Abstract
The utility model discloses a photovoltaic weather-resisting transmission sleeve, which belongs to the field of a photovoltaic technology, and overcomes the defects that transmission type shaft sleeves cannot reach outdoor anti-erosion, waterproof and anti-aging requirements in the prior art. The technical scheme has the essentials as follows: the photovoltaic weather-resisting transmission sleeve comprises a bearing seat and a bearing inner ring, wherein a rolling body is embedded between the bearing seat and the bearing inner ring; the surfaces of the bearing seat and the bearing inner ring are subjected to hot dip galvanizing treatment; sealing rings are arranged on the two sides of a combined part of the bearing seat and the bearing inner ring. The photovoltaic weather-resisting transmission sleeve is mainly used for outdoor photovoltaic transmission equipment.
Description
Technical field
The utility model belongs to a kind of photovoltaic apparatus, specifically, especially designs a kind of photovoltaic high weathering resistance drive sleeve.
Background technique
The today being widely used in various technology, field transmission device become our life must or a scarce part, they and require to have the performance of durability, requiring again has higher protective and erosion resisting, as photovoltaic tracking power station.But in present technology, for not only anti-erosion but also waterproof, age inhibiting transmission class axle sleeve, be all a technological gap at home all the time.
The profile pattern of conventional bearing support and internal structure principle, its outside general employing metal casting is also smeared anticorrosive paint, and inside is bumped into ball bearing.But the coating of housing effect for anticorrosion is very micro-, generally indoor, can use 10-15, the words 2-3 that field is used just there will be the phenomenons such as corrosion in various degree, variable color; The bearing durability that center is bumped into is just poorer, because bearing requires surface accuracy higher, thereby cannot do any preservative treatment, is directly exposed to field, at once will corrosion, and this is completely unacceptable for the photovoltaic industry life-span that requires of 25 years.
Summary of the invention
The utility model provides a kind of photovoltaic high weathering resistance drive sleeve, cannot reach the defect of outdoor anti-erosion, waterproof, anti-aging requirement to overcome transmission class axle sleeve in prior art.
The technical solution adopted in the utility model is: photovoltaic high weathering resistance drive sleeve, comprise bearing support and bearing inner race, between bearing support and bearing inner race, be inlaid with rolling element, bearing support and bearing inner race surface all adopt hot galvanizing to process, and the both sides of the bound fraction of bearing support and bearing inner race are all provided with seal ring.
Two groups of seal rings have all been installed in the both sides of the bound fraction of bearing support and bearing inner race.
Compared with prior art, the beneficial effects of the utility model are:
(1) bearing support of the present utility model and bearing inner race surface are hot galvanizing processing, and its durability is higher;
(2) two groups of seal rings have all been installed in drive sleeve of the present utility model both sides, can guarantee that inner steel ball rolling is not subject to the impact of dust storm and rainwater completely;
(3) the utility model integral body durability under complicated wild environment is strong, effective for resisting of rainwater, dust storm, salt fog.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, bearing support; 2, bearing inner race; 3, seal ring; 4, rolling element.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, photovoltaic comprises the bearing support 1 of outer annular part and the bearing inner race 2 of inner annular part by high weathering resistance drive sleeve, bearing support 1 and bearing inner race 2 surfaces are hot galvanizing and process, the bound fraction of its rotation is provided with a circle rolling element 4 so that it reaches the transmission effect of bearing, its inner rolling element 4 rolls part and adopts precision cutting processing, guarantee its dimensional accuracy and smoothness of operation, what the bound fraction sealing of bearing support 1 and bearing inner race 2 adopted is seal ring 3, optimized scheme is, in the both sides of the bound fraction of bearing support 1 and bearing inner race 2, two groups of seal rings 3 have all been installed, can guarantee that inner steel ball rolling is not subject to the impact of dust storm and rainwater completely.
Claims (2)
