Abstract:

The article describes a device created by the author to test clock components and mechanisms for impact overloads up to 50,000 g. The impact is created by dropping a tempered steel striker with the test object on a steel surface, with the striker drop height determining the overload. The article presents a procedure for measuring magnitude of acceleration with a piezoelectric crystal pickup and describes experimental tests conducted on balance units of aircraft timepieces and K-26 timepieces, as well as Rossiya timepieces. The author suggests a design for a shockproof balance unit which uses elongated pivots. Author
