摘要： A washer for a male or female threaded fastener includes an annular ring portion and a seat portion with a cantilever portion extending therebetween. The washer hardness is selected to exceed the threaded fastener hardness by an amount that enhances the elastic deflection of the washer and reduces the tendency of the fastener to loosen. The selected hardness relationship also reduces the washer diameter dilation during loading and the permanent deformation of the washer diameter.

摘要： A cantilevered washer for a male or female threaded fastener having a conical seat portion including an conically-shaped seat for receiving the threaded fastener in such maner as to load the washer at an angle and relieve hoop-stress on the threaded fastener. The washer further has an annular ring portion including a flat annular base for mating with a surface of a part being fastened. The annular ring portion and the conical seat portion are connected by a cantilever portion which is inclined at an angle of substantially 45.degree. to the flat bearing portion in order to provide a low profile vertical displacement between the conical seat portion and the flat bearing portion, as well as provide a location for deflection of variable bearing loads. Since deflection occurs only at the cantilever portion and since the conically-shaped seat loads the washer at an angle, brinelling into the surface of a part being fastened is essentially eliminated and loosening of a threaded fastener during operation is prevented. The washer is preferred to be fabricated using cold forming tenchniques in order to ensure proper metal grip structure so that deflection at the cantilever portion is predictable and free of metal fatigue. The washer is further preferred to be connected with an associated threaded fastener in a manner that permits free relative rotation therebetween.
摘要翻译： 一种用于阳螺纹或阴螺纹紧固件的悬臂垫圈，其具有锥形座部分，其包括锥形座，用于以这种方式接收螺纹紧固件，以一定角度加载垫圈并减轻螺纹紧固件上的环向应力。 垫圈还具有环形环部分，该环形部分包括用于与被紧固的部件的表面配合的平坦的环形基座。 环形环部分和圆锥形座部分通过悬臂部分连接，该悬臂部分与平坦轴承部分以大致45度的角度倾斜，以便在圆锥形座部分与平坦轴承部分之间提供低的垂直位移， 以及提供可变轴承负载偏移的位置。 由于偏转仅在悬臂部分发生，并且由于圆锥形座椅以一定角度装载垫圈，所以基本上消除了进入被紧固的部件的表面的镶嵌，并且防止了在操作期间螺纹紧固件的松动。 为了确保合适的金属把手结构，使得悬臂部分的挠曲是可以预测的并且没有金属疲劳，优选使用冷成型工艺来制造垫圈。 垫圈进一步优选地以相互联接的螺纹紧固件连接，以允许它们之间的自由相对旋转。
