Description

Technical Field

[0001] The present invention relates to the field of sliding bearing equipment, and in particular to a split-type combined structure low-noise sliding bearing and a method. Background Art

[0002] In the field of mechanical transmission, sliding bearings are widely used in various rotating equipment due to their advantages such as simple structure and strong load-bearing capacity. However, in actual operation, traditional sliding bearings often suffer from problems such as insufficient lubrication and poor heat dissipation, resulting in less than ideal friction between the shaft and the bearing. On the one hand, the lubricating oil cannot evenly cover the friction surface, resulting in frequent localized dry friction. On the other hand, the heat generated by high-load operation cannot be dissipated in time, causing the lubricating oil viscosity to decrease, further weakening the lubrication effect. These factors intensify the friction between the shaft and the bearing, causing strong vibration and generating loud noise, which not only seriously affects the comfort of the working environment, but also accelerates bearing wear, shortens the service life of the equipment, and may even cause equipment failure. In addition, traditional bearings lack an effective lubricating oil circulation and recovery mechanism, and the disordered loss of lubricating oil further exacerbates the poor lubrication condition. Therefore, we propose a split-type combined structure low-noise sliding bearing and method to address the above-mentioned problems. Summary of the Invention

[0009] Preferably, the end of the rotating shaft passes through the base and the front end of the guide bin, and the rotating shaft is rotatably connected to the base and the guide bin.

[0010] Preferably, the end of the second connecting pipe away from the guide chamber passes through the rear portion of the base, and a one-way valve is installed on the side of the second connecting pipe close to the guide chamber.

[0011] Preferably, the front and rear parts of the outer peripheries of the upper bearing shell and the lower bearing shell are fixedly connected to limit seats, and a one-way valve is installed inside the through hole on the lower bearing shell.

[0012] Preferably, both inner sides of the upper bearing shell and the lower bearing shell are provided with symmetrical distribution slots and a plurality of guide slots, the guide slots are connected to each other through the distribution slots, and the distribution slots are connected to the through holes.

[0013] Preferably, the front and rear parts of the guide slot are connected with a plurality of connecting channels, and the front and rear parts of the inner sides of the upper bearing and the lower bearing are provided with return grooves, and the return grooves are connected with the inside of the guide slot through the connecting channels.

[0015] Preferably, fixing bolts are passed through both sides of the middle of the top seat and the base, and the fixing bolts are used to fix the top seat and the base. Evenly distributed openings are opened in the middle of the front and rear sides of the top seat and the base.

[0016] Preferably, a method for using a split-type combined structure low-noise sliding bearing comprises the following steps:

[0017] S1. Equipment Installation

[0018] S1.1. Preparation: Check all parts of the split sliding bearing to ensure that the fixing bolts, upper bearing, lower bearing, top seat, base, limit seat and other parts are not damaged or deformed. Clean the surface of each part to remove oil and impurities.

[0019] S1.2. Drive shaft installation: Loosen the fixing bolts and smoothly guide the equipment drive shaft between the upper and lower bearing shells; adjust the position of the drive shaft so that it is in the center of the bearing shell to ensure installation accuracy;

[0020] S1.3. Assemble and secure the bearings: Align the upper and lower bearings so that the limit seats correspond to the bayonet holes in the middle of the top and base seats, respectively. Place the top seat on top of the upper bearing and tighten the fixing bolts to the specified torque using a tool to limit and stabilize the upper and lower bearings.

[0021] S1.4, Impeller connection: Use the installation key to reliably connect and install the equipment drive shaft with the front impeller and rear impeller, ensuring that the connection is tight and not loose;

[0022] S2, lubrication realization

[0023] S2.1. Lubricating oil introduction: The lubricating oil flows into the through hole on the upper bearing shell through the conduit on the top seat;

[0024] S2.2, Lubricating oil diffusion: The lubricating oil enters the arc-shaped distribution slot on the inner side of the upper bearing to achieve diffusion and diversion, and then enters the guide slot and is evenly distributed between the equipment drive shaft and the upper and lower bearings, reducing friction among the three.

