According to the author's method of calculation of metal-polymer (MP) gears, the study of contact strength and resource of MP helical spur gears with a gear made of unfilled polyamides PA6, PA66 and composites based on polyamide PA6 filled with glass (PA6 + 30GF) or carbon (PA6 + 30CF) fibers, molybdenum disulfide (PA6 + MoS2), cast with oil (PA6 + Oil). The conditions of the teeth engagement in the meshing cycle are taken into account. The calculation of the maximum contact pressures during the cycle of tooth interaction - from the entrance to the engagement to the exit from it at different helical angles. The durability of transmissions is calculated and their comparative estimation at use of the specified polymeric materials is resulted. Qualitative and quantitative regularities of change of the specified service characteristics of MP gears at achievement of the accepted admissible teeth wear of polymeric gears are established.
