COMPARATIVE ANALYSIS OF INVOLUTE AND SINUSOIDAL GEAR TRANSMISSIONS IN MACHINE DRIVES UNDER CONTACT AND FRICTION CONDITIONS
The study results of the conditions of contact and friction in two types of gear engagements - involute and sinusoidal - are presented. The main advantages and disadvantages of traditional involute gears are analyzed, and the advantages of sinusoidal gears in some operational parameters of machine drives are noted. It is shown that the sliding speed of the profiles and the amount of contact friction are significantly lower in the sinusoidal mashing.