[0025] S2.3, Lubricating oil return: The return grooves on the front and rear sides of the distribution slots and the guide slots intercept the escaped lubricating oil. Since the return grooves are designed from shallow to deep from the outside to the inside, the accumulated lubricating oil flows back to the inside of the guide slots and the distribution slots under the action of gravity, reducing the escape and loss of lubricating oil;

[0026] S3. Cooling guarantee

[0027] S3.1. When the equipment drive shaft rotates, it drives the front and rear impellers to rotate synchronously. The impellers disturb the surrounding airflow through the guide ports on the upper part, thereby cooling the drive shaft, bearings, and the lubricating oil inside the split sliding bearings, preventing the equipment from overheating and causing changes in the physical properties of the materials.

[0028] S4, lubricating oil circulation

[0029] S4.1. Power Generation: When the front impeller rotates, the outer ring gear drives the meshing gear column at the bottom to rotate synchronously, which in turn drives the coaxial half gear to rotate;

[0030] S4.2, carriage movement: The half gears continuously mesh with the racks on the fixed frames on both sides, driving the carriage to perform continuous piston motion inside the guide chamber;

[0031] S4.3. Lubricating oil circulation: Under the action of the one-way valves inside the lower bearing shell and connecting pipe 2, the slide draws the lubricating oil from the upper and lower bearing shells during each suction and expulsion process. The oil enters the upper part of the guide chamber, is then introduced into connecting pipe 2 and the annular pipe, and finally flows back into the top seat through connecting pipe 1, thus achieving lubricating oil circulation. At the same time, the movement of the slide provides driving force for the subsequent addition of lubricating oil, promoting its diffusion.

[0032] S4.4. Circulation heat dissipation: The ring pipe is installed between the reserved openings of the rear impeller. The airflow disturbed by the rotation of the rear impeller dissipates heat to the ring pipe, ensuring the stability of the lubricating oil circulation.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] The present invention connects the equipment drive shaft with the front and rear impellers through a split combined structure. When the impeller rotates, the guide port is used to disturb the airflow to cool the drive shaft, bearing and lubricating oil, avoiding abnormal noise caused by component deformation and increased friction due to overheating, ensuring stable operation of the equipment and extending its service life.

[0035] The present invention uses a unique lubricating oil delivery path to allow the lubricating oil to enter the outward-expanding arc-shaped distribution slot through the conduit and through-hole and then evenly diffuse to the guide slot, fully lubricating the drive shaft and the upper and lower bearings, significantly reducing friction between components, reducing vibration and noise caused by friction, and providing a quiet and stable environment for long-term high-speed operation of the equipment.

[0036] The present invention effectively intercepts the escaped lubricating oil through the reflux grooves on the front and rear sides of the distribution slots and the guide slots. Its special shallow to deep design promotes the reflux of lubricating oil, reduces the dry friction noise caused by lubricating oil loss, maintains a good lubrication state, and ensures quiet and long-lasting operation of the equipment.

[0037] The present invention uses a gear ring-gear column-half gear-rack transmission mechanism driven by a front impeller to drive the slide to perform piston movement in the guide chamber to realize lubricating oil circulation. On the one hand, this circulation system avoids abnormal disturbance noise caused by disordered diffusion of lubricating oil. On the other hand, it provides a driving force for the newly added lubricating oil, accelerates its diffusion, further improves the lubrication effect, and reduces friction noise. At the same time, the heat dissipation effect on the ring pipe when the rear impeller rotates ensures the stability of lubricating oil performance and reduces lubrication failure and noise problems caused by oil temperature changes.

DETAILED DESCRIPTION

[0046] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0047] like Figure 1-Figure 7 A split-type combined structure low-noise sliding bearing shown in FIG. 1 includes a split sliding bearing 1, which includes a top seat 101 and a base 102. An upper bearing shell 109 and a lower bearing shell 110 are provided on the inner sides of the top seat 101 and the base 102. Fixing bolts 103 penetrate both sides of the middle of the top seat 101 and the base 102. The fixing bolts 103 are used to fix the top seat 101 and the base 102. Evenly distributed openings 106 are provided in the middle of the front and rear sides of the top seat 101 and the base 102. Lubricating oil diffusion assemblies are installed in the top seat 101 and the base 102. Lubricating oil cooling assemblies are provided on the front and rear sides of the upper bearing shell 109 and the lower bearing shell 110.

