For more than a century this company has worked to build a solid reputation based on innovation, excellent customer service, and a commitment to quality.

Although Oliver Gear is celebrating its 100th anniversary this year—it was incorporated in 1907 as a gear-manufacturing company—it’s actually much older, having been founded as a machine shop by A.F. Oliver in 1892. Would he recognize the company today? “I think he’d be surprised by how much we’ve grown,” according to Michael Barron, vice president […]

Turbo – Abrasive Machining for Edge and Surface Finishing

In addition to mechanical deburring, turbo-abrasive machining provides benefits including isotropic surfaces, improved profiles, and beneficial compressive stress.

Turbo-Abrasive Machining [TAM] is a mechanical deburring and finishing method originally developed to automate edge finishing procedures on complex rotationally oriented and symmetrical aerospace engine components. Since its inception this method of utilizing fluidized abrasive materials has facilitated significant reductions in the amount of manual intervention required to deburr large components. Additionally, the process has […]

Bending Fatigue of Surface Densified Gears

A technical paper discussing the effect of root densification depth and tooth loading mode on fatigue life.

Surface densified powder metal gears and conventional wrought steel gears were tested using a pulsator and a back-to-back gear tester to develop bending fatigue data. Two types of powder metal spur gears (wheel and pinion) were manufactured by pressing and sintering followed by surface densification using the DensiForm® process. Reference wrought steel (AISI 8620) gears […]

Electrical erosion is a factor to take into account when conducting a failure analysis

When conducting a failure analysis, electrical erosion is yet another factor to take into account. This installment provides helpful insights into this phenomena.

With the rapid advance in gear technology, new hitherto unforeseen failures can occur, and typical among them are failures due to electrical discharge. Such failures are scantily dealt with in most literature, if at all. Even current technical association documents tend to gloss over the phenomena. Electric motor and bearing manufacturers are aware that, although […]
