Description

Technical Field

[0001] The invention relates to a passive waste grease collecting device and a bearing system. Background Art

[0002] For large bearings, in order to ensure good lubrication, it is necessary to discharge the waste grease in time and inject new grease. Taking the variable pitch bearing as an example, the existing technology mainly includes two categories: active and passive. The active type requires additional power, complex system structure and high cost; the passive type includes oil collection bottles, oil collection bags, oil collection pipes and other methods of collection. The oil collection bottles and oil collection bags are directly installed at the grease discharge port of the bearing through a joint. Many bottles or belts are required, which are cumbersome and troublesome to replace and handle. In order to ensure the convenience of replacement, the oil collection bottles and oil collection bags are easy to fall under the centrifugal force of the bearing rotation, polluting the surrounding environment and easily causing bumps and damage to other components installed in the surrounding environment. The oil collection pipe method has the problems of inconvenient disassembly and assembly, difficulty in grease removal, and the inability to collect full waste grease in the pipe, resulting in a low storage rate. The oil collection pipe needs to be replaced frequently. If an exhaust hole is set to exhaust the air in the pipe, the exhaust hole is easy to throw out the base oil or a small amount of waste grease. It can be seen that there is no technical solution in the existing technology that can perfectly solve the problem of waste grease collection of rotating bearings. Summary of the invention

[0003] Based on the above problems of the prior art, the present invention provides a passive waste grease collection device with low cost, easy disassembly and replacement, easy waste grease treatment, not easy to fall off and pollute the environment, and large grease storage capacity; the present invention also provides a bearing system using the above waste grease collection device.

[0004] The technical scheme of the passive waste fat collection device of the present invention is as follows: The passive waste fat collection device comprises: Vacuum tube bags are used to store waste grease. They are made of flexible materials and are in a vacuum state. The waste grease collection joint is a joint with at least three channels, and the external interfaces of each channel face different directions respectively, one of the external interfaces is used to connect with the grease discharge port of the bearing, and the other two external interfaces are detachably connected with two adjacent vacuum tube bags respectively; A retainer is sleeved outside the vacuum tube bag to limit the vacuum tube bag, and is detachably fixedly connected to an adjacent waste grease collection joint or is used to be detachably fixedly connected to a bearing; The vacuum tube bags and the waste fat collecting joints are arranged alternately in sequence to form an arc or circular structure, and there are multiple vacuum tube bags and retaining frames in one-to-one correspondence; The waste grease flows out from the bearing grease discharge port and flows into two adjacent vacuum tube bags through the waste grease collection joints. The vacuum tube bags are gradually expanded by the waste grease filled in. When the vacuum tube bags are full, new vacuum tube bags can be replaced.

[0005] The beneficial effects of the present solution are as follows: when the present application is in use, the waste grease collection joint is installed at the grease discharge port of the bearing, and after the vacuum tube bag is connected, as new grease is injected into the bearing, when the amount of grease in the bearing is too high, the excess grease will be discharged from the grease discharge port under the dual effects of the crushing of the steel ball and the centrifugal force exerted on the grease, and then enter the two adjacent vacuum tube bags through the waste grease collection joint. Since the vacuum tube bag is in a vacuum state and there is almost no air in the tube, there will be no situation in which the internally stored air hinders the entry of waste grease, that is, more storage capacity can be achieved, thereby reducing the maintenance frequency of replacing the vacuum tube bag and reducing the maintenance cost; secondly, since there is no exhaust hole structure in the vacuum tube bag, the waste grease is avoided. The problem of being thrown out from the exhaust hole and polluting the environment is solved; furthermore, the setting of the retaining frame can limit and support the vacuum tube bag, so that even if a lot of waste fat is collected in the vacuum tube bag, the vacuum tube bag will not fall off or break due to the large centrifugal force, ensuring that the surrounding environment will not be polluted by the waste fat in the vacuum tube bag that falls off, and will not cause bumps and damage to other parts; finally, since the vacuum tube bag is a disposable consumable, it is low in cost, easy to replace and disassemble, and easy to carry, which further reduces material costs and transportation costs. Moreover, since the vacuum tube bag is made of flexible material, it is easy to squeeze out or crush the tube bag and then squeeze out the waste fat inside, which greatly facilitates the subsequent treatment of the waste fat and further reduces costs.

[0006] Furthermore, the retaining frame is tubular, and both ends are detachably connected to adjacent waste fat collecting joints, and the interior of the retaining frame is connected to the atmosphere.

