STIFF STRUCTURE OF ECCENTRIC CON-ROD AND GENERATOR OF VIBRATIONS Russian patent published in 2015 - IPC B06B1/00 

FIELD: transport.

SUBSTANCE: this invention relates to stiff structure of eccentric con-rod and generator of vibrations. Claimed invention comprises stiff structure of eccentric con-rod and generator of vibrations including said stiff structure of eccentric con-rod. Note here that said stiff structure of eccentric con-rod comprises rotary drive (20) with drive shaft (21). Eccentric con-rod (30A, 30B) is shaped to, in fact, a bar with offset weighed section (33) on the side of first end (31) and con-rod section (34) engaged with said drive shaft (21) on the side of second end (32). Said con-rod is revolved by force transferred from rotary drive (20) via drive shaft (21). Oscillating section (40) has bearing section (44) inside the section located nearby said first end (41) so that said first end (31) of con-rod (30A, 30B) is fitted in said bearing section (44). Note here that said offset weighed section (33) has first central axis (33t) extending in lengthwise direction of said offset weighed section (33). Note here that said section (34) has second central axis (34t) extending in lengthwise direction of said section (34). Here, extension line (34s) is defined by extension of said second central axis (34t) in direction of said offset weighed section (33). Angle (θ) between said first central axis (33t) of offset weighed section (33) and said extension line (34s) is larger than 0° and not over approximately 10° at the state whereat said first end (31) of con-rod (30A, 30B) is not fitted in said bearing section (44) so that con-rod (30A, 30B) is locked so that said first end (31) of con-rod (30A, 30B) regularly pushes inner peripheral of said bearing section (44).

EFFECT: decreased noise at low and high rpm.
