Abstract
The utility model discloses an unbalanced tilting-pad thrust bearing, which comprises a bearing seat, tilting pads, set screws, wear-resistant coating and a cylindrical pin. The bearing seat is provided with the tilting pads; the tilting pads are of mobile type structure with supporting lugs on the inner surface and wear-resistant coating on the outer surface; the set screws are arranged between the tilting pads; the cylindrical pin is arranged on the bearing seat. The utility model adopted the tilting pads as mobile type structure can regulate the slant automatically to form a converging geometric-form, so that the stationary stabilization oil film can be made to keep the bearing in a superior lubricating station all the time. The utility model has characterized in hydraulic bearing performance, mobile type tilting pad structure, simple structure, self-regulating the axial direction balance and the uniform stress between tiles, and extending the service life of the thrust bearing. The utility model mainly applies to the charge pump assembly of petroleum extraction, etc.
Description
One, technical field:
The utility model relates to bearing, particularly a kind of unbalanced watt thrust bearing that can incline.
Two, background technique:
At present, the thrust bearing that Electric Submersible Pump Unit is used is fixed tile fragment structure, owing to there is not the convergent geometrical shape, import and export all smallly, be difficult to form fixedly oil film, make bearing be in the boundary friction state all the time, therefore, bearing capacity is little, power loss is big, noise is big, the life-span is short;
Three, summary of the invention:
The purpose of this utility model is shortcoming or the deficiency that exists at above-mentioned prior art, and a kind of improved, outstanding good unbalanced of performance watt thrust bearing that can incline is provided.
The unbalanced described in the utility model watt thrust bearing that can incline comprises bearing support, tilting pad, positioning screwn, wear resistant coating and straight pin.Install tilting pad on the described bearing support, this tilting pad is a movable structure, and its internal surface is provided with supporting lug, and outer surface is provided with wear resistant coating, and described positioning screwn is installed between tilting pad, and straight pin is installed on bearing support.Wear resistant coating can be materials such as pottery, graphite, polyether-ether-ketone, Babbitt and tin bronze, can select according to different Environmental Conditions and load.
Wherein, the supporting lug on the described tilting pad internal surface is a cuboid shape, is connected as a single entity with bearing slider.
The utility model has following advantage compared with prior art:
1, adopts the movable tile fragment of eccentric, regulate its inclination automatically, have the convergent geometrical shape, form stable oil film, make bearing be in superior lubricating status all the time, have the characteristic of fluid bearing;
2, adopt the movable tile fragment of eccentric, regulate longitudinal balance between each tile fragment and evenly stressed automatically, the working life of raising thrust bearing;
3, simple in structure, can select required different tile fragment off-centre and the wear resistant coatings of tile fragment surfacing design according to concrete Environmental Conditions and load requirement, satisfy its usage requirement, reduce production costs;
4, can design corresponding oil groove according to what of tile fragment number, guarantee sufficient lubricating oil and heat radiation in time.
Four, description of drawings:
Fig. 1 is the utility model structural representation
Fig. 2 is for pressing structure schematic side view shown in Figure 1
Five, specific embodiment:
With reference to Fig. 1-Fig. 2, a kind of unbalanced watt thrust bearing that can incline comprises bearing support 1, tilting pad 2, positioning screwn 3, wear resistant coating 5 and straight pin 4.Install tilting pad on the bearing support, this tilting pad is a movable structure, and its internal surface is provided with supporting lug 6, and outer surface is provided with wear resistant coating 5, and described positioning screwn 3 is installed between tilting pad 2, and straight pin 4 is installed on bearing support 1.Wear resistant coating can be materials (being expressed as Babbitt among the figure) such as pottery, graphite, polyether-ether-ketone, Babbitt and tin bronze, can select according to different Environmental Conditions and load.
Supporting lug 6 on tilting pad 2 internal surfaces is a cuboid shape, is connected as a single entity with tilting pad.
