The design of any mechanism begins with the design of its scheme. Subsequent calculations for strength, structural design of links and kinematic pairs, choice of materials, and other stages of the design, as a rule cannot significantly change the basic properties of the mechanism. The design of mechanisms scheme on the specified properties is called synthesis of mechanism. In this work we considered the software package of kinematic synthesis of spatial gear lever mechanisms for five, seven, eight and nine parameters.
