MULTISPINDLE GEAR SHAPER Russian patent published in 1994 - IPC

FIELD: machine tool manufacture. SUBSTANCE: machine has a bed with a table carrying a machinable wheel. The table is connected to a ram by a kinematic rolling chain with end links in the form of worm pairs, which worm pairs are mounted on rams on condition of positioning their axles on concentric circles. The axles are spaced apart from the plane of symmetry of the table by a value less than the interaxial distance of the machine engagement. The rams are reciprocally moved by a drive which has a crank-and-slider mechanism with a telescopic crank and gear-ram transmissions interconnected by a distributing shaft brought into the rolling chain. The rams are positioned for radial displacement. The machine has a stabilizer for gear cutter positioning relative to the machinable teeth. EFFECT: improved structure. 2 cl, 3 dwg
