Description

Technical Field

[0001] This utility model relates to the field of fluid machinery technology, and in particular to a deep groove ball bearing. Background Technology

[0002] Mechanical parts are the basic components of machinery, and are inseparable individual parts that make up machines. Mechanical parts are both a discipline that studies and designs the basic mechanical components in various equipment, and a general term for parts and components. Among them, bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical bodies, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. There are various types of bearings, among which deep groove ball bearings, formerly known as radial ball bearings, are the most widely used type of rolling bearing. Their characteristics include low frictional resistance and high speed. They can be used in components that bear radial loads or combined radial and axial loads, as well as components that bear axial loads, such as small-power electric motors, automotive and tractor gearboxes, machine tool gearboxes, and general machines and tools. They have a wide range of applications in practical situations, hence the particular need for deep groove ball bearings.

[0003] Because most existing deep groove ball bearings rely on a single sealing structure for dust prevention during use, the seals are prone to aging and deformation during long-term high-speed operation. This leads to lubricant leakage and the intrusion of external impurities, thus accelerating wear on the bearing raceways. Therefore, traditional lubrication methods often involve periodic manual grease injection. However, this makes it difficult to achieve uniform lubricant distribution, easily causing localized dry friction between the rollers and the cage, severely impacting the bearing's service life.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: a deep groove ball bearing, including a bearing body 1, a sealing mechanism 2 provided on the inner wall of the bearing body 1, and a lubrication mechanism 3 provided on the outer wall of the bearing body 1. The sealing mechanism 2 includes a fixed housing 21, a sealing ring 22, a connecting block 23, a limiting block 24, and a fixing block 25. The fixed housing 21 is provided on the outer wall of the bearing body 1. The sealing ring 22 is installed inside the fixed housing 21. The connecting block 23 is installed inside the fixed housing 21. The limiting block 24 is provided inside the fixed housing 21. The fixing block 25 is provided on the wall of the limiting block 24. The connecting block 25 is installed on the outer wall of the fixing block 24. Through the arrangement of the fixed housing 21, sealing ring 22, connecting block 23, limiting block 24, and fixing block 25... First, the fixed housing 21 is installed on the outer wall of the bearing body 1. Then, the sealing ring 22 is installed inside the fixed housing 21. Next, the connecting block 23 is installed inside the fixed housing 21, and the limiting block 24 is installed inside the fixed housing 21. A fixing block 25 is provided on the wall of the limiting block 24, and a connecting block 25 is installed on the outer wall of the fixing block 24. Through the cooperation of the fixing block 25 and the connecting block 23, the limiting block 24 is fixed inside the fixed housing 21, thereby achieving multiple fixation of the sealing ring 22, improving the sealing effect, and thus enhancing the bearing capacity. The connection stability between the bearing body 1 and the sealing mechanism 2 prevents the sealing ring 22 from aging and deforming during long-term high-speed operation, effectively preventing lubricant leakage and external impurities from entering, thereby slowing down bearing raceway wear and improving bearing service life. The installation of the fixing shell 21 fixes the sealing ring 22, preventing it from falling off during long-term use. The sealing ring 22 improves the sealing performance of the bearing body 1, preventing external impurities from entering the interior of the bearing body 1 and damaging its internal parts. The connecting block 23 connects the limiting block 24, preventing it from falling off. The limiting block 24 limits the fixing block 25, preventing it from shaking during use and improving its stability. The fixing block 25 fixes the connecting block 23, further improving its stability and thus enhancing the overall stability.

[0018] Furthermore, the lubrication mechanism 3 includes a grease block 31, a fixing post 32, an oil spray nozzle 33, and a flow-limiting net 34. A grease block 31 and a fixing post 32 are provided on the outer wall of the bearing body 1. An oil spray nozzle 33 is provided on the protective shell 31, and a flow-limiting net 34 is installed inside the oil spray nozzle 33. Through the arrangement of the grease block 31, the fixing post 32, the oil spray nozzle 33, and the flow-limiting net 34, the grease block 31 stores lubricant. During the operation of the bearing body 1, the lubricant can be evenly distributed to various parts of the bearing body 1 through the oil spray nozzle 33, achieving the desired lubrication effect. The uniform lubrication of the bearing body 1 avoids local dry friction and improves the service life of the bearing body 1. The setting of the fixing column 32 plays a role in fixing the grease block 31, preventing the grease block 31 from falling off during use and improving the overall stability. The setting of the oil spray nozzle 33 realizes the uniform spraying of lubricant, avoids the waste of lubricant, and improves the utilization rate of lubricant. The setting of the flow limiting net 34 plays a role in limiting the flow of lubricant sprayed from the oil spray nozzle 33, preventing the excessive amount of lubricant sprayed, and further improving the utilization rate of lubricant.

