摘要
The object of the invention is a melt pump for building up pressure for pressing a melt of plastic material through a tool, comprising a compressor (406) with two worm conveyors (408, 408') disposed in a housing, a transmission (405) by way of which the worm conveyors (408, 408') are synchronously drivable and a drive (404), wherein the transmission (405) is disposed between the drive (404) and the compressor (406), wherein each worm conveyor (408, 408') in the transmission (405) is provided with its own output shaft (416, 416') and wherein the worm conveyor (408, 408') is connected to the corresponding output shaft (416, 416') by way of a coupling (414, 414'); and also a melt pump in which the worm gap between the two worm conveyors is easily adjustable due to the fact that the coupling (414, 414') comprises an output gear (418, 418') provided on the output shaft (416, 416'), a drive gear (419, 419') provided on the worm conveyor (408, 408') and a coupling sleeve (421, 421') gripping the output gear (418, 418') and the drive gear (419, 419'), wherein the drive gear (419, 419') and the output gear (418, 418') have a different number of teeth.
