GEAR TESTING GEAR-WHEELS FOR BENDING STRENGTH AND FATIGUE OF THEIR TEETH

摘要

FIELD: testing equipment. SUBSTANCE: invention can be used for testing teeth of spur gears and helical gears for bending strength and fatigue. Gear testing gear-wheels for bending strength and fatigue of their teeth has body, loader and intermediate member to transmit load to gear wheel. Intermediate member is manufactured in the form of prismatic frame installed in symmetry with regard to vertical axis in middle face section of tested gear-wheel rests against two teeth between which there is one tooth not experiencing load. Prismatic frame is fitted with separable high-strength cylindrical rods set in special grooves of prismatic frame placed at angle of inclination of teeth on element of cylinder of gear-wheel. EFFECT: approximation of testing conditions to real ones, expanded testing capabilities. 3 cl, 4 dwg
