Variable damper

Abstract

The invention discloses a variable damper which comprises a baseboard, an isolation spring, a damping cylinder, a damper regulator, damping medium, a piston, a sealing ring and a top board; the isolation spring is fixedly arranged between the baseboard and the top board; the damping cylinder is arranged on the baseboard and filled with damping medium; the piston is arranged in the damping cylinder; the sealing ring is arranged at the opening of the damping cylinder and seals the gap between the piston and the damping cylinder; the extending end of the piston is fixedly connected with the top board; the lateral side of the damping cylinder is provided with a pipeline; and the damper regulator is arranged at the middle of the pipeline. The damping effect of the inventive variable damper is variable and can be meticulously and continuously regulated, thus satisfying requirements of various occasions with frequent vibration working condition variation.

Description

technical field [0001] The invention relates to the technical field of vibration reduction and isolation of mechanical vibration, in particular to a variable damping shock absorber. Background technique [0002] The existing shock absorbers and vibration isolators have a constant damping effect under the condition of a certain damping medium, but the frequency of the vibration source is often changed, for example, the frequency is different when the machine starts, runs, and stops. When the damping effect is constant, a good vibration reduction effect cannot be achieved. If you want to change the damping effect, you must change the characteristic temperature and viscosity of the damping medium, that is, you must replace the damping medium. Therefore, the existing various shock absorbers and vibration isolators cannot meet the occasions where the vibration conditions change frequently. Contents of the invention [0003] In order to overcome the deficiencies in the prior ar...

[0002] The existing shock absorbers and vibration isolators have a constant damping effect under the condition of a certain damping medium, but the frequency of the vibration source is often changed, for example, the frequency is different when the machine starts, runs, and stops. When the damping effect is constant, the good vibration reduction effect cannot be achieved.

If you want to change the damping effect, you must change the characteristic temperature and viscosity of the damping medium, that is, you must replace the damping medium. Therefore, the existing various shock absorbers and vibration isolators cannot meet the occasions where the vibration conditions change frequently.
