In addition, irregular run-out is the result of worn or rough bearings which can manifest itself as either axial or radial run-out. Run-out will be present in any rotating system and, depending on the system, the different forms may either combine increasing total runout, or cancel reducing total runout.
total indicator reading; total indicated run-out: For measurements of eccentricity and other deviations from nominal geometry TOS: top of steel: TOL: tolerance, tolerancing: TSC: theoretical sharp corner(s) See discussion at SC and POI. TY: type: For an explanation of "type" abbreviated as "TY", see the example given at "CL" meaning "class ...
In metrology and the fields that it serves (such as manufacturing, machining, and engineering), total indicator reading (TIR), also known by the newer name full indicator movement (FIM), is the difference between the maximum and minimum measurements, that is, readings of an indicator, on the planar, cylindrical, or contoured surface of a part ...
The specification containing this symbol is considered as a location tolerance when the specified datum is locking rotational and translation degrees of freedom. The toleranced feature is a surface. Run-out: ↗ : circular run-out: The nominal toleranced feature is a set of circles. ⌰ total run-out: The nominal toleranced feature is a plane ...
ASME Y14.5 is a complete definition of Geometric Dimensioning and Tolerancing. It contains 15 sections which cover symbols and datums as well as tolerances of form, orientation, position, profile and runout. [3] It is complemented by ASME Y14.5.1 - Mathematical Definition of Dimensioning and Tolerancing Principles.
A runout may include any of the following: Runout (climbing), a section of a rock climbing route with a long gap between points of protection; Run-out, an inaccuracy of rotating mechanical systems, specifically when a tool or shaft does not rotate exactly in line with the main axis. Run out, a method of dismissal in the sport of cricket.
The radial run-out can be expressed as the peak-to-peak value as well as harmonic values. Radial run-out imparts an excitation into the vehicle in a manner similar to radial force variation. It is most often measured near the tire's centerline, although some tire makers have adopted measurement of radial run-out at three positions: left ...
