Variable-Structure Impact Mechanism with Dynamic Coupling

Variable-Structure Impact Mechanism with Dynamic Coupling

Developer: Laboratory of Stone Mining Complexes

Purpose and scope:

The impact mechanism is designed for impulse destruction and processing of solid materials, including natural stones. The field of application is mining, mining and processing, construction industries, road construction and repair works.

Brief description of development

The proposed mechanical shock device with a dynamic coupling on the principle of operation can be attributed to hammer types of mechanisms in which blows are applied to the material with hammers hinged on a rotor rotating at high speed, in which the force of impact is determined by the speed and mass of the hammer. The presence of hinged and free-rotating links excludes reactive forces at the time of impact by the waveguide on the material. The increase in the durability of the mechanical impact mechanism is due to the opening of the mechanism-tool-material chain at the time of energy transfer, which eliminates the destructive effect of the reaction on the bearings and supports of the mechanism. In addition, the design of such a mechanism is simple, small, low installed power of the electric motor and economical in manufacture.

Level of development

According to the results of the study and refinement of the experimental sample, the design of the impact mechanism of the variable structure with a dynamic bond was refined. Extensive testing is planned in production conditions.

Commercial offers

It is proposed to conclude contracts for the manufacture and supply of products, as well as conduct further research and development to obtain modern competitive products.
