Problems solved by technology

The speed of these machines is generally high, and the violent vibrations during operation will not only cause damage to the structure or parts of the machine itself, shorten the life, reduce efficiency and other adverse effects, but also affect the surrounding precision instruments and equipment not to work normally or reduce their performance. Sensitivity and precision, the noise generated by the vibration is also very harmful to human health

Embodiment 1

[0019] Such as figure 1 , figure 2 , image 3 As shown, the present invention comprises two fixed rings 1, a plurality of elastic strips 2 and rolling bearings 4; the same circumference of the plurality of elastic strips 2 is equally fixed on the end faces of the two fixed rings 1 to form a squirrel cage, and the shaft 5 in the squirrel cage and The inner ring of the rolling bearing is fixedly connected, and the two fixed rings 1 are fixed on the machine. When the shaft 5 rotates, the outer ring of the rolling bearing contacts with the elastic strip to form a squirrel-cage elastic support.

[0020] Or the outer ring of the rolling bearing is fixedly connected to the bearing support 3, and the bearing support 3 is in contact with the elastic strip 2 to form a squirrel-cage elastic support.

Embodiment 2

[0022] The invention includes two fixed rings, multiple elastic strips and sliding bearings. A plurality of elastic strips are equally fixed on the end faces of two fixed rings on the same circumference to form a squirrel cage. The shaft in the squirrel cage is fixedly connected to the inner sleeve of the sliding bearing. The two fixing rings are fixed on the machine. When the shaft rotates, the outer sleeve of the sliding bearing The sleeve is in contact with the elastic strip to form a squirrel-cage elastic support.

Abstract

The invention discloses a squirrel-cage elastic support. The support comprises two fixing rings, a plurality of elastic strips and a bearing, wherein the plurality of the elastic strips on the same circumference are equationally fixed between the end surfaces of the two fixing rings to form a squirrel cage, a shaft inside the squirrel-cage is fixedly connected with a bearing inner race, a rolling outer ring is contacted with the elastic strips to form the squirrel-cage elastic support; or a bearing outer ring is fixedly connected with a bearing support, and the bearing support is contacted with the elastic strips to form the squirrel-cage elastic support. In the condition of permission and fitness of a mechanical structure, the squirrel-cage elastic support can inhibit bend and deformation of the shaft, reduce vibration of a machine, reduce the damage to the structure or parts, improve the operation stability of the machine, prolong the service life of the machine, reduce noise generated by vibration and the like. The squirrel-cage elastic support can be applied to various rotary machines.

Description

technical field [0001] The invention relates to components in mechanical engineering, in particular to a squirrel-cage elastic support. Background technique [0002] The rotating part contained in the machine is called the rotor. The rotor together with its bearings and supports are collectively referred to as the rotor system. Steam turbines, generators, electric motors, centrifuges, gas compressors, etc. are all typical rotating machines, and the rotor is the main body of their work. The speed of these machines is generally high, and the violent vibrations during operation will not only cause damage to the structure or parts of the machine itself, shorten the life, reduce efficiency and other adverse effects, but also affect the surrounding precision instruments and equipment not to work normally or reduce their performance. Sensitivity and precision, the noise generated by the vibration is also very harmful to human health. Therefore, how to reduce the vibration of the...
