Definitions
- the invention relates to a gearless roller drive, which is intended to be installed in a hollow cylindrical roller in order to drive these rotating.
- Roller drives are used for example in conveyor systems such as conveyor belts or roller conveyors, but also, for example, in shutters, disturbances and the like.
- roller drives with gearboxes known in
- the present invention seeks to propose a gearless roller drive, the simple and inexpensive to produce and a wide torque and speed range with a high continuous power and a high number of
- Load cycles can be used.
- Roller drive comprises an electric control unit and that the transverse flux motor and the control unit are arranged axially one behind the other.
- transverse flux motor allows due to its basic structure a relatively high thermal load and thus a high continuous power and a high number of load cycles per unit time.
- the drive can be delivered ready for connection through the control unit located in the drive.
- Another advantage is that such a roller drive can be controlled without a torque sensor, because transverse flux motors show a large change in current when load changes.
- the dimensions of the control unit do not exceed the rotor diameter radially relative to the stator axis. This makes it possible to accommodate the control unit completely in a hollow cylindrical roller.
- control unit is designed such that it can be used as a closing element in a hollow cylindrical roller.
- a part of the control unit protrude from the roll and the
- control unit has an axial opening into which the stator axis
- Stator axis are held. After an additional embodiment, the penetrates
- Stator axis the control unit.
- a roller drive can be realized in which the stator axis can be supported at both ends of the roller.
- Control unit with at least one in a central
- the control unit is provided with at least one in a longitudinal groove of the stator axis
- stator and the rotor have two or more axially successively arranged pole units.
- the polar units are in
- At least one radially resilient tolerance ring is on the outside of the rotor
- the roller drive has at least one fitting piece for the front end of a hollow cylindrical roller, its assembly is further simplified.
- the fitting is with
- Sealant equipped to protect the roller drive from dirt and liquid.
- the sealing means are designed as labyrinth sealing means. Such seals are wear-free during operation.
- Transversal letmotoren are arranged one behind the other. This allows on the one hand a multiplication of the drive power, whereby the individual transverse flux motors can be operated absolutely synchronously. On the other hand, it is also possible, individual coaxially arranged one behind the other

- Each stator pole unit 4 includes two toothed pulleys 5, a flow tube 6 connecting them and a coil 7 surrounding the flow tube 6.
- One tooth each of a pair of stator pole units 4 includes two toothed pulleys 5, a flow tube 6 connecting them and a coil 7 surrounding the flow tube 6.
- Toothed disks 5 forms with a portion of the
- Each stator pole unit 4 is surrounded by a rotor pole unit 8, which consists of one another in the circumferential direction
- the 'three rotor pole units 8 are surrounded by a tubular casing 18, which is on both sides of the stator and rotor pole units 4, 8 via roller bearings 11, rotatably supported on the stator 10 12th To bridge a diameter difference between the outer diameter of the rolling bearings 11, 12 and the
- Bearing transition rings 13, 14 may be provided.
- the three arranged in the longitudinal axis 3 in succession, encompassed by the jacket tube 18 rotor pole units 8 form the rotor of the transverse flux.
- FIG. 1 to the right of the stator and rotor pole units 4, 8, there is a control unit 15 on the stator axis 10
- control unit 15 comprises a frequency converter in order to be able to operate the transverse flux motor at desired speeds in accordance with its number of poles.
- the electrical connections of the control unit 15 will be explained below with reference to FIGS. 3 to 5.
- the control unit 15 may have a central opening, so that the stator axis 10 can completely penetrate the control unit 15 and protrude from the roller 2 on both sides.
- a coupling axis 16 is connected to the stator axis 10 by means of a coupling 21.
- a press-fit sleeve 17 connects the jacket tube 18 with the roller 2 and is rotatable by two rolling bearings 23 on the
- Figure 2 shows in a perspective exploded view another embodiment of a gearless
- roller drive according to the invention. Links in the figure, a clamping ring 31 is shown, which serves for the axial securing of the rolling bearing 11 on the stator 10.
- Bearing transition ring 13 serves to bridge the

- Control unit 15 equipped with a central opening so that it can be plugged onto the stator 10.
- plug-in couplings 29 are present, which are connectable to the plug contacts 28.
- FIG. 3 shows a simplified longitudinal section through the stator of the transverse flux motor, wherein it is particularly clear how conductors 25 for supply and control are plugged through a central bore 26 in the stator axis 10 to the right end of the stator axis 10 in the figure
- Leading from the control unit 15 lead 24 to the three coils 7.
- Terminal conductors 24 are guided by the longitudinal grooves 27, as will become apparent hereinafter with reference to FIG. 4.
- the aforementioned bearings 11, 12 are arranged in both end portions of the stator 10.
- Figure 4 shows a cross section through the
- Transverse flux motor wherein from the inside to the outside guided through the central bore 26 of the stator 10 and conductor 25 in the longitudinal grooves 27 of the stator 10th

- FIG. 5 shows, in a perspective exploded view, the end of the stator axis 10, which protrudes to the right from a rotor pole unit 8.
- Stator 10 pushed and can be connected by means of the plug contacts 28 and 28 plug-in couplings.
- FIG. 6 shows a further embodiment of the invention
- roller drive In this example, two independent transverse flux motors are on one
- Everybody has
