Definitions
- the housing 11 comprises a carrier housing 12, on which an eccentric to the axis of a drive shaft 15 extending collar is formed, and a support housing 12 mounted in the pump housing 13.
- the pump housing 13 is stored in the pump raceway area 38 or in the region of a bearing journal 36 without play in the carrier housing 12 of the two-part housing 11.
- a ring gear which with a preferably non-positively in the form of a shrink fit or press fit on the drive shaft 15 rotatably mounted gear 16, which is also referred to as a pinion, meshes.
- Front side is located in front of the pump housing 13, the ring gear 14 of the end face of the drive shaft 15 and the gear 16, a pump cover 17.
- the pump cover 17 in turn is centered by means of a cup-shaped closure cap 18 and the just mentioned bundles of the carrier housing 12 of the housing 11 by means of a flanging 24 - as in FIG. 1 shown - attached.
- the bearing pin 36 is mounted in an eccentric 37 with respect to the support housing 12, the inner pump housing 13 can not be rotated.
- the pump housing 13 is axially free of play between the support housing 12 and the pump cover 17 built to prevent hydraulic losses by additional axial column.
- FIG. 3 is a section according to the CD in the illustration according to FIG. 2 refer to.
- a significant advantage of the delivery unit 10 proposed according to the invention results from the use of materials with the same thermal expansion as possible. Conveying units 10 made of such materials, in particular internal gear pumps, can then be used for a very broad temperature range without significantly changing the clearance of the movable pump components that is decisive for the sealing gaps. As a result, a good hydraulic efficiency of the delivery unit 10 is always ensured, further a quiet Laufund a good lubrication.
