The conveyor assembly includes a conveyor module, a power module, and a chassis supporting the conveyor module and the power module. The conveyor module includes a roller rotatable about an axis and a conveyor belt shiftable in response to rotation of the roller. The power module provides rotational power to the roller. The power module includes a power assembly and a drive configured to transmit rotational power to the roller from the power assembly. The power assembly includes a power source and a housing at least substantially surrounding the power source. The chassis integrally forms a portion of the housing. ## Claims ### Claim 1 A conveyor system including a conveyor assembly, said conveyor assembly comprising: a conveyor module; a power module; and a chassis supporting the conveyor module and the power module, said conveyor module including a roller rotatable about an axis and a conveyor belt shiftable in response to rotation of the roller, said power module providing rotational power to the roller, said power module including a power assembly and a drive configured to transmit rotational power to the roller from the power assembly, said power assembly including a power source and a housing at least substantially surrounding the power source, said chassis integrally forming a portion of the housing, said housing including a shell at least substantially circumscribing the power source, said shell being directly mounted to the chassis, said chassis defining a circumferential mounting lip, said lip being received within and abutting said shell. ### Claim 2 (depends on 1) The conveyor system of claim 1, said power source including an output shaft rotatable about an axis, said power assembly further including a bearing assembly rotatably supporting the output shaft, said housing including a bearing support structure supporting the bearing assembly, said chassis integrally forming the bearing support structure. ### Claim 3 (depends on 2) The conveyor system of claim 2, said bearing assembly including a pair of bearings supporting the shaft in a cantilevered manner. ### Claim 4 (depends on 3) The conveyor system of claim 3, each of said bearings being a unit bearing. ### Claim 5 (depends on 1) The conveyor system of claim 1, said power assembly comprising a motor assembly, said power source comprising a motor. ### Claim 6 (depends on 1) The conveyor system of claim 1, said drive comprising a pulley drive. ### Claim 7 (depends on 6) The conveyor system of claim 6, said power source including an output shaft rotatable about an axis, said pulley drive including— a drive pulley fixed to the output shaft to rotate therewith, a driven pulley spaced from the drive pulley and secured relative to the roller to rotate therewith, and a drive belt extending between and operably connecting the drive pulley and the driven pulley, such that driven rotation of the drive pulley by the output shaft results in rotation of the driven pulley, rotation of the roller, and shifting of the conveyor belt. ### Claim 8 (depends on 7) The conveyor system of claim 7, said pulley drive being devoid of a tensioner. ### Claim 9 (depends on 1) The conveyor system of claim 1, said shell being removably mounted to the chassis. ### Claim 10 (depends on 1) The conveyor system of claim 1, said chassis defining a bearing support structure, said power assembly including a bearing assembly received within the bearing support structure. ### Claim 11 (depends on 1) The conveyor system of claim 1, said conveyor system further including a moveable vehicle, said conveyor assembly being mounted to said vehicle. ### Claim 12 (depends on 11) The conveyor system of claim 11, said conveyor belt being supported above an upper surface of the vehicle. ### Claim 13 (depends on 12) The conveyor system of claim 12, said chassis being secured to the upper surface of the vehicle. ### Claim 14 (depends on 11) The conveyor system of claim 11, said vehicle being a powered vehicle. ### Claim 15 (depends on 14) The conveyor system of claim 14, said vehicle being an autonomous guided vehicle. ### Claim 16 (depends on 1) The conveyor system of claim 1, said roller including a tubular main body and an insert extending outwardly from said main body. ### Claim 17 (depends on 16) The conveyor system of claim 16, said conveyor assembly further including a roller bearing, said roller bearing rotatably supporting said insert. ### Claim 18 (depends on 1) The conveyor system of claim 1, said roller being a drive roller, said conveyor assembly further including an additional roller spaced from said drive roller, said conveyor belt extending endlessly around said drive roller and said additional roller.
