| 摘要 |
The invention relates to a drum motor for driving a conveyor belt, comprising a drum motor shell having a hollow space therein, motor components arranged in said hollow space, namely a rotor and a stator, a first bearing journal arranged on a first end of the drum motor shell and a second bearing journal arranged on a second end of the drum motor shell, the rotor and the stator being mechanically coupled to the drum motor shell and the first and second bearing journals in such a way that relative rotation between the rotor and the stator causes relative rotation between the drum motor shell, for the one part, and the first and second bearing journals, for the other part. The invention also relates to a sprocket for transferring a torque from a drum motor to a modular belt. The drum motor is characterised in that the drum motor shell has at least one torque transfer section in which the outer surface of the drum motor shell is polygonal in cross-section. The sprocket of the invention is characterised in that the sprocket has a polygonal, preferably hexagonal inner recess. |
