Technical Field

[0001] The utility model relates to the field of mechanical lubrication, in particular to an optimized oil bag for lubrication equipment. Background Art

[0002] In modern industrial lubrication systems, especially in the fields of wind power lubrication, the efficiency, reliability and convenience of grease injection equipment are crucial. Traditional grease injection methods mostly use light and small grease injection pumps in combination with bagged grease, but there are many problems. On the one hand, due to the poor fluidity of grease, cavitation is prone to occur during the grease injection process, affecting the continuity and stability of grease injection, resulting in poor lubrication effect.

[0003] On the other hand, during the compression process of the grease bag, due to the limitations of the structural design, the grease in the bag cannot be fully and effectively utilized, which easily leads to grease residue and waste. At the same time, the existing grease bag design does not adequately consider the reliability of the connection between the oil outlet and the bag body, which is prone to leakage under high pressure or frequent use, affecting the normal operation of the grease injection equipment and reducing the overall service life and reliability.

[0004] In order to overcome the above-mentioned shortcomings, the inventor invented an optimized oil bag for lubricating equipment. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an optimized oil bag for lubrication equipment, which can avoid air suction during the grease injection process, will not affect the continuity and stability of the grease injection, ensure the lubrication effect, can fully and effectively utilize the grease in the bag, will not cause grease residue and waste, will not leak under high pressure or frequent use, will not affect the normal operation of the grease injection equipment, and improve the overall service life and reliability.

[0006] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0007] The optimized oil bag for lubrication equipment comprises a grease bag body and an oil outlet, wherein the oil outlet is arranged at the top center of the grease bag body, the connection between the oil outlet and the grease bag body is rounded, an end cap is arranged at the bottom of the grease bag body, the grease bag body is made of flexible material and is a corrugated cylindrical structure, and the diameter of the uppermost corrugation is smaller than the diameters of other corrugations.

[0008] As a further implementation, the bottom edge of the lowest fold is connected to the edge of the end cover.

[0009] As a further implementation, a groove is provided on the top of the needle upward along the needle surface.

[0010] As a further implementation method, the outermost bend of each layer of folds of the grease bag body is rounded.

[0011] As a further implementation, the connection between the lowermost fold and the end cover is rounded.

[0012] As a further implementation, the cross section of the end cover is circular.

[0013] As a further implementation, the fillet radius is 0.4-0.6 mm.

[0014] As a further implementation, a thread is provided on the circumferential outer surface of the oil outlet.

[0015] As a further implementation, the thread diameter is 11-13 mm.

[0016] As a further implementation, the flexible material of the grease bag body is LDPE.

[0017] As a further implementation, the thickness of the uppermost fold is 0.09-0.11 mm smaller than the thickness of the other folds.

[0018] The beneficial effects of the utility model are as follows:

[0019] The oil bag for lubricating equipment of the utility model is arranged at the top center of the grease bag body through the oil outlet, so that the grease can be discharged more easily under the action of gravity, avoiding the occurrence of air absorption, thereby not affecting the continuity and stability of grease injection. At the same time, due to the reasonable design of the oil outlet, the grease can be discharged smoothly from the oil outlet, ensuring that the grease can be delivered to the lubrication part in a timely and uniform manner, and ensuring the lubrication effect.

[0020] The utility model adopts a corrugated cylindrical structure design for the grease bag body, which can gradually shrink during use to maintain the squeezing effect on the grease, so that the grease can be more fully utilized without causing grease residue and waste. The diameter of the uppermost corrugation of the grease bag body is smaller than the diameter of other corrugations. This design is conducive to the centralized discharge of grease, further improving the oil discharge efficiency and reducing grease residue.

[0021] The utility model reduces stress concentration and fatigue damage of materials at the oil outlet by rounding the connection between the oil outlet and the grease bag body, improves the reliability and sealing of the connection, does not leak under high pressure or frequent use, does not affect the normal operation of the grease injection equipment, and improves the overall service life and reliability. At the same time, the cross-section of the end cap is circular, which can distribute the pressure more evenly, avoid damage caused by stress concentration, and improve the bearing capacity and service life of the end cap. At the same time, the connection between the circular end cap and the bottom of the grease bag body is tighter and more stable, which helps to enhance the structural integrity of the entire grease bag body, thereby reducing the risk of leakage.

[0026] Example

[0027] This embodiment provides an optimized lubricating equipment oil package, such as Figure 1-Figure 2 As shown, it includes a grease bag body 1 and an oil outlet 2. The top center of the grease bag body 1 is provided with the oil outlet 2. The connection between the oil outlet 2 and the grease bag body 1 is rounded. The oil outlet 2 is located at the top center of the grease bag body 1, so that the grease can be discharged more easily under the action of gravity. The oil outlet 2 serves as a channel for grease discharge, so that the grease can flow out of the grease bag body 1 to achieve grease supply to the lubricating equipment, reduce grease residue, and improve oil discharge efficiency. At the same time, the connection between the oil outlet 2 and the grease bag body 1 is rounded, which can reduce stress concentration, reduce fatigue damage of the material at the oil outlet 2, improve the reliability and sealing of the connection, and reduce the risk of leakage.