[0048] Furthermore, in the specific implementation, people can ensure the stable rotation of the driving shaft of the working equipment through the split sliding bearing 1. In actual use, people can first loosen the fixing bolt 103, and then guide the driving shaft of the equipment to be installed between the upper bearing 109 and the lower bearing 110, and then align the upper bearing 109 and the lower bearing 110, and place the top seat 101 on the top of the upper bearing 109. The limiting seats 118 set on the front and rear sides of the outer periphery of the upper bearing 109 and the lower bearing 110 can correspond to the snap-fits in the middle of the top seat 101 and the base 102 respectively, and then tighten the fixing bolt 103 to achieve the limitation and stable fixation of the upper bearing 109 and the lower bearing 110.

[0049] The lubricating oil diffusion component is used to quickly diffuse the lubricating oil;

[0050] The lubricating oil cooling assembly is used for rapid circulation cooling of the lubricating oil;

[0051] The lubricating oil diffusion assembly includes a guide bin 121, which is mounted in the middle of the base 102. A slide 125 is slidably connected to the guide bin 121. Fixed frames 124 are mounted on both sides of the middle of the slide 125. The middle of each side of the fixed frame 124 is fixedly connected to a rack 122. A rotating shaft 120 is provided between the fixed frames 124. The front end of the rotating shaft 120 is fixedly connected to a gear column 119. The rear side of the middle of the outer periphery of the rotating shaft 120 is fixedly connected to a half gear 123. The half gear 123 is used to mesh with the racks 122 on both sides. A second connecting pipe 107 is fixedly connected to the upper rear portion of the outer periphery of 121. The end of the second connecting pipe 107 away from the guide chamber 121 is fixedly connected to the ring pipe 116. The top of the ring pipe 116 is connected to the first connecting pipe 104 via a rotary joint 115. The end of the first connecting pipe 104 away from the ring pipe 116 is installed on the top of the top seat 101. A guide tube 117 is fixedly connected to the middle of the side close to the top seat 101 and the base 102. A through hole 128 is passed through the middle of the upper bearing shell 109 and the lower bearing shell 110. The guide tubes 117 are both engaged inside the through hole 128.

[0052] Furthermore, in the specific implementation, when in the working state, when the front impeller 105 rotates, it will drive the meshing tooth column 119 at the bottom to rotate synchronously through the outer peripheral gear ring 111, and the coaxial half gear 123 can be driven to rotate synchronously through the gear column 119. When the half gear 123 is driven, it will continuously mesh with the racks 122 on the fixed frames 124 on both sides, thereby driving the slide 125 as a whole to continuously rise and fall through the fixed frames 124. During the lifting process of the slide 125, continuous piston movement will be performed inside the guide chamber 121. Under the action of the one-way valve inside the lower bearing shell 110 and the connecting pipe 107, the lubricating oil inside the upper bearing shell 109 and the lower bearing shell 110 will be extracted during each suction and exhalation process, so that it will enter the upper part of the guide chamber 121, and then this part of the lubricating oil will be introduced into the connecting pipe 107. Under the guidance of the connecting pipe 107, the lubricating oil will further enter To the inside of the annular tube 116, under the continuous piston movement of the slide 125, the continuously entering lubricating oil will flow back to the top seat 101 through the connecting pipe 104 to realize the circulation of the lubricating oil. Through continuous suction and reflux, the disorderly diffusion of the lubricating oil can be further avoided, and the lubricating oil can be restrained, thereby ensuring the lubrication work between the equipment drive shaft and the upper bearing 109 and the lower bearing 110. At the same time, under the continuous working state of the slide 125, a continuous driving force will be given to the subsequently replenished lubricating oil, which can be beneficial to the diffusion of the lubricating oil when it just enters the equipment drive shaft and the upper bearing 109 and the lower bearing 110. During this process, the annular tube 116 is installed between the reserved openings 112 on the rear impeller 108. When the rear impeller 108 rotates, the disturbed airflow during the rotation of the rear impeller 108 will continue to fully dissipate the heat of the annular tube 116, which is beneficial to actual use.

