Embodiment 1

[0053] Embodiment 1: as figure 1 , figure 2 As shown, an input and output shaft vibration attenuation vibration isolation type gearbox includes a gearbox casing 1, an input shaft hole arranged on the gearbox casing, an input shaft 1a, and an input shaft seal end installed on the outer surface of the gearbox casing Cover 3, the output shaft hole arranged on the gear case housing, the output shaft, the output shaft seal end cover installed on the outer surface of the gear case case.

[0054] The input shaft hole and the output shaft hole are respectively provided with vibration-damping sleeves 2 . The vibration-damping sleeve is connected with the gearbox casing by welding. The inner hole of the damping sleeve is a circular hole. The vibration-damping sleeve body includes a support type inner vibration-damping layer 21, a plastic vibration-damping layer 22 and an outer vibration-damping layer 23 from inside to outside. The supporting type inner damping layer and the outer d...

Embodiment 2

[0064] Embodiment 2: the remaining structure of this embodiment is with reference to embodiment 1, and its difference is:

[0065] Such as Image 6 As shown, the bottom of the gearbox housing is also provided with a vibration damping seat 1b. The vibration damping base includes a bottom frame 1b1, a top frame 1b2 for installing the gear box casing, and several hydraulic suspensions arranged on the bottom frame for supporting the top frame. The gearbox casing is connected with the top frame through bolts, and the gearbox casing is located above the top frame.

Abstract

The invention discloses a vibration attenuation and vibration isolation type gearbox for an input shaft and an output shaft capable of obtaining an effect of effectively reducing the noise of the gearbox. The gearbox comprises a gearbox shell, an input shaft hole, an input shaft, an input shaft seal end cover, an output shaft hole, an output shaft and an output shaft seal end cover, wherein the input shaft hole is formed in the gearbox shell, the input shaft seal end cover is arranged on the outer surface of the gearbox shell, the output shaft hole is arranged on the gearbox shell and the output shaft seal end cover is arranged on the outer surface of the gearbox shell; the input shaft hole and the output shaft hole are internally and respectively provided with a vibration attenuation sleeve body, the vibration attenuation sleeve body sequentially comprises a supporting inner vibration attenuation layer, a plastic vibration attenuation layer and an outer vibration attenuation layer from inside to outside, the supporting inner vibration attenuation layer and the outer vibration attenuation layer are respectively made from powder metallurgy materials, and the plastic vibration attenuation layer is made from expanded plastics.

Description

technical field [0001] The invention relates to a gear box, in particular to an input and output shaft vibration attenuation vibration isolation type gear box. Background technique [0002] The vibration and noise of the gearbox are mainly caused by the friction, vibration and collision of the transmission gear. How to effectively reduce the vibration and noise of the gearbox and make it more in line with environmental protection requirements is a key research topic at home and abroad. Although the vibration and noise of the gearbox are mainly caused by the friction, vibration and collision of the transmission gear, due to the large volume of the gearbox casing and the easy amplified vibration of its wall, the gearbox casing is very important for the vibration generated in the entire gearbox. Noise is also affected to some extent. In view of this, some inventors have improved the gearbox housing, but the current improvement to the gearbox housing is often based on "strength...
