Embodiment Construction

[0020] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0021] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0022] Such as figure 1 As shown, the embodiment of the present invention is a vertical turbine bearing system structure, including shaft 3, bearing body 14, upper spacer sleeve 7, upper nozzle sleeve 9, angular contact ball bearing 12, upper sleeve 15, spring sleeve 16. Spring 17, lower sleeve 18, deep groove ball bearing 19, inner sleeve 29, oil throwing ring 26, lower spacer sleeve 24, etc.

[0023] The upper and lower ends of the bearing body 14 are respectively set in the middle of the shaft 3 through the angular contact ball bearing 12 and the deep groove ball bearing 19, and the compressor impeller 2 and the turbine 21 are installed on the upper and lower ends of the shaft 3 resp...

Abstract

The invention provides a vertical type turbine bearing system. The vertical type turbine bearing system comprises a shaft, a bearing body, upper spacing sleeves, upper nozzle sleeves, angular contactball bearings, upper sleeves, spring sleeves, springs, lower sleeves, deep groove ball bearings, inner sleeves, oil slingers, lower spacing sleeves and the like; and the upper end and the lower end ofthe bearing body are installed on the middle part of the shaft in a sleeving mode through the angular contact ball bearings and the deep groove ball bearings. According to the vertical type turbine bearing system, the axial force in the vertical direction is borne by the angular contact ball bearings, a specially arranged thrust bearing is omitted, and the structure is simplified; and the frictional resistance is reduced due to the fact that the thrust bearing does not exist, and the turbine rotor has a short time form stationary to acceleration.

Description

technical field [0001] The invention belongs to the field of electromechanical technology, and in particular relates to a vertical turbine bearing system. Background technique [0002] The turbine of some engines needs to be placed vertically. Under such conditions, the turbine rotor needs to solve problems such as bearing lubrication and axial thrust. Some vertical turbine bearing systems adopt the method of adding thrust bearings, which is effective but complicated in structure. Contents of the invention [0003] In view of this, the present invention aims to propose a vertical turbine bearing system, which simplifies the structure under the condition that the turbine is lubricated and can bear the vertical axial force. [0004] In order to achieve the above object, technical solution of the present invention is achieved in that way: [0005] A vertical turbine bearing system, comprising a compressor impeller (2), a shaft (3), a bearing body (14) and a turbine (21), th...
