Description

Technical Field

[0001] This utility model relates to a passive waste grease collection device and a bearing system. Background Technology

[0002] For large bearings, to ensure proper lubrication, it is necessary to promptly drain old grease and inject new grease. Taking pitch bearings as an example, existing technologies mainly fall into two categories: active and passive. Active methods require additional power, have complex system structures, and are costly. Passive methods include collecting grease using oil collection bottles, bags, or pipes. Oil collection bottles and bags are directly and independently installed at the bearing's grease drain port via connectors, requiring many bottles or bags, making replacement cumbersome, time-consuming, and troublesome. Furthermore, to ensure ease of replacement, oil collection bottles and bags are prone to falling off under the centrifugal force of bearing rotation, polluting the surrounding environment and easily causing collisions and damage to other components installed nearby. The pipe method suffers from inconvenient disassembly and assembly, difficulty in grease removal, and low storage rates due to the inability to collect all the waste grease in the pipe, requiring frequent pipe replacement. If an vent is installed to remove air from the pipe, base oil or a small amount of waste grease may be ejected from the vent. Therefore, existing technologies do not offer a perfect solution for collecting waste grease from rotating bearings. Utility Model Content

[0003] Based on the above-mentioned problems of the prior art, this utility model provides a passive waste grease collection device that is low in cost, easy to replace, convenient to dispose of waste grease, not easy to fall off and pollute the environment, and has a large grease storage capacity; this utility model also provides a bearing system using the above-mentioned waste grease collection device.

[0004] The technical solution of this utility model's passive waste grease collection device is as follows: The passive waste grease collection device includes:

[0005] Vacuum tube bags are used to store waste grease. They are made of flexible material and are kept in a vacuum state.

[0006] The waste grease collection connector is a three-way connector, with the external interface of each channel facing different directions. One external interface is used to connect with the grease discharge port of the bearing, and the other two external interfaces are detachably connected to two adjacent vacuum tube bags.

[0007] A retainer, fitted over the vacuum tube bag to limit its position, is detachably and securely connected to the adjacent waste grease collection connector or is detachably and securely connected to the bearing.

[0008] Vacuum tubes and waste grease collection connectors are arranged alternately to form an arc or circular structure, and there are multiple vacuum tubes and holders that correspond one-to-one;

[0009] After the waste grease flows out of the bearing grease outlet, it flows through the waste grease collection connector to two adjacent vacuum tubes. The vacuum tubes are gradually expanded by the waste grease. Once the vacuum tubes are full, they can be replaced with new ones.

[0010] The beneficial effects of this solution are as follows: In use, the waste grease collection connector is installed at the grease outlet of the bearing. After the vacuum tubes are connected, as new grease is injected into the bearing, if the amount of grease in the bearing is too high, the excess grease will be discharged from the outlet under the combined action of the steel ball's crushing force and the centrifugal force. It then enters two adjacent vacuum tubes through the waste grease collection connector. Because the vacuum tubes are in a vacuum state, there is almost no air inside, so there is no situation where internal air hinders the entry of waste grease. This allows for greater storage capacity, thereby reducing the frequency of vacuum tube replacement and lowering maintenance costs. Secondly, since there is no venting structure inside the vacuum tubes, waste grease is prevented from being discharged. The vacuum tube bag is designed to prevent environmental pollution from being ejected through the vent. Furthermore, the retainer provides support and restraint, preventing the bag from detaching or breaking due to centrifugal force even when a large amount of waste grease is collected. This ensures the surrounding environment is not contaminated by the grease and avoids damage to other components. Finally, the vacuum tube bag is a disposable item, making it inexpensive, easy to replace and disassemble, and convenient to carry, further reducing material and transportation costs. Moreover, its flexible material allows for easy extrusion or breaking of the bag to remove the waste grease, greatly simplifying subsequent waste grease treatment and further reducing costs.

[0011] Furthermore, the retainer is tubular, with both ends detachably connected to adjacent waste grease collection joints, and the interior of the retainer is open to the atmosphere.

[0012] The beneficial effects of this solution are as follows: The retainer is fixed by connecting both ends to the adjacent waste grease collection connector. Compared with the solution of fixing the retainer to the bearing, this solution is easier to implement because drilling or welding on the bearing is inconvenient. For example, the retainer can be directly fixed to the adjacent waste grease collection connector by clamps, which is convenient and quick. However, since this solution may cause the inside of the retainer to be sealed, which is not conducive to the expansion of the vacuum tube bag, this problem can be avoided by setting a structure that is open to the atmosphere.

