Diseño y construcción de un brazo oleo hidráulico para montaje y desmontaje de motores hasta una tonelada.

Abstract

An oil-based hydraulic arm was designed and built to assembly and disassembly engines up to one ton, in order to facilitate the repair process of gas and diesel engines, allowing easy and safely handling. Each of the structural elements was calculated according to the kind of steel, based on the DAS standard (design allowable stress). The structural design was carried out with the help of magazines provided by the manufacturer and calculations applied to the design of structures, this enabled to size each mechanical element which support the maximum load for this design. To determine in what position work the structure will subject was considered: direction of the applied force, material strength and safety factor. With these parameters and taking into account three working positions and four different loads, the maximum position was determined to pick up the load. The choosing of electrical items and hydraulic oil was achieved by the values obtained in the structural design, and rely on correctly use of magazines provided for these systems. In the structural elements was obtained in a safety factor of 2, in the hydraulic oil system a maximum pressure of 200bar and the electric system with 220Vac voltage. With the implementation of this oil-based hydraulic arm was easily to handle a load of 1000kg, thus delivering safety and ergonomics to the operator. It is recommended not exceed the limit load for which it was designed
