Description
Technical field
The present invention relates to a kind of test unit of drive apparatus, particularly a kind of vertical wind power yawing reducer ground loading analog test device.
Background technology
Wind-power electricity generation requires unit to have advance, high reliability, high stability, and the wind-power generating yaw reductor is one of significant components of wind power generating set, is the drive speed reducer of yaw system, vertical being installed in around the genset tower mount.By the driving of its output shaft and yaw system gear wheel engagement, drive the whole cabin orientation of going off course, make impeller be in state down with the wind all the time, to make full use of wind energy, improve generating efficiency.When user mode, yawing reducer matches with control system, when the wind-force set yaw need be gone off course to wind to the wind control system according to the weathervane sensor signal automatically, the necessary electromotor energising rotation of yawing reducer, power is imported yawing reducer, the output shaft gear of yawing reducer drives the yaw system gear wheel, the yaw system gear wheel is arranged on the tower drum flange dish of genset pylon, like this, engagement by yawing reducer output shaft and yaw system gear wheel, make the rotation of yaw system gear wheel, realized the driftage orientation process in whole cabin.Yawing reducer of the prior art generally adopts standard N GW planetary reducer structure, vertical installation.The ground load test of yawing reducer is meant the actual user mode of simulation yawing reducer, promptly under the rotating speed of regulation, consider that the residing environment of wind power generating set is abominable, temperature is very low, windy and dusty, even the high dry running factor of wind field such as many salt fogs, yawing reducer is added that test load turns round, whether every performance index of check yawing reducer reach standard-required.The most important condition of its simulation is a meshing condition, promptly simulates the engaged transmission of output shaft gear and yaw system gear wheel.Yawing reducer ground load testing machine promptly is the dedicated experiments device that carries out this test.
And the ground load testing machine of special vertical yawing reducer is not provided in the prior art at present as yet, normally adopt general reductor charger, it is made up of the direct current of special use or AC motor and erecting frame, shaft coupling, torque rotary speed sensor and erecting frame thereof, shaft coupling, test reductor and erecting frame thereof, shaft coupling, mechanical brake (or electromagnetism dynamometer, or magnetic powder brake) and erecting frame thereof.When adopting this test unit to experimentize, the horizontal installation of tested yawing reducer, connect by shaft coupling with charger, the test supply power is exported by motor, after all driving members transmission, being delivered to energy-dissipating device at last is on the chargers such as mechanical brake, electromagnetism dynamometer or magnetic powder brake, to consume tested reductor institute energy delivered.The defective of this device is: 1, do not provide the test condition of simulation yawing reducer actual user mode, as vertical installation, the output shaft gear greatly mainly service factors of transmission two that are meshed with the yaw system gear wheel.In fact, the vertical reductor of installing and using its duty when horizontal installation test differs greatly, because gear is not installed on the output shaft, directly connect with charger by shaft coupling, with the transmission effect by gear and yaw system gear wheel engaged transmission in the reality use very big difference is arranged, and the performance of gear does not obtain check; Therefore this experimental provision fails truly to reflect each principal element of its user mode, has a strong impact on the accuracy of gained experiment parameter, is difficult to guarantee the realization of experiment purpose.2, the horizontal mounting means floor area of test unit is big, and to the site requirements height, and each test parts is respectively by the supporting of different erecting frame, strict during installation neutralization is cooperated, and is difficult to guarantee installation accuracy, and the time-consuming merit of taking influences efficient.3, its output power is difficult to accurate measurement, can't accurately reflect the influence of the change of power input to output power in experimentation, and power consumption is serious, and charger can produce a large amount of heats in the load test, needs the strong cooling device of configuration.If the employing mechanical brake, brake wear is more serious in its use, often needs more renewal of facing renewal, so slave unit is configured to and loads that to consume the expense that needs all higher.In sum, the test unit of general reductor is difficult to reach the requirement of the ground load test of vertical yawing reducer, test yawing reducer not yet in effect is in the desired high reliability performance of the high dry running of wind field, fail to effectively reduce respective risk, be unsuitable for the ground load test of vertical yawing reducer.
