Abstract

The invention relates to a torsion chaos vibration exciter, and belongs to the technical field of mechanical transmission equipment. The torsion chaos vibration exciter comprises n movable components, m rotation pairs are formed through the n movable components, and the torsion chaos vibration exciter with the freedom degree being F is formed. The torsion chaos vibration exciter is used in mechanical transmission equipment, the wider torsion vibration frequency namely the chaos characteristic and shaper angular speed changes are achieved in the torsion (rotation) movement direction, in other words, the requirements of the industries are better met, and the work efficiency and the machining quality can be improved; and wide application prospects are achieved in the industries of machine manufacturing, agricultural machines, light industry, petroleum, chemical engineering, food, civil engineering, mining and metallurgy and the like.

Description

technical field [0001] The invention relates to a torsional chaotic vibration exciter, which belongs to the technical field of mechanical transmission equipment. Background technique [0002] At present, the usual mechanical transmission equipment is a single-degree-of-freedom transmission in the direction of rotation, without the excitation torque of chaos and drastic angular velocity changes, while the existing chaotic vibrator is used to generate chaos and drastic velocity changes in the linear direction The exciting force does not have chaos in the direction of torsion (rotation) and more severe angular velocity changes. However, with the development of modern mechanical transmission equipment technology, higher requirements are put forward for certain industries, such as pressure processing, crushing, screening, drilling, cutting, vibration aging, blanking and other mechanical equipment. The existing single-degree-of-freedom mechanical transmission equipment and the ch...
