Abstract
A cylindrical gear train comprising first and second gears having helical eth of different thickness with different pitch diameters for the left hand and right hand sides of the teeth and with different nominal angles of inclination and different mesh correction for the mating left hand and right hand flanks of the teeth. Within the normal module range of m.sub.n =2-6 mm, corresponding to the normal module range of 2.pi.(mm) to 6.pi.(mm), and for pitch diameters up to 500 mm, the maximum tooth convergency is 3.degree. and the addendum modification coefficient does not exceed 0.8.
Claims3
A gear train comprising first and second cylindrical gears having helical teeth, each tooth having left hand and right hand sides with respective different pitch diameters, the teeth of the first and second gears having different nominal angles of inclination and different mesh correction for the left hand and right hand mating flanks of conjugate teeth whereby within the normal module range of 2 to 6 mm, corresponding to the normal pitch range of 2.pi.(mm) to 6.pi.(mm), and pitch diameters up to 500 mm, tooth convergencies up to 3.degree. are provided, the addendum modification coefficient value not exceeding 0.8.
