BED TESTING GIMBAL GEARS Russian patent published in 1999 - IPC

FIELD: evaluation and test of gimbal gears. SUBSTANCE: given bed includes frame, electric motor kinematically coupled to one of shafts of tested gimbal gear, loader placed in series in power circuit, technological cardan joint with hollow cross-piece, members to link tested gimbal gear. In this case one fork of technological cardan joint is made fast via linking members to one of external forks of tested gimbal gear and the other fork of technological cardan joint is hollow and is coupled via loader and linking members to the other external fork of tested gimbal gear. EFFECT: reduced consumption of energy used for testing, decreased usage of materials in structure, enhanced reliability of bed equipment and authenticity of test results. 1 dwg
