Powered roller systems and methods

1. A powered roller system comprising:

a roller drum assembly comprising a drum member, a drum shaft, a drum bearing assembly, and a distal end plate;

a motor comprising a support shaft and a drive shaft, where the drum bearing assembly is arranged to support the drum member on the support shaft;

an adapter assembly comprising

an adapter collar and

an adapter spacer defining a set of spacer collar bores and a plurality of spacer plate bores;

a proximal support assembly for supporting the support shaft; and

a distal support assembly for supporting the drum shaft; wherein

the adapter collar is connected to the drive shaft and to the roller drum assembly through the adapter spacer;

the adapter spacer is detachably attached to the adapter collar using the set of spacer collar bores; and

the adapter spacer is selectively detachably attached to the first distal end plate and to the second distal end plate using the set of spacer plate bores.

2. A powered roller system as recited in claim 1 , further comprising a first set of bolts and a second set of bolts, in which:

the adapter collar defines a set of flange bolt openings;

the distal end plate defines a set of plate bolt openings;

the first set of bolts extend through the flange bolt openings and into the spacer collar bores; and

the second set of bolts extend through the spacer plate bores and into the second set of plate bolt openings.

3. A powered roller system as recited in claim 1 , in which the proximal support assembly comprises:

a support block defining center bore, first and second fluid bores, and first and second O-ring grooves;

first and second O-rings arranged within the first and second O-ring grooves, respectively; wherein

the first and second fluid bores extend between first and second fluid ports and first and second locations of the center bore;

the center bore is sized and dimensioned such that the O-rings engage the support shaft to define a sealed area, where the first and second locations are within the sealed area.

4. A powered roller system as recited in claim 3 , in which the first and second fluid bores define first and second fluid bore axes, where the first and second fluid bore axes are parallel to each other and the first and second fluid bore axes are different.

5. A powered roller system as recited in claim 3 , in which the first and second fluid bores define first and second fluid bore axes, where the first and second fluid bore axes are parallel to each other and aligned.

6. A powered roller system as recited in claim 3 , in which the first and second locations are arranged on opposite sides of the center bore.

7. A method of rotating a drum member relative to first and second structural members comprising the steps of:

providing a motor comprising a support shaft and a drive shaft;

arranging a first drum bearing assembly to support a first drum member on the support shaft;

providing an adapter assembly comprising an adapter collar and an adapter spacer, where the adapter spacer defines a set of spacer collar bores and a plurality of spacer plate bores;

connecting the adapter collar to the drive shaft and to the first drum member through the adapter spacer;

arranging a proximal support assembly to support the support shaft;

arranging a distal support assembly to support the drum shaft;

detachably attaching the adapter spacer to the adapter collar using the set of spacer collar bores; and

selectively detachably attaching the adapter spacer to the first distal end plate and to the second distal end plate using the set of spacer plate bores.

8. A method as recited in claim 7 , further comprising the steps of:

providing a first set of bolts and a second set of bolts;

the step of providing the adapter collar comprises the step of forming a set of flange bolt openings in the adapter collar;

the step of providing the distal end plate comprises the step of forming a set of plate bolt openings in the distal end plate;

extending the first set of bolts through the flange bolt openings and into the spacer collar bores; and

extending the second set of bolts through the spacer plate bores and into the second set of plate bolt openings.

9. A method as recited in claim 7 , in which the step of providing the proximal support assembly comprises the steps of:

providing a support block defining center bore, first and second fluid bores, and first and second O-ring grooves;

arranging first and second O-rings within the first and second O-ring grooves, respectively; wherein

forming the first and second fluid bores such that the first and second fluid bores extend between first and second fluid ports and first and second locations of the center bore;

sizing and dimensioning the center bore such that the O-rings engage the support shaft to define a sealed area, where the first and second locations are within the sealed area.

10. A method as recited in claim 9 , in which the first and second fluid bores define first and second fluid bore axes, where the first and second fluid bore axes are parallel to each other and the first and second fluid bore axes are different.

11. A method as recited in claim 9 , in which the first and second fluid bores define first and second fluid bore axes, where the first and second fluid bore axes are parallel to each other and aligned.

12. A method as recited in claim 9 , in which the first and second locations are arranged on opposite sides of the center bore.
