Description
Technical Field
The utility model relates to a wind-powered electricity generation gear box, in particular to megawatt level wind-powered electricity generation gear box torsion arm.
Background
With the development of economy and the increasing importance of the environment protection of the country, the society is actively developing new energy industries, wherein wind energy is used as a new energy source, and the proportion of the wind energy occupying the energy source is higher and higher in recent years. With the increasing of the wind power generation power, the requirement on the wind power gear box which is the core component of the wind driven generator is also increased.
Along with the increase of wind power generation power, the moment of torsion of ring gear transmission increases, and there is the risk in torque arm back shaft and flange joint department, and the blade increase causes the increase of torque arm bearing capacity, can cause the ovality increase of torque arm bearing frame, and the torque arm size increases, and the axial distance increase of bearing frame to the supporting seat center has together with torque arm bearing capacity, has increaseed the moment of flexure that makes the torque arm upset.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing a megawatt level wind-powered electricity generation gear box torsion arm improves torsion arm's bending resistance.
The technical scheme is as follows: a megawatt level wind-powered electricity generation gear box torsion arm, including connecting the casing, connecting the bearing frame that the casing includes the flange of outer lane, the web of well circle and inner circle, integrated into one piece has the boss on the surface between the web of well circle and the bearing frame of inner circle, and the part of boss extends to the flange edge.
Furthermore, the reinforcing block comprises a reinforcing rib arranged on the surface of the bearing seat and two pairs of corresponding convex blocks arranged between the web plate of the middle ring and the bearing seat of the inner ring, and the convex blocks and the reinforcing rib are attached.
Further, the thickness of the part of the bump at the flange is smaller than that of the other part of the bump.
Furthermore, the surface of the convex block is arranged in an arc-shaped inclined mode, and the convex block inclines from the flange to the bearing seat.
Further, the edge portion of the projection is provided with a groove for reducing the overall mass of the torsion arm.
Has the advantages that: compared with the prior art, the utility model: the flange connected with the supporting seat is thickened, so that the bending resistance of the torsion arm can be improved, the inclination angle of the bearing seat of the torsion arm is reduced, the matching state of the bearing seat and the bearing can be improved, and the service life of the bearing is prolonged; the projections extend from the bearing seats to the flanges to enhance the bending resistance of the torsion arm.
Drawings
FIG. 1 is a schematic diagram of a torsion arm structure of a megawatt wind power gear box.
Detailed Description
As shown in figure 1, the torsion arm of the megawatt wind-power gear box comprises a connecting shell 1, wherein the connecting shell 1 comprises a flange 11 of an outer ring, a web 12 of a middle ring and a bearing seat 13 of an inner ring, a reinforcing block 2 is integrally formed on the surface between the web 12 of the middle ring and the bearing seat 13 of the inner ring, and part of the reinforcing block 2 extends to the edge of the flange 11.
The reinforcing block 2 comprises a reinforcing rib 21 arranged on the surface of the bearing seat 13 and two pairs of convex blocks 22 correspondingly arranged between the web 12 of the middle ring and the bearing seat 13 of the inner ring, and the convex blocks 22 and the reinforcing rib 21 are attached. The surface of the projection 22 is arc-shaped and inclined, and the projection 22 is inclined from the flange 11 to the bearing seat 13.
The flange 11 connected with the supporting seat is thickened, so that the bending resistance of the torsion arm can be improved, the reduction of the inclination angle of the bearing seat 13 of the torsion arm can improve the matching state of the bearing seat 13 and the bearing, and the service life of the bearing can be prolonged.
Bearing transmission bearing power arrives the torque arm, and bearing frame 13 can form the ellipse, and the atress direction is tensile, and bearing frame 13 and bearing cooperation become loose, and the compression of non-atress direction, bearing roller can receive bigger pressure, and strengthening rib 21 is favorable to reducing bearing frame 13 ovality, improves the atress condition of the whole circle of bearing, improves the bearing life-span.
The torsion arm is subjected to lightweight treatment on the premise of not influencing the strength of the torsion arm. The lug 22 is provided at its edge portion with a groove 3 for reducing the overall mass of the torsion arm or at the flange 11 portion of the lug 22 having a smaller thickness than the other portion of the lug 22, and the torsion arm is lightened by reducing the thickness of the lug 22 and grooving the lug 22.
