ABSTRACT:
The low-loss pinion drive has a housing (2) in which the gear wheels are fitted in radial bearings (3) and preferably also an additional inner housing (4) enclosing the pinions (1) as closely as possible. At least the air and preferably also the lubricating and cooling oil can be evacuated from the inner casing chamber (9). The air is evacuated by a pump which is also suitable for removing the oil. The air can be replaced by a gas of substantially lower density than air.
