Claims
- 1. In a gear type coupling comprising a floating shaft, hub means fixed to said floating shaft at each end thereof, said hub means having a plurality of outwardly extending gear teeth formed thereon, and sleeve means having an inner axial bore operably connected to a driving shaft and a driven shaft, said inner axial bore of said sleeve means having a plurality of inwardly extending gear teeth, said hub means and sleeve means rotatable by means of said gear teeth, the improvement comprising:
- intermediate sleeve means comprised of a driven member and a driving member fixed to the outwardly extending gear teeth of the hub means, said intermediate sleeve means having outwardly extending gear teeth which mesh and coact with said inwardly extending gear teeth of said axial bore of said sleeve means, said intermediate sleeve means having a contoured shear connection of reduced cross-sectional area operably connecting and providing radial clearance between the surfaces of the driven and driving members of the intermediate sleeve means and said shear connection being substantially axially aligned with said gear teeth formed on said hub means and said sleeve means.
- 2. The gear coupling of claim 1 wherein said intermediate sleeve means includes bearing means adapted to engage the surface of the driven and driving members of said intermediate sleeve means.
- 3. In a gear type coupling comprising a floating shaft, hub means fixed to said floating shaft at each end thereof, said hub means having a plurality of outwardly extending gear teeth formed thereon, and sleeve means having an inner axial bore operably connected to a driven shaft and driving shaft, said inner axial bore of said sleeve means having a plurality of inwardly extending gear teeth, said hub means and sleeve means rotatable by means of said gear teeth, the improvement comprising: intermediate sleeve means comprised of a driven member and driving member fixed to said inwardly extending gear teeth of said axial bore of said sleeve means said intermediate sleeve means having inwardly extending gear teeth which mesh and coact with said outwardly extending gear teeth formed on said hub means, said intermediate sleeve means having a contoured shear connection of reduced cross-sectional area operably connecting and providing radial clearance between the surfaces of the driven and driving members of the intermediate sleeve means and said shear connection being substantially axially aligned with said gear teeth formed on said hub means and said sleeve means.
- 4. The gear coupling of claim 3 wherein said intermediate sleeve means includes bearing means adapted to engage the surface of the driven and driving members of said intermediate sleeve means.
