Abstract
A drum motor has a drum motor shell having a hollow space therein, a rotor and a stator, and bearing journals in the drum motor shell, the rotor and the stator being mechanically coupled to the drum motor shell and the bearing journals in such a way that relative rotation between the rotor and the stator causes relative rotation between the drum motor shell, and the bearing journals. 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 has a polygonal, preferably hexagonal inner recess.
Claims10
A drum motor for driving a conveyor belt, in particular a modular belt in hygienic surroundings involving exposure to splash water and pressurized water, 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 at a first end of the drum motor shell, and
- a second bearing journal arranged at a second end of the drum motor shell,
- the rotor and the stator being mechanically coupled to the drum motor shell and to the first and second bearing journals in such a way that relative rotation between the rotor and 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 drum motor shell having at least one torque transfer section in which the outer surface of the drum motor shell is polygonal in cross-section,
- characterized in that the inner surface of the drum motor shell (110) in the torque transfer section is polygonal in cross-section.
