  • Bearing Load Calculation

    For spiral bevel gears, the direction of the load varies depending on the direction of the helix angle, the direction of rotation, and which side is the driving side or the driven side. The directions for the separating force (K s) and axial load (K a) shown in Fig. 4.5 are positive directions. The direction of rotation and the helix angle

    tion." The "action" is the force, or load; the "reaction" is the effect that the supports exert on the beam or frame. Since every structure is made from materials that pos-sess elastic properties, the structure will undergo defor-mations due to the loads imposed upon it. In the case of the simple beam with a single concentrated load

    The intended load for a load cell is always aligned in the direction of the center of the earth, in other words in the direction of gravity. Only that force component of the load should be acquired. That is not the case for force sensors, which are similar in design, and are also frequently specified as "load cells": They are usually designed
