Description
Technical field
The utility model relates to a kind of direct-driving electric excitation wind-driven generator bidirectional thrust tapered roller bearing device.
Background technology
Design and installation has stator and rotor in the wind-driven generator; Be to rely on the energy of wind to make the rotor rotation realize the conversion of wind-powered electricity generation energy, in long rotor rotation process, the blast rotation of rotor will inevitably have pressure to bearing; Can produce bearing heating, influence bearing useful life.The prior art wind-driven generator does not design tapered roller bearing device, and its defective is general bearing in rotor rotation process for a long time, and the bear rotor rotational pressure is big, bearing heating, and what influence bearing influences bearing useful life.
The utility model content
The technical problem of the required solution of the utility model is to overcome existing above-mentioned deficiency in the prior art, and provides a kind of simple for structure, the direct-driving electric excitation wind-driven generator bidirectional thrust tapered roller bearing device of long service life.
The utility model solves the problems of the technologies described above and the technical scheme that adopts: a kind of direct-driving electric excitation wind-driven generator bidirectional thrust tapered roller bearing device; It is characterized in that being provided with fixedly axle bed, rotating shaft base, cylindrical roller, taper roller; Cylindrical roller fixedly is installed in the axle bed, taper roller is installed on the rotating shaft base, cylindrical roller and taper roller are complementary; Rotating shaft base is fixedly connected with rotor, and fixedly axle bed is fixedly connected with stator.
The said fixedly axle bed of the utility model is formed by fixedly connecting two identical fixed axis saddles.
The utility model compared with prior art has the following advantages and effect: simple for structure rationally, bearing body can installing/dismounting; Taper roller is cone; Cylindrical roller is cylinder, in rotor rotation process, forms the two-direction thrust bearing structure, prolongs bearing useful life.
Description of drawings
Fig. 1 is the scheme of installation of the utility model embodiment.
Embodiment
Referring to Fig. 1; The utility model embodiment direct-driving electric excitation wind-driven generator bidirectional thrust tapered roller bearing device is provided with fixedly axle bed 5, rotating shaft base 6, cylindrical roller 7, taper roller 8; Fixedly in the axle bed 5 (clamping) cylindrical roller 7 is installed, taper roller 8 is installed on the rotating shaft base 6, cylindrical roller 7 fits like a glove in bearing body with taper roller 8 and is complementary; Form tapered roller bearing device; Tapered roller bearing device snaps between rotor 2 and the stator 3, and rotating shaft base 6 usefulness bolts and rotor 2 are tightened fixing, and two fixedly axle bed 5 usefulness bolts and stator 3 are tightened fixing.
The described bearing body of present embodiment can installing/dismounting, and said fixedly axle bed 5 is formed by fixedly connecting two identical fixed axis saddles, is easy for installation and removal.
The described taper roller 8 of present embodiment is cone, and cylindrical roller 7 is cylinder, in rotor 2 rotary courses, forms the two-direction thrust bearing structure; Cylindrical roller 7 fits like a glove in bearing body with taper roller 8 and is complementary, under the effect of cylindrical roller 7, taper roller 8, and the blast rotational pressure of ability bear rotor 2; Because taper roller 8 has pyramidal structure with bearing body; Make that the linear velocity of roller end face is consistent, avoided the friction of roller and bearing body, prolonged bearing useful life.
The direct-driving electric excitation wind-driven generator is a prior art, can comprise main frame 1, rotor 2, stator 3, and rotor 2 is installed in the main frame 1 with stator 3.
Simple deformation of every the utility model or equivalent transformation should be thought the protection range that falls into the utility model.
