WO2012152143A1 - Adaptive Rotary Device For Solar Tracking And Dealing Method Thereof - Google Patents

Figs. 1 and 2, usually adopts a structure in which an exterior tooth type single-row 4-level contact ball kind slewing bearing cooperates with a worm, and the driving mode is a single motor drive to understand a solar battery module pair. 0. 1-0. 2 degrees, though the higher precision slewing assist can better reduce the gap worth, however the fee is expensive, which is not conducive to popularization and software; Within the long-term out of doors operation of the one-motor-driven turntable, the gap worth will regularly improve as a result of components corresponding to wind load and operating wear, and it can't be robotically compensated. Due to this hole, the solar tracker cannot obtain the tracking without gaps, which will cause the monitoring accuracy of the solar tracker to be improved, and the gap will progressively enhance with the passage of time, and at last the service life will be diminished due to the lower of tracking accuracy. The graceful working of the balls is poor.



Under the influence of the wind load, the slewing assist system causes all the solar tracker to vibrate back and ItagPro forth as a result of existence of the gap, in order that the worm and worm contact surfaces collide with one another. Produce "pitting" phenomenon, accelerate the harm of tools, and the service life of solar tracking tools is usually required to be 2.0, more than one year, the service life of the slewing help with such construction is difficult to satisfy the necessities, and how to protect the Taihang tracking system the lengthy-term stable operation without clearance cost, has been a major drawback areas of monitor design. An adaptive slewing machine for solar monitoring of the current invention comprising an azimuth slewing assist and/or a top angular slewing support, the azimuth slewing help and/or the height angular slewing support comprising a turntable housing, ItagPro A turbine is disposed in the turntable housing, and no less than two worms are disposed across the turbine. The plurality of worms are simultaneously meshed with the turbine, and at totally different time phases and ItagPro at different rotational speeds, the same development is used to appreciate the turbine drive without gaps.



At the least two worms are disposed around the turbine, and the plurality of worms are concurrently meshed with the turbine, so that the construction of the plurality of worms can be controlled, and when the worm drives the turbine to rotate, the plurality of worms are controlled otherwise. Clearance between turbines After being fully eradicated, the worm and the teeth of the turbine match carefully collectively, and at this time, the discharge of the turbine will be launched by the remaining worms (the remaining worms rotate at a decrease pace than the previous worm), and ItagPro the turbine is managed to rotate with out hesitation. Because the gapless rotation between the worm and the turbine might be realized, before the sun tracking system needs to be managed for tracking, the previous worm is used to eliminate the gap. ⁇ ⁇ and the rotational pace distinction ⁇ V between the plurality of worms. ⁇ ⁇ and the rotational velocity difference ⁇



⁇ ⁇ and the pace difference ⁇ V between the power worm and the high quality worm worm. They are the power worm and the high quality management worm. Continuously get rid of the hole between the teeth of the two worms and the teeth of the turbine. When the clearance is totally eradicated, the teeth of the force worm are closely fitted with the teeth of the turbine. The pace is slower, so the gear teeth of the high-quality-tuning worm will even be in shut contact with the gear teeth of the turbine, however the power of the ability worm and the nice-controlled worm acting on the turbine is simply reverse, that's, the gear teeth of the power worm are all the time towards the turbine. If the nice control worm doesn't rotate, the turbine just isn't step by step launched, because of the worm structure. Two worms are organized around the turbine, and the two worms are symmetrically distributed, so that the turbine is restrained by the worm, so that the turbine is completely restrained in the circumferential route, and no vibration or the like happens, in order that the slewing help machine has an extended life.
