Method of securing first and second splined members together
View Patent ↗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.
1. A method of securing first and second splined members together comprising the steps of:
(a) providing a first splined member including an outer surface having a recess and a plurality of external splines provided thereon;
(b) providing a second splined member including an inner surface having a plurality of internal splines provided thereon;
(c) disposing the inner surface of the second splined member about the outer surface of the first splined member such that the plurality of internal splines cooperate with the plurality of external splines; and
(d) deforming a portion of the splines of the second splined member into the recess of the first splined member to secure the first and second splined members together.
2. The method defined in claim 1 wherein said step (a) is performed by providing an annular recess that extends completely about the circumference of the first splined member.
3. The method defined in claim 1 wherein said step (a) is performed by providing a recess that is generally trapezoidal in cross sectional shape, including a pair of angled, linear side walls and a linear bottom wall.
4. The method defined in claim 1 wherein said step (a) is performed by providing a recess that is located adjacent to the plurality of external splines.
5. The method defined in claim 1 wherein said step (d) is performed by staking.
6. The method defined in claim 5 wherein said step (d) is performed by providing a staking tool and moving the staking tool into engagement with a portion of the first splined member.
7. The method defined in claim 5 wherein said step (d) is performed by providing a rolling staking tool and moving the rolling staking tool into engagement with a portion of the first splined member while the assembly of the first and second splined members is rotated relative thereto.
8. The method defined in claim 5 wherein said step (d) is performed by providing a pair of staking tools and moving the pair of staking tools into engagement with opposed portions of the first splined member.
9. The method defined in claim 5 wherein said step (d) is performed by providing a pair of staking tools and moving the pair of staking tools simultaneously into engagement with opposed portions of the first splined member.
10. The method defined in claim 1 wherein said step (a) is performed by providing a midship tube shaft of a driveshaft assembly as the first splined member and wherein said step (b) is performed by providing an end yoke of a driveshaft assembly as the second splined member.
11. A method of securing a midship tube shaft to an end fitting comprising the steps of:
(a) providing a midship tube shaft including an outer surface having a recess and a plurality of external splines provided thereon;
(b) providing an end fitting including an inner surface having a plurality of internal splines provided thereon;
(c) disposing the inner surface of the end fitting about the outer surface of the midship tube shaft such that the plurality of internal splines cooperate with the plurality of external splines; and
(d) deforming a portion of the splines of the end fitting into the recess of the midship tube shaft to secure the midship tube shaft to the end fitting.
12. The method defined in claim 11 wherein said step (a) is performed by providing an annular recess that extends completely about the circumference of the midship tube shaft.
13. The method defined in claim 11 wherein said step (a) is performed by providing a recess that is generally trapezoidal in cross sectional shape, including a pair of angled, linear side walls and a linear bottom wall.
14. The method defined in claim 11 wherein said step (a) is performed by providing a recess that is located adjacent to the plurality of external splines.
15. The method defined in claim 11 wherein said step (d) is performed by staking.
16. The method defined in claim 15 wherein said step (d) is performed by providing a staking tool and moving the staking tool into engagement with a portion of the midship tube shaft.
17. The method defined in claim 15 wherein said step (d) is performed by providing a rolling staking tool and moving the rolling staking tool into engagement with a portion of the midship tube shaft while the assembly of the midship tube shaft and the end yoke is rotated relative thereto.
18. The method defined in claim 15 wherein said step (d) is performed by providing a pair of staking tools and moving the pair of staking tools into engagement with opposed portions of the midship tube shaft.
19. The method defined in claim 15 wherein said step (d) is performed by providing a pair of staking tools and moving the pair of staking tools simultaneously into engagement with opposed portions of the midship tube shaft.
