Abstract
Abstract A coupling for two shafts subject to misalignment includes an adapter secured to one of the shafts. A sleeve member is nonrotatably secured to the adapter by a retaining ring and has inwardly extending gear teeth. An outer hub member is positioned in the bore of the sleeve member and has both outwardly and inwardly extending gear teeth. The outwardly extending gear teeth mate with the sleeve member inwardly extending gear teeth and nonrotatably connect the outer hub and sleeve member. The outer hub outwardly extending gear teeth have an arcuate configuration so that the hub member is deflectable angularly. The outer hub member has a shoulder portion that limits angular deflection. An inner hub member is secured to the other of the shafts and is positioned within the bore of the outer hub member. The inner hub member has outwardly extending gear teeth that mate with the inwardly extending gear teeth of the outer hub member to nonrotatably connect the inner and outer hub members. The inner hub member gear teeth have an arcuate configuration so that the inner hub member is deflectable angularly to a limited extent. The outer hub member has a thrust plate enclosing an end portion and a thrust bar within the shaft urges the inner hub member into axial alignment with the outer hub member. The shafts are disconnected by removing the retainer ring and sliding the sleeve member over a shaft away from the adapter. The sleeves of a pair of couplings are also connected to each other to connect a pair of misaligned shafts.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
166 words
A gear type coupling comprising, a sleeve member having inwardly extending gear teeth, an outer hub member positioned in said sleeve member and having an annular body portion with outwardly extending gear teeth and inwardly extending gear teeth, said outer hub member outwardly extending gear teeth positioned between said sleeve member inwardly extending gear teeth to provide a nonrotatable connection therebetween, said outer hub member operable to deflect angularly relative to said sleeve, an inner hub member having outwardly extending gear teeth positioned within said outer hub member with said outwardly extending gear teeth positioned between said outer hub member inwardly extending gear teeth to provide a nonrotatable connection therebetween, said inner hub member operable to deflect angularly relative to said sleeve and said outer hub member, and Resilient means urging said outer hub member axially against said inner hub member to maintain said outer hub member axially aligned with said inner hub member while said outer hub member deflects angularly relative to said sleeve member.
Claim 2
Dependent Claim
166 words
A gear type coupling comprising, a sleeve member having inwardly extending gear teeth, an outer hub member positioned in said sleeve member and having an annular body portion with outwardly extending gear teeth and inwardly extending gear teeth, said outer hub member outwardly extending gear teeth positioned between said sleeve member inwardly extending gear teeth to provide a nonrotatable connection therebetween, said outer hub member operable to deflect angularly relative to said sleeve, an inner hub member having outwardly extending gear teeth positioned within said outer hub member with said outwardly extending gear teeth positioned between said outer hub member inwardly extending gear teeth to provide a nonrotatable connection therebetween, said inner hub member operable to deflect angularly relative to said sleeve and said outer hub member, and Resilient means urging said outer hub member axially against said inner hub member to maintain said outer hub member axially aligned with said inner hub member while said outer hub member deflects angularly relative to said sleeve member.
Claim 3
Dependent Claim
56 words
A gear type coupling as set forth in claim 1 in which, said outer hub member outwardly extending gear teeth and said inner hub member outwardly extending gear teeth having an arcuate configuration to permit angular deflection of said hub members relative to each other and relative to said sleeve member and maintain nonrotatable connections therebetween.
Claim 4
Dependent Claim
50 words
A gear type coupling as set forth in claim 1 which includes, a radially outwardly extending annular shoulder portion on said outer hub member body portion operable to abut said sleeve member inwardly extending gear teeth to limit angular deflection of said outer hub member relative to said sleeve member.
Claim 5
Dependent Claim
31 words
A gear type coupling as set forth in claim 1 in which, said resilient means urges an inwardly extending annular shoulder on said outer hub member against said inner hub member.
Claim 6
Dependent Claim
90 words
A gear type coupling as set forth in claim 1 which includes, a spindle shaft nonrotatably secured to said inner hub member and having an axial bore therein, and a thrust rod positioned in said bore and abutting a thrust plate secured to said outer hub member, said resilient means urging said thrust rod against said thrust plate to thereby urge an inwardly extending annular shoulder portion on said outer hub member against said inner hub member to maintain said inner hub member axially aligned with said outer hub member.
Claim 7
Dependent Claim
87 words
A gear type coupling as set forth in claim 1 which includes, a spindle shaft secured to said inner hub member, an adapter member positioned in the bore of said sleeve in nonrotatable relation thereto, and retaining means to secure said adapter to said sleeve and prevent axial movement of said sleeve relative to said adapter member, said sleeve member operable upon removal of said retaining means to move axially on said shaft away from said adapter member to thereby disconnect said shaft from said adapter member.
Claim 8
Dependent Claim
97 words
A gear type coupling as set forth in claim 6 in which, said adapter member includes an annular shoulder portion having one annular surface abut said sleeve member inwardly extending gear teeth to thereby limit axial movement of said sleeve member relative to said adapter member in one direction, said retaining means including an annular retainer ring removably secured to the annular end portion of said sleeve member and abutting the other annular surface of said annular shoulder portion to thereby limit axial movement of said sleeve member relative to said adapter member in the opposite direction.
Claim 9
Dependent Claim
57 words
A gear type coupling as set forth in claim 1 in which, said sleeve member has a radially outwardly extending flange member operable to be secured to a similar flange member of a second gear type coupling to nonrotatably connect a pair of shafts that are angularly deflectable relative to each other by means of said coupling.
Claim 10
Dependent Claim
49 words
A gear type coupling as set forth in claim 8 in which, said resilient means includes a pair of coil springs urging said outer hub members away from each other into abutting relation with said inner hub members to thereby maintain said inner and outer hub members axially aligned.
Claim 11
Dependent Claim
91 words
A gear type coupling as set forth in claim 1 in which, a spindle shaft is connected to said inner hub member and extends axially therefrom, said inner hub member and a portion of said spindle shaft extending into the bore of said sleeve member, an annular plate secured to and extending inwardly from said sleeve member, and a second annular plate secured to said spindle shaft and having an annular portion in overlying abutting relation with a portion of said annular plate thereby sealing the bore on said sleeve member.
