[0027] See attached document Figure 1 This application provides a detailed description of a bearing housing with a lubrication system according to an embodiment. Figure 1 A flowchart of a bearing housing with a lubrication system provided in this application;
[0028] In short, the basic technical solution of this utility model is briefly described as follows:
[0029] This application provides a bearing housing with a lubrication system. The bearing housing 1 includes a lubrication system comprising a cavity 11, an oil pump 12, and an oil pipe. The lower part of the bearing housing 1 has a cavity that can serve as an oil tank for storing lubricating oil. The cavity 11 and the oil pump 12 are connected by an oil pipe. The oil pump 12 provides power to the lubricating oil, and the oil pipe provides a passage for transporting the lubricating oil. The oil pump 12 and the bearing housing 1 are connected by an oil pipe, and the oil pump 12 and the oil pipe are disposed on the outer wall of the bearing housing 1.
[0030] The bearing housing with a lubrication system provided in this application has a simple structure. The cavity 11 is set in the bearing housing 1, which does not need to occupy a separate space. It has low cost, does not require an independent oil station, and reduces the number of oil pipes by about 90%, thus reducing the workload of installation and maintenance.
[0031] The following is a detailed discussion of a bearing housing with a lubrication system provided in this application.
[0032] like Figure 1 As shown, this application provides a bearing housing with a lubrication system. The bearing housing 1 has a cavity at its lower part, which serves as an oil tank. The bearing housing 1 includes the lubrication system mentioned in the above embodiments. The lubrication system includes a cavity 11, which is a device for supplying, recovering, settling, and storing lubricating oil. An oil pump 12 provides power for the flow of lubricating oil in the lubrication system, supplying lubricating oil to the bearing housing 1. A motor 13 is located outside the oil pump 12 to provide power to the oil pump 12. The shaft of the oil pump 12 and the shaft of the motor 13 are connected by a coupling. The oil pump 12 provides power to the lubricating oil, which flows from the bottom cavity 11 of the bearing housing 1 to the oil pump inlet, is pressurized by the oil pump, and is finally sent back to the bearing housing 1. It should be noted that the bearing housing 1 supports the main motor rotor shaft (the main motor rotor shaft includes the journal), and the oil pipe is the pipeline for the flow of lubricating oil, that is, the oil pipe provides a passage for transporting lubricating oil. The motor 13 is located outside the oil pump 12, providing power to the oil pump 12 while avoiding interference between the motor 13 and other hydraulic management and components. The oil pump 12, oil pipe and motor 13 are arranged on the outer walls of both sides of the bearing housing 1. In a specific embodiment, a frame is arranged on the outer walls of both sides of the bearing housing 1. The motor 13, oil pump 12, oil pipe, valve block, filter 16 and detection device can all be installed on the frame. The purpose of this design is to save space occupied by the oil station, thereby greatly reducing the length of the oil circuit (i.e. oil pipe), improving efficiency and saving costs.
[0033] In one specific embodiment, in order to save installation space, reduce the distance of oil pipes, facilitate operation and maintenance, and save costs, a frame is provided on one side of the bearing housing 1 for installing various components of the bearing housing 1; the frame includes an upper layer and a lower layer, with the motor and pressure detection device installed on the upper layer, and the oil pump, valve block, flow detection device and filter installed on the lower layer.
[0034] A filter 16 can be installed between the oil pump 12 and the bearing housing 1, i.e., before the lubricating oil enters the bearing housing 1 after exiting the oil pump outlet, to filter impurities in the lubricating oil and ensure its quality. In one specific embodiment, two filters 16 are configured, one in operation and one on standby, to ensure reliability. In long-term use, wear and tear on various components of the bearing housing 1 inevitably leads to the entry of lubricating oil. The filter 16 ensures the good quality of the lubricating oil and extends the service life of the components of the bearing housing 1.
