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.

Transmission having a fan assembly

A transmission includes a fan assembly having a fan wheel, a cover, and a grating. The fan wheel is connected in a torsionally fixed manner to the input shaft of the transmission, and the fan cover is fixed in place on a holding frame, which, for example, includes multiple parts and is fastened to the housing of the transmission. The grating is formed by two grating parts, whose first separating line is a straight segment or is formed by two mutually aligned straight segments, and the cover includes two cover parts, whose second separating line is a plane curve, made up of straight segment sections.

A gear unit includes a shaft, in particular an input shaft, a flange part and a housing part. The input shaft is supported by bearings in the housing part, and a fan is connected to the shaft in a torsion-proof manner. The housing part includes cooling fins, in particular cooling fins that extend in the axial direction, i.e. in the axis direction of the shaft, the cooling fins have an offset and/or stepped configuration, and the flange part surrounds the offset or stepped region of the cooling fins, in particular in the manner of a housing.
