Portable rotary force vibration reduction gear transmission device for high-damping shaft

Abstract

The invention discloses a portable rotary forcer vibration reduction gear transmission device for a high-damping shaft. The device comprises a vibration reduction mechanism, wherein the vibration reduction mechanism comprises a semi-vibration reduction mechanism A and a semi-vibration reduction mechanism B which are identical in structure; the semi-vibration reduction mechanism A comprises a connecting plate, a fixed seat, balls, a pressure spring and a rotary mass block; the fixed seat is fixed with a driven shaft, the rotary mass block is installed on an outer ring of the fixed seat, and theplurality of balls are installed between the fixed seat and the rotary mass block in the arc direction, so that the rotary mass block only has the degree of freedom of rotating around a rotary central shaft; the end part of the fixed seat protrudes relative to the end part of the rotary mass block, the connecting plate is fixed on the end part of the fixed seat, and the pressure spring is installed between the connecting plate and the end part of the rotary mass block; and the semi-vibration reduction mechanism A and the semi-vibration reduction mechanism B are fixed through the connecting plate. When the system is in a rated operation condition, the device can obviously reduce the problems of medium-high frequency vibration and noise caused by the rotation of a gear shaft in a gear transmission system.

Description

technical field [0001] The invention relates to a gear transmission device, in particular to a gear transmission device with a dynamic damping function. Background technique [0002] The vibration and noise problems of gearboxes have a long history and have not been well resolved so far. In products in the civilian field, it directly affects the stability and reliability of equipment operation. In the military field, its role is even more important. Taking ships as an example, the vibration and noise levels of the gearbox directly determine its transmission distance, which means the distance it can be detected by the enemy. The greater the vibration and noise, the easier it is to be detected by the enemy. On the contrary, if the noise and vibration of the enemy ship are smaller, it will be more difficult for our side to detect. Therefore, whether it is in the civilian field or the military field, how to reduce the vibration and noise of the transmission system is a problem...

AI Technical Summary

Problems solved by technology

[0003] The vibration and noise in the gear transmission system mainly come from the vibration generated when the gear teeth mesh and the vibration generated by the gear shaft when it rotates. Strong vibration and noise issues
