Description
Technical field
The present invention relates to a kind of detachable Hydrodynamic Thrust Bearings devices for reducing hot oil and carrying, and belong to hydrogenerator liquid
Dynamic pressure technical field.
Background technique
In recent years, the water conservancy machinery in China is quickly grown, and in southern over-heating in summer, thrust bearing cooling water temperature is excessively high,
In the event of high temperatures, gap oil film temperature is easily caused to increase, lubricating oil viscosity reduces, and oil film thickness is thinning, leads to part
There is rupture of oil film and dry friction, lead to the generation of tile kilning phenomenon, in order to reduce the generation majority of such case from following
Aspect cooling.One reinforces cooling water circulating speed or film-cooled heat in terms of cooling, and two reduce heat by changing support pattern
Deformation, three by change watt Surface Texture shape or watt material, intuitively reduce heat generate, four increase oil-scraping devices subtracts
Few hot oil carrying amount.Reducing hot oil carrying amount at this stage is directly exactly to increase oil-scraping device, oil-scraping device between two pieces watts
Head uses polytetrafluoroethylene (PTFE).Since oil-scraping device and runner plate are in the process of boundary friction, oil-scraping device is significantly increased
Abrasion, and easy damaged reasoning disk.And in oil-scraping device replacement, complicated oil-scraping device structure will bring a large amount of resource
Waste.
Summary of the invention
In view of the above-mentioned problems, a kind of detachable Hydrodynamic Thrust Bearings device for reducing hot oil and carrying.
Technical solution of the present invention: a kind of detachable Hydrodynamic Thrust Bearings device for reducing hot oil and carrying, it includes frizing
Device pedestal (1), oil-scraping device bracket (2), oil-scraping device rack plate (3), oil-scraping device head (4) spring (5) and bolt
(6), oil-scraping device pedestal (1) is mounted on thrust bearing by hexagon socket head cap screw, it is characterised in that: the oil-scraping device bottom
Seat (1) is by oil-scraping device base body (1-1), bolt hole (1-2), dovetail groove (1-3)；Oil-scraping device bracket (2) passes through dovetail
Shape boss (2-1) is mounted on oil-scraping device pedestal (1), has multiple circular troughs (2-2) and spring on oil-scraping device bracket (2)
(5) it bonds, there are four bolt hole (2-3) for oil-scraping device frame upper；There is slot on oil-scraping device rack plate (3)
(3-1) and four circular through holes (3-2)；Oil-scraping device head (4) has T-shaped structure, and rectangular structure face (4-1) there is guiding to make
With there is stair-step (4-2) to carry out frizing in top structure face；By bolt (6) by oil-scraping device head (4) oil-scraping device branch
Frame cover board (3) and oil-scraping device bracket (2) are mounted together.
Preferably, stair-step (4-2) the ladder height of the oil-scraping device head (4) is no more than 0.2mm, the top rank
Tread has slight draft, and gradient is not more than 0.2 °；Due to work when, bearing can clockwise with rotate counterclockwise, so ladder
It is poised for battle arrangement in face or so.
The present invention has the beneficial effect that
(1) this device is mounted on Hydrodynamic Thrust Bearings pedestal, and when device works, runner plate and oil-scraping device head form one
The very thin oil film of layer reduces the hot oil being tightly attached on thrust disc, thus the hot oil carrying amount being effectively reduced between two bearing shells,
To significantly reduce the temperature rise of oil liquid.
(2) runner plate and oil-scraping device head generate dynamic pressure effect, and oil-scraping device head and thrust collar is made to be chronically at fluid
Friction, thrust collar and oil-scraping device head will not generate biggish abrasion, reduce the replacement on oil-scraping device head.
(3) oil-scraping device head uses cascaded surface, and the minimum oil film of oil-scraping device head and runner plate can be effectively reduced
Thickness.To be effectively reduced the hot oil carrying amount between bearing shell.
(4) oil-scraping device pedestal and oil-scraping device bracket use dovetail groove joint, when so that the oil-scraping device is replaced more
It is convenient, oil-scraping device top need to be only taken out, oil-scraping device head is replaced, reduces employment cost.
