Abstract
Abstract Male and female splined members are axially retained by an external split retaining ring at the accessible side of the female member and an internal split retaining ring occupying confronting grooves in the male and female members. The male and female members are disassembled by removing the external split retaining ring, over-inserting the male member to permit self expansion of the internal split retaining ring into a capturing release groove of the female member, and withdrawing the male member.

Claim 1
Independent Claim
229 words
A splined assembly with retaining rings comprising, a male part having a splined portion, a first retaining groove, and a second retaining groove spaced axially therefrom, a female member having a splined bore mating with the splined portion of the male member and a side face surrounding the splined bore at one end, said splined bore having a retention groove spaced axially from said side face and a release groove located on the side of the retention groove remote from said side face, a removable split retaining ring disposed in the first retaining groove of the male member and engaging the side face of the female member for limiting insertion of the male member into the female member and aligning the second retaining groove of the male member with the retention groove of the female member, a second split retaining ring disposed in the second retaining groove of the male member and the retention groove of the female member under radial compression for preventing withdrawal of the male member from the female member, said male member being further insertable into the female member upon removal of the split retaining ring to a disassembly position where the second split retaining ring aligns with the release groove and self expands out of the second retaining groove into the release groove to permit withdrawal of the male member from the female member.

A splined assembly with retaining rings comprising, a male part having a splined portion, a first retaining groove, and a second retaining groove spaced axially therefrom, a female member having a splined bore mating with the splined portion of the male member and a side face surrounding the splined bore at one end, said splined bore having a retention groove spaced axially from said side face and a release groove located on the side of the retention groove remote from said side face, a removable split retaining ring disposed in the first retaining groove of the male member and engaging the side face of the female member for limiting insertion of the male member into the female member and aligning the second retaining groove of the male member with the retention groove of the female member, a second split retaining ring disposed in the second retaining groove of the male member and the retention groove of the female member under radial compression for preventing withdrawal of the male member from the female member, said male member being further insertable into the female member upon removal of the split retaining ring to a disassembly position where the second split retaining ring aligns with the release groove and self expands out of the second retaining groove into the release groove to permit withdrawal of the male member from the female member.
Claim 3
Dependent Claim
300 words
A splined assembly with retaining rings comprising, a male member having a splined portion, a first retaining groove and a second retaining groove spaced axially therefrom, said second retaining groove having parallel side walls which are perpendicular to the axis of the male member, a female member having a splined bore mating with the splined portion of the male member and a side face surrounding the splined bore at one end, said splined bore having a retention groove spaced axially from said side face and a juxtaposed release groove located at the side of the retention groove remote from said side face, said retention groove having a side wall at the side toward said side face which is perpendicular to the axis of the splined bore and said release groove having a side wall at the side remote from said side face which is perpendicular to the axis of the splined bore, a removable split retaining ring disposed in the first retaining groove of the male member and engaging the side face of the female member for axially retaining the male and female members in the assembly direction and aligning the second retaining groove of the male member with the retention groove of the female member, a second split retaining ring disposed in the second retaining groove of the male member and the retention groove of the female member under radial compression for axially retaining the male and female members in the disassembly direction, said male member being further insertable into the female member upon removal of the split retaining ring to a disassembly position where the second split retaining ring self expands out of the second retaining groove of the member and is captured by the release groove to permit withdrawal of the male member from the female member.
