FIELD: instrument engineering. ^ SUBSTANCE: invention concerns rotation to reciprocation or contrariwise transforming tools. A geared linkage transformer comprises a frame, a shaft that bears a drive gear with external teeth, a wheel with external teeth with eccentric axis, a kinematic chain providing constant axle spacing of the gear and the wheel, a drive link, as well as a driven link that is supported by the eccentric axis of a gear wheel directly or via intermediates. The guide link is connected to the wheel axis with a hinge and to the frame with either a sliding pair, or a hinge. Along with the tooth wheel rims, the gear and the wheel accommodate bearing raceways. The kinematic chain represents a closed rolling element system that involves a female ring and auxiliary rolling elements spaced between the gear and the ring. Auxiliary rolling elements can be smooth or toothed. In order to balance the inertia running torques, the transformer can consist of two opposite-phased converters within one common drive shaft. ^ EFFECT: decision aims at higher rotation frequency of a crankshaft with invariable design dimensions, ensured arrangement of a number of driven links within the same plane. ^ 4 cl, 4 dwg |
