Title: Innovations of Jeffrey Brengle Finn

Introduction

Jeffrey Brengle Finn is an accomplished inventor based in Cedar Falls, IA (US). He has made significant contributions to the field of gear technology, holding a total of 2 patents. His work focuses on improving the durability and efficiency of gear systems, which are essential components in various mechanical applications.

Latest Patents

Finn's latest patents include a process for durability improvement of gear tooth flank surfaces and an axle assembly featuring dual planetary reduction. The first patent details a method where pinion gears for planetary gear transmissions are hobbed, heat treated, and ground to enhance control over the leads and profiles of all gear teeth. A light shot peening is then applied to achieve the desired compressive residual stresses on the tooth surface. This controlled process prevents over-cold working of the surface. Additionally, a chemically assisted isotropic surface treatment is applied to improve the surface finish of the gear teeth, which is particularly beneficial for low-speed applications by enhancing the lambda ratio and ensuring a good oil film thickness.

The second patent describes an axle assembly for motor vehicles that includes a pair of axle half-shafts designed to transfer rotational motion to spaced apart wheels. A differential is positioned between the axle half-shafts, with a dual planetary gear set interconnecting each half-shaft to the differential. This innovative design features two planetary gear sets mounted back to back, sharing a ring gear, which optimizes the performance of the axle assembly.
