Diseño y construcción de un banco de asentamiento en frío para motores de combustión interna de cilindraje de 1200 cm3 hasta 2400 cm3

Abstract

The objective of the project is to design and build a bench for internal combustion engines with a displacement of 1200 to 2400 cc, which have gone through a grinding process, where when reassembled the internal mechanical parts come to have clearances or imperfections that can affect the combustion process and thus avoid short-term failures and unnecessary expenses which may be caused by the affected mechanical parts. For the construction of the settling bench, the structural calculation for the frame is carried out, focusing on points of interest which are required with high stress concentrators, in addition to this, the necessary calculation is carried out for the transmission of power through belt-pulley, the which will be responsible for giving rotary movement to the internal combustion engine through an electric motor. The cost analysis is carried out taking into account results such as labor, materials and design costs, which are divided by direct costs and indirect costs. Taking into account that the innovative project is a type of machinery that is not found in Ecuador, the product is valued at $520 US dollars, making it possible to use it for mechanical workshops that assemble a rectified engine, helping to reduce expenses, corrective maintenance for mechanical failures.
