Description

Thrust bearing for wind power generation accelerating box
Technical Field
The utility model relates to a sliding bearing, in particular to a thrust bearing for a wind power generation accelerating box.
Background
The wind driven generator is a device for converting wind energy into electric energy and mainly comprises blades, a generator, mechanical components and electric components. According to the difference of the rotating shafts, wind driven generators are mainly divided into two types, namely a horizontal-axis wind driven generator and a vertical-axis wind driven generator, and the horizontal-axis wind driven generator occupies the main stream position in the market at present. The wind driven generator has a huge structure, wherein the outer diameter of a thrust bearing for a gear box in a mechanical part of the wind driven generator is 200 mm-600 mm or more, which is 10 times larger than that of a conventional thrust bearing, and the conventional powder metallurgy sintering process processing equipment cannot meet the production of similar products due to the huge size and bearing load, so that materials are extremely easy to crush in use and cannot meet the current use requirements.
Disclosure of Invention
The utility model aims to provide a thrust bearing for a wind power generation accelerating box, which has long service life and is more economical.
In order to meet the requirements, the thrust bearing for the wind power generation accelerating box is characterized by being a flat annular thrust bearing, wherein the thrust bearing is made of a steel plate into a flat annular ring, one end face of the annular ring is fused and covered with a copper alloy layer, a plurality of uniformly distributed sinking pits are formed on the copper alloy layer and used for fixing the thrust bearing with a planet carrier through screws, concave oil grooves which are communicated with the inner circumference and the outer circumference are formed on the surface of the copper alloy layer, and oil guiding grooves which are communicated with the inner circumference and the outer circumference are also formed on the surface of the sinking pits.
The copper alloy material is CuSn6.5P0.1 or CuSn12Ni2 or CuSn8Ni1.
According to the thrust bearing for the wind power generation speed-increasing box, which is designed according to the scheme, due to the fact that the copper alloy layer is fused on the steel plate, the strength is greatly reduced compared with the cost of the thrust bearing manufactured by the copper alloy, the strength is greatly improved, and the size of the thrust bearing can be manufactured into an ultra-conventional large sliding bearing without large casting and processing equipment. Has the advantages of simple structure, convenient processing, low manufacturing cost and full lubrication.

Detailed Description
The utility model is further described below with reference to the drawings and specific embodiments.
Fig. 1 is a schematic structural view of a wind power generation speed increasing box. As seen from the figure, the wind power generation speed increasing box mainly includes: fan blade 1, planet carrier 2, planetary wheel shaft 3, planet wheel 4, slide bearing 5, thrust shaft 6 etc.. A thrust bearing 6 for a wind power generation speed increasing box of the present utility model is installed between the planetary wheel 4 on the planetary wheel shaft 3 and the planetary carrier 2, and as shown in fig. 2 to 4, the thrust shaft 6 is a flat annular thrust bearing 6, which is a thrust bearing sliding bearing. The thrust bearing 6 is a flat circular ring 7 made of a steel plate, a copper alloy layer 8 is fused on one end surface of the circular ring 7 in a laser fusion welding mode, the copper alloy material is CuSn6.5p0.1 or CuSn12Ni2 or CuSn8Ni1, the use of copper alloy of other marks is not excluded, a plurality of evenly distributed pits 9 are formed on the copper alloy layer 8, and when in use, the thrust bearing 6 and the planet carrier 2 are fixed by using screws 10 as shown in fig. 5. The surface of the copper alloy layer 8 is provided with a concave oil groove 11 communicated with the inner circumference and the outer circumference, the surface of the pit 9 is also provided with an oil guiding groove 12 communicated with the inner circumference and the outer circumference, and when the planet carrier 2 rotates, the thrust bearing 6 is immersed into the lubricating oil of the speed increasing box, and the lubricating oil is added to the friction surface through the oil groove 10 and the oil guiding groove 11.
