Embodiment Construction

[0008] see figure 1 , is a specific example of the application of the rotating part support device of the present invention to a vertical long-axis pump. The weight of the whole rotor part and the running axial force of the long-axis pump are borne by the double bearing bracket device of the present invention, and the combined action of the double bearings realizes the axial and radial positioning of the rotating parts.

[0009] The specific implementation is as follows: the upper end of the bearing body 1 is fixedly connected to the bearing bracket 4 with bolts, the outer ring and rolling elements of the thrust self-aligning roller bearing 3 are installed on the bearing body 1, and the inner ring of the thrust self-aligning roller bearing is installed on the journal 7, the deep groove ball bearing 6 is also assembled to the journal 7 and the bearing bracket 4, and then the journal parts are assembled to the bearing body together. After the bearing gland 5 is installed in pla...

Abstract

The invention relates to a support unit of a rotating member for vertical pumps, in which, the bolt at the upper end of the bearing body is connected with the bearing support and the bolt at the lower end of the bearing body is connected a sealed oil drum. Between the bearing body and the journal is mounted a thrust self-aligning roller bearing and between the bearing support and the journal is mounted a ball bearing. The bolt at the upper end of the bearing support is connected with the bearing gland. The journal is connected with drive shaft and the upper end of the journal is connected with a rating nut.

Description

[technical field] [0001] The invention relates to the technical field of supporting devices for rotating parts of pumps, in particular to a supporting device for rotating parts of vertical pumps. [Background technique] [0002] For various vertically installed pumps, the rotating parts are supported in a variety of ways, some use sliding thrust bearings, some use thrust roller bearings, and some have either more complex structures or greater vibration during pump operation. Radial positioning is difficult, making the pump unstable and unreliable. [Content of the invention] [0003] The task of the present invention is to provide a rotating part supporting device, which mainly solves the technical problems in the following three aspects: one is the axial and radial support and positioning of the rotating parts for vertical structure pumps; the other is the pump rotor The axial position can be adjusted up and down according to the needs; the third is a well-designed bearing...
