Abstract
The utility model relates to a supporting structure of a small-sized wind-driven generator, in particular to a supporting structure of the small-sized wind-driven generator. The supporting structure is provided with an upright post casing; an upright post main shaft transversely passes through the upright post casing and is rotatably connected with the upright post casing; an upper bearing and a lower bearing are respectively arranged on the outer wall of the upright post casing at the position of the upright post main shaft, which extends out of the upright post casing; a slip ring is arranged at the connecting part of the upright post main shaft close to the lower bearing and the upright post casing and is connected with the upright post main shaft through a flat key; and an upper bearing cover is arranged at the end part of the upright post main shaft, which extends out of the upright post casing, and is fixedly connected with the upright post casing. The upright post main shaft has stable rotation in the work process, so that the utility model avoids the wear between the upright post main shaft and the upright post casing, greatly prolongs the service life of products and reduces the maintenance cost of equipment.
Description
Technical field
The utility model relates to a kind of wind-driven generator supporting structure, especially small-sized wind power generator supporting structure.
Background technique
The at present common small-sized wind power generator especially supporting structure of the small-sized wind power generator of 200W-300W mostly is the duplex bearing support that single shaft holds the position, material is common engineering plastics, this just has a kind of shortcoming to be exactly: under the rugged environment out of doors, supporting structure is owing to be subjected to the force unbalance easy-rupturing, and material is easily aging, has had a strong impact on the working life of product.
Summary of the invention
For the stability of amplification generator support and the intensity of casing itself, the invention provides a kind of small-sized wind power generator supporting structure.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of small-sized wind power generator supporting structure, has the column housing, laterally be penetrated with the column main shaft and the column housing is rotationally connected at the column housing, stretch out at the column main shaft on the column outer wall at column housing place and be respectively arranged with upper bearing and the next bearing.Support by the duplex bearing that adopts the peaceful weighing apparatus of single shaft of duplex bearing position up and down to support to substitute original single shaft to hold the position, balance the radially additional torque that in rotary course, produces of wind-driven generator because of the imbalance that supports.
In order to prevent to produce wearing and tearing at operation process center pillar main shaft and column housing, further: be provided with slip ring near the column main shaft of the next bearing and the joint of column housing, slip ring is connected by flat key with the column main shaft, effectively like this avoided the column main shaft directly to contact and make the column main shaft produce wearing and tearing, reduced cost of equipment maintenance with the column housing.
Enter in the upper bearing for fear of dust acrobatics etc. and influence the smooth operation of upper bearing, more further: the end of stretching out the column housing at the column main shaft is provided with upper ball cover, and upper ball cover is fixedlyed connected with the column housing.
In order effectively to solve the material ageing problem under rugged environment, strengthened the tensile strength of material, further: described column housing is the one-body molded housing of pack alloy material, promptly material adopts YL108.Efficiently solve the material ageing problem under rugged environment, and strengthened the tensile strength of material greatly, the tensile strength of YL108 is 210-240MPa, and the tensile strength of Nylon is 40-43MPa, and its tensile strength has increased 5-6 doubly.
The utility model modern design, simple in structure, the column spindle operation is steady in the course of the work, has avoided the wearing and tearing between column main shaft and the column housing, in the working life of having improved product greatly, has reduced the maintenance cost of equipment.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural representation.
Among the figure: 1 column housing, 2 column main shafts, 3 upper bearings, 4 the next bearings, 5 slip rings, 6 flat keys, 7 upper ball covers.
Embodiment
A kind of small-sized wind power generator supporting structure as shown in the figure has column housing 1, is the one-body molded housing of pack alloy material.Laterally be penetrated with column main shaft 2 at column housing 1 and be rotationally connected, stretch out at column main shaft 2 on column housing 1 outer wall at column housing 1 place and be respectively arranged with upper bearing 3 and the next bearing 4 with column housing 1.Be provided with slip ring 5 near the column main shaft 2 of the next bearing 4 and the joint of column housing 1, slip ring 5 is connected by flat key 6 with column main shaft 2.The end of stretching out column housing 1 at column main shaft 2 is provided with upper ball cover 7, and upper ball cover 7 is fixedlyed connected with column housing 1.