[0028] An end cap 3 is provided at the bottom of the grease bag body 1. The grease bag body 1 is made of a flexible material and is a corrugated cylindrical structure, and the diameter of the uppermost corrugation is smaller than the diameters of the other corrugations.

[0029] The grease bag body 1 is the main part for containing grease. The grease bag body 1 is made of flexible material, so that it can be deformed when squeezed by external force or internal pressure, so as to ensure the smooth flow of oil passage, thereby promoting the discharge of grease from the oil outlet 2; the grease bag body 1 adopts a pleated cylindrical structure design, which can not only be conveniently folded and stored when not in use to reduce the occupied space, but also during use, as the grease is discharged, the grease bag body 1 can gradually shrink to maintain the squeezing effect on the grease and ensure the continuous and stable supply of grease. The diameter of the top pleat is smaller than the diameter of other pleats, and the thickness of the top pleat is 0.09~0.11mm smaller than the thickness of other pleats. This design may be more conducive to the concentrated discharge of grease, further improve the oil discharge efficiency, and reduce the residual grease in the bag body.

[0030] The end cap 3 is installed at the bottom of the grease bag body 1 to close the bottom opening, support and protect the grease bag body 1. The cross section of the end cap 3 is circular, which enables the end cap 3 to distribute pressure more evenly when subjected to stress, avoids damage caused by stress concentration, and improves the bearing capacity and service life of the end cap 3. At the same time, the connection between the circular end cap 3 and the bottom of the grease bag body 1 is tighter and more stable, which helps to enhance the structural integrity of the entire grease bag body 1.

[0031] The bottom edge of the fold at the bottom of the grease bag body 1 is connected to the edge of the end cap 3 to achieve a firm fixation between the grease bag body 1 and the end cap 3. This design of connection can ensure that when the grease bag body 1 is squeezed or stretched, the grease bag body 1 and the end cap 3 will not be separated or loosened, and the structural stability and reliability of the entire grease bag body 1 are maintained. At the same time, the connection between the fold at the bottom of the grease bag body 1 and the end cap 3 is rounded, which can further reduce stress concentration, improve the durability of the connection part, and ensure that the grease at the connection between the fold at the bottom of the grease bag body 1 and the end cap 3 is squeezed cleanly during the grease extrusion process.

[0032] The outermost bend of each layer of wrinkles of the grease bag body 1 is rounded with a radius of 0.4-0.6 mm. This design improves the stress distribution at this part and avoids the residue of lubricating grease at this part.

[0033] The outer circumferential surface of the oil outlet 2 is provided with a thread, and the thread diameter is 11-13 mm. This is to ensure that the grease bag body 1 is stably connected to the grease gun or other grease injection equipment when the grease is injected.

[0034] The flexible material of the grease bag body 1 is LDPE. LDPE (low-density polyethylene) is a common plastic material with good processing performance and mechanical properties. LDPE has certain grease resistance, which makes it a suitable choice for grease packaging.

[0035] The use process of the optimized oil bag for lubricating equipment of the utility model is as follows:

[0036] (I) Installation preparation: Manually install the grease bag body 1 to the corresponding position of the lubrication equipment, ensure that the oil outlet 2 is correctly connected to the oil delivery channel of the equipment, and the end cover 3 is tightly fixed to the installation position of the equipment.

[0037] (ii) Grease injection: Grease is manually injected into the grease bag body 1 through a dedicated filling port or a grease gun or other tool. Pay attention to controlling the filling amount and filling speed to avoid grease overflow or insufficient filling.

[0038] (III) Sealing inspection: After the filling is completed, manually check the sealing of the grease bag body 1 to ensure that there is no grease leakage at the connection between the oil outlet 2 and the end cover 3. At the same time, check whether the grease bag body 1 is damaged or deformed.

[0039] (IV) Equipment startup and monitoring: Manually start the lubrication equipment so that the grease is discharged from the oil outlet 2 under the action of gravity during the operation of the equipment. At the same time, monitor the discharge of the grease to ensure that the grease can flow smoothly into the oil delivery channel and effectively lubricate the lubrication parts.

[0040] (V) External auxiliary operation: In some special cases, it may be necessary to manually apply a certain external force to the grease bag body 1, such as gently squeezing or tapping, to promote the discharge of grease, especially when the grease has poor fluidity or the equipment has high requirements for grease supply.

[0041] (vi) Replacement and cleaning: When the grease in the grease bag body 1 is about to be exhausted or needs to be replaced, the equipment is manually stopped, the grease bag body 1 is disassembled and replaced with a new one, and the oil delivery channel and lubrication parts of the equipment are cleaned and maintained to prepare for the next grease filling and extrusion.

[0042] The length, curvature and number of the lines of the grease bag body 1, the oil outlet 2 and the end cap 3 in the accompanying drawings are for illustration only, and those skilled in the art can make adaptive adjustments according to actual usage.
