Description

Technical Field

[0001] The utility model relates to the field of ball bearings, in particular to a novel ball bearing. Background Art

[0002] Ball bearings, as a type of rolling bearing, significantly reduce friction and improve mechanical transmission efficiency by rolling spherical alloy steel balls between inner and outer rings. They are compact, lightweight, and have high precision, high speed, low friction, and a certain load capacity. They are widely used in machine tools, automobiles, aerospace, and other fields. The standardized production of ball bearings ensures easy replacement and maintenance, while the diverse types meet the needs of different application scenarios.

[0003] The inventors of this application have found the following problems in practical use:

[0004] In the current manual assembly process of ball bearings, some designs such as the attached Figure 1 It is shown that a notch 5 is cleverly opened on the relative edges of the inner ring and the outer ring. This design is intended to facilitate the precise placement of the ball at the notch during assembly, and then the ball is smoothly embedded into the slide by knocking, thereby greatly improving the convenience of assembly and reducing the resistance when the ball is engaged into the slide. However, this design also has its limitations: the existence of the notch inevitably weakens the restraint ability of this position on the ball, resulting in a decrease in the stability of the ball after assembly and the overall structural strength, which has become a problem that urgently needs to be optimized.

[0005] Therefore, it is necessary to provide a novel ball bearing to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical problem to be solved by the present invention is that the existence of the notch undoubtedly reduces the limiting effect of the notch position on the ball. In view of the above-mentioned defects of the prior art, a new ball bearing is provided.

[0007] To achieve the above-mentioned purpose, the technical solution of the present invention is: a new ball bearing, comprising an inner ring and an outer ring, an adaptive mechanism is provided on one side of the outer ring, the adaptive mechanism includes a cavity, and a movable block is slidingly provided inside the cavity, a groove is formed on one side of the cavity, a pressure spring is installed between the movable block and the inner wall of the cavity, a fastening bolt is provided at the central axis of the pressure spring, the fastening bolt is threadedly connected to the outer ring, and the end head abuts against the movable block.

[0008] By adopting the above technical solution, by turning the fastening bolt, it can be gradually penetrated along the threaded connection path with the outer ring until the end face of the fastening bolt is tightly abutted against the movable block. This abutment operation not only provides a stable supporting force for the movable block, but also firmly locks the movable block in a preset position through physical contact, effectively preventing it from accidental movement during the operation of the bearing.

[0009] It is further provided that a slide groove is provided on one side of the inner wall of the cavity, and a slider is provided on one side of the movable block and at a position opposite to the slide groove. The slider is slidably connected to the slide groove to limit the position of the movable block.

[0010] By adopting the above technical solution, not only is it ensured that the movable block can move smoothly along the predetermined trajectory when subjected to external force, but the position of the movable block is also effectively limited through the close cooperation between the slide groove and the slider to prevent it from deviating or shaking.

[0011] It is further provided that the fastening bolts and the assembly holes of the outer ring can be selectively installed using an embedded structure.

[0012] By adopting the above technical solution, the embedded structure can not only fix the fastening bolts more firmly on the outer ring, but also effectively reduce the exposed part of the bolts, thereby reducing the risk of damage caused by external force collision or friction.

[0013] It is further provided that the groove is in an arc-shaped structure, which serves as the maximum movable boundary of the movable block.

[0014] By adopting the above technical solution, it is ensured that the movable block does not exceed the predetermined range during the movement process, thereby avoiding bearing damage or performance degradation due to excessive movement.

[0015] It is further provided that a slideway is provided on the outer side of the inner ring and the inner side of the outer ring, and a plurality of balls are slidably provided on the inner side of the slideway.

[0016] By adopting the above technical solution, the balls can roll freely in the slideway, thereby achieving low friction and high-efficiency transmission of the bearing. At the same time, the uniform distribution of multiple balls also ensures that the bearing can maintain stable performance when bearing load, avoiding bearing damage caused by local overload.

[0017] It is further provided that the movable block and the inner side surface of the outer ring are in the same curved surface structure, and a limiting groove is formed on one side of the movable block to perform preliminary limiting on the ball.

