Abstract
Description
Technical Field
[0001] The present application relates to the technical field of industrial machinery parts, and specifically to a roller bearing for a forklift mast. Background Art
[0002] With the vigorous development of the logistics industry, forklifts, as important handling tools, the stability and durability of their mast systems have become particularly critical. Forklift mast roller bearings, as key components, bear huge loads and friction.
[0003] However, existing bearings have no additional support parts, resulting in insufficient bearing capacity, which can cause them to deform, break, and fail under heavy load conditions, thereby affecting the stability and safety of the forklift. Long-term heavy-load operations will also accelerate bearing wear and shorten its service life. Utility Model Content
[0004] In response to the shortcomings of the existing technology, the present application provides a roller bearing for a forklift mast, which has advantages such as high load-bearing capacity. It solves the problem that the existing bearings have no additional support parts, resulting in insufficient load-bearing capacity of the bearings, which will cause them to deform, break and other failures under heavy load conditions, thereby affecting the stability and safety of the forklift. Long-term heavy-load operations will also accelerate the wear of the bearings and shorten their service life.
[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a roller bearing for a forklift mast, comprising an inner ring, an outer ring and a retaining frame, wherein a plurality of rollers arranged in a ring array are rotatably connected inside the retaining frame, a slide plate is fixedly connected on both sides of the inner and outer walls of the retaining frame, a plurality of rotating shafts arranged in a ring array are fixedly connected on both sides of the retaining frame, and support wheels are rotatably connected to the outsides of the plurality of rotating shafts, a first slide groove, a first slide groove and a second slide groove are provided on both sides of the outer wall of the inner ring, and a second slide groove and a third slide groove are provided on both sides of the inner wall of the outer ring.
[0006] Through the above solution, a stable support structure is formed between the inner ring and the outer ring by arranging a retaining frame between the inner ring and the outer ring, and rotatably connecting multiple rollers in a ring array inside the retaining frame, and arranging first baffles on both sides of the inner wall of the outer ring. At the same time, the multiple rotating shafts and support wheels in a ring array arranged on both sides of the retaining frame further enhance the supporting capacity and stability of the bearing, so that the bearing can withstand a larger load, thereby improving the stability and safety of the forklift.
[0007] Furthermore, first baffles are fixedly connected to both sides of the inner wall of the outer ring.
[0008] Through the above solution, the setting of the first baffle effectively limits the axial movement of the inner ring and the outer ring, thereby enhancing the axial stability of the bearing and preventing the bearing from axially moving under heavy load or complex working conditions. In addition to limiting axial movement, the first baffle also provides additional support for the bearing, further enhancing the overall load-bearing capacity and stability, which helps to extend the service life of the bearing and reduce the failure rate.
[0009] Furthermore, the outer walls of the plurality of rotating shafts are fixedly connected to two second baffles that are arranged in a mirror-image distribution, and the supporting wheel is rotatably arranged between the two second baffles.
[0010] Through the above scheme, the setting of the second baffle effectively limits the axial movement of the support wheel, thereby enhancing the stability of the support wheel, preventing the support wheel from falling off or axially moving during operation, and improving the reliability and safety of the bearing. By rotating the support wheel between the two second baffles, it helps to distribute the load more evenly and reduce the wear and deformation of the bearing.
[0011] Furthermore, an inner lining is fixedly connected to the inner wall of the inner ring.
[0012] Through the above solution, the liner can reduce friction and wear between the inner ring and the shaft, thereby extending the overall service life of the bearing.
[0013] Furthermore, the retaining frame is rotatably arranged between the inner ring and the outer ring.
[0014] Through the above scheme, the main function of the cage is to evenly distribute the rollers between the inner ring and the outer ring, ensuring a uniform gap between them, thereby avoiding direct contact and collision between the rolling elements, reducing friction and wear. The cage also plays a role in guiding the movement of the rolling elements. During the operation of the bearing, the cage can ensure that the rolling elements roll smoothly along the predetermined track, thereby improving the operating efficiency and stability of the bearing. The design of the cage can also optimize the lubrication effect of the bearing. By ensuring a uniform gap between the rolling elements, the cage helps to evenly distribute the grease or lubricating oil, thereby reducing friction and heat generation, and extending the service life of the bearing.
