UNIVERSAL SET OF GAUGE RODS Russian patent published in 2014 - IPC G01B5/02 

FIELD: measurement equipment.

SUBSTANCE: invention relates to the field of mechanical means of measurement, namely, to accessories for measurement of certain parameters of parts (length, width, thickness, etc.), specifically - to sets of gauge rods, and may be used in different areas of machine building, for instance, in production of tools, in assembling for measurement of gaps, in tuning of pointer-type measuring instruments, etc. In the universal set of gauge rods, comprising five groups of elements, dimensions of all elements of the set are subject to dependences (1) $$A_{1-m}=A_{n-\left(m-1\right)}+{\delta }_{\left(m-1\right)}иA_{nm-m}=A_{1-m}+\left(n_m-1\right){\delta }_m,\left(1\right)$$ , where A_1-m is size of the first element of the group with the number "m"; A_n-(m-1) and δ_(m-1) is size of the last element and pitch of sizes of the group with the number "m-1"; A_nm-m, n_m and δ_m - size of the last element, the number of elements and pitch of sizes of the group with the number "m". Number of elements in groups is subject to dependence (2) $$n_1=\left(K_1{\delta }_1-A_{11}\right)/{\delta }_1+1иn_m=\left[K_m{\delta }_m-\left(K_{(m-1)}+1\right){\delta }_{\left(m-1\right)}\right]/{\delta }_m+\mathrm{1,}\left(2\right)$$ , where n₁ and n_m - number of elements of the first group and group with the number "m", accordingly; K₁, K_(m-1) and K_m - ratio of the value of the size of the last element of the group to the value of the pitch of sizes of this group for the first group, groups with the number "m-1" and with the number "m", accordingly; A₁₁ - size of the first element of the first group of the set; δ₁, δ_(m-1) and δ_m - pitch of sizes of the elements of the first group, groups with the number "m-1" and with the number "m", accordingly, and values of ratios K₁…K_m are in intervals of integer natural numbers 100≤K₁≤201, 51≤K₂≤150, 8≤K₃≤20, 5≤K₄≤50, 1≤K₅≤10), are subject to dependence (3) $$K_m=A_{nm-m}/{\delta }_m\left(3\right)$$ and meet the condition (4) $$\begin{array}{l}{K}_1\left[1-{\delta }_1/{\delta }_2\right]+\dots +K_{\left(m-1\right)}\left[1-{\delta }_{\left(m-1\right)}/{\delta }_m\right]+K_m=\\ =\left(N-5\right)+A_{11}/{\delta }_1+\left[{\delta }_1/{\delta }_2+\dots +{\delta }_{\left(m-1\right)}/{\delta }_m\right],\left(4\right)\end{array}$$ where N is the total number of elements in the set, N=n₁+n₂+n₃+n₄+n₅.

EFFECT: improved manufacturability of sets, convenience (efficiency) in operation.
