MOTION CONVERTER WITH DEVICE FOR INCREASING ITS LOAD-CARRYING CAPACITY Russian patent published in 2003 - IPC

FIELD: mechanical engineering; engines. SUBSTANCE: invention relates to devices converting rotation into reciprocation. Each device is provided with movable geared frame made in form of two toothed racks mating at end faces with support semicyclinders, and gear with incomplete number of teeth installed on shaft for alternate engagement with toothed racks. Gear is installed for implementing function of lever rolling between axis of shaft rotation and line of gear contact with surface of support semicylinders of geared frame by surface of gear free from teeth. To increase load-carrying capacity, end face surfaces of longitudinal stops installed lengthwise the racks are made coinciding with side profile of end face teeth of toothed racks for complete or partial taking of working load by end face surface of longitudinal stop together with side surface of first tooth. Moreover, pitch of teeth of toothed rack taken as sum of base of tooth profile and base of tooth space is made with beginning from base of tooth space, starting from section of butt of toothed rack and mated support semicylinder. EFFECT: reduced inertia loads, overall dimensions and masses, increased load-carrying capacity. 3 cl, 4 dwg
