Abstract
The utility model relates to a bearing pedestal with a dual-rotor lock symmetrical structure, and belongs to the technical field of wind power generation. In the technical scheme, the bearing pedestal with the dual-rotor lock symmetrical structure comprises the bearing pedestal (5), rotor lock mounting holes (1), a shaft sleeve (2) and bases (3), the two bases (3) are arranged on two sides of the bearing pedestal (5) symmetrically; the two rotor lock mounting holes (1) are also formed in two sides of the bearing pedestal (5) symmetrically and are formed above the two bases (3); and the shaft sleeve (2) is arranged in the middle of the bearing pedestal. Compared with the prior art, the utility model has the advantages that: besides the fundamental function of transferring loads of a main shaft to a main machine frame, the bearing pedestal has a function of locking a wind wheel by rotor locks arranged on two sides symmetrically; and the rotor locks arranged on two sides symmetrically are easy to center when a locking command is executed, so that the requirement of more and more loads can be met, the local stress of arranging a matrix component by the rotor locks is reduced, the service life is prolonged, and the safety of a unit is improved.
Description
Technical field
The utility model relates to a kind of band double rotor lock symplex structure bearing support, belongs to technical field of wind power generation.
Background technique
The bearing support of wind power generating set is the strength member that connects main shaft and mainframe, and its function is that the load of main shaft is passed to the cabin mainframe.Along with the increase of wind-powered electricity generation unit capacity, the load that the rotor lock bears during the wind wheel locking is increasing, and the single rotor lock has been not enough to guarantee unit safety property, the generation that causes the accident easily.
The model utility content
The utility model purpose provides a kind of band double rotor lock symplex structure bearing support; Be fit to big capacity wind-powered electricity generation unit; Lock and resist big load through being installed on the bearing support double rotor, realize the purpose of locking wind wheel, guarantee unit safety property; Prevent the generation of accident, solve the problems referred to above that exist in the background technique.
The technological scheme of the utility model is: a kind of band double rotor lock symplex structure bearing support; Comprise bearing support, rotor lock mounting hole, axle sleeve, base; Two bases are symmetricly set on the both sides of bearing support; Two rotor lock mounting holes also are symmetricly set on the both sides of bearing support, and two rotor lock mounting holes are separately positioned on the top of two bases, and axle sleeve is arranged on the centre of bearing support.
Said base is provided with bolt hole, and base is fixed on the blower fan mainframe through bolt hole.
Main shaft is installed in the axle sleeve of bearing support.The rotor lock is installed in respectively in two rotor lock mounting holes, and when starting the rotor lock, the rotor lock action simultaneously that bilateral symmetry is installed is inserted into spring bolt in the jack of brake disc, with the wind wheel locking, guarantees that wind wheel remains static.
The beneficial effect of the utility model is: compare with existing bearing support, this bearing support can also be locked the function that realizes locking wind wheel through the rotor that bilateral symmetry is installed except possessing the fundamental function of main shaft load being passed to mainframe.The rotor lock that bilateral symmetry distributes, easy centering when carrying out the locking order; Can satisfy increasing load requirement, reduce the localized stress that the rotor lock is installed the parent parts, increase the service life, improve unit safety property.
Description of drawings
Accompanying drawing 1 is the utility model example structure schematic representation;
Among the figure: rotor lock mounting hole 1, axle sleeve 2, base 3, bolt hole 4, bearing support 5.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further through embodiment.
A kind of band double rotor lock symplex structure bearing support; Comprise bearing support 5, rotor lock mounting hole 1, axle sleeve 2, base 3; Two bases 3 are symmetricly set on the both sides of bearing support 5; Two rotor lock mounting holes 1 also are symmetricly set on the both sides of bearing support 5, and two rotor lock mounting holes 1 are separately positioned on the top of two bases 3, and axle sleeve 2 is arranged on the centre of bearing support 5.
Said base 3 is provided with bolt hole 4, and base is fixed on the blower fan mainframe through bolt hole.
Main shaft is installed in the axle sleeve of bearing support.The rotor lock is installed in respectively in two rotor lock mounting holes, and when starting the rotor lock, the rotor lock action simultaneously that bilateral symmetry is installed is inserted into spring bolt in the jack of brake disc, with the wind wheel locking, guarantees that wind wheel remains static.
