Abstract (en)
[origin: WO2019052871A2] The invention relates to a motor-driven conveying roller (1) for conveying systems for conveying containers, pallets and the like, comprising a drum tube (2) having a cavity formed therein and a longitudinal axis (A), a shaft (4) running in the longitudinal axis (A) and on which the drum tube (2) is mounted by means of at least one rotary bearing (6), and an electric drive unit (14) arranged in the cavity. The invention is characterized by a cooling sleeve (30) which is fastened radially internally to the drum tube (2) and surrounds at least partially the drive unit (14) in a radial manner, so that a radial air gap (S) is formed between drive unit (14) and cooling sleeve (30). The invention further relates to a production method for such a conveying roller.
