磁电机轴承保持架的改进

Improvement on cage of magneto-generator bearing

磁电机轴承的保持架一般采用铜板冲压型,此类型保持架工艺复杂,需要多套冲压模具和工装等,致使轴承成本高,装配效率低。针对该问题,采用了一种工艺简单、成本低廉又能满足用户使用要求的增强尼龙PA66-GF25注塑成型保持架,替代了铜板冲压型保持架,降低了成本,提高了生产效率和轴承的性能。

Magneto-generator bearings were generally fitted with a pressed sheet-copper cage.The fabrication technology of such cage is complicated,which needed several sets of mould and tooling,resulting bearings in high cost and inefficiency with assembly.To counter the problem mentioned above,the PA66-GF25 enforced nylon injection molding cage with simple technology and low cost and meeting user＇s using reguirements was used instead of it.The productivity and properties of bearings were both improved while the cost decreased.
