Description
Technical field
The invention belongs to technical field of solar utilization technique, particularly to a kind of pivoting support structure being mainly used in field of solar energy on sun tracker.
Background technology
Pivoting support is mainly used on sun tracker in field of solar energy, azimuth or elevation angle to the sun are tracked, simultaneously need to the opposing weight of solar cell array and wind load, working environment be all open air, it is desirable to the slow-speed of revolution, high reliability, the characteristic such as the most non-maintaining, with low cost.
As shown in Figure 1, for traditional solar energy rotation supporting structure, the outer shroud 2 including shell 1 and being arranged in shell 1 and internal ring 3, described outer shroud 2 and internal ring 3 relatively rotate, described outer shroud 2 is driven by worm and gear 7 or other drive mechanisms, it is provided with steel ball 8 between described outer shroud 2 and internal ring 3, described steel ball 8 is arranged on outer shroud 2 and internal ring 3 is collectively forming in raceway, in the relative rotational motion of outer shroud and outer shroud, steel ball carries axial force and tilting moment simultaneously, and all contacts are linear contact lay.
The pivoting support of traditional structure is primarily present following defect: need good lubrication between raceway and steel ball, and raceway processed complex, required precision is high, raceway needs special equipment to be quenched into higher hardness, and there is soft ribbons, and relatively costly, maintenance complexity, needing regular grease up, maintenance workload is big.By the actually used situation analysis to this pivoting support, most of failure causes are lubrication failure.
Summary of the invention
The goal of the invention of the present invention is: for the problem of above-mentioned existence, a kind of simple in construction is provided, without complex profile, without special process equipment, all contact surfaces are face contact, its stressing conditions is greatly improved, and reduces contact surface pressure, and without being quenched into the pivoting support using engineering plastic bearing of higher hardness.
The technical scheme is that and be achieved in that: a kind of pivoting support using engineering plastic bearing, including shell and arrange outer shroud in the enclosure and internal ring, described outer shroud and internal ring relatively rotate, it is characterized in that: between the endoporus and the periphery of internal ring of described outer shroud, be provided with radially location engineering plastics block bearing, upper axial engineering plastics block bearing it is provided with between the upper surface and the inwall of shell of described outer shroud, described internal ring lower end edge its be radially arranged lobe, it is provided with and the ledge structure of lobe corresponding matching in described outer shroud lower end, bottom axial engineering plastics block bearing it is provided with between the lobe and the ledge structure of outer shroud of described internal ring.
The pivoting support of employing engineering plastic bearing of the present invention, it is provided with installation annular groove in described outer shroud upper surface, and described upper axial engineering plastics block bearing is arranged in installation annular groove.
The present invention has combined the carrying to axial force and tilting moment by radially location engineering plastics block bearing and upper and lower part axial engineering plastics block bearing, its overall structure is simple, without complex profile, without special process equipment, all contact surfaces are face contact, stressing conditions is greatly improved, and reduces contact surface pressure, and without being quenched into higher hardness；Wherein, engineering plastics are prone to molding, cheap, have good low rate start performance, and it is non-maintaining at total life cycle, can reach different need for environment by different packing materials, existing engineering plastic bearing compressive property can accomplish, between 50～200Mpa, to fully meet the requirement of strength of solar energy pivoting support, owing to solar energy pivoting support only rotates less than two circles every day, extremely low the lifetime wear extent of 25 years, fully meet life-span and accuracy requirement, be truly realized non-maintaining.
