EVALUATION APPARATUS FOR LARGE SIZE BEARINGS

摘要

PURPOSE: An apparatus for evaluating the performance and durability of a large bearing is provided to evaluate the performance of durability of a large bearing by testing a large bearing under the condition of a real aerogenerator. CONSTITUTION: An apparatus(100) for evaluating the performance and durability of a large bearing comprises pitch bearings(110,120), an adapter(130), a rotation unit(170), a front disc(140), and a replication body(150). The pitch bearing ha a ring gear inside. The pitch bearing reproduces a bearing for the rotation blade of an aerogenerator. The adapter is mounted between pitch bearings and operates the pitch bearing. The rotation unit engages with the ring gear to rotate the pitch bearing.
