Boeing End Effector Project
The Boeing Company, specifically the Maintenance and Ground Operations Systems (MGOS) group, has asked our team, Pacific Rim Engineering, to design a manipulating end effector. This end effector will be attached to a boom hoist and will aid maintenance personnel in the removal and installation of components requiring performance evaluation and/or servicing. The end effector will be sold to the various airlines that use Boeing aircraft in their fleets. The end effector needs to be user friendly and be designed to meet server specific physical constraints; it must allow the six basic degrees of freedom (translate side to side, up and down, in and out 3 inches, as well as have 30º of controlled rotation about the x, y and z axis), it must be able to lift upwards of 150 lbs (contained in a cube no larger than 18 inches), the effector must have an overall weight of less than 250 lbs. Project deadline: December 8, 2006.

Belshaw Donut Machine Gearbox and Boot Redesign
The purpose of this project was to stop the gearbox from leaking oil into the batter for the Belshaw Brothers Inc. The boots that are currently attached to each gear-box fail during operation at a very low service life. Our task was to redesign the boot and gearbox so that they will last ten times longer than the current setup. The current boot is being manufactured by Rainer Rubber and is made of silicone rubber. The design of this boot causes high stress points, which lead to cracking and failure after only two weeks of use. The gearbox is open, and can leak lubricant out into the batter, so a boot is required to prevent this leaking. Design specs were created to analyze what was needed for this project to be completed and the problems to be resolved. Our group met with Michael Wierman and directed all communication to him. This document includes all specifications for the product design. Project deadline: December 8, 2006.
