Disc spring damper capable of adjusting damping and rigidity

Abstract

The invention relates to a disc spring damper capable of adjusting damping and rigidity. The disc spring damper capable of adjusting damping and rigidity comprises a disc spring, a fixed screw, an inner guide shaft, a bearing, an upper cover plate, an end cover, a locking sleeve, a cylinder block and a base; the cylinder block is fixed on the base; the inner guide shaft is positioned in the cylinder block; the inner guide shaft is connected to the base; the fixed screw is connected into the inner guide shaft; the end cover is arranged at the upper end of the cylinder block; the bearing is fixed between the end cover and the inner guide shaft; the locking sleeve is connected to the outer side of the cylinder block; the upper cover plate is arranged at the upper ends of the end cover and thelocking sleeve; the disc spring is arranged between the inner guide shaft and the cylinder block; the upper and lower ends of the disc spring butt against the end cover and the base; the upper coverplate is used for bearing damped objects; the fixed screw is used for realizing limiting of the damped objects; and the base is used for connecting with a foundation. The disc spring damper capable ofadjusting damping and rigidity has the advantages of damping and rigidity adjustability, high energy consumption capacity, stable performances, convenience to operate, low cost and the like.

Description

technical field [0001] The invention belongs to the technical field of vibration reduction and isolation, in particular to a disc spring damper with adjustable damping and stiffness. Background technique [0002] Vibration widely exists in engineering technology and daily life, and this ubiquitous phenomenon is attracting increasing attention. In engineering, people use the advantages of vibration to develop vibration equipment, such as vibration conveying, vibration screening, vibration grinding, etc., which greatly improve working conditions and increase productivity. However, vibration also has a negative side, which not only affects the service life of machinery and equipment, the performance of instruments and equipment, and the stability of building structures, but also the noise generated by vibration also affects people's work, life and health. Effective isolation control of vibration is a top priority. How to ensure the normal operation of some high-tech, sophisti...

Problems solved by technology

However, the disadvantages of using the wire rope pretension device are: (1) the pretension force of the wire rope is generally 1% to 2% of its breaking force, and it can be seen that the range of change in the pre-stiffness of the disc spring assembly is very small; (2) when it is used When the vibration isolation object vibrates and presses the disc spring assembly, the disc spring moves downward due to elastic deformation, and the wire rope is in a relaxed state. Once the vibration isolation object is buffered upwards, the disc spring assembly actively resets, and the wire rope is suddenly in a tight state. The sudden change in the working state of the wire rope has high requirements on its service life, and there are also certain safety hazards

[0004] At the same time, in modern engineering practice, the requirements for the working frequency band, installation space and temperature and weather resistance of the vibration isolator are getting higher and higher. Conventional linear vibration absorbers often cannot take into account multiple technical indicators. This type of engineering practice Promote the development of nonlinear vibration reduction technology
