Hydraulic control rotating shaft power self-adaptive shock absorber and shock absorption method

Abstract

The invention discloses a hydraulic control rotating shaft power self-adaptive shock absorber and a shock absorption method. The shock absorber comprises a plurality of shock absorption modules of the same structure, each shock absorption module comprises an arc-shaped rail base, a sliding block and a connecting rod, the rail bases are connected with the sliding blocks through rail mechanisms, the sliding blocks can rotate around the rotating center axes of the sliding blocks, arc-shaped channels are symmetrically formed in the sliding blocks, and push rods are installed in the two arc-shaped channels correspondingly. Springs are arranged between the push rods and mounting bases on the same side, cylinder barrels are mounted on the sliding blocks, piston rods are mounted on the cylinder barrels in a matched mode, a closed area formed by the left push rod, the right push rod, the sliding blocks, the cylinder barrels and the piston rods is a hydraulic control area, and supports are fixedly mounted on the sliding blocks on the two sides of each cylinder barrel separately. Kidney-shaped holes are formed in one ends of the connecting rods, the connected rods are hinged to the piston rods through the kidney-shaped holes, centrifugal blocks are arranged at the other ends of the connecting rods, and the middle of the connecting rods is hinged to the supports. The hydraulic control rotating shaft power self-adaptive shock absorber is convenient to install, and the optimal vibration and noise reduction effect can be automatically obtained according to the rotating speed change of a rotating shaft.

Description

technical field [0001] The invention relates to a shock absorber and a vibration reduction method, in particular to a shock absorber and a vibration reduction method for vibration reduction of a rotating shaft. Background technique [0002] The gear shaft transmission system is widely used in various transmission systems, but due to various factors, including machining accuracy, eccentric force and external meshing excitation, etc., the transmission system has certain vibration and noise. Civilian equipment has serious implications. [0003] In order to reduce the vibration and noise level of the transmission system of the equipment as much as possible, at present, the method of increasing damping is mainly used to achieve vibration reduction and noise reduction. This type of vibration reduction method is passive vibration reduction, and the effect is not obvious. In order to be able to deal with the vibration caused by the operating frequency of the transmission system at ...

[0002] The gear shaft transmission system is widely used in various transmission systems, but due to various factors, including machining accuracy, eccentric force and external meshing excitation, etc., the transmission system has certain vibration and noise. Civilian equipment has a serious impact

[0003] In order to reduce the vibration and noise level of the transmission system of the equipment as much as possible, at present, the method of increasing damping is mainly used to achieve vibration reduction and noise reduction. This type of vibration reduction method belongs to passive vibration reduction, and the effect is not obvious.
