Abstract (en)
[origin: EP1132620A2] The gear is constructed for angled drive. The conical pinion (3) on the input shaft (2) meshes with the conical wheel on the output shaft (5). An additional toothed wheel (10) is assembled onto the input shaft, forming a gear pump with a second toothed wheel. This transfers fluid against the operational rotation of the gear. Preferred Features: One pump chamber (15) of the gear pump is below the fluid level. The other pump chamber is connected via a restriction (17) above the fluid level with the oil-filled interior.