[0019] Furthermore, the inner wall size of the sealing ring 22 matches the outer wall size of the fixed shell 21, and the outer wall size of the sealing ring 22 matches the inner wall size of the connecting block 23. By setting the sealing ring 22, the sealing ring 22 can fit tightly against the fixed shell 21 and the connecting block 23, which enhances the sealing effect, prevents lubricant leakage and external impurities from entering the bearing body 1, and further improves the service life of the bearing.

[0020] Furthermore, sealing rings 22 are provided on the outer walls of the connecting block 23, the limiting block 24, and the fixing block 25. The outer wall size of the fixing shell 21 matches the inner wall size of the limiting block 24. The limiting block 24 plays a limiting role in fixing the fixing shell 21, enhancing the stability of the fixing shell 21, preventing the fixing shell 21 from shaking during use, and further improving the overall stability.

[0021] Furthermore, the outer wall size of the fixing block 25 matches the inner wall size of the limiting block 24, and the outer wall size of the limiting block 24 matches the inner wall size of the connecting block 23. By setting the fixing block 25, the connection between the components becomes tighter, improving the overall sealing and stability, avoiding leakage or loosening during use, thereby further improving the service life and performance of the bearing.

[0022] Furthermore, three sealing rings 22 are provided, which are respectively set between the fixed shell 21 and the bearing body 1. The fixed shell 21 enhances the sealing effect of the sealing rings 22, further preventing lubricant leakage and external impurities from entering the bearing body 1, ensuring the normal operation of the bearing and extending its service life.

[0023] Furthermore, four grease blocks 31 are provided, which are symmetrically arranged around the central axis of the bearing body 1. By setting the grease blocks 31, more lubricant can be stored, ensuring the lubrication needs of the bearing body 1 during long-term operation, avoiding local dry friction caused by insufficient lubricant, and further improving the service life and stability of the bearing.

[0024] Furthermore, the fixing column 32 is symmetrically arranged with respect to the central axis of the bearing body 1, and the position of the oil spray nozzle 33 corresponds one-to-one with the position of the fixing column 32. Through the arrangement of the oil spray nozzle 33, the lubricant can be evenly sprayed to all parts of the bearing body 1, ensuring the uniform distribution of the lubricant and improving the lubrication effect. At the same time, through the arrangement of the flow limiting net 34, the flow of lubricant sprayed from the oil spray nozzle 33 is limited, avoiding waste caused by excessive lubricant spraying, further improving the utilization rate of lubricant and the service life of the bearing.

[0025] Working Principle: In use, the bearing body 1 is first installed in the mechanical equipment. When the bearing body 1 starts to operate, the grease block 31 in the lubrication mechanism 3 begins to release lubricant. The lubricant is evenly distributed to various parts of the bearing body 1 through the oil spray nozzle 33, achieving uniform lubrication of the bearing body 1, avoiding localized dry friction, and improving the service life of the bearing body 1. Simultaneously, the flow-limiting net 34 limits the flow of lubricant sprayed from the oil spray nozzle 33, preventing waste caused by excessive lubricant spray and further improving the utilization rate of the lubricant. During operation, the sealing ring 22 in the sealing mechanism 2 fits tightly against the fixed shell 21 and the connecting block 23, enhancing the sealing effect and preventing lubricant leakage and external impurities from entering the bearing body 1, thereby further improving the service life of the bearing. The arrangement of the fixed shell 21, connecting block 23, limiting block 24 and fixing block 25 enhances the connection stability between the bearing body 1 and the sealing mechanism 2, preventing the sealing ring 22 from aging and deforming during long-term high-speed operation, effectively preventing lubricant leakage and external impurities from entering, thereby slowing down the wear of the bearing raceway and improving the service life of the bearing.