[0053] Among them, the lubricating oil cooling assembly includes a front impeller 105 and a rear impeller 108, and a rotating ring 114 is fixedly connected to the middle part of the side close to the front impeller 105 and the rear impeller 108. The front impeller 105 is rotatably connected to the front part of the upper bearing 109 and the lower bearing 110 through the rotating ring 114, and the rear impeller 108 is rotatably connected to the rear part of the upper bearing 109 and the lower bearing 110 through the rotating ring 114. The outer periphery of the front impeller 105 and the rear impeller 108 are both provided with uniformly distributed guide ports 113, and the guide ports 113 are all set to an inclined state. A gear ring 111 is fixedly connected to the middle part of the outer periphery of the front impeller 105, and the bottom of the gear ring 111 is meshed with a gear column 119. A reserved opening 112 is opened on the outer periphery of the rear impeller 108, and an annular pipe 116 is arranged inside the reserved opening 112, and the annular pipe 116 is not in direct contact with the rear impeller 108;

[0054] Furthermore, in a specific implementation, when the device drive shaft is installed, the device drive shaft can be connected and installed with the front impeller 105 and the rear impeller 108 through the installation key, so that when the device drive shaft is working and rotating, the front impeller 105 and the rear impeller 108 will rotate synchronously. When the front impeller 105 and the rear impeller 108 rotate, the guide port 113 opened at the top will disturb the surrounding airflow, thereby cooling the drive shaft and the upper and lower bearings 109 and 110 as well as the internal lubricating oil of the split sliding bearing 1, avoiding changes in the physical properties of the material due to overheating of the equipment, which is beneficial to actual use.

[0055] Among them, the end of the rotating shaft 120 passes through the base 102 and the front end of the guide warehouse 121, the rotating shaft 120 is rotatably connected to the base 102 and the guide warehouse 121, the end of the connecting pipe 107 away from the guide warehouse 121 passes through the rear part of the base 102, and a one-way valve is installed on the side of the connecting pipe 107 close to the guide warehouse 121. The front and rear parts of the outer periphery of the upper bearing 109 and the lower bearing 110 are fixedly connected to the limited seat 118, and the through hole 128 on the lower bearing 110 is internally installed with a one-way valve. Symmetrical distribution slots 129 and multiple guide slots 127 are provided on the inner sides of both the upper bearing 109 and the lower bearing 110. The guide slots 127 are connected to each other through the distribution slots 129. The distribution slots 129 are connected to the through holes 128. The front and rear parts of the guide slots 127 are connected to multiple connecting channels 126. The front and rear parts of the inner sides of the upper bearing 109 and the lower bearing 110 are both provided with return grooves 130. The return grooves 130 are connected to the inside of the guide slots 127 through the connecting channels 126.

[0056] Furthermore, in a specific implementation, the lubricating oil will enter the through hole 128 on the upper bearing 109 through the conduit 117 on the top seat 101, so that the lubricating oil can further enter the distribution slot 129 on the inner side of the upper bearing 109. The distribution slot 129 with an outward arc design can diffuse the lubricating oil, so that the lubricating oil will be diverted to the inside of the guide slot 127, so that the lubricating oil will be evenly distributed between the equipment drive shaft and the upper bearing 109 and the lower bearing 110, thereby achieving lubrication between the three, and can greatly reduce the friction between the equipment drive shaft and the upper bearing 109 and the lower bearing 110, which is beneficial to the equipment drive. The shaft rotates at high speed for a long time. During this process, the reflux grooves 130 on the front and rear sides of the distribution grooves 129 and the guide grooves 127 can intercept the lubricating oil escaping between the equipment drive shaft and the upper bearing 109 and the lower bearing 110, thereby preventing the lubricating oil from escaping too much. The reflux grooves 130 are all designed from shallow to deep from the outside to the inside, so that the lubricating oil accumulated inside the reflux grooves 130 will flow back to the guide grooves 127 and the distribution grooves 129 under the action of gravity, realizing the restraint and reflux of the lubricating oil, thereby effectively reducing the escape and loss of the lubricating oil, which is conducive to maintaining a good working condition for a long time.

