventors have discovered the following problems: Existing welded double gears are prone to wear during use. Most gears use internal lubricating oil to reduce wear, but when the gear stops running, the lubricating oil will flow out, resulting in a large consumption of lubricating oil and waste.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a welded double gear structure in order to achieve a more practical value. Utility Model Content

[0005] The purpose and effect of this utility model's welded double gear structure are achieved through the following specific technical means: A welded double gear structure includes a first gear, a connecting shaft, and a second gear. The connecting shaft has a pair of connecting parts at both ends, which are welded to the first gear and the second gear, respectively. A lubrication assembly is provided inside the connecting shaft.

[0006] Furthermore, the lubrication assembly includes an oil reservoir inside the connecting shaft, with several oil outlets on both sides of the oil reservoir, several oil pipes installed on both sides of the connecting shaft, the oil outlets communicating with the oil pipes, several oil inlets on the inner sides of both gear one and gear two, the oil pipes being embedded and connected to the oil inlets, and an oil filling port at the top of the connecting shaft.

[0007] Furthermore, both gear one and gear two have several flow dividers inside, and the flow dividers are connected to the oil pipes.

[0008] Furthermore, one end of the diversion channel is provided with an oil outlet II, and a movable plug is slidably installed inside the oil outlet II. A sealing plug is installed at one end of the movable plug located inside the diversion channel, and a circular seat is installed at one end of the movable plug located outside the gear I.

[0009] Furthermore, a groove is provided around the second oil outlet, a slider is installed around the movable plug, a spring is installed on one side of the slider, one end of the spring is connected to the groove, and the spring is fitted around the movable plug.

[0010] Furthermore, a plurality of teeth are equidistantly mounted on the circumference of the gear.

[0011] Furthermore, a plurality of teeth are equidistantly installed on the circumference of the gear two.

[0012] Furthermore, a shaft hole is provided on one side of the connecting shaft, and a limit block is installed on the inner wall of the shaft hole.

[0013] Compared with the prior art, the present invention has the following beneficial effects: By using the oil reservoir, oil outlet 1, oil pipe, oil inlet, and distribution channel in a coordinated manner, the connecting shaft adds lubricant to the oil reservoir through the oil filling port. The lubricant enters the oil pipe from oil outlet 1, then flows through the oil pipe to the oil inlet, and finally enters the distribution channel to deliver lubricant to gear 1 and gear 2, keeping gear 1 and gear 2 in a lubricated state at all times, reducing friction, and improving the service life of gear 1 and gear 2.

[0014] Through the coordinated operation of the oil outlet, movable plug, sealing plug, circular seat, slide groove, slider, and spring, when gears one and two mesh and rotate with other gears, the teeth on the other gears press against the circular seat. The circular seat presses against the movable plug, which in turn moves the sealing plug into the distribution groove. The lubricant in the distribution groove flows into the oil outlet and from the periphery of the circular seat to the surface of the gear. When the circular seat is not pressed, the spring drives the slider to reset along the path of the slide groove. Under the elastic force of the spring, the movable plug moves outward with the slider. The sealing plug blocks the oil outlet, preventing lubricant from flowing out, avoiding waste, extending the service life of the lubricant, and improving practicality. Attached Figure Description

[0023] Example: As attached Figure 1 To be continued Figure 4 As shown: This utility model provides a welded double gear structure, including a first gear 1, a connecting shaft 2 and a second gear 3. The two ends of the connecting shaft 2 are provided with a pair of connecting parts 6, which are welded to the first gear 1 and the second gear 3 respectively. A lubrication assembly is provided inside the connecting shaft 2.

[0024] The lubrication assembly includes an oil reservoir 7 located inside the connecting shaft 2. The oil reservoir 7 has several oil outlets 8 on both sides. Several oil pipes 9 are installed on both sides of the connecting shaft 2. The oil outlets 8 are connected to the oil pipes 9. Several oil inlets 4 are located on the inner sides of the gear 1 and gear 2 3. The oil pipes 9 are embedded and connected to the oil inlets 4. An oil filling port is located at the top of the connecting shaft 2.

