Abstract
A drive for a transport device, such as a conveyor belt, the drive including an external rotor motor having a stator and a rotor, and a gear unit having a shaft and an input drive gear. A set of drives in which external rotor motors of different sizes, including stators of identical diameter and different heights with corresponding rotors, and/or gear units having different speed-increasing stages or speed-reducing stages, are provided. Also, a method for driving a transport device using the drive.
Claims35
A drive for a transport device said drive comprising:
- an external rotor motor comprising a stator and a rotor,
- a gear unit comprising a shaft and an input drive gear, wherein the shaft extends through the stator and up to the rotor, and
- a double bearing provided in the gear unit, wherein the double bearing comprises two spaced-apart bearings being arranged along the longitudinal axis of the shaft within the gear unit,
- the rotor being arranged on the shaft and being configured such that it is connectable to the shaft, in a form- and/or force-fit manner, by means of at least one of a group comprising a fitting key, a cone, and a fit,
- the double bearing for the shaft being provided in the gear unit by making use of angular contact ball bearings, so as to ensure that forces of a brake will be taken up.