[0057] Among them, a method for using a split-type combined structure low-noise sliding bearing includes the following steps:

[0058] S1. Equipment Installation

[0059] S1.1. Preparation: Check all parts of the split sliding bearing to ensure that the fixing bolts 103, upper bearing 109, lower bearing 110, top seat 101, base 102, limit seat 118 and other parts are not damaged or deformed. Clean the surface of each part to remove oil stains and impurities.

[0060] S1.2. Drive shaft installation: Loosen the fixing bolts 103 and smoothly guide the equipment drive shaft between the upper bearing 109 and the lower bearing 110; adjust the position of the drive shaft so that it is in the center of the bearing to ensure installation accuracy;

[0061] S1.3. Assemble and secure the bearings: Align the upper bearing 109 with the lower bearing 110, aligning the position-limiting seat 118 with the bayonet openings in the middle of the top seat 101 and the base 102, respectively. Place the top seat 101 on top of the upper bearing 109, and tighten the fixing bolts 103 to the specified torque using a tool to limit and stabilize the upper and lower bearings 109 and 110.

[0062] S1.4, Impeller connection: Use the installation key to reliably connect and install the equipment drive shaft with the front impeller 105 and the rear impeller 108, ensuring that the connection is tight and there is no looseness;

[0063] S2, lubrication realization

[0064] S2.1. Lubricating oil introduction: The lubricating oil flows through the conduit 117 on the top seat 101 and into the through hole 128 on the upper bearing shell 109;

[0065] S2.2. Lubricating oil diffusion: The lubricating oil enters the arc-shaped distribution slot 129 on the inner side of the upper bearing 109 to achieve diffusion and diversion. It then enters the guide slot 127 and is evenly distributed between the equipment drive shaft, the upper bearing 109, and the lower bearing 110, thereby reducing friction between the three.

[0066] S2.3. Lubricating oil return: Reflux grooves 130 on the front and rear sides of the distribution slots 129 and the guide slots 127 intercept escaping lubricating oil. Since the reflux grooves 130 are designed from shallow to deep from the outside to the inside, the accumulated lubricating oil flows back into the guide slots 127 and the distribution slots 129 under the action of gravity, reducing the escape and loss of lubricating oil.

[0067] S3. Cooling guarantee

[0068] S3.1. When the drive shaft of the equipment rotates, it drives the front impeller 105 and the rear impeller 108 to rotate synchronously. The impellers disturb the surrounding airflow through the guide port 113 on the upper portion, thereby cooling the drive shaft, bearing, and the lubricating oil inside the split sliding bearing, preventing the equipment from overheating and causing changes in the physical properties of the material.

[0069] S4, lubricating oil circulation

[0070] S4.1. Power Generation: When the front impeller 105 rotates, the outer gear ring 111 drives the meshing gear column 119 at the bottom to rotate synchronously, thereby driving the coaxial half gear 123 to rotate;

[0071] S4.2, carriage movement: The half gear 123 continuously meshes with the racks 122 on the fixed frames 124 on both sides, driving the carriage 125 to perform continuous piston motion inside the guide chamber 121;

[0072] S4.3. Lubricating Oil Circulation: Under the action of the one-way valves inside the lower bearing shell 110 and the second connecting pipe 107, the carriage 125 draws the lubricating oil from the upper and lower bearing shells 109 and 110 during each pumping and pushing process. The oil enters the upper portion of the guide chamber 121, is then introduced into the second connecting pipe 107 and the annular pipe 116, and finally flows back into the top seat 101 through the first connecting pipe 104, thus completing the circulation of the lubricating oil. Simultaneously, the movement of the carriage 125 provides a driving force for the subsequent replenishment of lubricating oil, promoting its diffusion.

[0073] S4.4. Circulation heat dissipation: The annular pipe 116 is installed between the reserved openings 112 of the rear impeller 108. The airflow disturbed by the rotation of the rear impeller 108 dissipates heat from the annular pipe 116, ensuring the stability of the lubricating oil circulation.

