... in the weight range of 2268 to 4536 kg (5000 to 10,000 lb) are products made by a forging process creating a pair of flanges and a pinion shaft diameter at one time. The inboard and outboard flanges along with the pinion diameter become integral parts of the main shaft diameter. The forging operation...

... Abstract The design requirements for mechanical shafts, pinions, and gears often call for features with very hard surfaces (to resist wear) based on a softer core (to avoid brittle fracture). This chapter explains how to selectively harden steel by diffusing carbon and nitrogen atoms...

... motion into reciprocating linear motion. The eccentric shaft is connected through a clutch and brake system directly to the flywheel ( Fig. 11.8 ). In designs for larger capacities, the flywheel is located on the pinion shaft, which drives the eccentric shaft ( Fig. 11.9 ). The constant clutch torque, M...

... Another common design problem is parts with holes, deep keyways, and grooves. One illustration of this problem is hardening of a shaft with a lubrication cross hole, as illustrated in Fig. 20 ( Ref 19 ). Preferred alternative designs are also shown in Fig. 20 . If a radial cross hole is mandatory...

... In an aircraft engine, the gear system failed after 40 hours of run. The driven gear had fractured, and a portion of it had fallen off. The remaining teeth of this gear, the teeth of the driving bevel gear, and the pinion of the shaft had been damaged. The primary cause for the fracture of the driven gear...

... with this configuration are gear teeth and various types of antifriction bearings. However, the same type of failure can occur where a convex shape fits within a concave shape, such as a shaft within a sliding bearing or balls in a ball-bearing race. These situations are shown in Fig. 1 . In these configurations...
