UNIVERSAL KIT OF GAUGE BLOCKS Russian patent published in 2017 - IPC G01B5/02 

FIELD: measuring equipment.

SUBSTANCE: universal set of gauge blocks consists of five groups of blocks. Sizes of blocks are subject to dependences: A_1-m=A_n-(m-1)+δ_m, A_nm-m=A_1-m+(n_m-1)δ_m, where A_1-m is the size of the first block of the group with the number "m"; A_n-(m-1) is the size of the last block of the group with the number "m-1"; A_nm-m, n_m and δ_m is the size of the last block, the number of blocks and the size step of group blocks with the number "m". Step values δ₁…δ₅ of the block sizes in groups are determined by the range 1:10:20:200:2000 relative to the step size of blocks in the first group. The number of blocks in groups is subject to the dependence n_m=K_m-K_(m-1). K_m and K_(m-1) are the values of the ratio of the sizes of the last blocks in the groups with the numbers "m" and "m-1" respectively to the value of the size step in the group with the number "m". K₁…K₅ are natural integers in the intervals 100≤K₁≤150, 12≤K₂≤62, 7≤K₃≤57, 2≤K₄≤52, 1≤K₅≤10 for groups 1…5, respectively, satisfying the condition , where N=n₁+n₂+n₃+n₄+n₅.

EFFECT: increase in the effectiveness of the set by reducing the number of blocks and the weight of the set and expansion of the technological capabilities.
