Definitions
- the invention relates to a conveyor unit according to the preamble of claim 1.
- WO 92/15 785 A1 describes a delivery unit for delivering liquids known in which the pump unit is an internal gear pump.
- This internal gear pump also known as a gerotor
- the bearing journal and with it the inner pinion is driven by a motor.
- Between the pinion and the race is an outer pinion, which is from the inner pinion is also rotated.
- the internal sprocket is equipped with one tooth less than the outer pinion, so that a pumping effect occurs. All parts of the internal gear pump, such as the race, inner pinion and outer pinion are made of metal.
- a conveyor assembly is shown in EP 0 464 261 A1, in particular for conveying of fuel, with an electric drive motor and a coupled one Pump unit (gerotor), which is a base plate, an intermediate plate with a Recess for the circumferential pump parts and a cover includes.
- gerotor which is a base plate, an intermediate plate with a Recess for the circumferential pump parts and a cover includes.
- the base plate and the lid are made of a ceramic material, wherein the end faces of the base plate facing the intermediate plate and of the lid have ground surfaces.
- the invention has for its object a conveyor unit according to the preamble of claim 1 to be quieter and corrosion-resistant. Further the conveyor unit should have a lower weight.
- this object is achieved in that all parts of the internal gear pump, d. H. Race, inner pinion and outer pinion from a ceramic Material exist, the surface of the tooth contours of the internal pinion and of the outer pinion after its production from the natural sintered skin of the ceramic Material is built up.
- a method for producing a conveyor assembly according to the invention for Pumping liquids is characterized in that for the production of all Parts of the internal gear pump, d. H. Race, inner sprocket and outer sprocket, a ceramic Material is used, and the surface of the tooth contours of the Inner pinion and the outer pinion is constructed so that these after manufacture have a natural sinter skin and thus a uniform surface structure.
- the surfaces of the tooth contours advantageously become running properties of the inner pinion and the outer pinion by typical contour-shaping processes, such as B. finished pressing or injection molding, so that advantages the natural sintered skin can be fully used with ceramic materials, like the even surface structure. A grinding process would run and Significantly deteriorate noise properties.
- the ceramic material is aluminum oxide or silicon carbide. Of course, all alloys are also included here.
