该轴承是为天津夏利轿车发动机水泵设计的轴承。该轴承是一个组合单元,轴承和轴、密封圈、润滑脂连为一体,既减少了了轴承的重量,又缩少了体积。内部结构采用优化设计,外圈与双列密封球轴承相同,内圈为一长轴,轴径上有两个沟道,与一般轴承内圈完全不同。为保证其内外圈沟心距的加工精度,磨加工采用了进口的高精度磨床进行加工,轴的沟道与外径采用一次同时加工,保证了相互位置精度。采用专用注脂机严格控制注脂量,并有专用压盖机 The bearings are designed for the Tianjin Xiali sedan engine pump bearings. The bearing is a combination of units, bearings and shafts, seals, grease even as one, both to reduce the weight of the bearing, but also reduce the volume. The internal structure of the optimal design, the outer ring and double row sealed ball bearings the same, the inner ring is a long axis, the shaft diameter of the two channels, and the general bearing inner ring is completely different. In order to ensure the processing accuracy of the inner and outer ring ditch center of gravity, the grinding process adopts imported high-precision grinding machine for processing, and the channel and outer diameter of the shaft are processed at the same time to ensure the mutual position accuracy. The use of special lipid injection device strictly control the amount of fat, and a special capping machine
