Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0011] Referring to the drawings, this embodiment includes a cage body 5, the cage body 5 includes an alloy steel substrate 4, the alloy steel substrate 4 is provided with a groove 2, and the surface of the alloy steel substrate 4 and the surface of the groove 2 are sprayed with a layer Ceramic coating3.

[0012] The thickness of the ceramic coating 3 is 120 μm.

[0013] When the bearing 1 is in operation, due to the function of the groove 2, it is beneficial to avoid surface-to-surface contact between the cage 5 and the bearing 1. With the injection of the lubricating medium, it is conducive to the contact between the cage 5 and the bearing 1. Forming an oil film, and because the friction coefficient of the ceramic coating 3 is small, it is beneficial to reduce the friction between the cage 5 and the lubricating medium, does not affect the lubricating...

Abstract

The invention relates to an anti-wear bearing retainer, which comprises a retainer body. The retainer body comprises an alloy steel matrix, the alloy steel matrix is provided with a groove, and both the surface of the alloy steel matrix and the surface of the groove are sprayed with a ceramic coating. The invention has the advantages of good internal toughness and high surface strength; and the alloy steel is adopted to substitute copper as the retainer matrix, thereby being conducive to the reduction of the manufacturing cost.

Description

technical field [0001] The invention relates to a retainer, in particular to an anti-wear bearing retainer. Background technique [0002] The main bearing of the fan is a key component of the wind turbine. Its safe and reliable operation is directly related to the performance of the entire fan. To ensure the safe and reliable operation of the bearing, it must be ensured that the bearing is well lubricated during operation; usually the lubricating medium It is very sensitive to impurities, and a small amount of metal particles may cause the performance of the lubricating medium to decrease, so it is particularly important to reduce the wear between various metal parts. The main bearings of existing wind turbines often use copper cages, and the copper powder produced during the operation will significantly reduce the lubricating performance of the lubricating medium; in addition, the manufacturing cost of copper cages is high, accounting for more than 30% of the total cost of ...
