Análisis y Propuesta de Mejora de un Sistema de Precarga Para los Rodamientos de los Reductores Delanteros en los Tractores CASE PUMA

Abstract

There are various types and brands on the market. tractors, these are used in different companies of the agricultural sector; their functions vary according to their size and class, as well as brands. The CASE PUMA tractors are used within the process productive of the company, such as: lifting and harvesting the cane, the preparation of the land, among others. The following project shows the analysis and proposal to improve a preloading system for the bearings of the front reducers of the CASE PUMA tractors, in order to provide a new design that allows increasing the useful life of the machine, in turn reducing the costs of maintenance and repair. For this, an analysis was carried out on the mechanism of preload system, where the factors that affect the work of the machine, since in turn influences its useful life. Finally, with the aforementioned analysis Previously it is possible to identify the root of the problem and the possible solution, which consisted of redesign of the tightening nut, considering for this a new way of fitting and material selection. He redesign allowed to improve work times and tractor maintenance, reducing costs and increasing its use time.
