Title: Vijay Nagpal: Innovator in Gear Technology

Introduction

Vijay Nagpal is a notable inventor based in Westland, MI (US), recognized for his contributions to gear technology. He holds a total of 5 patents, showcasing his expertise and innovative spirit in the field.

Latest Patents

One of his latest patents is focused on cold extrusion for helical gear teeth. This process and apparatus involve machining an annular ring gear blank with precision inside and outside diameters. The gear blank is mounted on a die ring that is arranged coaxially with respect to the blank. The die ring features internal die teeth, while a mandrel with external die teeth is axially aligned with the gear blank. The mandrel or die ring is moved axially to extrude the blank through the internal and external die teeth. Another significant patent involves the extrusion forming of internal helical splines. This extrusion assembly fits into a hydraulic press and includes an upper die plate and a lower die plate mounted together by die guide posts. A lead bar is coupled to the upper die plate at one end and to a mandrel at its other end, featuring helical grooves that mate with helical protrusions on lead nuts. As the hydraulic press pushes the lead bar axially toward the gear blank, the lead nuts impart rotational motion to the lead bar, causing the mandrel to move with a helical motion as it is pressed into and pulled out of the gear blank.
