Vibration damping device of gear transmission flywheel

Abstract

The invention discloses a vibration damping device of a gear transmission flywheel, which comprises a box body, a rack and a first transmission shaft, wherein the rack is erected at the two ends of the box body; the first transmission shaft is arranged in the box body through a bearing; and one end of the first transmission shaft is provided with a first gear engaged with the rack, and the other end of the first transmission shaft is provided with the flywheel. In the device, the rack and the first transmission shaft are erected on the box body; and one end of the first transmission shaft is provided with the first gear engaged with the rack, and the other end of the first transmission shaft is provided with the flywheel. Through rack-gear transmission, the vibration of reciprocating linear motion is converted into the rotational motion of the flywheel, so that the inertia property of a large mass block can be acquired by the flywheel with lower mass in the device; and when the rack moves in the reverse direction, the reverse motion of the flywheel can be prevented due to the higher inertia property of the flywheel. The aim of vibration reduction can be fulfilled in combination with the frictional damping effect of the transmission of the gear. In the device, a damper and the large mass block are not required and the cost is correspondingly reduced.

Description

technical field [0001] The invention relates to the technical field of vibration damping devices, in particular to a gear transmission flywheel vibration damping device. Background technique [0002] In a mechanical system, in order to obtain the expected vibration reduction effect, springs, dampers, mass blocks, etc. are often added to the mechanical system to form a vibration isolation system to change the vibration characteristics of the mechanical system. In order to reduce the transmission rate of the main system at the excitation frequency, the vibration isolation system usually reduces the high-frequency vibration transmission, that is, an additional mass block with a larger mass is installed on the mechanical system to increase its mass, so as to achieve a lower natural vibration of the system. frequency purpose. [0003] The additional mass block must have a larger mass to achieve the above technical effect. However, on the one hand, a large mass mass block puts fo...
