The invention discloses a worm and helical gear transmission pair based on a variable pressure angle and application of the worm and helical gear transmission pair. The worm and helical gear transmission pair is reliable in transmission, durable and easy to manufacture. In order to achieve the purposes, the worm and helical gear transmission pair based on the variable pressure angle comprises a worm and a helical gear which are engaged with each other, wherein the transverse module (Mt2) of the helical gear is equal to the shaft surface module (Ma1) of the worm; the tooth profile angle alpha n2 of the end face reference circle of the helical gear is larger than the tooth profile angle alpha n1 of the shaft surface reference circle of the worm; the swing angle beta 2 of the reference circle of the helical gear is equal to the lead angle lambda 1 of the shaft surface reference circle of the worm; the difference between the tooth profile angle alpha n2 of the end face reference circle of the helical gear and the tooth profile angle alpha n1 of the shaft surface reference circle of the worm is smaller than 10 degrees.
