Abstract

JSC "Kharkiv Machine-Building Plant "Svitlo Shahtarja" has created and introduced into serial production a new generation UKD200-500 coal shearer. The most loaded element of the shearer is its cutting part. It is a three-stage reducer with an electric motor. Calculations for the strength and durability of gearing, shafts, bearings, spline, pinned and hinge joints have been carried out. The modeling of the stress-strain state for the main parts and assemblies by the finite element method has also been carried out. Calculations have shown that the strength and durability of all parts is ensured. Consequently, the required durability of 15000 hours and the average resource before major overhaul are not less than 800...1000 thousand tons are provided.
