浇口对高速精密圆柱滚子轴承注塑保持架质量的影响

摘要

以高速精密圆柱滚子轴承注塑保持架为研究对象，应用 Moldflow 分析软件对浇口位置和数量进行模拟分析，设计合理的浇口方案；并通过装机试验和性能检测优化保持架结构和保持架模具浇口的位置和数量，增加了注塑保持架强度和承载能力，有效解决了注塑保持架断裂的问题。%Taking injection plastic cages in high speed precision Roller bearings as research object,the position and quantity of sprue are simulated and analyzed by using analysis software Moldflow.The reasonable sprue scheme is de-signed,and the position and quantity of sprue for mold and structure of cages are optimized through assembly test and performance detection.The strength and load carrying capacity of injection plastic cages are improved,and the problem is effectively solved about fracture of injection plastic cages.
