Lesson 13. limits, fits and tolerance. 1.1 limits fits and tolerance. two extreme permissible sizes of a part between which the actual size is contained are called limits. the relationship existing between two parts which are to be assembled with respect to the difference on their sizes before assembly is called a fit.

Evaluate limits and fits for an assembly pair 6 h7 g6 mm solution: the size 6 mm lies in the diameter step of 3 6. the fundamental tolerance unit is = 0.7327 μm tolerance for hole h7 tolerance = 16i = 12 μm the fundamental deviation h hole = zero tolerance for g6 shaft tolerance = 10i = 8 μm. Evaluate limits and fits for a pair of –diameter 6 h7 g6 solution: the size 6 mm lies in the diametral step of 3 6, therefore, d is given by – the value of fundamental tolerance unit is given by – limits of tolerance for hole h7 the standard tolerance is –16 i = 16x0.7327 = 11.72 = 12 µm the fundamental deviation h hole is –0. Which limits are fixed actual size – measured size . 2,3 limits – maximum and minimum permissible sizes. 4,5 deviation – max. and min. difference from a nominal size (1 2 or 1 3) 6 tolerance – total allowable variance in dimensions (upper limit – lower limit . or . 2 3 or 4 5).
