摘要： A pump includes an electric motor with a rotor rotatably mounted about an axis of rotation and circumferentially surrounding a stator. The stator includes a stator core and coils wound on the stator core. The windings are made of a winding wire including winding wire end portions which are electrically contacted with a circuit board on an end side. The rotor, the stator, and the circuit board are surrounded by a motor housing which is adjoined by a pump housing, the circuit board being electrically contacted with an intermediate plug to contact the circuit board with an electrical controller. The intermediate plug includes contacts which are injection-molded into the intermediate plug, are electrically contacted with a first end at the circuit board, include a second end arc directed at least partially radially outwardly, and are introduced into a connecting region of the intermediate plug.

摘要： A plug-in coolant pump for motor vehicles includes an impeller surrounded by a pump housing. The impeller can be driven about a longitudinal axis extending through the pump housing by a pump shaft. A seal is provided between the pump shaft and the pump housing to seal the coolant-carrying pump housing, wherein the pump housing includes retaining domes on which a sealing disc is fastened which sets a sealing gap between a pump inlet with a pressure slope and the open impeller.

摘要： An electric coolant pump is used as an auxiliary water pump in a vehicle. The pump includes radial mounting of the shaft (4) is provided by means of a coolant-lubricated radial sliding bearing (41) arranged between the pump impeller (2) and the rotor (32). A dry-running electric motor (3) with a radially inner stator (31) and a radially outer rotor (32) is accommodated in a motor chamber (13) separated from the pump chamber (10). A shaft seal (5) is between the radial sliding bearing (41) and the motor chamber (13). The rotor (32) is bell-shaped with an inner surface facing the shaft seal (5) and being fixed to the shaft seal (5) to axially overlap with the shaft (4). The motor chamber (13) has an opening to the atmosphere, which is closed by a liquid-tight pressure equalization membrane (6) that is permeable to vapor.

摘要： In producing tooth shapes of two toothed rings of an annular gear machine, a starting geometry of a first toothed ring, at least one quality criterion of the annular gear machine, and a desired eccentricity between rotational axes of the two toothed rings are defined. A motion is performed with the starting geometry that performs a rotational motion about its rotational axis and a revolving motion about the rotational axis of the second toothed ring. The rotational and revolving motions are coupled so the rotational angle of the eccentricity equals the product of the rotational angle and tooth count of the first toothed ring. A tooth shape contour of the second toothed ring is generated by recording the path described by the envelope of the starting geometry. If the defined quality criterion is not met, the previously used starting geometry and/or the defined eccentricity is changed and steps are repeated.
