Problems solved by technology

However, due to working at high altitude, subject to many conditions, the bearings cannot receive daily oiling and maintenance.
Bearings are easily damaged when running without oil, so the safety reliability is poor and the service life is short
In addition, the installation and disassembly of rolling bearings are more troublesome, and the requirements for bearing housings are relatively high.

Embodiment Construction

[0018] Specific embodiments of the present invention will be described below with reference to the accompanying drawings. like figure 1 , 2 , 3, a wind turbine main shaft self-aligning sliding bearing, the overall structure of the bearing can be an upper and lower split structure or an integral structure, depending on the bearing assembly form. There are an outer ring 1 and an inner ring 2, the inner diameter of the outer ring 1 is an inner spherical surface, and the outer diameter of the inner ring 2 is an outer spherical surface, forming a pair of sliding spherical surfaces, which has a centering function. Blind holes are evenly arranged on the outer diameter of the inner ring 2 , and solid lubricants 3 are embedded in the blind holes. The solid lubricant 3 accounts for 18-25% of the outer spherical surface area of ​​the outer diameter of the inner ring 2 . A circular groove 4 is arranged on the outer diameter of the inner ring 2, and a rolling body 5 and a floating limit ...

Abstract

In the invention are disposed an outer ring and an inner race. The inside diameter of the outer ring is an internal spherical surface and the outside diameter of the inner race is an external spherical surface. On the outside diameter of the inner race are uniformly set blind holes with solid lubricant inside and is set a circular recess. A rolling body and a floating spacing pin are disposed between the circular recess and the outer ring. On the inside diameter surface of the inner race is covered a frictional layer made of self-lubricating composite material.

Description

Technical field: [0001] The invention relates to a self-aligning bearing, in particular to a self-aligning sliding bearing for the main shaft of a wind power generator set. Background technique: [0002] At present, most of the domestic wind turbines are in the wild high-altitude working conditions, unattended. The main shaft bearing is the key part of the unit. It not only bears the self-weight of the rotating part, but also under the action of wind force and wind direction, the unit will vibrate greatly, so that the main shaft bearing also bears a large dynamic load and is in a continuous working state for a long time. The existing domestic and foreign wind turbine main shaft bearings all use traditional spherical roller bearings. This kind of bearing can only work safely under the condition of oil lubrication, so the maintenance requirements are strict. However, due to working at high altitude and being restricted by many conditions, the bearing cannot receive daily oil...