[0018] By adopting the above technical solution, the movable block can fit tightly on the inner side of the outer ring, thereby enhancing the overall structural strength of the bearing. At the same time, the same curved surface structure also ensures that the movable block can maintain a stable posture during movement, providing good limiting properties for the inner ball, and avoiding the degradation of bearing performance due to posture changes.

[0019] It is further provided that the movable block is adapted to the cavity, and the static position of the movable block does not conflict with the slideway.

[0020] By adopting the above technical solution, it is ensured that the movable block can move freely in the cavity without getting stuck or shaking, which not only improves the sensitivity and stability of the bearing, but also reduces the risk of bearing damage caused by poor fit between the movable block and the cavity.

[0021] Compared with the related art, the new ball bearing provided by the present invention has the following beneficial effects:

[0022] The utility model provides a novel ball bearing. By turning the fastening bolt and utilizing the threaded connection between the fastening bolt and the outer ring, the protruding length of the fastening bolt can be accurately adjusted. When the fastening bolt is gradually tightened, the end thereof will abut against the movable block, applying a stable pressure to the movable block. This pressure not only ensures that the position of the movable block in the cavity is fixed, but also transmits the pressure to the ball through the movable block, thereby enhancing the limiting property of the ball, so that the bearing can maintain more stable performance when subjected to heavy loads or running at high speeds.

[0023] The utility model provides a new type of ball bearing, which adopts a slider and a slide groove. The sliding connection between the slide groove and the slider provides additional position limitation for the movable block. When the movable block is subjected to the abutment force of the fastening bolt, the slider will fit tightly in the slide groove to prevent the movable block from deflecting or shaking. This double limitation mechanism effectively fills the traditional notch structure with the movable block, eliminating the adverse effect of the notch on the ball limiting performance.

[0030] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings, in which typical embodiments of the present invention are shown. Example

[0031] like Figure 1-5 As shown, the new ball bearing of the present invention includes an inner ring 1 and an outer ring 2. An adaptive mechanism 6 is provided on one side of the outer ring 2. The adaptive mechanism 6 includes a cavity 601, and a movable block 602 is slidably provided inside the cavity 601. A groove 603 is formed on one side of the cavity 601. A pressure spring 605 is installed between the movable block 602 and the inner wall of the cavity 601. A fastening bolt 606 is provided at the central axis of the pressure spring 605. The fastening bolt 606 is threadedly connected to the outer ring 2, and the end thereof abuts against the movable block 602. By twisting the fastening bolt 606, it can be made to follow the threaded connection path with the outer ring 2. Gradually go deeper until the end face of the fastening bolt is tightly abutted against the movable block 602. This abutting operation not only provides a stable supporting force for the movable block, but also firmly locks the movable block in a preset position through physical contact, effectively preventing it from accidentally moving during the operation of the bearing. At the same time, the sliding matching mechanism of the slide groove 607 and the slider 608 provides an additional position limitation for the movable block 602. When the movable block 602 is subjected to the abutment force of the fastening bolt 606, the slider 608 will be fine-tuned along the trajectory of the slide groove 607 to ensure that the movable block 602 can be accurately aligned with and fill the traditional notch 5 structure. Example

[0032] like Figure 4 As shown, a slide groove 607 is provided on one side of the inner wall of the cavity 601, and a slider 608 is provided on one side of the movable block 602 and at a position opposite to the slide groove 607. The slider 608 is slidably connected to the slide groove 607 to limit the position of the movable block 602, which not only ensures that the movable block 602 can move smoothly along a predetermined trajectory when subjected to external force, but also effectively limits the position of the movable block 602 through the close cooperation between the slide groove 607 and the slider 608 to prevent it from deviating or shaking. At the same time, the design of the sliding connection also reduces the friction resistance of the movable block 602 when it moves, so that the movable block 602 can respond to external force more easily, improves the sensitivity and stability of the bearing, and further, is conducive to limiting the position of the movable block 602 when it is static.

[0033] like Figure 4 、 Figure 5 As shown, the assembly holes of the fastening bolts 606 and the outer ring 2 can be optionally installed using an embedded structure. The embedded structure not only enables the fastening bolts 606 to be more firmly fixed to the outer ring 2, but also effectively reduces the exposed part of the bolts, reducing the risk of damage caused by external force collision or friction. At the same time, this installation method also makes the appearance of the bearing more neat and beautiful, and improves the overall quality of the product. In addition, the fastening bolts 606 with an embedded structure are also easy to maintain and replace, reducing maintenance costs and time costs.

