Definitions

  • the invention relates to a toothed belt pump, which is mainly used as a controllable metering and feed pump for non-lubricating liquids.
  • a toothed belt pump is known from US Pat. No. 2,745,355, which has a plurality of toothed disks which engage with a toothed belt. In this pump, suction and pressure chambers must be separated from each other by separate spacers.
  • DE 2 560 128 C2 also describes a pump with a conveyor belt which rotates on two pulleys. This pump has a different functional principle compared to the toothed belt pump according to US Pat. No. 2,745,355. By changing the curvature of the path of movement of the toothed belt, the working chambers located between the tooth heads change their cross section.
  • the object on which the invention is based is to develop a toothed belt pump which can be constructed in a structurally simple manner and is also suitable for higher pressures.
  • This object is solved by the features of claim 1.
  • the advantages achieved by the invention are, in particular, that inexpensive commercially available toothing parts can be used for pump production.
  • Special features are an optimal form-fitting power transmission, a large power and speed range, maintenance-free continuous operation, low-noise operation, long service life and constant angular velocity due to the circular wrapping, which is not in the form of a polygon or polygon and thus avoids vibrations and noises.
  • the toothed belt pump consists of an elongated pump housing 1, in which a drive shaft 2 is mounted centrally and receives a toothed pulley 4 via a positive connection 3.
  • the external toothing of the toothed pulley 4 engages in the toothing of a toothed belt 5.
  • the toothed belt 5 runs over deflection rollers 6 and 7, which are rotatably mounted on both sides of the toothed pulley 4 in its axial plane and parallel to one another, their distance from the toothed pulley 4 in the axial plane corresponding approximately to the thickness of the basic profile of the toothed belt 5.
  • the toothed belt 5 lies in the area of the wrapping of the deflection rollers 6 and 7 and in the region of its straight line after leaving the wrapping of the deflection roller 6 up to the point where the opposite deflection roller 7 touches the inner wall of the housing.
  • the inner wall of the housing on its opposite side from the flat region is designed to be true to the circumference of the two deflecting rollers 6 and 7 and the toothed disc 4.
