Gear Tooth Failure Modes
Extracted from ANSI/AGMA 1010-E95, this page contains a table constructed by Horsburgh
& Scott for identifying potential gear tooth failure modes. This tool is helpful
for vibration analysts, thermographers, and professionals implementing or managing
an RCM-based system.
Maintenance and Reliability Standards
SAE JA1011 Evaluation Criteria for RCM Processes
Published by SAE for organizations implementing a reliability centered management
system. This standard provides the minimum requirements for an effective reliability
process. The standard is risk-based and offers a framework for conducting risk assessments
and managing risks related to overall reliability.
SAE JA1012 A Guide to the Reliability-Centered Maintenance (RCM)
Standard
Published by SAE for organizations seeking clarification and additional guidance
beyond the criteria specified in the SAE JA1011 standard. This standard provides
additional guidelines (not requirements) beyond the SAE JA1011 standard.
Vibration Analysis Standards
ISO 17539:2003
Condition monitoring and diagnostics of machines, general guidelines. This standard
presents generally accepted guidelines to be used when establishing a condition
monitoring program. Useful as a general checklist to ensure no major elements are
missed.
ISO 10816 Series
This suite of standards provides general conditions and procedures for measuring
and evaluating vibration on non-rotating parts (bearing housings) for general and
specific types of equipment. Though a useful guideline, these standards do not account
for real-world variation that makes one level of vibration on a machine acceptable
in one case and unacceptable in others. However, these standards are useful additions
to any vibration analyst’s library as a general reference.
- ISO 10816-1:1995
Evaluation of machine vibration by measurements on non-rotating parts, part 1: general
guidelines
- ISO 10816-2:2001
Part 2: land-based steam turbines and generators in excess of 50 MW with normal
operating speeds of 1500 r/min, 1800 r/min, 3000 r/min and 3600 r/min
- ISO 10816-3:2009
Part 3: industrial machines with nominal power above 15 kW and nominal speeds between
120 r/min and 15 000 r/min when measured in situ
- ISO 10816-4:1998
Part 4: gas turbine driven sets excluding aircraft derivatives
- ISO 10816-5:2000
Part 5: machine sets in hydraulic power generating and pumping plants
- ISO 10816-6:1995
Part 6, reciprocating machines with power ratings above 100 kW
- ISO 10816-7:2009
Part 7, rotodynamic pumps for industrial applications, including measurements on
rotating shafts
ISO 18431 Series
Useful suite of signal processing standards for computerized vibration analysis
(CVA) organizations to ensure their methods conform to generally agreed standards.
But, as with all accepted standards, this standard lags recent advancements in technology.
Also, certain assumptions regarding vibration thresholds are impractical in real-world
applications and users should consider the standards more as guidelines than requirements.
ISO 21289:2008
Mechanical vibration and shock, parameters to be specified for the acquisition of
vibration data. This standard serves as a reasonable checklist for reliability professionals
to use when designing program startup procedures and the overall vibration analysis
program. Specific applications will require further interpretation for useful application.
ISO 13372 Series
Useful suite of guidelines for vibration analysis professionals, but as with all
accepted standards, lags recent advancements in technology.
- ISO 13372-1:2002
Condition monitoring and diagnostics of machines, vibration condition monitoring,
part 1: general procedures
- ISO 13373-2:2005
Part 2: processing, analysis and presentation of vibration data
ISO 18436-2:2003
Condition monitoring and diagnostics of machines, requirements for training and
certification of personnel, part 2: vibration condition monitoring and diagnostics.
This standard specifies the requirements for persons performing vibration analysis
and is used as the basis for certifying individuals. Analysts pursuing professional
certification will find this standard useful.
ISO 19499:2007
Mechanical vibration, balancing, guidance on the use and application of balancing
standards. Nearly all reliability professionals must concern themselves routinely
with balancing equipment either using internal or external resources. Regardless
of who balances, this standard is a useful source for identifying the particular
balancing standard that is best suited for a particular application.
Motor Testing Standards
IEEE 95-20002
Recommended Practice for Insulation Testing of AC Electric Machinery (2300 V and
Above) with High Direct Voltage. Part of the generally accepted gold standard for
conducting motor testing.
IEEE
43-2000
Recommended Practice for Testing Insulation Resistance of Rotating Machinery. Part
of the the generally accepted gold standard for conducting motor testing.
Safety
MSHA Homepage
The Mine Safety and Health Administration homepage is a useful resource for safety
managers. Due to the inherent and industry specific risks related to the mining
and cement industries, specialized laws, regulations, implementation and enforcement
processes are necessary. Persons and organizations working in the mining and cement
industries must be MSHA compliant.
OSHA Homepage
Due to the nature of most work associated with PdM technologies and services, maintenance
and reliability professionals must ensure an understanding of and adherence to OSHA
requirements. Additionally and just as important, this site offer resources for
improving safety programs and information on changes to safety laws and regulations.
Thermography Standards
ASTM E1934-99A(2005)
Standard Guide for Examining Electrical and Mechanical Equipment with Infrared Thermography.
Useful for IR thermography service providers and in-house thermography programs
as a guideline for planning and conducting studies. As a guideline, this standard
does not account for all best practices but may still benefit some professionals.
ISO 18434-1:2008
Condition monitoring and diagnostics of machines, Thermography, Part 1: General
procedures. This standard provides and introduction and general procedures for applying
infrared thermography testing. A broad range of machinery types (e.g. electro-mechanical,
heat exchangers) are considered. A useful tool for professionals to ensure basic
standards are used, but it does not directly address the issue that some coniditon
monitoring objectives are better fulfilled using alternative PdM technologies.