[0034] like Figure 3 、 Figure 4 、 Figure 5 As shown, the groove 603 is an arc-shaped structure, which is the maximum boundary of the movable block 602, ensuring that the movable block 602 will not exceed the predetermined range during the movement, thereby avoiding bearing damage or performance degradation due to excessive movement. At the same time, the arc-shaped groove 603 conforms to the moving trajectory of the movable block 602, so that the movable block 602 can move more smoothly and without obstruction, and the arc shape matches the outer surface of the ball 4, which is convenient for limiting the ball 4.

[0035] like Figure 4 As shown, slideways 3 are provided on the outer side of the inner ring 1 and the inner side of the outer ring 2, and a number of balls 4 are slidingly arranged on the inner side of the slideway 3, so that the balls 4 can roll freely in the slideway 3, thereby realizing low friction and high-efficiency transmission of the bearing. At the same time, the uniform distribution of multiple balls 4 also ensures that the bearing can maintain stable performance when bearing loads, avoiding bearing damage caused by local overload. In addition, the sliding arrangement of the slideway 3 and the balls 4 also enables the bearing to adapt to various complex forms of movement, such as rotation, tilting, etc., thereby improving the versatility and adaptability of the bearing.

[0036] like Figure 4 、 Figure 5 As shown, the movable block 602 and the inner side surface of the outer ring 2 are in the same curved surface structure, and a limiting groove 604 is formed on one side of the movable block 602 to perform preliminary positioning of the ball 4, so that the movable block 602 can fit tightly on the inner side surface of the outer ring 2, thereby enhancing the overall structural strength of the bearing. At the same time, the same curved surface structure also ensures that the movable block 602 can maintain a stable posture during movement, provides good positioning for the inner ball 4, and avoids the degradation of bearing performance due to posture changes. In addition, the limiting groove 604 design on one side of the movable block performs a preliminary positioning effect on the ball 4, so that the ball 4 can be more accurately positioned in the slideway during the assembly process, thereby improving the assembly accuracy and stability of the bearing.

[0037] like Figure 4 、 Figure 5As shown, the movable block 602 is adapted to the cavity 601, and the static position of the movable block 602 does not conflict with the slide 3, ensuring that the movable block 602 can move freely in the cavity 601 without getting stuck or shaking, which not only improves the sensitivity and stability of the bearing, but also reduces the risk of bearing damage caused by poor fit between the movable block 602 and the cavity 601. At the same time, the design that the static position of the movable block 602 does not conflict with the slide 3 is also crucial, ensuring that when the bearing is in a stationary state, the movable block 602 will not interfere with the rolling and positioning of the ball 4 in the slide 3, thereby ensuring the initial performance and stability of the bearing.

[0038] During implementation, first, the ball 4 is placed on the inner side of the limiting groove 604 to provide a certain limiting effect for the ball 4. Then, a certain pressing force and knocking force are applied to the ball 4. As the ball 4 is pressed, the movable block 602 overcomes the elasticity of the pressure spring 605 and moves inside the cavity 601, providing a larger embedding space for the ball 4, thereby reducing the assembly resistance of the ball 4 until the ball 4 is forced to be clamped on the inner side of the slide 3, completing the installation operation of the ball 4. Then, multiple balls 4 are assembled one by one, and then the fastening bolt 606 can be screwed, and the fastening bolt 606 is connected to the outer ring 2 by thread, so that the fastening bolt 606 is abutted against the movable block 602, and cooperates with the slide groove 607 and the slider 608 to limit the position of the movable block 602, which is conducive to filling the traditional notch 5 structure with the movable block 602, enhancing the limiting property of the ball 4 there, and improving its assembly structure strength.

[0039] The advantages of this technical solution in practical applications include but are not limited to the following:

[0040] 1. As the fastening bolt is gradually tightened, its end firmly abuts against the movable block 602, exerting a stable and reliable thrust on the movable block to ensure that the movable block can accurately fill the traditional notch 5 structure. This filling process eliminates the adverse effect of the notch on the limiting property of the ball 4;

[0041] 2. The sliding fit between the sliding groove 607 and the slider 608 provides additional position constraints for the movable block 602.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
