Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, specifically to a bearing housing with stable performance. Background Technology

[0002] Bearing housings, as key components of numerous mechanical devices, are widely used in industrial production, transportation, energy, and many other fields. For example, in various motors, fans, machine tools, and rail vehicles, bearing housings play a vital role in supporting rotating shafts, reducing friction, bearing loads, and ensuring the smooth operation of rotating parts. Their performance directly affects the reliability, operating efficiency, and service life of the entire mechanical equipment.

[0003] In existing bearing housing lubrication methods, a common problem is the inability to effectively circulate the lubricating oil. Typically, bearing housing lubrication relies on the traditional method of periodically adding or replacing lubricating oil. Taking common industrial equipment as an example, operators must manually open the oil filler port on the housing to inject new lubricating oil according to a fixed maintenance cycle or based on experience, and drain the old oil through the drain port.

[0004] This traditional practice has many drawbacks. First, after a period of use, although some lubricating oil still has certain lubricating properties, its quality deteriorates due to the mixing of metal debris generated by wear inside the bearings and axle boxes. As a result, it is discharged and discarded, causing a large amount of lubricating oil to be wasted, increasing the operation and maintenance costs of the equipment and the potential pollution risk to the environment.

[0005] More importantly, the inability to recycle lubricating oil directly leads to the difficulty in maintaining stable performance of the bearing housing. Newly injected lubricating oil can effectively lubricate and cool the bearings and related components in the initial stage. However, as the equipment operates for longer periods, the amount of lubricating oil gradually decreases and its distribution becomes uneven. The inability to recycle and replenish the oil causes dry friction or insufficient lubrication to quickly occur in areas lacking lubrication, leading to an increased coefficient of friction and accelerated wear between components.

[0006] Increased friction and accelerated wear further triggered a series of chain reactions, seriously affecting the performance stability of the bearing housing. On the one hand, as a core component, excessive wear of the bearing will reduce its precision, such as increasing the clearance between the balls and raceways. This will not only generate abnormal vibration and noise, but also reduce the bearing's load-bearing capacity, making it more prone to fatigue failure under normal working loads and shortening the bearing's service life.

[0007] On the other hand, localized overheating due to poor lubrication inside the axle box also occurs frequently. Excessive temperature can alter the material properties of the axle box; for example, metal axle boxes may experience thermal deformation, affecting their fit with the bearing and further disrupting the stable operation of the entire bearing axle box. Moreover, in some equipment with high requirements for rotational precision, these performance instabilities caused by the inability to circulate lubricating oil can lead to a decrease in the overall working accuracy of the equipment, affecting product quality and potentially even causing safety accidents. Utility Model Content

[0008] To address the aforementioned problems, this invention presents a bearing housing with stable performance.

[0009] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0010] A high-performance bearing housing includes a housing body, a motor mounted on the left side wall of the housing body, an inlet pipe mounted on the right side wall of the housing body, an upper housing mounted on the top of the outer wall of the housing body, a lower housing mounted on the top wall of the upper housing, a top seat mounted on the outer wall of the lower housing, a filter screen mounted on the bottom of the outer wall of the housing body, a connecting seat mounted on the bottom wall of the filter screen, an oil tank mounted on the bottom wall of the connecting seat, an oil pump mounted on the left side wall of the oil tank, a drain pipe mounted on the output end of the oil pump, an auxiliary oil tank mounted on the top of the right side wall of the oil tank, a cap threadedly connected to the top wall of the auxiliary oil tank, a connecting pipe mounted on the bottom of the right side wall of the oil tank, and a filtration mechanism housed within the housing body.

[0011] Furthermore, the filtration mechanism includes a filter cylinder, a rotating rod on the left side wall of the filter cylinder, and a round rod on the right side wall of the filter cylinder. The outer walls of the rotating rod and the round rod are rotatably connected to the inner walls of the left and right sides of the housing through bearings. The left end of the rotating rod is fixedly connected to the output end of the motor through a coupling. A connecting rod is provided on the inner wall of the right side of the filter cylinder, and the outer wall of the connecting rod has multiple through holes communicating with the inner cavity.

[0012] Furthermore, the connecting rod, the round rod, and the liquid inlet pipe are connected in a continuous manner.

[0013] Furthermore, the through holes are arranged in a circumferentially spaced pattern on the outer wall of the connecting rod.

