Abstract

Article is devoted to a research of the multicircuit slot mechanism for the plant of bushes vertically - the spindle harvest device of the mechanical cotton picker.

Research objective is carrying out the structural analysis of the multicircuit slot mechanism for the plant of bushes for identification of the reasons of its insufficient reliability and the development of optimum structure of the mechanism providing its sufficient reliability, durability and technological effectiveness.

The method of the structural analysis of a kinematic chain of the multicircuit slot mechanism determines quantities of the main mobile links and classes of kinematic couples, degree of freedom and the number of excess (six) communications of the mechanism. It is established that because of existence in a kinematic chain of excess communications, statically we will not define the mechanism. Taking into account possible errors of production and assembly flat multicircuit mechanisms can be considered as spatial. For definition of degree of freedom of a kinematic chain as spatial mechanism, Malyshev's formula which as the universal structural formula, allowed to estimate rationality of structure of the considered mechanism is used.

The optimum structure of a kinematic chain of the multicircuit slot mechanism where degree of freedom of the mechanism it is equal to unit W = 1 is developed, that is the mechanism is set in motion by one propeller. Assembly of such mechanism happens without deformation of links are established and quite meet requirements of reliability, durability and technological effectiveness. In the course of work mechanisms without excess communications work without scratch and noise.
