Description

Technical Field

[0001] This utility model belongs to the technical field of reducing the temperature of sliding bearing pads, and particularly relates to a simple structure for reducing the temperature of sliding bearing pads. Background Technology

[0002] Currently, many older units use an immersion method for supplying oil to sliding bearings, where cooling oil enters from the bottom of the bearing mounting base, completely submerges the bearing and shaft, and then overflows from the top of the bearing mounting base.

[0003] This oil supply method generates significant churning heat, making it difficult to remove the hot oil in time. The incoming cold oil mixes with the hot oil, raising the inlet oil temperature and consequently increasing the bearing temperature. Over time, coking and carbonization occur on the bearing surface, exacerbating the temperature rise and damaging the bearing's performance, causing equipment downtime and production delays. Therefore, we propose a simple structure to reduce the temperature of sliding bearing bearing pads. Utility Model Content

[0004] The purpose of this invention is to provide a simple structure for reducing the temperature of sliding bearing pads, thereby solving the problems mentioned in the background art.

[0005] In view of this, the present invention provides a simple structure for reducing the temperature of sliding bearing pads, including an outer ring, a pad seat fixedly installed on the surface of the outer ring, an oil supply hole opened on the upper side of the pad seat, and a spring pin fixedly installed in the oil supply hole; The inner ring has multiple tiles fixedly installed on its upper side. A sealing ring is provided between the tile and the tile seat. An oil passage groove is opened on one side of the tile, and one end of the spring pin extends into the oil passage groove.

[0006] In this technical solution, a bearing seat is fixedly installed on the side of the outer ring facing the shaft. An oil supply hole is provided on the radially inner side of the bearing seat for lubricating oil supply. A spring pin, specifically a one-way valve structure with a spring-loaded plunger, is fixedly installed inside the oil supply hole. The inner ring serves as the rotating inner ring of the bearing, and multiple bearing pads are fixedly installed on the radially outer side of the inner ring. These bearing pads constitute the working surface of the bearing. O-rings are provided at the contact surfaces or gaps between the bearing pads and the bearing seat. An oil passage groove is provided on one side of the bearing pad. The oil outlet end of the spring pin extends and aligns with the oil passage groove on the bearing pad. Lubricating oil is pumped in from an external oil source and reaches the spring pin through the oil supply hole on the bearing seat. The spring pin acts as a throttling, pressure stabilizing, or one-way valve to ensure stable oil flow. After passing through the spring pin, the lubricating oil no longer fills the entire bearing cavity but is directly guided through its outlet to the specially designed oil passage groove on the surface of the bearing pad. The oil passage groove distributes the lubricating oil to the working surface of the bearing pad, forming a lubricating film and directly cooling the bearing pad. Because the lubricating oil does not submerge the entire bearing, but is precisely supplied to the working surfaces of the bearing pads that require lubrication and cooling, the amount of oil is greatly reduced, and heat generated by churning losses is almost eliminated. Used hot oil can be quickly drained from the bearing end or other drain holes, and will not accumulate in the cavity and mix with cold oil, thus significantly reducing the overall oil temperature and bearing pad temperature.

[0007] In the above technical solution, a bearing ball is further provided between the inner ring and the outer ring.

[0008] In this technical solution, the bearing balls roll within the raceways of the inner and outer rings, forming a bearing structure.

[0009] In the above technical solution, a mounting groove is further provided on one side of the inner ring, a lower adjusting block is fixedly installed in the mounting groove, and an upper adjusting block is fixedly installed on one side of the tile.

[0010] In this technical solution, an installation groove is provided on the end face or radial face of the inner ring. A lower adjusting block is fixedly installed in the installation groove. An upper adjusting block is fixedly installed on one side of the bearing. By grinding or replacing the upper and lower adjusting blocks of different thicknesses, the radial position of the bearing can be finely adjusted, thereby precisely controlling the clearance between the bearing and the journal and obtaining the optimal oil film thickness and load-bearing capacity.

[0011] In the above technical solution, an adjustment shim is further fixedly installed on the lower side of the tile base.

[0012] In this technical solution, the installation height of the entire bearing can be adjusted by increasing or decreasing the thickness of the shims, ensuring the alignment of the shaft system.

[0013] In the above technical solution, the sealing ring is further made of rubber.

[0014] In this technical solution, the rubber sealing ring is used to prevent lubricating oil from leaking from the mating surface between the bearing and the bearing seat, ensuring that the oil flows along the designed path.

[0015] In the above technical solution, the gap between the tile and the tile seat is further designed to be 1.5mm.

[0016] In this technical solution, the 1.5mm gap is optimized to ensure that the lubricating oil can pass smoothly to the cooling surface of the bearing without being too large, which would cause oil pressure loss or vibration.

[0017] In the above technical solution, the diameter of the sealing ring is 1.8mm.

[0018] In this technical solution, the 1.8mm wire diameter O-ring can provide a suitable sealing pressure after being compressed, effectively sealing the 1.5mm gap and preventing oil leakage.

