Abstract
The invention belongs to technical field of bearings, propose a kind of bearing, the bearing proposed includes bearing outer ring (1), bearing inner race (3) and the steel ball between bearing inner race and bearing outer ring (2); It is characterized in that: the raceway of described bearing inner race (3), the raceway of bearing outer ring (1) are two roller path structure and spacing between two raceways is 63mm, described steel ball (2) is of a size of φ 44.45mm, the wrapping angle of described bearing is 50 °, the curvature of the raceway of described bearing inner race (3), the raceway of bearing outer ring (1) is 23.11mm, and raceway offset is 0.678mm.A kind of bearing that type of the present invention proposes, the raceway of bearing inner race, the raceway of bearing outer ring are two roller path structure, and adopt steel ball and raceway curvature, offset, the wrapping angle of specific dimensions, significantly promoting the load-carrying properties of bearing when not strengthening bearing boundary dimension, more meeting the usage requirement of wind electricity pitch variable bearings.
Description
Technical field
The invention belongs to technical field of bearings, be specifically related to a kind of bearing, be applicable to wind power system.
Background technique
Bearing is the supporting member in mechanical transmission mechanism, and for determining running shaft and other part relative movement position, its quality and bearing capacity directly affect the service behaviour of mechanical complete machine, is driven the motion of fan blade by the running of bearing.Bearing, when guaranteeing that load-carrying properties meet usage requirement, more needs the size ensureing self to adapt to the spatial structure used.Wind power system is while improving constantly generated output, and the space in cabin can not significantly promote, but the axle of pitch variable bearings, radial carrying and tilting moment enlarge markedly, and this proposes higher standard to pitch variable bearings.
Summary of the invention
In order to overcome above-mentioned technical problem, the object of the invention is to propose a kind of bearing.
To achieve these goals, the present invention adopts following technological scheme:
A kind of bearing, described bearing is wind-powered electricity generation pitch variable bearings, and described bearing includes bearing outer ring, bearing inner race and the steel ball between bearing inner race and bearing outer ring; The raceway of described bearing inner race, the raceway of bearing outer ring are two roller path structure; Spacing between two raceways of described bearing inner race, two raceways of bearing outer ring is 63mm; Described steel ball is of a size of φ 44.45mm, and the wrapping angle of described bearing is 50 °, and the radius of curvature of the raceway of described bearing inner race, the raceway of bearing outer ring is 23.11mm, and raceway offset is 0.678mm.
A kind of bearing that the present invention proposes, the raceway of bearing inner race, the raceway of bearing outer ring are two roller path structure, and adopt steel ball and raceway curvature, offset, the wrapping angle of specific dimensions, significantly promoting the load-carrying properties of bearing when not strengthening bearing boundary dimension, more meeting the usage requirement of wind electricity pitch variable bearings.
Accompanying drawing explanation
Fig. 1 is schematic cross-section of the present invention.
Fig. 2 is the structural representation of raceway in the present invention.
In figure: 1, bearing outer ring, 2, steel ball, 3, bearing inner race.
Embodiment
With specific embodiment, the present invention is illustrated by reference to the accompanying drawings
:
As shown in Figure 1, a kind of bearing, described bearing includes bearing outer ring 1, bearing inner race 3 and the steel ball between bearing inner race 1 and bearing outer ring 32; Composition graphs 2, the raceway of described bearing inner race 3, the raceway of bearing outer ring 1 are two roller path structure and spacing between two raceways is 63mm; Described steel ball 2 is of a size of φ 44.45mm, and the wrapping angle of described bearing is 50 °, and the radius of curvature of the raceway of described bearing inner race 3, the raceway of bearing outer ring 1 is 23.11mm, and raceway offset is 0.678mm.