[0013] Furthermore, the cage is equipped with multiple ventilation holes to allow the interior to communicate with the atmosphere.

[0014] The beneficial effects of this solution are: due to its good overall integrity, the cage of this solution can withstand the greatest force, has the strongest load-bearing capacity, and the longest service life.

[0015] Furthermore, the cage is a spiral structure composed of spiral strips.

[0016] The advantages of this solution are: the cage structure is the simplest and easiest to obtain, and the cost is low; for example, simply purchasing a coil spring can meet the requirements.

[0017] Furthermore, the vacuum tube bag is made of plastic.

[0018] Furthermore, the vacuum tube bag and the adjacent waste grease collection joint are detachably connected by a clamp.

[0019] Furthermore, the two ends of the retainer are detachably connected to the adjacent waste grease collection joints using clamps.

[0020] Furthermore, the middle part of the retainer is used to connect to the bearing via a clamp. The retainer is located between two adjacent waste grease collection joints. The two ends of the retainer are respectively spaced from the corresponding adjacent waste grease collection joints. After the vacuum tube bag is inserted into the retainer, its two ends extend from the two ends of the retainer and are detachably connected to the corresponding waste grease collection joints.

[0021] Furthermore, the cage consists of multiple spaced-apart rings and multiple connecting strips connected in series on each ring.

[0022] Furthermore, the cage is a perforated tube with multiple mesh openings.

[0023] The technical solution of the bearing system of this utility model is as follows: The bearing system includes a bearing, which is provided with multiple grease discharge ports. A passive waste grease collection device is also installed on the bearing. The passive waste grease collection device includes:

[0024] Vacuum tube bags are used to store waste grease. They are made of flexible material and are kept in a vacuum state.

[0048] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0049] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0050] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0051] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0052] One embodiment of the passive waste grease collection device of this utility model: This embodiment is an example of waste grease collection applied to a pitch bearing 1, such as... Figure 1-2 As shown, the passive waste grease collection device mainly includes a waste grease collection connector 4, a vacuum tube bag 2, and a retainer 3.

[0053] like Figure 1 , 2 As shown, the vacuum tube bag 2 is used to store waste lubricating grease and is made of flexible material. The inside of the vacuum tube bag 2 is in a vacuum state, as shown. Figure 5As shown, the vacuum tube bag 2 is a vacuum bag made of plastic, rolled into a roll. There is a cut line between two adjacent vacuum tube bags 2, similar to the rolling method of garbage bags. When using, one is pulled out one at a time. Both ends of the vacuum tube bag 2 are open, and when unfolded, it resembles a long and thin tubular structure. In other embodiments, other materials can also be used, such as rubber, silicone, waterproof cloth, etc.

[0054] like Figure 1-2 As shown, the waste grease collection connector 4 is a connector with at least three tees. In this embodiment, it is a three-way connector, with the external interfaces of each channel facing different directions, roughly in a T-shape. One external interface is used to connect with the grease discharge port 11 of the bearing, and the other two external interfaces are detachably connected to two adjacent vacuum tubes 2. The waste grease collection connector 4 can be made of metal or plastic. Since it needs to be reused, the selected material must have the characteristics of wear resistance and high strength.

[0055] like Figure 1-2 As shown, the retainer 3 is fitted over the vacuum tube bag 2 to limit the vacuum tube bag 2, and can be detachably fixedly connected to the adjacent waste grease collection connector 4 or used for detachably fixedly connected to the bearing. In this embodiment, the retainer 3 is a plastic hose or an arc-shaped rigid tube with an exhaust hole.

[0056] Vacuum tube bags 2 and waste grease collection connectors 4 are arranged alternately to form an arc or circular structure. There are multiple vacuum tube bags 2 and cages 3, and they correspond one to one. After the waste grease flows out of the bearing grease outlet 11, it flows through the waste grease collection connectors 4 to two adjacent vacuum tube bags 2. The vacuum tube bags 2 are gradually expanded by the waste grease. After the vacuum tube bags 2 are full, they can be replaced with new vacuum tube bags 2.

