本文分析了微型轴承浪形保持架,机械压爪装配方法,认为保持架兜孔变形和错位是影响轴承动性能的要害。采用激光焊接保持架后,不仅能消除上述缺陷,提高轴承动性能,而且焊接速度快,不需用带爪保持架,因此可提高保持架材料利用率,减少保持架加工时间及相应减少模具,为微型轴承自动化装配创造了条件。文中对激光焊接装置及焊接工艺作了专门介绍,并对激光焊接装配轴承与压爪装配轴承的动性能作了对比分析。附图6幅,表9个。
This article analyzes the miniature bearing wave cage, mechanical pressure claw assembly method that the cage pockets deformation and dislocation is the key to affect the dynamic performance of the shaft. The use of laser welding cage, not only to eliminate the above shortcomings and improve the dynamic performance of the bearings, and welding speed, do not need to use claw cage, which can improve cage material utilization, reduce cage processing time and the corresponding reduction of mold, Micro-bearings for the automated assembly to create the conditions. In this paper, laser welding device and welding process were specially introduced, and the dynamic performance of laser welding assembly bearing and compression claw assembly bearing were analyzed.
