摘要： The compressor machine has two rotors rotating in opposite directions, which are fitted to two parallel, spaced apart shafts mounted in a housing. One of the shafts is driven directly and the other by intermeshing toothed gears mounted on the shafts. The housing has two radial walls which are configured in one piece with each other and with a peripheral wall and in which the shafts are mounted. The toothed gears are arranged between these radial walls. A side wall of the housing has an opening sealed by a removable cover. With the cover removed, the toothed gears can be fitted to the shafts through these openings. The bearing bores for the shafts can be produced and machined in the one-piece housing in a single set-up, so that, with a minimum number of parts, any causes of alignment errors are avoided.

摘要翻译： 压缩机具有两个沿相反方向旋转的转子，它们安装在安装在壳体中的两个平行的间隔开的轴上。 其中一个轴直接驱动，另一个轴通过安装在轴上的齿形齿轮相互啮合。 壳体具有两个径向壁，它们彼此成一体并且具有周壁，并且其中安装有轴。 齿形齿轮布置在这些径向壁之间。 壳体的侧壁具有由可移除的盖子密封的开口。 在拆下盖子的情况下，齿轮可以通过这些开口装配到轴上。 用于轴的轴承孔可以在单件壳体中以单个装置生产和加工，使得在最少数量的部件的情况下，避免了任何对准误差的原因。

摘要： A rotary piston pump has at least two rotors (8) with associated drive shafts (26), wherein for each rotor (8) an associated bearing tube (28) is provided, which extends into the associated rotor (8) and through which the associated drive shaft (26) passes. Between the inside (24) of each rotor (8) and the outside of the bearing tube (28) a first gap (64) is provided. In operation, the first gap (64) contains cooling fluid and is part of a cooling fluid circuit.
