Abstract

A motor-driven conveyor roller comprises a conveyor roller tube, a first axle unit inserted into a first end of the conveyor roller tube, a first bearing unit at the first end, around which the conveyor roller tube is mounted so as to be correspondingly rotatable around the first axle unit, a drive unit, and a first gearing arranged in the conveyor roller tube and which transmits a torque, generated by the drive unit, between the conveyor roller tube and the first axle unit.

An end cap is connected fixedly in terms of torque to the conveyor roller tube at the first end and to which the first gearing is connected fixedly in terms of torque at a first gearing connection section of the end cap, wherein the end cap has a second gearing connection section, which is different from the first gearing connection section.

Claims

1-17. -17. (canceled)

18. A motor-driven conveyor roller comprising:

a conveyor roller tube;

a first axle unit inserted into a first end of the conveyor roller tube;

a first bearing unit at the first end around which the conveyor roller tube is mounted so as to be correspondingly rotatable around the first axle unit;

a drive unit; and

a first gearing arranged in the conveyor roller tube and which transmits a torque generated by the drive unit between the conveyor roller tube and the first axle unit;

wherein an end cap is connected fixedly in terms of torque to the conveyor roller tube at the first end and to which the first gearing is connected fixedly in terms of torque at a first gearing connection section of the end cap, and wherein the end cap has a second gearing connection section which is different from the first gearing connection section.

19. The conveyor roller as claimed in claim 18, wherein the first gearing connection section provides a force-fitting connection fixed in terms of torque to the first gearing.

20. The conveyor roller as claimed in claim 18, wherein the second gearing connection section provides a non-force-fitting connection fixed in terms of torque to a second gearing which is different from the first gearing and is adapted to be mounted instead of the first gearing in the conveyor roller tube.

21. The conveyor roller as claimed in claim 20, wherein the second gearing connection section provides a form-fitting connection fixed in terms of torque to the second gearing.

22. The conveyor roller as claimed in claim 18, wherein when the first gearing is connected to the first gearing connection section, the second gearing connection section does not interact with the first gearing for torque transmission.

23. The conveyor roller as claimed in claim 18, wherein the first gearing connection section is formed by a cylindrical peripheral surface that forms a press fit with a cylindrical peripheral surface of the first gearing.

24. The conveyor roller as claimed in claim 23, wherein the second gearing connection section has an axial surface or a peripheral surface having at least one projection or one depression.

25. The conveyor roller as claimed in claim 18, further comprising:

a second axle unit inserted into a second end, opposite the first end, of the conveyor roller tube; and

a second bearing unit at a second end of the conveyor roller tube, which is fastened in a second end cap, the second end cap being of identical design to the first end cap and fastened in the conveyor roller tube mirror symmetrically with respect to the first end cap relative to a central cross-sectional area of the conveyor roller tube.

26. The conveyor roller as claimed in claim 18, further comprising a first seal element disposed between the first axle unit and the first end cap and which is fastened in the first end cap.

27. The conveyor roller as claimed in claim 18, wherein the first gearing has a motor connection flange and is coupled by means of the motor connection flange to a motor arranged in the conveyor roller tube.

28. A conveyor roller system having a conveyor roller comprising:

a conveyor roller tube;

a first axle unit inserted into a first end of the conveyor roller tube;

a first bearing unit at the first end around which the conveyor roller tube is mounted so as to be correspondingly rotatable around the first axle unit;

a drive unit; and

a first gearing arranged in the conveyor roller tube and which transmits a torque generated by the drive unit between the conveyor roller tube and the first axle unit;

wherein an end cap is connected fixedly in terms of torque to the conveyor roller tube at the first end and to which the first gearing is connected fixedly in terms of torque at a first gearing connection section of the end cap, and wherein the end cap has a second gearing connection section which is different from the first gearing connection section;

the conveyor roller system further comprising a second gearing having a connection region which forms, with the second gearing connection section, a connection fixed in terms of torque.

29. The conveyor roller system of claim 28, where the connection formed by the second gearing transmits torque by means of a form fit.

30. The conveyor roller system as claimed in claim 28, wherein:

the second gearing connection section of the end cap has an axial surface or a peripheral surface having at least one projection or one depression, and the connection region of the second gearing has a depression or a projection which is disposed against the projection or the depression of the end cap for torque transmission.

31. The conveyor roller system as claimed in claim 28, wherein the first gearing has a first connection region, which consists of a metallic material and interacts with the first gearing connection section, and the second gearing has a second connection region, which consists of a polymer material and interacts with the second gearing connection section.

32. The conveyor roller system as claimed in claim 28, wherein the first gearing has a first motor connection flange and the first gearing is adapted to be coupled by the first motor connection flange to a motor arranged in the conveyor roller tube, and the second gearing has a second motor connection flange, which is compatible with the first connection flange, and the second gearing is adapted to be coupled by the second motor connection flange to the motor arranged in the conveyor roller tube.

33. A motor-driven conveyor roller comprising:

a conveyor roller tube;

a first axle unit inserted into a first end of the conveyor roller tube;

a first bearing unit at the first end around which the conveyor roller tube is mounted so as to be correspondingly rotatable around the first axle unit;

a drive unit;

a first gearing arranged in the conveyor roller tube and which transmits a torque generated by the drive unit between the conveyor roller tube and the first axle unit; and

a second gearing having a connection region that forms, with the second gearing connection section, a connection fixed in terms of torque;

wherein an end cap is connected fixedly in terms of torque to the conveyor roller tube at the first end and to which the first gearing is connected fixedly in terms of torque at a first gearing connection section of the end cap, and wherein the end cap has a second gearing connection section which is different from the first gearing connection section; and

34. A method for producing a motor-driven conveyor roller, comprising the steps of:

providing a conveyor roller tube having a first and a second end
