Overall design method of multilayer rod end spherical hinge

The invention relates to the technical field of vibration reduction of elastic rubber parts, in particular to an overall design method of a multilayer rod end spherical hinge. The overall design method is characterized in that the overall performance of the spherical hinge is improved through the structural design of a rubber profile, a spacer bush and an outer sleeve, and specifically, the service life of the spherical hinge is prolonged through the design of the rubber profile, the service life of the spherical hinge is prolonged or the processing technology difficulty of the spherical hinge before vulcanization is reduced through the design of the spacer bush, and the processing technology difficulty of the spherical hinge before the vulcanization is reduced or the service life of the spherical hinge is prolonged through the design of the outer sleeve. 本发明涉及弹性橡胶件减震技术领域，具体涉及一种多层杆端球铰的整体设计方法，所述方法是分别通过对橡胶型面、隔套和外套的结构设计来提升球铰的整体性能，具体为通过对橡胶型面设计来提高球铰的使用寿命；通过对隔套的设计来提高球铰的使用寿命或降低球铰在硫化前的加工工艺难度；通过对外套的设计来降低球铰在硫化前的加工工艺难度或
