Abstract
The present invention relates to a drive assembly including an adapter that enables the use of a lightweight backstopping clutch with a driven shaft. The adapter is coupled to the driven shaft for rotation therewith and forms a stub shaft smaller than the driven shaft. The clutch has an inner race that is disposed about the stub shaft and an outer race fixed against rotation so as to allow rotation of the stub shaft and driven shaft in one direction and inhibit rotation in an opposition direction.
Claims20
A drive assembly, comprising:
- a driven shaft;
- an adapter coupled to said driven shaft for rotation therewith;
- said adapter forming a stub shaft smaller than said driven shaft;
- and
- a backstopping clutch having an inner race disposed about said stub shaft and an outer race fixed against rotation, said clutch allowing rotation of said stub shaft and driven shaft in a first direction and inhibiting rotation in a second direction opposite said first direction.
A drive assembly, comprising:
- a driven shaft;
- an adapter having a first side and a second side, wherein a closed bore is defined on said first side of said adapter and a stub shaft extends from said second side of said adapter, said closed bore receiving said driven shaft for rotation therewith;
- a split ring having at least one arcuate portion disposed about said driven shaft and coupled to said adapter;
- and
- a backstopping clutch, wherein said clutch includes an inner race disposed about said stub shaft and an outer race, said clutch allowing rotation of said stub shaft and driven shaft in a first direction and inhibiting rotation in a second direction opposite said first direction.
The drive assembly of claim 15 wherein said stub shaft of said adapter is smaller than said driven shaft.
A method of assembling a drive assembly, comprising the steps of:
- providing a driven shaft, an adapter defining a closed bore on a first side and a stub shaft on a second side, a split ring having a plurality of arcuate portions, and a backstopping clutch;
- inserting said driven shaft through said split ring;
- removing a spacer between first and second arcuate portions of said split ring;
- inserting a fastener through said first and second arcuate portions;
- inserting an end of said driven shaft into said closed bore of said adapter;
- securing said split ring to said adapter using a fastener;
- placing an inner race of said clutch over said stub shaft;
- and
- fixing an outer race of said clutch against rotation.
