Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] figure 1 It is an assembly diagram of the gear transmission system. It can be seen that the system mainly consists of driving gears, driving bearings, driving shafts, driven shafts, driven bearings, driven gears and dual-frequency vibration damping assemblies. figure 2 It is an exploded view of the system. In the figure, the driving bearing 5, the driving gear 2 and the driving shaft 1 form the driving gear-shaft system, and the driven bearing 6, the driven shaft 4 and the driven gear 3 form the driven gear-shaft system. The dual-frequency damping module is installed on the web of the driven gear 3 through bolts.

[0034] image 3 It is the assembly diagram of the vibration damping system, which is mainly composed of three parts: the meshing frequency vibration damping assembly, the shaft motion frequency vibration damping assembly and the base. F...

Abstract

The invention discloses a high-damping dual-frequency power damping gear transmission device. The high-damping dual-frequency power damping gear transmission device comprises an engagement frequency damping mechanism and a shaft driving rotating frequency damping mechanism. The engagement frequency damping mechanism comprises first compression springs, a guide rod and a mass block. The guide rod is sleeved with the mass block. The two ends of the guide rod are fixed to a pair of support frames. The first compression springs are arranged between the mass block and the support frames. The shaftdriving rotating frequency vibration damping mechanism comprises the mass block, a bearing and second compression springs. The outer side of the bearing is sleeved with the mass block. An inner ring of the bearing is mounted on a bearing mounting sleeve of a base. Upper compression spring seats and lower compression spring seats are arranged on the inner side of the mass block. Middle compressionspring seats are arranged between the upper compression spring seats and the lower compression spring seats. The second compression springs are arranged between the middle compression spring seats andthe upper compression spring seats and between the middle compression spring seats and the lower compression spring seats. By the adoption of the high-damping dual-frequency power damping gear transmission device, under the rated operating condition of a system, the problems of medium-high-frequency vibration and noise caused by the gear engagement vibration and shaft rotation vibration in the gear transmission system can be remarkably reduced.

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 a ship 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 probl...
