Patent number: 8782894Abstract: A method for producing and commissioning a transmission with a water-based lubricant comprises the following steps. A mixture of a vaporizable liquid, a comminuted solid lubricant and a preserving agent (22) are applied (21) to the finished rotary parts (20) and then dried (23), whereby a coating forms on them. The rotary parts with the coating are installed in the transmission housing and the assembled transmission is filled with a cooling liquid (25), which is primarily essentially water. The transmission is put into operation for the first time (27), wherein the lubricant for the further operation is only formed by abrasion of the rotary parts and distribution of the abraded matter in the cooling liquid. The transmission is then ready for operation (28). Furthermore, a lubricant produced by this method is described.Type: GrantFiled: October 12, 2009Date of Patent: July 22, 2014Assignee: MAGNA STEYR Fahrzeugtechnik AG & Co.

Patent number: 8651745Abstract: In an electrical machine having a roller bearing, whose inner ring is seated on the rotor shaft of the electrical machine, whose outer ring is seated in a housing and which is located in a closed area, the roller bearing is intended to be protected against electrical breakdowns. For this purpose, the area contains a liquid on an aqueous basis, whose level overhangs the external contour of the inner ring at its lowest point. The inner ring and the outer ring are therefore conductively connected and the voltage can be equalized between the rotor and the housing of the electrical machine, without any impediment and without breakdowns. In an application as a geared motor, the lubricant for the gearbox is also a liquid on an aqueous basis.Type: GrantFiled: August 10, 2010Date of Patent: February 18, 2014Assignee: MAGNA STEYR Fahrzeugtechnik AG & Co.
