Problems solved by technology

Since the damping value of the traditional damper is usually not adjustable, and experiments have also proved that the appropriate damping value is a range of values, the damping value is too large or too small to achieve the ideal vibration reduction effect

Embodiment Construction

[0025] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0026] combine figure 1 -2, figure 1 In , the relationship between the installation position of the additional system (a new type of broadband adjustable damper) and the main system is given. Figure 2a And Figure 5 shows the assembly diagram and three-dimensional diagram of the additional system, including connecting piece 1, spring 2, elastic column 3, O-ring 4, adjustable friction ring 5, support base 7 and so on. It includes a sealing chamber 6, which is an annular sealing chamber formed by sealing the outer ring of the friction ring and the through hole of the support base through two O-rings.

[0027] Such as figure 1 As shown, the additional system restricts the rotation of the outer ring of the bearing through the interference fit between the hole of the connector and the outer ring of the rolling bearing, and the spring acts as a support to limit the d...

Abstract

The invention discloses a damping device suitable for a rotor bearing system. The damping device comprises a connecting piece, a supporting base, four springs, four elastic columns, eight pins, eight O-shaped sealing rings and four friction rings, and the outer rings of the adjustable friction rings and s through hole of the supporting base are sealed through the two O-shaped sealing rings to form an independent sealing cavity. A hydraulic device conveys hydraulic oil to the sealing cavity through an oil inlet hole preset in the right end face of the supporting base, the deformation amount of the friction rings is controlled by adjusting the oil pressure, therefore the contact area of the friction rings and the elastic columns is adjusted, and then the friction damping of the O-shaped sealing rings and a supporting base hole is affected. The adjustable friction rings which are replaceable and deformable and have the self-following and self-compensating functions are designed for the damper, vibration control with the advantages of being good in vibration reduction effect, high in robustness, longer in service life and the like is achieved, and the production efficiency and the service life of equipment are guaranteed.

Description

technical field [0001] The invention relates to a novel damper suitable for a rotor bearing system, in particular to a vibration damping device applied to the rotor bearing system. Background technique [0002] Suppressing the vibration of the rotor is an effective method to ensure the smooth operation of the equipment and improve the life of the equipment. For example, in the design and processing stage, the traditional way to control rotor vibration is to reduce the original unbalance during processing or to dynamically balance it before leaving the factory. Although these methods can achieve good vibration reduction effects, due to the existence of processing errors and the time-varying and complex environments in actual use, vibration problems are often difficult to solve permanently. With the emergence of various dampers, a new solution is provided to solve the vibration problem that occurs during the use of equipment. An appropriate range of damping values ​​can effe...
