In this experiment a small plastic ball is attached at one end of a light aluminum rod while the other end is tied to a circular disk. Two such rods and balls are available, see Fig. 1. The disk is mounted on a metallic shaft attached to a stepper motor's coupler. When the stepper motor starts rotating, the disk also rotates and plastic balls ...Web

Abstract. To meet the high requirement on cutter stiffness in five-axis machining of complex parts with deep channels, such as an aero-engine blisk, conical ball-end cutter is preferred over the traditional cylindrical cutter as the former can increase the stiffness ten folds or more over the latter of a same size.Web

Like a ball bearing, a roller bearing has two grooved tracks, or races, but the balls are replaced by rollers. The rollers may be cylinders or truncated cones. Only radial loads ( i.e., loads perpendicular to the axis of rotation) can be carried when the rollers are cylindrical, but with conical rollers both radial and thrust, or axial, loads ...Web

STEP 8. Sealing, mounting and dismounting. For bearings with a tapered bore, inner rings are always mounted with an interference fit. The degree of interference is determined by how far the bearing is driven up onto a tapered shaft seat or an adapter or withdrawal sleeve. As the bearing is driven up the tapered seat, its radial internal ...Web

The conical-cylindrical shell is prone to stress concentration in the convex cone position under the action of deep-sea pressures. This results in unidirectional or bidirectional positive tensile stresses on the surfaces of the shell. The conical-cylindrical shell is a large, welded structure. Welding residual stress was generated at the cone …Web
