Gear transmission system

摘要

A gear transmission system (20) comprising at least a first cylindrical gear (21) and a second cylindrical gear (22). Each of the first and the second cylindrical gears (21, 22) comprise a plurality of teeth (23, 26). The teeth (23) of the first cylindrical gear (21) having a first tooth flank (24) for contacting a first tooth flank (27) of the teeth (26) of the second cylindrical gear (22) according to a predefined first contact line (30). The first tooth flanks (24, 27) of the teeth (23, 26) of each of the first and second cylindrical gears (21, 22) have a tooth shape and tooth properties determined by the predefined first contact line (30).

1. A gear transmission system (20) comprising:
at least a first cylindrical gear (21) having an axial width in an axial direction and a second cylindrical gear (22) having an axial width in the axial direction, each of the cylindrical gears (21, 22) comprising a plurality of teeth (23, 26), the plurality of teeth of the first and the second cylindrical gears each have a first tooth flank (24, 27) and a second tooth flank (25, 28), and in a transverse plane at a first axial position in the axial direction, the first tooth flanks of the teeth (23) of the first cylindrical gear (21) contact the first tooth flanks (27) of the teeth (26) of the second cylindrical gear (22) according to a predefined first contact line (30), wherein the first tooth flank (24, 27) of each of the plurality of teeth (23, 26) of each of the first and the second cylindrical gears (21, 22) have a first flank shape and first flank properties being determined by the predefined first contact line (30), the second tooth flank (25, 28) of each of the plurality of teeth (23, 26) of each of the first and the second cylindrical gears (21, 22) having a second flank shape and second flank properties being determined by a predefined second contact line (30), the predefined first contact line (30) being different from at least the second predefined contact, and at least one of the first flank shape and the first flank properties varies in the axial direction along the axial width of the first flank.
