Solution aiming the technological improvement of worm and star wheel from single screw compressor

Journal Title: Proceedings in Manufacturing Systems - Year 2017, Vol 12, Issue 2

Abstract

Single screw compressors are frequently used due to their constructive simplicity, leading to a lower price. The level of functional noise is also lower than in the case of other compressors. They usually include a central worm whose profile is generated by a star wheel with rectangular transversal profile. This paper proposes a solution enabling an easier machining of the worm, with the help of an end mill cutter. A new shape of the star wheel tooth is proposed, issuing from the analysis of central worm – star wheel gear, on the base of the fundamental theorems of reciprocal enwrapped surfaces. As consequence, a new constructive solution for the star wheel, which is the element that ensures compressor’s sealing, is suggested. An analytical solution of the specific enwrapping surfaces problem is presented together with the new constructive shape of the star wheel.
