GOST 2.770-68 * UDC 62:006.354 Group T52 Interstate standard Unified system for design documentation Graphical symbols SCHEMES IN ELEMENTS OF KINEMATICS Unified system for design documentation. Graphic designations in diagrams. Cinematic elements approved by the Committee of standards, measures and measuring instruments under the Council of Ministers of the USSR in December 1967 deadline for implementing the set with 01.01.1971 Instead of GOST 3462-61 * edition (October 2000) with Amendment number 1, approved in December 1981 (MIS 2-82) 1. This standard establishes a conditional graphical notation elements of machines and mechanisms, as well as the nature and direction of motion in the circuit shown in orthogonal projections performed in all industries. Legend of general application in accordance with GOST 2.721-74. The standard is fully consistent CT SEV 2519-80. 2. Legend of machine elements and mechanisms are presented in Table. 1. 1, 2.
