Abstract

The invention proposes in gear ring pumps for reciprocating internal-combustion engines and/or automatic transmissions allowing the hollow gear to run in the hollow gear housing with a play which is large enough for the pronounced fluctuations of the radial position of the crankshaft or input shaft carrying the pinion of the gear ring pump to be taken up thereby and selecting a toothing for the pump such that the effective mounting of the hollow gear on the pinion is achieved.
If a correspondingly large play is provided between the shaft and the pinion, the hollow gear is mounted with minimum play in the housing. The pinion is then mounted in the hollow gear.
