Abstract

Abstract: The pressure fluctuation is the key technical indicator to evaluate the accuracy class of bell provers. The design of cam linetype for buoyancy compensation is researched deeply. Concrete method of involute linetype design of cam is advanced. Meanwhile, differences between involute and Archimedes spiral in applicaion to bell prover are analyzed. The crucial design question of bell prover is solved and further research on bell prover of higher accuracy class is guaranteed.

Key words: Bell Prover, Buoyancy Compensation, Cam, Involute
