In India, “namaste” is used as a common greeting. Although it translates
literally to “I bow to you,” it’s often
used the same way we use “hello” or
“good-bye.” It’s a phrase commonly
exchanged between individuals when they meet, and it’s also used as a salutation when they part. I’m using the
phrase here because I’d like to introduce you to an exciting new project
and venture for Randall Publications LLC.
There are a number of companies
working to change the way broaching is perceived, and over the past 10 years, they’ve incorporated significant
technological changes to make the process more flexible, productive
Super-reduction hypoid gears (SRH) are
bevel worm gears with certain differences regarding hypoid gears. If two axes are positioned in space and the task is to transmit motion and torque between them using some kind of gears with a ratio above 5 and even
higher than 50, the following cases are commonly known. Tribology Aspects in Angular Transmission Systems, Part VIII.
This article provides an overview of the benefits of using psychoacoustic characteristics for describing gear
noise. And with that, human hearing and the most important psychoacoustic values are introduced. Finally, results
of noise tests with different gear sets aree presented. The tests are the basis for a correlation analysis between psychoacoustic values and gear characteristics.
In this article, the authors calculated the numerical coordinates on the tooth surfaces of spiral bevel gears and then modeled the tooth profiles using a 3-D CAD system. They then manufactured the
large-sized spiral bevel gears based on a CAM process using multi-axis control and multi-tasking machine tooling. The
real tooth surfaces were measured using a coordinate measuring machine and the tooth flank form errors were detected
using the measured coordinates. Moreover, the gears were meshed with each other and the tooth contact patterns were investigated. As a result, the validity of this manufacturing method was confirmed.
Metalworking technology specialists will be front and center for six days at EMO Hannover 2011 (September 19–24). More than 2,000 companies from 38 countries will be on-hand to show off products and services, spotlighting
their performance capabilities.
