[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a load-bearing bearing comprises an inner sleeve 2, balls 3 and an outer sleeve 1, the inner sleeve 2 is provided with a groove for positioning the balls 3, the outer sleeve 1 is provided with an annular groove 4 for rolling the balls 3, the annular groove 4 is provided with an opening groove 8 for moving the balls 3 into or out of the annular groove 4, the groove is spirally arranged along the axial direction of the inner sleeve 2, and the rise angle of the spiral is the same as the angle between the opening groove 8 and the annular groove 4, a plurality of dividing strips 5 for separating the balls 3 at different positions in the axial direction are arranged in the axial direction of the outer sleeve 1, the dividing strips 5 are annularly arranged along the circumference of the outer sleeve 1, and a plurality of dividing strips 5 are provided with mounting grooves 9 which are maintained on the same spiral line as the opening groove 8.

[0019] This product separates adjacent balls 3 by grooves and utilizes the spiral distribution of the grooves so that two adjacent balls 3 are separated in different annular grooves 4 by the dividing strips 5 during operation. This reduces the rolling frequency of the balls 3 in a single annular groove 4 when the bearing is running at high speed, thereby reducing wear and heat accumulation, and reducing bearing damage caused by thermal expansion due to heat accumulation. The design of the mounting groove 9 enables the spirally distributed balls 3 to be directly delivered into the outer sleeve 1 according to the angle of the spiral when the outer sleeve 1 and the inner sleeve 2 are being installed, thereby achieving a quick installation effect.

[0020] A locking groove is provided on the inner sleeve 2, and a disassembly groove is provided on the outer sleeve 1. A locking ball rolls in the locking groove. When the locking groove and the disassembly groove cooperate, a channel is formed for the locking ball to pass through. When the locking groove cooperates with the disassembly groove, the ball 3 is misaligned with the mounting groove 9. The setting of the locking groove can prevent the ball 3 on the inner sleeve 2 from moving along the mounting groove 9 due to axial force during rotation after the installation of the product is completed, thereby preventing the outer sleeve 1 and the inner sleeve 2 from separating. After the locking groove and the disassembly groove are aligned, the ball 3 is misaligned with the mounting groove 9. When subjected to axial force, the dividing strip 5 can provide support for the ball 3, thereby keeping the ball 3 in the annular groove 4 to prevent the ball 3 from running off the track during high-speed rotation and causing the inner and outer sleeves 1 to separate.

[0021] The inner sleeve 2 is provided with a detachable closing cover 6, which can separate the locking groove from the outside world. The setting of the closure cover 6 can fix the locking bead in place to prevent the locking bead from escaping from the locking groove when the bearing is in use, thereby making the product more stable when in use. The outer sleeve 1 is provided with a detachable insert block 7, which can close the disassembly groove, further locate the position of the locking bead, and further prevent the locking bead from escaping.

[0022] The outer sleeve 1 is provided with a lubrication cover at the opening groove 8, and the lubrication cover is provided with a hole for adding lubricating oil. The bearing is separated from the outside world by the lubrication cover to prevent dust from entering. At the same time, the lubrication hole can be used to directly inject lubricating oil, which has the effect of quickly adding lubricating oil. At the same time, the lubrication cover can be made of transparent material, and the lubrication condition inside the bearing can be directly viewed by using the transparent material.

[0023] When this product is in use, the balls 3 are dispersed along the axis, so that the bearing can provide better support for the shaft. When a bending force occurs on the shaft, two balls 3 that are not in the same axial section can use two-point one-line support to avoid bending of the shaft, thereby supporting the shaft through the lever effect.

[0024] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0025] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
