  • Method of securing first and second splined members together
    Patent number: 7726000
    Abstract: A method is provided for securing first and second splined members together, such as a midship tube shaft to an end fitting in a driveshaft assembly, to prevent relative axial movement from occurring therebetween. Initially, a first splined member is provided that includes an outer surface having a recess and a plurality of external splines provided thereon. Also, a second splined member is provided that includes an inner surface a plurality of internal splines provided thereon. The inner surface of the second splined member is disposed about the outer surface of the first splined member such that the plurality of internal splines cooperate with the plurality of external splines. Then, a portion of the second splined member is deformed into the recess of the first splined member to secure the first and second splined members together, while preventing relative axial movement from occurring therebetween.
