Components of a machine and their functions

The general components of a machine they are the power source, the motor, the mechanism, the frame, the regulation and control system and the safety components.

They are the basic and standardized mechanical parts, which are used as building blocks in most machines, which usually have common sizes and are manufactured in series.

The machines are made up of three types of elements: the structural components, the movement control mechanisms and the control components themselves..

Although shape, color and texture are not considered elements of a machine, however, they are an important part of it, because it offers a practical and design interface.

What is a machine?

It is a set of assembled fixed and mobile elements that allow transforming, regulating, directing or simply taking advantage of energy. The machines perform tasks and functions autonomously or automatically when manipulated by an operator.

A machine is made up of a series of simple and common components or elements for almost all of them, and that are essential for them to function and fulfill the tasks for which they were created by man..

General components of a machine

A machine is made up of the following basic elements:

Power source

It is the form of basic energy or fuel that allows the machine to operate. It can be electricity, oil, gasoline, alcohol, etc..

Motor

It is the mechanism that performs a certain job by transforming the energy source that feeds it or serves as combustion.

The motors themselves are transforming machines of other types of energy (kinetic, chemical, electrical) into mechanical energy. This is possible by rotating on an axis or moving a piston alternately.

Motors that transform mechanical energy into kinetic energy are called transformers. Compressors and pumps also fall into this category.

Mechanism or transmission

This other component comprises a series of mechanical elements that when grouped together form a system, whose function is to transform the energy provided by the motor into the final movement or action sought with the machine..

This function is fulfilled by transmitting the power between one or more elements of the machine. The mechanism transforms the speed, the force, the trajectory and the energy in other different types of each one of them.

According to the number of elements, the mechanisms can be classified into:

- Simple: those with 2 link elements.

- Complexes: if they have more than 2 link elements

Frame

It comprises a rigid structure that supports the motor and the mechanism. Its function is to guarantee the connection or coupling of all the elements of the machine.

Various aspects must be taken into account when designing the rack for safety reasons..

First, each of the machine's components, then the stress and deformation analysis to, from there, design the best possible structure according to the design needs..

Regulation and control system

They are the control components used to regulate the operation and force of the machine, coupling it to the required work..

These are the switches, buttons, indicators, sensors, actuators, and controllers.

Safety components

They are essential to ensure the safe operation of the machine. Although they do not help the work that it performs and they serve to protect the operators.

These components are part of the mandatory industrial and occupational safety today. Its periodic maintenance is essential to guarantee its proper functioning.
