Abstract
The invention provides a kind of generator tilting bush structure, comprise tilting pad, it is characterized in that: first two pieces of described tilting pads are provided with spring assembly, tilting bush seat is provided with dismounting hole with spring assembly relevant position behind.A kind of generator tilting bush structure provided by the invention overcomes the deficiencies in the prior art, can easily form bearing film, and easy for installation, saved cost.
Description
Technical field
The present invention relates to a kind of generator tilting bush structure, belong to steam turbine generator technical field.
Background technique
In large turbo-type generator, usually adopt round watt, elliptic bush, tilting bush structure, tilting bush is with its good stability extensive use in generator set.When tilting bush size is larger, first tile fragment gravity is comparatively large, can affect to the formation of bearing film.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of formation requirement that can meet dynamo bearing oil film, and convenient generator tilting bush structure of installing.
In order to solve the problems of the technologies described above, technological scheme of the present invention is to provide a kind of generator tilting bush structure, comprise tilting pad, it is characterized in that: first two pieces of described tilting pads are provided with spring assembly, tilting bush seat is provided with dismounting hole with spring assembly relevant position behind.
Preferably, described dismounting hole is tapped hole.
Preferably, described spring assembly comprises spring, and bolt is located at above spring by spring washer, and copper washer is located at below spring washer by Steel Washer.
The spring of a kind of generator tilting bush structure provided by the invention forms supporting force to tile fragment, makes tile fragment deflect an angle, forms oil film wedge thus, make the oil-feed of tilting bush more smooth and easy, can form bearing film more easily; On tilting bush seat, set up dismounting hole makes dismounting overhaul spring easily simultaneously, time saving and energy saving, cost-saving, the dummy shaft device of forgoing in conventional mounting.
A kind of generator tilting bush structure provided by the invention overcomes the deficiencies in the prior art, can easily form bearing film, and easy for installation, saved cost.
Accompanying drawing explanation
Fig. 1 is a kind of generator tilting bush structural representation provided by the invention;
Fig. 2 is the present embodiment medi-spring device schematic diagram;
Description of reference numerals
1-spring; 2-copper washer; 3-Steel Washer; 4-spring washer; 5-bolt; 100-spring assembly.
Embodiment
For making the present invention become apparent, hereby with a preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Fig. 1 is a kind of generator tilting bush structural representation provided by the invention, described a kind of generator tilting bush structure adds spring assembly 100 according to rotor sense of rotation on conventional tilting bush architecture basics on first two pieces of tilting pads, and in tilting bush seat corresponding increase dismounting hole behind.
Composition graphs 1, turns to according to rotor and bore 4-Φ 41.5 spring eye on first two pieces of tilting pad, and simultaneously in the behind of tilting bush seat, the position of mounting spring bores 4-M48 tapped hole equally.Composition graphs 2, after spring 1 is put into spring eye, first put into copper washer 2 with sealing, next puts into Steel Washer 3 and spring washer 4, finally locks with bolt 5.
Spring forms supporting force to tile fragment, makes tile fragment deflect an angle, forms oil film wedge thus, make the oil-feed of tilting bush more smooth and easy, can form bearing film more easily; On tilting bush seat, set up dismounting hole makes dismounting overhaul spring easily simultaneously, time saving and energy saving, cost-saving, the dummy shaft device of forgoing in conventional mounting.
Claims (2)
