Description

Technical Field

[0001] This utility model belongs to the field of slewing bearing technology, specifically relating to a positioning slewing bearing with an installation auxiliary structure. Background Technology

[0002] The working principle of slewing bearings is based on rolling friction. When the inner or outer ring is subjected to an external force, the rolling elements roll within the raceway, allowing the inner and outer rings to rotate relative to each other while bearing the corresponding load. The rolling of the rolling elements effectively reduces frictional resistance, improves transmission efficiency, and reduces energy loss. In the field of mechanical equipment manufacturing, slewing bearings are key components for achieving relative rotational motion, and their installation accuracy directly affects the stability and reliability of equipment operation.

[0003] Traditional slewing bearing installation typically relies on manual positioning, depending on the installer's experience and judgment for alignment. This method is not only inefficient but also struggles to guarantee high installation accuracy, easily leading to errors that can even affect the equipment's lifespan. Even when auxiliary positioning structures are introduced in some installation processes, existing structures are often complex in design and cumbersome in adjustment, requiring repeated adjustments and calibrations during installation, increasing installation time and labor costs. Therefore, there is an urgent need to design a slewing bearing installation structure that can improve installation efficiency and accuracy while simplifying the operation process. Utility Model Content

[0004] The purpose of this invention is to provide a positioning slewing bearing with an installation auxiliary structure. This addresses the problem that traditional slewing bearing installation typically relies on manual positioning, depending on the installer's experience and judgment. This method is not only inefficient but also struggles to guarantee high installation accuracy, easily leading to installation errors that can even affect the equipment's lifespan. Even when auxiliary positioning structures are introduced into some installation processes, existing structures are often complex in design and cumbersome in adjustment, requiring repeated adjustments and calibrations during installation, increasing installation time and labor costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning slewing bearing with an installation auxiliary structure, comprising an inner ring, an outer ring sleeved on the outer wall of the inner ring, and two symmetrical notches formed on the surface of the outer ring; Each of the recesses is equipped with an alignment plate, and a side post is welded to each of the two sides of the alignment plate near the inside of the recess. The other end of the side post is in contact with the inner wall of the recess. The alignment plate forms a rotating structure with the inside of the recess through the side posts on both sides.

[0006] In order to enable the alignment plate to be adjusted in height and lateral orientation inside the recess, as a positioning slewing bearing with an installation auxiliary structure of this utility model, preferably, an L-shaped groove is opened on each of the inner walls of the two sides of the recess, and the internal dimensions of the L-shaped groove are adapted to the diameter of the side column. The side post has an inner cavity near the end that contacts the notch. A spring is connected to the inner wall of the inner cavity. The other end of the spring abuts against the outer wall of the ball. One side of the outer wall of the ball abuts against the inner wall of the L-shaped groove. A semi-circular opening that matches the ball is provided on the inner wall of the lateral end of the L-shaped groove.

[0007] In order to fix the alignment plate at the end of the notch in the lateral direction, as a positioning slewing bearing with an installation auxiliary structure of this utility model, preferably, the inner diameter of the opening end of the inner cavity is smaller than the diameter of the ball, three-quarters of the ball is disposed in the inner cavity, the two outer walls of the alignment plate are in contact with the inner wall of the notch, and when the alignment plate is at the bottom of the L-shaped groove, its surface is located at the bottom of the opening end of the notch.

[0008] Compared with the prior art, the beneficial effects of this utility model are: When positioning and installing a slewing bearing, two symmetrical openings opposite the recess are pre-made on the surface of the mating end. The alignment plate is then adjusted upwards along the L-shaped groove and then laterally. This allows the alignment plate to extend from the recess. When the slewing bearing is then mated with the mating end, the alignment plate aligns with the corresponding opening on the mating end. Once aligned, the slewing bearing is precisely connected to the mating end, facilitating subsequent fixing. This structure significantly improves the installation efficiency of the slewing bearing and saves on labor costs. Attached Figure Description

[0014] 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.

[0015] Please see Figure 1-4 The present invention provides the following technical solution: a positioning slewing bearing with an installation auxiliary structure, including an inner ring 1, an outer ring 2 sleeved on the outer wall of the inner ring 1, and a rolling component between the inner ring 1 and the outer ring 2, so that the inner ring 1 and the outer ring 2 constitute a slewing bearing, and two recesses 3 are symmetrically opened on the surface of the outer ring 2. Each recess 3 has an movably arranged alignment plate 4 inside. A side post 5 is welded to each side of the alignment plate 4 near the inside of the recess 3. The other end of the side post 5 is in movable contact with the inner wall of the recess 3. The alignment plate 4 forms a rotating structure with the inside of the recess 3 through the side posts 5 on both sides.

[0016] Preferably, an L-shaped groove 31 is provided on each of the inner walls of the two sides of the notch 3, and the internal dimensions of the L-shaped groove 31 are adapted to the diameter of the side column 5. The side post 5 has an inner cavity 51 near the end that contacts the recess 3. A spring 52 is connected to the inner wall of the inner cavity 51. The other end of the spring 52 abuts against the outer wall of the ball 53. One side of the outer wall of the ball 53 abuts against the inner wall of the L-shaped groove 31. A semi-circular opening that matches the ball 53 is provided on the inner wall of the lateral end of the L-shaped groove 31.

[0017] In actual use, when the alignment plate 4 moves to the end of the horizontal part of the L-shaped groove 31, the spring 52 will drive the ball 53 to reset. After the ball 53 is reset, it will be squeezed into the semi-circular opening, so that the alignment plate 4 will be fixed in the adjusted position. When in use, align the alignment plate 4 with the pre-set opening on the docking end, so that the slewing bearing can be accurately connected to the docking end. Preferably, the inner diameter of the opening end of the inner cavity 51 is smaller than the diameter of the bead 53, three-quarters of the bead 53 is disposed in the inner cavity 51, the outer walls on both sides of the alignment plate 4 are in contact with the inner wall of the recess 3, and when the alignment plate 4 is at the bottom of the L-shaped groove 31, its surface is located at the bottom of the opening end of the recess 3.

[0018] In practical application, installation accuracy and efficiency are crucial during the positioning and installation of the slewing bearing. The specific operation involves first symmetrically machining two openings corresponding to the recess 3 on the mating end surface. These openings lay the foundation for subsequent installation. Next, the alignment plate 4 is adjusted along the trajectory of the L-shaped groove 31. This adjustment process is carried out in two steps: the first step is upward adjustment, allowing the alignment plate 4 to gradually move vertically, freeing it from its initial constrained position; the second step is lateral adjustment, through lateral sliding, allowing the alignment plate 4 to extend along the trajectory of the L-shaped groove 31 until it protrudes from the recess 3.

[0019] At this point, the slewing bearing is aligned with the mating end, and the extended alignment plate 4 is precisely aligned with the corresponding pre-drilled opening on the mating end. Once the alignment plate 4 is fully aligned with the opening on the mating end, the slewing bearing can be connected to the mating end with extremely high precision. Through the above structure, the installation efficiency of the slewing bearing can be significantly improved in actual use.

[0020] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
