Abstract

The actual scientific problem is solved in the work, which consists in substantiation of the algorithm of modeling of the jaw crusher mechanism with a simple movement of the jaw on the basis of using SOLIDWORKS modelling tools. Empirical equations are obtained, which relate the parameters of the crusher: the height and thickness of the fixed and movable jaws and connecting rod, the length of the spacer plates from the size of the loading inlet, the size of the eccentricity from the stroke of the jaw. It is recommended to use the received regularities at designing the domestic crushers with a simple movement of the jaw.

Highlights

В роботі вирішена актуальна наукова задача, яка полягає в обґрунтуванні алгоритму моделювання механізму щокової дробарки з простим рухом щоки на основі використання інструментів моделювання SOLIDWORKS

It is marked: fixed jaw I — is modelled by a rod hinged in nodes 1 and 2; movable jaw II — is represented by a T-shaped rod (О1-3-5-6), which is hinged in node О1; front spacer plate III — is depicted in the form of a rod 6-7; rear spacer plate IV — is marked with rod 8-O3, hinged in node O3; connecting rod V —is presented in the form of a T-shaped rod (7-8-9-10); eccentric shaft VI — is modelled by a 10-O2 rod, which is hinged in O2 node

Summary

Introduction

В роботі вирішена актуальна наукова задача, яка полягає в обґрунтуванні алгоритму моделювання механізму щокової дробарки з простим рухом щоки на основі використання інструментів моделювання SOLIDWORKS. The sizes of аn outlet (the size of the crushed material), the stroke of a movable jaw, the size of eccentricity, coordinates of fixed supports, overall dimensions differ. This suggests that there is no unification despite the presence of state standard (DEST). Presenting main material Using modern SOLIDWORKS modelling tools, we will determine the relationship between the size of the eccentricity and the links of the mechanism of jaw crushers with a simple movement of the jaw and the stroke of the movable jaw. It is marked: fixed jaw I — is modelled by a rod hinged in nodes 1 and 2; movable jaw II — is represented by a T-shaped rod (О1-3-5-6), which is hinged in node О1; front spacer plate III — is depicted in the form of a rod 6-7; rear spacer plate IV — is marked with rod 8-O3, hinged in node O3; connecting rod V —is presented in the form of a T-shaped rod (7-8-9-10); eccentric shaft VI — is modelled by a 10-O2 rod, which is hinged in O2 node
