Abstract

The article deals with the process of torque camshaft at a constant speed. The method of release was determined by the normal force acting between the cam and the tappet. Subsequently, was expressed torque. A prerequisite for the calculations are a constant friction coefficient between the components of the mechanism and constant speed of the camshaft. Cam used for the purposes of this study generated polynomial lifting dependence. Part of this work is the calculation methodology lifting addiction. Course of torque is the conclusion presented on the values of the corresponding measuring station, which is the result of previous work on the subject.

Highlights

Cam mechanisms are an integral part of many machines
The cams are used as a generator of well-defined path in the so-called "hard" automation, they are part of the fitness machines, which provide the required course of torque
Stroke dependence is generated based on the desired stroke of polynomial degree and angle of connection of the cam profile on the base circle

Summary

Introduction

Cam mechanisms are an integral part of many machines. The cams are used as a generator of well-defined path in the so-called "hard" automation, they are part of the fitness machines, which provide the required course of torque. Due to the planned automation of calculation was chosen for this work approach, which was presented in 1952 Dudlym [1,2] This is the definition of lifting dependence using algebraic polynomial (1). Unknown polynomial coefficients are calculated using boundary conditions at prominent points of the cam profile For the angle of rotation φ = 0 (index 1 in Fig. 1) we introduce boundary conditions given by the relation (2). Where u is the order of the derivative that u N0 u 0; n 1 2 Of these conditions implies that the coefficients of the polynomial 0 to n 1 are equal to 0. The aim of this work is not solving the optimization equation system, but analysis of torque
