Abstract
The invention relates to a measuring device for determining the mass rate of flow of a mass flow, especially for measuring a flow of bulk material. An impeller wheel (), which is connected to the drive shaft () and which is driven at a constant rotational speed, is thus provided. The impeller wheel () deviates an axially impinged mass flow in a radial direction and provides it with a radial and tangential speed component. The drive shaft () includes a spur-toothed wheel () which engages with an intermediate spur-toothed wheel () and which is driven by a driving spur-toothed wheel (). The intermediate spur-toothed wheel () is mounted on a force transmitting arm () which is maintained in a radial position by a force measuring device. The drive shaft () is surrounded by a bearing bushing () which protrudes into the housing area () of the impeller wheel () and which is driven by a separate driving means () at a rotational speed which corresponds to the rotational speed of the drive shaft (). The bearing bushing () is rotatably mounted in a fixed part of the housing, such that basically no relative speed occurs between the drive shaft () and the bearing bushing ().
