Wheel isolator coupling
View Patent ↗A wheel isolator coupling comprising a sprocket for engaging a drive member, the sprocket fixedly connected to a first adaptor, the sprocket rotationally engaged with a shaft through a first bearing, a wheel portion fixedly connected to a second adaptor, the wheel portion rotationally engaged with the shaft through a second bearing, the first adaptor having at least one receiving portion, at least one compressible member disposed within the receiving portion, the second adaptor having a radially extending member for engaging the compressible member within the receiving portion, and the sprocket imparting no axial force to the first bearing.
1. A wheel isolator coupling comprising:
a sprocket for engaging a drive member, the sprocket fixedly connected to a first adaptor;
the sprocket rotationally engaged with a shaft through a first bearing;
a wheel portion fixedly connected to a second adaptor;
the wheel portion rotationally engaged with the shaft through a second bearing;
the first adaptor having at least one receiving portion;
at least one compressible member disposed within the receiving portion;
the second adaptor having a radially extending member for engaging the compressible member within the receiving portion; and
the sprocket imparting no axial force to the first bearing.
2. The wheel isolator coupling as in claim 1 further comprising:
a cap connected to the second adaptor;
the cap disposed on an opposite side of the first adaptor from the second adapter.
3. The wheel isolator coupling as in claim 1 , wherein the drive member has a toothed surface.
4. The wheel isolator coupling as in claim 1 further comprising a plurality of compressible members.
5. The wheel isolator coupling as in claim 1 , wherein the first adaptor further comprises a member for interlocking the first adaptor with the second adaptor.