[0035] A valve block can be installed in the lubrication system between the oil pump 12 and the bearing housing 1, after the lubricating oil exits from the oil pump outlet and before entering the bearing housing 1. This valve block controls the on / off state and flow rate of the lubricating oil in the oil pipe. The valve block can be installed in the oil pipe and includes: an overflow valve 14, a check valve 15, and a throttle valve 17. The check valve 15 is installed in the oil pipe from the oil pump 12 to the bearing housing 1, controlling the unidirectional flow of lubricating oil from the oil pump 12 to the bearing housing 1. The throttle valve 17 is installed in the oil pipe from the oil pump 12 to the bearing housing 1, controlling the flow rate of lubricating oil by changing the throttling cross-section or throttling length. The check valve 15 and the throttle valve 17 are connected in series in the oil pipe. The overflow valve 14 is designed at the outlet of the oil pump 12 to maintain a basically stable pressure in the lubrication system, serving a safety protection function. For example, the overflow valve 14 can be designed in the outlet oil line of the oil pump 12. When the lubrication system is operating normally, the relief valve 14 is closed. It only opens to release pressure when the lubrication system pressure exceeds the set pressure, preventing damage to components or other hazards caused by excessive pressure, such as preventing oil pipe rupture or damage to hydraulic actuators. When the lubrication system pressure drops to the set pressure, the relief valve 14 closes again. The design of the check valve 15, throttle valve 17, and relief valve 14 ensures adjustable and safe oil supply to the bearing housing 1, meeting process requirements and extending the equipment's service life.
[0036] The lubrication system also includes a detection device in the oil pipe for detecting pressure and flow. In one specific embodiment, the detection device is installed in the oil pipe after the lubricating oil exits the oil pump and before entering the bearing housing 1. The detection device in this application provides real-time safety data, facilitating maintenance and management. The detection device includes a pressure sensor and a flow sensor. The pressure sensor detects the pressure in the oil pipe, and the flow sensor detects the flow rate of the lubricating oil in the oil pipe. The installation of the pressure sensor and flow sensor allows users to observe pressure and flow data in real time, providing an additional layer of protection for personnel and equipment safety. In one specific embodiment, the flow rate of the oil pump 12 is generally 9 L / min, and the outlet pressure should not be less than 1.2 MPa. The lubricating oil is depressurized and enters the bearing at a pressure of 0.3 to 0.6 MPa.
[0037] The lubrication system is also equipped with a controller, which is electrically connected to the bearing housing 1, oil pump 12, valve block, and detection device, thereby controlling the operation of the bearing housing 1, oil pump 12, valve block, and detection device. The controller makes the bearing housing 1 more efficient and saves labor costs.
[0038] A replenishment hole is provided on the top plate of the bearing housing 1 for replenishing lubricating oil. Lubricating oil is replenished into the bearing housing 1 through the replenishment hole. The replenishment hole ensures that the bearing housing 1 is continuously replenished with lubricating oil, thus extending its service life.
[0039] The bearing housing contains a bearing bush, which is the component in a sliding bearing that directly contacts the journal. It has a semi-cylindrical, very smooth structure and is typically made of wear-resistant materials such as bronze or anti-friction alloys. As the core component of the bearing housing, the bearing bush supports the journal, reduces friction and wear between the journal and the supporting structure, and provides lubrication. The bearing bush has a bottom hole as an inlet for lubricating oil; both ends of the bearing bush connect to the oil collection grooves in the bearing housing, which in turn connect to the cavity. Specifically, lubricating oil enters the bearing bush through the bottom hole, overflows from both ends into the oil collection grooves, and then enters the cavity through the oil collection grooves.
[0040] In operation, lubricating oil enters oil pump 12 from cavity 11 through the oil pump inlet, and then from the oil pump outlet through the oil pipe to the valve block. The lubricating oil passes through the overflow valve 14 and check valve 15 in the valve block, then through the filter 16 and throttle valve 17, and is delivered to the bottom hole of the bearing bush 18 in the bearing housing 1, entering the bearing bush 18. The lubricating oil then enters the mating surface between the bearing bush 18 and the journal. Within the bearing housing 1, the lubricating oil at the mating surface between the bearing bush 18 and the journal creates pressure, lifting the journal and providing lubrication to the journal and bearing bush 18 as the main motor shaft rotates. Simultaneously, the lubricating oil flows from the mating surface to the oil collection groove in the bearing housing 1, and then enters the cavity 11 at the bottom of the bearing housing, completing one cycle of the lubrication system. If the oil pipe pressure is too high, the overflow valve 14 opens to release pressure, ensuring that the oil circuit pressure is safe, stable, and under control.
[0041] The bearing housing 1 is roughly a horizontal columnar structure. In the front view, the vertical cross-section is roughly circular with a radius of 1m, featuring a compact structure and complete functionality. Integrating the bearing housing 1 with the lubrication system, the oil station is positioned directly above the bearing housing 1, saving space and floor area, while also facilitating inspection and maintenance and reducing costs.
[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features of the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0043] For those skilled in the art, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. It is obvious that this invention is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, all embodiments are merely illustrative and not exhaustive, and should be considered exemplary and non-limiting. The scope of this invention is defined by the appended claims rather than the foregoing description, and therefore all changes falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims. All changes within the scope of this invention or its equivalents are included in this invention.
