Types and Designs of Ring Gauges

Ring gauges are available in various types and designs to suit different measurement requirements. Here are some of the types and designs of ring gauges mentioned:

Standard Thread Types

Ring gauges are available for all the standard thread types, sizes, and pitches used in various industries. This includes BSPT, NPFT, NPSM, NPT, NPTF, UNC, UNEF, UNF, UNS, and Whitworth threads. The availability of ring gauges for different thread types ensures that they can be used in a wide range of applications.

Tolerance Grades

Individual ring gauges or ring gauge sets are made to a variety of tolerance grades in metric and English dimensions for master, setting, or working applications. The tolerance grade determines the allowable deviation from the nominal or desired size of the part being measured.

Higher tolerance grades indicate higher accuracy and precision.

Types of Ring Gauges

There are three main types of ring gauges: go, no go, and master or setting ring gauges. Go ring gauges provide a precision tool for production comparative gauging based on a fixed limit. No-go gauges are used to check the lower limit of the hole, and go-plug gauges are used to check the upper limit of the hole.

Master or setting ring gauges are used to calibrate other gauges or standards.

Configurations

There are several configurations of ring gauges available, which are used for checking different types of parts. Plain ring gauges feature a smooth inner diameter and are used for comparative gauging and checking of cylindrical objects.

Uses

Ring gauges are used for comparative gauging as well as for checking, calibrating, or setting of gauges or other standards. They provide a quick pass/fail assessment based on the specified dimensional tolerances or attributes of the parts.

Ring gauges are not measurement instruments in the sense that they do not provide an actual value of the part's diameter.

Considerations When Selecting a Ring Gauge

When selecting a ring gauge, there are several key features and characteristics to consider:

Material

Ring gauges are typically made of a stable material, such as tool steel, that can withstand thermal changes and maintain its shape and size over time. The material should be thermally resistant to ensure the accuracy and stability of the measurements.

Tolerance

Ring gauges are fabricated with a highly precise bore in their center that functions as the gauge for the outer diameter of the parts. The inside diameter of the ring gauge is finished to gauge tolerance, which is the allowable deviation from the nominal or desired size of the part being measured.

The tolerance should be within the acceptable range to ensure accurate and reliable measurements.

Type

There are three main types of ring gauges: go, no go, and master or setting ring gauges. The type of ring gauge needed depends on the specific application. Go ring gauges are used to check if the part falls within the upper limit of the specified range.

No-go gauges are used to check if the part falls within the lower limit of the specified range.

Master or setting ring gauges are used to calibrate other gauges or standards.

Size

Ring gauges are used to measure the outside diameter of cylindrical objects such as pins, shafts, and splines. They are made to a variety of tolerance grades in metric and English dimensions for master, setting, or working applications.

The size of the ring gauge should match the size of the part being measured to ensure accurate and reliable measurements.

Application

Ring gauges are used for comparative gauging as well as for checking, calibrating, or setting of gauges or other standards. They are used for go/no-go assessment compared to the specified dimensional tolerances or attributes of pins, shafts, or threaded studs.

The specific application should be considered when selecting a ring gauge to ensure accurate and reliable measurements.

Limitations and Challenges of Ring Gauges

While ring gauges are commonly used in dimensional measurement applications, there are some limitations and challenges associated with their use. Here are some of the limitations and challenges of using ring gauges in certain applications:

Flatness

Plain ring gauges may have flats that span a portion of the diameter being measured, which can result in an inaccurate reading of size. The presence of flats can introduce errors in the measurement process and affect the accuracy of the results.

Assumptions

Some dimensions, such as pitch diameter, cannot be taken through assumptions and must be measured specifically. Ring gauges may not be suitable for measuring certain dimensions that require more precise and specific measurements.

Wear and Tear

Limit gauges, including ring gauges, can experience errors due to wear and tear over time. The repeated use of ring gauges can lead to changes in their dimensions and affect the accuracy of the measurements.

Regular maintenance and calibration are necessary to ensure the reliability of the measurements.

Difficulty in Checking Finer Tolerances

Limit gauges, including ring gauges, may not be able to check finer tolerances accurately. The design and construction of ring gauges may limit their ability to measure very small deviations from the nominal size.

In such cases, more precise measurement instruments may be required.

Despite these limitations and challenges, ring gauges are still useful for a variety of inspection purposes. They can be used as Go/No-Go gauges to inspect the outside diameter of a shaft or rod, as masters for dial bore gages, internal micrometers, and coordinate measuring machines (CMMs), and as master gauges to set variable measuring tools.

They can also work well as a functional complement to variable gauges, as stand-alone pass/fail functional inspection tools, or as a master to set other gauges.
