In order to solve the problems of the technologies described above, the commentaries on classics device that disappears of a kind of fixed pitch stall control blade of wind-driven generator provided by the present invention comprising disappear commentaries on classics device ectosome, attachment pegs, joining shaft, deep groove ball bearing; The described commentaries on classics device that disappears is connected between hydraulic cylinder piston rod and the wire rope, described disappearing changes an end of (fixing) connection lightning conductor on the shell of device ectosome one end (wire rope joining end), the big end that described joining shaft is provided with flange places described disappearing to change the inner chamber of device ectosome one end (wire rope joining end), described joining shaft small end connects wire rope, and described disappearing changes the device ectosome the other end (hydraulic cylinder piston rod joining end) by attachment pegs connection hydraulic cylinder piston rod; It is characterized in that, also comprise thrust ball bearing, be fixed with described thrust ball bearing and described deep groove ball bearing from the inside to the outside in the inner chamber of described commentaries on classics device ectosome one end that disappears, described joining shaft is distinguished (fixing) from the inside to the outside and is connected the turning collar of thrust ball bearing and the inner ring of deep groove ball bearing in the inner chamber of described commentaries on classics device ectosome one end (wire rope joining end) that disappears, promptly crossed by joining shaft described thrust ball bearing, the deep groove ball bearing that changes in the inner chamber of device ectosome one end (wire rope joining end) that disappear is chained together;
When wire rope is subjected to torsion and when tendency of twisting, can drive joining shaft axially rotates along joining shaft, be connected in axially rotating along joining shaft with joining shaft of thrust ball bearing on the joining shaft near the inner ring near joining shaft in the turning collar of the big end of joining shaft and the deep groove ball bearing, and this moment thrust ball bearing the retainer ring that changes the outer intracoelomic cavity of device near disappearing and the outer ring of changeing the outer intracoelomic cavity of device near disappearing of deep groove ball bearing keep static, and then disappear and change that the device ectosome is also static not to be changeed.
Further, between the thrust ball bearing retainer ring and deep groove ball bearing outer ring in the inner chamber of described commentaries on classics device ectosome one end (wire rope joining end) that disappears, be provided with the flange that is used for fixing the thrust ball bearing retainer ring; In the inner chamber of described commentaries on classics device ectosome one end (wire rope joining end) that disappears, be provided with the circlip for hole that is used for fixing the deep groove ball bearing outer ring.
Further, described joining shaft is provided with the circlip for shaft that is used for fixing the deep groove ball bearing inner ring.
Further, by joint bolt one end of lightning conductor is fixed on the shell of described commentaries on classics device ectosome one end (wire rope joining end) that disappears.
Utilization the invention provides the commentaries on classics device that disappears that device is connected in the fixed pitch stall control blade of wind-driven generator between hydraulic cylinder piston rod and the wire rope, owing to adopt the rotation connecting structure of two ball bearings (being that thrust ball bearing and deep groove ball bearing use simultaneously), the commentaries on classics device that disappears can be eliminated the warping force of wire rope, and can prevent effectively that hydraulic cylinder piston rod from rotating and lightning conductor rotates, reverses and twines, thereby improve the working life of oil hydraulic cylinder and lightning conductor greatly, and then improve the working life of fan blade.
Description of drawings
Fig. 1 is that disappearing in the embodiment of the invention fixed pitch stall control blade of wind-driven generator changes the device structural drawing.
Embodiment
Below in conjunction with description of drawings embodiments of the invention are described in further detail, but present embodiment is not limited to the present invention, every employing analog structure of the present invention and similar variation thereof all should be listed protection scope of the present invention in.
Referring to shown in Figure 1, the commentaries on classics device that disappears of a kind of fixed pitch stall control blade of wind-driven generator that the embodiment of the invention provided is made up of the commentaries on classics device ectosome 1 that disappears, attachment pegs 2, joining shaft 3, thrust ball bearing 4, deep groove ball bearing 5, circlip for hole 6, circlip for shaft 7, joint bolt 8; The described commentaries on classics device that disappears is connected between hydraulic cylinder piston rod and the wire rope, by joint bolt 8 end of lightning conductor 9 is fixed on the shell of described commentaries on classics device ectosome 1 one ends (wire rope joining end) that disappear, be fixed with thrust ball bearing 4 and deep groove ball bearing 5 from the inside to the outside in the inner chamber of described commentaries on classics device ectosome 1 one ends that disappear, described joining shaft 3 is a T-shaped body cylindrical body, its big end is short, that diameter is bigger cylindrical body, and its small end is long, that diameter is less cylindrical body; Its big end places described disappearing to change the inner chamber of device ectosome 1 one ends (wire rope joining end), its small end is connected in wire rope, described joining shaft 3 connects the turning collar of thrust ball bearing 4 and the inner ring of deep groove ball bearing 5 respectively from the inside to the outside in the inner chamber of described commentaries on classics device ectosome 1 one ends (wire rope joining end) that disappear, promptly crossed by joining shaft 3 thrust ball bearing 4, deep groove ball bearing 5 are chained together; Described disappearing changes device ectosome 1 the other end (hydraulic cylinder piston rod joining end) by attachment pegs 2 connection hydraulic cylinder piston rods; In the inner chamber of described commentaries on classics device ectosome 1 one ends (wire rope joining end) that disappear, be provided with the circlip for hole 6 that is used for fixing deep groove ball bearing 5 outer rings, between thrust ball bearing 4 retainer rings and deep groove ball bearing 5 outer rings in the inner chamber of described commentaries on classics device ectosome 1 one ends (wire rope joining end) that disappear, be provided with the flange that is used for fixing thrust ball bearing 4 retainer rings; On described joining shaft 3, be provided with the circlip for shaft 7 that is used for fixing deep groove ball bearing 5 inner rings.
