- 1Clarence fita loose fit between the parts that that there is always space between them
- 2transitional fitbetween a clearance fit and an interference fit
- 3interference fitparts must be forced together with a press because there is no space between them
- 4spur gearflat, tooth gear
- 5piniondrive gear
- 6gear rationumber of teeth on one care as compared to its mating gear
- 7diameter pitchnumber of keys on one gear as compared to its mating gear
- 8pressure anglethe angle at which tears make contact-either 14,5° for older designs or 20° for modern design
- 9pitch diameterimaginary circle with a diameter at the midpoint of the gear tooth height
- 10faced widththe thickness of the care choose also contact service for transferring power
- 11helical gearflat, tooth gear with teeth cut at an angle for running quietly with high torque
- 12bevel gearhere with teeth cut so that it can work with another care mounted at an angle to it
- 13worm hereshaped like a screw thread used for low-speed and high torque's
- 14GD&Tgeometric dimensioning and tolerances; geometric standards that define mechanical parts
- 15formtolerance that include the geometric form (cylindricity, flat, and so on) of apart
- 16true positionideal location of a feature
- 17profile of a linevariation of a line is ideal location and shape
- 18profile of the surfacevariation of a 3D surface from its ideal location in shape
- 19run outhow much an object "wobbles" when rotated about is axis
- 20datum planeplane where measurements are reference typically (primary, secondary, and care tertiary), and 90°
- 21feature control frameblock on a drawing that outlines features tolerance and specifications
- 22parallelismdescribe how to parallel surface have been manufactured
- 23perpendicularitydescribe how to perpendicular surface have been manufactured
- 24angularitydescribe how closely to surface match a given angle
- 25concentricitya measure on how closely the axis of chew circular features match
- 26RFSregardless of feature size, means that tolerances must be independent of feature sizes
- 27projected tolerance zoneextending the geometric tolerance to a height above the surface to account for bolts and fasteners
