Abstract: The invention relates to a marine-vessel transmission having an input-drive shaft (10), which extends along an input-drive shaft axis (A) and on which an input-drive shaft gearwheel (12) is arranged, a first pinion shaft (14), which extends coaxially with respect to the input-drive shaft (10) and on which a first pinion (16) is arranged, a second pinion shaft (24), which extends parallel to the input-drive shaft (10) and on which a pinion shaft gearwheel (28), which engages with the input-drive shaft gearwheel (12), and a second pinion (26) are arranged, an intermediate shaft (18), on which a spur gear (20), which engages with the first pinion (16) and the second pinion (26), and a bevel pinion (22) are arranged, and an output-drive shaft (30), which extends along an output-drive shaft axis (P) which runs at an angle (?) of more than 75° with respect to the input-drive shaft axis (A), and on which a spur bevel gear (31) is arranged, which forms a bevel drive with the bevel pinion (22).

Abstract: The invention relates to a mid-frequency high power transformer which is specially used as a welding transformer in resistance welding, comprising a primary winding penetrated by the limb of a transformer core and a secondary winding which are configured as concentrically overlapping cylindrical windings. The windings of the primary windings are formed by a plurality of spirally wound layers of a relatively thin electrically conductive metal strip material, and the windings of the secondary winding are formed by an appropriate number of spirally wound layers of a thicker electrically conductive metal strip material chosen according to the desired reduction ratio between the primary and the secondary windings.
