Variabilidade e Previsão Climática de Vazões na Margem Esquerda da Bacia do Alto Paraná (Brasil)

An apparatus for mounting a bearing onto a shaft is disclosed. The apparatus includes a base plate and a support mounted to and extending upward from the base plate. The support is capable of supporting a shaft. The shaft has a shoulder, a tapered surface adjacent to the shoulder and a threaded portion adjacent to the tapered surface. A shim is positioned on the shaft adjacent to the shoulder and a bearing is positioned adjacent to the shim. The bearing has an inner race, an outer race and a plurality of roller elements positioned there between. The bearing is mounted onto the shaft by a lock nut which is secured to the threaded portion of the shaft and which contacts the inner race of the bearing. The apparatus further includes a motor mounted to the base plate. The motor has an output shaft which is axially aligned with and connectable to the outer race of the bearing. The motor is capable of rotating the outer race of the bearing at a predetermined speed. A force sensor is attached to the motor which is capable of measuring the amount of torque required to rotate the outer race at a predetermined speed. The measured torque is then visually displayed on a display unit. When the measured torque is within the predetermined torque range, the bearing will be mounted.
