Abstract
A method for retaining lubrication in a splined joint comprises the steps of forming a seal between an inward surface of a grease seal cup and a first component, forming another seal between an outward surface of the grease seal cup and a sealing member extending from a second component, and engaging an end portion of the grease seal cup with an end portion of the first component, so that the end portion of the grease seal cup resists axial displacement of the grease seal cup during engagement of the first component with the second component. The grease seal cup of the method has a cylindrical portion integral with the end portion. The cylindrical portion has a tapered annular wall with the inward and outward surfaces. The end portion of the grease seal cup extends radially and inwardly from the cylindrical portion, so that the tapered annular wall is squeezed between the first component and the sealing member. The pre-fabricated light weight grease seal cup can be used in existing splined joints without adversely affecting the weight balance.
