Claim 27:
28. A transmission, comprising:
a fan assembly including a fan wheel connected to a driving shaft of the transmission for conjoint rotation, a hood attached to a retaining frame fastened to a housing of the transmission and formed of a first hood part and a second hood part, and a guard; and
a cover part adjacent to the first hood part and supported and/or retained by at least one tab connected to the housing of the transmission and/or attached to the housing of the transmission;
wherein a region covered by the cover part in an axial direction is spaced apart from a region covered by the first hood part in the axial direction or is adjacent thereto;
wherein the axial direction is a direction of an axis of rotation of the driving shaft;
wherein the hood and the cover part are arranged such that a portion of an air stream transported by the fan wheel is guided between the housing of the transmission and the cover part by the hood and the cover part;
wherein a circumferential angle range covered by a first guard part in a circumferential direction is adjacent to, but not overlapping, a circumferential angle range covered by a second guard part in the circumferential direction;
wherein a circumferential angle range covered by the first hood part in the circumferential direction is adjacent to, but not overlapping, a circumferential angle range covered by the second hood part in the circumferential direction;
wherein a circumferential angle range covered by the first guard part in the circumferential direction overlaps the circumferential angle range covered by the first hood part; and
wherein a first parting line between the guard parts is arranged as a straight line or as two straight lines aligned with each other, a second parting line between the first hood part and the second hood part is arranged as a flat curve including straight line segments, the first parting line and an axis of rotation of the driving shaft defining a first plane, the second parting line and the axis of rotation of the driving shaft defining a second plane, the second plane is oriented perpendicular or at an angle between 30° and 90° to the first plane.
