AI Technical Summary

Technical Problem

In torsional vibration damper, the vibration damping spring wears during operation due to contact with the outer edge of the window, resulting in poor vibration damping effect and broken parts, and excessive offset causes more serious wear.

Method used

Adopting an eccentric design and auxiliary limit protection main structure, by setting the second auxiliary limit protection main body and the first auxiliary limit protection main body, the arc-shaped extrusion limit convex plate and sliding adjustment card plate are used to limit the deviation of the vibration-absorbing spring. Move the range to reduce contact time and friction with the outer edge of the window.

Benefits of technology

It extends the service life of the vibration damper parts, reduces the contact time between the vibration damper spring and the outer edge of the window, prevents large deviation and shaking, effectively slows down the wear of the window and spring, and maintains the vibration damping effect.

Abstract

The invention relates to the technical field of torsion dampers, in particular to an eccentric torsion damper spring window anti-abrasion structure which comprises a first driven disc, a damping spring, a damping disc, a driving connecting shaft, a second driven disc, a first auxiliary limiting protection body, a second auxiliary limiting protection body, a damping disc window, a driven disc window and a first limiting pin column. The first driven disc and the second driven disc are arranged on the two sides of the vibration reduction disc, and the second auxiliary limiting protection body and the first auxiliary limiting protection body are arranged on the first driven disc and the second driven disc correspondingly. Due to the eccentric effect, the outer edges of the windows of the driving disc and the driven disc are not consistent with the outer edge of the window of the vibration reduction disc, under the limitation of the windows of the driven disc and the driving disc, the vibration reduction spring and the outer edge of the window of the vibration reduction disc can leave the vibration reduction disc when the relative displacement occurs, and compared with a concentric design, the vibration reduction effect is better. And the contact time of the damping spring and the window of the damping disc is reduced, so that the service life of parts is prolonged.
