Orbital Forming of Automotive Wheel Bearings

Orbitform-Jake Sponsler
  • Technical Paper
  • 2019-01-2133
To be published on 2019-09-15 by SAE International in United States
Orbital forming is considered an optimal assembly process for many designs of automotive wheel bearing assemblies. More specifically, this process involves forming the spindle over the inner race of the wheel bearing to retain the inner ring and to maintain bearing preload. The unique forming properties and precise controls allow orbital forming to produce an ideal finished retention feature and form for these types of bearings. This paper discusses the specific benefits of orbital forming of automotive wheel bearings. Forming basics, the physics behind the benefits of orbital forming, as well as pre-form lip geometry and other part design considerations are presented. Advanced machine control methodologies and historical machine process improvements are also reviewed concluding with next steps in process control and in-machine quality assurance.

Waymo, GM and Ford pegged as autonomous leaders

According to a new report from Navigant research, Waymo (Google), GM and Ford have earned the title of “leaders” in regards to their progress in developing autonomous-vehicle (AV) platforms. The report seeks to assess the status of the leading manufacturers, suppliers, and tech companies regarding readiness to develop and launch SAE Level 3-5 systems in the next decade. The criteria by which manufacturers were compared include vision, go-to-market strategy, partners, production plans, technology and staying power.

Oxygen Cylinder Installation Guide

A-10 Aircraft Oxygen Equipment Committee
  • Aerospace Standard
  • ARP5021B
  • Current
Published 2019-04-11 by SAE International in United States
This document provides guidance for oxygen cylinder installation on commerical aircraft based on airworthiness requirements, and methods practiced within aerospace industry. It covers considerations for oxygen systems from beginning of project phase up to production, maintenance, and servicing. The document is related to requirements of DOT-approved oxygen cylinders, as well to those designed and manufactured to standards of ISO 11119. However, its basic rules may also be applicable to new development pertaining to use of such equipment in an oxygen environment. For information regarding oxygen cylinders itself, also refer to AIR825/12.
