The contact condition and performance of a crossed helical gearpair of line contact for a spinning machine are researched. In this pair, the driving gear is a plastic helical gear with the working flank profile transferred from the counterpart, the driven gear is a steel involute helical gear, and the shaft angle is 90°. A method for computing the gap between two working flanks in a plane perpendicular to the axis is given, and the contact lines on both working flanks are obtained numerically. Their shapes differ considerably in terms of the helix angle, and some of them are illustrated. The working flank of a plastic gear is produced by cutting the flank of a plastic involute helical gear with a specially designed gear hob having an involute tooth fiank. The improvements in the noise level, power transmission efficiency and wear compared with the case of point contact are confirmed experimentally.
