Problems solved by technology

This unbalanced centrifugal force acting on the rotor bearing will cause vibration, generate noise and accelerate bearing wear, which will seriously affect the performance and life of the product. At the same time, the gyroscopic effect generated by the rotation will cause the movement and deflection of the mechanism

Abstract

The invention discloses a tune damper with opposing torque action. The tune damper comprises a planet gear mechanism and a rubber vibration isolator (2), wherein the rubber vibration isolator (2) is uniformly fixed on the wheel flange of the planet gear mechanism; the planet gear mechanism and the rubber vibration isolator form a combining tune damping vibration-reducing structure; the planet gear mechanism comprises an annular gear (1), a sun wheel (3), a planet gear (4), a planetary gear carrier (5), a first end cover(6), and a second end cover (7), wherein the planet gear (4) is arranged on the periphery of the sun wheel (3) and connected with the sun wheel (3), the rubber vibration isolator (2) is connected with the wheel flange of the planet gear (4), the planetary gear carrier (5) is used for placing the planet gear (4), the first end cover (6) is connected with the rubber vibration isolator (2), and the edge of the second end cover (7) is connected with the edge of the first end cover (6); and the wheel flange of the annular gear (1) is fixed on the first end cover (6).The tune damper provided by the invention has the advantages of reducing torsion of a rotating mechanism and bending vibration.

Description

technical field [0001] The invention relates to a vibration damping method combined with a tuning damper with reverse moment effect, a planetary gear mechanism and a rubber vibration isolation pad, which is suitable for dynamic moment balance of a rotating mechanism and can reduce torsional and bending vibrations of the rotating mechanism. Background technique [0002] Any rotating mechanism, when rotating about its axis, generates centrifugal force due to the uneven distribution of mass with respect to the axis. This unbalanced centrifugal force acting on the rotor bearing will cause vibration, generate noise and accelerate bearing wear, which will seriously affect the performance and life of the product. At the same time, the gyroscopic effect generated by the rotation will cause the movement and deflection of the mechanism. [0003] The tuned damper has the characteristics of simple design method, various forms, and strong pertinence. The common feature of these devices i...