[0015] Furthermore, the slide plate is slidably arranged between the first slide groove and the third slide groove.
[0016] Through the above scheme, the skateboard can slide between the first slide groove and the third slide groove. As part of the supporting structure, the skateboard can enhance the stability of the entire system. By sliding in the slide groove, the skateboard can disperse the load and reduce single-point force, thereby improving the load-bearing capacity and durability of the entire system.
[0017] Furthermore, the plurality of support wheels are rotatably arranged between the first slideway and the second slideway.
[0018] Through the above solution, the rotation setting of multiple support wheels between the first slide and the second slide provides stable support for the forklift mast, can effectively disperse the load, reduce single-point force, thereby improving the stability and carrying capacity of the entire system. The rotation of the support wheels in the slide and the design of the slide provide a clear guide path for the support wheels, making the movement of the mast smoother and more accurate.
[0019] Furthermore, the two first baffles are both slidably arranged inside the second sliding groove.
[0020] Through the above solution, the two first baffles can slide inside the second slide groove, which can provide additional support to enhance the stability of the structure, and the bearing is sealed by the first baffle, thereby preventing the influence of dust on the outer wall on the inside of the bearing.
[0021] Compared with the existing technology, the technical solution of this application has the following beneficial effects:
[0022] This roller bearing for a forklift mast forms a stable support structure between the inner and outer rings by arranging a retaining frame between the inner and outer rings, rotatably connecting multiple rollers in a ring array inside the retaining frame, and arranging first baffles on both sides of the inner wall of the outer ring. At the same time, the multiple rotating shafts and support wheels in a ring array arranged on both sides of the retaining frame further enhance the supporting capacity and stability of the bearing, allowing the bearing to withstand greater loads and improving the stability and safety of the forklift.

[0031] See also Figure 2 、 Figure 3 and Figure 4 , both sides of the inner wall of the outer ring 2 are fixedly connected with a first baffle 13. The setting of the first baffle 13 effectively limits the axial movement of the inner ring 1 and the outer ring 2, thereby enhancing the axial stability of the bearing and preventing the bearing from axially moving under heavy load or complex working conditions. In addition to limiting axial movement, the first baffle 13 also provides additional support for the bearing, further enhancing the overall load-bearing capacity and stability, which helps to extend the service life of the bearing and reduce the failure rate. The outer walls of multiple rotating shafts 6 are fixedly connected to two second baffles 14 arranged in a mirror-image distribution, and the support wheel 7 is rotatably set between the two second baffles 14. The setting of the second baffle 14 effectively limits the axial movement of the support wheel 7, thereby enhancing the stability of the support wheel 7, preventing the support wheel 7 from falling off or axially moving during operation, and improving the reliability and safety of the bearing. By rotatably setting the support wheel 7 between the two second baffles 14, it helps to distribute the load more evenly and reduce the wear and deformation of the bearing.
[0032] See also Figure 1 、 Figure 2 and Figure 4, the inner wall of the inner ring 1 is fixedly connected with an inner lining 15, which can reduce the friction and wear between the inner ring 1 and the shaft, thereby extending the overall service life of the bearing, and the retaining frame 3 is rotatably arranged between the inner ring 1 and the outer ring 2. The main function of the retaining frame 3 is to evenly distribute the rollers 4 between the inner ring 1 and the outer ring 2, ensuring that the gap between them is uniform, thereby avoiding direct contact and collision between the rolling elements, reducing friction and wear, and the retaining frame 3 also plays a role in guiding the movement of the rolling elements. During the operation of the bearing, the retaining frame 3 can ensure that the rolling elements roll smoothly along the predetermined track, thereby improving the operating efficiency and stability of the bearing.

