摘要:
A high-pressure pump having a drive shaft and at least one pump element including a pump piston driven in a reciprocating motion by the drive shaft. A ring on which the pump piston is braced via a support element is rotatably supported on a portion of the drive shaft that is disposed eccentrically to its pivot axis. The ring and/or the support element, at least in their contact region, has many microscopic indentations, and a solid lubricant film is applied to the ring and/or to the support element, at least in their contact region.

摘要:
A component having a layer system situated on the component is described, for increasing the resistance to wear of the component. The layer system in this context includes a phosphate layer and particles of solid lubricants, the layer system being free of any binding agent. A method for producing such a component is also described.
摘要:
The invention pertains to a plain porous bearing for motors and transmissions with a circular bearing bore that displays, distributed alternatingly across the bearing bore, highly compressed at least approximately closed-pore areas and slightly compressed, open-pore areas, where the bearing bore diameters of the highly and slightly compressed areas are at least approximately identical. Also provided is a procedure and device for production of the bearing.
摘要:
A method for redundantly operating an automation system comprising one or more user computers, at least two gateway computers and a plurality of programmable logic controllers, the user computers and the gateway computers being connected to a first bus system of a first type and the gateway computers and the programmable logic controllers being connected to a second bus system of a second type, as a result of which the programmable logic controllers can be controlled and/or monitored by the user computers via one of the gateway computers, wherein to set up a communication link between one of the user computers and one or more of the programmable logic controllers, the user computer contacts a virtual gateway computer having a virtual identifier for all gateway computers of the automation system, which virtual gateway computer establishes a physical communication link to a selected one of the gateway computers.
