Abstract

According to calculation method of tooth gears wear and durability it has been conducted an investigation of influ-ence of double – single – double - tooth engagement on maximal contact pressures, teeth wear and gear durability at constant contact conditions in correlated helical gearing. It is suggested the method of defining the angles of transition from double to single-tooth engagement and vice versa. It has been established that correlation decreases maximal contact pressures on 14…20% depending on the type of correlation. Permissible wear is faster reached by gear wheel teeth. Depending on the shift coefficient values and engagement correlation type maximal wear would be reached in different typical points of con-tact: at the entrance into double-tooth engagement, at the entrance into single-tooth engagement or at the exit of it. It has been established that gear durability has its optimum at certain shift coefficients. The obtained results are presented graphically what allows tracing the regularities of influence of engagement conditions
