Superfinishing Gears: The satae of the art, Part II

摘要

Chemically accelerated vibratory finishing of gears using high density, non-abrasive ceramic media has generated much interest among gear designers and users. Increasingly, this gear superfinishing technology is being used to solve real-world problems. However, implementing of this technology has been hindered by several misconceptions. In a previous Gear Technology article, the authors identified and discredited two misconceptions surrounding this gear superfinishing process. In this article, they discuss three more misconceptions. Their discussion includes evidence supporting that the performance benefits of super-finished gears are real, that the process can reduce gear noise/ vibration/harshness, and that superfinishing doesn't distort gear geometry.