[0057] When using, such as Figure 1 As shown, the waste grease collection connector 4 is installed at the grease outlet 11 of the bearing. After the vacuum tube bag 2 is connected, as new grease is injected into the bearing, if the amount of grease in the bearing is too high, the excess grease will be discharged from the grease outlet 11 under the combined action of the steel ball's crushing force and the centrifugal force on the grease. It then enters the two adjacent vacuum tube bags 2 through the waste grease collection connector 4. As more and more waste grease enters, such as... Figure 2As shown, waste grease fills the vacuum tube bag 2, causing the vacuum tube bag 2 to expand and be restrained by the retainer 3. Because the vacuum tube bag 2 is in a vacuum state with almost no air inside, there is no risk of internal air obstructing the entry of waste grease. This allows for greater storage capacity, reducing the frequency of maintenance and maintenance costs. Secondly, since there is no venting structure inside the vacuum tube bag 2, the problem of waste grease being thrown out and polluting the environment is avoided. Furthermore, the retainer 3 provides restraint and support for the vacuum tube bag 2, preventing it from falling off or breaking due to centrifugal force even when a large amount of waste grease is collected. This ensures that the surrounding environment is not contaminated by the waste grease from the detached vacuum tube bag 2, and that it does not cause damage to other components. Finally, as the vacuum tube bag 2 is a disposable item, it is inexpensive, easy to replace and disassemble, and convenient to carry, further reducing material and transportation costs. Moreover, because the vacuum tube bag 2 is made of flexible material, it is easy to squeeze out or break the tube bag to expel the waste grease, greatly simplifying the subsequent waste grease disposal process and further reducing costs.

[0058] In this embodiment, the retainer 3 is tubular, with both ends detachably connected to adjacent waste grease collection connectors 4. The interior of the retainer 3 is open to the atmosphere. The retainer 3 is fixed by connecting both ends to adjacent waste grease collection connectors 4. Compared to fixing the retainer 3 to the bearing, this solution is easier to implement because drilling or welding on the bearing is inconvenient. For example, the retainer 3 can be directly fixed to the adjacent waste grease collection connector 4 using clamps 5, which is convenient and quick. However, this solution may result in the retainer 3 being sealed inside, which is not conducive to the expansion of the vacuum tube bag 2. Therefore, by providing a structure open to the atmosphere, this problem can be avoided.

[0059] Specifically, the cage 3 is provided with multiple vents 31 to allow the interior to communicate with the atmosphere. Due to its good overall integrity, this design of the cage 3 can withstand the greatest force, has the strongest load-bearing capacity, and the longest service life.

[0060] like Figure 3 As shown, the cage 3 can also be a spiral bar structure 35 composed of spiral strips. This type of cage 3 has the simplest and most readily available structure, and is low in cost; for example, a helical spring can be purchased directly to meet the requirements.

[0061] like Figure 4 As shown, the retainer 3 can also be composed of multiple spaced-apart rings 32 and multiple connecting strips 33 connected in series on each ring 32.

[0062] In other embodiments, the retainer 3 can also be a tubular structure with a certain strength and multiple meshes, such as a mesh tube or a permeable tube. The retainer 3 is not limited to a round tube, but can also be a square tube or other tubular or non-tubular structures, as long as it can limit the vacuum tube bag 2 and bear the gravity and centrifugal force generated by the vacuum tube bag 2 and the waste grease inside.

[0063] In this embodiment, the vacuum tube bag 2 is detachably connected to the adjacent waste grease collection connector 4 using a clamp 5. Both ends of the retainer 3 are detachably connected to the adjacent waste grease collection connector 4 using clamps 5. Furthermore, the vacuum tube bag 2 and the retainer 3 share a single set of clamps 5, which simultaneously tighten the interlocking retainer 3 and vacuum tube bag 2.

[0064] In other embodiments, the middle part of the retainer 3 is used to connect to the bearing via the clamp 5. The retainer 3 is located between two adjacent waste grease collection joints 4. The two ends of the retainer 3 are respectively spaced apart from the corresponding adjacent waste grease collection joints 4. After the vacuum tube bag 2 is inserted into the retainer 3, its two ends extend out from the two ends of the retainer 3 and are respectively detachably connected to the corresponding waste grease collection joints 4.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
