Abstract

The invention discloses a torsional vibration damper for a shafting system. The damper mainly comprises a driving end, a driven end and an elastic mechanism, wherein the driving end comprises a shell I, a shell II, a drive block and a stop pin; a driven disc which is connected with a driven system through an internal spline is named the driven end; the driving end is supported at the driven end through a sliding bearing; the driving end can be rotated relative to the driven end; the elastic mechanism is connected between the driving end and the driven end; and a buffering vibration reduction element in the elastic mechanism is not the conventional single-stranded spiral spring, but consists of a multistrand spring unit. In the invention, the multistrand spring unit is used as the buffering vibration reduction element of the torsional vibration damper for the shafting system, so that the rigidity jump phenomenon existing in the torsional vibration damper which is widely applied at present is eliminated, and the torsional vibration damper has a better buffering vibration reduction effect; in addition, the novel torsional vibration damper has the characteristics of simple structure, long service life, high transmission efficiency and capability of transmitting high torque, so that the damper can be widely used in the shafting system.

Description

technical field [0001] The invention relates to a shafting torsional vibration damper, which is installed between the power drive system and the driven system in the shafting transmission system, and is used for more thoroughly attenuating the excessive torsional vibration and impact amplitude in the shafting , and suppress the resonance amplitude of the shafting resonance area and transmit large torque. Background technique [0002] The elastic mechanism of the shafting torsional vibration damper involved in the present invention is relatively similar to the elastic mechanism of the dual mass flywheel (Dual Mass Flywheel-Circum ferential Short Spring, DMF-CSS), that is, a combination spring is used to realize The function of the long arc spring has good nonlinear characteristics and can realize the classification of the elastic characteristics of the shock absorber. The buffer and vibration damping element in the DMF-CSS elastic mechanism is a single-strand coil spring (sin...
