Abstract
The utility model belongs to the technical field of wind power bearings, and mainly relates to a wind power pitch bearing provided with a retainer friction block, which comprises a bearing outer ring, a bearing inner ring and a retainer assembled between the bearing outer ring and the bearing inner ring; the joint surfaces of the bearing outer ring, the bearing inner ring and the retainer form a guide surface for mounting the retainer; the guide surface is embedded with a friction block for slowing down the deformation of the retainer, and the friction block protrudes out of the corresponding guide surface. The utility model realizes that the friction block with the hardness close to that of the retainer is arranged on the guide surface of the retainer of the bearing, so that the friction block and the retainer are mutually collided and rubbed, the deformation and abrasion degree of the retainer are greatly reduced, the breakage and failure of the retainer are prevented, and the service life of the wind power variable pitch bearing is effectively prolonged.
Description
Technical Field
The utility model belongs to the technical field of wind power bearings, and mainly relates to a wind power pitch bearing provided with a retainer friction block.
Background
With the development of the wind power industry in recent years, the capacity of a wind generating set is continuously increased, and the requirement on the service life of a wind power bearing is correspondingly improved. In the prior art, the service life of a bearing retainer is a main consideration index of the service life of a bearing in the normal operation process of a wind power pitch bearing. After the wind power variable pitch bearing raceway is subjected to heat treatment, the hardness of the guide surface of the retainer on the raceway edge is higher than that of the retainer, the retainer and the guide surface are mutually rubbed and collided in the bearing operation process, the retainer is easy to deform and wear due to low hardness and even breaks, and the retainer can cause the blocking of a rolling body after being broken, so that the bearing fails.
SUMMERY OF THE UTILITY MODEL
In order to overcome the technical problem, the utility model aims to provide a wind power pitch bearing provided with a friction block of a retainer.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a wind power variable pitch bearing provided with a friction block of a retainer is provided with a bearing outer ring, a bearing inner ring and the retainer assembled between the bearing outer ring and the bearing inner ring; the method is characterized in that: the joint surfaces of the bearing outer ring, the bearing inner ring and the retainer form a guide surface for mounting the retainer; the guide surface is embedded with a friction block for slowing down the deformation of the retainer, and the friction block protrudes out of the corresponding guide surface.
The hardness of the friction block is matched with that of the retainer.
According to the wind power pitch bearing provided by the utility model, in the bearing operation process, the retainer and the friction block are mutually rubbed and collided, so that the deformation and abrasion degree of the retainer are greatly reduced, the breakage and failure of the retainer are prevented, and the service life of the wind power pitch bearing is effectively prolonged.
Drawings
FIG. 1 is a cross-sectional view of a wind power pitch bearing.
FIG. 2 is a partial enlarged sectional view of a wind power pitch bearing.
In the figure: 1. bearing outer ring, 2, friction block, 3, retainer, 4, bearing inner ring, 5 and rolling body.
Detailed Description
The utility model is described with reference to the accompanying drawings and specific examples:
a wind power pitch bearing provided with a friction block of a retainer is provided, and the bearing is provided with a bearing outer ring 1 and a bearing inner ring 4; a retainer 3 is arranged in a gap between the bearing outer ring 1 and the bearing inner ring 4; the rolling bodies 5 are assembled in the raceways of the bearing outer ring 1 and the bearing inner ring 4; the rolling bodies 5 are equidistantly spaced by the retainer 3, so that the adjacent rolling bodies 5 are prevented from being directly contacted, and the rolling bodies 5 are guided and driven to roll in the correct roller path; the friction block 2 is arranged on the retainer guide surfaces of the bearing outer ring 1 and the bearing inner ring 4, the retainer guide surfaces slightly protrude after the installation, and the retainer and the friction block rub and collide with each other in the bearing operation process.
The friction block with the hardness close to that of the retainer is arranged on the guide surface of the retainer of the bearing, so that the friction block and the retainer are mutually collided and rubbed, the deformation and the abrasion degree of the retainer are greatly slowed down, the retainer is prevented from being broken and losing efficacy, and the service life of the wind power pitch bearing is effectively prolonged.
Claims (2)
1. A wind power variable pitch bearing provided with a friction block of a retainer is provided with a bearing outer ring, a bearing inner ring and the retainer assembled between the bearing outer ring and the bearing inner ring; the method is characterized in that: the joint surfaces of the bearing outer ring, the bearing inner ring and the retainer form a guide surface for mounting the retainer; the guide surface is embedded with a friction block for slowing down the deformation of the retainer, and the friction block protrudes out of the corresponding guide surface.
2. The wind power pitch bearing with the holder friction block mounted thereon according to claim 1, wherein: the hardness of the friction block is matched with that of the retainer.
