Abstract

The invention relates to a three-directional shafting dynamic vibration absorber and a design method thereof. The three-directional shafting dynamic vibration absorber adopts the structure as follows: mounting shaft sleeves are tightly fixed to the surface of a shafting; the outer sides of the mounting shaft sleeves and the inner sides of circular masses are connected in a vulcanizing manner through rubber components; the circular masses, the rubber components and the mounting shaft sleeves are designed into two semicircular rings respectively; clamping slots are formed in the circular masses and the mounting shaft sleeves respectively; an outer clamping hoop is clamped into the clamping slots of the two semicircular ring-shaped circular masses to abut the two semicircular ring-shaped circular masses into a circular ring; an inner clamping hoop is clamped into the clamping slots of the two semicircular ring-shaped mounting shaft sleeves to abut the two semicircular ring-shaped mounting shaft sleeves into a circular ring. The three-directional shafting dynamic vibration absorber adopts a split structure, is simple in structure and easy to mount, can achieve bending and twisting of the shafting and control of longitudinal vibration, overcomes the defects that measures needing to change the structure and the material of the shafting are complicated in implementation and relatively high in expenses, and overcomes the defects that an active vibration absorber is complicated in structure and high in producing cost and needs additional energy.

Description

technical field [0001] The invention relates to a dynamic vibration absorber and a design method for reducing vibration levels in three directions of shaft system bending, torsion and longitudinal direction, and belongs to the technical field of vibration absorption. Background technique [0002] Shafting is widely used in various rotating mechanical equipment and vehicles such as ships and automobiles. At present, the shafting of large-scale units and equipment at home and abroad generally has the problem of large vibration. There are many researchers on shafting vibration control, and their methods can be roughly divided into two categories. One is to start from the supporting structure and materials of the shafting system, that is, to select bearings of different structures and materials, and select a reasonable spacing for layout and installation, so as to reduce the vibration during the operation of the shafting system (Yao Shiwei et al., Research Progress of Rubber Bea...
