Patent ID: 7926377

Claim:
An industrial robot bevel gearing with a housing comprising: a first conical gear wheel with an axis of rotation (A) of the first conical gear wheel; a second conical gear wheel with an axis of rotation (I), which forms a right angle with the axis of rotation (A) of the first conical gear wheel; a first drive shaft having a longitudinal length which is fixedly arranged with the first conical gear wheel; a first device for adjusting the backlash in the bevel gearing, said first device comprising a first holder member; said first holder member receives and rotatably journals the first drive shaft by means of contact bearing members disposed between an inner surface of the first holder member and an outer surface of the first drive shaft, and is arranged displaceable in a direction (C), which is parallel to the axis of rotation (I) of the second conical gear wheel; said first gear wheel is displaceable in the direction (C) in parallel with the axis of rotation (I) of the second conical gear wheel; wherein the first holder member is guided for linear displacement in the direction (C) in a passage formed in the housing and extending along a length of said first drive shaft and being formed for linear guiding of the first holder member, and by means of a fixing joint is fixed in a desired position in which a backlash is adjusted.
