DEVICE FOR CHANGING THE SPEED OF A STRESSED WAVE GEAR WITH A LARGE GEAR RATIO

摘要

FIELD: machine engineering.;SUBSTANCE: device for changing the speed of a stressed wave gear has rings and an element of a wave generator. The element of the wave generator is connected to one of the input and output shafts of the device. There are four rings, two of them are coaxial pairs of round rings (number of teeth A and D) and curved rings (number of teeth B and C). Large rings are engaged with each other, small rings are engaged with each other. Two rings of one of these two coaxial pairs are fastened together to act epicyclicly on the wave generator. One ring of the other of the two coaxial pairs is attached to the frame of the device, the other ring is connected to the other of the input and output shafts. The ratio of teeth A=K+i, B=K, C=K-j, and D=K+i-j-j or K+i-j.;EFFECT: increasing the gear ratio.;13 cl, 14 dwg, 2 tbl
