Abstract

This study aims to analyze the heat transfer fin efficiency and a speed reducer Crown / Endless. The material is aluminum reducer and the reduction is 15:1. We used a ½ HP motor and gearbox coupled to tests conducted with and without load. The experiments were performed on a test bench electromagnetic brake (brake Foucault) in natural convection. To perform the temperature measurements, we used the device HBM QUANTUM MX-840A and a contact thermocouple type K. The calculation of the convection coefficient was performed by experimental and theoretical mathematical model, and the experimental method prevailed at work, because the theoretical method has some restrictions. The fin efficiency was calculated by one-dimensional. For a more efficient heat transfer, it was proposed to change the geometry of the flap and conducted tests on forced convection, thus, there was obtained a reduction of the surface temperature. The values of fin efficiency obtained were all close due to small temperature ranges that occurred in the experiment. For all testing a thermal imager was used to obtain thermal images and comparing the results.