[0007] The beneficial effects of this solution are as follows: the retaining frame is connected and fixed to the adjacent waste fat collection joints at both ends. Compared with the solution of fixing the retaining frame on the bearing, this solution is easier to implement, because drilling or welding on the bearing is inconvenient. For example, the retaining frame can be directly fixed to the adjacent waste fat collection joint by a clamp, which is convenient and quick. However, since this solution may cause the interior of the retaining frame to be sealed, which is not conducive to the expansion of the vacuum tube bag, this problem can be avoided by providing a structure that is connected to the atmosphere.

[0008] Furthermore, a plurality of vent holes are provided on the retaining frame to enable the interior to communicate with the atmosphere.

[0009] Beneficial effects of this solution: The retaining frame of this solution has good integrity, can withstand the greatest force, has the strongest bearing capacity, and has the longest service life.

[0010] Furthermore, the retaining frame is a spiral strip structure composed of spiral strips.

[0011] The beneficial effects of this solution: the structure of the retainer of this solution is the simplest, easy to obtain, and low in cost. For example, directly purchasing a spiral spring can meet the demand.

[0015] Furthermore, the middle part of the retaining frame is used to connect to the bearing through a clamp, and the retaining frame is located between two adjacent waste fat collection joints. There is a certain distance between the two ends of the retaining frame and the corresponding adjacent waste fat collection joints. After the vacuum tube bag is inserted into the retaining frame, its two ends extend from the two ends of the retaining frame and are detachably connected to the corresponding waste fat collection joints.

[0016] Furthermore, the retaining frame is composed of a plurality of circular rings arranged at intervals and a plurality of connecting strips serially connected to the circular rings in sequence.

[0017] Furthermore, the retaining frame is a mesh tube having a plurality of mesh holes.

[0018] The technical scheme of the bearing system of the present invention is as follows: the bearing system includes a bearing, a plurality of grease discharge ports are provided on the bearing, and a passive waste grease collection device is also installed on the bearing, and the passive waste grease collection device includes: Vacuum tube bags are used to store waste grease. They are made of flexible materials and are in a vacuum state.

[0036] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0037] An embodiment of the passive waste grease collection device of the present invention: 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 fat collection device mainly includes a waste fat collection connector 4, a vacuum tube bag 2 and a retaining frame 3.

[0038] like Figure 1 , 2 As shown, the vacuum tube bag 2 is used to store waste grease and is made of a flexible material. The vacuum tube bag 2 is in a vacuum state. Figure 5 As shown, the vacuum tube bag 2 is a vacuum bag made of plastic, which is rolled into a roll. There is a cut-off line between two adjacent vacuum tube bags 2, similar to the rolling method of garbage bags. When using, pull one by one for use. Both ends of the vacuum tube bag 2 are open, and after unfolding, it is similar to a slender tubular structure. In other embodiments, other materials may also be used, such as rubber, silicone, waterproof cloth, etc.

[0039] like Figure 1-2 As shown, the waste grease collection joint 4 is at least a three-way joint, and this embodiment is a three-way joint, and the external interfaces of each channel are respectively oriented in different directions, and are roughly T-shaped. One of the external interfaces is used to dock with the grease discharge port 11 of the bearing, and the other two external interfaces are respectively detachably connected to two adjacent vacuum tube bags 2. The waste grease collection joint 4 can be made of metal or plastic material. Since it needs to be reused, the selected material must have the characteristics of wear resistance and high strength.

[0040] like Figure 1-2 As shown, the retaining frame 3 is sleeved outside the vacuum tube bag 2 to limit the vacuum tube bag 2, and is detachably fixedly connected to the adjacent waste fat collection connector 4 or used for detachably fixedly connected to the bearing. The retaining frame 3 of this embodiment is a plastic hose or an arc-shaped hard tube with exhaust holes on it.

[0041] The vacuum tube bag 2 and the waste grease collecting joint 4 are arranged alternately in sequence to form an arc or circular structure. There are multiple vacuum tube bags 2 and retaining frames 3 and they correspond one to one. After the waste grease flows out from the bearing grease discharge port 11, it flows into two adjacent vacuum tube bags 2 through the waste grease collecting joint 4. The vacuum tube bag 2 is gradually expanded by the filled waste grease. After the vacuum tube bag 2 is full, a new vacuum tube bag 2 can be replaced.