By ensuring that the gap between the rolling elements is uniform, the retaining frame 3 helps to evenly distribute the grease or lubricating oil, thereby reducing friction and heat generation, and extending the service life of the bearing. The slide plate 5 is slidingly arranged between the first slide groove 8 and the third slide groove 12. The slide plate 5 can slide between the first slide groove 8 and the third slide groove 12 The slide plate 5 slides between the first and second slides 9 and 11, and the slide plate 5, as part of the supporting structure, can enhance the stability of the entire system. By sliding in the slide groove, the slide plate 5 can disperse the load and reduce the single-point force, thereby improving the load-bearing capacity and durability of the entire system. Multiple support wheels 7 are rotatably arranged between the first slide 9 and the second slide 11. The rotation setting of multiple support wheels 7 between the first slide 9 and the second slide 11 provides a stable support for the forklift door frame, which can effectively disperse the load and reduce the single-point force, thereby improving the stability and load-bearing capacity of the entire system. The rotation of the support wheel 7 in the slide, the design of the slide provides a clear guide path for the support wheel 7, making the movement of the door frame smoother and more accurate. The two first baffles 13 are both slidably arranged inside the second slide groove 10. The two first baffles 13 can slide inside the second slide groove 10, which can provide additional support to enhance the stability of the structure, and the bearing is closed by the first baffle 13, thereby preventing the influence of dust on the outer wall on the inside of the bearing.
[0033] In this embodiment, a roller bearing for a forklift mast forms a stable support structure between the inner ring 1 and the outer ring 2 by arranging a retaining frame 3 between the inner ring 1 and the outer ring 2, and rotatably connecting multiple rollers 4 in a ring array inside the retaining frame 3, and arranging first baffles 13 on both sides of the inner wall of the outer ring 2. At the same time, multiple rotating shafts 6 and support wheels 7 in a ring array arranged on both sides of the retaining frame 3 further enhance the supporting capacity and stability of the bearing, so that the bearing can withstand a larger load, thereby improving the stability and safety of the forklift.
[0034] It should be noted that the lining 15 is made of brass, which has excellent corrosion resistance and high strength, so that the brass lining 15 can effectively resist corrosion and wear, thereby improving the durability and reliability of the bearing.
[0035] The working principle of the above embodiment is:
[0036] The roller bearing is composed of components such as the inner ring 1, the outer ring 2 and the cage 3. During installation, the inner ring 1 is tightly matched with the shaft of the forklift mast, while the outer ring 2 is fixedly connected to the corresponding components on the mast. The cage 3 is precisely placed between the inner ring 1 and the outer ring 2. The roller 4 and the support wheel 7 inside it are positioned and fixed by the structure on the cage 3 and the rotating shaft 6 respectively. The lining 15 is made of brass and fits tightly on the inner wall of the inner ring 1 to reduce friction and wear between the shaft. When the forklift mast is lifted or moved, the roller 4 rolls along the tracks of the inner ring 1 and the outer ring 2 inside the cage 3 to provide necessary support and guidance. At the same time, the support wheel 7 rolls between the first slide 9 and the second slide 11. They The fixation of the rotating shaft 6 and the second baffle 14 ensures stable bearing capacity. The slide plate 5, as part of the retaining frame 3, slides between the first slide groove 8 and the third slide groove 12. This design not only enhances the overall stability of the bearing, but also disperses the load and reduces single-point force. The two first baffles 13 slide inside the second slide groove 10. They not only provide additional support and enhance the stability of the structure, but also seal the bearing by sliding, effectively blocking the influence of dust on the outer wall on the inside of the bearing. During the operation of the forklift, the bearing needs to bear the weight from the door frame and cargo. Through the rolling of the roller 4 and the support wheel 7 and the support of the slide plate 5 and the first baffle 13, the bearing can effectively disperse and carry these loads.
