Projeto de uma caixa de redução por engrenagens cilíndricas retas para um veículo Baja SAE
(2021-12-10) Andrade, Douglas Santana; Farias Filho, João Gutemberg Barbosa de; http://lattes.cnpq.br/0718103459959119; http://lattes.cnpq.br/6243297653363605
The system designed by the present work is a gearbox that uses straight cylindrical gears to reduce the rotation speed of the engine and increase the torque transmitted to the wheels. The design is made based on the maximum stresses present in the parts. These tensions will serve as a parameter to choose the materials to make the gears, shafts, keys and select the bearings. The study of the tensions present in the axes is done through the calculation of bending moment and shear force. The gears are designed according to the AGMA standard for cylindrical spur gears. The selection of the bearings is made by comparing the result of the calculation of the theoretical load on the bearing and the parts present in the catalogs. The material to be used as braces is selected by comparing the stress results with the tensile strength limit of each material. Throughout the calculation of the geometry of the parts, it is noticed that it is possible to design the box to be compact and resistant so that it has an easy installation on the vehicle.