[0042] When using, Figure 1 As shown, the waste grease collection joint 4 is installed at the grease discharge port 11 of the bearing. After the vacuum tube bag 2 is connected, as the new grease in the bearing is injected, when the amount of grease in the bearing is too high, the excess grease will be discharged from the grease discharge port 11 under the dual effects of the rolling of the steel ball and the centrifugal force exerted on the grease, and then enter the two adjacent vacuum tube bags 2 through the waste grease collection joint 4. As more and more waste grease enters, as shown in FIG. Figure 2 As shown, the waste grease fills the vacuum tube bag 2, causing the vacuum tube bag 2 to be inflated and restrained by the retaining frame 3. Since the vacuum tube bag 2 is in a vacuum state and there is almost no air in the tube, there will be no situation where the internal stored air hinders the entry of waste grease, that is, more storage capacity can be achieved, thereby reducing the maintenance frequency of replacing the vacuum tube bag 2 and reducing the maintenance cost; secondly, since there is no exhaust hole structure in the vacuum tube bag 2, the problem of waste grease being thrown out from the exhaust hole and polluting the environment is avoided; furthermore, since the setting of the retaining frame 3 can limit and support the vacuum tube bag 2, even if a lot of waste grease is collected in the vacuum tube bag 2, the vacuum tube bag 2 will not fall off or break due to the large centrifugal force, ensuring that the surrounding environment will not be polluted by the waste grease in the vacuum tube bag 2 that falls off, and will not cause bumps and damage to other parts; finally, since the vacuum tube bag 2 is a disposable consumable, it is low in cost, easy to replace and disassemble, and easy to carry, further reducing material costs and transportation costs, and since the vacuum tube bag 2 is made of flexible material, it is easy to squeeze out or crush the tube bag and then squeeze out the waste grease inside, which greatly facilitates the subsequent treatment of the waste grease and further reduces costs.

[0043] In this embodiment, the retainer 3 is tubular, and its two ends are detachably connected to the adjacent waste fat collection joints 4, and the interior of the retainer 3 is connected to the atmosphere. The retainer 3 is connected and fixed to the adjacent waste fat collection joints 4 at both ends. Compared with the solution of fixing the retainer 3 on 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 fat collection joint 4 through the clamp 5, which is convenient and quick. However, since this solution may cause the interior of the retainer 3 to be sealed, which is not conducive to the expansion of the vacuum tube bag 2, this problem can be avoided by setting a structure that is connected to the atmosphere.

[0044] Specifically, a plurality of vent holes 31 are provided on the retainer 3 to enable the interior to communicate with the atmosphere. The retainer 3 of this solution has good integrity, can withstand the greatest force, has the strongest bearing capacity, and has the longest service life.

[0045] like Figure 3 As shown, the retainer 3 may also be a spiral strip structure 35 composed of spiral strips. In this solution, the retainer 3 has the simplest structure, is easy to obtain, and has low cost. For example, directly purchasing a spiral spring can meet the demand.

[0046] like Figure 4 As shown, the retaining frame 3 may also be composed of a plurality of circular rings 32 arranged at intervals and a plurality of connecting strips 33 serially connected to the circular rings 32 in sequence.

[0047] In other embodiments, the retaining frame 3 may also be a tubular structure with a certain strength and multiple mesh holes, such as a mesh tube or a permeable tube with multiple mesh holes. The retaining frame 3 is not limited to a round tube, but may also be a square tube or other shaped tubular structures and 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 fat therein.

[0048] In this embodiment, the vacuum tube bag 2 is detachably connected to the adjacent waste fat collection joint 4 by means of a clamp 5. Both ends of the retaining frame 3 are detachably connected to the adjacent waste fat collection joint 4 by means of a clamp 5. The vacuum tube bag 2 and the retaining frame 3 share a set of clamps 5, and the retaining frame 3 and the vacuum tube bag 2, which are mutually sleeved, are clamped at the same time.

[0049] In other embodiments, the middle part of the retaining frame 3 is used to connect to the bearing through the clamp 5, the retaining frame 3 is located between two adjacent waste fat collection joints 4, and the two ends of the retaining frame 3 are respectively spaced apart from the corresponding adjacent waste fat collection joints 4. After the vacuum tube bag 2 is inserted into the retaining frame 3, its two ends extend out from the two ends of the retaining frame 3 and are respectively detachably connected to the corresponding waste fat collection joints 4.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the contents of the description and drawings of the present invention should also be included in the protection scope of the present invention.
