Tuned mass damper for cantilever-type hollow thin-wall rotor

Abstract

The invention relates to a tuned mass damper for a cantilever-type hollow thin-wall rotor. The tuned mass damper for the cantilever-type hollow thin-wall rotor comprises a main body mechanism and a supporting mechanism, wherein the main body mechanism comprises an auxiliary mass block, a connecting rod and two spherical bearing blocks; the supporting mechanism comprises two end closures, a hollowcylinder, a positioning sleeve and a ball bearing; the auxiliary mass block and the connecting rod are jointing components; the auxiliary mass block is positioned in the middle of the connecting rod;a spherical bearing block is arranged at two ends of the connecting rod respectively; two spherical bearing blocks are embedded into the respective end closures which are opposite to each other; the two end closures seal the main body mechanism into the hollow cylinder; the hollow cylinder is tightly sleeved by the positioning sleeve; the ball bearing is arranged on the outer side of the center of the hollow cylinder; and the hollow cylinder is supported on the inner side of the thin-wall rotor through the ball bearing. The tuned mass damper for the cantilever-type hollow thin-wall rotor can reduce the vibration response of a tubular cylinder of a winding machine in the running process and ensure the production quality of chemical fibrous filaments.

Description

technical field [0001] The invention relates to the field of shock absorbers, in particular to a tuned mass shock absorber for a cantilevered hollow thin-walled rotor. Background technique [0002] In industrial production, cantilevered thin-walled rotors have already appeared, such as the key equipment for the production of chemical fiber filaments - high-speed winding machine, which itself is a time-varying, multi-interface coupled, high-speed rotor system, its main components The bobbin chuck is a typical cantilevered hollow thin-walled rotor. [0003] When the winding machine is working, multiple threads are wound onto the bobbin chuck at a constant linear speed. The vibration response of the bobbin not only directly affects the production quality of chemical fiber filaments, but also pollutes the environment and affects The accuracy of other equipment and the physical and mental health of operators. In 2009, the Ministry of Industry and Information Technology clearly ...
