ON THE CREATION OF A RATIONAL FOUR-LINK CRANK ROLLING MECHANISM OF A MOLD
Abstract
Planar articulated mechanisms are most widely used in modern industry, including metallurgy. Up to now, the concept of redundancy of links itself has not been formulated clearly and is often incorrect. The research has been carried out in the scientific school of Siberian State Industrial University: the redundant links in the mechanical systems arise in kinematic pairs as a result of the inevitable forced assembly of the system. The number of links, the number and classes of the used kinematic pairs of this system do not correspond to the self-aligning system described by the A.P. Malyshev. It is shown that by ensuring the movement of the links in parallel planes or with a minimum deviation from parallelism, it is possible to reduce significantly the forces arising in the kinematic pairs. In the metallurgical industry, such mechanisms operate under conditions of high temperatures and loads, which often lead to an increase in the deformation of parts, and often to jamming at their joints. The creation of mechanisms capable of adapting to changing loads will solve the problem of not only increasing the efficiency of the mechanism, but also improving the entire technological cycle performed.
