Abstract: A method for pressing a reinforcing sleeve onto a rotor of an electric motor, including: affixing a press ring having a stop to the reinforcing sleeve so that the stop abuts an end face of the reinforcing sleeve, and at least one annular and/or ring-segment-shaped section of the press ring embraces at least one annular and/or ring-segment-shaped section of the reinforcing sleeve that terminates at the end face of the reinforcing sleeve; and pressing the reinforcing sleeve onto the rotor, the reinforcing sleeve being centered relative to the rotor so that a longitudinal axis of the reinforcing sleeve is aligned with a longitudinal axis of the rotor, and a pressing force being applied to the pressing ring affixed to the reinforcing sleeve.

Abstract: A method and a device for joining a reinforcement sleeve onto a rotor of an electric motor. The method includes providing the reinforcement sleeve and the rotor, the reinforcement sleeve has a cylindrical inner periphery which is undersized with respect to a cylindrical outer periphery of the rotor; attaching at least two vacuum cups onto an outer lateral surface of the reinforcement sleeve, such that the vacuum cups adhere to the outer lateral surface of the reinforcement sleeve in a reversibly detachable manner on account of a vacuum generated between the vacuum cup and the outer lateral surface; and joining the reinforcement sleeve onto the rotor, in that the rotor is pressed into the reinforcement sleeve in a pressing direction.

Abstract: A heatable liquid container made from plastic material, particularly for holding water/urea mixtures and having an internal cavity and a heating element arranged essentially in the internal cavity of the container, and with at least one connection end, the heating element is braced by a bracing element in at least one bearing area in the internal cavity of the liquid container. The heating element is supported in a horizontally floating manner by the bracing element. The bracing element is an insert part that is at least partially encased in the plastic material by sintering and is made from the same material as the inner wall of the liquid container.

Abstract: The invention relates to an assembly device (1) and to a method to reliably mount containers (3) fitted with a self-supporting structure (4), in particular plastic containers (3) for liquid media and chemicals such as liquid engine-fuels, for affixation on stationary or displaceable supports (2). The method comprises the steps: affixing conduits to a support (2); affixing the container (3) on the support (2); and connecting the container (3) to the conduits; where the step of assembling the container (3) to the support (2) includes affixing one connector part (8) each on the support (2) and on the container (3) as well as joining to each other the connector parts (8). Preferably the connector part (8) shall be affixed on the support (2) before the step of affixing the conduits. The assembly device (1) comprises means with which to carry out said method.