[0019] The beneficial effects of this utility model are: This simple structure for reducing the temperature of sliding bearing pads introduces lubricating oil through an oil supply hole on the pad holder, and then guides the lubricating oil from the pad holder to an oil groove on the pad surface via a spring pin. To ensure that the lubricating oil is precisely guided to the pad surface without leakage, this structure has low modification costs and low oil consumption. It does not require the entire bearing to be submerged in lubricating oil; only each oil guide pipe needs to contain oil. Hot oil during operation can be quickly discharged, eliminating the need for specially designed sealing rings to prevent oil loss. This achieves the effect of rapidly reducing the temperature of the pads. Attached Figure Description

[0022] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0023] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0024] Example 1: This example provides a simple structure for reducing the temperature of sliding bearing pads, including an outer ring 3, a pad seat 5 fixedly installed on the surface of the outer ring 3, an oil supply hole on the upper side of the pad seat 5, and a spring pin 7 fixedly installed in the oil supply hole; The inner ring 1 has multiple tiles 2 fixedly installed on its upper side. A sealing ring 6 is provided between the tile 2 and the tile seat 5. An oil passage groove is opened on one side of the tile 2, and one end of the spring pin 7 extends into the oil passage groove.

[0025] The outer ring 3 has a bearing seat 5 fixedly installed on the side facing the shaft. An oil supply hole is provided on the radially inner side of the bearing seat 5 for lubricating oil supply. A spring pin 7, specifically a one-way valve structure with a spring-loaded plunger, is fixedly installed inside the oil supply hole. The inner ring 1 serves as the rotating inner ring of the bearing, and multiple bearing pads 2 are fixedly installed on the radially outer side of the inner ring 1. These bearing pads 2 constitute the working surface of the bearing. O-rings 6 are provided at the contact surface or gap between the bearing pads 2 and the bearing seat 5. An oil passage groove is provided on one side of the bearing pad 2. The oil outlet end of the spring pin 7 extends and aligns with the oil passage groove on the bearing pad 2. Lubricating oil is pumped in from an external oil source and reaches the spring pin 7 through the oil supply hole on the bearing seat 5. The spring pin 7 acts as a throttling, pressure stabilizing, or one-way valve to ensure stable oil flow. After passing through the spring pin 7, the lubricating oil no longer fills the entire bearing cavity but is directly guided through its outlet into the specially designed oil passage groove on the surface of the bearing pad 2. The oil channel distributes lubricating oil to the working surface of bearing pad 2, forming a lubricating film and directly cooling the pad 2. Because the lubricating oil does not submerge the entire bearing, but is precisely supplied to the working surfaces of bearing pad 2 that require lubrication and cooling, the amount of oil is greatly reduced, virtually eliminating heat loss due to churning. Used hot oil can be quickly drained from the bearing end or other drain holes, preventing it from accumulating in the cavity and mixing with cold oil, thus significantly reducing the overall oil temperature and the temperature of bearing pad 2.

[0026] Example 2: This example provides a simple structure for reducing the temperature of sliding bearing pads. In addition to the technical solutions of the above examples, it also has the following technical features: a bearing ball 4 is provided between the inner ring 1 and the outer ring 3.

[0029] An installation groove is provided on the end face or radial face of the inner ring 1. A lower adjusting block 10 is fixedly installed in the installation groove. An upper adjusting block 8 is fixedly installed on one side of the bearing 2. By grinding or replacing the upper and lower adjusting blocks 10 with different thicknesses, the radial position of the bearing 2 can be finely adjusted, thereby precisely controlling the clearance between the bearing 2 and the journal and obtaining the best oil film thickness and load-bearing capacity.

[0030] Example 4: This example provides a simple structure for reducing the temperature of sliding bearing pads. In addition to the technical solutions of the above examples, it also has the following technical features: an adjusting shim 9 is fixedly installed on the lower side of the pad 5.

[0031] The installation height of the entire bearing can be adjusted by increasing or decreasing the thickness of the shim 9 to ensure the alignment of the shaft system.

[0032] Example 5: This example provides a simple structure for reducing the temperature of sliding bearing pads. In addition to the technical solutions of the above examples, it also has the following technical features: the sealing ring 6 is made of rubber.

[0033] Among them, the rubber sealing ring 6 is used to prevent lubricating oil from leaking from the mating surface of the bearing block 2 and the bearing seat 5, ensuring that the oil flows along the designed path.

[0034] Example 6: This example provides a simple structure for reducing the temperature of sliding bearing pads. In addition to the technical solutions of the above examples, it also has the following technical features: the gap between the pad 2 and the pad seat 5 is designed to be 1.5mm.

[0035] The 1.5mm gap is optimized to ensure that the lubricating oil can pass smoothly to the cooling surface of the bearing 2 without being too large, which would cause oil pressure loss or vibration.

[0038] Working principle: When using the device, first install the entire device on the equipment by adjusting the shim 9, and then attach the device to the tile 2 at the position where it needs to be installed and use it. When cooling of the bearing 2 is required during use, lubricating oil is introduced through the oil supply hole on the bearing seat 5, and the lubricating oil is guided from the bearing seat 5 to the oil groove on the surface of the bearing 2 by the spring pin 7. In order to ensure that the lubricating oil can be accurately guided to the surface of the bearing 2 without spilling along the way, it plays a role in lubricating and cooling the bearing 2.
