PIEZOELECTRIC DRIVE OF ROTARY MOTION Russian patent published in 1994 - IPC

FIELD: domestic appliances. SUBSTANCE: piezoelectric drive of rotary motion has body housing two pushers-sliders matched to linear piezodrives made with extension piece of stroke. Overrunning clutch manufactured in the form of output bushing, intermediate rollers and sleeve-shaped casing is installed along axis of body. Face of casing has diametrical protrusions which sides interact via balls with pushers-sliders converting reciprocating motion of linear piezodrives into rotary motion of casing. To change rotational speed balls may move over diametrical protrusion of casing. Piezoelectric drive is coupled to unit of domestic appliance, for instance, screw of meat mincer, set in motion with the help of output bushing of overrunning clutch. EFFECT: simplified design, improved operational reliability. 2 dwg
