STUDY ON WELDED STRUCTURE GEARS (4TH REPORT, EFFECTS OF WEB ARRANGEMENTS ON GEAR VIBRATIONS)

In this paper the authors investigated the effects of web arrangements on vibration of welded structure gears. The circumferential, radial and axial vibration accelerations of various types of welded gears were measured under different running conditions. The vibration accelerations of welded gears increase generally with an increase in the rigidity of web and rim parts of the gears. A double web gear shows the largest values of vibration accelerations and an asymmetric type of a welded gear the smallest ones due to the effects of the axial force, which is produced by a deformation of the rim and the web parts of the welded gear. The conversion rate of the circumferential vibration into a radial or axial one is different according to the type of the web arrangement.
