VIBRATORY WAVE-TYPE MOTOR Russian patent published in 1995 - IPC

FIELD: transportation means. SUBSTANCE: vibrators are installed in housing. Opposite ends of flexible members of driving link arranged in one plane are coupled with vibrators. Driven link made in form of toothed wheel is installed between flexible members for engagement with the latter over working surface. Members are tubular, and toothed wheel has even number of teeth. Envelope of tooth spaces and tips of teeth is concave in cross section. To increase duration of continuous operation by intensification of link cooling, vibrators are made hollow, forming, together with flexible members, a closed circulation circuit filled with cooling liquid. This provides intensive convention transfer of heat, relieved as a result of elastic energy dissipation, to liquid. EFFECT: enhanced performance characteristics owing to prevention of displacement of driven link. 2 cl, 2 dwg
