Abstract
A transmission includes a fan assembly, including a fan wheel, a hood, and a guard. The fan wheel is connected to the driving shaft of the transmission for conjoint rotation, and the hood is attached to a, e.g., multi-piece retaining frame fastened to the housing of the transmission. The guard is formed of two guard parts, and the first parting line thereof is a straight segment or formed of two straight segments in alignment with each other. The hood is formed from two hood parts, and the second parting line thereof is a flat curve including straight line segments.
Claims28
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;
- wherein the guard includes the first guard part and the second guard part, each of the first guard part and the second guard part connected to each of the two hood parts.
