INTRODUCTION

ASSEMBLY

The purpose of this project was to examine the driver gearbox of a B&D Li2000 screwdriver and use computer-aided design (CAD), specifically Creo 5.0, to model its parts and create appropriate engineering drawings. This project also demonstrated how to deconstruct and reassemble the device, analyze the multi-stage epicyclic gear train of the gearbox in terms of its gear ratio and pitch diameters, and recognize specific features that function either as mistake-proofs or practical mechanisms.

To view the details of these components, please explore the rest of this website using the gearbox tab at the the top or the page arrows by the heading.

The image below displays the product structure of this screwdriver with emphasis on the gearbox. Note that the handle and battery pack was not disassembled.
