What is helical gearing?
Helical gears are suitable for conveying highly viscous media. With helical gearing, the teeth no longer run in a straight line in alignment, but at an oblique angle to it. Helical gearing is particularly suitable for transmitting high torques. Especially in the polymer sector, where highly viscous melts have to be conveyed at high pressures, helical gearing is the first choice.
Due to the wandering engagement point from one side to the other, which is created by the rotation of the shafts, this type of gearing has low pulsation. Especially in (highly) viscous polymer applications, this ensures very uniform polymer delivery. In addition, undesirable vibrations in pipelines of upstream and downstream aggregates, etc. can be avoided as a result.
