Book Chapter
Gears and Vibrations in a Gearbox
Available to PurchaseSeries: ASM Technical Books
Publisher: ASM International
Published: 31 March 2024
DOI: 10.31399/asm.tb.gvar.t59360001
EISBN: 978-1-62708-435-2
Abstract
In the case of gearboxes, vibration is the primary mode of failure even at the mid-range of operating speeds. Avoiding such failures requires an understanding of gearbox design, vibration theory, and material properties. This chapter details sources and types of gearbox vibrations; characteristics of gearbox vibrations; fundamentals of periodic vibrations; and vibration theory. It provides housing design for single-stage offset parallel gearboxes, high-speed gearboxes, and epicyclic gearboxes. The chapter then provides an analysis and selection of design factors for vibration reduction. It presents five types of gear tooth geometry errors. The chapter also focuses on gear quality inspection and on bearing-induced vibrations.

Vibration Measurements
Available to PurchaseSeries: ASM Technical Books
Publisher: ASM International
Published: 31 March 2024
DOI: 10.31399/asm.tb.gvar.t59360043
EISBN: 978-1-62708-435-2
Abstract
This chapter focuses on the design of measuring devices. The devices used to measure vibration typically consist of an electronic transducer with an interconnecting cable and an alternating current voltmeter. The working principle of each type of transducer is described in this chapter along with their important characteristics and common applications. The chapter provides general guidelines for the selection of a measuring device, and discusses vibration severity levels.
Book Chapter
Identification of Vibration Sources in a Gearbox
Available to PurchaseSeries: ASM Technical Books
Publisher: ASM International
Published: 31 March 2024
DOI: 10.31399/asm.tb.gvar.t59360051
EISBN: 978-1-62708-435-2
Abstract
The cyclic nature of gearbox vibration lends itself well to the analysis in the frequency domain where the effects of a gear mesh, bearing defects, and other sources of vibration are effectively set apart, making it much easier to identify and correct the underlying causes of vibration. This chapter presents spectral maps that show how gearbox vibrations change with the rotational speed of components. It then explains how to identify the sources of vibration in a high-speed gearbox. The chapter also discusses other errors including backlash, ghost frequencies, unbalance, misalignment, mechanical looseness, and index variation form errors. It also presents the calculation of gear frequencies on gearbox vibration spectra and the influence of operating conditions.
Book Chapter
Vibration Limits for Gearboxes
Available to PurchaseSeries: ASM Technical Books
Publisher: ASM International
Published: 31 March 2024
DOI: 10.31399/asm.tb.gvar.t59360083
EISBN: 978-1-62708-435-2
Abstract
This chapter details the vibration limits for gearboxes. It focuses on critical speed and peak load. The chapter presents vibration measurement and analysis, which provides a quick and relatively inexpensive way to detect and identify mechanical problems before they become more serious and costly.
Book Chapter
Nonsynchronous and Spiking Vibrations
Available to PurchaseSeries: ASM Technical Books
Publisher: ASM International
Published: 31 March 2024
DOI: 10.31399/asm.tb.gvar.t59360091
EISBN: 978-1-62708-435-2
Abstract
Gearbox vibrations are classified as synchronous or nonsynchronous depending on whether or not they are related to the rotational speed of an internal or connected component. This chapter presents a turbogenerator case study that demonstrates the source of nonsynchronous vibration. It then provides a detailed discussion on spiking vibrations and presents design improvement and reduction of spiking vibrations.
Book Chapter
Gearbox Failures—Case Studies
Available to PurchaseSeries: ASM Technical Books
Publisher: ASM International
Published: 31 March 2024
DOI: 10.31399/asm.tb.gvar.t59360107
EISBN: 978-1-62708-435-2
Abstract
This chapter analyzes four gearbox failures, in each case identifying the underlying failure mechanism and recommending changes to reduce vibration. These include failure of an offset parallel gearbox due to gear tooth geometry error; high vibration on high-speed offset parallel gearbox; failure of an epicyclic gearbox; and vibration due to tooth wear.

Design Guidelines for Reduced Vibration
Available to PurchaseSeries: ASM Technical Books
Publisher: ASM International
Published: 31 March 2024
DOI: 10.31399/asm.tb.gvar.t59360121
EISBN: 978-1-62708-435-2
Abstract
This chapter presents guidelines for reducing gearbox vibration, with an emphasis on design factors that play major roles in influencing vibration.
Book Chapter
Development of an Epicyclic Gearbox for Reduced Vibration
Available to PurchaseSeries: ASM Technical Books
Publisher: ASM International
Published: 31 March 2024
DOI: 10.31399/asm.tb.gvar.t59360127
EISBN: 978-1-62708-435-2
Abstract
Gearbox vibrations can often be dealt with in the field by modifying, replacing, and repositioning components and adjusting operating conditions and control parameters. Every gearbox design, however, eventually reaches a point where problems due to vibration are not so easily addressed. This chapter discusses such a case, that of an epicyclic reducer plagued by subsynchronous vibration, and explains how the gearbox was redesigned, improving lifetime as well as efficiency.
