Description

Technical Field

[0001] This utility model relates to the field of roller needle bearing technology, specifically a roller needle bearing with a flanged outer ring. Background Technology

[0002] In recent years, with the rapid development of industry, various sectors have placed higher demands on the performance and quality of bearings. As an indispensable key component in mechanical equipment, bearings are widely used in many fields such as automobiles, machine tools, construction machinery, aerospace, and agricultural machinery.

[0003] However, traditional roller needle roller bearings have limited load-bearing capacity. Many modern mechanical devices need to operate under complex conditions and withstand loads in multiple directions, while traditional bearings can only withstand loads in one direction. This cannot meet the needs of these devices. Furthermore, when equipment uses bearings that can only withstand loads in one direction under complex conditions, the bearings may not be able to effectively distribute and transfer the load, leading to excessive local stress and increased friction and wear. Therefore, we offer roller needle roller bearings with flanged outer rings. Utility Model Content

[0004] The purpose of this invention is to provide a roller needle bearing with an outer ring flange to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a roller needle bearing with an outer ring flange, comprising: a bearing body;

[0006] The bearing outer ring is located outside the bearing body;

[0007] A flange that is fixedly connected to the outer wall of the bearing outer ring;

[0008] The bearing inner ring is located inside the bearing body.

[0009] A rubber ring fixedly connected to the inner wall of the outer ring of the bearing;

[0010] And a mounting assembly fixedly connected between the outer ring and the inner ring of the bearing; the mounting assembly includes a lubrication mechanism rotatably connected between the outer ring and the inner ring of the bearing, and a connecting mechanism is provided on the side of the lubrication mechanism.

[0011] Preferably, the lubrication mechanism includes a cage rotatably connected to the inner surface of the bearing outer ring. The outer wall of the cage has a transverse mounting groove, and a transverse needle roller is rotatably connected to the inner surface of the transverse mounting groove. An oil outlet hole is formed on the inner surface of the transverse mounting groove. An auxiliary cage is provided on the side of the cage. A vertical mounting groove is formed on the side of the auxiliary cage near the cage. A vertical needle roller is rotatably connected to the inner surface of the vertical mounting groove. An oil outlet hole is formed on the outer side of the cage. An oil passage cavity is formed on the outer wall of the side end of the cage. The top of the oil passage cavity is connected to the bottom of the oil inlet hole. The oil inlet hole is connected to the top of the bearing outer ring and the rubber ring.

[0012] Preferably, the connecting mechanism includes a protective plate that is snapped between the outer ring and the inner ring of the bearing. The top of the protective plate has a limiting groove. The inner surface of the limiting groove is slidably connected to a positioning rod one and a positioning rod two. The top end of the positioning rod one penetrates the inner surface of the limiting groove and is snapped into the inner surface of the positioning groove one, which is located on the inner wall of the outer ring of the bearing. The bottom end of the positioning rod two penetrates the inner surface of the limiting groove and is snapped into the inner surface of the positioning groove two, which is located on the outer wall of the inner ring of the bearing. The bottom of the positioning rod one is fixedly connected to the top of the positioning rod two by a connecting spring.

[0013] Preferably, the number of auxiliary retainers is set to two, and the two auxiliary retainers are symmetrically arranged on both sides of the retainer. The surfaces of the auxiliary retainers are rotatably connected to the inner wall of the outer ring of the bearing and the outer wall of the inner ring of the bearing, respectively, to ensure the smooth operation of the bearing, ensure the normal rolling of the vertical needle rollers, and avoid the vertical needle rollers from being skewed or stuck.

[0014] Preferably, the outer wall of the vertical needle roller is arranged to contact the outer side of the cage, which can enhance the synergistic effect between the cage and the vertical needle roller, allowing them to cooperate better during rotation and helping to distribute the load more evenly on the needle roller and the cage.

[0015] Preferably, the inner side of the oil passage cavity is connected to oil outlet hole one and oil outlet hole two respectively, which can realize the effective delivery of lubricating oil, provide good lubrication, and reduce friction and wear.

[0016] Preferably, the inner side of the protective plate is arranged in contact with the outer side of the auxiliary retainer, and the protective plate can protect the internal structure and prevent foreign objects from entering the bearing.

[0017] Compared with the prior art, the present invention provides a roller needle bearing with a flanged outer ring, which has the following advantages:

[0018] This flanged roller needle bearing uses transverse needle rollers to evenly distribute the load, ensuring smooth operation and reducing the friction coefficient between the transverse needle rollers and the inner and outer rings. An auxiliary cage is mounted on the side of the cage, and vertical needle rollers further enhance the bearing's load-bearing capacity. The interaction between the vertical and transverse needle rollers allows the bearing to withstand loads in different directions, enabling it to adapt to more complex operating conditions. Lubricating oil enters the oil passage through the inlet hole and then reaches the working surfaces of the transverse and vertical needle rollers through outlet holes one and two. This further reduces the friction coefficient between the transverse needle rollers and the inner and outer rings, as well as between the vertical needle rollers and the cage. Simultaneously, the lubricating oil is evenly distributed throughout the entire structure, achieving comprehensive and effective lubrication.

