摘要： The invention relates to an internal geared wheel pump without a filler piece, comprising a housing, an internal geared wheel (3) which rotates in the housing and an external geared pinion (2) which is rotationally mounted in the housing and which meshes with the geared wheel. The teeth of the pinion define a suction area and a pressure area in the gearing, by complete engagement with the tooth spaces of the geared wheel and by sealing contact with tooth crowns of the geared wheel in an engagement-free geared wheel area which lies approximately diametrically opposite the tooth space engagement. The toothing of the geared wheel and the pinion is an involute or cycloid toothing, the tooth crowns having a rounded peripheral surface (23, 34). The tooth crowns of the geared wheel (3) and/or the pinion (2) are asymmetrically rounded in relation to a centre line (40) of each tooth (22, 33), in such a way that a transition line (42) between the tooth face (24, 35) and the peripheral surface (41) is located on the rear tooth face (35) (in the direction of rotation) for the geared wheel and on the front tooth face (24) (in the direction of rotation) for the pinion, closer to the tooth base than on the opposite tooth face, respectively.

摘要： Described is an internal-gear machine (10) comprising a casing (12, 80) in which there are provided an internally toothed annular gear (20), an externally toothed pinion (24) in engagement therewith, and a filling portion (28) which is divided into two in the space (14) between the annular gear (20) and the pinion (24). The filling portion parts (32, 34) are provided with openings (56, 58) which start from the common separation surface (30) and which are each provided with an inclined surface (60, 62) that is parallel to the axis, in such a way that the two inclined surfaces (60, 62) which face towards each other form with each other wedge surfaces which include a wedge angle. Bearing against the wedge surfaces is a respectively associated sealing roller (64) which is pressed against the associated wedge surfaces by means of a spring element (88). In order to provide a resilient springing characteristic which is as soft as possible and thereby to afford optimum stabilization in respect of the radial forces involved and a considerable reduction in noise, it is proposed that the corresponding spring element (88) is fixed with a fixing portion (92) to a securing portion (96) of the casing. A spring portion (90) of the corresponding spring element (88) projects away from the fixing portion (92), said spring portion being oriented at least approximately parallel to the axis and pressing against the associated sealing roller (64).

摘要： An internal gear fluid machine includes a first gearwheel having an external toothing and mounted rotatably about a first axis of rotation, and a second gearwheel having an internal toothing meshing in regions with the external toothing in an engagement region and mounted rotatably about a second axis of rotation different from the first axis of rotation. The internal gear fluid machine additionally includes a filler piece arranged between the first gearwheel and the second gearwheel away from the engagement region, which filler piece bears on one side against the external toothing and on the other side against the internal toothing, in order to divide a fluid space present between the first gearwheel and the second gearwheel into a first fluid chamber and a second fluid chamber. Sealing discs are arranged in the axial direction with respect to the first axis of rotation on both sides of the first gearwheel and the second gearwheel, which, during operation of the internal gear fluid machine, bear in a sealing manner against the first gearwheel and the second gearwheel, and an axial opening is formed in each of the sealing discs. A common one of the fluid chambers is in flow communication with the same fluid connection of the internal gear fluid machine via both axial openings.
