Abstract
Description
Technical Field
[0001] The utility model relates to the field of machinery, and particularly relates to a bearing seat assembly. Background Art
[0002] In modern industrial machinery and equipment, bearings, as key components for supporting rotating parts, reducing friction and transmitting loads, their performance and reliability directly affect the operating efficiency and lifespan of the entire system. Previously, in a crane wheel set, a bearing chamber was required. A bearing was installed in the bearing chamber. After being installed on the wheel shaft, a front end cover and a rear bearing chamber retaining cover were needed for the bearing chamber. This has always been the traditional installation method. Although this installation method has been continuously used, the process is complex. For each additional processing step, there is an additional risk associated with that processing step, and thus it needs to be improved. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a bearing seat assembly that is convenient to install and has a reliable structure for the above problems.
[0004] To achieve the above purpose, the utility model discloses a bearing seat assembly, including an inner ring. Its structural feature is that: an outer ring is sleeved on the inner ring, a plurality of rollers are installed between the outer ring and the inner ring, the outer ring extends outward along its radial direction, and a positioning hole for fixing the bearing is provided on the side of the outer ring.
[0005] In the improved bearing, the bearing chamber on the equipment can be cancelled, and the original outer ring of the bearing is thickened, which not only serves as the outer ring of the bearing but also plays the role of the bearing chamber. Moreover, a positioning hole is provided on the outer ring, and the retaining cover hole on the original bearing chamber is transferred to the outer ring of the bearing. With such improvement, the installation and processing steps are reduced, the assembly process is reduced, the processing cost and the assembly cost are reduced, and at the same time, the rejection rate and the material cost are greatly reduced.
[0006] An inwardly recessed card slot is provided on the outer peripheral part of the outer ring. The card slot is used for installation and fixation, and also provides convenience for subsequent maintenance and repair.
[0007] There are two rows of rollers, and the two rows of rollers are arranged at intervals along the inner ring. The double-row rollers can further improve the bearing capacity and stability of the bearing. The interval arrangement helps to reduce the mutual interference between the rollers and improve the rotation accuracy.
[0008] The two rows of rollers are arranged staggeredly. The staggeredly arranged rollers can more effectively disperse the load, reduce the stress concentration phenomenon, and improve the fatigue life of the bearing. At the same time, this layout also helps to improve the rotation smoothness of the bearing.
[0009] A cage for supporting the rollers is sleeved on the inner ring. The cage provides a stable support platform for the rollers, prevents the rollers from shifting or falling off during rotation, and is convenient for maintaining the geometric accuracy and rotation performance of the bearing.
[0010] The left and right sides of the cage are provided with retaining grooves, and the inner ends of the rollers are inserted into the retaining grooves. The retaining grooves ensure the correct positioning and fixation of the rollers in the cage, prevent the rollers from wobbling and vibrating during high-speed rotation, and also help improve the rotational accuracy and stability of the bearing.
[0011] On the left and right sides of the inner ring, there are retaining edges for blocking the rollers, and the outer ends of the rollers are abutted against the retaining edges. The retaining edges can prevent the rollers from axially moving, ensuring the stable position of the rollers inside the bearing. This helps reduce the vibration and noise caused by the axial movement of the rollers and improves the reliability and service life of the bearing.
[0012] The rollers are cylindrical rollers, which have good rolling characteristics and load-bearing capacity, and can maintain stable rotational performance under high-speed and heavy-load conditions. At the same time, their simple geometric shape is also convenient for machining and manufacturing.
[0013] On the inner wall of the outer ring, there are inwardly recessed positioning grooves, and the upper parts of the rollers are located in the positioning grooves. The positioning grooves provide additional positioning and support for the rollers, helping to reduce the wobbling and offset of the rollers during rotation and further improving the rotational accuracy and stability of the bearing.
[0014] In summary, the beneficial effects of the present utility model are as follows: The improved bearing can cancel the bearing housing on the equipment, thicken the original outer ring of the bearing, which not only serves as the outer ring of the bearing but also plays the role of the bearing housing, and a positioning hole is provided on the outer ring, and the cover hole on the original bearing housing is transferred to the outer ring of the bearing. With such improvement, the installation and processing procedures are reduced, the assembly process is reduced, the processing cost and assembly cost are reduced, and at the same time, the rejection rate and material cost are greatly reduced.
