Embodiment Construction

[0022] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not constitute a conflict with each other.

[0023] Such as Figure 1 to Figure 7 As shown, a radial support bearing for a centrifugal compressor of the present invention includes a bearing gland 1, a bearing body 2 and a semicircular bushing 3, and the two ends of the bearing gland 1 are provided with fasteners 11 for compressing the bearing. It is convenient to press the bearing cover 1 on the bearing seat of the compressor. Specifically, the fastener 11 includes a double-ended stud 111, a nut 112, a spring wash...

Abstract

The invention discloses a radial support bearing of a centrifugal compressor. The radial support bearing comprises a bearing gland, a bearing body and a semicircular bush, wherein fasteners used for pressing the bearing are arranged at the two ends of the bearing gland; a fixed part used for preventing the bearing body from rotating is arranged at the top of the bearing gland; the bearing body comprises a bearing bracket, bearing bushes, a vibration mounting plate, an oil sealing ring and a baffle plate; pin holes are formed in the two ends of the bearing bushes; the bearing bushes are located on the bearing bracket and the baffle plate through straight pins; the baffle plate is connected on the bearing bracket through bolts and spring washers, and is located through a taper pin; the oil sealing ring is arranged between the bearing bracket and the baffle plate; the oil sealing ring is hooped through springs; the vibration mounting plate comprises two vibration blocks which have a 90-degree included angle and are connected on the bearing bracket through bolts; an adjusting cushion block used for adjusting the concentricity of a rotor set and a compressor shell is arranged on the semicircular bush; and a circular hole is formed in the top of the bearing bracket. According to the radial support bearing, the self-adaptive adjustment capacity is remarkably strengthened, the operation is more stable and reliable, and the stability and reliability of operation of a centrifugal compressor unit are effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a radial support bearing of a centrifugal compressor. Background technique [0002] At present, domestic and foreign petrochemical, refrigeration and other industries generally use centrifugal compressors to transport and compress various gases, and the bearing system is an essential and important part of centrifugal compressors, which directly determines the operation and stability of centrifugal compressors. The main guarantee of normal operation and service life. At present, the radial bearings of this type of equipment are generally realized by fixed round pads or elliptical pads. The load of fixed bearings has certain limitations, and there is no self-adaptive ability, and the operation stability is poor. The above-mentioned tilting pad bearings are The system is relatively complicated, the structural design and lubricating oil system are cumbersome, the external dimension...
