Description

Technical Field

[0001] The utility model relates to the technical field of bearing attachments, in particular to a bearing steel tube for a rolling bearing ring. Background Art

[0002] Bearing steel pipes are hot-rolled or cold-rolled, cold-drawn seamless steel tubes used to manufacture common rolling bearing rings. They have an outer diameter of 25-180 mm and a wall thickness of 3.5-20 mm. They are available in standard and high-precision grades. Bearing steel is used to manufacture balls, rollers, and bearing rings. In mechanical design and manufacturing, it's often necessary to mount bearings to the inner wall of a bearing steel pipe to ensure proper operation. Existing bearing steel pipes are mostly one-piece, creating a need for a bearing steel pipe with a convenient installation method.

[0003] For example, Chinese patent CN216519242U discloses a bearing steel tube for a rolling bearing ring, comprising an outer frame, multiple sets of springs evenly arranged inside the outer frame, an inner sleeve rod disposed on the outer side of the spring, an outer sleeve disposed at the bottom of the outer side of the inner sleeve rod, a clamping plate disposed at the bottom, hinged rods symmetrically hinged on both sides of the top of the clamping plate, and the hinged rods located inside the slide groove, which can effectively protect the bearing. However, the above-mentioned bearing steel tube uses springs to push the clamping plate to install and support the bearing ring, which may cause unstable clamping under vibration or impact loads, affecting the normal operation of the bearing. At the same time, the spring may lose its elasticity due to fatigue after long-term use, resulting in a weakened clamping force, affecting the stability and safety of the bearing ring.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0005] In view of the problems in the related art, the utility model proposes a bearing steel tube for a rolling bearing ring to overcome the above technical problems existing in the existing related art.

[0008] Furthermore, in order to realize the driving of the rolling bearing ring installation mechanism, the rolling bearing ring installation mechanism can be driven to install the bearing ring by rotating the driving connecting tube between two groups of symmetrically arranged steel sleeves. Limiting rings are provided at the top and bottom ends of the driving connecting ring. The cross section of the limiting ring is a T-shaped structure. The inner wall of the driving connecting ring is provided with an annular groove, and the inner bottom end of the annular groove is provided with a plurality of tooth grooves.

[0009] Furthermore, in order to achieve the coordinated installation between the steel sleeve and the connecting ring, a limiting groove cooperating with the limiting ring is opened on the outer wall of the steel sleeve close to the driving connecting ring.

[0010] Furthermore, in order to achieve the coordinated installation of the connecting column and the rolling bearing ring installation mechanism, a sliding groove is provided on the side of the connecting column, and an installation hole is provided on the inner wall of the sliding groove.

[0011] Furthermore, in order to achieve fixed installation of the bearing ring, the rolling bearing ring clamp is driven to move under the drive of the driving connecting ring, and then the bearing ring is supported and installed by multiple sets of rolling bearing ring clamps, which helps to prevent the bearing ring from loosening or shifting during operation, thereby improving the overall performance and life of the bearing. The rolling bearing ring installation mechanism includes a slider arranged inside the slide groove, a rolling bearing ring clamp is provided at one end of the slider, a rotating rod is embedded in the inner wall of the other end of the slider, and a gear matching the tooth groove is provided on one end of the rotating rod; the cross-section of the slider is a square structure, and the other end of the slider is provided with a threaded hole; the rotating rod is movably connected to the inner wall of the slide groove, and a thread matching the threaded hole is provided on the outer side of the end of the rotating rod away from the gear.
