WAVE DRIVE AND METHOD OF ITS ASSEMBLY (VERSIONS) Russian patent published in 2001 - IPC

FIELD: machine elements. SUBSTANCE: wave drive housing with cover; electric motor is mounted inside housing on flange having "n" radial projections (n= 3, 4, etc); wave drive is also provided with wave transmission; each of "n" closed slots of fixed flexible wheel is used for receiving the radial projection of flange. Overall dimension of flange is lesser than inner diameter of flexible wheel in one of positions relative to flexible wheel. During assembly, flange is turned to position when it is inscribed by inner diameter of flexible wheel and is forced inside flexible wheel, after which it is turned (at even number of projections on flange) relative to its longitudinal axis till two opposite projections are received by opposite slots of flexible wheel or is shifted (at odd number of projections) radially till one of projections of flange is received by one of slots of flexible wheel and then it is turned relative to axis of projections received by slots till remaining projections are received by remaining slots; then flexible wheel together with flange inside it, as well as electric motor, wave generator and rigid wheel are mounted. EFFECT: increased loading capacity of wave drive. 4 cl, 9 dwg