[0019] This flanged roller needle bearing features a protective plate that prevents external dust and impurities from entering the bearing, while also preventing lubricant leakage and maintaining effective lubrication circulation. This ensures stable lubrication. Positioning rods one and two are respectively engaged in positioning groove one on the outer ring and positioning groove two on the inner ring, accurately determining their relative positions and guaranteeing precision during installation and use. The annular design of both positioning grooves ensures smooth and stable operation of the outer and inner rings. Attached Figure Description

[0031] The outer ring 2 of the bearing is located outside the bearing body 1;

[0036] Preferably, the lubrication mechanism 51 includes a retainer 511 rotatably connected to the inner surface of the bearing outer ring 2. The outer wall of the retainer 511 has a transverse mounting groove 512. A transverse needle roller 513 is rotatably connected to the inner surface of the transverse mounting groove 512. An oil outlet hole 518 is provided on the inner surface of the transverse mounting groove 512. An auxiliary retainer 514 is provided on the side of the retainer 511. A vertical mounting groove 515 is provided on the side of the auxiliary retainer 514 near the retainer 511. A vertical needle roller 516 is rotatably connected to the inner surface of the vertical mounting groove 515. An oil outlet hole 519 is provided on the outer side of the retainer 511. An oil passage cavity 517 is provided on the outer wall of the side end of the retainer 511. The top of the oil passage cavity 517 is connected to the bottom of the oil inlet hole 510. The oil inlet hole 510 is connected to the top of the bearing outer ring 2 and the rubber ring 6.

[0037] In this embodiment, the number of auxiliary retainers 514 is set to two. The two auxiliary retainers 514 are symmetrically arranged on both sides of the retainer 511. The surfaces of the auxiliary retainers 514 are rotatably connected to the inner wall of the bearing outer ring 2 and the outer wall of the bearing inner ring 4, respectively, to ensure the smooth operation of the bearing, ensure the normal rolling of the vertical needle rollers 516, and avoid the vertical needle rollers 516 from being skewed or stuck.

[0038] Furthermore, the outer wall of the vertical needle roller 516 is arranged to contact the outer side of the cage 511, which can enhance the synergistic effect between the cage 511 and the vertical needle roller 516, so that the two can cooperate better during rotation and help to distribute the load more evenly.

[0039] Furthermore, the inner side of the oil passage cavity 517 is connected to the first oil outlet 518 and the second oil outlet 519 respectively, which can realize the effective delivery of lubricating oil, provide good lubrication, and reduce friction and wear.

[0040] Example 2: Based on Example 1, the roller needle roller bearing with an outer ring flange provided by this utility model, such as... Figures 1 to 7 As shown: The connecting mechanism 52 includes a protective plate 521 that is snapped between the outer ring 2 and the inner ring 4 of the bearing. The top of the protective plate 521 is provided with a limiting groove 522. The inner surface of the limiting groove 522 is slidably connected to a positioning rod 1 523 and a positioning rod 2 526. The top end of the positioning rod 1 523 passes through the inner surface of the limiting groove 522 and is snapped into the inner surface of the positioning groove 1 524. The positioning groove 1 524 is located on the inner wall of the outer ring 2 of the bearing. The bottom end of the positioning rod 2 526 passes through the inner surface of the limiting groove 522 and is snapped into the inner surface of the positioning groove 2 527. The positioning groove 2 527 is located on the outer wall of the inner ring 4 of the bearing. The bottom of the positioning rod 1 523 is fixedly connected to the top of the positioning rod 2 526 by a connecting spring 525.

[0041] In this embodiment, the inner side of the protective plate 521 is in contact with the outer side of the auxiliary retainer 514. The protective plate 521 can protect the internal structure and prevent foreign objects from entering the bearing.

[0042] Furthermore, both positioning groove 1 524 and positioning groove 2 527 are set as annular grooves, so that the outer ring 2 and the inner ring 4 of the bearing can operate smoothly and stably.

[0043] In actual operation, when this device is in use, the transverse needle rollers 513 rotate within the mounting groove 512. The cage 511 prevents the transverse needle rollers 513 from rubbing and colliding with each other, allowing the transverse needle rollers 513 to bear the load evenly and ensuring the smooth operation of the bearing. An auxiliary cage 514 is provided on the side of the cage 511, and the vertical needle rollers 516 increase the bearing's load-bearing capacity. Through the cooperation of the vertical needle rollers 516 and the transverse needle rollers 513, the bearing can bear loads in different directions, enabling it to adapt to more complex working conditions, while also providing lubrication. Oil can enter the oil passage cavity 517 through the oil inlet hole 510, and then reach the working surfaces of the transverse needle roller 513 and the vertical needle roller 516 through the first oil outlet hole 518 and the second oil outlet hole 519. This reduces the coefficient of friction between the transverse needle roller 513 and the inner ring 4 and the outer ring 2 of the bearing, as well as the coefficient of friction between the vertical needle roller 513 and the cage 511. At the same time, it allows the lubricating oil to be evenly distributed throughout the structure, achieving comprehensive and effective lubrication. Meanwhile, the rubber ring 6 fits against the top of the oil passage cavity 517, sealing the oil passage cavity 517 and preventing leakage.

[0044] The protective plate 521, secured between the inner ring 4 and outer ring 2 of the bearing, prevents external dust and impurities from entering the bearing. It also prevents lubricating oil leakage, maintaining effective circulation and ensuring stable lubrication. Positioning rods 523 and 526, respectively, are engaged in positioning grooves 524 and 527 of the outer ring 2 and inner ring 4, accurately determining their relative positions and ensuring precision during installation and use. The annular design of both positioning grooves 524 and 527 ensures smooth and stable operation of the outer and inner rings.
