China 03-0181-07 Gearless Turntable Bearing Produced by Luoyang Dz Factory., Find details about China Four-Point Contact Ball Turntable Bearing., Ball Bearing from 03-0181-07 Gearless Turntable Bearing Produced by Luoyang Dz Factory.
1. Small bearing design thickness. 03-0181-07 type bearings are designed to avoid wear caused by direct contact between rolling elements and rings at the beginning of structure design. The raceway adopts heat treatment to strengthen the hardness, stiffness and toughness of materials. The overall thickness of bearings is small, and the bearing occupies a small machine volume. However, the thickness cannot be reduced indefinitely, because it is affected by the surface roughness of bearings and journals, the stiffness of shaft friction, and the geometric errors between shafts and journals. Second, the bearing inner ring rotates with small installation interference and negative clearance. Under normal circumstances, the inner ring of the bearing will rotate with the shaft as a rotating part. In order to prevent the relative sliding between the bearing and the inner ring and the defects such as wear or creep, there should be a small surplus between the inner ring of the bearing and the shaft, or the bearing should adopt negative clearance to ensure the rotation accuracy of the cross roller bearing. III. Mechanical load and impact load of 03-0181-07 single row cylindrical roller bearing. When the bearing runs on the main engine, it will inevitably bear mechanical load and impact load. However, this load value is limited, that is, the rated load of the bearing. Therefore, when selecting bearings, the load of equipment should be considered comprehensively. Cross-roller turntable bearings occupy a small space and have a relatively high load bearing relative to the load of this section, and then the bearings that can bear these loads should be selected.
