Abstract: A motor-driven conveyor roller for conveyor systems for conveying containers, pallets, and the like, includes a drum tube with a cavity formed therein and a longitudinal axis, a shaft which extends in the longitudinal axis and on which the drum tube is supported by at least one bearing, and an electric drive unit arranged in the cavity. The motor-driven conveyor includes a cooling sleeve which is fixed radially inwardly to the drum tube and at least partially radially surrounds the drive unit so that a radial air gap is formed between the drive unit and the cooling sleeve. The disclosure also relates to a manufacturing process for such a conveyor roller.

Abstract: A motor-driven conveying roller for conveying installations for conveying containers, pallets and the like, having a roller body, of which the outer circumferential surface constitutes a bearing surface for articles, having a drive unit, which is arranged within an interior of the roller body, and having a coupling unit, which is designed to transmit a torque from the drive unit to an inner circumferential surface of the interior of the roller body and has a coupling bushing, which has a drive portion, connected to the drive unit, and an outer peripheral output portion, wherein the coupling bushing is connected to the inner circumferential surface of the roller body in a frictionally fitting and/or integral manner, for torque-transmitting purposes, only at certain points.

Abstract: The invention relates to a motor-driven conveyor roller (1) for conveyor systems for conveying containers, pallets and the like, comprising a drum tube (2) with a cavity formed therein and a longitudinal axis (A), a shaft (4) which extends in the longitudinal axis (A) and on which the drum tube (2) is supported by means of at least one bearing (6), and an electric drive unit (14) arranged in the cavity. The invention is characterized by a cooling sleeve (30) which is fixed radially inwardly to the drum tube (2) and at least partially radially surrounds the drive unit (14) so that a radial air gap (S) is formed between the drive unit (14) and the cooling sleeve (30). The invention also concerns a manufacturing process for such a conveyor roller.

Abstract: A drift conveyor (1) has rollers (14) introduced into bearings (13) of a frame (12). An axle (143) of the roller (14) is received in a receptacle (1310) of the bearing (13), and a roller plate (15) presses the bearing (13) so that a first sealing region (1308) of the bearing (13) contacts a sealing region (152) of the roller plate (15). A rotary fastening region of the bearing (13) contacts a fastening region (153a) of the roller plate (15) and a second sealing region of the bearing (13) contacts the frame sealing region. One side of the bearing (13) has the receptacle (1310), the first sealing region (1308) and a rotary fastening region that prevents rotation of the bearing (13) with respect to the roller plate (15). An opposite side of the bearing (13) has a second region for sealing between the bearing (13) and the frame (12).
