摘要： The roller cone is retained to the head with axial play taken out of the bearings with a tension rod tensioned from the rear of the head and away from the nose bearing region of the head allowing greater resistance to loading in the region of the nose bearing and a reduction in critical stresses. The tension rod has a flat oriented for tightening and facing grease passages to allow grease to gain access to the bearings through the bore for the tension rod and otherwise fill the bore so the tension rod actively supports loading in the head bearing. The nose bearing is separately directly cone supported with a retainer threaded to the cone or a spacer between bearings can be used so that tensioning of the rod takes out the axial play in both bearings with force transmitted to a retainer at the back of the cone.
摘要翻译：滚子锥体被保持到头部，轴向从轴承中取出，张力杆从头部的后部拉伸并远离头部的鼻部支承区域，允许在鼻部轴承区域具有更大的阻力加载，减少临界应力。张力杆具有一个取向用于紧固和面对油脂通道的平面，以允许油脂通过用于张力杆的孔进入轴承，否则填充孔，使得拉杆主动地支撑在头部轴承中的负载。鼻部轴承分别直接锥形支撑，带有螺纹连接到锥体的保持器，或者可以使用轴承之间的间隔件，使得杆的张紧在两个轴承中轴向游动，其力传递到锥体后部的保持器。
