摘要
为了对八沟道等速万向节内套进行结构和静强度设计,从钢球选型出发,对八沟道等速万向节内套进行了结构参数正向设计。对内套危险截面进行了全场静强度设计,以理想静强度场为目标,定量匹配了危险截面静强度的材料、热处理,并对全场静强度设计进行了定量评价。使用MTS静扭转试验机对等速万向节总成进行了静强度扭转试验,并用显微硬度计对内套进行了显微硬度试验以验证理论,结果表明按照基于强度场的机械结构和零部件的静强度设计与匹配方法设计的八沟道等速万向节星形套能够满足强度和功能需求。
In order to design the structure and static strength of the eight-channel constant speed universal joint inner sleeve. In this paper,based on the steel ball selection,the top-down design of structural parameters for the eight channel constant speed universal joint inner sleeve is carried out. The whole field static strength design of internal dangerous section was carried out. We matched the materials and heat treatments of dangerous section with the ideal static strength field. The static strength design was evaluated quantitatively. We carried out the static strength torsion test of constant speed universal joint assembly by using MTS static torsion testing machine,and the inner sleeve was subjected to a micro hardness test to verify the theory. The results show that the eight-channel constant speed universal joint inner sleeve designed according to the static strength design method of structure based on strength field can meet the strength and functional requirements.