[0074] Working principle:

[0075] In actual use, people can ensure the stable rotation of the driving shaft of the working equipment through the split sliding bearing 1. In actual use, people can first loosen the fixing bolt 103, and then guide the driving shaft of the equipment to be installed between the upper bearing 109 and the lower bearing 110, and then align the upper bearing 109 and the lower bearing 110, and place the top seat 101 on the top of the upper bearing 109. The limiting seats 118 set on the front and rear sides of the outer periphery of the upper bearing 109 and the lower bearing 110 can correspond to the bayonet in the middle of the top seat 101 and the base 102 respectively, and then tighten the fixing bolt 103 to achieve the limitation and stable fixation of the upper bearing 109 and the lower bearing 110. When the equipment driving shaft is installed, the equipment driving shaft can be fixed by the installation key. It is connected and installed with the front impeller 105 and the rear impeller 108, so that when the driving shaft of the equipment is working and rotating, the front impeller 105 and the rear impeller 108 will rotate synchronously. When the front impeller 105 and the rear impeller 108 rotate, the air flow around them will be disturbed through the guide port 113 opened on the upper part, so as to realize the cooling of the driving shaft, the upper bearing 109, the lower bearing 110 and the internal lubricating oil of the split sliding bearing 1, and avoid the change of the physical properties of the material caused by overheating of the equipment, which is beneficial to actual use. The lubricating oil will enter the through hole 128 on the upper bearing 109 through the conduit 117 on the top seat 101, so that the lubricating oil can further enter the distribution slot 129 on the inner side of the upper bearing 109, and the distribution slot with an outward-expanding arc design The opening 129 can diffuse the lubricating oil so that the lubricating oil will be diverted to the inside of the guide groove 127, so that the lubricating oil will be evenly distributed between the equipment drive shaft and the upper bearing 109 and the lower bearing 110, thereby achieving lubrication between the three, and can greatly reduce the friction between the equipment drive shaft and the upper bearing 109 and the lower bearing 110, which is beneficial to the long-term high-speed rotation of the equipment drive shaft. In this process, the lubricating oil escaping between the equipment drive shaft and the upper bearing 109 and the lower bearing 110 can be intercepted by the reflux grooves 130 on the front and rear sides of the distribution groove 129 and the guide groove 127, thereby avoiding excessive escaping of the lubricating oil. The reflux grooves 130 are all set to be designed from shallow to deep from outside to inside, so that the lubricating oil accumulated in the reflux grooves 130 is not too much. 0The lubricating oil inside will flow back to the guide slot 127 and the distribution slot 129 under the action of gravity, realizing the confinement and reflux of the lubricating oil, thereby effectively reducing the escape and loss of the lubricating oil, and facilitating maintaining a good working condition for a long time. In the working state, when the front impeller 105 rotates, the outer peripheral gear ring 111 will drive the meshing tooth column 119 at the bottom to rotate synchronously, and the tooth column 119 can drive the coaxial half gear 123 to rotate synchronously. When the half gear 123 is driven, it will continuously mesh with the racks 122 on the fixed frames 124 on both sides, thereby driving the slide 125 as a whole to continuously rise and fall through the fixed frames 124. During the lifting process of the slide 125, continuous piston motion will be performed inside the guide chamber 121.Under the action of the one-way valve inside the lower bearing 110 and the connecting pipe 107, the lubricating oil inside the upper bearing 109 and the lower bearing 110 will be extracted during each suction and expulsion process, and enter the upper part of the guide chamber 121. Then, this part of the lubricating oil will be introduced into the connecting pipe 107. Under the guidance of the connecting pipe 107, the lubricating oil will further enter the annular tube 116. Under the continuous piston movement of the slide 125, the continuously entering lubricating oil will flow back to the top seat 101 through the connecting pipe 104 to realize the circulation of the lubricating oil. The continuous suction and reflux can further avoid the disordered diffusion of the lubricating oil, and realize The lubricating oil is constrained, thereby ensuring lubrication between the equipment drive shaft and the upper and lower bearings 109 and 110. At the same time, when the slide 125 is in continuous operation, it provides a continuous driving force for the subsequent lubricating oil, which is conducive to the diffusion of the lubricating oil when it first enters the equipment drive shaft and the upper and lower bearings 109 and 110. During this process, the annular pipe 116 is installed between the reserved openings 112 on the rear impeller 108. When the rear impeller 108 rotates, the disturbed airflow during the rotation of the rear impeller 108 will continue to fully dissipate heat from the annular pipe 116, which is beneficial for practical use.
