<p>Melt pumps for pressing synthetic melt through a tool are disclosed. An example melt pump for building up pressure for pressing synthetic melt through a tool includes a compressor with two worm conveyors disposed in a housing, a transmission by means of which the worm conveyors are synchronously drivable, and a drive, where the transmission is disposed between the drive and the compressor. In the example melt pump, each worm conveyor in the transmission has an output shaft, and each worm conveyor is coupled to the corresponding output shaft by a coupling. In the example melt pump, the coupling comprises an output gear provided on the output shaft, and a drive gear provided on the worm conveyor and a coupling sleeve gripping the output gear and the drive gear, where the drive gear and the output gear have a different number of teeth.</p> |
