Simulation of broaching operations for tool design optimization [PDF]

open access: yes, 2010
In this study, an approach for simulation of broaching operations is presented. The proposed approach calculates the cutting forces, power, maximum stress at the tooth root, chip thickness and rake angle distribution on all teeth, and the workpiece ...

Nonlinear Dynamics Analysis of the Wheel-Side Planetary Reducer with Tooth Wear for the In-Wheel Motored Electric Vehicle

open access: yesMathematics
This paper investigates the nonlinear dynamics of the wheel-side planetary reducer, considering the tooth wear effect. The tooth wear model based on the Archard adhesion wear theory is established, and the impact of tooth wear on meshing stiffness and ...

The optimal design of standard gearsets [PDF]

open access: yes, 1983
A design procedure for sizing standard involute spur gearsets is presented. The procedure is applied to find the optimal design for two examples - an external gear mesh with a ratio of 5:1 and an internal gear mesh with a ratio of 5:1.

A new species of Dipoides from the Pliocene of eastern Oregon [PDF]

open access: yes, 1934
Numerous remains of castoroid rodents from the Tertiary of North America have been referred to the Old World genus Dipoides Jaeger. Apparently, most of the material represents types generically distinct from Dipoides, and the genus is actually ...