[0014] Furthermore, the outer ring of the bearing is fixedly connected to the inner wall of the housing through the bearing seat, and the inner ring of the bearing is interference-fitted with the outer wall of the rotating rod and the round rod.

[0015] The beneficial effects of this utility model are:

[0016] This invention establishes a circulation loop for lubricating oil between the axle box and the oil tank, utilizing oil pump delivery and filter cartridge filtration to achieve the recycling of lubricating oil. This avoids the unnecessary waste of a large amount of lubricating oil, effectively improves the utilization efficiency of lubricating oil, reduces equipment operation and maintenance costs, and minimizes potential environmental pollution risks.

[0017] This invention can continuously deliver filtered lubricating oil into the bearing housing via an oil pump to lubricate the bearing, ensuring that the bearing and related components always receive a sufficient and uniform supply of lubricating oil, maintaining a good lubrication condition, effectively reducing the coefficient of friction between components, and reducing wear.

[0018] The improved lubrication of this invention allows for more precise matching of key components such as the bearing balls and raceways, effectively preventing abnormal increases in clearance, maintaining high bearing precision, ensuring its load-bearing capacity, extending bearing service life, and ultimately enhancing the overall performance stability of the bearing housing.

[0019] This invention utilizes the characteristic of increasing the contact area between the lubricating oil and air during the rotation of the filter cartridge during the lubricating oil circulation process, thereby improving the heat dissipation effect. It can promptly remove the heat generated by the bearing operation, effectively preventing the axle box from overheating and avoiding adverse effects on the axle box material and fitting precision due to excessive temperature, thus ensuring the stable operation of the bearing axle box.

[0020] This invention ensures the stable performance of the bearing housing by realizing the effective circulation of lubricating oil, thereby helping to maintain the high-precision operation of the equipment as a whole, improving product quality, enhancing the safety and reliability of equipment operation, and meeting the needs of various mechanical equipment with high working precision requirements.

[0021] By setting a connecting rod with multiple through holes and a rotatable filter cartridge in the circulation system, the lubricating oil carrying impurities can be filtered quickly and efficiently by the rotation of the filter cartridge. This effectively removes impurities such as metal shavings, ensuring the cleanliness of the circulating lubricating oil, further improving lubrication quality, and preventing impurities from causing wear and damage to bearings and axle boxes.

[0029] Furthermore, the filtration mechanism includes a filter cylinder 15, a rotating rod 16 on the left side wall of the filter cylinder 15, and a round rod 17 on the right side wall of the filter cylinder 15. The outer walls of the rotating rod 16 and the round rod 17 are rotatably connected to the inner walls of the left and right sides of the housing 1 through bearings. The left end of the rotating rod 16 is fixedly connected to the output end of the motor 2 through a coupling. A connecting rod 18 is provided on the inner right side wall of the filter cylinder 15. The outer wall of the connecting rod 18 has multiple through holes 19 communicating with the inner cavity.

[0030] Furthermore, the connecting rod 18, the round rod 17, and the liquid inlet pipe 3 are connected.

[0031] Furthermore, the through holes 19 are arranged in a circumferentially spaced pattern on the outer wall of the connecting rod 18.

[0032] Furthermore, the outer ring of the bearing is fixedly connected to the inner wall of the housing 1 through the bearing seat, and the inner ring of the bearing is interference-fitted with the outer walls of the rotating rod 16 and the round rod 17.

[0033] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0034] One specific application of this embodiment is:

[0035] When in use, connect the other end of the inlet pipe 3 to the oil drain port of the shaft box, connect the other end of the drain pipe 11 to the oil filling port of the shaft box, rotate and remove the cover 13, inject the lubricating oil into the auxiliary oil tank 12 and the oil tank 9, and tighten the cover 13.

[0036] After the oil pump 10 is started, the lubricating oil in the oil tank 9 is transported into the bearing box through the drain pipe 11 to lubricate the bearing. The lubricating oil carries the temperature generated during the operation of the bearing and impurities such as metal shavings into the connecting rod 18 through the inlet pipe 3 and the round rod 17, and flows out into the filter cartridge 15 through the through hole 19.

The motor 2 causes the rotating rod 16 to drive the filter cartridge 15, the round rod 17 and the connecting rod 18 to rotate. The rotation of the filter cartridge 15 performs a rapid filtration operation on the lubricating oil. The filtered lubricating oil falls downward through the connecting seat 8 into the oil tank 9, realizing the filtration and recycling of the lubricating oil. The heat in the housing 1 can be discharged through the top seat 6.