[0025] Both gear 1 and gear 2 are equipped with several flow channels 5 inside. The flow channels 5 are connected to the oil pipe 9. Through the cooperation of the oil storage tank 7, oil outlet 8, oil pipe 9, oil inlet 4 and flow channels 5, the connecting shaft 2 adds lubricant to the oil storage tank 7 through the oil injection port. The lubricant enters the oil pipe 9 from the oil outlet 8, then flows to the oil inlet 4 through the oil pipe 9, and finally enters the flow channels 5 to deliver lubricant to gear 1 and gear 2, so that gear 1 and gear 2 are always in a lubricated state, reducing friction and improving the service life of gear 1 and gear 2.

[0026] The flow divider 5 has an oil outlet 2 10 at one end, and a movable plug 11 is slidably installed inside the oil outlet 2 10. A sealing plug 15 is installed at one end of the movable plug 11 located inside the flow divider 5, and a circular seat 16 is installed at one end of the movable plug 11 located outside the gear 1.

[0027] The oil outlet 10 has a groove 13 on its periphery, and a slider 12 is installed on the periphery of the movable plug 11. A spring 14 is installed on one side of the slider 12, and one end of the spring 14 is connected to the groove 13. The spring 14 is fitted around the movable plug 11. Through the cooperation of the oil outlet 10, movable plug 11, sealing plug 15, circular seat 16, groove 13, slider 12, and spring 14, when gear 1 and gear 2 rotate in mesh with other gears, the teeth on the other gears engage with the circular seat 16. When the circular seat 16 is compressed, it compresses the movable plug 11. The movable plug 11 drives the sealing plug 15 to move into the diversion groove 5. The lubricant in the diversion groove 5 flows into the oil outlet and from the periphery of the circular seat 16 to the surface of the gear. When the circular seat 16 is not compressed, the spring 14 drives the slider 12 to return to its original position along the path of the slide groove 13. Under the elastic force of the spring 14, the movable plug 11 moves outward with the slider 12. The sealing plug 15 blocks the oil outlet 10 to prevent the lubricant from flowing out, avoid waste, extend the service life of the lubricant, and improve practicality.

[0028] The gear 1 has several teeth 19 evenly spaced on its circumference, and the gear 1 is connected to the transmission gear through the teeth 19.

[0029] Among them, a plurality of teeth 20 are installed at equal intervals around the circumference of the gear 2 3, and the gear 2 3 is connected to the transmission gear through the teeth 20.

[0030] The connecting shaft 2 has a shaft hole 17 on one side, and a limit block 18 is installed on the inner wall of the shaft hole 17.

[0031] The specific usage and function of this embodiment are as follows: First, check the integrity of the device. Only after confirming it is correct can it be used. During use, first add lubricant to the oil reservoir 7 through the oil inlet of the connecting shaft 2. The lubricant enters the oil pipe 9 from the oil outlet 8, then flows through the oil pipe 9 to the oil inlet 4, and finally enters the distribution groove 5, supplying lubricant to gears 1 and 3, ensuring they are always lubricated and reducing friction. When gears 1 and 3 mesh and rotate with other gears, the teeth on the other gears press against the circular seat 16, which in turn presses against the movable plug 11. The movable plug 11 drives the sealing plug 15 to move into the diversion groove 5. The lubricant in the diversion groove 5 flows into the oil outlet and from the periphery of the circular seat 16 to the surface of the gear. When the circular seat 16 is not squeezed, the spring 14 drives the slider 12 to return to its original position along the path of the slide groove 13. Under the elastic force of the spring 14, the movable plug 11 moves outward with the slider 12. The sealing plug 15 blocks the oil outlet 10 to prevent the lubricant from flowing out, avoid waste, extend the service life of the lubricant, and improve practicality. This device has a novel overall design and simple structure, so it is worth promoting and using widely.
