Abstract
The invention discloses a slewing bearing provided with engineering plastic bearings. The slewing bearing provided with the engineering plastic bearings comprises an outer shell, an outer ring and an inner ring, wherein the outer ring and the inner ring are arranged inside the outer shell and rotate oppositely, a radial positioning engineering plastic supporting bearing is arranged between the inner hole of the outer ring and the periphery of the inner ring, an upper axial engineering plastic supporting bearing is arranged between the upper end surface of the outer ring and the inner wall of the outer shell, a protruding portion is arranged at the lower end of the inner ring in the radial direction, a step structure correspondingly matched with the protruding portion is arranged at the lower end of the outer ring, and a lower axial engineering plastic supporting bearing is arranged between the protruding portion of the inner ring and the step structure of the outer ring. The slewing bearing provided with the engineering plastic bearings bears axial force and capsizing moment through the radial positioning engineering plastic supporting bearing, the upper axial engineering plastic supporting bearing and the lower axial engineering plastic supporting bearing, is simple in overall structure, is free of a complex surface, does not need special machining equipment, enables all the contact surfaces to be in surface contact, greatly improves stress conditions, reduces pressure of the contact surfaces, and does not need to be quenched to reach a high hardness.
Description
Technical field
The invention belongs to technical field of solar utilization technique, particularly a kind of pivoting support structure be 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, the position angle of the sun or elevation angle are followed the tracks of, need the weight of opposing solar cell array and wind to carry simultaneously, working environment is all outdoor, requires the slow-speed of revolution, high reliability, the characteristic such as substantially non-maintaining, with low cost.
As shown in Figure 1, for traditional sun power rotation supporting structure, the outer shroud 2 comprising shell 1 and be arranged in shell 1 and inner ring 3, described outer shroud 2 and inner ring 3 relatively rotate, described outer shroud 2 is driven by worm and gear 7 or other driving mechanisms, steel ball 8 is provided with between described outer shroud 2 and inner ring 3, described steel ball 8 is arranged on outer shroud 2 and inner ring 3 is formed in raceway jointly, in the relative rotational motion of outer shroud and outer shroud, steel ball carries axial force and upsetting moment simultaneously, and all contacts are linear contact lay.
Mainly there is following defect in the pivoting support of traditional structure: needs good lubrication between raceway and steel ball, and raceway processed complex, accuracy requirement is high, raceway needs specialized equipment to be quenched into higher hardness, and there is soft ribbons, cost is higher, and maintenance is complicated, need regular grease up, maintenance workload is large.By the actual service condition analysis to this pivoting support, most of failure cause is lubrication failure.
Summary of the invention
Goal of the invention of the present invention is: for above-mentioned Problems existing, there is provided a kind of structure simple, without complex profile, without the need to special process equipment, all surface of contact are face contact, its stressing conditions is greatly improved, and reduces surface of contact pressure, and without the need to the pivoting support of the employing engineering plastic bearing that is quenched into higher hardness.
Technical scheme of the present invention is achieved in that a kind of pivoting support adopting engineering plastic bearing, comprise shell and outer shroud in the enclosure and inner ring are set, described outer shroud and inner ring relatively rotate, it is characterized in that: between the endoporus and the periphery of inner ring of described outer shroud, be provided with radial location engineering plastics block bearing, upper axial engineering plastics block bearing is provided with between the upper surface and the inwall of shell of described outer shroud, described inner ring lower end is radially provided with lug boss, described outer shroud lower end is provided with the ledge structure with lug boss corresponding matching, the axial engineering plastics block bearing in bottom is provided with between the lug boss and the ledge structure of outer shroud of described inner 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 on to be installed in annular groove.
The present invention has combined the carrying to axial force and upsetting moment by the axial engineering plastics block bearing of radial location engineering plastics block bearing and upper and lower part, its one-piece construction is simple, without complex profile, without the need to special process equipment, all surface of contact are face contact, stressing conditions is greatly improved, and reduces surface of contact pressure, and without the need to being quenched into higher hardness; Wherein, engineering plastics are easy to shaping, cheap, have good low rate start performance, and it is non-maintaining at total life cycle, can reach different need for environments by different packing materials, existing engineering plastic bearing compressive property can be accomplished between 50 ~ 200Mpa, meets the requirement of strength of sun power pivoting support completely, because sun power pivoting support only rotates less than two circles every day, extremely low the lifetime wear extent of 25 years, meet life-span and accuracy requirement completely, really accomplish non-maintaining.
